This will allow you to toggle the debug output for different parts of your module as well as the module as a whole. + +Example [_app.js_](./examples/node/app.js): + +```js +var debug = require('debug')('http') + , http = require('http') + , name = 'My App'; + +// fake app + +debug('booting %o', name); + +http.createServer(function(req, res){ + debug(req.method + ' ' + req.url); + res.end('hello\n'); +}).listen(3000, function(){ + debug('listening'); +}); + +// fake worker of some kind + +require('./worker'); +``` + +Example [_worker.js_](./examples/node/worker.js): + +```js +var a = require('debug')('worker:a') + , b = require('debug')('worker:b'); + +function work() { + a('doing lots of uninteresting work'); + setTimeout(work, Math.random() * 1000); +} + +work(); + +function workb() { + b('doing some work'); + setTimeout(workb, Math.random() * 2000); +} + +workb(); +``` + +The `DEBUG` environment variable is then used to enable these based on space or +comma-delimited names. + +Here are some examples: + +screen shot 2017-08-08 at 12 53 04 pm +screen shot 2017-08-08 at 12 53 38 pm +screen shot 2017-08-08 at 12 53 25 pm + +#### Windows command prompt notes + +##### CMD + +On Windows the environment variable is set using the `set` command. + +```cmd +set DEBUG=*,-not_this +``` + +Example: + +```cmd +set DEBUG=* & node app.js +``` + +##### PowerShell (VS Code default) + +PowerShell uses different syntax to set environment variables. + +```cmd +$env:DEBUG = "*,-not_this" +``` + +Example: + +```cmd +$env:DEBUG='app';node app.js +``` + +Then, run the program to be debugged as usual. + +npm script example: +```js + "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js", +``` + +## Namespace Colors + +Every debug instance has a color generated for it based on its namespace name. +This helps when visually parsing the debug output to identify which debug instance +a debug line belongs to. + +#### Node.js + +In Node.js, colors are enabled when stderr is a TTY. You also _should_ install +the [`supports-color`](https://npmjs.org/supports-color) module alongside debug, +otherwise debug will only use a small handful of basic colors. + + + +#### Web Browser + +Colors are also enabled on "Web Inspectors" that understand the `%c` formatting +option. These are WebKit web inspectors, Firefox ([since version +31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) +and the Firebug plugin for Firefox (any version). + + + + +## Millisecond diff + +When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. + + + +When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below: + + + + +## Conventions + +If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output. + +## Wildcards + +The `*` character may be used as a wildcard. Suppose for example your library has +debuggers named "connect:bodyParser", "connect:compress", "connect:session", +instead of listing all three with +`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do +`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. + +You can also exclude specific debuggers by prefixing them with a "-" character. +For example, `DEBUG=*,-connect:*` would include all debuggers except those +starting with "connect:". + +## Environment Variables + +When running through Node.js, you can set a few environment variables that will +change the behavior of the debug logging: + +| Name | Purpose | +|-----------|-------------------------------------------------| +| `DEBUG` | Enables/disables specific debugging namespaces. | +| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). | +| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | +| `DEBUG_DEPTH` | Object inspection depth. | +| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | + + +__Note:__ The environment variables beginning with `DEBUG_` end up being +converted into an Options object that gets used with `%o`/`%O` formatters. +See the Node.js documentation for +[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) +for the complete list. + +## Formatters + +Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. +Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + + +### Custom formatters + +You can add custom formatters by extending the `debug.formatters` object. +For example, if you wanted to add support for rendering a Buffer as hex with +`%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + + +## Browser Support + +You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), +or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), +if you don't want to build it yourself. + +Debug's enable state is currently persisted by `localStorage`. +Consider the situation shown below where you have `worker:a` and `worker:b`, +and wish to debug both. You can enable this using `localStorage.debug`: + +```js +localStorage.debug = 'worker:*' +``` + +And then refresh the page. + +```js +a = debug('worker:a'); +b = debug('worker:b'); + +setInterval(function(){ + a('doing some work'); +}, 1000); + +setInterval(function(){ + b('doing some work'); +}, 1200); +``` + +In Chromium-based web browsers (e.g. Brave, Chrome, and Electron), the JavaScript console will—by default—only show messages logged by `debug` if the "Verbose" log level is _enabled_. + + + +## Output streams + + By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: + +Example [_stdout.js_](./examples/node/stdout.js): + +```js +var debug = require('debug'); +var error = debug('app:error'); + +// by default stderr is used +error('goes to stderr!'); + +var log = debug('app:log'); +// set this namespace to log via console.log +log.log = console.log.bind(console); // don't forget to bind to console! +log('goes to stdout'); +error('still goes to stderr!'); + +// set all output to go via console.info +// overrides all per-namespace log settings +debug.log = console.info.bind(console); +error('now goes to stdout via console.info'); +log('still goes to stdout, but via console.info now'); +``` + +## Extend +You can simply extend debugger +```js +const log = require('debug')('auth'); + +//creates new debug instance with extended namespace +const logSign = log.extend('sign'); +const logLogin = log.extend('login'); + +log('hello'); // auth hello +logSign('hello'); //auth:sign hello +logLogin('hello'); //auth:login hello +``` + +## Set dynamically + +You can also enable debug dynamically by calling the `enable()` method : + +```js +let debug = require('debug'); + +console.log(1, debug.enabled('test')); + +debug.enable('test'); +console.log(2, debug.enabled('test')); + +debug.disable(); +console.log(3, debug.enabled('test')); + +``` + +print : +``` +1 false +2 true +3 false +``` + +Usage : +`enable(namespaces)` +`namespaces` can include modes separated by a colon and wildcards. + +Note that calling `enable()` completely overrides previously set DEBUG variable : + +``` +$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))' +=> false +``` + +`disable()` + +Will disable all namespaces. The functions returns the namespaces currently +enabled (and skipped). This can be useful if you want to disable debugging +temporarily without knowing what was enabled to begin with. + +For example: + +```js +let debug = require('debug'); +debug.enable('foo:*,-foo:bar'); +let namespaces = debug.disable(); +debug.enable(namespaces); +``` + +Note: There is no guarantee that the string will be identical to the initial +enable string, but semantically they will be identical. + +## Checking whether a debug target is enabled + +After you've created a debug instance, you can determine whether or not it is +enabled by checking the `enabled` property: + +```javascript +const debug = require('debug')('http'); + +if (debug.enabled) { + // do stuff... +} +``` + +You can also manually toggle this property to force the debug instance to be +enabled or disabled. + +## Usage in child processes + +Due to the way `debug` detects if the output is a TTY or not, colors are not shown in child processes when `stderr` is piped. A solution is to pass the `DEBUG_COLORS=1` environment variable to the child process. +For example: + +```javascript +worker = fork(WORKER_WRAP_PATH, [workerPath], { + stdio: [ + /* stdin: */ 0, + /* stdout: */ 'pipe', + /* stderr: */ 'pipe', + 'ipc', + ], + env: Object.assign({}, process.env, { + DEBUG_COLORS: 1 // without this settings, colors won't be shown + }), +}); + +worker.stderr.pipe(process.stderr, { end: false }); +``` + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + - Josh Junon + +## Backers + +Support us with a monthly donation and help us continue our activities.

The general flow for each patch index is: + + - `options.loadFile(index, callback)` is called. The caller should then load the contents of the file and then pass that to the `callback(err, data)` callback. Passing an `err` will terminate further patch execution. + - `options.patched(index, content, callback)` is called once the patch has been applied. `content` will be the return value from `applyPatch`. When it's ready, the caller should call `callback(err)` callback. Passing an `err` will terminate further patch execution. + + Once all patches have been applied or an error occurs, the `options.complete(err)` callback is made. + +* `Diff.parsePatch(diffStr)` - Parses a patch into structured data + + Return a JSON object representation of the a patch, suitable for use with the `applyPatch` method. This parses to the same structure returned by `Diff.structuredPatch`. + +* `convertChangesToXML(changes)` - converts a list of changes to a serialized XML format + + +All methods above which accept the optional `callback` method will run in sync mode when that parameter is omitted and in async mode when supplied. This allows for larger diffs without blocking the event loop. This may be passed either directly as the final parameter or as the `callback` field in the `options` object. + +### Change Objects +Many of the methods above return change objects. These objects consist of the following fields: + +* `value`: Text content +* `added`: True if the value was inserted into the new string +* `removed`: True if the value was removed from the old string + +Note that some cases may omit a particular flag field.

+## Compatibility
+
+[![Sauce Test Status](https://saucelabs.com/browser-matrix/jsdiff.svg)](https://saucelabs.com/u/jsdiff)
+
+jsdiff supports all ES3 environments with some known issues on IE8 and below. Under these browsers some diff algorithms such as word diff and others may fail due to lack of support for capturing groups in the `split` operation.

+# extend() for Node.js [![Version Badge][npm-version-png]][npm-url]
+
+`node-extend` is a port of the classic extend() method from jQuery. It behaves as you expect. It is simple, tried and true.
+
+Notes:
+
+* Since Node.js >= 4,
+  [`Object.assign`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign)
+  now offers the same functionality natively (but without the "deep copy" option).
+  See [ECMAScript 2015 (ES6) in Node.js](https://nodejs.org/en/docs/es6).
+* Some native implementations of `Object.assign` in both Node.js and many
+  browsers (since NPM modules are for the browser too) may not be fully
+  spec-compliant.
+  Check [`object.assign`](https://www.npmjs.com/package/object.assign) module for
+  a compliant candidate.
+
+## Installation
+
+This package is available on [npm][npm-url] as: `extend`
+
+``` sh
+npm install extend
+```
+
+## Usage
+
+**Syntax:** extend **(** [`deep`], `target`, `object1`, [`objectN`] **)**
+
+*Extend one object with one or more others, returning the modified object.*
+
+**Example:**
+
+``` js
+var extend = require('extend');
+extend(targetObject, object1, object2);
+```
+
+Keep in mind that the target object will be modified, and will be returned from extend().
+
+If a boolean true is specified as the first argument, extend performs a deep copy, recursively copying any objects it finds. Otherwise, the copy will share structure with the original object(s).
+Undefined properties are not copied. However, properties inherited from the object's prototype will be copied over.
+Warning: passing `false` as the first argument is not supported.
+
+### Arguments
+
+* `deep` *Boolean* (optional)
+If set, the merge becomes recursive (i.e. deep copy).
+* `target`	*Object*
+The object to extend.
+* `object1`	*Object*
+The object that will be merged into the first.
+* `objectN` *Object* (Optional)
+More objects to merge into the first.

+# fs.realpath
+
+A backwards-compatible fs.realpath for Node v6 and above
+
+In Node v6, the JavaScript implementation of fs.realpath was replaced
+with a faster (but less resilient) native implementation.  That raises
+new and platform-specific errors and cannot handle long or excessively
+symlink-looping paths.
+
+This module handles those cases by detecting the new errors and
+falling back to the JavaScript implementation.  On versions of Node
+prior to v6, it has no effect.
+
+## USAGE
+
+```js
+var rp = require('fs.realpath')
+
+// async version
+rp.realpath(someLongAndLoopingPath, function (er, real) {
+  // the ELOOP was handled, but it was a bit slower
+})
+
+// sync version
+var real = rp.realpathSync(someLongAndLoopingPath)
+
+// monkeypatch at your own risk!
+// This replaces the fs.realpath/fs.realpathSync builtins
+rp.monkeypatch()
+
+// un-do the monkeypatching
+rp.unmonkeypatch()
+```

+# Glob
+
+Match files using the patterns the shell uses, like stars and stuff.
+
+[![Build Status](https://travis-ci.org/isaacs/node-glob.svg?branch=master)](https://travis-ci.org/isaacs/node-glob/) [![Build Status](https://ci.appveyor.com/api/projects/status/kd7f3yftf7unxlsx?svg=true)](https://ci.appveyor.com/project/isaacs/node-glob) [![Coverage Status](https://coveralls.io/repos/isaacs/node-glob/badge.svg?branch=master&service=github)](https://coveralls.io/github/isaacs/node-glob?branch=master)
+
+This is a glob implementation in JavaScript.  It uses the `minimatch`
+library to do its matching.
+
+![a fun cartoon logo made of glob characters](logo/glob.png)
+
+## Usage
+
+Install with npm
+
+```
+npm i glob
+```
+
+```javascript
+var glob = require("glob")
+
+// options is optional
+glob("**/*.js", options, function (er, files) {
+  // files is an array of filenames.
+  // If the `nonull` option is set, and nothing
+  // was found, then files is ["**/*.js"]
+  // er is an error object or null.
+})
+```
+
+## Glob Primer
+
+"Globs" are the patterns you type when you do stuff like `ls *.js` on
+the command line, or put `build/*` in a `.gitignore` file.
+
+Before parsing the path part patterns, braced sections are expanded
+into a set.  Braced sections start with `{` and end with `}`, with any
+number of comma-delimited sections within.  Braced sections may contain
+slash characters, so `a{/b/c,bcd}` would expand into `a/b/c` and `abcd`.
+
+The following characters have special magic meaning when used in a
+path portion:
+
+* `*` Matches 0 or more characters in a single path portion
+* `?` Matches 1 character
+* `[...]` Matches a range of characters, similar to a RegExp range.
+  If the first character of the range is `!` or `^` then it matches
+  any character not in the range.
+* `!(pattern|pattern|pattern)` Matches anything that does not match
+  any of the patterns provided.
+* `?(pattern|pattern|pattern)` Matches zero or one occurrence of the
+  patterns provided.
+* `+(pattern|pattern|pattern)` Matches one or more occurrences of the
+  patterns provided.
+* `*(a|b|c)` Matches zero or more occurrences of the patterns provided
+* `@(pattern|pat*|pat?erN)` Matches exactly one of the patterns
+  provided
+* `**` If a "globstar" is alone in a path portion, then it matches
+  zero or more directories and subdirectories searching for matches.
+  It does not crawl symlinked directories.
+
+### Dots
+
+If a file or directory path portion has a `.` as the first character,
+then it will not match any glob pattern unless that pattern's
+corresponding path part also has a `.` as its first character.
+
+For example, the pattern `a/.*/c` would match the file at `a/.b/c`.
+However the pattern `a/*/c` would not, because `*` does not start with
+a dot character.
+
+You can make glob treat dots as normal characters by setting
+`dot:true` in the options.
+
+### Basename Matching
+
+If you set `matchBase:true` in the options, and the pattern has no
+slashes in it, then it will seek for any file anywhere in the tree
+with a matching basename.  For example, `*.js` would match
+`test/simple/basic.js`.
+
+### Empty Sets
+
+If no matching files are found, then an empty array is returned.  This
+differs from the shell, where the pattern itself is returned.  For
+example:
+
+    $ echo a*s*d*f
+    a*s*d*f
+
+To get the bash-style behavior, set the `nonull:true` in the options.
+
+### See Also:
+
+* `man sh`
+* `man bash` (Search for "Pattern Matching")
+* `man 3 fnmatch`
+* `man 5 gitignore`
+* [minimatch documentation](https://github.com/isaacs/minimatch)
+
+## glob.hasMagic(pattern, [options])
+
+Returns `true` if there are any special characters in the pattern, and
+`false` otherwise.
+
+Note that the options affect the results.  If `noext:true` is set in
+the options object, then `+(a|b)` will not be considered a magic
+pattern.  If the pattern has a brace expansion, like `a/{b/c,x/y}`
+then that is considered magical, unless `nobrace:true` is set in the
+options.
+
+## glob(pattern, [options], cb)
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* `cb` `{Function}`
+  * `err` `{Error | null}`
+  * `matches` `{Array}` filenames found matching the pattern
+
+Perform an asynchronous glob search.
+
+## glob.sync(pattern, [options])
+
+* `pattern` `{String}` Pattern to be matched
+* `options` `{Object}`
+* return: `{Array}` filenames found matching the pattern
+
+Perform a synchronous glob search.
+
+## Class: glob.Glob
+
+Create a Glob object by instantiating the `glob.Glob` class.
+
+```javascript
+var Glob = require("glob").Glob
+var mg = new Glob(pattern, options, cb)
+```
+
+It's an EventEmitter, and starts walking the filesystem to find matches
+immediately.
+
+### new glob.Glob(pattern, [options], [cb])
+
+* `pattern` `{String}` pattern to search for
+* `options` `{Object}`
+* `cb` `{Function}` Called when an error occurs, or matches are found
+  * `err` `{Error | null}`
+  * `matches` `{Array}` filenames found matching the pattern
+
+Note that if the `sync` flag is set in the options, then matches will
+be immediately available on the `g.found` member.
+
+### Properties
+
+* `minimatch` The minimatch object that the glob uses.
+* `options` The options object passed in.
+* `aborted` Boolean which is set to true when calling `abort()`.  There
+  is no way at this time to continue a glob search after aborting, but
+  you can re-use the statCache to avoid having to duplicate syscalls.
+* `cache` Convenience object.  Each field has the following possible
+  values:
+  * `false` - Path does not exist
+  * `true` - Path exists
+  * `'FILE'` - Path exists, and is not a directory
+  * `'DIR'` - Path exists, and is a directory
+  * `[file, entries, ...]` - Path exists, is a directory, and the
+    array value is the results of `fs.readdir`
+* `statCache` Cache of `fs.stat` results, to prevent statting the same
+  path multiple times.
+* `symlinks` A record of which paths are symbolic links, which is
+  relevant in resolving `**` patterns.
+* `realpathCache` An optional object which is passed to `fs.realpath`
+  to minimize unnecessary syscalls.  It is stored on the instantiated
+  Glob object, and may be re-used.
+
+### Events
+
+* `end` When the matching is finished, this is emitted with all the
+  matches found.  If the `nonull` option is set, and no match was found,
+  then the `matches` list contains the original pattern.  The matches
+  are sorted, unless the `nosort` flag is set.
+* `match` Every time a match is found, this is emitted with the specific
+  thing that matched. It is not deduplicated or resolved to a realpath.
+* `error` Emitted when an unexpected error is encountered, or whenever
+  any fs error occurs if `options.strict` is set.
+* `abort` When `abort()` is called, this event is raised.
+
+### Methods
+
+* `pause` Temporarily stop the search
+* `resume` Resume the search
+* `abort` Stop the search forever
+
+### Options
+
+All the options that can be passed to Minimatch can also be passed to
+Glob to change pattern matching behavior.  Also, some have been added,
+or have glob-specific ramifications.
+
+All options are false by default, unless otherwise noted.
+
+All options are added to the Glob object, as well.
+
+If you are running many `glob` operations, you can pass a Glob object
+as the `options` argument to a subsequent operation to shortcut some
+`stat` and `readdir` calls.  At the very least, you may pass in shared
+`symlinks`, `statCache`, `realpathCache`, and `cache` options, so that
+parallel glob operations will be sped up by sharing information about
+the filesystem.
+
+* `cwd` The current working directory in which to search.  Defaults
+  to `process.cwd()`.
+* `root` The place where patterns starting with `/` will be mounted
+  onto.  Defaults to `path.resolve(options.cwd, "/")` (`/` on Unix
+  systems, and `C:\` or some such on Windows.)
+* `dot` Include `.dot` files in normal matches and `globstar` matches.
+  Note that an explicit dot in a portion of the pattern will always
+  match dot files.
+* `nomount` By default, a pattern starting with a forward-slash will be
+  "mounted" onto the root setting, so that a valid filesystem path is
+  returned.  Set this flag to disable that behavior.
+* `mark` Add a `/` character to directory matches.  Note that this
+  requires additional stat calls.
+* `nosort` Don't sort the results.
+* `stat` Set to true to stat *all* results.  This reduces performance
+  somewhat, and is completely unnecessary, unless `readdir` is presumed
+  to be an untrustworthy indicator of file existence.
+* `silent` When an unusual error is encountered when attempting to
+  read a directory, a warning will be printed to stderr.  Set the
+  `silent` option to true to suppress these warnings.
+* `strict` When an unusual error is encountered when attempting to
+  read a directory, the process will just continue on in search of
+  other matches.  Set the `strict` option to raise an error in these
+  cases.
+* `cache` See `cache` property above.  Pass in a previously generated
+  cache object to save some fs calls.
+* `statCache` A cache of results of filesystem information, to prevent
+  unnecessary stat calls.  While it should not normally be necessary
+  to set this, you may pass the statCache from one glob() call to the
+  options object of another, if you know that the filesystem will not
+  change between calls.  (See "Race Conditions" below.)
+* `symlinks` A cache of known symbolic links.  You may pass in a
+  previously generated `symlinks` object to save `lstat` calls when
+  resolving `**` matches.
+* `sync` DEPRECATED: use `glob.sync(pattern, opts)` instead.
+* `nounique` In some cases, brace-expanded patterns can result in the
+  same file showing up multiple times in the result set.  By default,
+  this implementation prevents duplicates in the result set.  Set this
+  flag to disable that behavior.
+* `nonull` Set to never return an empty set, instead returning a set
+  containing the pattern itself.  This is the default in glob(3).
+* `debug` Set to enable debug logging in minimatch and glob.
+* `nobrace` Do not expand `{a,b}` and `{1..3}` brace sets.
+* `noglobstar` Do not match `**` against multiple filenames.  (Ie,
+  treat it as a normal `*` instead.)
+* `noext` Do not match `+(a|b)` "extglob" patterns.
+* `nocase` Perform a case-insensitive match.  Note: on
+  case-insensitive filesystems, non-magic patterns will match by
+  default, since `stat` and `readdir` will not raise errors.
+* `matchBase` Perform a basename-only match if the pattern does not
+  contain any slash characters.  That is, `*.js` would be treated as
+  equivalent to `**/*.js`, matching all js files in all directories.
+* `nodir` Do not match directories, only files.  (Note: to match
+  *only* directories, simply put a `/` at the end of the pattern.)
+* `ignore` Add a pattern or an array of glob patterns to exclude matches.
+  Note: `ignore` patterns are *always* in `dot:true` mode, regardless
+  of any other settings.
+* `follow` Follow symlinked directories when expanding `**` patterns.
+  Note that this can result in a lot of duplicate references in the
+  presence of cyclic links.
+* `realpath` Set to true to call `fs.realpath` on all of the results.
+  In the case of a symlink that cannot be resolved, the full absolute
+  path to the matched entry is returned (though it will usually be a
+  broken symlink)
+* `absolute` Set to true to always receive absolute paths for matched
+  files.  Unlike `realpath`, this also affects the values returned in
+  the `match` event.
+* `fs` File-system object with Node's `fs` API. By default, the built-in
+  `fs` module will be used. Set to a volume provided by a library like
+  `memfs` to avoid using the "real" file-system.
+
+## Comparisons to other fnmatch/glob implementations
+
+While strict compliance with the existing standards is a worthwhile
+goal, some discrepancies exist between node-glob and other
+implementations, and are intentional.
+
+The double-star character `**` is supported by default, unless the
+`noglobstar` flag is set.  This is supported in the manner of bsdglob
+and bash 4.3, where `**` only has special significance if it is the only
+thing in a path part.  That is, `a/**/b` will match `a/x/y/b`, but
+`a/**b` will not.
+
+Note that symlinked directories are not crawled as part of a `**`,
+though their contents may match against subsequent portions of the
+pattern.  This prevents infinite loops and duplicates and the like.
+
+If an escaped pattern has no matches, and the `nonull` flag is set,
+then glob returns the pattern as-provided, rather than
+interpreting the character escapes.  For example,
+`glob.match([], "\\*a\\?")` will return `"\\*a\\?"` rather than
+`"*a?"`.  This is akin to setting the `nullglob` option in bash, except
+that it does not resolve escaped pattern characters.
+
+If brace expansion is not disabled, then it is performed before any
+other interpretation of the glob pattern.  Thus, a pattern like
+`+(a|{b),c)}`, which would not be valid in bash or zsh, is expanded
+**first** into the set of `+(a|b)` and `+(a|c)`, and those patterns are
+checked for validity.  Since those two are valid, matching proceeds.
+
+### Comments and Negation
+
+Previously, this module let you mark a pattern as a "comment" if it
+started with a `#` character, or a "negated" pattern if it started
+with a `!` character.
+
+These options were deprecated in version 5, and removed in version 6.
+
+To specify things that should not match, use the `ignore` option.
+
+## Windows
+
+**Please only use forward-slashes in glob expressions.**
+
+Though windows uses either `/` or `\` as its path separator, only `/`
+characters are used by this glob implementation.  You must use
+forward-slashes **only** in glob expressions.  Back-slashes will always
+be interpreted as escape characters, not path separators.
+
+Results from absolute patterns such as `/foo/*` are mounted onto the
+root setting using `path.join`.  On windows, this will by default result
+in `/foo/*` matching `C:\foo\bar.txt`.
+
+## Race Conditions
+
+Glob searching, by its very nature, is susceptible to race conditions,
+since it relies on directory walking and such.
+
+As a result, it is possible that a file that exists when glob looks for
+it may have been deleted or modified by the time it returns the result.
+
+As part of its internal implementation, this program caches all stat
+and readdir calls that it makes, in order to cut down on system
+overhead.  However, this also makes it even more susceptible to races,
+especially if the cache or statCache objects are reused between glob
+calls.
+
+Users are thus advised not to use a glob result as a guarantee of
+filesystem state in the face of rapid changes.  For the vast majority
+of operations, this is never a problem.

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+#### Determine if an object is a [`Buffer`](http://nodejs.org/api/buffer.html) (including the [browserify Buffer](https://github.com/feross/buffer))

+
+## Why not use `Buffer.isBuffer`?
+
+This module lets you check if an object is a `Buffer` without using `Buffer.isBuffer` (which includes the whole [buffer](https://github.com/feross/buffer) module in [browserify](http://browserify.org/)).
+
+It's future-proof and works in node too!
+
+## install
+
+```bash
+npm install is-buffer
+```
+
+## usage
+
+```js
+var isBuffer = require('is-buffer')
+
+isBuffer(new Buffer(4)) // true
+isBuffer(Buffer.alloc(4)) //true
+
+isBuffer(undefined) // false
+isBuffer(null) // false
+isBuffer('') // false
+isBuffer(true) // false
+isBuffer(false) // false
+isBuffer(0) // false
+isBuffer(1) // false
+isBuffer(1.0) // false
+isBuffer('string') // false
+isBuffer({}) // false
+isBuffer(function foo () {}) // false

+# isexe
+
+Minimal module to check if a file is executable, and a normal file.
+
+Uses `fs.stat` and tests against the `PATHEXT` environment variable on
+Windows.
+
+## USAGE
+
+```javascript
+var isexe = require('isexe')
+isexe('some-file-name', function (err, isExe) {
+  if (err) {
+    console.error('probably file does not exist or something', err)
+  } else if (isExe) {
+    console.error('this thing can be run')
+  } else {
+    console.error('cannot be run')
+  }
+})
+
+// same thing but synchronous, throws errors
+var isExe = isexe.sync('some-file-name')
+
+// treat errors as just "not executable"
+isexe('maybe-missing-file', { ignoreErrors: true }, callback)
+var isExe = isexe.sync('maybe-missing-file', { ignoreErrors: true })
+```
+
+## API
+
+### `isexe(path, [options], [callback])`
+
+Check if the path is executable.  If no callback provided, and a
+global `Promise` object is available, then a Promise will be returned.
+
+Will raise whatever errors may be raised by `fs.stat`, unless
+`options.ignoreErrors` is set to true.
+
+### `isexe.sync(path, [options])`
+
+Same as `isexe` but returns the value and throws any errors raised.
+
+### Options
+
+* `ignoreErrors` Treat all errors as "no, this is not executable", but
+  don't raise them.
+* `uid` Number to use as the user id
+* `gid` Number to use as the group id
+* `pathExt` List of path extensions to use instead of `PATHEXT`
+  environment variable on Windows.

+  kleur
+

+
+
+
+
The fastest Node.js library for formatting terminal text with ANSI colors~!

+
+## Features
+
+* No dependencies
+* Super [lightweight](#load-time) & [performant](#performance)
+* Supports [nested](#nested-methods) & [chained](#chained-methods) colors
+* No `String.prototype` modifications
+* Conditional [color support](#conditional-support)
+* [Fully treeshakable](#individual-colors)
+* Familiar [API](#api)
+
+---
+
+As of `v3.0` the Chalk-style syntax (magical getter) is no longer used.
Please visit [History](#history) for migration paths supporting that syntax.
+
+---
+
+
+## Install
+
+```
+$ npm install --save kleur
+```
+
+
+## Usage
+
+```js
+import kleur from 'kleur';
+
+// basic usage
+kleur.red('red text');
+
+// chained methods
+kleur.blue().bold().underline('howdy partner');
+
+// nested methods
+kleur.bold(`${ white().bgRed('[ERROR]') } ${ kleur.red().italic('Something happened')}`);
+```
+
+### Chained Methods
+
+```js
+const { bold, green } = require('kleur');
+
+console.log(bold().red('this is a bold red message'));
+console.log(bold().italic('this is a bold italicized message'));
+console.log(bold().yellow().bgRed().italic('this is a bold yellow italicized message'));
+console.log(green().bold().underline('this is a bold green underlined message'));
+```
+
+
+
+### Nested Methods
+
+```js
+const { yellow, red, cyan } = require('kleur');
+
+console.log(yellow(`foo ${red().bold('red')} bar ${cyan('cyan')} baz`));
+console.log(yellow('foo ' + red().bold('red') + ' bar ' + cyan('cyan') + ' baz'));
+```
+
+
+
+
+### Conditional Support
+
+Toggle color support as needed; `kleur` includes simple auto-detection which may not cover all cases.
+
+> **Note:** Both `kleur` and `kleur/colors` share the same detection logic.
+
+```js
+import kleur from 'kleur';
+
+// manually disable
+kleur.enabled = false;
+
+// or use another library to detect support
+kleur.enabled = require('color-support').level > 0;
+
+console.log(kleur.red('I will only be colored red if the terminal supports colors'));
+```
+
+> **Important:** 
Colors will be disabled automatically in non [TTY contexts](https://nodejs.org/api/process.html#process_a_note_on_process_i_o). For example, spawning another process or piping output into another process will disable colorization automatically. To force colors in your piped output, you may do so with the `FORCE_COLOR=1` environment variable:
+
+```sh
+$ node app.js #=> COLORS
+$ node app.js > log.txt  #=> NO COLORS
+$ FORCE_COLOR=1 node app.js > log.txt #=> COLORS
+$ FORCE_COLOR=0 node app.js > log.txt #=> NO COLORS
+```
+
+## API
+
+Any `kleur` method returns a `String` when invoked with input; otherwise chaining is expected.
+
+> It's up to the developer to pass the output to destinations like `console.log`, `process.stdout.write`, etc.
+
+The methods below are grouped by type for legibility purposes only. They each can be [chained](#chained-methods) or [nested](#nested-methods) with one another.
+
+***Colors:***
+> black — red — green — yellow — blue — magenta — cyan — white — gray — grey
+
+***Backgrounds:***
+> bgBlack — bgRed — bgGreen — bgYellow — bgBlue — bgMagenta — bgCyan — bgWhite
+
+***Modifiers:***
+> reset — bold — dim — italic* — underline — inverse — hidden — strikethrough*
+
+* Not widely supported
+
+
+## Individual Colors
+
+When you only need a few colors, it doesn't make sense to import _all_ of `kleur` because, as small as it is, `kleur` is not treeshakeable, and so most of its code will be doing nothing. In order to fix this, you can import from the `kleur/colors` submodule which _fully_ supports tree-shaking.
+
+The caveat with this approach is that color functions **are not** chainable~!
Each function receives and colorizes its input. You may combine colors, backgrounds, and modifiers by nesting function calls within other functions.
+
+```js
+// or: import * as kleur from 'kleur/colors';
+import { red, underline, bgWhite } from 'kleur/colors';
+
+red('red text');
+//~> kleur.red('red text');
+
+underline(red('red underlined text'));
+//~> kleur.underline().red('red underlined text');
+
+bgWhite(underline(red('red underlined text w/ white background')));
+//~> kleur.bgWhite().underline().red('red underlined text w/ white background');
+```
+
+> **Note:** All the same [colors, backgrounds, and modifiers](#api) are available.
+
+***Conditional Support***
+
+The `kleur/colors` submodule also allows you to toggle color support, as needed.

