Turn off cmp in TelescopePrompt buffer?

[brandoncc]

Hello,

Thanks for this awesome plugin. I could never get tab to navigate the menu compe and it does it out of the box with cmp. That alone is worth switching!

I apologize if this is the wrong place to ask, but is there an easy way to turn off compe suggestions while in a TelescopePrompt buffer?

Thanks

By default, when buftype is prompt, no completion will be shown.

nvim-cmp/lua/cmp/utils/check.lua

Line 5 in 46e5d16

ng = ng or vim.api.nvim_buf_get_option(0, 'buftype') == 'prompt'

@uga-rosa is correct.

@brandoncc I think nvim-cmp already disabled if the buftype is `prompt.

So I want a more detailed explanation of this problem.

Hello,

Thanks for the responses from both of you. As mentioned before, it is a TelescopePrompt buffer, not a prompt buffer. I promise the completion menu is popping up right now :-)

So, is there an easy way to turn it off?

that seems to be sourced from tabnine ( due to the percentage showing), wanted to mention cause that might be related

[hrsh7th]

It seems to telescope add buftype=prompt if the prompt_prefix has provided.

@brandoncc You can set up like this.

autocmd FileType TelescopePrompt lua require'cmp'.setup.buffer {
\   completion = { autocomplete = false }
\ }

[brandoncc]

Ah, so the completion setting is what I need to change. Thank you! I tried messing with completeopt in a similar autocmd, but it didn't help.

[brandoncc]

I'm getting this error:

If I change it to autocomplete = {} the error goes away but the completion menu still pops up. I also tried changing it to nil since the docs say it can be nil, but it changes the error to "expected table, got nil".

[hrsh7th]

Could you update nvim-cmp to the latest?

[brandoncc]

Thanks, that fixed the error above but the menu still shows up. At this point, I have added all of these:

autocmd FileType TelescopePrompt lua print('In TelP')

autocmd FileType TelescopePrompt lua require'cmp'.setup.buffer {
\   completion = { autocomplete = false }
\ }

autocmd FileType TelescopePrompt lua require'cmp_tabnine.config'.setup {
\    max_lines = 0
\    max_num_results = 0
\ }

The menu still pops up, but as @abzcoding mentioned, they only seem to be sourced from tabnine for some reason. I thought the code might not be executing, so I added the print call. The message does show up in my :messages, so I know the code is executing.

I also tried hacking around the issue like this:

autocmd FileType TelescopePrompt set ft=prompt

as well as

autocmd FileType TelescopePrompt lua require'cmp'.setup.buffer {
\   completion = { sources = {} }
\ }

Those didn't fix the issue either.

If it helps, here is my config:

" Setup global configuration. More on configuration below.
lua <<EOF
  local cmp = require('cmp')
  cmp.setup {
    snippet = {
      expand = function(args)
        -- You must install `vim-vsnip` if you use the following as-is.
        vim.fn['vsnip#anonymous'](args.body)
      end
    },

    -- You must set mapping if you want.
    mapping = {
      ['<C-p>'] = cmp.mapping.select_prev_item(),
      ['<C-n>'] = cmp.mapping.select_next_item(),
      ['<C-d>'] = cmp.mapping.scroll_docs(-4),
      ['<C-f>'] = cmp.mapping.scroll_docs(4),
      ['<C-Space>'] = cmp.mapping.complete(),
      ['<C-e>'] = cmp.mapping.close(),
      ['<CR>'] = cmp.mapping.confirm({
        behavior = cmp.ConfirmBehavior.Insert,
        select = true,
      })
    },

    -- You should specify your *installed* sources.
    sources = {
      { name = 'buffer' },
      { name = 'nvim_lsp' },
      { name = 'cmp-tabnine' },
      { name = 'path' },
      { name = 'calc' }
    },
  }
EOF

" Setup buffer configuration (nvim-lua source only enables in Lua filetype).
autocmd FileType lua lua require'cmp'.setup.buffer {
\   sources = {

\     { name = 'nvim_lua' },
\   },
\ }

autocmd FileType TelescopePrompt lua print('In TelP')

autocmd FileType TelescopePrompt lua require'cmp'.setup.buffer {

Even with the configuration pasted at the end of my last comment, I just experienced path completions in the telescope prompt.

[uga-rosa]

buftype is NOT filetype. Please see :h buftype

[brandoncc]

I'm not sure anyone thought buftype and filetype were the same?

[uga-rosa]

So, why this?

I also tried hacking around the issue like this:

autocmd FileType TelescopePrompt set ft=prompt

You have replaced filetype from TelescopePrompt to prompt...

[brandoncc]

Ha, touché! I missed the fact that buftype was ever mentioned, and we just thinking about filetype. I didn't understand why you randomly said buftype is not filetype. Your comment makes a lot more sense now 👍

I'll try that hack again with it fixed to set buftype instead of filetype.

[brandoncc]

autocmd FileType TelescopePrompt set bt=prompt

This didn't help.

[uga-rosa]

We told that cmp looks at the buftype, not filetype, and disables itself by default. And telescope have done this setting properly.
I feel like there is a problem with the source implementation...

[brandoncc]

I got completions for multiple sources when I have tried everything to turn it off. Thanks for your time, I think I'll move on at this point.

[brandoncc]

I updated today and this is fixed, thank you!

[brandoncc]

Actually, the problem still happens... I didn't have cmp-tabnine configured right so it wasn't working at all. One day I'll figure out how to fix it....

This one helped me. Thank you!

[palcalde]

This works:

cmp.setup({
	enabled = 
	  function ()
		     buftype = vim.api.nvim_buf_get_option(0, "buftype")
		     if buftype == "prompt" then return false end
          end
})

[dmartzol]

for me the following worked a bit better:

cmp.setup({
    enabled = function ()
        buftype = vim.api.nvim_buf_get_option(0, "buftype")
        if buftype == "prompt" then return false end
        return true
    end
})

[palcalde]

for me the following worked a bit better:

cmp.setup({
    enabled = function ()
        buftype = vim.api.nvim_buf_get_option(0, "buftype")
        if buftype == "prompt" then return false end
        return true
    end
})

I also found annoying that cmp kept showing when writing comments in code, I disabled it as well using treesitter.

[asmodeus812]

I also came across this issue, where in the telescope buffer we will get the cmp mappings on top of the telescope ones, and for telescope for example will get overriden by the cmp . There has been a change in the default method some 9 monts ago here - 801a9f9#diff-df823ce65cc2c7da6baceae5eeff942546e46b84c95571d897f0ba2f9f0385dd

Note that this also happens only in nvim 0.8, in 0.7 it works fine, which is weird, maybe something is broken upstream
