vim-lsp-settings

Auto configurations for Language Servers for vim-lsp.

Introduction

Language Servers are not easy to install. Visual Studio Code provides easy ways to install and update Language Servers and Language Server Client. This plugin provides the same feature for Vim.

Installation

Using the vim-plug plugin manager:

Plug 'prabirshrestha/vim-lsp'
Plug 'mattn/vim-lsp-settings'

You need to install both vim-lsp and vim-lsp-settings.

Usage

While editing a file with a supported filetype:

:LspInstallServer

To uninstall server:

:LspUninstallServer server-name

Because there is no way to update a server, please run :LspInstallServer again, the newer version will be installed.

Auto-complete

If you want to use auto-completion, you can use one of the following.

asyncomplete.vim

Plug 'prabirshrestha/asyncomplete.vim'
Plug 'prabirshrestha/asyncomplete-lsp.vim'

ddc.vim

Plug 'Shougo/ddc.vim'
Plug 'shun/ddc-vim-lsp'

LSP server download directory

This is where LSP servers are placed on your system after you download them with :LspInstallServer

Windows

%LOCALAPPDATA%\vim-lsp-settings\servers

MacOS/Linux

$HOME/.local/share/vim-lsp-settings/servers

If you define $XDG_DATA_HOME:

$XDG_DATA_HOME/vim-lsp-settings/servers

You can change the directory to install servers by set g:lsp_settings_servers_dir option in full path.

Notes

clangd (C/C++)

There is a Linux OS/version that does not run the locally installed clangd due to zlib version mismatch. If you want to use clangd, please install clangd on your system.

rls (Rust)

If you installed rls already, you can use rls without configurations. But if you have not installed rls yet, you can install it by following these instructions.

deno (TypeScript)

To use deno, deno.json(c) should located on the project directory or traversing the filesystem upwards.

If deno.json does not located, node_modules should not located on the project directory or traversing the filesystem upwards.

When editing Node projects, the following warning message is shown.

server "deno" is disabled since "node_modules" is found

If you want to disable warning message, you may put .vim-lsp-settings/settings.json in your project root directory.

{
  "deno": {
    "disabled": true
  }
}

To use importMap, default file name is import_map.json.

If you don't want to use import_map.json, you may put .vim-lsp-settings/settings.json in your project root directory and set importMap whatever you want.

{
  "deno": {
    "initialization_options": {
      "enable": true,
      "lint": true,
      "unstable": true,
      "importMap": "your_own_import_map.json"
    }
  }
}

Recommend to add let g:markdown_fenced_languages = ['ts=typescript'] to your vimrc for hover(preview) Deno's library.

Note that deno language server is specified.

let g:lsp_settings_filetype_typescript = ['typescript-language-server', 'eslint-language-server', 'deno']

flow (JavaScript)

To use flow, the .flowconfig has to be located on the top of project directory.

graphql-language-service-cli(GraphQL)

To use graphql-language-service-cli, the GraphQL Config has to be located on the top of project directory. The schema must be pointed to the schema file correctly.

{
  "schema": "./schema.graphql"
}

gql-language-server (GraphQL)

To use gql-language-server, the .gqlconfig has to be located on the top of project directory. The schema must be pointed to the schema file correctly.

{
  schema: {
    files: 'path/to/schema.graphql'
  }
}

Finally, you have to install @playlyfe/gql into your project.

$ npm install @playlyfe/gql --save-dev

dart analysis server (Dart)

If you have a separate existing installation of the dart analysis server and want it to be used, it must either exist in your path, or you must specify its location. See 'Configurations' below.

haskell ide engine (Haskell)

If you installed hie with stack, you can use hie without configurations. But if you have not installed hie yet, you can install it by following these steps.

golangci-lint-langserver (Go)

To use older version golangci-lint, please run :LspSettingsGlobalEdit and put bellow configuration.

"golangci-lint-langserver": {
    "initialization_options": {
        "command": [
            "golangci-lint", "run", "--enable-all", "--disable", "lll", "--out-format", "json"
        ]
    }
}

Extra Configurations

Most of the configurations are not required.

If you installed clangd already, you can use clangd for C/C++ without any configuration. But if you installed clang with the name clangd-6.0, you can replace executable with the following config:

let g:lsp_settings = {
\  'clangd': {'cmd': ['clangd-6.0']},
\  'efm-langserver': {'disabled': v:false}
\}

Or put .vim-lsp-settings/settings.json in your project root directory.

{
  "clangd": {
    "cmd": ["clangd-6.0"]
  },
  "efm-langserver": {
    "disabled": false
  }
}

If you already have the dart analysis server installed but it is not in your path, you can still configure the settings to use it. Use the vimscript below to change the command to start the server. Note the command has two parts: the path to your 'dart' executable, and a subcommand 'language-server.

let g:lsp_settings = {
    \ 'analysis-server-dart-snapshot': {
    \     'cmd': [
    \         '/path/to/your/dart-sdk/bin/dart',
    \         'language-server'
    \     ],
    \ },
\ }

To edit the project local settings.json, do :LspSettingsLocalEdit.

Overridable keys are:

• cmd (List ex: ['clangd-6.0', '-enable-snippets'])
• initialization_options (Dictionary)
• allowlist (List)
• blocklist (List)
• config (Dictionary)
• workspace_config (Dictionary)
• disabled (Boolean)
• root_uri (String)
• root_uri_patterns (List)
• semantic_highlight (Dictionary)

If you have some Language Servers and want to use specified the server:

let g:lsp_settings_filetype_perl = 'slp'
let g:lsp_settings_filetype_html = ['html-languageserver', 'angular-language-server']
let g:lsp_settings_filetype_typescript = ['typescript-language-server', 'eslint-language-server']

When the servers are specified in a list, these will all be started.

If you want to configure Language Server to use flake8 rather than pycodestyle, the following can be added to your ~/.vimrc file. Note that pylsp-all was the automatically registered server name. Check with :LspStatus.

let g:lsp_settings = {
\   'pylsp-all': {
\     'workspace_config': {
\       'pylsp': {
\         'configurationSources': ['flake8']
\       }
\     }
\   },
\}

If you want to disable a Language Server:

let g:lsp_settings = {
\  'perl-languageserver': {
\    'disabled': 1,
\   }
\}

When resolving the root directory for a language server, this plugin will look for directories containing special root markers defined in g:lsp_settings_root_markers.

By default, this is set to:

let g:lsp_settings_root_markers = [
\   '.git',
\   '.git/',
\   '.svn',
\   '.hg',
\   '.bzr'
\ ]

If you need to specify alternative root markers:

let g:lsp_settings_root_markers = ['.projections.json', '.git', '.git/']

This would look for a custom .projections.json, a git submodule .git or a git root .git/ starting from the current directory upwards.