+It includes the same initial assumptions as `kleur`, in an attempt to have colors enabled by default.
+
+Unlike `kleur`, this setting exists as `kleur.$.enabled` instead of `kleur.enabled`:
+
+```js
+import * as kleur from 'kleur/colors';
+// or: import { $, red } from 'kleur/colors';
+
+// manually disabled
+kleur.$.enabled = false;
+
+// or use another library to detect support
+kleur.$.enabled = require('color-support').level > 0;
+
+console.log(red('I will only be colored red if the terminal supports colors'));
+```
+
+

+```
+
+
+## History
+
+This project originally forked [`ansi-colors`](https://github.com/doowb/ansi-colors).
+
+Beginning with `kleur@3.0`, the Chalk-style syntax (magical getter) has been replaced with function calls per key:
+
+```js
+// Old:
+c.red.bold.underline('old');
+
+// New:
+c.red().bold().underline('new');
+```
+> As I work more with Rust, the newer syntax feels so much better & more natural!
+
+If you prefer the old syntax, you may migrate to `ansi-colors` or newer `chalk` releases.
Versions below `kleur@3.0` have been officially deprecated.

+
+## What is this?
+
+This is a tiny package that finds the count of the longest adjacent repeating
+substring.
+
+## When should I use this?
+
+This package is rather niche.
+I use it for serializing markdown ASTs (particularly fenced code and math).
+
+You can use [`ccount`][ccount] if you need the total count of substrings
+occuring in a value.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 14.14+, 16.0+), install with [npm][]:
+
+```sh
+npm install longest-streak
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {longestStreak} from 'https://esm.sh/longest-streak@3'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import {longestStreak} from 'longest-streak'
+
+longestStreak('` foo `` bar `', '`') // => 2
+```
+
+## API
+
+This package exports the identifier `longestStreak`.
+There is no default export.
+
+### `longestStreak(value, substring)`
+
+Get the count of the longest repeating streak of `substring` in `value`.
+
+###### Parameters
+
+*   `value` (`string`) — content to search in
+*   `substring` (`string`) — substring to look for, typically one character
+
+###### Returns
+
+Count of most frequent adjacent `substring`s in `value` (`number`).
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports no additional types.
+
+## Compatibility
+
+This package is at least compatible with all maintained versions of Node.js.
+As of now, that is Node.js 14.14+ and 16.0+.
+It also works in Deno and modern browsers.
+
+## Security
+
+This package is safe.
+
+## Related
+
+*   [`wooorm/ccount`](https://github.com/wooorm/ccount)
+    — count the total number of `substring`s in `value`
+*   [`wooorm/direction`](https://github.com/wooorm/direction)
+    — detect directionality: left-to-right, right-to-left, or neutral

+
+## What is this?
+
+This package is a utility that takes markdown input and turns it into an
+[mdast][] syntax tree.
+
+This utility uses [`micromark`][micromark], which turns markdown into tokens,
+and then turns those tokens into nodes.
+This package is used inside [`remark-parse`][remark-parse], which focusses on
+making it easier to transform content by abstracting these internals away.
+
+## When should I use this?
+
+If you want to handle syntax trees manually, use this.
+When you *just* want to turn markdown into HTML, use [`micromark`][micromark]
+instead.
+For an easier time processing content, use the **[remark][]** ecosystem instead.
+
+You can combine this package with other packages to add syntax extensions to
+markdown.
+Notable examples that deeply integrate with this package are
+[`mdast-util-gfm`][mdast-util-gfm],
+[`mdast-util-mdx`][mdast-util-mdx],
+[`mdast-util-frontmatter`][mdast-util-frontmatter],
+[`mdast-util-math`][mdast-util-math], and
+[`mdast-util-directive`][mdast-util-directive].
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 14.14+ and 16.0+), install with [npm][]:
+
+```sh
+npm install mdast-util-from-markdown
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {fromMarkdown} from 'https://esm.sh/mdast-util-from-markdown@1'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+Say we have the following markdown file `example.md`:
+
+```markdown
+## Hello, *World*!
+```
+
+…and our module `example.js` looks as follows:
+
+```js
+import fs from 'node:fs/promises'
+import {fromMarkdown} from 'mdast-util-from-markdown'
+
+const doc = await fs.readFile('example.md')
+const tree = fromMarkdown(doc)
+
+console.log(tree)
+```
+
+…now running `node example.js` yields (positional info removed for brevity):
+
+```js
+{
+  type: 'root',
+  children: [
+    {
+      type: 'heading',
+      depth: 2,
+      children: [
+        {type: 'text', value: 'Hello, '},
+        {type: 'emphasis', children: [{type: 'text', value: 'World'}]},
+        {type: 'text', value: '!'}
+      ]
+    }
+  ]
+}
+```
+
+## API
+
+This package exports the identifier [`fromMarkdown`][api-frommarkdown].
+There is no default export.
+
+The export map supports the [`development` condition][development].
+Run `node --conditions development example.js` to get instrumented dev code.
+Without this condition, production code is loaded.
+

+interface to register their types:
+
+```ts
+declare module 'mdast-util-from-markdown' {
+  interface CompileData {
+    // Register a new field.
+    mathFlowInside?: boolean | undefined

+
+## Syntax
+
+Markdown is parsed according to CommonMark.
+Extensions can add support for other syntax.
+If you’re interested in extending markdown,
+[more information is available in micromark’s readme][micromark-extend].
+
+## Syntax tree
+
+The syntax tree is [mdast][].
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports the additional types [`CompileContext`][api-compilecontext],
+[`CompileData`][api-compiledata],
+[`Encoding`][api-encoding],
+[`Extension`][api-extension],
+[`Handle`][api-handle],
+[`OnEnterError`][api-onentererror],
+[`OnExitError`][api-onexiterror],
+[`Options`][api-options],
+[`Token`][api-token],
+[`Transform`][api-transform], and
+[`Value`][api-value].
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with all maintained
+versions of Node.js.
+As of now, that is Node.js 14.14+ and 16.0+.
+Our projects sometimes work with older versions, but this is not guaranteed.
+
+## Security
+
+As markdown is sometimes used for HTML, and improper use of HTML can open you up
+to a [cross-site scripting (XSS)][xss] attack, use of `mdast-util-from-markdown`
+can also be unsafe.
+When going to HTML, use this utility in combination with
+[`hast-util-sanitize`][hast-util-sanitize] to make the tree safe.

+
+## What is this?
+
+This package is a tiny utility to check that a given [node][] is [phrasing
+content][phrasing].
+
+## When should I use this?
+
+This utility is typically useful if you’re making other utilities.
+It uses [`unist-util-is`][unist-util-is], which you can use for your own checks.
+
+A different utility, [`hast-util-phrasing`][hast-util-phrasing], does the same
+but on [hast][].
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 14.14+ and 16.0+), install with [npm][]:
+
+```sh
+npm install mdast-util-phrasing
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {phrasing} from 'https://esm.sh/mdast-util-phrasing@3'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import {phrasing} from 'mdast-util-phrasing'
+
+phrasing({type: 'paragraph', children: [{type: 'text', value: 'Alpha'}]})
+// => false
+
+phrasing({type: 'strong', children: [{type: 'text', value: 'Delta'}]})
+// => true
+```
+
+## API
+
+This package exports the identifier [`phrasing`][api-phrasing].
+There is no default export.
+
+### `phrasing(value)`
+
+Check if the given value is *[phrasing content][phrasing]*.
+
+###### Parameters
+
+*   `value` (`unknown`)
+    — thing to check, typically [`Node`][node]
+
+###### Returns
+
+Whether `value` is phrasing content (`boolean`).
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It does not export extra types.
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with all maintained
+versions of Node.js.
+As of now, that is Node.js 14.14+ and 16.0+.
+Our projects sometimes work with older versions, but this is not guaranteed.
+
+## Security
+
+Use of `mdast-util-phrasing` does not involve **[hast][]**, user content, or
+change the tree, so there are no openings for [cross-site scripting (XSS)][xss]
+attacks.
+
+## Related
+
+*   [`hast-util-phrasing`](https://github.com/syntax-tree/hast-util-phrasing)
+    — check if a hast node is phrasing content
+*   [`unist-util-is`](https://github.com/syntax-tree/unist-util-is)
+    — check if a node passes a test

+ *   Parent of `node`.
+ * @param {State} state
+ *   Info passed around about the current state.

+ *
+ *   Each key is a node type, each value its corresponding handler.

+ * @callback Join
+ *   How to join two blocks.
+ *
+ *   “Blocks” are typically joined by one blank line.
+ *   Sometimes it’s nicer to have them flush next to each other, yet other

+ *
+ *   Join functions receive two adjacent siblings and their parent and what

+ * @param {Node} left
+ *   First of two adjacent siblings.
+ * @param {Node} right
+ *   Second of two adjacent siblings.
+ * @param {Parent} parent
+ *   Parent of the two siblings.
+ * @param {State} state
+ *   Info passed around about the current state.
+ * @returns {boolean | null | undefined | void | number}
+ *   How many blank lines to use between the siblings.
+ *
+ *   Where `true` is as passing `1` and `false` means the nodes cannot be
+ *   joined by a blank line, such as two adjacent block quotes or indented code
+ *   after a list, in which case a comment will be injected to break them up:
+ *
+ *   ```markdown
+ *   > Quote 1
+ *

+ *   > Quote 2
+ *   ```
+ *

+ *
+ * @typedef Unsafe
+ *   Schema that defines when a character cannot occur.
+ * @property {string} character
+ *   Single unsafe character.
+ * @property {ConstructName | Array | null | undefined} [inConstruct]
+ *   Constructs where this is bad.
+ * @property {ConstructName | Array | null | undefined} [notInConstruct]
+ *   Constructs where this is fine again.
+ * @property {string | null | undefined} [before]
+ *   `character` is bad when this is before it (cannot be used together with
+ *   `atBreak`).
+ * @property {string | null | undefined} [after]
+ *   `character` is bad when this is after it.
+ * @property {boolean | null | undefined} [atBreak]
+ *   `character` is bad at a break (cannot be used together with `before`).
+ * @property {RegExp | null | undefined} [_compiled]
+ *   The unsafe pattern (this whole object) compiled as a regex.
+ *
+ *   This is internal and must not be defined.
+ *
+ * @typedef Options
+ *   Configuration (optional).
+ * @property {'-' | '*' | '+' | null | undefined} [bullet='*']
+ *   Marker to use for bullets of items in unordered lists.
+ * @property {'-' | '*' | '+' | null | undefined} [bulletOther]
+ *   Marker to use in certain cases where the primary bullet doesn’t work.
+ *
+ *   There are three cases where the primary bullet cannot be used:
+ *
+ *   *   When three list items are on their own, the last one is empty, and
+ *       `bullet` is also a valid `rule`: `* - +`.
+ *       This would turn into a thematic break if serialized with three primary
+ *       bullets.
+ *       As this is an edge case unlikely to appear in normal markdown, the
+ *       last list item will be given a different bullet.
+ *   *   When a thematic break is the first child of one of the list items, and
+ *       `bullet` is the same character as `rule`: `- ***`.
+ *       This would turn into a single thematic break if serialized with
+ *       primary bullets.
+ *       As this is an edge case unlikely to appear in normal markdown this
+ *       markup is always fixed, even if `bulletOther` is not passed
+ *   *   When two unordered lists appear next to each other: `* a\n- b`.
+ *       CommonMark sees different bullets as different lists, but several
+ *       markdown parsers parse it as one list.
+ *       To solve for both, we instead inject an empty comment between the two
+ *       lists: `* a\n\n* b`, but if `bulletOther` is given explicitly,
+ *       it will be used instead
+ * @property {'.' | ')' | null | undefined} [bulletOrdered='.']
+ *   Marker to use for bullets of items in ordered lists.
+ * @property {'.' | ')' | null | undefined} [bulletOrderedOther]
+ *   Marker to use in certain cases where the primary bullet for ordered items
+ *   doesn’t work.
+ *
+ *   There is one case where the primary bullet for ordered items cannot be used:
+ *
+ *   *   When two ordered lists appear next to each other: `1. a\n2) b`.
+ *       CommonMark added support for `)` as a marker, but other markdown
+ *       parsers do not support it.
+ *       To solve for both, we instead inject an empty comment between the two
+ *       lists: `1. a\n\n1. b`, but if `bulletOrderedOther` is given
+ *       explicitly, it will be used instead
+ * @property {boolean | null | undefined} [closeAtx=false]
+ *   Whether to add the same number of number signs (`#`) at the end of an ATX
+ *   heading as the opening sequence.
+ * @property {'_' | '*' | null | undefined} [emphasis='*']
+ *   Marker to use for emphasis.
+ * @property {'~' | '`' | null | undefined} [fence='`']
+ *   Marker to use for fenced code.
+ * @property {boolean | null | undefined} [fences=false]
+ *   Whether to use fenced code always.
+ *
+ *   The default is to use fenced code if there is a language defined, if the
+ *   code is empty, or if it starts or ends in blank lines.
+ * @property {boolean | null | undefined} [incrementListMarker=true]
+ *   Whether to increment the counter of ordered lists items.
+ * @property {'tab' | 'one' | 'mixed' | null | undefined} [listItemIndent='tab']
+ *   How to indent the content of list items.
+ *
+ *   Either with the size of the bullet plus one space (when `'one'`), a tab
+ *   stop (`'tab'`), or depending on the item and its parent list (`'mixed'`,
+ *   uses `'one'` if the item and list are tight and `'tab'` otherwise).
+ * @property {'"' | "'" | null | undefined} [quote='"']
+ *   Marker to use for titles.
+ * @property {boolean | null | undefined} [resourceLink=false]
+ *   Whether to always use resource links.
+ *
+ *   The default is to use autolinks (``) when possible
+ *   and resource links (`[text](url)`) otherwise.
+ * @property {'-' | '_' | '*' | null | undefined} [rule='*']
+ *   Marker to use for thematic breaks.
+ * @property {number | null | undefined} [ruleRepetition=3]
+ *   Number of markers to use for thematic breaks.
+ * @property {boolean | null | undefined} [ruleSpaces=false]
+ *   Whether to add spaces between markers in thematic breaks.
+ * @property {boolean | null | undefined} [setext=false]
+ *   Whether to use setext headings when possible.
+ *
+ *   The default is to always use ATX headings (`# heading`) instead of setext
+ *   headings (`heading\n=======`).
+ *   Setext headings cannot be used for empty headings or headings with a rank
+ *   of three or more.
+ * @property {'_' | '*' | null | undefined} [strong='*']
+ *   Marker to use for strong.
+ * @property {boolean | null | undefined} [tightDefinitions=false]
+ *   Whether to join definitions without a blank line.
+ *
+ *   The default is to add blank lines between any flow (“block”) construct.
+ *   Turning this option on is a shortcut for a join function like so:
+ *
+ *   ```js
+ *   function joinTightDefinitions(left, right) {
+ *     if (left.type === 'definition' && right.type === 'definition') {
+ *       return 0
+ *     }
+ *   }
+ *   ```
+ * @property {Partial | null | undefined} [handlers={}]
+ *   Handle particular nodes.
+ *
+ *   Each key is a node type, each value its corresponding handler.
+ * @property {Array | null | undefined} [join=[]]
+ *   How to join blocks.
+ * @property {Array | null | undefined} [unsafe=[]]
+ *   Schemas that define when characters cannot occur.
+ * @property {Array | null | undefined} [extensions=[]]
+ *   List of extensions to include.
+ *
+ *   Each `ToMarkdownExtension` is an object with the same interface as
+ *   `Options` here.

+
+## What is this?
+
+This package is a utility that takes an [mdast][] syntax tree as input and turns
+it into serialized markdown.
+
+This utility is a low level project.
+It’s used in [`remark-stringify`][remark-stringify], which focusses on making it
+easier to transform content by abstracting these internals away.
+
+## When should I use this?
+
+If you want to handle syntax trees manually, use this.
+For an easier time processing content, use the **[remark][]** ecosystem instead.
+
+You can combine this utility with other utilities to add syntax extensions.
+Notable examples that deeply integrate with it are
+[`mdast-util-gfm`][mdast-util-gfm],
+[`mdast-util-mdx`][mdast-util-mdx],
+[`mdast-util-frontmatter`][mdast-util-frontmatter],
+[`mdast-util-math`][mdast-util-math], and
+[`mdast-util-directive`][mdast-util-directive].
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 14.14+, or 16.0+), install with [npm][]:
+
+```sh
+npm install mdast-util-to-markdown
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {toMarkdown} from 'https://esm.sh/mdast-util-to-markdown@1'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+Say our module `example.js` looks as follows:
+
+```js
+import {toMarkdown} from 'mdast-util-to-markdown'
+
+/** @type {import('mdast').Root} */
+const tree = {
+  type: 'root',
+  children: [
+    {
+      type: 'blockquote',
+      children: [
+        {type: 'thematicBreak'},
+        {
+          type: 'paragraph',
+          children: [
+            {type: 'text', value: '- a\nb !'},
+            {
+              type: 'link',
+              url: 'example.com',
+              children: [{type: 'text', value: 'd'}]
+            }
+          ]
+        }
+      ]
+    }
+  ]
+}
+
+console.log(toMarkdown(tree))
+```
+
+…now running `node example.js` yields:
+
+```markdown
+> ***
+>
+> \- a
+> b \![d](example.com)
+```
+
+> 👉 **Note**: observe the properly escaped characters which would otherwise
+> turn into a list and image respectively.
+
+## API
+
+This package exports the identifiers `toMarkdown` and `defaultHandlers`.
+There is no default export.
+
+### `toMarkdown(tree[, options])`
+
+Turn an **[mdast][]** syntax tree into markdown.
+
+###### Parameters
+
+*   `tree` ([`Node`][node])
+    — tree to serialize
+*   `options` ([`Options`][options], optional)
+    — configuration
+
+###### Returns
+
+Serialized markdown representing `tree` (`string`).
+
+### `defaultHandlers`
+
+Default (CommonMark) handlers ([`Handlers`][handlers]).
+
+### `ConstructName`
+
+Construct names for things generated by `mdast-util-to-markdown` (TypeScript
+type).
+
+This is an enum of strings, each being a semantic label, useful to know when
+serializing whether we’re for example in a double (`"`) or single (`'`) quoted
+title.
+
+###### Type
+
+```ts
+type ConstructName = ConstructNameMap[keyof ConstructNameMap]
+```
+
+### `ConstructNameMap`
+
+Interface of registered constructs (TypeScript type).
+
+###### Type
+
+```ts
+interface ConstructNameMap { /* see code */ }
+```
+
+When working on extensions that use new constructs, extend the corresponding
+interface to register its name:
+
+```ts
+declare module 'mdast-util-to-markdown' {
+  interface ConstructNameMap {
+    // Register a new construct name (value is used, key should match it).
+    gfmStrikethrough: 'gfmStrikethrough'
+  }
+}
+```
+
+### `Handle`
+
+Handle a particular node (TypeScript type).
+
+###### Parameters
+
+*   `node` (`any`)
+    — expected mdast node
+*   `parent` ([`Node`][node], optional)
+    — parent of `node`
+*   `state` ([`State`][state])
+    — info passed around about the current state
+*   `info` ([`Info`][info])
+    — info on the surrounding of the node that is serialized
+
+###### Returns
+
+Serialized markdown representing `node` (`string`).
+
+### `Handlers`
+
+Handle particular nodes (TypeScript type).
+
+Each key is a node type (`Node['type']`), each value its corresponding handler
+([`Handle`][handle]).
+
+###### Type
+
+```ts
+type Handlers = Record
+```
+
+### `Info`
+
+Info on the surrounding of the node that is serialized (TypeScript type).
+
+###### Fields
+
+*   `now` ([`Point`][point])
+    — current point
+*   `lineShift` (`number`)
+    — number of columns each line will be shifted by wrapping nodes
+*   `before` (`string`)
+    — characters before this (guaranteed to be one, can be more)
+*   `after` (`string`)
+    — characters after this (guaranteed to be one, can be more)
+
+### `Join`
+
+How to join two blocks (TypeScript type).
+
+“Blocks” are typically joined by one blank line.
+Sometimes it’s nicer to have them flush next to each other, yet other times
+they cannot occur together at all.
+
+Join functions receive two adjacent siblings and their parent and what they
+return defines how many blank lines to use between them.
+
+###### Parameters
+
+*   `left` ([`Node`][node])
+    — first of two adjacent siblings
+*   `right` ([`Node`][node])
+    — second of two adjacent siblings
+*   `parent` ([`Node`][node])
+    — parent of the two siblings
+*   `state` ([`State`][state])
+    — info passed around about the current state
+
+###### Returns
+
+How many blank lines to use between the siblings (`boolean`, `number`,
+optional).
+
+Where `true` is as passing `1` and `false` means the nodes cannot be
+joined by a blank line, such as two adjacent block quotes or indented code
+after a list, in which case a comment will be injected to break them up:
+
+```markdown
+> Quote 1
+
+
+
+> Quote 2
+```
+
+> 👉 **Note**: abusing this feature will break markdown.
+> One such example is when returning `0` for two paragraphs, which will result
+> in the text running together, and in the future to be seen as one paragraph.
+
+### `Map`
+
+Map function to pad a single line (TypeScript type).
+
+###### Parameters
+
+*   `value` (`string`)
+    — a single line of serialized markdown
+*   `line` (`number`)
+    — line number relative to the fragment
+*   `blank` (`boolean`)
+    — whether the line is considered blank in markdown
+
+###### Returns
+
+Padded line (`string`).
+
+### `Options`
+
+Configuration (TypeScript type).
+
+##### Fields
+
+The following fields influence how markdown is serialized.
+
+###### `options.bullet`
+
+Marker to use for bullets of items in unordered lists (`'*'`, `'+'`, or `'-'`,
+default: `'*'`).
+
+###### `options.bulletOther`
+
+Marker to use in certain cases where the primary bullet doesn’t work (`'*'`,
+`'+'`, or `'-'`, default: depends).
+
+There are three cases where the primary bullet cannot be used:
+
+*   When three list items are on their own, the last one is empty, and `bullet`
+    is also a valid `rule`: `* - +`.
+    This would turn into a thematic break if serialized with three primary
+    bullets.
+    As this is an edge case unlikely to appear in normal markdown, the last list
+    item will be given a different bullet.
+*   When a thematic break is the first child of one of the list items, and
+    `bullet` is the same character as `rule`: `- ***`.
+    This would turn into a single thematic break if serialized with primary
+    bullets.
+    As this is an edge case unlikely to appear in normal markdown this markup is
+    always fixed, even if `bulletOther` is not passed
+*   When two unordered lists appear next to each other: `* a\n- b`.
+    CommonMark sees different bullets as different lists, but several markdown
+    parsers parse it as one list.
+    To solve for both, we instead inject an empty comment between the two lists:
+    `* a\n\n* b`, but if `bulletOther` is given explicitly, it will be
+    used instead
+
+###### `options.bulletOrdered`
+
+Marker to use for bullets of items in ordered lists (`'.'` or `')'`, default:
+`'.'`).
+
+###### `options.bulletOrderedOther`
+
+Marker to use in certain cases where the primary bullet for ordered items
+doesn’t work (`'.'` or `')'`, default: none).
+
+There is one case where the primary bullet for ordered items cannot be used:
+
+*   When two ordered lists appear next to each other: `1. a\n2) b`.
+    CommonMark added support for `)` as a marker, but other markdown parsers
+    do not support it.
+    To solve for both, we instead inject an empty comment between the two lists:
+    `1. a\n\n1. b`, but if `bulletOrderedOther` is given explicitly, it
+    will be used instead
+
+###### `options.closeAtx`
+
+Whether to add the same number of number signs (`#`) at the end of an ATX
+heading as the opening sequence (`boolean`, default: `false`).
+
+###### `options.emphasis`
+
+Marker to use for emphasis (`'*'` or `'_'`, default: `'*'`).
+
+###### `options.fence`
+
+Marker to use for fenced code (``'`'`` or `'~'`, default: ``'`'``).
+
+###### `options.fences`
+
+Whether to use fenced code always (`boolean`, default: `false`).
+The default is to use fenced code if there is a language defined, if the code is
+empty, or if it starts or ends in blank lines.
+
+###### `options.incrementListMarker`
+
+Whether to increment the counter of ordered lists items (`boolean`, default:
+`true`).
+
+###### `options.listItemIndent`
+
+How to indent the content of list items (`'one'`, `'tab'`, or `'mixed'`,
+default: `'tab'`).
+Either with the size of the bullet plus one space (when `'one'`), a tab stop
+(`'tab'`), or depending on the item and its parent list (`'mixed'`, uses `'one'`
+if the item and list are tight and `'tab'` otherwise).
+
+###### `options.quote`
+
+Marker to use for titles (`'"'` or `"'"`, default: `'"'`).
+
+###### `options.resourceLink`
+
+Whether to always use resource links (`boolean`, default: `false`).
+The default is to use autolinks (``) when possible
+and resource links (`[text](url)`) otherwise.
+
+###### `options.rule`
+
+Marker to use for thematic breaks (`'*'`, `'-'`, or `'_'`, default: `'*'`).
+
+###### `options.ruleRepetition`
+
+Number of markers to use for thematic breaks (`number`, default: `3`, min: `3`).
+
+###### `options.ruleSpaces`
+
+Whether to add spaces between markers in thematic breaks (`boolean`, default:
+`false`).
+
+###### `options.setext`
+
+Whether to use setext headings when possible (`boolean`, default: `false`).
+The default is to always use ATX headings (`# heading`) instead of setext
+headings (`heading\n=======`).
+Setext headings cannot be used for empty headings or headings with a rank of
+three or more.
+
+###### `options.strong`
+
+Marker to use for strong (`'*'` or `'_'`, default: `'*'`).
+
+###### `options.tightDefinitions`
+
+Whether to join definitions without a blank line (`boolean`, default: `false`).
+
+The default is to add blank lines between any flow (“block”) construct.
+Turning this option on is a shortcut for a [`Join`][join] function like so:
+
+```js
+function joinTightDefinitions(left, right) {
+  if (left.type === 'definition' && right.type === 'definition') {
+    return 0
+  }
+}
+```
+
+###### `options.handlers`
+
+Handle particular nodes ([`Handlers`][handlers], optional).
+
+###### `options.join`
+
+How to join blocks ([`Array`][join], optional).
+
+###### `options.unsafe`
+
+Schemas that define when characters cannot occur ([`Array`][unsafe],
+optional).
+
+###### `options.extensions`
+
+List of extensions (`Array`, default: `[]`).
+Each extension is an object with the same interface as `Options` itself.
+
+### `SafeConfig`
+
+Configuration passed to `state.safe` (TypeScript type).
+
+###### Fields
+
+*   `before` (`string`)
+    — characters before this (guaranteed to be one, can be more)
+*   `after` (`string`)
+    — characters after this (guaranteed to be one, can be more)
+*   `encode` (`Array`, optional)
+    — extra characters that *must* be encoded (as character references) instead
+    of escaped (character escapes).
+    Only ASCII punctuation will use character escapes, so you never need to
+    pass non-ASCII-punctuation here
+
+### `State`
+
+Info passed around about the current state (TypeScript type).
+
+###### Fields
+
+*   `stack` ([`Array`][constructname])
+    — stack of constructs we’re in
+*   `indexStack` (`Array`)
+    — positions of child nodes in their parents
+*   `associationId` (`(node: Association) => string`)
+    — get an identifier from an association to match it to others (see
+    [`Association`][association])
+*   `enter` (`(construct: ConstructName) => () => void`)
+    — enter a construct (returns a corresponding exit function)
+    (see [`ConstructName`][constructname])
+*   `indentLines` (`(value: string, map: Map) => string`)
+    — pad serialized markdown (see [`Map`][map])
+*   `containerFlow` (`(parent: Node, info: Info) => string`)
+    — serialize flow children (see [`Info`][info])
+*   `containerPhrasing` (`(parent: Node, info: Info) => string`)
+    — serialize phrasing children (see [`Info`][info])
+*   `createTracker` (`(info: Info) => Tracker`)
+    — track positional info in the output (see [`Info`][info],
+    [`Tracker`][tracker])
+*   `safe` (`(value: string, config: SafeConfig) => string`)
+    — make a string safe for embedding (see [`SafeConfig`][safeconfig])
+*   `options` ([`Options`][options])
+    — applied user configuration
+*   `unsafe` ([`Array`][unsafe])
+    — applied unsafe patterns
+*   `join` ([`Array`][join])
+    — applied join handlers
+*   `handle` ([`Handle`][handle])
+    — call the configured handler for the given node
+*   `handlers` ([`Handlers`][handlers])
+    — applied handlers
+*   `bulletCurrent` (`string` or `undefined`)
+    — list marker currently in use
+*   `bulletLastUsed` (`string` or `undefined`)
+    — list marker previously in use
+
+### `Tracker`
+
+Track positional info in the output (TypeScript type).
+
+This info isn’t used yet but such functionality will allow line wrapping,
+source maps, etc.
+
+###### Fields
+
+*   `current` (`() => Info`)
+    — get current tracked info
+*   `shift` (`(value: number) => void`)
+    — define a relative increased line shift (the typical indent for lines)
+*   `move` (`(value: string) => string`)
+    — move past some generated markdown
+
+### `Unsafe`
+
+Schema that defines when a character cannot occur (TypeScript type).
+
+###### Fields
+
+*   `character` (`string`)
+    — single unsafe character
+*   `inConstruct` ([`ConstructName`][constructname], `Array`,
+    optional)
+    — constructs where this is bad
+*   `notInConstruct` ([`ConstructName`][constructname], `Array`,
+    optional)
+    — constructs where this is fine again
+*   `before` (`string`, optional)
+    — `character` is bad when this is before it (cannot be used together with
+    `atBreak`)
+*   `after` (`string`, optional)
+    — `character` is bad when this is after it
+*   `atBreak` (`boolean`, optional)
+    — `character` is bad at a break (cannot be used together with `before`)

+## Syntax
+
+Markdown is serialized according to CommonMark but care is taken to format in
+such a way that the resulting markdown should work with most markdown parsers.
+Extensions can add support for custom syntax.
+
+## Syntax tree
+
+The syntax tree is [mdast][].
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports the additional types `ConstructName`, `ConstructNameMap`, `Handle`,
+`Handlers`, `Info` `Join`, `Map`, `Options`, `SafeConfig`, `State`, and
+`Unsafe`.
+
+## Security
+
+`mdast-util-to-markdown` will do its best to serialize markdown to match the
+syntax tree, but there are several cases where that is impossible.
+It’ll do its best, but complete roundtripping is impossible given that any value
+could be injected into the tree.
+
+As markdown is sometimes used for HTML, and improper use of HTML can open you up
+to a [cross-site scripting (XSS)][xss] attack, use of `mdast-util-to-markdown`
+and parsing it again later could potentially be unsafe.
+When parsing markdown afterwards and then going to HTML, use something like
+[`hast-util-sanitize`][hast-util-sanitize] to make the tree safe.

