Make use of a special .github directory for README
* Moved .assets to .github/assets, as they are supposed to be used in web-based viewers * Removed images from the project level README file Utilizes GitHub's features for a special directory ".github". GitHub overrides the project level README if it finds one in the ".github" directory, allowing to make a separate READMEs for terminals and the web.

Zig Language Server, or `zls`, is a language server for Zig. The Zig wiki states that "The Zig community is decentralized" and "There is no concept of 'official' or 'unofficial'", so instead of calling `zls` unofficial, and I'm going to call it a cool option, one of [many](https://github.com/search?q=zig+language+server).

|
||||
## Installation
|
||||
|
||||
Installation starts with downloading an official release from the [Releases page](https://github.com/zigtools/zls/releases).
|
||||
|
||||
See [Downloading and Building ZLS](https://github.com/zigtools/zls/wiki/Downloading-and-Building-ZLS) on the Wiki, or the page about [using ZLS with Visual Studio Code](https://github.com/zigtools/zls/wiki/Installing-for-Visual-Studio-Code) for a guide to help get `zls` running in your editor.
|
||||
|
||||
### From Source
|
||||
|
||||
Building `zls` is very easy. You will need [a build of Zig master](https://ziglang.org/download/) to build zls.
|
||||
|
||||
```bash
|
||||
git clone --recurse-submodules https://github.com/zigtools/zls
|
||||
cd zls
|
||||
zig build -Drelease-safe
|
||||
zig build config # Configure ZLS
|
||||
```
|
||||
|
||||
*For detailed building instructions, see the Wiki page about [Cloning With Git](https://github.com/zigtools/zls/wiki/Downloading-and-Building-ZLS#cloning-with-git).*
|
||||
|
||||
#### Build Options
|
||||
|
||||
<!-- When updating this table, be sure to copy changes to the Wiki page about building from source. -->
|
||||
<!-- If this table grows too large, then delete this one and move it all over to the Wiki page about building from source. -->
|
||||
| Option | Type | Default Value | What it Does |
|
||||
| --- | --- | --- | --- |
|
||||
| `-Ddata_version` | `string` (master or 0.7.0) | master | The data file version. This selects the files in the `src/data` folder that correspond to the Zig version being served.|
|
||||
|
||||
### Configuration Options
|
||||
|
||||
You can configure zls by providing a zls.json file.
|
||||
zls will look for a zls.json configuration file in multiple locations with the following priority:
|
||||
- In the local configuration folder of your OS (as provided by [known-folders](https://github.com/ziglibs/known-folders#folder-list))
|
||||
- In the same directory as the executable
|
||||
|
||||
The following options are currently available.
|
||||
|
||||
| Option | Type | Default value | What it Does |
|
||||
| --- | --- | --- | --- |
|
||||
| `enable_snippets` | `bool` | `false` | Enables snippet completions when the client also supports them. |
|
||||
| `zig_lib_path` | `?[]const u8` | `null` | zig library path, e.g. `/path/to/zig/lib/zig`, used to analyze std library imports. |
|
||||
| `zig_exe_path` | `?[]const u8` | `null` | zig executable path, e.g. `/path/to/zig/zig`, used to run the custom build runner. If `null`, zig is looked up in `PATH`. Will be used to infer the zig standard library path if none is provided. |
|
||||
| `warn_style` | `bool` | `false` | Enables warnings for style *guideline* mismatches |
|
||||
| `build_runner_path` | `?[]const u8` | `null` | Path to the build_runner.zig file provided by zls. `null` is equivalent to `${executable_directory}/build_runner.zig` |
|
||||
| `build_runner_cache_path` | `?[]const u8` | `null` | Path to a directroy that will be used as zig's cache when running `zig run build_runner.zig ...`. `null` is equivalent to `${KnownFloders.Cache}/zls` |
|
||||
| `enable_semantic_tokens` | `bool` | `true` | Enables semantic token support when the client also supports it. |
|
||||
| `operator_completions` | `bool` | `true` | Enables `*` and `?` operators in completion lists. |
|
||||
|
||||
## Features
|
||||
|
||||
`zls` supports most language features, including simple type function support, usingnamespace, payload capture type resolution, custom packages and others.
|
||||
Notable language features that are not currently implemented include `@cImport` as well as most forms of compile time evaluation.
