Potential additional command(s)

[leaty]

I'm unsure what to call this so bare with me. The reason I'm posting is if there's already a better way of doing this (and I just missed it), or if there's any interest in either adding as additional recipe, or implementing this behavior (I wouldn't mind giving it a shot).

I wrote a tiny custom command to allow using one key (<Tab>) for the following:

1. Press once to insert ghost text without menu
2. Press again to cancel (remove insert) and open the menu to allow fuzzy search

This way I have instantaneous and minimalistic tab completion akin to a terminal, but I can still use the menu/fuzzy search if I need to, all on the same key. In my case I also use the same key for select_next, and <S-Tab> for select_prev while the menu is open.

The command

local function insert_ghost(cmp)
	if cmp.is_menu_visible() then return end

	-- Remove ghosted insert and show menu
	if cmp.get_selected_item_idx() ~= nil then
		cmp.cancel()
		return cmp.show()
	end

	-- Insert ghost text
	if cmp.is_ghost_text_visible() then
		return cmp.select_next({ on_ghost_text = true, auto_insert = true })
	end
end

Relevant config

keymap = {
	['<Tab>'] = { insert_ghost, 'select_next', 'snippet_forward', 'fallback' },
	['<S-Tab>'] = { 'select_prev', 'snippet_backward', 'fallback' },
},
completion = {
	list = {
		selection = {
			preselect = false,
			auto_insert = true
		}
	},
	ghost_text = {
		enabled = true,
		show_with_menu = true,
		show_without_selection = true
	},
}