+
+## What is this?
+
+This package is a tiny utility that gets the textual content of a node.
+
+## When should I use this?
+
+This utility is useful when you have a node, say a heading, and want to get the
+text inside it.
+
+This package does not serialize markdown, that’s what
+[`mdast-util-to-markdown`][mdast-util-to-markdown] does.
+
+Similar packages, [`hast-util-to-string`][hast-util-to-string] and
+[`hast-util-to-text`][hast-util-to-text], do the same but on [hast][].
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 14.14+ and 16.0+), install with [npm][]:
+
+```sh
+npm install mdast-util-to-string
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {toString} from 'https://esm.sh/mdast-util-to-string@3'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import {unified} from 'unified'
+import {fromMarkdown} from 'mdast-util-from-markdown'
+import {toString} from 'mdast-util-to-string'
+
+const tree = fromMarkdown('Some _emphasis_, **importance**, and `code`.')
+
+console.log(toString(tree)) // => 'Some emphasis, importance, and code.'
+```
+
+## API
+
+This package exports the identifier [`toString`][api-tostring].
+There is no default export.
+
+### `toString(value[, options])`
+
+Get the text content of a node or list of nodes.
+
+Prefers the node’s plain-text fields, otherwise serializes its children,
+and if the given value is an array, serialize the nodes in it.
+
+###### Parameters
+
+*   `value` (`unknown`)
+    — thing to serialize, typically [`Node`][node]
+*   `options` ([`Options`][api-options], optional)
+    — configuration
+
+###### Returns
+
+Serialized `value` (`string`).
+
+### `Options`
+
+Configuration (TypeScript type).
+
+###### Fields
+
+*   `includeImageAlt` (`boolean`, default: `true`)
+    — whether to use `alt` for `image`s
+*   `includeHtml` (`boolean`, default: `true`)
+    — whether to use `value` of HTML
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports the additional type [`Options`][api-options].
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with all maintained
+versions of Node.js.
+As of now, that is Node.js 14.14+ and 16.0+.
+Our projects sometimes work with older versions, but this is not guaranteed.
+
+## Security
+
+Use of `mdast-util-to-string` does not involve **[hast][]**, user content, or
+change the tree, so there are no openings for [cross-site scripting (XSS)][xss]
+attacks.

+## Install
+
+[npm][]:
+
+```sh
+npm install micromark-core-commonmark
+```
+
+## Use
+
+```js
+import {autolink} from 'micromark-core-commonmark'
+
+console.log(autolink) // Do things with `autolink`.
+```
+
+## API
+
+This module exports the following identifiers: `attention`, `autolink`,
+`blankLine`, `blockQuote`, `characterEscape`, `characterReference`,
+`codeFenced`, `codeIndented`, `codeText`, `content`, `definition`,
+`hardBreakEscape`, `headingAtx`, `htmlFlow`, `htmlText`, `labelEnd`,
+`labelStartImage`, `labelStartLink`, `lineEnding`, `list`, `setextUnderline`,
+`thematicBreak`.
+There is no default export.
+
+Each identifier refers to a [construct](https://github.com/micromark/micromark#constructs).
+
+See the code for more on the exported constructs.

+## API
+
+This module exports the following identifiers: `factoryDestination`.
+There is no default export.
+
+### `factoryDestination(…)`
+
+###### Parameters
+
+*   `effects` (`Effects`) — Context
+*   `ok` (`State`) — State switched to when successful
+*   `nok` (`State`) — State switched to when not successful
+*   `type` (`string`) — Token type for whole (`` or `b`)
+*   `literalType` (`string`) — Token type when enclosed (``)
+*   `literalMarkerType` (`string`) — Token type for enclosing (`<` and `>`)
+*   `rawType` (`string`) — Token type when not enclosed (`b`)
+*   `stringType` (`string`) — Token type for the URI (`a` or `b`)
+*   `max` (`number`, default: `Infinity`) — Max depth of nested parens
+
+###### Returns
+
+`State`.
+
+###### Examples
+
+```markdown
+
+b>
+
+
+a
+a\)b
+a(b)c
+a(b)
+```

+
+## API
+
+This module exports the following identifiers: `factoryLabel`.
+There is no default export.
+
+### `factoryLabel(…)`
+
+Note that labels in markdown are capped at 999 characters in the string.
+
+###### Parameters
+
+*   `this` (`TokenizeContext`) — Tokenize context
+*   `effects` (`Effects`) — Context
+*   `ok` (`State`) — State switched to when successful
+*   `nok` (`State`) — State switched to when not successful
+*   `type` (`string`) — Token type for whole (`[a]`)
+*   `markerType` (`string`) — Token type for the markers (`[` and `]`)
+*   `stringType` (`string`) — Token type for the identifier (`a`)
+
+###### Returns
+
+`State`.
+
+###### Examples
+
+```markdown
+[a]
+[a
+b]
+[a\]b]

+
+## Use
+
+```js
+import {factorySpace} from 'micromark-factory-space'
+import {codes} from 'micromark-util-symbol/codes'
+import {types} from 'micromark-util-symbol/types'
+
+// A micromark tokenizer that uses the factory:

+    effects.consume(code)
+    return info
+  }
+
+  // …
+}
+```
+
+## API
+
+This module exports the following identifiers: `factorySpace`.
+There is no default export.
+
+### `factorySpace(…)`
+
+Note that there is no `nok` parameter:
+
+*   spaces in markdown are often optional, in which case this factory can be
+    used and `ok` will be switched to whether spaces were found or not,
+*   One space character can be detected with
+    [markdownSpace(code)][markdown-space] right before using `factorySpace`
+
+###### Parameters
+
+*   `effects` (`Effects`) — Context
+*   `ok` (`State`) — State switched to when successful
+*   `type` (`string`) — Token type for whole (`' \t'`)
+*   `max` (`number`, default: `Infinity`) — Max size of whitespace
+
+###### Returns
+
+`State`.
+
+###### Examples
+
+Where `␉` represents a tab (plus how much it expands) and `␠` represents a
+single space.
+
+```markdown
+␉
+␠␠␠␠
+␉␠
+```

+```
+
+## API
+
+This module exports the following identifiers: `factoryWhitespace`.
+There is no default export.
+
+### `factoryWhitespace(…)`
+
+Note that there is no `nok` parameter:
+
+*   line endings or spaces in markdown are often optional, in which case this
+    factory can be used and `ok` will be switched to whether spaces were found
+    or not,
+*   One line ending or space can be detected with
+    [markdownLineEndingOrSpace(code)][ws] right before using `factoryWhitespace`
+
+###### Parameters
+
+*   `effects` (`Effects`) — Context
+*   `ok` (`State`) — State switched to when successful
+
+###### Returns
+
+`State`.

+## Install
+
+[npm][]:
+
+```sh
+npm install micromark-util-character
+```
+
+## Use
+
+```js
+import {asciiAlpha} from 'micromark-util-character'
+
+console.log(asciiAlpha(64)) // false
+console.log(asciiAlpha(65)) // true
+```
+
+## API
+
+This module exports the following identifiers: `asciiAlpha`,
+`asciiAlphanumeric`, `asciiAtext`, `asciiControl`, `asciiDigit`,
+`asciiHexDigit`, `asciiPunctuation`, `markdownLineEnding`,
+`markdownLineEndingOrSpace`, `markdownSpace`, `unicodePunctuation`,
+`unicodeWhitespace`.
+There is no default export.
+
+### `asciiAlpha(code)`
+
+Check whether the
+[character code](https://github.com/micromark/micromark#preprocess)
+represents an ASCII alpha (`a` through `z`,
+case insensitive).
+
+An **ASCII alpha** is an ASCII upper alpha or ASCII lower alpha.
+
+An **ASCII upper alpha** is a character in the inclusive range U+0041 (`A`)
+to U+005A (`Z`).
+
+An **ASCII lower alpha** is a character in the inclusive range U+0061 (`a`)
+to U+007A (`z`).
+
+### `asciiDigit(code)`
+
+Check whether the
+[character code](https://github.com/micromark/micromark#preprocess)
+represents an ASCII digit (`0` through `9`).
+
+An **ASCII digit** is a character in the inclusive range U+0030 (`0`) to
+U+0039 (`9`).
+
+### `asciiHexDigit(code)`
+
+Check whether the
+[character code](https://github.com/micromark/micromark#preprocess)
+represents an ASCII hex digit (`a` through `f`, case insensitive, or `0` through
+`9`).
+
+An **ASCII hex digit** is an ASCII digit (see `asciiDigit`), ASCII upper hex
+digit, or an ASCII lower hex digit.
+
+An **ASCII upper hex digit** is a character in the inclusive range U+0041
+(`A`) to U+0046 (`F`).
+
+An **ASCII lower hex digit** is a character in the inclusive range U+0061
+(`a`) to U+0066 (`f`).
+
+### `asciiAlphanumeric(code)`
+
+Check whether the
+[character code](https://github.com/micromark/micromark#preprocess)
+represents an ASCII alphanumeric (`a` through `z`, case insensitive, or `0`
+through `9`).
+
+An **ASCII alphanumeric** is an ASCII digit (see `asciiDigit`) or ASCII alpha
+(see `asciiAlpha`).
+
+### `asciiPunctuation(code)`
+
+Check whether the
+[character code](https://github.com/micromark/micromark#preprocess)
+represents ASCII punctuation.
+
+An **ASCII punctuation** is a character in the inclusive ranges U+0021
+EXCLAMATION MARK (`!`) to U+002F SLASH (`/`), U+003A COLON (`:`) to U+0040 AT
+SIGN (`@`), U+005B LEFT SQUARE BRACKET (`[`) to U+0060 GRAVE ACCENT
+(`` ` ``), or U+007B LEFT CURLY BRACE (`{`) to U+007E TILDE (`~`).
+
+### `asciiAtext(code)`
+
+Check whether the
+[character code](https://github.com/micromark/micromark#preprocess)
+represents an ASCII atext.
+
+atext is an ASCII alphanumeric (see `asciiAlphanumeric`), or a character in
+the inclusive ranges U+0023 NUMBER SIGN (`#`) to U+0027 APOSTROPHE (`'`),
+U+002A ASTERISK (`*`), U+002B PLUS SIGN (`+`), U+002D DASH (`-`), U+002F
+SLASH (`/`), U+003D EQUALS TO (`=`), U+003F QUESTION MARK (`?`), U+005E
+CARET (`^`) to U+0060 GRAVE ACCENT (`` ` ``), or U+007B LEFT CURLY BRACE
+(`{`) to U+007E TILDE (`~`) (**\[RFC5322]**).
+
+See **\[RFC5322]**:\
+[Internet Message Format](https://tools.ietf.org/html/rfc5322).\
+P. Resnick.\
+IETF.
+
+### `asciiControl(code)`
+
+Check whether a
+[character code](https://github.com/micromark/micromark#preprocess)
+is an ASCII control character.
+
+An **ASCII control** is a character in the inclusive range U+0000 NULL (NUL)
+to U+001F (US), or U+007F (DEL).
+
+### `markdownLineEndingOrSpace(code)`
+
+Check whether a
+[character code](https://github.com/micromark/micromark#preprocess)
+is a markdown line ending (see `markdownLineEnding`) or markdown space (see
+`markdownSpace`).
+
+### `markdownLineEnding(code)`
+
+Check whether a
+[character code](https://github.com/micromark/micromark#preprocess)
+is a markdown line ending.
+
+A **markdown line ending** is the virtual characters M-0003 CARRIAGE RETURN
+LINE FEED (CRLF), M-0004 LINE FEED (LF) and M-0005 CARRIAGE RETURN (CR).
+
+In micromark, the actual character U+000A LINE FEED (LF) and U+000D CARRIAGE
+RETURN (CR) are replaced by these virtual characters depending on whether
+they occurred together.
+
+### `markdownSpace(code)`
+
+Check whether a
+[character code](https://github.com/micromark/micromark#preprocess)
+is a markdown space.
+
+A **markdown space** is the concrete character U+0020 SPACE (SP) and the
+virtual characters M-0001 VIRTUAL SPACE (VS) and M-0002 HORIZONTAL TAB (HT).
+
+In micromark, the actual character U+0009 CHARACTER TABULATION (HT) is
+replaced by one M-0002 HORIZONTAL TAB (HT) and between 0 and 3 M-0001 VIRTUAL
+SPACE (VS) characters, depending on the column at which the tab occurred.
+
+### `unicodeWhitespace(code)`
+
+Check whether the
+[character code](https://github.com/micromark/micromark#preprocess)
+represents Unicode whitespace.
+
+Note that this does handle micromark specific markdown whitespace characters.
+See `markdownLineEndingOrSpace` to check that.
+
+A **Unicode whitespace** is a character in the Unicode `Zs` (Separator,
+Space) category, or U+0009 CHARACTER TABULATION (HT), U+000A LINE FEED (LF),
+U+000C (FF), or U+000D CARRIAGE RETURN (CR) (**\[UNICODE]**).
+
+See **\[UNICODE]**:\
+[The Unicode Standard](https://www.unicode.org/versions/).\
+Unicode Consortium.
+
+### `unicodePunctuation(code)`
+
+Check whether the
+[character code](https://github.com/micromark/micromark#preprocess)
+represents Unicode punctuation.
+
+A **Unicode punctuation** is a character in the Unicode `Pc` (Punctuation,
+Connector), `Pd` (Punctuation, Dash), `Pe` (Punctuation, Close), `Pf`
+(Punctuation, Final quote), `Pi` (Punctuation, Initial quote), `Po`
+(Punctuation, Other), or `Ps` (Punctuation, Open) categories, or an ASCII
+punctuation (see `asciiPunctuation`) (**\[UNICODE]**).

+
+## Install
+
+[npm][]:
+
+```sh
+npm install micromark-util-chunked
+```
+
+## Use
+
+```js
+import {push, splice} from 'micromark-util-chunked'
+
+// …
+
+nextEvents = push(nextEvents, [
+  ['enter', events[open][1], context],
+  ['exit', events[open][1], context]
+])
+
+// …
+
+splice(events, open - 1, index - open + 3, nextEvents)
+
+// …
+```
+
+## API
+
+This module exports the following identifiers: `push`, `splice`.
+There is no default export.
+
+### `push(list, items)`
+
+Append `items` (an array) at the end of `list` (another array).
+When `list` was empty, returns `items` instead.
+
+This prevents a potentially expensive operation when `list` is empty,
+and adds items in batches to prevent V8 from hanging.
+
+###### Parameters
+
+*   `list` (`unknown[]`) — List to operate on
+*   `items` (`unknown[]`) — Items to add to `list`
+
+###### Returns
+
+`list` or `items`
+
+### `splice(list, start, remove, items)`
+
+Like `Array#splice`, but smarter for giant arrays.
+
+`Array#splice` takes all items to be inserted as individual argument which
+causes a stack overflow in V8 when trying to insert 100k items for instance.
+
+Otherwise, this does not return the removed items, and takes `items` as an
+array instead of rest parameters.
+
+###### Parameters
+
+*   `list` (`unknown[]`) — List to operate on
+*   `start` (`number`) — Index to remove/insert at (can be negative)
+*   `remove` (`number`) — Number of items to remove
+*   `items` (`unknown[]`) — Items to inject into `list`
+
+###### Returns
+
+`void`

+```js
+import {decodeNumericCharacterReference} from 'micromark-util-decode-numeric-character-reference'
+
+decodeNumericCharacterReference('41', 16) // 'A'
+decodeNumericCharacterReference('65', 10) // 'A'
+decodeNumericCharacterReference('A', 16) // '\n'
+decodeNumericCharacterReference('7F', 16) // '�' - Control
+decodeNumericCharacterReference('110000', 16) // '�' - Out of range
+```
+
+## API
+
+This module exports the following identifiers:
+`decodeNumericCharacterReference`.
+There is no default export.
+
+### `decodeNumericCharacterReference(value)`
+
+Sort of like `String.fromCharCode(Number.parseInt(value, base))`,
+but makes non-characters and control characters safe.
+
+###### Parameters
+
+*   `value` (`string`) — Value to decode.
+*   `base` (`number`, probably `10` or `16`) — Numeric base.
+
+###### Returns
+
+`string` — Character code.

+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 12.20+, 14.14+, 16.0+, 18.0+), install with [npm][]:
+
+```sh
+npm install micromark-util-html-tag-name
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {htmlBlockNames, htmlRawNames} from 'https://esm.sh/micromark-util-html-tag-name@1'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import {htmlBlockNames, htmlRawNames} from 'micromark-util-html-tag-name'
+
+console.log(htmlBlockNames) // ['address', 'article', …]
+console.log(htmlRawNames) // ['pre', 'script', …]
+```
+
+## API
+
+This module exports the following identifiers: `htmlBlockNames`,
+`htmlRawNames`.
+There is no default export.
+
+### `htmlBlockNames`
+
+List of lowercase HTML tag names (`Array`) which when parsing HTML
+(flow), result in more relaxed rules (condition 6): because they are known
+blocks, the HTML-like syntax doesn’t have to be strictly parsed.
+For tag names not in this list, a more strict algorithm (condition 7) is used
+to detect whether the HTML-like syntax is seen as HTML (flow) or not.
+
+This is copied from: .
+
+### `htmlRawNames`
+
+List of lowercase HTML tag names (`Array`) which when parsing HTML
+(flow), result in HTML that can include lines w/o exiting, until a closing tag
+also in this list is found (condition 1).
+
+This is copied from:
+.
+
+Note that `textarea` was added in `CommonMark@0.30`.

+normalizeIdentifier('ТОЛПОЙ') // 'ТОЛПОЙ'
+normalizeIdentifier('Толпой') // 'ТОЛПОЙ'
+```
+
+## API
+
+This module exports the following identifiers: `normalizeIdentifier`.
+There is no default export.
+
+### `normalizeIdentifier(value)`
+
+Normalize an identifier (such as used in definitions).
+Collapse Markdown whitespace, trim, and then lower- and uppercase.
+
+Some characters are considered “uppercase”, such as U+03F4 (`ϴ`), but if their
+lowercase counterpart (U+03B8 (`θ`)) is uppercased will result in a different
+uppercase character (U+0398 (`Θ`)).
+Hence, to get that form, we perform both lower- and uppercase.
+
+Using uppercase last makes sure keys will not interact with default prototypal
+methods: no method is uppercase.
+
+###### Parameters
+
+*   `value` (`string`) — Identifier to normalize.
+
+###### Returns
+
+`string` — Normalized value.

+
+micromark utility to resolve subtokens.
+
+[Resolvers][resolver] are functions that take events and manipulate them.
+This is needed for example because media (links, images) and attention (strong,
+italic) aren’t parsed left-to-right.
+Instead, their openings and closings are parsed, and when done, their openings
+and closings are matched, and left overs are turned into plain text.
+Because media and attention can’t overlap, we need to perform that operation
+when one closing matches an opening, too.

+
+```sh
+npm install micromark-util-resolve-all
+```
+
+## Use
+
+```js
+import {push} from 'micromark-util-chunked'
+import {resolveAll} from 'micromark-util-resolve-all'
+
+/**
+ * @type {Resolver}
+ */
+function resolveAllAttention(events, context) {
+  // …
+
+  // Walk through all events.
+  while (++index < events.length) {

+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 12.20+, 14.14+, 16.0+, 18.0+), install with [npm][]:
+
+```sh
+npm install micromark-util-sanitize-uri
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {sanitizeUri} from 'https://esm.sh/micromark-util-sanitize-uri@1'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import {sanitizeUri} from 'micromark-util-sanitize-uri'
+
+sanitizeUri('https://example.com/a&b') // 'https://example.com/a&amp;b'
+sanitizeUri('https://example.com/a%b') // 'https://example.com/a%25b'
+sanitizeUri('https://example.com/a%20b') // 'https://example.com/a%20b'
+sanitizeUri('https://example.com/👍') // 'https://example.com/%F0%9F%91%8D'
+sanitizeUri('https://example.com/', /^https?$/i) // 'https://example.com/'
+sanitizeUri('javascript:alert(1)', /^https?$/i) // ''
+sanitizeUri('./example.jpg', /^https?$/i) // './example.jpg'
+sanitizeUri('#a', /^https?$/i) // '#a'
+```
+
+## API
+
+This module exports the following identifiers: `sanitizeUri`.
+There is no default export.
+
+### `sanitizeUri(url[, pattern])`
+
+Make a value safe for injection as a URL.
+
+This encodes unsafe characters with percent-encoding and skips already
+encoded sequences (see `normalizeUri` internally).
+Further unsafe characters are encoded as character references (see
+`micromark-util-encode`).
+
+A regex of allowed protocols can be given, in which case the URL is sanitized.
+For example, `/^(https?|ircs?|mailto|xmpp)$/i` can be used for `a[href]`, or
+`/^https?$/i` for `img[src]` (this is what `github.com` allows).
+If the URL includes an unknown protocol (one not matched by `protocol`, such
+as a dangerous example, `javascript:`), the value is ignored.
+
+###### Parameters
+
+*   `url` (`string`) — URI to sanitize.
+*   `pattern` (`RegExp`, optional) — Allowed protocols.
+
+###### Returns
+
+`string` — Sanitized URI.
+
+### `normalizeUri(url[, pattern])`
+
+Normalize a URL (such as used in definitions).
+
+Encode unsafe characters with percent-encoding, skipping already encoded
+sequences.
+
+###### Parameters
+
+*   `url` (`string`) — URI to normalize.
+
+###### Returns
+
+`string` — Normalized URI.

+npm install micromark-util-subtokenize
+```
+
+## Use
+
+```js
+import {subtokenize} from 'micromark-util-subtokenize'
+
+/**
+ * Content is transparent: it’s parsed right now. That way, definitions are also
+ * parsed right now: before text in paragraphs (specifically, media) are parsed.
+ *
+ * @type {Resolver}
+ */
+function resolveContent(events) {
+  subtokenize(events)
+  return events
+}
+```
+
+## API
+
+This module exports the following identifiers: `subtokenize`.
+There is no default export.
+
+### `subtokenize(events)`
+
+Tokenize subcontent.
+
+###### Parameters
+
+*   `events` (`Event[]`) — List of events
+
+###### Returns
+
+`boolean` — Whether subtokens were found.

+ * and the end-of-file (eof) character.
+ * As values are preprocessed before handling them, the actual characters LF,
+ * CR, HT, and NUL (which is present as the replacement character), are
+ * guaranteed to not exist.

+
+## Use
+
+```js
+import {codes} from 'micromark-util-symbol/codes'

+```
+
+## API
+
+This package has four entries in its export map: `micromark-util-symbol/codes`,
+`micromark-util-symbol/constants`, `micromark-util-symbol/types`,
+`micromark-util-symbol/values`.
+
+Each module exports an identifier with the same name (for example,
+`micromark-util-symbol/codes` has `codes`), which is an object mapping strings
+to other values.
+
+Take a peek at the code to learn more!

+import {micromark} from 'micromark'
+
+console.log(micromark('## Hello, *world*!'))
+```
+
+Yields:
+
+```html
+
Hello, world!

+```
+
+You can pass extensions (in this case [`micromark-extension-gfm`][gfm]):
+
+```js
+import {micromark} from 'micromark'
+import {gfm, gfmHtml} from 'micromark-extension-gfm'
+
+const value = '* [x] contact@example.com ~~strikethrough~~'
+
+const result = micromark(value, {
+  extensions: [gfm()],
+  htmlExtensions: [gfmHtml()]
+})
+
+console.log(result)
+```
+
+Yields:
+
+```html
+
+```
+
+Streaming interface:
+
+```js
+import fs from 'fs'
+import {stream} from 'micromark/stream'
+
+fs.createReadStream('example.md')
+  .on('error', handleError)
+  .pipe(stream())
+  .pipe(process.stdout)
+
+function handleError(error) {
+  // Handle your error here!
+  throw error
+}
+```
+
+## API
+
+`micromark` core has two entries in its export map: `micromark` and
+`micromark/stream`.
+
+`micromark` exports the following identifier: `micromark`.
+`micromark/stream` exports the following identifier: `stream`.
+There are no default exports.
+
+The export map supports the endorsed
+[`development` condition](https://nodejs.org/api/packages.html#packages_resolving_user_conditions).
+Run `node --conditions development module.js` to get instrumented dev code.
+Without this condition, production code is loaded.
+See [§ Size & debug][size-debug] for more info.
+
+### `micromark(value[, encoding][, options])`
+
+Compile markdown to HTML.
+
+##### Parameters
+
+###### `value`
+
+Markdown to parse (`string` or `Buffer`).
+
+###### `encoding`
+
+[Character encoding][encoding] to understand `value` as when it’s a
+[`Buffer`][buffer] (`string`, default: `'utf8'`).
+
+###### `options.defaultLineEnding`
+
+Value to use for line endings not in `value` (`string`, default: first line
+ending or `'\n'`).
+
+Generally, micromark copies line endings (`'\r'`, `'\n'`, `'\r\n'`) in the
+markdown document over to the compiled HTML.
+In some cases, such as `> a`, CommonMark requires that extra line endings are
+added: `
\n
a
\n
`.
+
+###### `options.allowDangerousHtml`
+
+Whether to allow embedded HTML (`boolean`, default: `false`).
+See [§ Security][security].
+
+###### `options.allowDangerousProtocol`
+
+Whether to allow potentially dangerous protocols in links and images (`boolean`,
+default: `false`).
+URLs relative to the current protocol are always allowed (such as, `image.jpg`).
+For links, the allowed protocols are `http`, `https`, `irc`, `ircs`, `mailto`,
+and `xmpp`.
+For images, the allowed protocols are `http` and `https`.
+See [§ Security][security].
+
+###### `options.extensions`
+
+Array of syntax extensions ([`Array`][syntax-extension],
+default: `[]`).
+See [§ Extensions][extensions].
+
+###### `options.htmlExtensions`
+
+Array of HTML extensions ([`Array`][html-extension], default:
+`[]`).
+See [§ Extensions][extensions].
+
+##### Returns
+
+`string` — Compiled HTML.
+
+### `stream(options?)`
+
+Streaming interface of micromark.
+Compiles markdown to HTML.
+`options` are the same as the buffering API above.
+Note that some of the work to parse markdown can be done streaming, but in the
+end buffering is required.
+
+micromark does not handle errors for you, so you must handle errors on whatever
+streams you pipe into it.
+As markdown does not know errors, `micromark` itself does not emit errors.
+
+## Extensions
+
+micromark supports extensions.
+There are two types of extensions for micromark:
+[`SyntaxExtension`][syntax-extension],
+which change how markdown is parsed, and [`HtmlExtension`][html-extension],
+which change how it compiles.
+They can be passed in [`options.extensions`][option-extensions] or
+[`options.htmlExtensions`][option-htmlextensions], respectively.
+
+As a user of extensions, refer to each extension’s readme for more on how to use
+them.
+As a (potential) author of extensions, refer to
+[§ Extending markdown][extending-markdown] and
+[§ Creating a micromark extension][create-extension].

+
+### `SyntaxExtension`
+
+A syntax extension is an object whose fields are typically the names of hooks,
+referring to where constructs “hook” into.
+The fields at such objects are character codes, mapping to constructs as values.
+
+The built in [constructs][] are an example.
+See it and [existing extensions][extensions] for inspiration.
+
+### `HtmlExtension`
+
+An HTML extension is an object whose fields are typically `enter` or `exit`
+(reflecting whether a token is entered or exited).
+The values at such objects are names of tokens mapping to handlers.
+
+See [existing extensions][extensions] for inspiration.
+
+### Extending markdown
+
+micromark lets you change markdown syntax, yes, but there are alternatives.
+The alternatives are often better.
+
+Over the years, many micromark and remark users have asked about their unique
+goals for markdown.
+Some exemplary goals are:
+
+1.  I want to add `rel="nofollow"` to external links
+2.  I want to add links from headings to themselves
+3.  I want line breaks in paragraphs to become hard breaks
+4.  I want to support embedded music sheets
+5.  I want authors to add arbitrary attributes
+6.  I want authors to mark certain blocks with meaning, such as tip, warning,
+    etc
+7.  I want to combine markdown with JS(X)
+8.  I want to support our legacy flavor of markdown-like syntax
+
+These can be solved in different ways and which solution is best is both
+subjective and dependant on unique needs.
+Often, there is already a solution in the form of an existing remark or rehype
+plugin.
+Respectively, their solutions are:
+
+1.  [`remark-external-links`](https://github.com/remarkjs/remark-external-links)
+2.  [`rehype-autolink-headings`](https://github.com/rehypejs/rehype-autolink-headings)
+3.  [`remark-breaks`](https://github.com/remarkjs/remark-breaks)
+4.  custom plugin similar to
+    [`rehype-katex`](https://github.com/remarkjs/remark-math/tree/main/packages/rehype-katex)
+    but integrating [`abcjs`](https://www.abcjs.net)
+5.  either [`remark-directive`](https://github.com/remarkjs/remark-directive)
+    and a custom plugin or with
+    [`rehype-attr`](https://github.com/jaywcjlove/rehype-attr)
+6.  [`remark-directive`](https://github.com/remarkjs/remark-directive)
+    combined with a custom plugin
+7.  combining the existing micromark MDX extensions however you please, such as
+    done by [`mdx-js/mdx`](https://github.com/mdx-js/mdx) or
+    [`xdm`](https://github.com/wooorm/xdm)
+8.  Writing a micromark extension
+
+Looking at these from a higher level, they can be categorized:
+
+*   **Changing the output by transforming syntax trees**
+    (1 and 2)
+
+    This category is nice as the format remains plain markdown that authors are
+    already familiar with and which will work with existing tools and platforms.
+
+    Implementations will deal with the syntax tree
+    ([`mdast`][mdast]) and the ecosystems
+    **[remark][]** and **[rehype][]**.
+    There are many existing
+    [utilities for working with that tree][utilities].
+    Many [remark plugins][] and [rehype plugins][] also exist.
+*   **Using and abusing markdown to add new meaning**
+    (3, 4, potentially 5)
+
+    This category is similar to *Changing the output by transforming syntax
+    trees*, but adds a new meaning to certain things which already have
+    semantics in markdown.
+
+    Some examples in pseudo code:
+
+    ````markdown
+    *   **A list item with the first paragraph bold**
+
+        And then more content, is turned into `
` / `
` / `
` elements
+
+    Or, the title attributes on links or images is [overloaded](/url 'rel:nofollow')
+    with a new meaning.
+
+    ```csv
+    fenced,code,can,include,data
+    which,is,turned,into,a,graph
+    ```
+
+    ```js data can="be" passed=true
+    // after the code language name
+    ```
+
+    HTML, especially comments, could be used as **markers**
+    ````
+*   **Arbitrary extension mechanism**
+    (potentially 5; 6)
+
+    This category is nice when content should contain embedded “components”.
+    Often this means it’s required for authors to have some programming
+    experience.
+    There are three good ways to solve arbitrary extensions.
+
+    **HTML**: Markdown already has an arbitrary extension syntax.
+    It works in most places and authors are already familiar with the syntax,
+    but it’s reasonably hard to implement securely.
+    Certain platforms will remove HTML completely, others sanitize it to varying
+    degrees.
+    HTML also supports custom elements.
+    These could be used and enhanced by client side JavaScript or enhanced when
+    transforming the syntax tree.
+
+    **Generic directives**: although
+    [a proposal][directive-proposal]
+    and not supported on most platforms, directives do work with many tools
+    already.
+    They’re not the easiest to author compared to, say, a heading, but sometimes
+    that’s okay.
+    They do have potential: they nicely solve the need for an infinite number of
+    potential extensions to markdown in a single markdown-esque way.
+
+    **MDX** also adds support for components by swapping HTML out for JS(X).
+    JSX is an extension to JavaScript, so MDX is something along the lines of
+    literate programming.
+    This does require knowledge of React (or Vue) and JavaScript, excluding some
+    authors.
+*   **Extending markdown syntax**
+    (7 and 8)
+
+    Extend the syntax of markdown means:
+
+    *   Authors won’t be familiar with the syntax
+    *   Content won’t work in other places (such as on GitHub)
+    *   Defeating the purpose of markdown: being simple to author and looking
+        like what it means
+
+    …and it’s hard to do as it requires some in-depth knowledge of JavaScript
+    and parsing.
+    But it’s possible and in certain cases very powerful.
+
+### Creating a micromark extension
+
+This section shows how to create an extension for micromark that parses
+“variables” (a way to render some data) and one to turn a default construct off.
+
+> Stuck?
+> See [`support.md`][support].
+
+#### Prerequisites
+
+*   You should possess an intermediate to high understanding of JavaScript:
+    it’s going to get a bit complex
+*   Read the readme of [unified][] (until you hit the API section) to better
+    understand where micromark fits
+*   Read the [§ Architecture][architecture] section to understand how micromark
+    works
+*   Read the [§ Extending markdown][extending-markdown] section to understand
+    whether it’s a good idea to extend the syntax of markdown
+
+#### Extension basics
+
+micromark supports two types of extensions.
+Syntax extensions change how markdown is parsed.
+HTML extensions change how it compiles.
+
+HTML extensions are not always needed, as micromark is often used through
+[`mdast-util-from-markdown`][from-markdown] to parse to a markdown syntax tree
+So instead of an HTML extension a `from-markdown` utility is needed.
+Then, a [`mdast-util-to-markdown`][to-markdown] utility, which is responsible
+for serializing syntax trees to markdown, is also needed.
+
+When developing something for internal use only, you can pick and choose which
+parts you need.
+When open sourcing your extensions, it should probably contain four parts:
+syntax extension, HTML extension, `from-markdown` utility, and a `to-markdown`
+utility.
+
+On to our first case!
+
+#### Case: variables
+
+Let’s first outline what we want to make: render some data, similar to how
+[Liquid](https://github.com/Shopify/liquid/wiki/Liquid-for-Designers) and the
+like work, in our markdown.
+It could look like this:
+
+```markdown
+Hello, {planet}!
+```
+
+Turned into:
+
+```html
+
Hello, Venus!