|
||||
|
||||
The following LSP features are supported:
|
||||
- Completions
|
||||
- Hover
|
||||
- Goto definition/declaration
|
||||
- Document symbols
|
||||
- Find references
|
||||
- Rename symbol
|
||||
- Formatting using `zig fmt`
|
||||
- Semantic token highlighting (LSP 3.16 proposed feature, implemented by a few clients including VSCode, kak and emacs lsp-mode)
|
||||
|
||||
You can install `zls` using the instuctions for your text editor below:
|
||||
|
||||
### VSCode
|
||||
|
||||
Install the `zls-vscode` extension from [here](https://github.com/zigtools/zls-vscode/releases) and provide a path to the build `zls` executable.
|
||||
|
||||
### Sublime Text 3
|
||||
|
||||
- Install the `LSP` package from [here](https://github.com/sublimelsp/LSP/releases) or via Package Control.
|
||||
- Add this snippet to `LSP's` user settings:
|
||||
|
||||
```json
|
||||
{
|
||||
"clients": {
|
||||
"zig":{
|
||||
"command": ["zls"],
|
||||
"enabled": true,
|
||||
"languageId": "zig",
|
||||
"scopes": ["source.zig"],
|
||||
"syntaxes": ["Packages/Zig Language/Syntaxes/Zig.tmLanguage"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Kate
|
||||
|
||||
- Enable `LSP client` plugin in Kate settings.
|
||||
- Add this snippet to `LSP client's` user settings (e.g. /$HOME/.config/kate/lspclient)
|
||||
(or paste it in `LSP client's` GUI settings)
|
||||
|
||||
```json
|
||||
{
|
||||
"servers": {
|
||||
"zig": {
|
||||
"command": ["zls"],
|
||||
"url": "https://github.com/zigtools/zls",
|
||||
"highlightingModeRegex": "^Zig$"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Neovim/Vim8
|
||||
#### CoC
|
||||
|
||||
- Install the CoC engine from [here](https://github.com/neoclide/coc.nvim).
|
||||
- Issue `:CocConfig` from within your Vim editor, and the following snippet:
|
||||
|
||||
```json
|
||||
{
|
||||
"languageserver": {
|
||||
"zls" : {
|
||||
"command": "command_or_path_to_zls",
|
||||
"filetypes": ["zig"]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### nvim-lspconfig
|
||||
Requires Nvim 0.5 (HEAD)!
|
||||
|
||||
- Install nvim-lspconfig from [here](https://github.com/neovim/nvim-lspconfig).
|
||||
- Install zig.vim from [here](https://github.com/ziglang/zig.vim).
|
||||
|
||||
nvim-lspconfig already ships a configuration for zls. A simple `init.vim` might look like this:
|
||||
```vim
|
||||
call plug#begin('~/.config/nvim/plugged')
|
||||
Plug 'neovim/nvim-lspconfig'
|
||||
Plug 'nvim-lua/completion-nvim'
|
||||
Plug 'ziglang/zig.vim'
|
||||
call plug#end()
|
||||
|
||||
:lua << EOF
|
||||
local lspconfig = require('lspconfig')
|
||||
|
||||
local on_attach = function(_, bufnr)
|
||||
vim.api.nvim_buf_set_option(bufnr, 'omnifunc', 'v:lua.vim.lsp.omnifunc')
|
||||
require('completion').on_attach()
|
||||
end
|
||||
|
||||
local servers = {'zls'}
|
||||
for _, lsp in ipairs(servers) do
|
||||
lspconfig[lsp].setup {
|
||||
on_attach = on_attach,
|
||||
}
|
||||
end
|
||||
EOF
|
||||
|
||||
" Set completeopt to have a better completion experience
|
||||
set completeopt=menuone,noinsert,noselect
|
||||
|
||||
" Enable completions as you type
|
||||
let g:completion_enable_auto_popup = 1
|
||||
```
|
||||
|
||||
|
||||
### Emacs
|
||||
|
||||
- Install [lsp-mode](https://github.com/emacs-lsp/lsp-mode) from melpa
|
||||
- [zig mode](https://github.com/ziglang/zig-mode) is also useful
|
||||
|
||||
```elisp
|
||||
(require 'lsp)
|
||||
(add-to-list 'lsp-language-id-configuration '(zig-mode . "zig"))
|
||||
(lsp-register-client
|
||||
(make-lsp-client
|
||||
:new-connection (lsp-stdio-connection "<path to zls>")
|
||||
:major-modes '(zig-mode)
|
||||
:server-id 'zls))
|
||||
```
