Install ZLS

Note If you only intend to use Visual Studio Code, you don't need to install ZLS or Zig manually

Prebuilt Binaries

Latest

Note We currently recommend using the latest binaries as Zig and ZLS are fast-evolving.

	x86-64	AArch64	x86
Linux	x86-64 Linux	AArch64 Linux	x86 Linux
Windows	x86-64 Windows	-	x86 Windows
MacOS	x86-64 Macos	AArch64 MacOS	-

Release

Head to the Releases tab and select the right executable in the Assets section at the bottom of the latest release.

tar  -x --strip-components=1 -f [archive] [output_path]

From Source

See this section in the README.

Install Editor Extension

Most extensions expect you to either manually specify the path to ZLS or add ZLS to your PATH

Visual Studio Code

Note You don't need to install ZLS or Zig manually

Using ZLS in Visual Studio Code is as simple as installing the official Zig Language extension (open in VSCode).

Sublime Text

1. install the LSP and sublime-zig-language package (Package Control Usage)
2. place the following snippet in the LSP.sublime-settings (Preferences -> Package Settings -> LSP -> Settings)
3. place the following snippet in the Zig.sublime-settings (Preferences -> Package Settings -> Zig -> Settings)

// Zig.sublime-settings
{
	// ZLS will run format on save
	"zig.fmt.on_save": false,
        // automatically hide the build/fmt output panel 
	"zig.quiet": true,
}

Sublime Text 4

// LSP.sublime-settings
{
    // General settings
    "lsp_format_on_save": true,
    "lsp_code_actions_on_save": {
      "source.fixAll": true,
    },
    "show_inlay_hints": true,
    "semantic_highlighting": true,

    // Language server configurations
    "clients": {
        "zig": {
            // the startup command -- what you would type in a terminal
            "command": ["/path/to/zls_executable"],
            // enable this configuration
            "enabled": true,
            // the selector that selects which type of buffers this language server attaches to
            "selector": "source.zig"
        }
    }
}

Sublime Text 3

// LSP.sublime-settings
{
    "clients": {
        "zig": {
            "command": ["/path/to/zls_executable"],
            "enabled": true,
            "languageId": "zig",
            "scopes": ["source.zig"],
            "syntaxes": ["Packages/Zig Language/Syntaxes/Zig.tmLanguage"]
        }
    }
}

Neovim / Vim8

CoC

With Extension

Run :CocInstall coc-zls to install coc-zls. This extension supports the same functionality as the VS Code extension.

Manually

{
    "languageserver": {
        "zls" : {
            "command": "/path/to/zls_executable",
            "filetypes": ["zig"]
        }
    }
}

YouCompleteMe

• Install YouCompleteMe from here.
• Add these lines to your vimrc:

"ensure zig is a recognized filetype
autocmd BufNewFile,BufRead *.zig set filetype=zig
let g:ycm_language_server =
    \\ [
    \\{
    \\     'name': 'zls',
    \\     'filetypes': [ 'zig' ],
    \\     'cmdline': [ '/path/to/zls_executable' ]
    \\    }
    \\ ]

nvim-lspconfig

Requires Nvim 0.5 (HEAD)!

• Install nvim-lspconfig from here.
• Install zig.vim from here.

nvim-lspconfig already ships a configuration for zls. A simple init.vim might look like this:

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

LanguageClient-neovim

• Install the LanguageClient-neovim from here.
• Edit your neovim configuration and add zls for zig filetypes:

let g:LanguageClient_serverCommands = {
        \\ 'zig': ['/path/to/zls_executable'],
        \\ }

Kate

• Install language support for Zig from here.
• 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)

{
    "servers": {
        "zig": {
            "command": ["/path/to/zls_executable"],
            "url": "https://github.com/zigtools/zls",
            "highlightingModeRegex": "^Zig$"
        }
    }
}

Emacs

• Install lsp-mode from melpa.
• zig mode is also useful.

;; Setup lsp-mode as desired.
;; See https://emacs-lsp.github.io/lsp-mode/page/installation/ for more information.
(require 'lsp-mode)
;; Either place zls in your PATH or add the following:
(setq lsp-zig-zls-executable "/path/to/zls_executable")

Doom Emacs

• Enable :tools lsp module.
• Enable :lang (zig +lsp) module.
• Run doom sync in a terminal.

Spacemacs

• Add lsp and zig to dotspacemacs-configuration-layers in your .spacemacs file.
• If you don't have zls in your PATH, add the following to dotspacemacs/user-config in your .spacemacs file:

(setq lsp-zig-zls-executable "/path/to/zls_executable")

Helix

Add zls to your PATH or manually specify the path in <config_dir>/helix/languages.toml with the following:

[language-server.zls]
command = "/path/to/zls_executable"

Further information on languages.toml files

Then run hx --health to check if helix found zls.
