codeium.vim

Free, ultrafast Copilot alternative for Vim and Neovim

Codeium autocompletes your code with AI in all major IDEs. We launched this implementation of the Codeium plugin for Vim and Neovim to bring this modern coding superpower to more developers. Check out our playground if you want to quickly try out Codeium online.

Contributions are welcome! Feel free to submit pull requests and issues related to the plugin.

🚀 Getting started

Install Vim (at least 9.0.0185) or Neovim (at least 0.6)
Install Exafunction/codeium.vim using your vim plugin manager of choice, or manually. See Installation Options below.
Run :Codeium Auth to set up the plugin and start using Codeium.

You can run :help codeium for a full list of commands and configuration options, or see this guide for a quick tutorial on how to use Codeium.

🛠️ Configuration

For a full list of configuration options you can run :help codeium. A few of the most popular options are highlighted below.

⌨️ Keybindings

Codeium provides the following functions to control suggestions:

Action	Function	Default Binding
Clear current suggestion	`codeium#Clear()`	`<C-]>`
Next suggestion	`codeium#CycleCompletions(1)`	`<M-]>`
Previous suggestion	`codeium#CycleCompletions(-1)`	`<M-[>`
Insert suggestion	`codeium#Accept()`	`<Tab>`
Manually trigger suggestion	`codeium#Complete()`	`<M-Bslash>`
Accept word from suggestion	`codeium#AcceptNextWord()`	`<C-k>`
Accept line from suggestion	`codeium#AcceptNextLine()`	`<C-l>`

Codeium's default keybindings can be disabled by setting

let g:codeium_disable_bindings = 1

or in Neovim:

vim.g.codeium_disable_bindings = 1

If you'd like to just disable the <Tab> binding, you can alternatively use the g:codeium_no_map_tab option.

If you'd like to bind the actions above to different keys, this might look something like the following in Vim:

imap <script><silent><nowait><expr> <C-g> codeium#Accept()
imap <script><silent><nowait><expr> <C-h> codeium#AcceptNextWord()
imap <script><silent><nowait><expr> <C-j> codeium#AcceptNextLine()
imap <C-;>   <Cmd>call codeium#CycleCompletions(1)<CR>
imap <C-,>   <Cmd>call codeium#CycleCompletions(-1)<CR>
imap <C-x>   <Cmd>call codeium#Clear()<CR>

Or in Neovim (using wbthomason/packer.nvim or folke/lazy.nvim):

-- Remove the `use` here if you're using folke/lazy.nvim.
use {
  'Exafunction/codeium.vim',
  config = function ()
    -- Change '<C-g>' here to any keycode you like.
    vim.keymap.set('i', '<C-g>', function () return vim.fn['codeium#Accept']() end, { expr = true, silent = true })
    vim.keymap.set('i', '<c-;>', function() return vim.fn['codeium#CycleCompletions'](1) end, { expr = true, silent = true })
    vim.keymap.set('i', '<c-,>', function() return vim.fn['codeium#CycleCompletions'](-1) end, { expr = true, silent = true })
    vim.keymap.set('i', '<c-x>', function() return vim.fn['codeium#Clear']() end, { expr = true, silent = true })
  end
}

(Make sure that you ran :Codeium Auth after installation.)

⛔ Disabling Codeium

Codeium can be disabled for particular filetypes by setting the g:codeium_filetypes variable in your vim config file (vimrc/init.vim):

let g:codeium_filetypes = {
    \ "bash": v:false,
    \ "typescript": v:true,
    \ }

Codeium is enabled by default for most filetypes.

You can also disable codeium by default with the g:codeium_enabled variable, and enable it manually per buffer by running :CodeiumEnable:

let g:codeium_enabled = v:false

or in Neovim:

vim.g.codeium_enabled = false

Or you can disable codeium for all filetypes with the g:codeium_filetypes_disabled_by_default variable, and use the g:codeium_filetypes variable to selectively enable codeium for specified filetypes:

" let g:codeium_enabled = v:true
let g:codeium_filetypes_disabled_by_default = v:true

let g:codeium_filetypes = {
    \ "rust": v:true,
    \ "typescript": v:true,
    \ }

If you would like to just disable the automatic triggering of completions:

let g:codeium_manual = v:true

" You might want to use `CycleOrComplete()` instead of `CycleCompletions(1)`.
" This will make the forward cycling of suggestions also trigger the first
" suggestion manually.
imap <C-;> <Cmd>call codeium#CycleOrComplete()<CR>

To disable automatic text rendering of suggestions (the gray text that appears for a suggestion):

let g:codeium_render = v:false

Show Codeium status in statusline

Codeium status can be generated by calling the codeium#GetStatusString() function. In Neovim, you can use vim.api.nvim_call_function("codeium#GetStatusString", {}) instead. It produces a 3 char long string with Codeium status:

'3/8' - third suggestion out of 8
'0' - Codeium returned no suggestions
'*' - waiting for Codeium response

In normal mode, status shows if Codeium is enabled or disabled by showing 'ON' or 'OFF'.

In order to show it in status line add following line to your .vimrc:

set statusline+=\{…\}%3{codeium#GetStatusString()}

Shorter variant without Codeium logo:

set statusline+=%3{codeium#GetStatusString()}

Please check :help statusline for further information about building statusline in VIM.

vim-airline supports Codeium out-of-the-box since commit 3854429d.

Launching Codeium Chat

Calling the codeium#Chat() function will enable search and indexing in the current project and launch Codeium Chat in a new browser window.

:call codeium#Chat()

The project root is determined by looking in Vim's current working directory for some specific files or directories to be present and goes up to parent directories until one is found. This list of hints is user-configurable and the default value is:

let g:codeium_workspace_root_hints = ['.bzr','.git','.hg','.svn','_FOSSIL_','package.json']

Note that launching chat enables telemetry.
