Auto configurations for Language Server for vim-lsp

Language Servers is not easy to install. Visual Studio Code provide easy way to install/update Language Server and Language Server Client. This plugin provide same feature on Vim.

For vim-plug plugin manager:

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

You need to install both vim-lsp and its accompanying plugins and vim-lsp-settings.

If you want to use autocompletion plugin, you can use followings.

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

Plug 'Shougo/deoplete.nvim'
Plug 'lighttiger2505/deoplete-vim-lsp'

If you use plugin manager that is merging plugins (ex. dein), Please setting stop merging work(ex. dein / merged = 0) or set g:lsp_settings_servers_dir option to a different directory from the vim-lsp's default.

reason:

vim-lsp-settings install Language Servers into:

%LOCALAPPDATA%\vim-lsp-settings\servers

$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.

While editing a file with a supported filetype:

:LspInstallServer

To uninstall server:

:LspUninstallServer

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

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

If you install rls already, you can use rls without configurations. But if you not installed rls yet, you can install it by following this instruction.

To use gql-language-server, .gqlconfig have to be located on the top of project directory. And 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

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.

Most of configurations are not required.

If you install clangd already, you can use clangd for C/C++ without configurations. But if you install clang with named clangd-6.0, you can replace executable like below:

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

Or put .vim-lsp-settings/settings.json on 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 three parts: the path to your 'dart' executable, the path to your 'analysis_server.dart.snapshot', and the '--lsp' flag.

let g:lsp_settings = {
    \ 'analysis_server.dart.snapshot': {
    \     'cmd': [
    \         '/path/to/your/dart-sdk/bin/dart',
    \         '/path/to/your/dart-sdk/bin/bin/snapshots/analysis_server.dart.snapshot',
    \         '--lsp'
    \     ],
    \ },
\ }

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

Overridable keys are:

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

If you install ruby but not solargraph, you can install solargraph with following command.

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_typescript = ['typescript-language-server', 'eslint-language-server']

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

If you want to disable 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.
