How to use cmdline source in vim filetype

[slawek-survicate]

I tried using cmdline in regular vim buffer but it doesnt work as expected obviously. Complations show up at the beginning of the buffer and such. I know the source is not intended to be used in regular buffers but i use https://github.com/koenverburg/cmd-palette.nvim extension which is basically a floating command-window.

Plus it worked perfectly in cmp.nvim (my cmp.nvim config for vim ft):

cmp.setup.filetype('vim', {
  sources = cmp.config.sources({
    { name = 'luasnip', priority = 1 },
    {
      name = 'cmdline',
      option = { ignore_cmds = { 'Man', '!' } },
      priority = 2,
    },
    { name = 'path', group_index = 2 },
    { name = 'buffer', group_index = 2 },
  })
})

Is there something we can do about it?
