How to prefer luasnip over lsp ?

[lotusirous]

I would like to have the luasnip selected before lsp recommendation. Do we have any method to achieve this behavior ?

Here is the following config

local cmp = require("cmp")
local cmp_action = require("lsp-zero.cmp").action()
local cmp_format = require("lsp-zero").cmp_format()
local cmp_select_opts = { behavior = cmp.SelectBehavior.Select }

cmp.setup({
	formatting = cmp_format,
	sources = {
		{ name = "path" },
		{ name = "nvim_lsp" },
		{ name = "buffer", keyword_length = 3 },
		{ name = "luasnip", keyword_length = 2 },
		{ name = "nvim_lsp_signature_help" },
	},
	window = {
		completion = cmp.config.window.bordered(),
		documentation = cmp.config.window.bordered(),
	},
	snippet = {
		expand = function(args)
			require('luasnip').lsp_expand(args.body)
		end,
	},
	mapping = {
		["<C-k>"] = cmp.mapping.confirm({ select = true }),
		["<C-e>"] = cmp.mapping.abort(),
		["<C-u>"] = cmp.mapping.scroll_docs(-4),
		["<C-d>"] = cmp.mapping.scroll_docs(4),
		["<C-f>"] = cmp_action.luasnip_jump_forward(),
		["<C-l>"] = function()
			local ls = require("luasnip")
			if ls.choice_active() then
				ls.change_choice(1)
			end
		end,
		["<C-b>"] = cmp_action.luasnip_jump_backward(),
		["<Up>"] = cmp.mapping.select_prev_item(cmp_select_opts),
		["<Down>"] = cmp.mapping.select_next_item(cmp_select_opts),
		["<C-p>"] = cmp.mapping(function()
			if cmp.visible() then
				cmp.select_prev_item(cmp_select_opts)
			else
				cmp.complete()
			end
		end),
		["<CR>"] = function(fallback)
			if cmp.visible() then
				cmp.mapping.confirm({ select = true })(fallback)
			else
				return fallback()
			end
		end,
	},
})

Where the luasnip is lazy loading from vscode

require("luasnip.loaders.from_vscode").lazy_load()

The easiest way I can think of is moving the luasnip source above nvim_lsp. That will change the "priority" of the completion items.

sources = {
  { name = "path" },
  { name = "luasnip"},
  { name = "nvim_lsp" },
  { name = "buffer", keyword_length = 3 },
  { name = "nvim_lsp_signature_help" },
},

My personal preference is to have different keyword_length. So luasnip suggestions will appear on 2 keystrokes, and the lsp appear after 3 keystrokes. But I still keep the lsp with higher priority.

sources = {
  { name = "path" },
  { name = "nvim_lsp", keyword_length = 3 },
  { name = "buffer", keyword_length = 3 },
  { name = "luasnip", keyword_length = 2 },
  { name = "nvim_lsp_signature_help" },
},

Oops, I didn't know the order mattered. Thanks for your help!
