# nvim-lsp

Collection of common configurations for the [Nvim LSP client](https://neovim.io/doc/user/lsp.html).

It is hoped that these configurations serve as a "source of truth", but they
are strictly _best effort_. If something doesn't work, these configs are useful
as a starting point, which you can adjust to fit your environment.

This is work-in-progress and **requires [Nvim HEAD/nightly](https://github.com/neovim/neovim/releases/tag/nightly)**.
Update Nvim and nvim-lsp before reporting an issue.

## Contributions are welcome!

There are many language servers in the world, and not enough time.
Help us create configs for *all the LSPs!*

1. Read [CONTRIBUTING.md](CONTRIBUTING.md) for instructions.
   Ask questions in [Neovim Gitter](https://gitter.im/neovim/neovim).
2. Choose a language from [the coc.nvim wiki](https://github.com/neoclide/coc.nvim/wiki/Language-servers) or
  [the emacs-lsp project](https://github.com/emacs-lsp/lsp-mode#supported-languages).
3. Create a new file at `lua/nvim_lsp/SERVER_NAME.lua`. See
   [existing configs](https://github.com/neovim/nvim-lsp/blob/master/lua/nvim_lsp/) for
   examples (`lua/nvim_lsp/texlab.lua` is an extensive example).

## Install

- Requires [Nvim HEAD/nightly](https://github.com/neovim/neovim/releases/tag/nightly) (v0.5 prerelease).
- nvim-lsp is just a plugin. Install it like any other Vim plugin.

  e.g. [vim-plug](https://github.com/junegunn/vim-plug)
  ```
  :Plug 'neovim/nvim-lsp'
  ```
- Call `:packadd nvim-lsp` in your vimrc if you installed nvim-lsp to
  `'packpath'` or if you use a package manager such as minpac.

## Usage

Each config provides a `setup()` function, to initialize the server with
reasonable defaults and some server-specific things like commands or different
diagnostics.

    vim.cmd('packadd nvim-lsp')
    require'nvim_lsp'.<config>.setup{name=…, settings = {…}, …}

Find the [config](#configurations) for your language, then paste the example
given there to your `init.vim`. **All examples are given in Lua,** see `:help
:lua-heredoc` to use Lua from your init.vim.

Some configs may define additional server-specific functions, e.g. the `texlab`
config provides `nvim_lsp.texlab.buf_build({bufnr})`.

### Example: using the defaults

To use the defaults, just call `setup()` with an empty `config` parameter.
For the `gopls` config, that would be:

    vim.cmd('packadd nvim-lsp')
    require'nvim_lsp'.gopls.setup{}

### Example: override some defaults

To set some config properties at `setup()`, specify their keys. For example to
change how the "project root" is found, set the `root_dir` key:

```lua
local nvim_lsp = require'nvim_lsp'
nvim_lsp.gopls.setup{
  root_dir = nvim_lsp.util.root_pattern('.git');
}
```

The [documentation](#configurations) for each config lists default values and
additional optional properties.

```lua
local nvim_lsp = require'nvim_lsp'
nvim_lsp.texlab.setup{
  name = 'texlab_fancy';
  log_level = vim.lsp.protocol.MessageType.Log;
  message_level = vim.lsp.protocol.MessageType.Log;
  settings = {
    latex = {
      build = {
        onSave = true;
      }
    }
  }
}
```

### Example: custom config

To configure a custom/private server, just require `nvim_lsp/configs` and do
the same as we do if we were adding it to the repository itself.

