Microsoft language server protocol implementation for D.
This program is the heart of code-d and implements most IDE features in D.
The purpose of this project is to give every editor the same capabilities and editing features as code-d through the widely available Microsoft Language Server Protocol (LSP).

This implements most language features of the language server protocol for D and also a lot of support for other D related files such as vibe.d diet files and DlangUI DML files.
To use serve-d you will need an Editor (client) with support for the Language Server Protocol. Depending on the editor the initialization code might look different and will need to be adapted for each editor. This is relatively small though and can be done easily for all editors.
Officially Supported Editors
add LSP configurations using serve-d for other editors and PR them here!

serve-d offers the following command line options to allow the LSP client to configure serve-d on startup:
| Option | Default | Description |
|---|---|---|
-r / --require |
[] | (allows multiple, optional) List of options which this serve-d version needs to implement. serve-d will intentionally crash on startup if one of the given options is not supported by this version. Specifying or not specifying them will not change anything on runtime. Implemented features: d (PoC / unneeded), workspaces (multi-workspace support) |
-p / --provide |
[] | (allows multiple, optional) List of options to affect behavior of serve-d. Use this to indicate support for special editor features/extensions not covered by the LSP spec. Supported values: (see provides list below) |
-v / --version |
n/a | Prints the version to stdout and exists |
--logfile |
n/a | Overrides the logging output to log to a file instead of stderr for debug logs |
--loglevel |
verbose for debug/nightly builds, otherwise info |
Changes the minimum log level when messages are logged. See serve-d --help for possible values |
--lang |
en |
Changes the language of GUI messages to a supported translation |
--wait |
false |
Waits for one second before starting (useful to be able to attach when debugging) |
The following provide values are supported by serve-d and will improve interop with the editor:
--provide http
When this provide flag is set, serve-d will send a request to the client when it wants to download a file (commonly DCD server files) using the coded/interactiveDownload request.
If this is not set, an internal download function is used which calls coded/logInstall on the client on every progress event.
--provide implement-snippets
If this is set, the served/implementMethods request will return TextEdits with snippet strings inside of them as defined by vscode.
--provide context-snippets --provide default-snippets
If this is set, auto completion requests will also return built-in and custom defined snippets. Will register snippets for popular DUB dependencies that are built into serve-d.
NOTE: these flags will be enabled by default in serve-d v0.9.0 and become obsolete then.
serve-d defines a variety of custom requests and notifications for better editor integration. All requests starting with coded/ are sent from serve-d to the client and all requests starting with served/ are sent from client to serve-d at any time.
serve-d internally handles an active instance which is the instance where last a relevant command has been run. (such as auto complete) It will be used for some commands.

If you use an existing extension (code-d) you will not need to do these steps
If you want to manually get the serve-d binaries or if you want to add installation support for your editor, check out the sections below. The extension code-d already does this automatically and there is no need to do it there.
Installing a pre-built binary:
Grab latest stable ore pre-release with binaries from GitHub releases
Grab latest nightly binaries from GitHub releases
Manually building from source:
dub build
If you have issues with any editors using serve-d, please report an issue
