GitLab plugin for Neovim - gitlab.vim

The GitLab plugin integrates GitLab with Neovim, and is built in Lua.

GitLab for Neovim supports GitLab Duo Code Suggestions. Code Suggestions provides a LSP (Language Server Protocol) server, to support the built-in Control+x, Control+o Omni Completion key mapping:

Mode Key mappings Type Description
INSERT Control+x, Control+o Built-in Requests completions from GitLab Duo Code Suggestions through the language server.
NORMAL <Plug>(GitLabToggleCodeSuggestions) <Plug> Toggles Code Suggestions on or off for the current buffer. Requires configuration.

Install the extension

Prerequisites:

  • For both GitLab.com and self-managed, you have GitLab version 16.1 or later. While many extension features might work with earlier versions, they are unsupported.
    • The GitLab Duo Code Suggestions feature requires GitLab version 16.8 or later.
  • You have Neovim version 0.9 or later.

To install the extension:

  1. Follow the installation steps for your chosen plugin manager.
  2. Optional. Configure GitLab Duo Code Suggestions as an Omni Completion provider.
  3. Set up helptags using :helptags ALL for access to :help gitlab.txt.

Run this command to include this project with packadd on startup: 

git clone git@gitlab.com:gitlab-org/editor-extensions/gitlab.vim.git ~/.local/share/nvim/site/pack/gitlab/start/gitlab.vim
lazy.nvim

Add this plugin to your lazy.nvim configuration: 

{
  'git@gitlab.com:gitlab-org/editor-extensions/gitlab.vim.git',
  -- Activate when a file is created/opened
  event = { 'BufReadPre', 'BufNewFile' },
  -- Activate when a supported filetype is open
  ft = { 'go', 'javascript', 'python', 'ruby' },
  cond = function()
    -- Only activate if token is present in environment variable.
    -- Remove this line to use the interactive workflow.
    return vim.env.GITLAB_TOKEN ~= nil and vim.env.GITLAB_TOKEN ~= ''
  end,
  opts = {
    statusline = {
      -- Hook into the built-in statusline to indicate the status
      -- of the GitLab Duo Code Suggestions integration
      enabled = true,
    },
  },
}
packer.nvim

Configure the extension

These environment variables are frequently used with the extension. For a full list, see this plugin’s help text at doc/gitlab.txt.

Environment variable Default Description
GITLAB_TOKEN. n/a The default GitLab personal access token to use for authenticated requests. If provided, skips interactive authentication.
GITLAB_VIM_URL. https://gitlab.com Override the GitLab instance to connect with. Defaults to https://gitlab.com.

This plugin enables gitlab.statusline by default, which hooks into the built-in statusline to show the status of the Code Suggestions integration. To disable gitlab.statusline, add this to your configuration: 

require('gitlab').setup({
  statusline = {
    enabled = false
  }
})

Configure Omni Completion

To enable Omni Completion with Code Suggestions:

  1. Create a personal access token with the api scope.

  2. Install the Code Suggestions language server.

  3. Optional. Consider configuring Omni Completion’s dialog even for a single suggestion: 

    vim.o.completeopt = 'menu,menuone'

When working in a supported file type, press Ctrl+x then Ctrl+o to open the Omni Completion menu.

Configure <Plug> key mappings

For convenience, this plugin provides <Plug> key mappings. To use the <Plug>(GitLab...) key mapping, you must include your own key mapping that references it: 

-- Toggle Code Suggestions on/off with CTRL-g in normal mode:
vim.keymap.set('n', '<C-g>', '<Plug>(GitLabToggleCodeSuggestions)')