+```
+
+An opening curly brace, followed by one or more characters, and then a closing
+brace.
+We’ll then look up `planet` in some object and replace the variable with its
+corresponding value, to get something like `Venus` out.
+
+It looks simple enough, but with markdown there are often a couple more things
+to think about.
+For this case, I can see the following:
+
+*   Is there a “block” version too?
+*   Are spaces allowed?
+    Line endings?
+    Should initial and final white space be ignored?
+*   Balanced nested braces?
+    Superfluous ones such as `{{planet}}` or meaningful ones such as
+    `{a {pla} net}`?
+*   Character escapes (`{pla\}net}`) and character references
+    (`{pla}net}`)?
+
+To keep things as simple as possible, let’s not support a block syntax, see
+spaces as special, support line endings, or support nested braces.
+But to learn interesting things, we *will* support character escapes and
+\-references.
+
+Note that this particular case is already solved quite nicely by
+[`micromark-extension-mdx-expression`][mdx-expression].
+It’s a bit more powerful and does more things, but it can be used to solve this
+case and otherwise serve as inspiration.
+
+##### Setup
+
+Create a new folder, enter it, and set up a new package:
+
+```sh
+mkdir example
+cd example
+npm init -y
+```
+
+In this example we’ll use ESM, so add `type: 'module'` to `package.json`:
+
+```diff
+@@ -2,6 +2,7 @@
+   "name": "example",
+   "version": "1.0.0",
+   "description": "",
++  "type": "module",
+   "main": "index.js",
+   "scripts": {
+     "test": "echo \"Error: no test specified\" && exit 1"
+```
+
+Add a markdown file, `example.md`, with the following text:
+
+```markdown
+Hello, {planet}!
+
+{pla\}net} and {pla}net}.
+```
+
+To check if our extension works, add an `example.js` module, with the following
+code:
+
+```js
+import {promises as fs} from 'node:fs'
+import {micromark} from 'micromark'
+import {variables} from './index.js'
+
+main()
+
+async function main() {
+  const buf = await fs.readFile('example.md')
+  const out = micromark(buf, {extensions: [variables]})
+  console.log(out)
+}
+```
+
+While working on the extension, run `node example` to see whether things work.
+Feel free to add more examples of the variables syntax in `example.md` if
+needed.
+
+Our extension doesn’t work yet, for one because `micromark` is not installed:
+
+```sh
+npm install micromark --save-dev
+```
+
+…and we need to write our extension.
+Let’s do that in `index.js`:
+
+```js
+export const variables = {}
+```
+
+Although our extension doesn’t do anything, running `node example` now somewhat
+works!
+
+##### Syntax extension
+
+Much in micromark is based on character codes (see [§ Preprocess][preprocess]).
+For this extension, the relevant codes are:
+
+*   `-5`
+    — M-0005 CARRIAGE RETURN (CR)
+*   `-4`
+    — M-0004 LINE FEED (LF)
+*   `-3`
+    — M-0003 CARRIAGE RETURN LINE FEED (CRLF)
+*   `null`
+    — EOF (end of the stream)
+*   `92`
+    — U+005C BACKSLASH (`\`)
+*   `123`
+    — U+007B LEFT CURLY BRACE (`{`)
+*   `125`
+    — U+007D RIGHT CURLY BRACE (`}`)
+
+Also relevant are the content types (see [§ Content types][content-types]).
+This extension is a *text* construct, as it’s parsed alongsides links and such.
+The content inside it (between the braces) is *string*, to support character
+escapes and -references.
+
+Let’s write our extension.
+Add the following code to `index.js`:
+
+```js
+const variableConstruct = {name: 'variable', tokenize: variableTokenize}
+
+export const variables = {text: {123: variableConstruct}}
+
+function variableTokenize(effects, ok, nok) {
+  return start
+
+  function start(code) {
+    console.log('start:', effects, code);
+    return nok(code)
+  }
+}
+```
+
+The above code exports an extension with the identifier `variables`.
+The extension defines a *text* construct for the character code `123`.
+The construct has a `name`, so that it can be turned off (optional, see next
+case), and it has a `tokenize` function that sets up a state machine, which
+receives `effects` and the `ok` and `nok` states.
+`ok` can be used when successful, `nok` when not, and so constructs are a bit
+similar to how promises can *resolve* or *reject*.
+`tokenize` returns the initial state, `start`, which itself receives the current
+character code, prints some debugging information, and then returns a call
+to `nok`.
+
+Ensure that things work by running `node example` and see what it prints.
+
+Now we need to define our states and figure out how variables work.
+Some people prefer sketching a diagram of the flow.
+I often prefer writing it down in pseudo-code prose.
+I’ve also found that test driven development works well, where I write unit
+tests for how it should work, then write the state machine, and finally use a
+code coverage tool to ensure I’ve thought of everything.
+
+In prose, what we have to code looks like this:
+
+*   **start**:
+    Receive `123` as `code`, enter a token for the whole (let’s call it
+    `variable`), enter a token for the marker (`variableMarker`), consume
+    `code`, exit the marker token, enter a token for the contents
+    (`variableString`), switch to *begin*
+*   **begin**:
+    If `code` is `125`, reconsume in *nok*.
+    Else, reconsume in *inside*
+*   **inside**:
+    If `code` is `-5`, `-4`, `-3`, or `null`, reconsume in `nok`.
+    Else, if `code` is `125`, exit the string token, enter a `variableMarker`,
+    consume `code`, exit the marker token, exit the variable token, and switch
+    to *ok*.
+    Else, consume, and remain in *inside*.
+
+That should be it!
+Replace `variableTokenize` with the following to include the needed states:
+
+```js
+function variableTokenize(effects, ok, nok) {
+  return start
+
+  function start(code) {
+    effects.enter('variable')
+    effects.enter('variableMarker')
+    effects.consume(code)
+    effects.exit('variableMarker')
+    effects.enter('variableString')
+    return begin
+  }
+
+  function begin(code) {
+    return code === 125 ? nok(code) : inside(code)
+  }
+
+  function inside(code) {
+    if (code === -5 || code === -4 || code === -3 || code === null) {
+      return nok(code)
+    }
+
+    if (code === 125) {
+      effects.exit('variableString')
+      effects.enter('variableMarker')
+      effects.consume(code)
+      effects.exit('variableMarker')
+      effects.exit('variable')
+      return ok
+    }
+
+    effects.consume(code)
+    return inside
+  }
+}
+```
+
+Run `node example` again and see what it prints!
+The HTML compiler ignores things it doesn’t know, so variables are now removed.
+
+We have our first syntax extension, and it sort of works, but we don’t handle
+character escapes and -references yet.
+We need to do two things to make that work:
+a) skip over `\\` and `\}` in our algorithm,
+b) tell micromark to parse them.
+
+Change the code in `index.js` to support escapes like so:
+
+```diff

+
+Tokens with a `contentType` will be replaced by *postprocess* (see
+[§ Postprocess][postprocess]) by the tokens belonging to that content type.
+
+##### HTML extension
+
+Up next is an HTML extension to replace variables with data.
+Change `example.js` to use one like so:
+
+```diff

++  const html = variablesHtml({planet: '1', 'pla}net': '2'})
++  const out = micromark(buf, {extensions: [variables], htmlExtensions: [html]})
+   console.log(out)
+ }
+```
+
+And add the HTML extension, `variablesHtml`, to `index.js` like so:
+
+```diff
+@@ -52,3 +52,19 @@ function variableTokenize(effects, ok, nok) {
+     return inside(code)
+   }

++export function variablesHtml(data = {}) {

++    var id = this.resume()
++    if (id in data) {
++      this.raw(this.encode(data[id]))
++    }
++  }
++}
+```
+
+`variablesHtml` is a function that receives an object mapping “variables” to
+strings and returns an HTML extension.
+The extension hooks two functions to `variableString`, one when it starts,
+the other when it ends.
+We don’t need to do anything to handle the other tokens as they’re already
+ignored by default.
+`enterVariableString` calls `buffer`, which is a function that “stashes” what
+would otherwise be emitted.
+`exitVariableString` calls `resume`, which is the inverse of `buffer` and
+returns the stashed value.
+If the variable is defined, we ensure it’s made safe (with `this.encode`) and
+finally output that (with `this.raw`).
+
+##### Further exercises
+
+It works!
+We’re done!
+Of course, it can be better, such as with the following potential features:
+
+*   Add support for empty variables
+*   Add support for spaces between markers and string
+*   Add support for line endings in variables
+*   Add support for nested braces
+*   Add support for blocks
+*   Add warnings on undefined variables
+*   Use `micromark-build`, and use `uvu/assert`, `debug`, and
+    `micromark-util-symbol` (see [§ Size & debug][size-debug])
+*   Add [`mdast-util-from-markdown`][from-markdown] and
+    [`mdast-util-to-markdown`][to-markdown] utilities to parse and serialize the
+    AST
+
+#### Case: turn off constructs
+
+Sometimes it’s needed to turn a default construct off.
+That’s possible through a syntax extension.
+Note that not everything can be turned off (such as paragraphs) and even if it’s
+possible to turn something off, it could break micromark (such as character
+escapes).
+
+To disable constructs, refer to them by name in an array at the `disable.null`
+field of an extension:
+
+```js
+import {micromark} from 'micromark'
+
+const extension = {disable: {null: ['codeIndented']}}
+
+console.log(micromark('\ta', {extensions: [extension]}))
+```
+
+Yields:
+
+```html
+
a

+```
+
+## Architecture
+
+micromark is maintained as a monorepo.
+Many of its internals, which are used in `micromark` (core) but also useful for
+developers of extensions or integrations, are available as separate modules.
+Each module maintained here is available in [`packages/`][packages].
+
+### Overview
+
+The naming scheme in [`packages/`][packages] is as follows:
+
+*   `micromark-build`
+    — Small CLI to build dev code into production code
+*   `micromark-core-commonmark`
+    — CommonMark constructs used in micromark
+*   `micromark-factory-*`
+    — Reusable subroutines used to parse parts of constructs
+*   `micromark-util-*`
+    — Reusable helpers often needed when parsing markdown
+*   `micromark`
+    — Core module
+
+micromark has two interfaces: buffering (maintained in
+[`micromark/dev/index.js`](https://github.com/micromark/micromark/blob/main/packages/micromark/dev/index.js))
+and streaming (maintained in
+[`micromark/dev/stream.js`](https://github.com/micromark/micromark/blob/main/packages/micromark/dev/stream.js)).
+The first takes all input at once whereas the last uses a Node.js stream to take
+input separately.
+They thinly wrap how data flows through micromark:
+
+```txt
+                                            micromark
++-----------------------------------------------------------------------------------------------+
+|            +------------+         +-------+         +-------------+         +---------+       |
+| -markdown->+ preprocess +-chunks->+ parse +-events->+ postprocess +-events->+ compile +-html- |
+|            +------------+         +-------+         +-------------+         +---------+       |
++-----------------------------------------------------------------------------------------------+
+```
+
+### Preprocess
+
+The **preprocessor**
+([`micromark/dev/lib/preprocess.js`](https://github.com/micromark/micromark/blob/main/packages/micromark/dev/lib/preprocess.js))
+takes markdown and turns it into chunks.
+
+A **chunk** is either a character code or a slice of a buffer in the form of a
+string.
+Chunks are used because strings are more efficient storage than character codes,
+but limited in what they can represent.
+For example, the input `ab\ncd` is represented as `['ab', -4, 'cd']` in chunks.
+
+A character **code** is often the same as what `String#charCodeAt()` yields but
+micromark adds meaning to certain other values.
+
+In micromark, the actual character U+0009 CHARACTER TABULATION (HT) is replaced
+by one M-0002 HORIZONTAL TAB (HT) and between 0 and 3 M-0001 VIRTUAL SPACE (VS)
+characters, depending on the column at which the tab occurred.
+For example, the input `\ta` is represented as `[-2, -1, -1, -1, 97]` and `a\tb`
+as `[97, -2, -1, -1, 98]` in character codes.
+
+The characters U+000A LINE FEED (LF) and U+000D CARRIAGE RETURN (CR) are
+replaced by virtual characters depending on whether they occur together: M-0003
+CARRIAGE RETURN LINE FEED (CRLF), M-0004 LINE FEED (LF), and M-0005 CARRIAGE
+RETURN (CR).
+For example, the input `a\r\nb\nc\rd` is represented as
+`[97, -5, 98, -4, 99, -3, 100]` in character codes.
+
+The `0` (U+0000 NUL) character code is replaced by U+FFFD REPLACEMENT CHARACTER
+(`�`).
+
+The `null` code represents the end of the input stream (called *eof* for end of
+file).
+
+### Parse
+
+The **parser**
+([`micromark/dev/lib/parse.js`](https://github.com/micromark/micromark/blob/main/packages/micromark/dev/lib/parse.js))
+takes chunks and turns them into events.
+
+An **event** is the start or end of a token amongst other events.
+Tokens can “contain” other tokens, even though they are stored in a flat list,
+by entering before and exiting after them.
+
+A **token** is a span of one or more codes.
+Tokens are most of what micromark produces: the built in HTML compiler or other
+tools can turn them into different things.
+Tokens are essentially names attached to a slice, such as `lineEndingBlank` for
+certain line endings, or `codeFenced` for a whole fenced code.
+
+Sometimes, more info is attached to tokens, such as `_open` and `_close` by
+`attention` (strong, emphasis) to signal whether the sequence can open or close
+an attention run.
+These fields have to do with how the parser works, which is complex and not
+always pretty.
+
+Certain fields (`previous`, `next`, and `contentType`) are used in many cases:
+linked tokens for subcontent.
+Linked tokens are used because outer constructs are parsed first.
+Take for example:
+
+```markdown
+- *a
+  b*.
+```
+
+1.  The list marker and the space after it is parsed first
+2.  The rest of the line is a `chunkFlow` token
+3.  The two spaces on the second line are a `linePrefix` of the list
+4.  The rest of the line is another `chunkFlow` token
+
+The two `chunkFlow` tokens are linked together and the chunks they span are
+passed through the flow tokenizer.
+There the chunks are seen as `chunkContent` and passed through the content
+tokenizer.
+There the chunks are seen as a paragraph and seen as `chunkText` and passed
+through the text tokenizer.
+Finally, the attention (emphasis) and data (“raw” characters) is parsed there,
+and we’re done!
+
+#### Content types
+
+The parser starts out with a document tokenizer.
+*Document* is the top-most content type, which includes containers such as block
+quotes and lists.
+Containers in markdown come from the margin and include more constructs
+on the lines that define them.
+
+*Flow* represents the sections (block constructs such as ATX and setext
+headings, HTML, indented and fenced code, thematic breaks), which like
+*document* are also parsed per line.
+An example is HTML, which has a certain starting condition (such as `
+```
+
+## Use
+
+Say we have the following module `example.js`:
+
+```js
+import {unified} from 'unified'
+import remarkParse from 'remark-parse'
+import remarkGfm from 'remark-gfm'
+import remarkRehype from 'remark-rehype'
+import rehypeStringify from 'rehype-stringify'
+
+main()
+
+async function main() {
+  const file = await unified()
+    .use(remarkParse)
+    .use(remarkGfm)
+    .use(remarkRehype)
+    .use(rehypeStringify)
+    .process('# Hi\n\n*Hello*, world!')
+
+  console.log(String(file))
+}
+```
+
+Running that with `node example.js` yields:
+
+```html
+
Hi

+
Hello, world!

+```
+
+## API
+
+This package exports no identifiers.
+The default export is `remarkParse`.
+
+### `unified().use(remarkParse)`
+
+Add support for parsing markdown input.
+There are no options.
+
+## Examples
+
+### Example: support GFM and frontmatter
+
+We support CommonMark by default.
+Non-standard markdown extensions can be enabled with plugins.
+The following example adds support for GFM features (autolink literals,
+footnotes, strikethrough, tables, tasklists) and frontmatter (YAML):
+
+```js
+import {unified} from 'unified'
+import remarkParse from 'remark-parse'
+import remarkFrontmatter from 'remark-frontmatter'
+import remarkGfm from 'remark-gfm'
+import remarkRehype from 'remark-rehype'
+import rehypeStringify from 'rehype-stringify'
+
+main()
+
+async function main() {
+  const file = await unified()
+    .use(remarkParse)
+    .use(remarkFrontmatter)
+    .use(remarkGfm)
+    .use(remarkRehype)
+    .use(rehypeStringify)
+    .process('---\nlayout: home\n---\n\n# Hi ~~Mars~~Venus!')
+
+  console.log(String(file))
+}
+```
+
+Yields:
+
+```html
+
Hi MarsVenus!

+```
+
+### Example: turning markdown into a man page
+
+Man pages (short for manual pages) are a way to document CLIs (example: type
+`man git-log` in your terminal).
+They use an old markup format called roff.
+There’s a remark plugin, [`remark-man`][remark-man], that can serialize as roff.
+The following example turns markdown into man pages by using unified with
+`remark-parse` and `remark-man`:
+
+```js
+import {unified} from 'unified'
+import remarkParse from 'remark-parse'
+import remarkMan from 'remark-man'
+
+main()
+
+async function main() {
+  const file = await unified()
+    .use(remarkParse)
+    .use(remarkMan)
+    .process('# titan(7) -- largest moon of saturn\n\nTitan is the largest moon…')
+
+  console.log(String(file))
+}
+```
+
+Yields:
+
+```roff
+.TH "TITAN" "7" "November 2021" "" ""
+.SH "NAME"
+\fBtitan\fR - largest moon of saturn
+.P
+Titan is the largest moon…
+```
+
+## Syntax
+
+Markdown is parsed according to CommonMark.
+Other plugins can add support for syntax extensions.
+If you’re interested in extending markdown,
+[more information is available in micromark’s readme][micromark-extend].
+
+## Syntax tree
+
+The syntax tree format used in remark is [mdast][].
+
+## Types
+
+This package is fully typed with [TypeScript][].
+There are no extra exported types.
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with all maintained
+versions of Node.js.
+As of now, that is Node.js 12.20+, 14.14+, and 16.0+.
+Our projects sometimes work with older versions, but this is not guaranteed.
+
+## Security
+
+As markdown can be turned into HTML and improper use of HTML can open you up to
+[cross-site scripting (XSS)][xss] attacks, use of remark can be unsafe.
+When going to HTML, you will likely combine remark with **[rehype][]**, in which
+case you should use [`rehype-sanitize`][rehype-sanitize].
+
+Use of remark plugins could also open you up to other attacks.
+Carefully assess each plugin and the risks involved in using them.

+
+## What is this?
+
+This package is a [unified][] ([remark][]) plugin that defines how to take a
+syntax tree as input and turn it into serialized markdown.
+
+This plugin is built on [`mdast-util-to-markdown`][mdast-util-to-markdown],
+which turns [mdast][] syntax trees into a string.
+remark focusses on making it easier to transform content by abstracting such
+internals away.
+
+**unified** is a project that transforms content with abstract syntax trees
+(ASTs).
+**remark** adds support for markdown to unified.
+**mdast** is the markdown AST that remark uses.
+This is a remark plugin that defines how mdast is turned into markdown.
+
+## When should I use this?
+
+This plugin adds support to unified for serializing markdown.
+You can alternatively use [`remark`][remark-core] instead, which combines
+unified, [`remark-parse`][remark-parse], and this plugin.
+
+You can combine this plugin with other plugins to add syntax extensions.
+Notable examples that deeply integrate with it are
+[`remark-gfm`][remark-gfm],
+[`remark-mdx`][remark-mdx],
+[`remark-frontmatter`][remark-frontmatter],
+[`remark-math`][remark-math], and
+[`remark-directive`][remark-directive].
+You can also use any other [remark plugin][plugin] before `remark-stringify`.
+
+If you want to handle syntax trees manually, you can use
+[`mdast-util-to-markdown`][mdast-util-to-markdown].
+
+## Install
+
+This package is [ESM only](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c).
+In Node.js (version 12.20+, 14.14+, or 16.0+), install with [npm][]:
+
+```sh
+npm install remark-stringify
+```
+
+In Deno with [Skypack][]:
+
+```js
+import remarkStringify from 'https://cdn.skypack.dev/remark-stringify@10?dts'
+```
+
+In browsers with [Skypack][]:
+
+```html
+
+```
+
+## Use
+
+Say we have the following module `example.js`:
+
+```js
+import {unified} from 'unified'
+import rehypeParse from 'rehype-parse'
+import rehypeRemark from 'rehype-remark'
+import remarkStringify from 'remark-stringify'
+
+main()
+
+async function main() {
+  const file = await unified()
+    .use(rehypeParse)
+    .use(rehypeRemark)
+    .use(remarkStringify, {
+      bullet: '*',
+      fence: '~',
+      fences: true,
+      incrementListMarker: false
+    })
+    .process('
Hello, world!
')
+
+  console.log(String(file))
+}
+```
+
+Running that with `node example.js` yields:
+
+```markdown
+# Hello, world!
+```
+
+## API
+
+This package exports no identifiers.
+The default export is `remarkStringify`.
+
+### `unified().use(remarkStringify[, options])`
+
+Add support for serializing markdown.
+Options are passed to [`mdast-util-to-markdown`][mdast-util-to-markdown]:
+all formatting options are supported.
+
+##### `options`
+
+Configuration (optional).
+
+###### `options.bullet`
+
+Marker to use for bullets of items in unordered lists (`'*'`, `'+'`, or `'-'`,
+default: `'*'`).
+
+###### `options.bulletOther`
+
+Marker to use in certain cases where the primary bullet doesn’t work (`'*'`,
+`'+'`, or `'-'`, default: depends).
+See [`mdast-util-to-markdown`][mdast-util-to-markdown] for more information.
+
+###### `options.bulletOrdered`
+
+Marker to use for bullets of items in ordered lists (`'.'` or `')'`, default:
+`'.'`).
+
+###### `options.bulletOrderedOther`
+
+Marker to use in certain cases where the primary bullet for ordered items
+doesn’t work (`'.'` or `')'`, default: none).
+See [`mdast-util-to-markdown`][mdast-util-to-markdown] for more information.
+
+###### `options.closeAtx`
+
+Whether to add the same number of number signs (`#`) at the end of an ATX
+heading as the opening sequence (`boolean`, default: `false`).
+
+###### `options.emphasis`
+
+Marker to use for emphasis (`'*'` or `'_'`, default: `'*'`).
+
+###### `options.fence`
+
+Marker to use for fenced code (``'`'`` or `'~'`, default: ``'`'``).
+
+###### `options.fences`
+
+Whether to use fenced code always (`boolean`, default: `false`).
+The default is to use fenced code if there is a language defined, if the code is
+empty, or if it starts or ends in blank lines.
+
+###### `options.incrementListMarker`
+
+Whether to increment the counter of ordered lists items (`boolean`, default:
+`true`).
+
+###### `options.listItemIndent`
+
+How to indent the content of list items (`'one'`, `'tab'`, or `'mixed'`,
+default: `'tab'`).
+Either with the size of the bullet plus one space (when `'one'`), a tab stop
+(`'tab'`), or depending on the item and its parent list (`'mixed'`, uses `'one'`
+if the item and list are tight and `'tab'` otherwise).
+
+###### `options.quote`
+
+Marker to use for titles (`'"'` or `"'"`, default: `'"'`).
+
+###### `options.resourceLink`
+
+Whether to always use resource links (`boolean`, default: `false`).
+The default is to use autolinks (``) when possible
+and resource links (`[text](url)`) otherwise.
+
+###### `options.rule`
+
+Marker to use for thematic breaks (`'*'`, `'-'`, or `'_'`, default: `'*'`).
+
+###### `options.ruleRepetition`
+
+Number of markers to use for thematic breaks (`number`, default:
+`3`, min: `3`).
+
+###### `options.ruleSpaces`
+
+Whether to add spaces between markers in thematic breaks (`boolean`, default:
+`false`).
+
+###### `options.setext`
+
+Whether to use setext headings when possible (`boolean`, default: `false`).
+The default is to always use ATX headings (`# heading`) instead of setext
+headings (`heading\n=======`).
+Setext headings can’t be used for empty headings or headings with a rank of
+three or more.
+
+###### `options.strong`
+
+Marker to use for strong (`'*'` or `'_'`, default: `'*'`).
+
+###### `options.tightDefinitions`
+
+Whether to join definitions without a blank line (`boolean`, default: `false`).
+The default is to add blank lines between any flow (“block”) construct.
+
+###### `options.handlers`
+
+This option is a bit advanced as it requires knowledge of ASTs, so we defer
+to the documentation available in
+[`mdast-util-to-markdown`][mdast-util-to-markdown].
+
+###### `options.join`
+
+This option is a bit advanced as it requires knowledge of ASTs, so we defer
+to the documentation available in
+[`mdast-util-to-markdown`][mdast-util-to-markdown].
+
+###### `options.unsafe`
+
+This option is a bit advanced as it requires deep knowledge of markdown, so we
+defer to the documentation available in
+[`mdast-util-to-markdown`][mdast-util-to-markdown].
+
+## Syntax
+
+Markdown is serialized according to CommonMark but care is taken to format in
+such a way that the resulting markdown should work with most markdown parsers.
+Other plugins can add support for syntax extensions.
+
+## Syntax tree
+
+The syntax tree format used in remark is [mdast][].
+
+## Types
+
+This package is fully typed with [TypeScript][].
+An `Options` type is exported, which models the interface of accepted options.
+
+## Security
+
+As markdown can be turned into HTML and improper use of HTML can open you up to
+[cross-site scripting (XSS)][xss] attacks, use of remark can be unsafe.
+When going to HTML, you will likely combine remark with **[rehype][]**, in which
+case you should use [`rehype-sanitize`][rehype-sanitize].
+
+Use of remark plugins could also open you up to other attacks.
+Carefully assess each plugin and the risks involved in using them.

+
+## What is this?
+
+This package is a [unified][] processor with support for parsing markdown input
+and serializing markdown as output by using unified with
+[`remark-parse`][remark-parse] and [`remark-stringify`][remark-stringify].
+
+**unified** is a project that transforms content with abstract syntax trees
+(ASTs).
+**remark** adds support for markdown to unified.
+**mdast** is the markdown AST that remark uses.
+Please see [the monorepo readme][remark] for what the remark ecosystem is.
+
+## When should I use this?
+
+You can use this package when you want to use unified, have markdown as input,
+and want markdown as output.
+This package is a shortcut for
+`unified().use(remarkParse).use(remarkStringify)`.
+When the input isn’t markdown (meaning you don’t need `remark-parse`) or the
+output is not markdown (you don’t need `remark-stringify`), it’s recommended to
+use unified directly.
+
+When you want to inspect and format markdown files in a project on the command
+line, you can use [`remark-cli`][remark-cli].
+
+## Install
+
+This package is [ESM only](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c).
+In Node.js (version 12.20+, 14.14+, or 16.0+), install with [npm][]:
+
+```sh
+npm install remark
+```
+
+In Deno with [Skypack][]:
+
+```js
+import {remark} from 'https://cdn.skypack.dev/remark@14?dts'
+```
+
+In browsers with [Skypack][]:
+
+```html
+
+```
+
+## Use
+
+Say we have the following module `example.js`:
+
+```js
+import {remark} from 'remark'
+import remarkGfm from 'remark-gfm'
+import remarkToc from 'remark-toc'
+
+main()
+
+async function main() {
+  const file = await remark()
+    .use(remarkGfm)
+    .use(remarkToc)
+    .process('# Hi\n\n## Table of contents\n\n## Hello\n\n*Some* ~more~ _things_.')
+
+  console.error(String(file))
+}
+```
+
+Running that with `node example.js` yields:
+
+```markdown
+# Hi
+
+## Table of contents
+
+*   [Hello](#hello)
+
+## Hello
+
+*Some* ~~more~~ *things*.
+```
+
+## API
+
+This package exports the following identifier: `remark`.
+There is no default export.
+
+### `remark()`
+
+Create a new (unfrozen) unified processor that already uses `remark-parse` and
+`remark-stringify` and you can add more plugins to.
+See [`unified`][unified] for more information.
+
+## Examples
+
+### Example: checking markdown
+
+The following example checks that markdown code style is consistent and follows
+some best practices:
+
+```js
+import {reporter} from 'vfile-reporter'
+import {remark} from 'remark'
+import remarkPresetLintConsistent from 'remark-preset-lint-consistent'
+import remarkPresetLintRecommended from 'remark-preset-lint-recommended'
+
+main()
+
+async function main() {
+  const file = await remark()
+    .use(remarkPresetLintConsistent)
+    .use(remarkPresetLintRecommended)
+    .process('1) Hello, _Jupiter_ and *Neptune*!')
+
+  console.error(reporter(file))
+}
+```
+
+Yields:
+
+```txt
+        1:1  warning  Missing newline character at end of file  final-newline              remark-lint
+   1:1-1:35  warning  Marker style should be `.`                ordered-list-marker-style  remark-lint
+        1:4  warning  Incorrect list-item indent: add 1 space   list-item-indent           remark-lint
+  1:25-1:34  warning  Emphasis should use `_` as a marker       emphasis-marker            remark-lint
+
+⚠ 4 warnings
+```
+
+### Example: passing options to `remark-stringify`
+
+When you use `remark-stringify` manually you can pass options to `use`.
+Because `remark-stringify` is already used in `remark`, that’s not possible.
+To define options for `remark-stringify`, you can instead pass options to
+`data`:
+
+```js
+import {remark} from 'remark'
+
+main()
+
+async function main() {
+  const file = await remark()
+    .data('settings', {bullet: '*', setext: true, listItemIndent: 'one'})
+    .process('# Moons of Neptune\n\n- Naiad\n- Thalassa\n- Despine\n- …')
+
+  console.log(String(file))
+}
+```
+
+Yields:
+
+```markdown
+Moons of Neptune
+================
+
+* Naiad
+* Thalassa
+* Despine
+* …
+```
+
+## Syntax
+
+Markdown is parsed and serialized according to CommonMark.
+Other plugins can add support for syntax extensions.
+
+## Syntax tree
+
+The syntax tree format used in remark is [mdast][].
+
+## Types
+
+This package is fully typed with [TypeScript][].
+There are no extra exported types.
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with all maintained
+versions of Node.js.
+As of now, that is Node.js 12.20+, 14.14+, and 16.0+.
+Our projects sometimes work with older versions, but this is not guaranteed.
+
+## Security
+
+As markdown can be turned into HTML and improper use of HTML can open you up to
+[cross-site scripting (XSS)][xss] attacks, use of remark can be unsafe.
+When going to HTML, you will likely combine remark with **[rehype][]**, in which
+case you should use [`rehype-sanitize`][rehype-sanitize].
+
+Use of remark plugins could also open you up to other attacks.
+Carefully assess each plugin and the risks involved in using them.
+

+[![Build Status](https://travis-ci.org/isaacs/rimraf.svg?branch=master)](https://travis-ci.org/isaacs/rimraf) [![Dependency Status](https://david-dm.org/isaacs/rimraf.svg)](https://david-dm.org/isaacs/rimraf) [![devDependency Status](https://david-dm.org/isaacs/rimraf/dev-status.svg)](https://david-dm.org/isaacs/rimraf#info=devDependencies)
+
+The [UNIX command](http://en.wikipedia.org/wiki/Rm_(Unix)) `rm -rf` for node.
+
+Install with `npm install rimraf`, or just drop rimraf.js somewhere.
+
+## API
+
+`rimraf(f, [opts], callback)`
+
+The first parameter will be interpreted as a globbing pattern for files. If you
+want to disable globbing you can do so with `opts.disableGlob` (defaults to
+`false`). This might be handy, for instance, if you have filenames that contain
+globbing wildcard characters.
+
+The callback will be called with an error if there is one.  Certain
+errors are handled for you:
+
+* Windows: `EBUSY` and `ENOTEMPTY` - rimraf will back off a maximum of
+  `opts.maxBusyTries` times before giving up, adding 100ms of wait
+  between each attempt.  The default `maxBusyTries` is 3.
+* `ENOENT` - If the file doesn't exist, rimraf will return
+  successfully, since your desired outcome is already the case.
+* `EMFILE` - Since `readdir` requires opening a file descriptor, it's
+  possible to hit `EMFILE` if too many file descriptors are in use.
+  In the sync case, there's nothing to be done for this.  But in the
+  async case, rimraf will gradually back off with timeouts up to
+  `opts.emfileWait` ms, which defaults to 1000.
+
+## options
+
+* unlink, chmod, stat, lstat, rmdir, readdir,
+  unlinkSync, chmodSync, statSync, lstatSync, rmdirSync, readdirSync
+
+    In order to use a custom file system library, you can override
+    specific fs functions on the options object.
+
+    If any of these functions are present on the options object, then
+    the supplied function will be used instead of the default fs
+    method.
+
+    Sync methods are only relevant for `rimraf.sync()`, of course.
+
+    For example:
+
+    ```javascript
+    var myCustomFS = require('some-custom-fs')
+
+    rimraf('some-thing', myCustomFS, callback)
+    ```
+
+* maxBusyTries
+
+    If an `EBUSY`, `ENOTEMPTY`, or `EPERM` error code is encountered
+    on Windows systems, then rimraf will retry with a linear backoff
+    wait of 100ms longer on each try.  The default maxBusyTries is 3.
+
+    Only relevant for async usage.
+
+* emfileWait
+
+    If an `EMFILE` error is encountered, then rimraf will retry
+    repeatedly with a linear backoff of 1ms longer on each try, until
+    the timeout counter hits this max.  The default limit is 1000.
+
+    If you repeatedly encounter `EMFILE` errors, then consider using
+    [graceful-fs](http://npm.im/graceful-fs) in your program.
+
+    Only relevant for async usage.
+
+* glob
+
+    Set to `false` to disable [glob](http://npm.im/glob) pattern
+    matching.
+
+    Set to an object to pass options to the glob module.  The default
+    glob options are `{ nosort: true, silent: true }`.
+
+    Glob version 6 is used in this module.
+
+    Relevant for both sync and async usage.
+
+* disableGlob
+
+    Set to any non-falsey value to disable globbing entirely.
+    (Equivalent to setting `glob: false`.)
+
+## rimraf.sync
+
+It can remove stuff synchronously, too.  But that's not so good.  Use
+the async API.  It's better.
+
+## CLI
+
+If installed with `npm install rimraf -g` it can be used as a global
+command `rimraf  [ ...]` which is useful for cross platform support.
+
+## mkdirp
+
+If you need to create a directory recursively, check out
+[mkdirp](https://github.com/substack/node-mkdirp).

