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, follow the installation steps for your chosen plugin manager:

::Tabs

:::TabTitle No plugin manager

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

:::TabTitle 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,
    },
  },
}

:::TabTitle packer.nvim

Declare the plugin in your packer.nvim configuration:

use {
  "git@gitlab.com:gitlab-org/editor-extensions/gitlab.vim.git",
}

::EndTabs

Configure the extension

Configure environment variables. While these are the most common, a full list is available in this plugin's help text at doc/gitlab.txt:

Environment variable	Default	Description
`GITLAB_TOKEN`.	not applicable	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`.

Configure your desired file types. For example, because this plugin supports Ruby, it adds a FileType ruby auto-command. To configure this behavior for additional file types, add more file types to the code_suggestions.auto_filetypes setup option:

require('gitlab').setup({
  statusline = {
    enabled = false
  },
  code_suggestions = {
    # For the full list of default languages, see the 'auto_filetypes' array in
    # https://gitlab.com/gitlab-org/editor-extensions/gitlab.vim/-/blob/main/lua/gitlab/config/defaults.lua 
    auto_filetypes = { 'ruby', 'javascript' }, -- Default is { 'ruby' }
  }
})

Optional. Configure Omni Completion.
Optional. Configure <Plug> key mappings.
Optional. Set up helptags using :helptags ALL for access to :help gitlab.txt.

Configure Omni Completion

To enable Omni Completion with Code Suggestions:

Create a personal access token with the api scope.
Install the Code Suggestions language server.
Optional. Consider configuring Omni Completion's dialog even for a single suggestion:
```
vim.o.completeopt = 'menu,menuone'
```

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

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)')

Disable `gitlab.statusline`

By default, this plugin enables gitlab.statusline, which uses the built-in statusline to show the status of the Code Suggestions integration. If you want to disable gitlab.statusline, add this to your configuration:

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