1. Define the config: `configs.foo_lsp = { … }`
2. Call `setup()`: `require'nvim_lsp'.foo_lsp.setup{}`

```lua
local nvim_lsp = require'nvim_lsp'
local configs = require'nvim_lsp/configs'
-- Check if it's already defined for when I reload this file.
if not nvim_lsp.foo_lsp then
  configs.foo_lsp = {
    default_config = {
      cmd = {'/home/ashkan/works/3rd/lua-language-server/run.sh'};
      filetypes = {'lua'};
      root_dir = function(fname)
        return nvim_lsp.util.find_git_ancestor(fname) or vim.loop.os_homedir()
      end;
      settings = {};
    };
  }
end
nvim_lsp.foo_lsp.setup{}
```

### Example: orverride default config

If you want to change default configs for all servers, you can override default_config like this.

```lua
local nvim_lsp = require'nvim_lsp'
nvim_lsp.util.default_config = vim.tbl_extend(
  "force",
  nvim_lsp.util.default_config,
  { log_level = lsp.protocol.MessageType.Warning.Error }
)
```

### Installing a language server

Configs may provide an `install()` function. Then you can use
`:LspInstall {name}` to install the required language server.
For example, to install the Elm language server:

    :LspInstall elmls

Use `:LspInstallInfo` to see install info.

    :LspInstallInfo

## setup() function

The `setup()` interface:

```
nvim_lsp.SERVER.setup{config}

  The `config` parameter has the same shape as that of
  |vim.lsp.start_client()|, with these additions and changes:

  {root_dir}
    Required for some servers, optional for others.
    Function of the form `function(filename, bufnr)`.
    Called on new candidate buffers being attached-to.
    Returns either a root_dir or nil.

    If a root_dir is returned, then this file will also be attached. You
    can optionally use {filetype} to help pre-filter by filetype.

    If a root_dir is returned which is unique from any previously returned
    root_dir, a new server will be spawned with that root_dir.

    If nil is returned, the buffer is skipped.

    See |nvim_lsp.util.search_ancestors()| and the functions which use it:
    - |nvim_lsp.util.root_pattern(patterns...)| finds an ancestor which
    - contains one of the files in `patterns...`. This is equivalent
      to coc.nvim's "rootPatterns"
    - Related utilities for common tools:
      - |nvim_lsp.util.find_git_root()|
      - |nvim_lsp.util.find_node_modules_root()|
      - |nvim_lsp.util.find_package_json_root()|

  {name}
    Defaults to the server's name.

  {filetypes}
    Set of filetypes to filter for consideration by {root_dir}.
    May be empty.
    Server may specify a default value.

  {log_level}
    controls the level of logs to show from window/logMessage notifications. Defaults to
    vim.lsp.protocol.MessageType.Warning instead of
    vim.lsp.protocol.MessageType.Log.

  {message_level}
    controls the level of messages to show from window/showMessage notifications. Defaults to
    vim.lsp.protocol.MessageType.Warning instead of
    vim.lsp.protocol.MessageType.Log.

  {settings}
    Map with case-sensitive keys corresponding to `workspace/configuration`
    event responses.
    We also notify the server *once* on `initialize` with
    `workspace/didChangeConfiguration`.
    If you change the settings later on, you must emit the notification
    with `client.workspace_did_change_configuration({settings})`
    Example: `settings = { keyName = { subKey = 1 } }`

  {on_attach}
    `function(client)` executed with the current buffer as the one the {client}
    is being attached-to. This is different from
    |vim.lsp.start_client()|'s on_attach parameter, which passes the {bufnr} as
    the second parameter instead. Useful for doing buffer-local setup.

  {on_new_config}
    `function(new_config)` will be executed after a new configuration has been
    created as a result of {root_dir} returning a unique value. You can use this
    as an opportunity to further modify the new_config or use it before it is
    sent to |vim.lsp.start_client()|.

