Dynamically replace sources temporarily

[hinell]

Hi. Is it possible to substitute/replace currently available sources DYNAMICALLY and then swap previous state back?

Possible use case is snippet's choices, like cmp-luasnip-choice. The latter provides sources that are polluted by other's completion.

Usually, in case of choices exact possible items are fixed. No need to complete anything else...

A possible way I can think of is to make a keybind calling complete with custom sources

    ["<C-n>"] = cmp.mapping({
      i = function()
        if cmp.visible() then
          cmp.select_next_item(select_only)
        else
          cmp.complete({
            config = {
              sources = {
                { name = 'luasnip_choice' },
              },
            },
          })
        end
      end,
    }),

Thanks. I actually came up with a conditioned solution:

["<C-Space>"] = cmp.mapping({
	i = function(fallback)
		local luasnip = require("luasnip")
		if luasnip.choice_active() then
			if not cmp.complete({
				config = {
					sources = {
						{ name = "luasnip_choice" },
						{ name = "luasnip" }
					}
				}
			}) then
				cmp.abort()
				return fallback()
			end
			return
		end
		if not cmp.complete() then
			cmp.abort()
			luasnip.unlink_current()
			return fallback()
		end
	end,

But then I fixed cmp-luasnip-choice plugin. Going to release it soon.
