Can't get key binding to work (almost certainly user error)

[nexxai]

I'm moving over from codeium.vim to codeium.nvim and for some reason, I can't figure out how to migrate my old manual keybinding to the new plugin.

Specifically, I have the nvim-cmp setup disabled, and I would like to be able to press CTRL+SPACE to accept the virtual text suggestion.

The old way:

...
    vim.keymap.set("i", "<C-Space>", function()
      return vim.fn["codeium#Accept"]()
    end, { expr = true, silent = true })
...

What I believe (obviously incorrectly) should work:

return {
  "Exafunction/codeium.nvim",
  dependencies = {
    "nvim-lua/plenary.nvim",
    "hrsh7th/nvim-cmp",
  },
  config = function()
    require("codeium").setup({
      enable_cmp_source = false,
      virtual_text = {
        enabled = true,
        key_bindings = {
          accept = "<C-Space>",
        },
      },
    })
  end,
}

Based on the README, this reads like it should work, but I can't seem to get it to take.

When I run :map, it doesn't even show as being a registered key binding for anything:

n  <C-Space>   *@<Lua 597: ~/.local/share/nvim/lazy/nvim-treesitter/lua/nvim-treesitter/incremental_selection.lua:15>
                 Start selecting nodes with nvim-treesitter
x  <C-Space>   *@<Lua 863: ~/.local/share/nvim/lazy/nvim-treesitter/lua/nvim-treesitter/incremental_selection.lua:58>
                 Increment selection to named node

What am I doing wrong here? If I leave the key_bindings list off, <Tab> does work as the accept key, but I would prefer not to use that if I don't have to. Defining my own key binding obviously prevents the TAB key from accepting the completion.

Hmm, this works for me and your config looks similar to mine. I think you need to use :imap (or even :imap <c-space>) to show the insert-mode keybindings though, that might help in figuring out what's wrong here. My first guess would be that some other plugin is maybe overwriting the keybinding.

If I do :imap, I see this:

If I do :imap <C-Space> it says that no mappings are configured

It doesn't work for me either... I tried Tab and Ctrl+k

I'm facing the same problem.