+# sade [![Build Status](https://travis-ci.org/lukeed/sade.svg?branch=master)](https://travis-ci.org/lukeed/sade)
+
+> Smooth (CLI) Operator 🎶
+
+Sade is a small but powerful tool for building command-line interface (CLI) applications for Node.js that are fast, responsive, and helpful!
+
+It enables default commands, git-like subcommands, option flags with aliases, default option values with type-casting, required-vs-optional argument handling, command validation, and automated help text generation!
+
+Your app's UX will be as smooth as butter... just like [Sade's voice](https://www.youtube.com/watch?v=4TYv2PhG89A). 😉
+
+
+## Install
+
+```
+$ npm install --save sade
+```
+
+
+## Usage
+
+***Input:***
+
+```js
+#!/usr/bin/env node
+
+const sade = require('sade');
+
+const prog = sade('my-cli');
+
+prog
+  .version('1.0.5')
+  .option('--global, -g', 'An example global flag')
+  .option('-c, --config', 'Provide path to custom config', 'foo.config.js');
+
+prog
+  .command('build  ')
+  .describe('Build the source directory. Expects an `index.js` entry file.')
+  .option('-o, --output', 'Change the name of the output file', 'bundle.js')
+  .example('build src build --global --config my-conf.js')
+  .example('build app public -o main.js')
+  .action((src, dest, opts) => {
+    console.log(`> building from ${src} to ${dest}`);
+    console.log('> these are extra opts', opts);
+  });
+
+prog.parse(process.argv);
+```
+
+***Output:***
+
+```a
+$ my-cli --help
+
+  Usage
+    $ my-cli  [options]
+
+  Available Commands
+    build    Build the source directory.
+
+  For more info, run any command with the `--help` flag
+    $ my-cli build --help
+
+  Options
+    -v, --version    Displays current version
+    -g, --global     An example global flag
+    -c, --config     Provide path to custom config  (default foo.config.js)
+    -h, --help       Displays this message
+
+
+$ my-cli build --help
+
+  Description
+    Build the source directory.
+    Expects an `index.js` entry file.
+
+  Usage
+    $ my-cli build  [options]
+
+  Options
+    -o, --output    Change the name of the output file  (default bundle.js)
+    -g, --global    An example global flag
+    -c, --config    Provide path to custom config  (default foo.config.js)
+    -h, --help      Displays this message
+
+  Examples
+    $ my-cli build src build --global --config my-conf.js
+    $ my-cli build app public -o main.js
+```
+
+## Tips
+
+- **Define your global/program-wide version, options, description, and/or examples first.**

+  _Once you define a Command, you can't access the global-scope again._
+
+- **Define all commands & options in the order that you want them to appear.**

+  _Sade will not mutate or sort your CLI for you. Global options print before local options._
+
+- **Required arguments without values will error & exit**

+  _An `Insufficient arguments!` error will be displayed along with a help prompt._
+
+- **Don't worry about manually displaying help~!**

+  _Your help text is displayed automatically... including command-specific help text!_
+
+- **Automatic default/basic patterns**

+  _Usage text will always append `[options]` & `--help` and `--version` are done for you._
+
+- **Only define what you want to display!**

+  _Help text sections (example, options, etc) will only display if you provide values._
+
+
+## Subcommands
+
+Subcommands are defined & parsed like any other command! When defining their [`usage`](#usage-1), everything up until the first argument (`[foo]` or ``) is interpreted as the command string.
+
+They should be defined in the order that you want them to appear in your general `--help` output.
+
+Lastly, it is _not_ necessary to define the subcommand's "base" as an additional command. However, if you choose to do so, it's recommended that you define it first for better visibility.
+
+```js
+const prog = sade('git');
+
+// Not necessary for subcommands to work, but it's here anyway!
+prog
+  .command('remote')
+  .describe('Manage set of tracked repositories')
+  .action(opts => {
+    console.log('~> Print current remotes...');
+  });
+
+prog
+  .command('remote add  ', 'Demo...')
+  .action((name, url, opts) => {
+    console.log(`~> Adding a new remote (${name}) to ${url}`);
+  });
+
+prog
+  .command('remote rename  ', 'Demo...')
+  .action((old, nxt, opts) => {
+    console.log(`~> Renaming from ${old} to ${nxt}~!`);
+  });
+```
+
+
+## Single Command Mode
+
+In certain circumstances, you may only need `sade` for a single-command CLI application.
+
+> **Note:** Until `v1.6.0`, this made for an awkward pairing.
+
+To enable this, you may make use of the [`isSingle`](#issingle) argument. Doing so allows you to pass the program's entire [`usage` text](#usage-1) into the `name` argument.
+
+With "Single Command Mode" enabled, your entire binary operates as one command. This means that any [`prog.command`](#progcommandusage-desc-opts) calls are disallowed & will instead throw an Error. Of course, you may still define a program version, a description, an example or two, and declare options. You are customizing the program's attributes as a whole.*
+
+> * This is true for multi-command applications, too, up until your first `prog.command()` call!
+
+***Example***
+
+Let's reconstruct [`sirv-cli`](https://github.com/lukeed/sirv), which is a single-command application that (optionally) accepts a directory from which to serve files. It also offers a slew of option flags:
+
+```js
+sade('sirv [dir]', true)
+  .version('1.0.0')
+  .describe('Run a static file server')
+  .example('public -qeim 31536000')
+  .example('--port 8080 --etag')
+  .example('my-app --dev')
+  .option('-D, --dev', 'Enable "dev" mode')
+  .option('-e, --etag', 'Enable "Etag" header')
+  // There are a lot...
+  .option('-H, --host', 'Hostname to bind', 'localhost')
+  .option('-p, --port', 'Port to bind', 5000)
+  .action((dir, opts) => {
+    // Program handler
+  })
+  .parse(process.argv);
+```
+
+When `sirv --help` is run, the generated help text is trimmed, fully aware that there's only one command in this program:
+
+```
+  Description
+    Run a static file server
+
+  Usage
+    $ sirv [dir] [options]
+
+  Options
+    -D, --dev        Enable "dev" mode
+    -e, --etag       Enable "Etag" header
+    -H, --host       Hostname to bind  (default localhost)
+    -p, --port       Port to bind  (default 5000)
+    -v, --version    Displays current version
+    -h, --help       Displays this message
+
+  Examples
+    $ sirv public -qeim 31536000
+    $ sirv --port 8080 --etag
+    $ sirv my-app --dev
+```
+
+## Command Aliases
+
+Command aliases are alternative names (aliases) for a command. They are often used as shortcuts or as typo relief!
+
+The aliased names do not appear in the general help text.

+Instead, they only appear within the Command-specific help text under an "Aliases" section.
+
+***Limitations***
+
+* You cannot assign aliases while in [Single Command Mode](#single-command-mode)
+* You cannot call [`prog.alias()`](#progaliasnames) before defining any Commands (via `prog.commmand()`)
+* You, the developer, must keep track of which aliases have already been used and/or exist as Command names
+
+***Example***
+
+Let's reconstruct the `npm install` command as a Sade program:
+
+```js
+sade('npm')
+  // ...
+  .command('install [package]', 'Install a package', {
+    alias: ['i', 'add', 'isntall']
+  })
+  .option('-P, --save-prod', 'Package will appear in your dependencies.')
+  .option('-D, --save-dev', 'Package will appear in your devDependencies.')
+  .option('-O, --save-optional', 'Package will appear in your optionalDependencies')
+  .option('-E, --save-exact', 'Save exact versions instead of using a semver range operator')
+  // ...
+```
+
+When we run `npm --help` we'll see this general help text:
+
+```
+  Usage
+    $ npm  [options]
+
+  Available Commands
+    install    Install a package
+
+  For more info, run any command with the `--help` flag
+    $ npm install --help
+
+  Options
+    -v, --version    Displays current version
+    -h, --help       Displays this message
+```
+
+When we run `npm install --help` — ***or*** the help flag with any of `install`'s aliases — we'll see this command-specific help text:
+
+```
+  Description
+    Install a package
+
+  Usage
+    $ npm install [package] [options]
+
+  Aliases
+    $ npm i
+    $ npm add
+    $ npm isntall
+
+  Options
+    -P, --save-prod        Package will appear in your dependencies.
+    -D, --save-dev         Package will appear in your devDependencies.
+    -O, --save-optional    Package will appear in your optionalDependencies
+    -E, --save-exact       Save exact versions instead of using a semver range operator
+    -h, --help             Displays this message
+```
+
+
+
+## API
+
+### sade(name, isSingle)
+Returns: `Program`
+
+Returns your chainable Sade instance, aka your `Program`.
+
+#### name
+Type: `String`

+Required: `true`
+
+The name of your `Program` / binary application.
+
+#### isSingle
+Type: `Boolean`

+Default: `name.includes(' ');`
+
+If your `Program` is meant to have ***only one command***.

+When `true`, this simplifies your generated `--help` output such that:
+
+* the "root-level help" is your _only_ help text
+* the "root-level help" does not display an `Available Commands` section
+* the "root-level help" does not inject `$ name ` into the `Usage` section
+* the "root-level help" does not display `For more info, run any command with the `--help` flag` text
+
+You may customize the `Usage` of your command by modifying the `name` argument directly.

+Please read [Single Command Mode](#single-command-mode) for an example and more information.
+
+> **Important:** Whenever `name` includes a custom usage, then `isSingle` is automatically assumed and enforced!
+
+### prog.command(usage, desc, opts)
+
+Create a new Command for your Program. This changes the current state of your Program.
+
+All configuration methods (`prog.describe`, `prog.action`, etc) will apply to this Command until another Command has been created!
+
+#### usage
+
+Type: `String`
+
+The usage pattern for your current Command. This will be included in the general or command-specific `--help` output.
+
+_Required_ arguments are wrapped with `<` and `>` characters; for example, `` and ``.
+
+_Optional_ arguments are wrapped with `[` and `]` characters; for example, `[foo]` and `[bar]`.
+
+All arguments are ***positionally important***, which means they are passed to your current Command's [`handler`](#handler) function in the order that they were defined.
+
+When optional arguments are defined but don't receive a value, their positionally-equivalent function parameter will be `undefined`.
+
+> **Important:** You **must** define & expect required arguments _before_ optional arguments!
+
+```js
+sade('foo')
+
+  .command('greet  ')
+  .action((adjective, noun, opts) => {
+    console.log(`Hello, ${adjective} ${noun}!`);
+  })
+
+  .command('drive  [color] [speed]')
+  .action((vehicle, color, speed, opts) => {
+    let arr = ['Driving my'];
+    arr.push(color ? `${color} ${vehicle}` : vehicle);
+    speed && arr.push(`at ${speed}`);
+    opts.yolo && arr.push('...YOLO!!');
+    let str = arr.join(' ');
+    console.log(str);
+  });
+```
+
+```sh
+$ foo greet beautiful person
+# //=> Hello, beautiful person!
+
+$ foo drive car
+# //=> Driving my car
+
+$ foo drive car red
+# //=> Driving my red card
+
+$ foo drive car blue 100mph --yolo
+# //=> Driving my blue car at 100mph ...YOLO!!
+```
+
+
+#### desc
+
+Type: `String`

+Default: `''`
+
+The Command's description. The value is passed directly to [`prog.describe`](#progdescribetext).
+
+#### opts
+
+Type: `Object`

+Default: `{}`
+
+##### opts.alias
+Type: `String|Array`
+
+Optionally define one or more aliases for the current Command.

+When declared, the `opts.alias` value is passed _directly_ to the [`prog.alias`](#progaliasnames) method.
+
+```js
+// Program A is equivalent to Program B
+// ---
+
+const A = sade('bin')
+  .command('build', 'My build command', { alias: 'b' })
+  .command('watch', 'My watch command', { alias: ['w', 'dev'] });
+
+const B = sade('bin')
+  .command('build', 'My build command').alias('b')
+  .command('watch', 'My watch command').alias('w', 'dev');
+```
+
+
+##### opts.default
+
+Type: `Boolean`
+
+Manually set/force the current Command to be the Program's default command. This ensures that the current Command will run if no command was specified.
+
+> **Important:** If you run your Program without a Command _and_ without specifying a default command, your Program will exit with a `No command specified` error.
+
+```js
+const prog = sade('greet');
+
+prog.command('hello');
+//=> only runs if :: `$ greet hello`
+
+// $ greet
+//=> error: No command specified.
+
+prog.command('howdy', '', { default:true });
+//=> runs as `$ greet` OR `$ greet howdy`
+
+// $ greet
+//=> runs 'howdy' handler
+
+// $ greet foobar
+//=> error: Invalid command
+```
+
+
+### prog.describe(text)
+
+Add a description to the current Command.
+
+#### text
+
+Type: `String|Array`
+
+The description text for the current Command. This will be included in the general or command-specific `--help` output.
+
+Internally, your description will be separated into an `Array` of sentences.
+
+For general `--help` output, ***only*** the first sentence will be displayed. However, **all sentences** will be printed for command-specific `--help` text.
+
+> **Note:** Pass an `Array` if you don't want internal assumptions. However, the first item is _always_ displayed in general help, so it's recommended to keep it short.
+
+
+### prog.alias(...names)
+
+Define one or more aliases for the current Command.
+
+> **Important:** An error will be thrown if:
1) the program is in [Single Command Mode](#single-command-mode); or
2) `prog.alias` is called before any `prog.command`.
+
+#### names
+
+Type: `String`
+
+The list of alternative names (aliases) for the current Command.

+For example, you may want to define shortcuts and/or common typos for the Command's full name.
+
+> **Important:** Sade _does not_ check if the incoming `names` are already in use by other Commands or their aliases.
During conflicts, the Command with the same `name` is given priority, otherwise the first Command (according to Program order) with `name` as an alias is chosen.
+
+The `prog.alias()` is append-only, so calling it multiple times within a Command context will _keep_ all aliases, including those initially passed via [`opts.alias`](#optsdefault).
+
+```js
+sade('bin')
+  .command('hello ', 'Greet someone by their name', {
+    alias: ['hey', 'yo']
+  })
+  .alias('hi', 'howdy')
+  .alias('hola', 'oi');
+//=> hello aliases: hey, yo, hi, howdy, hola, oi
+```
+
+
+### prog.action(handler)
+
+Attach a callback to the current Command.
+
+#### handler
+
+Type: `Function`
+
+The function to run when the current Command is executed.
+
+Its parameters are based (positionally) on your Command's [`usage`](#usage-1) definition.
+
+All options, flags, and extra/unknown values are included as the last parameter.
+
+> **Note:** Optional arguments are also passed as parameters & may be `undefined`!
+
+```js
+sade('foo')
+  .command('cp  ')
+  .option('-f, --force', 'Overwrite without confirmation')
+  .option('-c, --clone-dir', 'Copy files to additional directory')
+  .option('-v, --verbose', 'Enable verbose output')
+  .action((src, dest, opts) => {
+    console.log(`Copying files from ${src} --> ${dest}`);
+    opts.c && console.log(`ALSO copying files from ${src} --> ${opts['clone-dir']}`);
+    console.log('My options:', opts);
+  })
+
+// $ foo cp original my-copy -v
+//=> Copying files from original --> my-copy
+//=> My options: { _:[], v:true, verbose:true }
+
+// $ foo cp original my-copy --clone-dir my-backup
+//=> Copying files from original --> my-copy
+//=> ALSO copying files from original --> my-backup
+//=> My options: { _:[], c:'my-backup', 'clone-dir':'my-backup' }
+```
+
+
+### prog.example(str)
+
+Add an example for the current Command.
+
+#### str
+
+Type: `String`
+
+The example string to add. This will be included in the general or command-specific `--help` output.
+
+> **Note:** Your example's `str` will be prefixed with your Program's [`name`](#sadename).
+
+
+### prog.option(flags, desc, value)
+
+Add an Option to the current Command.
+
+#### flags
+
+Type: `String`
+
+The Option's flags, which may optionally include an alias.
+
+You may use a comma (`,`) or a space (` `) to separate the flags.
+
+> **Note:** The short & long flags can be declared in any order. However, the alias will always be displayed first.
+
+> **Important:** If using hyphenated flag names, they will be accessible **as declared** within your [`action()`](#progactionhandler) handler!
+
+```js
+prog.option('--global'); // no alias
+prog.option('-g, --global'); // alias first, comma
+prog.option('--global -g'); // alias last, space
+// etc...
+```
+
+#### desc
+
+Type: `String`
+
+The description for the Option.
+
+#### value
+
+Type: `String`
+
+The **default** value for the Option.
+
+Flags and aliases, if parsed, are `true` by default. See [`mri`](https://github.com/lukeed/mri#minimist) for more info.
+
+> **Note:** You probably only want to define a default `value` if you're expecting a `String` or `Number` value type.
+
+If you _do_ pass a `String` or `Number` value type, your flag value will be casted to the same type. See [`mri#options.default`](https://github.com/lukeed/mri#optionsdefault) for info~!
+
+
+### prog.version(str)
+
+The `--version` and `-v` flags will automatically output the Program version.
+
+#### str
+
+Type: `String`

+Default: `0.0.0`
+
+The new version number for your Program.
+
+> **Note:** Your Program `version` is `0.0.0` until you change it.
+
+### prog.parse(arr, opts)
+
+Parse a set of CLI arguments.
+
+#### arr
+
+Type: `Array`
+
+Your Program's `process.argv` input.
+
+> **Important:** Do not `.slice(2)`! Doing so will break parsing~!
+
+#### opts
+
+Type: `Object`

+Default: `{}`
+
+Additional `process.argv` parsing config. See [`mri`'s options](https://github.com/lukeed/mri#mriargs-options) for details.
+
+> **Important:** These values _override_ any internal values!
+
+```js
+prog
+  .command('hello')
+  .option('-f, --force', 'My flag');
+//=> currently has alias pair: f <--> force
+
+prog.parse(process.argv, {
+  alias: {
+    f: ['foo', 'fizz']
+  },
+  default: {
+    abc: 123
+  }
+});
+//=> ADDS alias pair: f <--> foo
+//=> REMOVES alias pair: f <--> force
+//=> ADDS alias pair: f <--> fizz
+//=> ADDS default: abc -> 123 (number)
+```
+
+#### opts.unknown
+
+Type: `Function`

+Default: `undefined`
+
+Callback to run when an unspecified option flag has been found. This is [passed directly to `mri`](https://github.com/lukeed/mri#optionsunknown).
+
+Your handler will receive the unknown flag (string) as its only argument.

+You may return a string, which will be used as a custom error message. Otherwise, a default message is displayed.
+
+```js
+sade('sirv')
+  .command('start [dir]')
+  .parse(process.argv, {
+    unknown: arg => `Custom error message: ${arg}`
+  });
+
+/*
+$ sirv start --foobar
+
+  ERROR
+    Custom error message: --foobar
+
+  Run `$ sirv --help` for more info.
+*/
+```
+
+#### opts.lazy
+
+Type: `Boolean`

+Default: `false`
+
+If true, Sade will not immediately execute the `action` handler. Instead, `parse()` will return an object of `{ name, args, handler }` shape, wherein the `name` is the command name, `args` is all arguments that _would be_ passed to the action handler, and `handler` is the function itself.
+
+From this, you may choose when to run the `handler` function. You also have the option to further modify the `args` for any reason, if needed.
+
+```js
+let { name, args, handler } = prog.parse(process.argv, { lazy:true });
+console.log('> Received command: ', name);
+
+// later on...
+handler.apply(null, args);
+```
+
+### prog.help(cmd)
+
+Manually display the help text for a given command. If no command name is provided, the general/global help is printed.
+
+Your general and command-specific help text is automatically attached to the `--help` and `-h` flags.
+
+> **Note:** You don't have to call this directly! It's automatically run when you `bin --help`
+
+#### cmd
+Type: `String`

+Default: `null`
+
+The name of the command for which to display help. Otherwise displays the general help.

+
+A simple temporary file and directory creator for [node.js.][1]
+
+[![Build Status](https://travis-ci.org/raszi/node-tmp.svg?branch=master)](https://travis-ci.org/raszi/node-tmp)
+[![Dependencies](https://david-dm.org/raszi/node-tmp.svg)](https://david-dm.org/raszi/node-tmp)
+[![npm version](https://badge.fury.io/js/tmp.svg)](https://badge.fury.io/js/tmp)
+[![API documented](https://img.shields.io/badge/API-documented-brightgreen.svg)](https://raszi.github.io/node-tmp/)

+
+## About
+
+This is a [widely used library][2] to create temporary files and directories
+in a [node.js][1] environment.
+
+Tmp offers both an asynchronous and a synchronous API. For all API calls, all
+the parameters are optional. There also exists a promisified version of the
+API, see [tmp-promise][5].
+
+Tmp uses crypto for determining random file names, or, when using templates,
+a six letter random identifier. And just in case that you do not have that much
+entropy left on your system, Tmp will fall back to pseudo random numbers.
+
+You can set whether you want to remove the temporary file on process exit or
+not.
+
+If you do not want to store your temporary directories and files in the
+standard OS temporary directory, then you are free to override that as well.
+
+## An Important Note on Compatibility
+
+See the [CHANGELOG](./CHANGELOG.md) for more information.
+
+### Version 0.1.0
+
+Since version 0.1.0, all support for node versions < 0.10.0 has been dropped.
+
+Most importantly, any support for earlier versions of node-tmp was also dropped.
+
+If you still require node versions < 0.10.0, then you must limit your node-tmp
+dependency to versions below 0.1.0.
+
+### Version 0.0.33
+
+Since version 0.0.33, all support for node versions < 0.8 has been dropped.
+
+If you still require node version 0.8, then you must limit your node-tmp
+dependency to version 0.0.33.
+
+For node versions < 0.8 you must limit your node-tmp dependency to
+versions < 0.0.33.
+
+## How to install
+
+```bash
+npm install tmp
+```
+
+## Usage
+
+Please also check [API docs][4].
+
+### Asynchronous file creation
+
+Simple temporary file creation, the file will be closed and unlinked on process exit.
+
+```javascript
+const tmp = require('tmp');
+
+tmp.file(function _tempFileCreated(err, path, fd, cleanupCallback) {
+  if (err) throw err;
+
+  console.log('File: ', path);
+  console.log('Filedescriptor: ', fd);
+  
+  // If we don't need the file anymore we could manually call the cleanupCallback
+  // But that is not necessary if we didn't pass the keep option because the library
+  // will clean after itself.
+  cleanupCallback();
+});
+```
+
+### Synchronous file creation
+
+A synchronous version of the above.
+
+```javascript
+const tmp = require('tmp');
+
+const tmpobj = tmp.fileSync();
+console.log('File: ', tmpobj.name);
+console.log('Filedescriptor: ', tmpobj.fd);
+  
+// If we don't need the file anymore we could manually call the removeCallback
+// But that is not necessary if we didn't pass the keep option because the library
+// will clean after itself.
+tmpobj.removeCallback();
+```
+
+Note that this might throw an exception if either the maximum limit of retries
+for creating a temporary name fails, or, in case that you do not have the permission
+to write to the directory where the temporary file should be created in.
+
+### Asynchronous directory creation
+
+Simple temporary directory creation, it will be removed on process exit.
+
+If the directory still contains items on process exit, then it won't be removed.
+
+```javascript
+const tmp = require('tmp');
+
+tmp.dir(function _tempDirCreated(err, path, cleanupCallback) {
+  if (err) throw err;
+
+  console.log('Dir: ', path);
+  
+  // Manual cleanup
+  cleanupCallback();
+});
+```
+
+If you want to cleanup the directory even when there are entries in it, then
+you can pass the `unsafeCleanup` option when creating it.
+
+### Synchronous directory creation
+
+A synchronous version of the above.
+
+```javascript
+const tmp = require('tmp');
+
+const tmpobj = tmp.dirSync();
+console.log('Dir: ', tmpobj.name);
+// Manual cleanup
+tmpobj.removeCallback();
+```
+
+Note that this might throw an exception if either the maximum limit of retries
+for creating a temporary name fails, or, in case that you do not have the permission
+to write to the directory where the temporary directory should be created in.
+
+### Asynchronous filename generation
+
+It is possible with this library to generate a unique filename in the specified
+directory.
+
+```javascript
+const tmp = require('tmp');
+
+tmp.tmpName(function _tempNameGenerated(err, path) {
+    if (err) throw err;
+
+    console.log('Created temporary filename: ', path);
+});
+```
+
+### Synchronous filename generation
+
+A synchronous version of the above.
+
+```javascript
+const tmp = require('tmp');
+
+const name = tmp.tmpNameSync();
+console.log('Created temporary filename: ', name);
+```
+
+## Advanced usage
+
+### Asynchronous file creation
+
+Creates a file with mode `0644`, prefix will be `prefix-` and postfix will be `.txt`.
+
+```javascript
+const tmp = require('tmp');
+
+tmp.file({ mode: 0o644, prefix: 'prefix-', postfix: '.txt' }, function _tempFileCreated(err, path, fd) {
+  if (err) throw err;
+
+  console.log('File: ', path);
+  console.log('Filedescriptor: ', fd);
+});
+```
+
+### Synchronous file creation
+
+A synchronous version of the above.
+
+```javascript
+const tmp = require('tmp');
+
+const tmpobj = tmp.fileSync({ mode: 0o644, prefix: 'prefix-', postfix: '.txt' });
+console.log('File: ', tmpobj.name);
+console.log('Filedescriptor: ', tmpobj.fd);
+```
+
+### Controlling the Descriptor
+
+As a side effect of creating a unique file `tmp` gets a file descriptor that is
+returned to the user as the `fd` parameter.  The descriptor may be used by the
+application and is closed when the `removeCallback` is invoked.
+
+In some use cases the application does not need the descriptor, needs to close it
+without removing the file, or needs to remove the file without closing the
+descriptor.  Two options control how the descriptor is managed:
+
+* `discardDescriptor` - if `true` causes `tmp` to close the descriptor after the file
+  is created.  In this case the `fd` parameter is undefined.
+* `detachDescriptor` - if `true` causes `tmp` to return the descriptor in the `fd`
+  parameter, but it is the application's responsibility to close it when it is no
+  longer needed.
+
+```javascript
+const tmp = require('tmp');
+
+tmp.file({ discardDescriptor: true }, function _tempFileCreated(err, path, fd, cleanupCallback) {
+  if (err) throw err;
+  // fd will be undefined, allowing application to use fs.createReadStream(path)
+  // without holding an unused descriptor open.
+});
+```
+
+```javascript
+const tmp = require('tmp');
+
+tmp.file({ detachDescriptor: true }, function _tempFileCreated(err, path, fd, cleanupCallback) {
+  if (err) throw err;
+
+  cleanupCallback();
+  // Application can store data through fd here; the space used will automatically
+  // be reclaimed by the operating system when the descriptor is closed or program
+  // terminates.
+});
+```
+
+### Asynchronous directory creation
+
+Creates a directory with mode `0755`, prefix will be `myTmpDir_`.
+
+```javascript
+const tmp = require('tmp');
+
+tmp.dir({ mode: 0o750, prefix: 'myTmpDir_' }, function _tempDirCreated(err, path) {
+  if (err) throw err;
+
+  console.log('Dir: ', path);
+});
+```
+
+### Synchronous directory creation
+
+Again, a synchronous version of the above.
+
+```javascript
+const tmp = require('tmp');
+
+const tmpobj = tmp.dirSync({ mode: 0750, prefix: 'myTmpDir_' });
+console.log('Dir: ', tmpobj.name);
+```
+
+### mkstemp like, asynchronously
+
+Creates a new temporary directory with mode `0700` and filename like `/tmp/tmp-nk2J1u`.
+
+IMPORTANT NOTE: template no longer accepts a path. Use the dir option instead if you
+require tmp to create your temporary filesystem object in a different place than the
+default `tmp.tmpdir`.
+
+```javascript
+const tmp = require('tmp');
+
+tmp.dir({ template: 'tmp-XXXXXX' }, function _tempDirCreated(err, path) {
+  if (err) throw err;
+
+  console.log('Dir: ', path);
+});
+```
+
+### mkstemp like, synchronously
+
+This will behave similarly to the asynchronous version.
+
+```javascript
+const tmp = require('tmp');
+
+const tmpobj = tmp.dirSync({ template: 'tmp-XXXXXX' });
+console.log('Dir: ', tmpobj.name);
+```
+
+### Asynchronous filename generation
+
+Using `tmpName()` you can create temporary file names asynchronously.
+The function accepts all standard options, e.g. `prefix`, `postfix`, `dir`, and so on.
+
+You can also leave out the options altogether and just call the function with a callback as first parameter.
+
+```javascript
+const tmp = require('tmp');
+
+const options = {};
+
+tmp.tmpName(options, function _tempNameGenerated(err, path) {
+    if (err) throw err;
+
+    console.log('Created temporary filename: ', path);
+});
+```
+
+### Synchronous filename generation
+
+The `tmpNameSync()` function works similarly to `tmpName()`.
+Again, you can leave out the options altogether and just invoke the function without any parameters.
+
+```javascript
+const tmp = require('tmp');
+const options = {};
+const tmpname = tmp.tmpNameSync(options);
+console.log('Created temporary filename: ', tmpname);
+```
+
+## Graceful cleanup
+
+If graceful cleanup is set, tmp will remove all controlled temporary objects on process exit, otherwise the
+temporary objects will remain in place, waiting to be cleaned up on system restart or otherwise scheduled temporary
+object removal.
+
+To enforce this, you can call the `setGracefulCleanup()` method:
+
+```javascript
+const tmp = require('tmp');
+
+tmp.setGracefulCleanup();
+```
+
+## Options
+
+All options are optional :)
+
+  * `name`: a fixed name that overrides random name generation, the name must be relative and must not contain path segments
+  * `mode`: the file mode to create with, falls back to `0o600` on file creation and `0o700` on directory creation
+  * `prefix`: the optional prefix, defaults to `tmp`
+  * `postfix`: the optional postfix
+  * `template`: [`mkstemp`][3] like filename template, no default, can be either an absolute or a relative path that resolves 
+     to a relative path of the system's default temporary directory, must include `XXXXXX` once for random name generation, e.g.
+     'foo/bar/XXXXXX'. Absolute paths are also fine as long as they are relative to os.tmpdir().
+     Any directories along the so specified path must exist, otherwise a ENOENT error will be thrown upon access, 
+     as tmp will not check the availability of the path, nor will it establish the requested path for you. 
+  * `dir`: the optional temporary directory that must be relative to the system's default temporary directory.
+     absolute paths are fine as long as they point to a location under the system's default temporary directory.
+     Any directories along the so specified path must exist, otherwise a ENOENT error will be thrown upon access, 
+     as tmp will not check the availability of the path, nor will it establish the requested path for you.
+  * `tmpdir`: allows you to override the system's root tmp directory
+  * `tries`: how many times should the function try to get a unique filename before giving up, default `3`
+  * `keep`: signals that the temporary file or directory should not be deleted on exit, default is `false`
+    * In order to clean up, you will have to call the provided `cleanupCallback` function manually.
+  * `unsafeCleanup`: recursively removes the created temporary directory, even when it's not empty. default is `false`
+  * `detachDescriptor`: detaches the file descriptor, caller is responsible for closing the file, tmp will no longer try closing the file during garbage collection
+  * `discardDescriptor`: discards the file descriptor (closes file, fd is -1), tmp will no longer try closing the file during garbage collection

