coq_nvim completion hack

[TheLazyCat00]

Today I wanted to try out coq_nvim instead of blink. But codecompanion only configures autocomplete for nvim_cmp and blink.cmp, so I had to implement my own hack.
This hack should work for every completion plugin, since it uses neovim's <C-_>.

This is the solution I came up with:

vim.api.nvim_create_autocmd("FileType", {
	pattern = "codecompanion",
	callback = function (args)
		vim.keymap.set("i", "/", function()
			vim.cmd("normal! i/")
			vim.cmd("stopinsert")
			vim.api.nvim_input("la<C-_>")
		end, { noremap = true, buffer = true })

		vim.keymap.set("i", "@", function()
			vim.cmd("normal! i@")
			vim.cmd("stopinsert")
			vim.api.nvim_input("la<C-_>")
		end, { noremap = true, buffer = true })
	end
})