```lua
require'nvim_lsp'.bashls.setup{}

  Default Values:
    cmd = { "bash-language-server", "start" }
    filetypes = { "sh" }
    root_dir = vim's starting directory
```

## ccls

https://github.com/MaskRay/ccls/wiki

ccls relies on a [JSON compilation database](https://clang.llvm.org/docs/JSONCompilationDatabase.html) specified
as compile_commands.json or, for simpler projects, a compile_flags.txt.

This server accepts configuration via the `settings` key.
<details><summary>Available settings:</summary>

- **`ccls.cache.directory`**: `string`

  Default: `".ccls-cache"`
  
  Absolute or relative (from the project root) path to the directory that the cached index will be stored in. Try to have this directory on an SSD. If empty, cached indexes will not be saved on disk.
  
  ${workspaceFolder} will be replaced by the folder where .vscode/settings.json resides.
  
  Cache directories are project-wide, so this should be configured in the workspace settings so multiple indexes do not clash.
  
  Example value: "/work/ccls-cache/chrome/"

- **`ccls.cache.hierarchicalPath`**: `boolean`

  If false, store cache files as $directory/@a@b/c.cc.blob
  
  If true, $directory/a/b/c.cc.blob.

- **`ccls.callHierarchy.qualified`**: `boolean`

  Default: `true`
  
  If true, use qualified names in the call hiearchy

- **`ccls.clang.excludeArgs`**: `array`

  Default: `{}`
  
  An set of command line arguments to strip before passing to clang when indexing. Each list entry is a separate argument.

- **`ccls.clang.extraArgs`**: `array`

  Default: `{}`
  
  An extra set of command line arguments to give clang when indexing. Each list entry is a separate argument.

- **`ccls.clang.pathMappings`**: `array`

  Default: `{}`
  
  Translate paths in compile_commands.json entries, .ccls options and cache files. This allows to reuse cache files built otherwhere if the source paths are different.

- **`ccls.clang.resourceDir`**: `string`

  Default: `""`
  
  Default value to use for clang -resource-dir argument. This will be automatically supplied by ccls if not provided.

- **`ccls.codeLens.enabled`**: `boolean`

  Default: `true`
  
  Specifies whether the references CodeLens should be shown.

- **`ccls.codeLens.localVariables`**: `boolean`

  Set to false to hide code lens on parameters and function local variables.

- **`ccls.codeLens.renderInline`**: `boolean`

  Enables a custom code lens renderer so code lens are displayed inline with code. This removes any vertical-space footprint at the cost of horizontal space.

- **`ccls.completion.caseSensitivity`**: `integer`

  Default: `2`
  
  Case sensitivity when code completion is filtered. 0: case-insensitive, 1: case-folded, i.e. insensitive if no input character is uppercase, 2: case-sensitive

- **`ccls.completion.detailedLabel`**: `boolean`

  When this option is enabled, the completion item label is very detailed, it shows the full signature of the candidate.

- **`ccls.completion.duplicateOptional`**: `boolean`

  For functions with default arguments, generate one more item per default argument.

- **`ccls.completion.include.suffixWhitelist`**: `array`

  Default: `{ ".h", ".hpp", ".hh" }`
  
  Only files ending in one of these values will be shown in include auto-complete. Set to the empty-list to disable include auto-complete.

- **`ccls.completion.include.whitelist`**: `array`

  Default: `{}`
  
  ECMAScript regex that checks absolute file path. If it does not partially match, the file is not added to include path auto-complete. An example is "/src/"

  Default: `vim.NIL`
  
  The maximum number of global search (ie, Ctrl+P + #foo) search results to report. For small search strings on large projects there can be a massive number of results (ie, over 1,000,000) so this limit is important to avoid extremely long delays. null means use the default value provided by the ccls language server.

## sumneko_lua

https://github.com/sumneko/lua-language-server

Lua language server. **By default, this doesn't have a `cmd` set.** This is
because it doesn't provide a global binary. We provide an installer for Linux
and macOS using `:LspInstall`.  If you wish to install it yourself, [here is a
guide](https://github.com/sumneko/lua-language-server/wiki/Build-and-Run).
So you should set `cmd` yourself like this.

```lua
require'nvim_lsp'.sumneko_lua.setup{
  cmd = {"path", "to", "cmd"};
  ...
}
```

If you install via our installer, if you execute `:LspInstallInfo sumneko_lua`, you can know `cmd` value.

Can be installed in Nvim with `:LspInstall sumneko_lua`
This server accepts configuration via the `settings` key.
