Description

When completing with cmp with the tsserver LSP it sometimes fails to register ( or ) strokes if you type them fast enough. This is fairly consistent for me and a real annoyance.

Steps to reproduce

• Use the config file provided.
• Write the beginning of an builtin, like RegExp.
• Complete the builtin in the menu.
• Exist and complete by rapidly pressing ( and then ).

I've only been able to reproduce this on the tsserver LSP. Completion via the buffer or sumneko_lua works fine.

Adding a screenrecording for clearity. The sound gives an indication of the speed of the keypresses. https://user-images.githubusercontent.com/2284724/184642619-e6989b57-8295-4a94-911f-18ddb333e66e.mp4

Expected behavior

All characters should be inputted.

Actual behavior

Inconsistent input of characters depending of speed of input.

Your screencast is clear to understand to me but couldn't reproduce it.

@hrsh7th Are you selecting the first completion item in your screencast? I need to have a completion item selected to be able to reproduce this.

i think i had the same issue quite a while ago and i didn't want to confirm completions all the time so i added this, seems to be working ok:

    ['()'] = cmp.mapping(function()
      cmp.mapping.complete()
      vim.api.nvim_put({ '()' }, 'c', false, true)
    end, { 'i' }),

Thank you for sharing. I'll try that first thing once I've won the battle over a certain stomach bug. Looks really promising though 🙏

[sQVe]

@gimerstedt This does indeed seem to fix the issue! 🙏🏼

I've now mapped the following function to ():

  local parentheses = function(fallback)
    if cmp.visible() then
      cmp.complete()
      vim.api.nvim_put({ '()' }, 'c', false, true)
    else
      fallback()
    end
  end

I still can't reproduce this...

I'll just note that I'm experiencing the same issue, but can't seem to figure out where it's originating from. I've tried:

• multiple neovim versions (v0.7.0, v0.7.2, v0.8.)
• multiple typescript-language-server versions (v0.4.0, v1.1.2, v2.1.0)
• multiple nvim-cmp versions (I just checked out a few commits from 2022)
• multiple nvim-lspconfig versions
• multiple terminal emulators (GNOME terminal, Terminator)

And now I'm not sure where to go from here. @hrsh7th If you have any advice on where to look, I'd be happy to try and continue debugging this issue.

In the meantime, @gimerstedt 's fix works for me too.

vim.api.nvim_put({ '()' }, 'c', false, true)

This works but the cursor ends up after () which is a bit annoying, would be interesting to have the cursor inside brackets.