+
+## What is this?
+
+`trough` is like [`ware`][ware] with less sugar.
+Middleware functions can also change the input of the next.
+
+The word **trough** (`/trôf/`) means a channel used to convey a liquid.
+
+## When should I use this?
+
+You can use this package when you’re building something that accepts “plugins”,
+which are functions, that can be sync or async, promises or callbacks.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 12.20+, 14.14+, or 16.0+), install with [npm][]:
+
+```sh
+npm install trough
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {trough} from "https://esm.sh/trough@2"
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import process from 'node:process'
+import fs from 'node:fs'
+import path from 'node:path'
+import {trough} from 'trough'
+
+const pipeline = trough()
+  .use(function (fileName) {
+    console.log('Checking… ' + fileName)
+  })
+  .use(function (fileName) {
+    return path.join(process.cwd(), fileName)
+  })
+  .use(function (filePath, next) {
+    fs.stat(filePath, function (error, stats) {
+      next(error, {filePath, stats})
+    })
+  })
+  .use(function (ctx, next) {
+    if (ctx.stats.isFile()) {
+      fs.readFile(ctx.filePath, next)
+    } else {
+      next(new Error('Expected file'))
+    }
+  })
+
+pipeline.run('readme.md', console.log)
+pipeline.run('node_modules', console.log)
+```
+
+Yields:
+
+```txt
+Checking… readme.md
+Checking… node_modules
+Error: Expected file
+    at ~/example.js:22:12
+    at wrapped (~/node_modules/trough/index.js:111:16)

+    at ~/example.js:15:7
+    at FSReqCallback.oncomplete (node:fs:199:5)
+null 
+```
+
+## API
+
+This package exports the identifiers `trough` and `wrap`.
+There is no default export.
+
+### `trough()`
+
+Create a new [`Trough`][trough].
+
+### `wrap(middleware, callback)(…input)`
+
+Call `middleware` with all input.
+If `middleware` accepts more arguments than given in input, an extra `done`
+function is passed in after the input when calling it.
+In that case, `done` must be called.
+
+The first value in `input` is the main input value.
+All other input values are the rest input values.
+The values given to `callback` are the input values, merged with every
+non-nullish output value.
+
+*   If `middleware` throws an error, returns a promise that is rejected, or
+    calls the given `done` function with an error, `callback` is called with
+    that error
+*   If `middleware` returns a value or returns a promise that is resolved, that
+    value is the main output value
+*   If `middleware` calls `done`, all non-nullish values except for the first
+    one (the error) overwrite the output values
+
+### `Trough`
+
+A pipeline.
+
+#### `Trough#run([input…, ]done)`
+
+Run the pipeline (all [`use()`][use]d middleware).
+Calls [`done`][done] on completion with either an error or the output of the
+last middleware.
+
+> 👉 **Note**: as the length of input defines whether [async][] functions get a
+> `next` function, it’s recommended to keep `input` at one value normally.
+
+##### `function done(err?, [output…])`
+
+The final handler passed to [`run()`][run], called with an error if a
+[middleware function][fn] rejected, passed, or threw one, or the output of the
+last middleware function.
+
+#### `Trough#use(fn)`
+
+Add `fn`, a [middleware function][fn], to the pipeline.
+
+##### `function fn([input…, ][next])`
+
+A middleware function called with the output of its predecessor.
+
+###### Synchronous
+
+If `fn` returns or throws an error, the pipeline fails and `done` is called
+with that error.
+
+If `fn` returns a value (neither `null` nor `undefined`), the first `input` of
+the next function is set to that value (all other `input` is passed through).
+
+The following example shows how returning an error stops the pipeline:
+
+```js
+import {trough} from 'trough'
+
+trough()
+  .use(function (thing) {
+    return new Error('Got: ' + thing)
+  })
+  .run('some value', console.log)
+```
+
+Yields:
+
+```txt
+Error: Got: some value
+    at ~/example.js:5:12
+    …
+```
+
+The following example shows how throwing an error stops the pipeline:
+
+```js
+import {trough} from 'trough'
+
+trough()
+  .use(function (thing) {
+    throw new Error('Got: ' + thing)
+  })
+  .run('more value', console.log)
+```
+
+Yields:
+
+```txt
+Error: Got: more value
+    at ~/example.js:5:11
+    …
+```
+
+The following example shows how the first output can be modified:
+
+```js
+import {trough} from 'trough'
+
+trough()
+  .use(function (thing) {
+    return 'even ' + thing
+  })
+  .run('more value', 'untouched', console.log)
+```
+
+Yields:
+
+```txt
+null 'even more value' 'untouched'
+```
+
+###### Promise
+
+If `fn` returns a promise, and that promise rejects, the pipeline fails and
+`done` is called with the rejected value.
+
+If `fn` returns a promise, and that promise resolves with a value (neither
+`null` nor `undefined`), the first `input` of the next function is set to that
+value (all other `input` is passed through).
+
+The following example shows how rejecting a promise stops the pipeline:
+
+```js
+import {trough} from 'trough'
+

+  .use(function (thing) {
+    return new Promise(function (resolve, reject) {
+      reject('Got: ' + thing)
+    })
+  })
+  .run('thing', console.log)
+```
+
+Yields:
+
+```txt
+Got: thing
+```
+
+The following example shows how the input isn’t touched by resolving to `null`.
+
+```js
+import {trough} from 'trough'
+
+trough()
+  .use(function () {
+    return new Promise(function (resolve) {
+      setTimeout(function () {
+        resolve(null)
+      }, 100)
+    })
+  })
+  .run('Input', console.log)
+```
+
+Yields:
+
+```txt
+null 'Input'
+```
+
+###### Asynchronous
+
+If `fn` accepts one more argument than the given `input`, a `next` function is
+given (after the input).  `next` must be called, but doesn’t have to be called
+async.
+
+If `next` is given a value (neither `null` nor `undefined`) as its first
+argument, the pipeline fails and `done` is called with that value.
+
+If `next` is given no value (either `null` or `undefined`) as the first
+argument, all following non-nullish values change the input of the following
+function, and all nullish values default to the `input`.
+
+The following example shows how passing a first argument stops the pipeline:
+
+```js
+import {trough} from 'trough'
+
+trough()
+  .use(function (thing, next) {
+    next(new Error('Got: ' + thing))
+  })
+  .run('thing', console.log)
+```
+
+Yields:
+
+```txt
+Error: Got: thing
+    at ~/example.js:5:10
+```
+
+The following example shows how more values than the input are passed.
+
+```js
+import {trough} from 'trough'
+
+trough()
+  .use(function (thing, next) {
+    setTimeout(function () {
+      next(null, null, 'values')
+    }, 100)
+  })
+  .run('some', console.log)
+```
+
+Yields:
+
+```txt
+null 'some' 'values'
+```

+// parameters in JSDoc-based TypeScript, which is a feature we use to type that:
+//
+// ```js
+// .use(somePlugin, theOptions)
+// ```
+//
+// `theOptions` matches the options that `somePlugin` expects and thus is very
+// important for making unified usable in TypeScript.

+**unified** is an interface for processing text using syntax trees.
+It’s what powers [**remark**][remark] (Markdown), [**retext**][retext] (natural
+language), and [**rehype**][rehype] (HTML), and allows for processing between
+formats.
+
+## Intro
+
+**unified** enables new exciting projects like [Gatsby][] to pull in Markdown,
+[MDX][] to embed [JSX][], and [Prettier][] to format it.
+It’s used in about 700k projects on GitHub and has about 35m downloads each
+month on npm: you’re probably using it.
+Some notable users are [Node.js][], [Vercel][], [Netlify][], [GitHub][],
+[Mozilla][], [WordPress][], [Adobe][], [Facebook][], [Google][], and many more.

+## Description
+
+**unified** is an interface for processing text using syntax trees.
+Syntax trees are a representation of text understandable to programs.
+Those programs, called [*plugin*][plugin]s, take these trees and inspect and
+modify them.
+To get to the syntax tree from text, there is a [*parser*][parser].
+To get from that back to text, there is a [*compiler*][compiler].
+This is the [*process*][process] of a *processor*.
+
+```ascii
+| ........................ process ........................... |
+| .......... parse ... | ... run ... | ... stringify ..........|
+
+          +--------+                     +----------+
+Input ->- | Parser | ->- Syntax Tree ->- | Compiler | ->- Output
+          +--------+          |          +----------+
+                              X
+                              |
+                       +--------------+
+                       | Transformers |
+                       +--------------+
+```
+
+###### Processors
+
+Every **processor** implements another processor.
+To create a processor, call another processor.
+The new processor is configured to work the same as its ancestor.
+But when the descendant processor is configured in the future it does not affect
+the ancestral processor.
+
+When processors are exposed from a module (for example, `unified` itself) they
+should not be configured directly, as that would change their behavior for all
+module users.
+Those processors are [*frozen*][freeze] and they should be called to create a
+new processor before they are used.
+
+###### Syntax trees
+
+The **syntax trees** used in **unified** are [**unist**][unist] nodes.
+A [**node**][node] is a plain JavaScript objects with a `type` field.
+The semantics of nodes and format of syntax trees is defined by other projects.
+
+There are several [*utilities*][unist-utilities] for working with nodes.
+
+*   [**esast**][esast] — JS
+*   [**hast**][hast] — HTML
+*   [**mdast**][mdast] — Markdown
+*   [**nlcst**][nlcst] — Natural language
+*   [**xast**][xast] — XML
+
+###### List of processors
+
+The following projects process different [*syntax tree*][syntax-tree] formats.
+They parse text to a syntax tree and compile that back to text.
+These processors can be used as is, or their parser and compiler can be mixed
+and matched with **unified** and plugins to process between different syntaxes.
+
+*   [**rehype**][rehype] ([*hast*][hast]) — HTML
+*   [**remark**][remark] ([*mdast*][mdast]) — Markdown
+*   [**retext**][retext] ([*nlcst*][nlcst]) — Natural language
+
+###### List of plugins
+
+The below [**plugins**][plugin] work with **unified**, on all [*syntax
+tree*][syntax-tree] formats:
+
+*   [`unified-diff`](https://github.com/unifiedjs/unified-diff)
+    — Ignore messages for unchanged lines in Travis
+*   [`unified-message-control`](https://github.com/unifiedjs/unified-message-control)
+    — Enable, disable, and ignore messages
+
+See [**remark**][remark-plugins], [**rehype**][rehype-plugins], and
+[**retext**][retext-plugins] for their lists of plugins.
+
+###### File
+
+When processing a document, **metadata** is often gathered about that document.
+[**vfile**][vfile] is a virtual file format that stores data, metadata, and
+messages about files for **unified** and its plugins.
+
+There are several [*utilities*][vfile-utilities] for working with these files.
+
+###### Configuration
+
+[*Processors*][processors] are configured with [*plugin*][plugin]s or
+with the [`data`][data] method.
+
+###### Integrations
+
+**unified** can integrate with the file system with [`unified-engine`][engine].
+CLI apps can be created with [`unified-args`][args], Gulp plugins with
+[`unified-engine-gulp`][gulp], and Atom Linters with
+[`unified-engine-atom`][atom].
+
+[`unified-stream`][stream] provides a streaming interface.
+
+###### Programming interface
+
+The API provided by **unified** allows multiple files to be processed and gives
+access to *metadata* (such as lint messages):
+
+```js
+import {unified} from 'unified'
+import remarkParse from 'remark-parse'
+import remarkPresetLintMarkdownStyleGuide from 'remark-preset-lint-markdown-style-guide'
+import remarkRetext from 'remark-retext'
+import retextEnglish from 'retext-english'
+import retextEquality from 'retext-equality'
+import remarkRehype from 'remark-rehype'
+import rehypeStringify from 'rehype-stringify'
+import {reporter} from 'vfile-reporter'
+
+unified()
+  .use(remarkParse)
+  .use(remarkPresetLintMarkdownStyleGuide)
+  .use(remarkRetext, unified().use(retextEnglish).use(retextEquality))
+  .use(remarkRehype)
+  .use(rehypeStringify)
+  .process('*Emphasis* and _stress_, you guys!')
+  .then(
+    (file) => {
+      console.error(reporter(file))
+      console.log(String(file))
+    },
+    (error) => {
+      // Handle your error here!
+      throw error
+    }
+  )
+```
+
+Yields:
+
+```txt
+  1:16-1:24  warning  Emphasis should use `*` as a marker                                  emphasis-marker  remark-lint
+  1:30-1:34  warning  `guys` may be insensitive, use `people`, `persons`, `folks` instead  gals-man         retext-equality
+
+⚠ 2 warnings
+```
+
+```html
+
Emphasis and stress, you guys!

+```
+
+###### Processing between syntaxes
+
+[*Processors*][processors] can be combined in two modes.
+
+**Bridge** mode transforms the [*syntax tree*][syntax-tree] from one format
+(*origin*) to another (*destination*).
+Another processor runs on the destination tree.
+Finally, the original processor continues transforming the origin tree.
+
+**Mutate** mode also transforms the syntax tree from one format to another.
+But the original processor continues transforming the destination tree.
+
+In the previous example (“Programming interface”), `remark-retext` is used in
+*bridge* mode: the origin syntax tree is kept after [**retext**][retext] is
+done; whereas `remark-rehype` is used in *mutate* mode: it sets a new syntax
+tree and discards the origin tree.
+
+*   [`remark-retext`][remark-retext]
+*   [`remark-rehype`][remark-rehype]
+*   [`rehype-retext`][rehype-retext]
+*   [`rehype-remark`][rehype-remark]
+
+## API
+
+This package exports the following identifiers: `unified`.
+There is no default export.
+
+### `processor()`
+
+[*Processor*][processors] describing how to *process* text.
+
+###### Returns
+
+`Function` — New [*unfrozen*][freeze] processor that is configured to work the
+same as its ancestor.
+When the descendant processor is configured in the future it does not affect the
+ancestral processor.
+
+###### Example
+
+The following example shows how a new processor can be created (from the remark
+processor) and linked to **stdin**(4) and **stdout**(4).
+
+```js
+import {remark} from 'remark'
+import concatStream from 'concat-stream'
+
+process.stdin.pipe(
+  concatStream((buf) => {
+    process.stdout.write(remark().processSync(buf).toString())
+  })
+)
+```
+
+### `processor.use(plugin[, options])`
+
+[*Configure*][configuration] the processor to use a [*plugin*][plugin] and
+optionally configure that plugin with options.
+
+If the processor is already using this plugin, the previous plugin configuration
+is changed based on the options that are passed in.
+The plugin is not added a second time.
+
+###### Signatures
+
+*   `processor.use(plugin[, options])`
+*   `processor.use(preset)`
+*   `processor.use(list)`
+
+###### Parameters
+
+*   `plugin` ([`Attacher`][plugin])
+*   `options` (`*`, optional) — Configuration for `plugin`
+*   `preset` (`Object`) — Object with an optional `plugins` (set to `list`),
+    and/or an optional `settings` object
+*   `list` (`Array`) — List of plugins, presets, and pairs (`plugin` and
+    `options` in an array)
+
+###### Returns
+
+`processor` — The processor that `use` was called on.
+
+###### Note
+
+`use` cannot be called on [*frozen*][freeze] processors.
+Call the processor first to create a new unfrozen processor.
+
+###### Example
+
+There are many ways to pass plugins to `.use()`.
+The below example gives an overview.
+
+```js
+import {unified} from 'unified'
+
+unified()
+  // Plugin with options:
+  .use(pluginA, {x: true, y: true})
+  // Passing the same plugin again merges configuration (to `{x: true, y: false, z: true}`):
+  .use(pluginA, {y: false, z: true})
+  // Plugins:
+  .use([pluginB, pluginC])
+  // Two plugins, the second with options:
+  .use([pluginD, [pluginE, {}]])
+  // Preset with plugins and settings:
+  .use({plugins: [pluginF, [pluginG, {}]], settings: {position: false}})
+  // Settings only:
+  .use({settings: {position: false}})
+```
+
+### `processor.parse(file)`
+
+Parse text to a [*syntax tree*][syntax-tree].
+
+###### Parameters
+
+*   `file` ([`VFile`][vfile]) — [*File*][file], any value accepted by `vfile()`
+
+###### Returns
+
+[`Node`][node] — Parsed [*syntax tree*][syntax-tree] representing `file`.
+
+###### Note
+
+`parse` freezes the processor if not already [*frozen*][freeze].
+
+`parse` performs the [*parse phase*][description], not the *run phase* or other
+phases.
+
+###### Example
+
+The below example shows how `parse` can be used to create a syntax tree from a
+file.
+
+```js
+import {unified} from 'unified'
+import remarkParse from 'remark-parse'
+
+const tree = unified().use(remarkParse).parse('# Hello world!')
+
+console.log(tree)
+```
+
+Yields:
+
+```js
+{
+  type: 'root',
+  children: [
+    {type: 'heading', depth: 1, children: [Array], position: [Position]}
+  ],
+  position: {
+    start: {line: 1, column: 1, offset: 0},
+    end: {line: 1, column: 15, offset: 14}
+  }
+}
+```
+
+#### `processor.Parser`
+
+A **parser** handles the parsing of text to a [*syntax tree*][syntax-tree].
+Used in the [*parse phase*][description] and called with a `string` and
+[`VFile`][vfile] representation of the text to parse.
+
+`Parser` can be a function, in which case it must return a [`Node`][node]: the
+syntax tree representation of the given file.
+
+`Parser` can also be a constructor function (a function with a `parse` field, or
+other fields, in its `prototype`), in which case it’s constructed with `new`.
+Instances must have a `parse` method that is called without arguments and must
+return a [`Node`][node].
+
+### `processor.stringify(node[, file])`
+
+Compile a [*syntax tree*][syntax-tree].
+
+###### Parameters
+
+*   `node` ([`Node`][node]) — [*Syntax tree*][syntax-tree] to compile
+*   `file` ([`VFile`][vfile], optional) — [*File*][file], any value accepted by
+    `vfile()`
+
+###### Returns
+
+`string` or `Buffer` (see notes) — Textual representation of the [*syntax
+tree*][syntax-tree]
+
+###### Note
+
+`stringify` freezes the processor if not already [*frozen*][freeze].
+
+`stringify` performs the [*stringify phase*][description], not the *run phase*
+or other phases.
+
+unified typically compiles by serializing: most [*compiler*][compiler]s return
+`string` (or `Buffer`).
+Some compilers, such as the one configured with [`rehype-react`][rehype-react],
+return other values (in this case, a React tree).
+If you’re using a compiler doesn’t serialize, expect different result values.
+When using TypeScript, cast the type on your side.
+
+###### Example
+
+The below example shows how `stringify` can be used to serialize a syntax tree.
+
+```js
+import {unified} from 'unified'
+import rehypeStringify from 'rehype-stringify'
+import {h} from 'hastscript'
+
+const tree = h('h1', 'Hello world!')
+
+const doc = unified().use(rehypeStringify).stringify(tree)
+
+console.log(doc)
+```
+
+Yields:
+
+```html
+
Hello world!

+```
+
+#### `processor.Compiler`
+
+A **compiler** handles the compiling of a [*syntax tree*][syntax-tree] to text.
+Used in the [*stringify phase*][description] and called with a [`Node`][node]
+and [`VFile`][file] representation of syntax tree to compile.
+
+`Compiler` can be a function, in which case it should return a `string`: the
+textual representation of the syntax tree.
+
+`Compiler` can also be a constructor function (a function with a `compile`
+field, or other fields, in its `prototype`), in which case it’s constructed with
+`new`.
+Instances must have a `compile` method that is called without arguments and
+should return a `string`.
+
+### `processor.run(node[, file][, done])`
+
+Run [*transformers*][transformer] on a [*syntax tree*][syntax-tree].
+
+###### Parameters
+
+*   `node` ([`Node`][node]) — [*Syntax tree*][syntax-tree] to run on
+*   `file` ([`VFile`][vfile], optional) — [*File*][file], any value accepted by
+    `vfile()`
+*   `done` ([`Function`][run-done], optional) — Callback
+
+###### Returns
+
+[`Promise`][promise] if `done` is not given.
+The returned promise is rejected with a fatal error, or resolved with the
+transformed [*syntax tree*][syntax-tree].
+
+###### Note
+
+`run` freezes the processor if not already [*frozen*][freeze].
+
+`run` performs the [*run phase*][description], not other phases.
+
+#### `function done(err[, node, file])`
+
+Callback called when [*transformers*][transformer] are done.
+Called with either an error or results.
+
+###### Parameters
+
+*   `err` (`Error`, optional) — Fatal error
+*   `node` ([`Node`][node], optional) — Transformed [*syntax tree*][syntax-tree]
+*   `file` ([`VFile`][vfile], optional) — [*File*][file]
+
+###### Example
+
+The below example shows how `run` can be used to transform a syntax tree.
+
+```js
+import {unified} from 'unified'
+import remarkReferenceLinks from 'remark-reference-links'
+import {u} from 'unist-builder'
+
+const tree = u('root', [
+  u('paragraph', [
+    u('link', {href: 'https://example.com'}, [u('text', 'Example Domain')])
+  ])
+])
+
+unified()

+    (changedTree) => console.log(changedTree),
+    (error) => {
+      // Handle your error here!
+      throw error
+    }
+  )
+```
+
+Yields:
+
+```js
+{
+  type: 'root',
+  children: [
+    {type: 'paragraph', children: [Array]},
+    {type: 'definition', identifier: '1', title: undefined, url: undefined}
+  ]
+}
+```
+
+### `processor.runSync(node[, file])`
+
+Run [*transformers*][transformer] on a [*syntax tree*][syntax-tree].
+
+An error is thrown if asynchronous [*plugin*][plugin]s are configured.
+
+###### Parameters
+
+*   `node` ([`Node`][node]) — [*Syntax tree*][syntax-tree] to run on
+*   `file` ([`VFile`][vfile], optional) — [*File*][file], any value accepted by
+    `vfile()`
+
+###### Returns
+
+[`Node`][node] — Transformed [*syntax tree*][syntax-tree].
+
+###### Note
+
+`runSync` freezes the processor if not already [*frozen*][freeze].
+
+`runSync` performs the [*run phase*][description], not other phases.
+
+### `processor.process(file[, done])`
+
+[*Process*][description] the given [*file*][file] as configured on the
+processor.
+
+###### Parameters
+
+*   `file` ([`VFile`][vfile]) — [*File*][file], any value accepted by `vfile()`
+*   `done` ([`Function`][process-done], optional) — Callback
+
+###### Returns
+
+[`Promise`][promise] if `done` is not given.
+The returned promise is rejected with a fatal error, or resolved with the
+processed [*file*][file].
+
+The parsed, transformed, and compiled value is exposed on
+[`file.value`][vfile-value] or `file.result` (see notes).
+
+###### Note
+
+`process` freezes the processor if not already [*frozen*][freeze].
+
+`process` performs the [*parse*, *run*, and *stringify* phases][description].
+
+unified typically compiles by serializing: most [*compiler*][compiler]s return
+`string` (or `Buffer`).
+Some compilers, such as the one configured with [`rehype-react`][rehype-react],
+return other values (in this case, a React tree).
+If you’re using a compiler that serializes, the result is available at
+`file.value`.
+Otherwise, the result is available at `file.result`.
+
+###### Example
+
+The below example shows how `process` can be used to process a file, whether
+transformers are asynchronous or not, with promises.
+
+```js
+import {unified} from 'unified'
+import remarkParse from 'remark-parse'

+
+### `processor.data([key[, value]])`
+
+[*Configure*][configuration] the processor with information available to all
+[*plugin*][plugin]s.
+Information is stored in an in-memory key-value store.
+
+Typically, options can be given to a specific plugin, but sometimes it makes
+sense to have information shared with several plugins.
+For example, a list of HTML elements that are self-closing, which is needed
+during all [*phases*][description] of the *process*.
+
+###### Signatures
+
+*   `processor = processor.data(key, value)`
+*   `processor = processor.data(values)`
+*   `value = processor.data(key)`
+*   `info = processor.data()`
+
+###### Parameters
+
+*   `key` (`string`, optional) — Identifier
+*   `value` (`*`, optional) — Value to set
+*   `values` (`Object`, optional) — Values to set
+
+###### Returns
+
+*   `processor` — If setting, the processor that `data` is called on
+*   `value` (`*`) — If getting, the value at `key`
+*   `info` (`Object`) — Without arguments, the key-value store
+
+###### Note
+
+Setting information cannot occur on [*frozen*][freeze] processors.
+Call the processor first to create a new unfrozen processor.
+
+###### Example
+
+The following example show how to get and set information:
+
+```js
+import {unified} from 'unified'
+
+const processor = unified().data('alpha', 'bravo')
+
+processor.data('alpha') // => 'bravo'
+
+processor.data() // => {alpha: 'bravo'}
+
+processor.data({charlie: 'delta'})
+
+processor.data() // => {charlie: 'delta'}
+```
+
+### `processor.freeze()`
+
+**Freeze** a processor.
+*Frozen* processors are meant to be extended and not to be configured directly.
+
+Once a processor is frozen it cannot be *unfrozen*.
+New processors working the same way can be created by calling the processor.
+
+It’s possible to freeze processors explicitly by calling `.freeze()`.
+Processors freeze implicitly when [`.parse()`][parse], [`.run()`][run],
+[`.runSync()`][run-sync], [`.stringify()`][stringify], [`.process()`][process],
+or [`.processSync()`][process-sync] are called.
+
+###### Returns
+
+`processor` — The processor that `freeze` was called on.
+
+###### Example
+
+The following example, `index.js`, shows how rehype prevents extensions to
+itself:
+
+```js
+import {unified} from 'unified'
+import remarkParse from 'rehype-parse'
+import remarkStringify from 'rehype-stringify'
+
+export const rehype = unified().use(remarkParse).use(remarkStringify).freeze()
+```
+
+The below example, `a.js`, shows how that processor can be used and configured.
+
+```js
+import {rehype} from 'rehype'
+import rehypeFormat from 'rehype-format'
+// …
+
+rehype()
+  .use(rehypeFormat)
+  // …
+```
+
+The below example, `b.js`, shows a similar looking example that operates on the
+frozen rehype interface because it does not call `rehype`.
+If this behavior was allowed it would result in unexpected behavior so an
+error is thrown.
+**This is invalid**:
+
+```js
+import {rehype} from 'rehype'
+import rehypeFormat from 'rehype-format'
+// …
+
+rehype
+  .use(rehypeFormat)
+  // …
+```

+## `Plugin`
+
+**Plugins** [*configure*][configuration] the processors they are applied on in

+
+### `function attacher([options])`
+
+**Attachers** are materialized [*plugin*][plugin]s.
+An attacher is a function that can receive options and
+[*configures*][configuration] the processor.
+
+Attachers change the processor, such as the [*parser*][parser], the
+[*compiler*][compiler], configuring [*data*][data], or by specifying how the
+[*syntax tree*][syntax-tree] or [*file*][file] are handled.
+
+###### Context
+
+The context object (`this`) is set to the processor the attacher is applied on.
+
+###### Parameters
+
+*   `options` (`*`, optional) — Configuration
+
+###### Returns
+
+[`transformer`][transformer] — Optional.
+
+###### Note
+
+Attachers are called when the processor is [*frozen*][freeze], not when they are
+applied.
+
+### `function transformer(node, file[, next])`
+
+**Transformers** handle [*syntax tree*][syntax-tree]s and [*file*][file]s.
+A transformer is a function that is called each time a syntax tree and file are
+passed through the [*run phase*][description].
+If an error occurs (either because it’s thrown, returned, rejected, or passed to
+[`next`][next]), the process stops.
+
+The *run phase* is handled by [`trough`][trough], see its documentation for the
+exact semantics of these functions.
+
+###### Parameters
+
+*   `node` ([`Node`][node]) — [*Syntax tree*][syntax-tree] to handle
+*   `file` ([`VFile`][vfile]) — [*File*][file] to handle
+*   `next` ([`Function`][next], optional)
+
+###### Returns
+
+*   `void` — If nothing is returned, the next transformer keeps using same tree.
+*   `Error` — Fatal error to stop the process
+*   `node` ([`Node`][node]) — New [*syntax tree*][syntax-tree].
+    If returned, the next transformer is given this new tree
+*   `Promise` — Returned to perform an asynchronous operation.
+    The promise **must** be resolved (optionally with a [`Node`][node]) or
+    rejected (optionally with an `Error`)
+
+#### `function next(err[, tree[, file]])`
+
+If the signature of a [*transformer*][transformer] includes `next` (the third
+argument), the transformer **may** perform asynchronous operations, and **must**
+call `next()`.
+
+###### Parameters
+
+*   `err` (`Error`, optional) — Fatal error to stop the process
+*   `node` ([`Node`][node], optional) — New [*syntax tree*][syntax-tree].
+    If given, the next transformer is given this new tree
+*   `file` ([`VFile`][vfile], optional) — New [*file*][file].
+    If given, the next transformer is given this new file
+
+## `Preset`
+
+**Presets** are sharable [*configuration*][configuration].
+They can contain [*plugins*][plugin] and settings.
+
+###### Example
+
+`preset.js`:
+
+```js
+import remarkPresetLintRecommended from 'remark-preset-lint-recommended'
+import remarkPresetLintConsistent from 'remark-preset-lint-consistent'
+import remarkCommentConfig from 'remark-comment-config'
+import remarkToc from 'remark-toc'

+The project was authored by [**@wooorm**](https://github.com/wooorm).
+
+Although `unified` since moved its plugin architecture to [`trough`][trough],
+thanks to [**@calvinfo**](https://github.com/calvinfo),
+[**@ianstormtaylor**](https://github.com/ianstormtaylor), and others for their
+work on [`ware`][ware], as it was a huge initial inspiration.

