Plugin crashes because treesitter is not available.

[bagohart]

Hi,
I just tried this plugin because nvim-cmp breaks manual ^X^L completion for me.
I don't use treesitter.
I configured it like this:

                    ['<C-x><C-l>'] = cmp.mapping.complete({ -- manual ^X^L is broken, so use this instead...
                        config = {
                            sources = {
                                { name = 'buffer-lines' },
                                option = {
                                    words = true,
                                    comments = true,
                                    leading_whitespace = false,
                                },
                            },
                        },
                    }),

When I press ^X^L I get:

E5108: Error executing lua: .../nvim-cmp-buffer-lines/lua/cmp-buffer-lines/complete.lua:19: module 'nvim-treesitter.ts_utils' not found:

My suspicion is that the condition in complete.lua is wrong:

local function rmcomments(nmbr, line)
	-- Use tree-sitter if is installed
	if not (vim.fn.exists(":TSUpdate") >= 2) then
		local ts_utils = require "nvim-treesitter.ts_utils"

Can you run the following Vim command and tell me what the output is?

echo exists(":TSUpdate")

[bagohart]

Yeah, it's 0.

My suspicion is that the condition in complete.lua is wrong:

  -- Use tree-sitter if is installed
  if not (vim.fn.exists(":TSUpdate") >= 2) then
  	local ts_utils = require "nvim-treesitter.ts_utils"

I think you're right, I shouldn't have the not there. Please check if the latest commit fixes your issue.

Great, that works. Thanks!
