How to disable nvim-cmp or disable all cmp-sources for certain files?

[doronbehar]

I have a long bash script with an enormous amount of variables that I think make my nvim-cmp stuck when I try to edit it. How do I disable it? I'm looking for something like treesitter's feature:

BTW I did encounter the enable = function() ... end option to cmp.setup, but the problem is that it seems that I either enable completely, or disable completely nvim-cmp... The behavior I'm looking for is per-buffer and per cmp-source: to be able to control which cmp source is enabled for each buffer. I did find out that the problematic cmp source is cmp-treesitter.

It can be managed from the source side by defining the source:is_available() method.

nvim-cmp/doc/cmp.txt

Lines 748 to 752 in e28fb7a

	---Return whether this source is available in the current context or not (optional).
	---@return boolean
	function source:is_available()
	return true
	end

In other words, this issue should be put up in cmp-treesitter, not here.

You can fully control nvim-cmp configuration based on autocmd as below.

vim.api.nvim_create_autocmd('FileType', {
  callback = function()
    require('cmp').setup.buffer {
      ...
    }
  end,
})

Thanks for the idea @hrsh7th :) For the sake of others I added a wiki subsection at:

This seems to work for me too, for completely disabling nvim-cmp for a certain filetype:

require("cmp").setup.filetype("txt", {
  enabled = false,
})