+## What is this?
+
+This package is a small utility that checks that a node is a certain node.
+
+## When should I use this?
+
+Use this small utility if you find yourself repeating code for checking what
+nodes are.
+
+A similar package, [`hast-util-is-element`][hast-util-is-element], works on hast
+elements.
+
+For more advanced tests, [`unist-util-select`][unist-util-select] can be used
+to match against CSS selectors.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 14.14+ and 16.0+), install with [npm][]:
+
+```sh
+npm install unist-util-is
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {is} from 'https://esm.sh/unist-util-is@5'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import {is} from 'unist-util-is'
+
+const node = {type: 'strong'}
+const parent = {type: 'paragraph', children: [node]}
+
+is() // => false
+is({children: []}) // => false
+is(node) // => true
+is(node, 'strong') // => true
+is(node, 'emphasis') // => false
+
+is(node, node) // => true
+is(parent, {type: 'paragraph'}) // => true
+is(parent, {type: 'strong'}) // => false
+
+is(node, test) // => false
+is(node, test, 4, parent) // => false
+is(node, test, 5, parent) // => true
+
+function test(node, n) {
+  return n === 5
+}
+```
+
+## API
+
+This package exports the identifiers [`convert`][convert] and [`is`][is].
+There is no default export.
+
+### `is(node[, test[, index, parent[, context]]])`
+
+Check if `node` is a `Node` and whether it passes the given test.
+
+###### Parameters
+
+*   `node` (`unknown`)
+    — thing to check, typically [`Node`][node]
+*   `test` ([`Test`][test] or [`PredicateTest`][predicatetest], optional)
+    — a check for a specific element
+*   `index` (`number`, optional)
+    — the node’s position in its parent
+*   `parent` ([`Node`][node], optional)
+    — the node’s parent
+*   `context` (`any`, optional)
+    — context object (`this`) to call `test` with
+
+###### Returns
+
+Whether `node` is a [`Node`][node] and passes a test (`boolean`).
+
+###### Throws
+
+When an incorrect `test`, `index`, or `parent` is given.
+There is no error thrown when `node` is not a node.
+
+### `convert(test)`
+
+Generate a check from a test.
+
+Useful if you’re going to test many nodes, for example when creating a
+utility where something else passes a compatible test.
+
+The created function is a bit faster because it expects valid input only:
+a `node`, `index`, and `parent`.
+
+###### Parameters
+
+*   `test` ([`Test`][test] or [`PredicateTest`][predicatetest], optional)
+    — a check for a specific node
+
+###### Returns
+
+An assertion ([`AssertAnything`][assertanything] or
+[`AssertPredicate`][assertpredicate]).
+
+### `AssertAnything`
+
+Check that an arbitrary value is a node, unaware of TypeScript inferral
+(TypeScript type).
+
+###### Parameters
+
+*   `node` (`unknown`)
+    — anything (typically a node)
+*   `index` (`number`, optional)
+    — the node’s position in its parent
+*   `parent` ([`Node`][node], optional)
+    — the node’s parent
+
+###### Returns
+
+Whether this is a node and passes a test (`boolean`).
+
+### `AssertPredicate`
+
+Check that an arbitrary value is a specific node, aware of TypeScript
+(TypeScript type).
+
+###### Type parameters
+
+*   `Kind` ([`Node`][node])
+    — node type
+
+###### Parameters
+
+*   `node` (`unknown`)
+    — anything (typically a node)
+*   `index` (`number`, optional)
+    — the node’s position in its parent
+*   `parent` ([`Node`][node], optional)
+    — the node’s parent
+
+###### Returns
+
+Whether this is a node and passes a test (`node is Kind`).
+
+### `Test`
+
+Check for an arbitrary node, unaware of TypeScript inferral (TypeScript
+type).
+
+###### Type
+
+```ts
+type Test =
+  | null
+  | undefined
+  | string
+  | Record
+  | TestFunctionAnything
+  | Array | TestFunctionAnything>
+```
+
+Checks that the given thing is a node, and then:
+
+*   when `string`, checks that the node has that tag name
+*   when `function`, see  [`TestFunctionAnything`][testfunctionanything]
+*   when `object`, checks that all keys in test are in node, and that they have
+    (strictly) equal values
+*   when `Array`, checks if one of the subtests pass
+
+### `TestFunctionAnything`
+
+Check if a node passes a test, unaware of TypeScript inferral (TypeScript
+type).
+
+###### Parameters
+
+*   `node` ([`Node`][node])
+    — a node
+*   `index` (`number`, optional)
+    — the node’s position in its parent
+*   `parent` ([`Node`][node], optional)
+    — the node’s parent
+
+###### Returns
+
+Whether this node passes the test (`boolean`).
+
+### `PredicateTest`
+
+Check for a node that can be inferred by TypeScript (TypeScript type).
+
+###### Type
+
+```ts
+type PredicateTest =
+  | Kind['type']
+  | Partial
+  | TestFunctionPredicate
+  | Array | TestFunctionPredicate>
+```
+
+See [`TestFunctionPredicate`][testfunctionpredicate].
+
+### `TestFunctionPredicate`
+
+Check if a node passes a certain node test (TypeScript type).
+
+###### Type parameters
+
+*   `Kind` ([`Node`][node])
+    — node type
+
+###### Parameters
+
+*   `node` ([`Node`][node])
+    — a node
+*   `index` (`number`, optional)
+    — the node’s position in its parent
+*   `parent` ([`Node`][node], optional)
+    — the node’s parent
+
+###### Returns
+
+Whether this node passes the test (`node is Kind`).
+
+## Examples
+
+### Example of `convert`
+
+```js
+import {u} from 'unist-builder'
+import {convert} from 'unist-util-is'
+
+const test = convert('leaf')
+
+const tree = u('tree', [
+  u('node', [u('leaf', '1')]),
+  u('leaf', '2'),
+  u('node', [u('leaf', '3'), u('leaf', '4')]),
+  u('leaf', '5')
+])
+
+const leafs = tree.children.filter((child, index) => test(child, index, tree))
+
+console.log(leafs)
+```
+
+Yields:
+
+```js
+[{type: 'leaf', value: '2'}, {type: 'leaf', value: '5'}]
+```
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports the additional types [`AssertAnything`][assertanything],
+[`AssertPredicate`][assertpredicate], [`Test`][test],
+[`TestFunctionAnything`][testfunctionanything],
+[`TestFunctionPredicate`][testfunctionpredicate], and
+[`PredicateTest`][predicatetest].
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with all maintained
+versions of Node.js.
+As of now, that is Node.js 14.14+ and 16.0+.
+Our projects sometimes work with older versions, but this is not guaranteed.

+
+## What is this?
+
+This package is a utility that takes any [unist][] (whether mdast, hast, etc)
+node, position, or point, and serializes its positional info.
+
+## When should I use this?
+
+This utility is useful to display where something occurred in the original
+document, in one standard way, for humans.
+For example, when throwing errors or warning messages about something.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 14.14+ and 16.0+), install with [npm][]:
+
+```sh
+npm install unist-util-stringify-position
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {stringifyPosition} from 'https://esm.sh/unist-util-stringify-position@3'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import {stringifyPosition} from 'unist-util-stringify-position'
+
+stringifyPosition({line: 2, column: 3}) // => '2:3' (point)
+stringifyPosition({start: {line: 2}, end: {line: 3}}) // => '2:1-3:1' (position)
+stringifyPosition({
+  type: 'text',
+  value: '!',
+  position: {
+    start: {line: 5, column: 11},
+    end: {line: 5, column: 12}
+  }
+}) // => '5:11-5:12' (node)
+```
+
+## API
+
+This package exports the identifier [`stringifyPosition`][stringifyposition].
+There is no default export.
+
+### `stringifyPosition(node|position|point)`
+
+Serialize the positional info of a point, position (start and end points), or
+node.
+
+###### Parameters
+
+*   `node` ([`Node`][node])
+    — node whose `position` fields to serialize
+*   `position` ([`Position`][position])
+    — position whose `start` and `end` points to serialize
+*   `point` ([`Point`][point])
+    — point whose `line` and `column` fields to serialize
+
+###### Returns
+
+Pretty printed positional info of a node (`string`).
+
+In the format of a range `ls:cs-le:ce` (when given `node` or `position`) or a
+point `l:c` (when given `point`), where `l` stands for line, `c` for column, `s`
+for `start`, and `e` for end.
+An empty string (`''`) is returned if the given value is neither `node`,
+`position`, nor `point`.
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports no additional types.
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with all maintained
+versions of Node.js.
+As of now, that is Node.js 14.14+ and 16.0+.
+Our projects sometimes work with older versions, but this is not guaranteed.
+
+## Security
+
+This project is safe.

+## What is this?
+
+This is a very important utility for working with unist as it lets you walk the
+tree.
+
+## When should I use this?
+
+You can use this utility when you want to walk the tree and want to know about
+every parent of each node.
+You can use [`unist-util-visit`][unist-util-visit] if you don’t care about the
+entire stack of parents.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 14.14+ and 16.0+), install with [npm][]:
+
+```sh
+npm install unist-util-visit-parents
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {visitParents} from 'https://esm.sh/unist-util-visit-parents@5'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import {visitParents} from 'unist-util-visit-parents'
+import {fromMarkdown} from 'mdast-util-from-markdown'
+
+const tree = fromMarkdown('Some *emphasis*, **strong**, and `code`.')
+
+visitParents(tree, 'strong', (node, ancestors) => {
+  console.log(node.type, ancestors.map(ancestor => ancestor.type))
+})
+```
+
+Yields:
+
+```js
+strong ['root', 'paragraph']
+```
+
+## API
+
+This package exports the identifiers [`CONTINUE`][api-continue],
+[`EXIT`][api-exit], [`SKIP`][api-skip], and [`visitParents`][api-visitparents].
+There is no default export.
+
+### `visitParents(tree[, test], visitor[, reverse])`
+
+Visit nodes, with ancestral information.
+
+This algorithm performs *[depth-first][]* *[tree traversal][tree-traversal]*
+in *[preorder][]* (**NLR**) or if `reverse` is given, in *reverse preorder*
+(**NRL**).
+
+You can choose for which nodes `visitor` is called by passing a `test`.
+For complex tests, you should test yourself in `visitor`, as it will be
+faster and will have improved type information.
+
+Walking the tree is an intensive task.
+Make use of the return values of the visitor when possible.
+Instead of walking a tree multiple times, walk it once, use
+[`unist-util-is`][unist-util-is] to check if a node matches, and then perform
+different operations.
+
+You can change the tree.
+See [`Visitor`][api-visitor] for more info.
+
+###### Parameters
+
+*   `tree` ([`Node`][node])
+    — tree to traverse
+*   `test` ([`Test`][api-test], optional)
+    — [`unist-util-is`][unist-util-is]-compatible test
+*   `visitor` ([`Visitor`][api-visitor])
+    — handle each node
+*   `reverse` (`boolean`, default: `false`)
+    — traverse in reverse preorder (NRL) instead of the default preorder (NLR)
+
+###### Returns
+
+Nothing (`void`).
+
+### `CONTINUE`
+
+Continue traversing as normal (`true`).
+
+### `EXIT`
+
+Stop traversing immediately (`false`).
+
+### `SKIP`
+
+Do not traverse this node’s children (`'skip'`).
+
+### `Action`
+
+Union of the action types (TypeScript type).
+
+###### Type
+
+```ts
+type Action = typeof CONTINUE | typeof EXIT | typeof SKIP
+```
+
+### `ActionTuple`
+
+List with one or two values, the first an action, the second an index
+(TypeScript type).
+
+###### Type
+
+```ts
+type ActionTuple = [
+  (Action | null | undefined | void)?,
+  (Index | null | undefined)?
+]
+```
+
+### `BuildVisitor`
+
+Build a typed `Visitor` function from a tree and a test (TypeScript type).
+
+It will infer which values are passed as `node` and which as `parents`.
+
+###### Type parameters
+
+*   `Tree` ([`Node`][node], default: `Node`)
+    — tree type
+*   `Check` ([`Test`][api-test], default: `string`)
+    — test type
+
+###### Returns
+
+[`Visitor`][api-visitor].
+
+### `Index`
+
+Move to the sibling at `index` next (after node itself is completely
+traversed) (TypeScript type).
+
+Useful if mutating the tree, such as removing the node the visitor is currently
+on, or any of its previous siblings.
+Results less than `0` or greater than or equal to `children.length` stop
+traversing the parent.
+
+###### Type
+
+```ts
+type Index = number
+```
+
+### `Test`
+
+[`unist-util-is`][unist-util-is] compatible test (TypeScript type).
+
+### `Visitor`
+
+Handle a node (matching `test`, if given) (TypeScript type).
+
+Visitors are free to transform `node`.
+They can also transform the parent of node (the last of `ancestors`).
+
+Replacing `node` itself, if `SKIP` is not returned, still causes its
+descendants to be walked (which is a bug).
+
+When adding or removing previous siblings of `node` (or next siblings, in
+case of reverse), the `Visitor` should return a new `Index` to specify the
+sibling to traverse after `node` is traversed.
+Adding or removing next siblings of `node` (or previous siblings, in case
+of reverse) is handled as expected without needing to return a new `Index`.
+
+Removing the children property of an ancestor still results in them being
+traversed.
+
+###### Parameters
+
+*   `node` ([`Node`][node])
+    — found node
+*   `parents` ([`Array`][node])
+    — ancestors of `node`
+
+###### Returns
+
+What to do next.
+
+An `Index` is treated as a tuple of `[CONTINUE, Index]`.
+An `Action` is treated as a tuple of `[Action]`.
+
+Passing a tuple back only makes sense if the `Action` is `SKIP`.
+When the `Action` is `EXIT`, that action can be returned.
+When the `Action` is `CONTINUE`, `Index` can be returned.
+
+### `VisitorResult`
+
+Any value that can be returned from a visitor (TypeScript type).
+
+###### Type
+
+```ts
+type VisitorResult =
+  | Action
+  | ActionTuple
+  | Index
+  | null
+  | undefined
+  | void
+```
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports the additional types [`Action`][api-action],
+[`ActionTuple`][api-actiontuple], [`BuildVisitor`][api-buildvisitor],
+[`Index`][api-index], [`Test`][api-test], [`Visitor`][api-visitor], and
+[`VisitorResult`][api-visitorresult].
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with all maintained
+versions of Node.js.
+As of now, that is Node.js 14.14+ and 16.0+.
+Our projects sometimes work with older versions, but this is not guaranteed.

+## What is this?
+
+This is a very important utility for working with unist as it lets you walk the
+tree.
+
+## When should I use this?
+
+You can use this utility when you want to walk the tree.
+You can use [`unist-util-visit-parents`][vp] if you care about the entire stack
+of parents.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 14.14+ and 16.0+), install with [npm][]:
+
+```sh
+npm install unist-util-visit
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {visit} from 'https://esm.sh/unist-util-visit@4'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import {u} from 'unist-builder'
+import {visit} from 'unist-util-visit'
+
+const tree = u('tree', [
+  u('leaf', '1'),
+  u('node', [u('leaf', '2')]),
+  u('void'),
+  u('leaf', '3')
+])
+
+visit(tree, 'leaf', (node) => {
+  console.log(node)
+})
+```
+
+Yields:
+
+```js
+{type: 'leaf', value: '1'}
+{type: 'leaf', value: '2'}
+{type: 'leaf', value: '3'}
+```
+
+## API
+
+This package exports the identifiers [`CONTINUE`][api-continue],
+[`EXIT`][api-exit], [`SKIP`][api-skip], and [`visit`][api-visit].
+There is no default export.
+
+### `visit(tree[, test], visitor[, reverse])`
+
+This function works exactly the same as [`unist-util-visit-parents`][vp],
+but [`Visitor`][api-visitor] has a different signature.
+
+### `CONTINUE`
+
+Continue traversing as normal (`true`).
+
+### `EXIT`
+
+Stop traversing immediately (`false`).
+
+### `SKIP`
+
+Do not traverse this node’s children (`'skip'`).
+
+### `Action`
+
+Union of the action types (TypeScript type).
+See [`Action` in `unist-util-visit-parents`][vp-action].
+
+### `ActionTuple`
+
+List with an action and an index (TypeScript type).
+See [`ActionTuple` in `unist-util-visit-parents`][vp-actiontuple].
+
+### `BuildVisitor`
+
+Build a typed `Visitor` function from a tree and a test (TypeScript type).
+See [`BuildVisitor` in `unist-util-visit-parents`][vp-buildvisitor].
+
+### `Index`
+
+Move to the sibling at `index` next (TypeScript type).
+See [`Index` in `unist-util-visit-parents`][vp-index].
+
+### `Test`
+
+[`unist-util-is`][unist-util-is] compatible test (TypeScript type).
+
+### `Visitor`
+
+Handle a node (matching `test`, if given) (TypeScript type).
+
+Visitors are free to transform `node`.
+They can also transform `parent`.
+
+Replacing `node` itself, if `SKIP` is not returned, still causes its
+descendants to be walked (which is a bug).
+
+When adding or removing previous siblings of `node` (or next siblings, in
+case of reverse), the `Visitor` should return a new `Index` to specify the
+sibling to traverse after `node` is traversed.
+Adding or removing next siblings of `node` (or previous siblings, in case
+of reverse) is handled as expected without needing to return a new `Index`.
+
+Removing the children property of `parent` still results in them being
+traversed.
+
+###### Parameters
+
+*   `node` ([`Node`][node])
+    — found node
+*   `index` (`number` or `null`)
+    — index of `node` in `parent`
+*   `parent` ([`Node`][node] or `null`)
+    — parent of `node`
+
+###### Returns
+
+What to do next.
+
+An `Index` is treated as a tuple of `[CONTINUE, Index]`.
+An `Action` is treated as a tuple of `[Action]`.
+
+Passing a tuple back only makes sense if the `Action` is `SKIP`.
+When the `Action` is `EXIT`, that action can be returned.
+When the `Action` is `CONTINUE`, `Index` can be returned.
+
+### `VisitorResult`
+
+Any value that can be returned from a visitor (TypeScript type).
+See [`VisitorResult` in `unist-util-visit-parents`][vp-visitorresult].
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports the additional types [`Action`][api-action],
+[`ActionTuple`][api-actiontuple], [`BuildVisitor`][api-buildvisitor],
+[`Index`][api-index], [`Test`][api-test], [`Visitor`][api-visitor], and
+[`VisitorResult`][api-visitorresult].
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with all maintained
+versions of Node.js.
+As of now, that is Node.js 12.20+, 14.14+, 16.0+, and 18.0+.
+Our projects sometimes work with older versions, but this is not guaranteed.

+  uvu
+

+
+
+
+

+  uvu is an extremely fast and lightweight test runner for Node.js and the browser

+  Ultimate Velocity, Unleashed


+  example with suites
+

+
+
+## Features
+
+* Super [lightweight](https://npm.anvaka.com/#/view/2d/uvu)
+* Extremely [performant](#benchmarks)
+* Individually executable test files
+* Supports `async`/`await` tests
+* Supports native ES Modules
+* Browser-Compatible
+* Familiar API
+
+
+## Install
+
+```
+$ npm install --save-dev uvu
+```
+
+
+## Usage
+
+> Check out [`/examples`](/examples) for a list of working demos!
+
+```js
+// tests/demo.js
+import { test } from 'uvu';
+import * as assert from 'uvu/assert';
+
+test('Math.sqrt()', () => {
+  assert.is(Math.sqrt(4), 2);
+  assert.is(Math.sqrt(144), 12);
+  assert.is(Math.sqrt(2), Math.SQRT2);
+});
+
+test('JSON', () => {
+  const input = {
+    foo: 'hello',
+    bar: 'world'
+  };
+
+  const output = JSON.stringify(input);
+
+  assert.snapshot(output, `{"foo":"hello","bar":"world"}`);
+  assert.equal(JSON.parse(output), input, 'matches original');
+});
+
+test.run();
+```
+
+Then execute this test file:
+
+```sh
+# via `uvu` cli, for all `/tests/**` files
+$ uvu -r esm tests
+
+# via `node` directly, for file isolation
+$ node -r esm tests/demo.js
+```
+
+> **Note:** The `-r esm` is for legacy Node.js versions. [Learn More](/docs/esm.md)
+
+> [View the `uvu` CLI documentation](/docs/cli.md)
+
+
+## Assertions
+
+The [`uvu/assert`](/docs/api.assert.md) module is _completely_ optional.
+
+In fact, you may use any assertion library, including Node's native [`assert`](https://nodejs.org/api/assert.html) module! This works because `uvu` relies on thrown Errors to detect failures. Implicitly, this also means that any uncaught exceptions and/or unhandled `Promise` rejections will result in a failure, which is what you want!
+
+
+## API
+
+### Module: `uvu`
+
+> [View `uvu` API documentation](/docs/api.uvu.md)
+
+The main entry from which you will import the `test` or `suite` methods.
+
+### Module: `uvu/assert`
+
+> [View `uvu/assert` API documentation](/docs/api.assert.md)
+
+A collection of assertion methods to use within your tests. Please note that:
+
+* these are browser compatible
+* these are _completely_ optional
+
+
+## Benchmarks
+
+> via the [`/bench`](/bench) directory with Node v10.21.0
+
+Below you'll find each test runner with two timing values:
+
+* the `took ___` value is the total process execution time – from startup to termination
+* the parenthesis value (`(___)`) is the self-reported execution time, if known
+
+Each test runner's `stdout` is printed to the console to verify all assertions pass.
Said output is excluded below for brevity.
+
+```
+~> "ava"   took   594ms  (  ???  )
+~> "jest"  took   962ms  (356  ms)
+~> "mocha" took   209ms  (  4  ms)
+~> "tape"  took   122ms  (  ???  )
+~> "uvu"   took    72ms  (  1.3ms)
+```

+
+## What is this?
+
+This package provides a (lint) message format.
+
+## When should I use this?
+
+In most cases, you can use `file.message` from `VFile` itself, but in some
+cases you might not have a file, and still want to emit warnings or errors,
+in which case this can be used directly.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 14.14+ and 16.0+), install with [npm][]:
+
+```sh
+npm install vfile-message
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {VFileMessage} from 'https://esm.sh/vfile-message@3'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import {VFileMessage} from 'vfile-message'
+
+const message = new VFileMessage(
+  'Unexpected unknown word `braavo`, did you mean `bravo`?',
+  {line: 1, column: 8},
+  'spell:typo'
+)
+
+console.log(message)
+```
+
+Yields:
+
+```txt
+[1:8: Unexpected unknown word `braavo`, did you mean `bravo`?] {
+  reason: 'Unexpected unknown word `braavo`, did you mean `bravo`?',
+  line: 1,
+  column: 8,
+  source: 'spell',
+  ruleId: 'typo',
+  position: {start: {line: 1, column: 8}, end: {line: null, column: null}}
+}
+```
+
+## API
+
+This package exports the identifier [`VFileMessage`][api-vfile-message].
+There is no default export.
+
+### `VFileMessage(reason[, place][, origin])`
+
+Create a message for `reason` at `place` from `origin`.
+
+When an error is passed in as `reason`, the `stack` is copied.
+
+###### Parameters
+
+*   `reason` (`string` or `Error`)
+    — reason for message, uses the stack and message of the error if given
+*   `place` ([`Node`][node], [`Position`][position], or [`Point`][point],
+    optional)
+    — place in file where the message occurred
+*   `origin` (`string`, optional)
+    — place in code where the message originates (example:
+    `'my-package:my-rule'` or `'my-rule'`)
+
+###### Extends
+
+[`Error`][error].
+
+###### Returns
+
+Instance of `VFileMessage`.
+
+###### Fields
+
+*   `reason` (`string`)
+    — reason for message (you should use markdown)
+*   `fatal` (`boolean | null | undefined`)
+    — state of problem; `true` marks associated file as no longer processable
+    (error); `false` necessitates a (potential) change (warning);
+    `null | undefined` for things that might not need changing (info)
+*   `line` (`number | null`)
+    — starting line of error
+*   `column` (`number | null`)
+    — starting column of error
+*   `position` ([`Position | null`][position])
+    — full unist position
+*   `source` (`string | null`, example: `'my-package'`)
+    — namespace of message
+*   `ruleId` (`string | null`, example: `'my-rule'`)
+    — category of message
+*   `stack` (`string | null`)
+    — stack of message in code
+*   `file` (`string | null`)
+    — path of a file (used throughout the `VFile` ecosystem)
+
+### Well-known
+
+It’s OK to store custom data directly on the `VFileMessage`, some of those are
+handled by [utilities][util].
+The following fields are documented and typed here.
+
+###### Fields
+
+*   `actual` (`string | null`)
+    — specify the source value that’s being reported, which is deemed incorrect
+*   `expected` (`Array | null`)
+    — suggest acceptable values that can be used instead of `actual`
+*   `url` (`string | null`)
+    — link to docs for the message (this must be an absolute URL that can be
+    passed as `x` to `new URL(x)`)
+*   `note` (`string | null`)
+    — long form description of the message (you should use markdown)
+
+## Types
+
+This package is fully typed with [TypeScript][].
+It exports no additional types.
+
+## Compatibility
+
+Projects maintained by the unified collective are compatible with all maintained
+versions of Node.js.
+As of now, that is Node.js 14.14+ and 16.0+.
+Our projects sometimes work with older versions, but this is not guaranteed.
+

+
+## What is this?
+
+This package provides a virtual file format.
+It exposes an API to access the file value, path, metadata about the file, and
+specifically supports attaching lint messages and errors to certain places in
+these files.
+
+## When should I use this?
+
+The virtual file format is useful when dealing with the concept of files in
+places where you might not be able to access the file system.
+The message API is particularly useful when making things that check files (as
+in, linting).
+
+vfile is made for [unified][], which amongst other things checks files.
+However, vfile can be used in other projects that deal with parsing,
+transforming, and serializing data, to build linters, compilers, static site
+generators, and other build tools.
+
+This is different from the excellent [`vinyl`][vinyl] in that vfile has a
+smaller API, a smaller size, and focuses on messages.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 14.14 and 16.0+), install with [npm][]:
+
+```sh
+npm install vfile
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {VFile} from 'https://esm.sh/vfile@5'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import {VFile} from 'vfile'
+
+const file = new VFile({
+  path: '~/example.txt',
+  value: 'Alpha *braavo* charlie.'
+})
+
+console.log(file.path) // => '~/example.txt'
+console.log(file.dirname) // => '~'
+
+file.extname = '.md'
+
+console.log(file.basename) // => 'example.md'
+
+file.basename = 'index.text'
+
+console.log(file.history) // => ['~/example.txt', '~/example.md', '~/index.text']
+
+file.message('Unexpected unknown word `braavo`, did you mean `bravo`?', {
+  line: 1,
+  column: 8
+})
+
+console.log(file.messages)
+```
+
+Yields:
+
+```txt
+[
+  [~/index.text:1:8: Unexpected unknown word `braavo`, did you mean `bravo`?] {
+    reason: 'Unexpected unknown word `braavo`, did you mean `bravo`?',
+    line: 1,
+    column: 8,
+    source: null,
+    ruleId: null,
+    position: {start: [Object], end: [Object]},
+    file: '~/index.text',
+    fatal: false
+  }
+]
+```
+
+## API
+
+This package exports the identifier [`VFile`][api-vfile].
+There is no default export.
+
+### `VFile(options?)`
+
+Create a new virtual file.
+
+`options` is treated as:
+
+*   `string` or [`Buffer`][buffer] — `{value: options}`
+*   `URL` — `{path: options}`
+*   `VFile` — shallow copies its data over to the new file
+*   `object` — all fields are shallow copied over to the new file
+
+Path related fields are set in the following order (least specific to
+most specific): `history`, `path`, `basename`, `stem`, `extname`,
+`dirname`.
+
+You cannot set `dirname` or `extname` without setting either `history`,
+`path`, `basename`, or `stem` too.
+
+###### Parameters
+
+*   `options` ([`Compatible`][api-compatible], optional)
+    — file value
+
+###### Returns
+
+New instance (`VFile`).
+
+###### Example
+
+```js
+new VFile()
+new VFile('console.log("alpha");')
+new VFile(Buffer.from('exit 1'))
+new VFile({path: path.join('path', 'to', 'readme.md')})
+new VFile({stem: 'readme', extname: '.md', dirname: path.join('path', 'to')})
+new VFile({other: 'properties', are: 'copied', ov: {e: 'r'}})
+```
+
+### `file.value`
+
+Raw value ([`Buffer`][buffer], `string`, `null`).
+
+### `file.cwd`
+
+Base of `path` (`string`, default: `process.cwd()` or `'/'` in browsers).
+
+### `file.path`
+
+Get or set the full path (`string?`, example: `'~/index.min.js'`).
+
+Cannot be nullified.
+You can set a file URL (a `URL` object with a `file:` protocol) which will be
+turned into a path with [`url.fileURLToPath`][file-url-to-path].
+
+### `file.dirname`
+
+Get or set the parent path (`string?`, example: `'~'`).
+
+Cannot be set if there’s no `path` yet.
+
+### `file.basename`
+
+Get or set the basename (including extname) (`string?`, example: `'index.min.js'`).
+

+windows).
+Cannot be nullified (use `file.path = file.dirname` instead).
+
+### `file.extname`
+
+Get or set the extname (including dot) (`string?`, example: `'.js'`).
+
+Cannot contain path separators (`'/'` on unix, macOS, and browsers, `'\'` on
+windows).

+
+Serialize the file.
+
+###### Parameters
+
+*   `encoding` ([`BufferEncoding`][api-buffer-encoding], default: `'utf8'`)

+type Data = Record & Partial
+```
+
+### `DataMap`
+
+This map registers the type of the `data` key of a `VFile` (TypeScript type).
+
+This type can be augmented to register custom `data` types.
+
+###### Type
+
+```ts
+interface DataMap {}
+```
+
+###### Example
+
+```ts
+declare module 'vfile' {

+
+Configuration for reporters (TypeScript type).
+
+###### Type
+
+```ts
+type ReporterSettings = Record
+```
+

+
+Can either be text or a `Buffer` structure.
+
+###### Type
+
+```ts
+type Value = string | Buffer
+```
+
+### Well-known
+
+The following fields are considered “non-standard”, but they are allowed, and
+some utilities use them:
+
+*   `stored` (`boolean`)
+    — whether a file was saved to disk; this is used by vfile reporters
+*   `result` (`unknown`)
+    — custom, non-string, compiled, representation; this is used by unified to
+    store non-string results; one example is when turning markdown into React
+    nodes
+*   `map` ([`Map`][api-map])
+    — source map; this type is equivalent to the `RawSourceMap` type from the
+    `source-map` module
+
+There are also well-known fields on messages, see
+[them in a similar section of
+`vfile-message`](https://github.com/vfile/vfile-message#well-known).

