```lua
{
  -- Disable for some filetypes
  enabled = function()
    return not vim.tbl_contains({ "lua", "markdown" }, vim.bo.filetype)
      and vim.bo.buftype ~= "prompt"
      and vim.b.completion ~= false
  end,

  completion = {
    -- 'prefix' will fuzzy match on the text before the cursor
    -- 'full' will fuzzy match on the text before *and* after the cursor
    -- example: 'foo_|_bar' will match 'foo_' for 'prefix' and 'foo__bar' for 'full'
    keyword = { range = 'full' },

    -- Disable auto brackets
    -- NOTE: some LSPs may add auto brackets themselves anyway
    accept = { auto_brackets = { enabled = false }, },

    -- Don't select by default, auto insert on selection    
    list = { selection = { preselect = false, auto_insert = true } },
    -- or set either per mode via a function
    list = { selection = { preselect = function(ctx) return ctx.mode ~= 'cmdline' end } },

    menu = {
      -- Don't automatically show the completion menu

  },

  sources = {
