Keymaps for Codeium

[UnclePsymon]

Hey there! I want to set the keybinds for Codeium, but i can't get them to work.

This is from my old lua config:

vim.g.codeium_disable_bindings = 1
vim.keymap.set('i', '<C-u>', function () return vim.fn['codeium#Accept']() end, { expr = true })
vim.keymap.set('i', '<c-h>', function() return vim.fn['codeium#CycleCompletions'](1) end, { expr = true })
vim.keymap.set('i', '<c-l>', function() return vim.fn['codeium#CycleCompletions'](-1) end, { expr = true })
vim.keymap.set('i', '<c-k>', function() return vim.fn['codeium#Clear']() end, { expr = true })

I tried it like that, but that did not work:

keymaps = [
  {
    action = "<cmd>codeium#CycleCompletitions<CR>";
    key = "<C-u>";
    mode = "i";
    options = { 
      desc = "Codeium Cycle Completitions";
      expr = true;
    };
];

Can you tell me how to do it? ❤️

In your first example you are defining lua functions as your rhs (action), while in your nixvim example you are not.

Probably better to port what you had before exactly before attempting to optimise it:

keymaps = [
  {
    action.__raw = "function() return vim.fn['codeium#Accept']() end";
    key = "<C-u>";
    mode = "i";
    options = { 
      desc = "Codeium Cycle Completitions";
      expr = true;
    };
  }
];

I think action.__raw = "vim.fn['codeium#Accept']" would also work.

IDK if the lua function wrapping a vim function is strictly necessary, it should be possible to use the vim fn directly as you proposed <cmd>codeium#CycleCompletitions<CR>, but better to try one thing at a time.

Have you tried calling the function directly from vim's command mode (without a keymapping)?

:codeium#CycleCompletitions

The only other question is; is codeium actually enabled and loaded?

[UnclePsymon]

Thanks for the reply!
Codeium is enabled and also shows me suggestions under my cursor (i think this is nvim-cmp). action.__raw = "function() return vim.fn['codeium#Accept']() end"; and action.__raw = "vim.fn['codeium#Accept']" both give me unknown funktion errors. :codeium#CycleCompletitions and :Codeium#CycleCompletitions do not exist.

[MattSturgeon]

Looking upstream, their example is

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

So to use the <cmd> style you also need to use the call command.

Have you tried :call codeium#CycleCompletitions(1)?

---

However, if you're getting "unknown function" when doing vim.fn['codeium#Accept'] then something else is not right.

[UnclePsymon]

:call codeium#CycleCompletitions(1) gives me unknown funktion.
I just managed to use cmp to use the completitions. This is actually more convinient for me, so I'll use that. Thanks for the help :)
Unless you need me for some bug hunting because of the "unknown function"?

Glad you found a solution. I'd be surprised if there's an issue on our end, so I'm happy to close this.

Thanks for reporting back in!