+# which
+
+Like the unix `which` utility.
+
+Finds the first instance of a specified executable in the PATH
+environment variable.  Does not cache the results, so `hash -r` is not
+needed when the PATH changes.
+
+## USAGE
+
+```javascript
+const which = require('which')
+
+// async usage
+// rejects if not found
+const resolved = await which('node')
+
+// if nothrow option is used, returns null if not found
+const resolvedOrNull = await which('node', { nothrow: true })
+
+// sync usage
+// throws if not found
+const resolved = which.sync('node')
+
+// if nothrow option is used, returns null if not found
+const resolvedOrNull = which.sync('node', { nothrow: true })
+
+// Pass options to override the PATH and PATHEXT environment vars.
+await which('node', { path: someOtherPath, pathExt: somePathExt })
+```
+
+## CLI USAGE
+
+Just like the BSD `which(1)` binary but using `node-which`.
+
+```
+usage: node-which [-as] program ...
+```
+
+You can learn more about why the binary is `node-which` and not `which` 
+[here](https://github.com/npm/node-which/pull/67)
+
+## OPTIONS
+
+You may pass an options object as the second argument.
+
+- `path`: Use instead of the `PATH` environment variable.
+- `pathExt`: Use instead of the `PATHEXT` environment variable.
+- `all`: Return all matches, instead of just the first one.  Note that
+  this means the function returns an array of strings instead of a
+  single string.

+
+## What is this?
+
+This is a tiny package that lets you `switch` between some field on objects.
+
+## When should I use this?
+
+This package is very useful when mapping one AST to another.
+It’s a lot like a `switch` statement on one field, but it’s extensible.
+
+## Install
+
+This package is [ESM only][esm].
+In Node.js (version 14.14+, 16.0+), install with [npm][]:
+
+```sh
+npm install zwitch
+```
+
+In Deno with [`esm.sh`][esmsh]:
+
+```js
+import {zwitch} from 'https://esm.sh/zwitch@2'
+```
+
+In browsers with [`esm.sh`][esmsh]:
+
+```html
+
+```
+
+## Use
+
+```js
+import {zwitch} from 'zwitch'
+
+const handle = zwitch('type', {invalid, unknown, handlers: {alpha: handleAlpha}})
+
+handle({type: 'alpha'})
+
+function handleAlpha() { /* … */ }
+```
+
+Or, with a `switch` statement:
+
+```js
+const field = 'type'
+
+function handle(value) {
+  let fn = invalid
+
+  if (value && typeof value === 'object' && field in value) {
+    switch (value[field]) {
+      case 'alpha':
+        fn = handleAlpha
+        break
+      default:
+        fn = unknown
+        break
+    }
+  }
+
+  return fn.apply(this, arguments)
+}
+
+handle({type: 'alpha'})
+
+function handleAlpha() { /* … */ }
+function unknown() { /* … */ }
+function invalid() { /* … */ }
+```
+
+## API
+
+This package exports the identifier `zwitch`.
+There is no default export.
+
+### `zwitch(key[, options])`
+
+Create a switch, based on a `key` (`string`).
+

 # A common file format
 
-One of the core principals of OpenPipelines is to use [MuData](https://mudata.readthedocs.io/) as a common data format troughout the whole pipeline. This means that the input and output for most components and workflows will be a MuData file and converters from and to other common data formats are provided to improve compatibility with downstream applications. Choosing a common data format greatly diminishes the development complexity because it facilitates interfacing between different tools in a pipeline without needing to convert multiple times.
+One of the core principals of OpenPipelines is to use [MuData](https://mudata.readthedocs.io/) as a common data format troughout the whole pipeline. See [the concepts page](../fundamentals/concepts.qmd#sec-common-file-format) for more information on openpipelines uses MuData to store single-cell data.
 
-MuData is a format to store annotated multimodal data. It is derived from the [AnnData](https://anndata.readthedocs.io/en/latest/) format. If you are unfamiliar with AnnData or MuData, it is recommended to read up on AnnData first as it is the unimodal counterpart of MuData. MuData can be roughly described as collection of several AnnData objects (stored as a associative array in the `.mod` attribute). MuData provides a hierarchical way to store the data:
+# Component location
+As discussed in [the project structure](project_structure.qmd#sec-project-structure), components in the repository are stored within `src`. Additionally, components are grouped into namespaces, according to a common functionality. An example of such a namespace is the dimensionality reduction namespace (`dimred`), of which the components `pca` and `umap` are members. This means that within `src`, the namespace folders can be found that stores the components that belong to these namespaces. 
 
+In order to create a new component in OpenPipelines, you will need to create a new folder that will contain the different elements of the component:
+
+```bash
+mkdir src/my_namespace/my_component
 ```
-MuData
-├─ .mod
-│  ├─ modality_1 (AnnData Object)
-│     ├─ .X
-│     ├─ .layers
-│         ├─ layer_1 
-│         ├─ ...
-│     ├─ .var
-│     ├─ .obs

-├─ .obms

-├─ .uns
+
+:::{.callout-tip}
+Take a look at the components that are already in `src/`! There might be a component that already does something similar to what you need.
+:::
+
+# The elements of a component
+A component consists of one or more scripts that provide the functionality of the component together with metadata of the component in a configuration file. The [Viash config](https://viash.io/reference/config/) contains metadata of your dataset, which script is used to run it, and the required dependencies. An in-depth guide on how to create components is available on the [viash website](https://viash.io/guide/component/create-component.html), but a few specifics and guidelines will be discussed here.
+
+## The config
+
+```yaml
+functionality:
+  name: "my_component"
+  namespace: "my_namespace"
+  description: "My new custom component"
+  authors:
+    - __merge__: ../../authors/my_name.yaml
+      roles: [ author ]
+  arguments:
+    - name: "--output"
+      type: file
+      example: "output_file.h5mu"
+      description: "Location were the output file should be written to."
+      direction: "output"
+  resources:
+    - type: python_script
+      path: script.py
+platforms:
+  - type: docker
+    image: python:3.11
+    setup:
+      - type: python
+        packages: mudata~=0.2.3
+  - type: nextflow
+    directives:
+      label: [highcpu, midmem]
 ```
+### Basic information
+
+Each component should have the name, a namespace, a description and author information defined in the config. Because a single author can contribute to multiple components, the author information is often duplicated across components, which was causing issues with the author information being out of date and not easy to maintain. Therefore, it was decided to move author information to `./src/authors`. Each author has a `yaml` file containing the author information, and the viash `__merge__` property is used to merge this information into the viash configs.
+
+Basic information checklist:
+
+  - Give the component a name
+  - Add the component to an appropriate namespace
+  - Add a description
+  - Add author information
+
+### Arguments and argument groups
+
+If you component requires arguments, they should be defined in `arguments` or `argument_groups`. Try tro group individual arguments into `argument_groups` when the number of arguments become too larg  (10 or more as a rule of thumb). 
+
+Argument checklist:
+
+ - Add a description and name
+ - Each argument should have the appropriate type.
+ - Input and output files should be of type `file` instead of `string` and use the appropriate `direction:` 
+ - If possible: add an example
+ - If the argument can accept multiple values, add `multiple: true`
+ - If the possible input for an argument is limited to certain set of values, use `choices:`
+
+### (Test)resources
+
+Resources define files that are required for a component to perform its function. These can be scripts, but also additional files like settings for tools you might require. Defining resources is both a necessity because viash needs to know what code to execute, but defining resources also has the added benefit that these resources are automatically made available, regardless of the build environment. For example: resources are automatically mounted within a running docker container. 
+
+There is a difference between defining `resources` and `test_resources`. While resources are required for a component to function, `test_resources` only need to be included when testing the component (with for example `viash test`) in addition to the regular resources. Having a look at the example above, resources are defined using the `resources:` property. It takes a list of multiple files or folders.
+
+In openpipelines, it was decided to not use a service like `git lfs` to include large resources into the repository. Instead, if large resources are required, there are two possibilities:
+  * Large resources required for _testing_ are to uploaded into an `s3` bucket that is synced automatically before running tests (both locally and on github). Please ping a maintainer when you open a PR and ask them to upload the files for you.
+  * Other large resources that are not needed for testing can be considered as input. This means that an argument of `type: file` needs to be created. The downside of this method is that viash is not able to natively support remote files f
+
+Resources checklist:
+  - Script resources are located next to the config and added to the config with the correct type (`python_script`, `r_script`, ...)
+  - Small resources (<50MB) that are not scripts can also be checked in into the repo, next to the

 # Building components from their source
 When running or [testing individual components](#running-component-unittests), it is not necessary to execute an extra command to run the build step, `viash test` and `viash run` will build the component on the fly. However, before integrating components into a pipeline, you will need to build the components. More specifically, openpipelines uses Nextflow to combine components into pipelines, so we need to have at least the components build for `nextflow` platform as target. The easiest method to build the components is to use:

 As will become apparent later on, Viash not only provides commands to perform operations on individual components, but also on groups of components in a namespace and all components in a project.

 When cloning a fresh repository, there will be no `target` folder present. This is because the target folder will only be created after components have been build. 
 
-## Branching strategy
+## Versioning and branching strategy {#sec-versioning}
+
+OpenPipeline tries to use of [semantic versioning](https://semver.org/) to govern changes between versions. An release of openpipelines uses a version number in the format `MAJOR.MINOR.PATCH`. Currenly, openpipelines is still at major version `0.x.y`, meaning that public-facing breaking changes are possible on `MINOR` releases. These breaking changes will be documented in a dedicated section of the CHANGELOG that is published with each release. A `PATCH` release (i.e. a release where the `MAJOR` and `MINOR` version number stay the same), is used to resolve bugs with the pipeline but should not introduce breaking changes. Keep in mind that patches might introduce behavioral changes that may look breaking but are actually rectifying changes that were inadvertently introduced previously (and were in fact also 'breaking changes'). In this case, a bug can also be released without changing the `MINOR` version, in a `PATH` release.
+
+Between releases, development progress is tracked on Git branches. A git branch represents a snapshot of a codebase in time, to which changes can be added (i.e. committed). Eventually, all new feature or bugfixes must be reconsiled into a single branch so that a new release can be created. This process is called merging and the process of requesting the merging of two branches is called a pull request. Openpipelines follows the convention that the target branch for all pull requests is the `main` branch. Thus, the `main` branch contains the latest changes for the code and it can be considered the development branch.
+
+Once a pull request has been approved and merged, Github Actions CI will automatically build all components (creating the `target` directory) and push the result to the `main_build` branch. In essence, the `main_build` branch is a copy of the `main` branch, but also containing the build components. Once it is time to create a openpipelines release, the Github CI release workflow is manually triggered, the components on the `main` branch will be build and tested. Then, the result will be pushed to the `release` branch and the integration tests will be run. If all tests succeeded, a new github tag and release can be created manually from the `release` branch.

+OpenPipeline is a pipeline for the processing of multimodal single-cell data that scales to a great many of samples. Covering the architecture requires us to explain many angles, including: what the expected inputs and outputs are for each workflow are, how do the workflows relate to each other, and what the state of the data is at each step of the pipeline. Here is an overview of the general steps involved in processing sequencing data into a single integrated object. We will discuss each of the steps further below.

+1. [Ingestion](#ingestion): Convert raw sequencing data or count tables into MuData data for further processing.
+2. [Splitting modalities](#sec-splitting): Creating several MuData objects, one per modality, out of a multimodal input sample.
+3. [Unimodal Single Sample Processing](#sec-single-sample): tools applied to each modality of samples individually. Mostly involes the selection of true from false cells.
+4. [Unimodal Multi Sample Processing](#sec-multisample-processing): steps that require information from all samples together. Processing is still performed per-modality.
+5. [Merging](#sec-merging): Creating one MuData object from several unimodal MuData input files. 
+6. [Initializing Integration](#sec-initializing-integration): Performs dimensionality reduction and cell type clustering on non-integrated samples. These are popular steps that would otherwise be executed manually or they provide input for downstream integration methods.
+7. [Integration](#sec-intergration): The alignment of cell types across samples. Can be performed per modality or based on multiple modalities.
+8. Downstream Processing: Extra analyses performed on the integrated dataset and conversion to other file formats.
+
+# Available workflows
+The structure of the sections that have been laid out below follow a logical grouping of the processing according to the state _of the data_. However, even though this grouping makes sense from a data perspective, it does not mean that a workflow exist for each section. For example, the [processing a single sample](#sec-single-sample) section describes how processing of single sample is performed as part of the [full pipeline](#sec-full-pipeline), but there is no `singlesample` workflow that a user can execute. The inverse is also possible: while there exists an [multisample](../components/workflows/multiomics/mutlisample.qmd) pipeline, it's functionality is not limited to what has been described in the section [Multisample Processing](#sec-multisample-processing). This section lists all the available workflows and will try to describe the link with the relevant sections below.
+
+## Ingestion workflows
+All of the following workflows from the ingestion namespace have been discussed in more detail in the [ingestion](#sec-ingestion) section:
+
+* [ingestion/bd_rhapsody](../components/workflows/ingestion/bd_rhapsody.qmd)
+* [ingestion/cellranger_mapping](../components/workflows/ingestion/cellranger_mapping.qmd)
+* [ingestion/cellranger_multi](../components/workflows/ingestion/cellranger_multi.qmd)
+* [ingestion/demux](../components/workflows/ingestion/demux.qmd)
+* [ingestion/make_reference](../components/workflows/ingestion/make_reference.qmd) 
+
+
+## Multiomics workflows
+There exists no `singlesample` workflow. However, the `prot_singlesample` and `rna_singlesample` pipelines do exist and they map identically to the functionality described in the [single-sample antibody capture processing](#sec-single-sample-adt) and [single-sample gene expression processing](#sec-single-sample-gex) sections respectively. If you would like to process your samples as described in the [unimodal single sample processing](#sec-single-sample) section, you can execute both workflows in tandem for the two modalities.
+
+Contrary to the workflows for single sample processing, there exists a [multiomics/multisample](../components/workflows/multiomics/multisample.qmd) workflow. However this workflow is not just the [multiomics/prot_multisample](../components/workflows/multiomics/prot_multisample.qmd) and [multiomics/rna_multisample](../components/workflows/multiomics/rna_multisample.qmd) workflows that have been combined. Instead, it combines the [multiomics/prot_multisample](../components/workflows/multiomics/prot_multisample.qmd), [multiomics/rna_multisample](../components/workflows/multiomics/rna_multisample.qmd) and [multiomics/integration/initialize_integration](../components/workflows/multiomics/integration/initialize_integration.qmd) workflows. The purpose of this pipeline is to provide an extra 'entrypoint' into the full pipeline that skips the singlesample processing, allowing reprocessing samples that have already been processed before. A popular usecase is to manually select one or more celltypes which need to be processed again or the integration of observations from multiple experiments into a single dataset. Keep in mind that concatenation is not included in the multisample pipeline, so when multiple input files are specified they are processed in parallel. If you would like to integrate multiple experiments, you need to first concatenate them in a seperate step:
+
+```{.d2}
+file_input_1: "Experiment 1\n(multisample)" {
+  shape: page
+}
+

+concat -> multisample -> file_output
+
+style: {
+  fill: "#FCFCFC"
+}
+```
+
+## The "full" pipeline
+The name of this pipeline is a bit of a misnomer, because it does not include all the steps from ingestion to integration. As will be discussed in the [ingestion](#sec-ingestion) section, which ingestion strategy you need is dependant on your technology provider and the chosen platform. For [integration](#sec-integration-methods), there exist many methods and combination of methods, and you may wish to choose which integration methods are applicable for your usecase. As a consequence, these two stages in the analysis of single-cell need to be executed seperatly and not as part of a single unified pipeline. All other steps outlined below on the other hand are included into the "full" pipeline, which can therefore be summarized in the following figure:

+
+## Integration workflows
+For each of the integration methods (and their optional combination with other tools), a seperate pipeline is defined. More information for each of the pipelines is available in the [integration methods section](#sec-integration-methods).
+
+* [multiomics/integration/bbknn_leiden](../components/workflows/multiomics/integration/bbknn_leiden.qmd)

+
+# Important dataflow components
+While most components included in openpipelines are involved in data analysis, the sole purpose of other components is to facilitate data flow throughout the pipelines. In a workflow, output for a component is written to disk after it is done performing its task, and is read back in by the next component. However, the relation between the component and the next component is not always a clear one to one relationship. For example: some tools are capable of analyzing a single sample, while others require the input of all samples together. Additionally, not only are the input requirement of tools limiting, performance also needs to be taken into account. Tasks which are performed on each sample separately can be executed in parallel, while if the same task is performed on a single file that contains the data for all samples. In order to facilitate one-to-many or many-to-one relations between components and to allow parallel execution of tasks, component that are specialized in dataflow were implemented.  
+
+## Splitting modalities {#sec-splitting}
+We refer to splitting modalities when multimodal MuData file is split into several unimodal MuData files. The number of output files is equal to the number of modalities present in the input file. Splitting the modalities works on MuData files containing data for multiple samples or for single-sample files.

+## Concatenation of samples
+
+Joining of observations for different samples, stored in their respective MuData file, into a single MuData file for all samples together is called sample concatenation. In practice, this operation is performed for each modality separately. An extra column (with default name `sample_id`) is added to the annotation of the observations (`.obs`) to indicate where each observation originated from.

+Special care must be taken when considering annotations for observations and features while concatenating the samples. Indeed, the data from different samples can contain conflicting information. Openpipeline's `concat` component provides an argument `other_axis_mode` that allows a user to specify what happens when conflicting information is found. The `move` option for this argument is the default behavior. In this mode, each annotation column (from `.obs` and `.var`) is compared across samples. When no conflicts are found or the column is unique for a sample, the column is added output object. When a conflict does occur, all of the columns are gathered from the samples and stored into a dataframe. This dataframe is then stored into `.obsm` for annotations for the observations and `.varm` for feature annotations. This way, a user can have a look at the conflicts and decide what to do with them.

+The alignment of reads from the FASTQ files to an appropriate genome reference is called mapping. The result of the mapping process are tables that count the number of times a read has been mapped to a certain feature and metadata information for the cells (observations) and features. There are different format that can be used to store this information together. Since OpenPipeline uses [MuData](./concepts.qmd#sec-common-file-format) as a common file format throughout its pipelines, a conversion to MuData is included in the mapping pipelines.The choice between workflows for mapping is dependant on your single-cell library provider and technology:
 
-:::
+* For DB Genomics libraries, the [BD Rhapsody](../components/workflows/ingestion/bd_rhapsody.qmd) pipeline can be used.
+* For 10X based libraries, either [cellranger count](../components/workflows/ingestion/cellranger_mapping.qmd) or [cellranger multi](../components/workflows/ingestion/cellranger_multi.qmd) is provided. For more information about the differences between the two and when to use which mapping software, please consult the [10X genomics website](https://support.10xgenomics.com/single-cell-gene-expression/software/pipelines/latest/using/multi#when-to-use-multi).
 
-# Use-cases
+## Creating a transcriptomics reference
+Mapping reads from the FASTQ files to features requires a reference that needs to be provided to the mapping component. Depending on the usecase, you might even need to provide references specific for the modalities that you are trying to analyze. For gene expression data, the reference is a reference genome, together with its appropriate gene annotation. A genome reference is often indexed in order to improve the mapping speed. Additionally, some mapping frameworks provided by the single-cell technology providers require extra preprocessing of the reference before they can be used with their worklow. OpenPipelines provides a [make_reference](../components/workflows/ingestion/make_reference.qmd) that allows you to create references in many formats which can be used to map your reads to.
 
 
+# Processing a single sample {#sec-single-sample}
+Some processing can (or must) be performed without concatenating samples together. Even when having the choice, adding a tool to the single-sample processing is preferred because multiple samples can be processed in parallel, improving the processing speed. In general, the processing is modality specific, meaning that a multi-modal sample is first split into its unimodal counterparts. As described in the [multi-sample processing](#sec-multisample-processing), the resulting files are _not_ merged back together after the single-sample processing is done. Instead, the output files for all samples are gathered per modality and concatenated to create a multi-sample unimodal object.

+## Single-sample Gene Expression Processing {#sec-single-sample-gex}
+Single-sample gene expression processing involves two steps: removing cells based on count statistics and flagging observations originating from doublets. 
 
-```
+The removal of cells based on basic count statistics is split up into two parts: first, cells are flagged for removal by [filter_with_counts](../components/modules/filter/filter_with_counts.qmd). It flags observations based on several thresholds:
 
-:::
+* The number of genes that have a least a single count. Both a maximum and minimum number of genes for a cell to be removed can be specified.
+* The percentage of read counts that originated from a mitochodrial genes. Cells can be filtered based on both a maximum or minimum fraction of mitochondrial genes.
+* The minimum or maximum total number of counts captured per cell. Cells with 0 total counts are always removed.
 
+Flagging cells for removal involved adding a boolean column to the `.obs` dataframe. After the cells have been flagged for removal, the cells are actually filtered using [do_filter](../components/modules/filter/do_filter.qmd), which reads the values in `.obs` and removed the cells labeled `True`. This applies the general phylosophy of "separation of concerns": one component is responsible for labeling the cells, another for removing them. This keeps the codebase for a single component small and its functionality testable.
 
-### A single multimodal sample
+The next and final step in the single-sample gene expression processing is doublet detection using [filter_with_scrublet](../components/modules/filter/filter_with_scrublet.qmd). Like `filter_with_counts`, it will not remove cells but add a column to `.obs` (which have the name `filter_with_scrublet` by default). The single-sample GEX workflow will not remove not be removed during the processing (hence no `do_filter`). Howver, you can choose to remove them yourself before doing your analyses by applying a filter with the column in `.obs` yourself.

+# Multisample Processing {#sec-multisample-processing}
+After the processing of individual samples has been concluded, samples can be concatenated for further processing. Like with the single-sample processing the multisample processing is not performed on multimodal objects, but each modality separately in order to tailor for the specific modality in question. This means that the result from the singlesample processing is merged together per-modality to create unimodal multisample objects. After processing each modality, all of the modalities can finally be merged and a single object is created that is ready for the integration.

+
+## Multisample Gene Expression Processing
+Processing multisample gene expression involved the following steps:
+
+1. [Normalization](../components/modules/transform/normalize_total.qmd): Normalization aims to adjust the raw counts in the dataset for variable sampling effects by scaling the observable variance to a specified range. There are different ways to transform the data, but the normalization method is to make sure each observation (cell) has a total count equal to the median of total counts over all genes for observations (cells) before normalization.
+2. [Log transformation](../components/modules/transform/log1p.qmd): Calculates $X = ln(X + 1)$, which converts multiplicative relative changes to additive differences. This allows for interpreting the gene expression in terms of relative, rather than absolute, abundances of genes. 
+3. [Highly variable gene detection](../components/modules/filter/filter_with_hvg.qmd): Detects genes that have a large change in expression between samples. By default, OpenPipeline uses the method from Seurat [(Satija et al.)](https://doi.org/10.1038/nbt.3192). As with other "filtering" components, the `filter_with_hvg` component does not remove features, but rather annotates genes of interest by adding a boolean column to `.var`.

+
+## Dimensionality Reduction {#sec-dimensionality-reduction}
+scRNA-seq is a high-throughput sequencing technology that produces datasets with high dimensions in the number of cells and genes. It is true that the data should provide more information, but it also contains more noise and redudant information, making it harder to distill the usefull information. The number of genes and cells can already reduced by gene filtering, but further reduction is a necessity for downstream analysis. Dimensionality reduction projects high-dimensional data into a lower dimensional space (like taking a photo (2D) of some 3D structure). The lower dimensional representation still captures the underlying information of the data, while having fewer dimensions.
+
+Several dimensionality reduction methods have been developed and applied to single-cell data analysis. Two of which are being applied in OpenPipeline:
+
+1. [Principal Component Analysis (PCA)](../components/modules/dimred/pca.qmd): PCA reduces the dimension of a dataset by creating a new set of variables (principal components, PCs) from a linear combination of the original features in such a way that they are as uncorrelated as possible. The PCs can be ranked in the order by which they explain the largest variability in the original dataset. By keeping the top _n_ PCs, the PCs with the lowest variance are discarded to effectively reduce the dimensionality of the data without losing information.
+2. [Uniform manifold approximation and projection (UMAP)](../components/modules/dimred/umap.qmd): a non-linear dimensionality technique. It constructs a high dimensional graph representation of the dataset and optimizes the low-dimensional graph representation to be structurally as similar as possible to the original graph. In a review by [Xiang et al., 2021](https://doi.org/10.3389/fgene.2021.646936) it showed the highest stability and separates best the original cell populations.
+3. t-SNE is another popular non-linear, graph based dimensionality technique which is very similar to UMAP, but it has not yet been implemented in OpenPipeline.
+
+## Initializing integration {#sec-initializing-integration}
+As will be descibed in more details [later on](#sec-integration-methods), many integration methods exist and therefore there is no single integration which is executed by default. However, there are common tasks which are run before integration either because they provide required input for many downstream integration methods or because they popular steps that would otherwise be done manually. These operations _are_ executed by default when using the "full pipeline" as part of the [initialize_integration](../components/workflows/integration/initialize_integration/initialize_integration.qmd) subworkflow.
+
+[PCA](../components/modules/dimred/pca.qmd) is used to reduce the dimensionality of the dataset [as described previously](#sec-dimensionality-reduction). [Find Neighbors](../components/modules/neighbors/find_neighbors.qmd) and [Leiden Clustering](../components/modules/cluster/leiden.qmd) are useful for the identification of cell types or states in the data. Here we apply a popular method to accomplish this is to first calculate a neighborhood graph on a [low dimensinonal representation](#sec-dimensionality-reduction) of the data and then cluster the data based on similarity between data points. Finally, [UMAP](../components/modules/dimred/umap.qmd) allows us to visualise the clusters by reducing the dimensionality of the data while still providing an accurate representation of the underlying cell population structure.

+## Integration Mehods {#sec-integration-methods}
+Integration is the alignment of cell types across samples. There exist three different types of integration methods, based on the degree of integration across modalities:
+
+1. Unimodal integration across batches. For example: [scVI](../components/modules/integrate/scvi.qmd), [scanorama](../components/modules/integrate/scanorama.qmd), [harmony](../components/modules/integrate/harmonypy.qmd)
+2. Multimodal integration across batches and modalities. Can be used to integrate joint-profiling data where multiple modalities are measured. For example: [totalVI](../components/modules/integrate/totalvi.qmd)
+3. Mosaic integration: data integration across batches and modalities where not all cells are profiled in all modalities and it may be the case that no cells contain profiles in all integrated modalities. Mosaic integration methods have not been made available in OpenPipeline yet. An example of a tool that performs mosaic integration is StabMap.
+
+In either of the three cases, concatenated samples are required, and merged modalities preferred. A plethora of integration methods exist, which in turn interact with other functionality (like clustering and dimensionality reduction methods) to generate a large number of possible usecases which one pipeline cannot cover in an easy manner. Therefore, there is no single integration step that is part of a global pipeline which is executed by default. Instead, a user can choose from the integration workflows provided, and 'stack' integration methods by adding the outputs to different output slots of the MuData object. The following sections will descibe the integration workflows that are available in OpenPipeline.
+
+### Unimodal integration
+For unimodal integration, [scVI](../components/modules/integrate/scvi.qmd), [scanorama](../components/modules/integrate/scanorama.qmd) and [harmony](../components/modules/integrate/harmonypy.qmd) have been added to the [scvi_leiden](../components/workflows/integration/scvi_leiden.qmd), [scanorama_leiden](../components/workflows/integration/scanorama_leiden.qmd), and [harmony_leiden](../components/workflows/integration/harmony_leiden.qmd) workflows respectively. After executing the integration methods themselves, [Find Neighbors](../components/modules/neighbors/find_neighbors.qmd) and [Leiden Clustering](../components/modules/cluster/leiden.qmd) are run the results of the integration as wel as [UMAP](../components/modules/dimred/umap.qmd) in order to be able to visualise the results. The functioning of these components has already been described [here](#sec-initializing-integration).

+
+### Multimodal Integration
+A single multimodal integration method is currently avaiable in OpenPipeline: [totalVI](../components/modules/integrate/totalvi.qmd). It allows using information from both the gene-expression data and the antibody-capture data together to integrate the cell types. As with the other integration workflows, after running totalVI, [Find Neighbors](../components/modules/neighbors/find_neighbors.qmd), [Leiden Clustering](../components/modules/cluster/leiden.qmd) and [UMAP](../components/modules/dimred/umap.qmd) are run on the result. However in this case the three components are executed on both of the integrated modalities.

+# Goals
+
+OpenPipelines strives to provide easy ways to interact with the pipeline and/or codebase for three types of users:
+
+* Pipeline executor: runs the pipeline from a GUI side
+* Pipeline editor: adapts pipelines with existing components for specific projects
+* Component developer: develops novel components and or pipelines
+
+This means that openpipelines must be:
+
+* Usable by non-experts
+* Easy to deploy
+* Provide reproducable results
+* Scalable
+* Easy to maintain and adapt
+
+# Requirements
+
+To meet these demands, the following concepts have been implemented at the core of Openpipeline:
+
+* 🌍 A language independent framework
+* 💾 [A versitile storage solution](#sec-common-file-format)
+* 🔳 Modularity
+* 🔀 [A best-practice pipeline layout](architecture.qmd)
+* ⌛ [Versioning](../contributing/project_structure.qmd#sec-versioning)
+* ✅ [Automatic testing](../contributing/project_structure.qmd)
+* 💬 [Community input](../contributing/index.qmd)
+* 📺 A graphical interace
+
+# A common file format: AnnData and MuData 💾 {#sec-common-file-format}
+
+One of the core principals of OpenPipelines is to use [MuData](https://mudata.readthedocs.io/) as a common data format throughout the whole pipeline. This means that the input and output for most components and workflows will be a MuData file and converters from and to other common data formats are provided to improve compatibility with up-and downstream applications. Choosing a common data format greatly diminishes the development complexity because it facilitates interfacing between different tools in a pipeline without needing to convert multiple times.
+
+MuData is a format to store annotated multimodal data. It is derived from the [AnnData](https://anndata.readthedocs.io/en/latest/) format. If you are unfamiliar with AnnData or MuData, it is recommended to read up on AnnData first as it is the unimodal counterpart of MuData. MuData can be roughly described as collection of several AnnData objects (stored as a associative array in the `.mod` attribute). MuData provides a hierarchical way to store the data:
+
+```
+MuData
+├─ .mod
+│  ├─ modality_1 (AnnData Object)
+│     ├─ .X
+│     ├─ .layers
+│         ├─ layer_1 
+│         ├─ ...
+│     ├─ .var
+│     ├─ .obs
+│     ├─ .obsm
+│     ├─ .varm
+│     ├─ .uns
+│  ├─ modality_1 (AnnData Object)
+├─ .var
+├─ .obs
+├─ .obms
+├─ .varm
+├─ .uns
+```
+
+* `.mod`: an associative array of AnnData objects. Used in OpenPipelines to store the different modalities (CITE-seq, RNA abundance, ...)
+* `.X` and `.layers`: matrices storing the measurements with the columns being the variables measured and the rows being the observations (cells in most cases).
+* `.var`: metadata for the variables (i.e. annotation for the columns of `.X` or any matrix in `.layers`). The number of rows in the .var datafame (or the length of each entry in the dictionairy) is equal to the number of columns in the measurement matrices. 
+* `.obs`: metadata for the observations (i.e. annotation for the rows of `.X` or any matrix in `.layers`). The number of rows in the .obs datafame (or the length of each entry in the dictionairy) is equal to the number of rows in the measurement matrices.
+* `varm`: multi-dimensional the variable annotation. A key-dataframe mapping where the number of rows in each dataframe is equal to the number of columns in the measurement matrices.
+* `obsm`: multi-dimensional the observation annotation. A key-dataframe mapping where the number of rows in each dataframe is equal to the number of rows in the measurement matrices.
+* `.uns`: A mapping where no restrictions are enforced on the dimensions of the data.

+# Mission
+
+OpenPipelines are best-practice living workflows for single-cell uni- and multi-omics data. Building a best-practice pipeline requires knowledge and time that not one single person can provide, but rather requires input from a community. Additionally, a best-pratice pipeline needs constant maintenance to keep up to date with the latest standards, ideally sourcing input from a 'living' benchmark. Continuous improvement necessitates a robust system for sourcing and applying community input both from a technical and organisational standpoint.
