Feature: Extend cmp sources instead of overriding them.

[GordianDziwis]

I had to add additional sources directly to the init.lua from codecompanion.

  -- Setup cmp
  local has_cmp, cmp = pcall(require, "cmp")
  if has_cmp then
    cmp.register_source("codecompanion_models", require("cmp_codecompanion.models").new(config))
    cmp.register_source("codecompanion_slash_commands", require("cmp_codecompanion.slash_commands").new(config))
    cmp.register_source("codecompanion_tools", require("cmp_codecompanion.tools").new(config))
    cmp.register_source("codecompanion_variables", require("cmp_codecompanion.variables").new())
    cmp.setup.filetype("codecompanion", {
      enabled = true,
      sources = {
        { name = "codecompanion_models" },
        { name = "codecompanion_slash_commands" },
        { name = "codecompanion_tools" },
        { name = "codecompanion_variables" },
        { name = 'buffer' },
        { name = 'omni' },
        { name = 'async_path' },
      },
    })
  end

Do you know of a way to extend cmp sources? I could add an option in the config but wondered if there's a cleaner way to do this with cmp?

Maybe like this: hrsh7th/nvim-cmp#670 (comment)

I looked into cmp.get_config() and it just returns the base configuration. Doesn't return anything related to the codecompanion buffer type.

[GordianDziwis]

This gives me the current config when I am in a CodeCompagnion buffer

lua print(vim.inspect(require('cmp').get_config())) gives me the current buffer. So a solution could be to use an autocommand, like the one for too big buffer from the cmp wiki:

vim.api.nvim_create_autocmd('BufReadPre', {
	callback = function(t)
		local sources = default_cmp_sources
		if not bufIsBig(t.buf) then
			sources[#sources+1] = {name = 'treesitter', group_index = 2}
		end
	cmp.setup.buffer {
		sources = sources
	}
	end
})

This has been fixed in v11.5.0

Thanks!
