blink.cmp prevents builtin completion from working

[midchildan]

Make sure you have done the following

• Updated to the latest version of blink.cmp
• Searched for existing issues and documentation (try <C-k> on https://cmp.saghen.dev)

Bug Description

There are 2 problems that break Neovim's builtin completion when using blink.cmp.

First, the builtin completion popup gets shown under the blink.cmp popup, preventing me from seeing the completion candidates. Below is a screenshot of when I tried to use line completion (ctrl-x ctrl-l) with blink.cmp enabled.

This can be worked around by pressing ctrl-e before attempting to trigger builtin completion. But this leads us to the second problem, which is that ctrl-y doesn't work for builtin completion.

Relevant configuration

neovim version

NVIM v0.11.0 Build type: Release LuaJIT 2.1.1741730670 Run "nvim -V1 -v" for more info

blink.cmp version

v1.1.1

You can set completion.menu.auto_show to a function that returns false when built-in completions are open. You can set keymap = { ['<C-y>'] = { 'select_and_accept', 'fallback' } } to fallback to the built-in behavior when the menu isn't open

[Saghen]

Ah, that makes sense. If there's an autocmd that fires, you could try calling require('blink.cmp').hide()

[midchildan]

Using the TextChangedP autocmd seems to be effective.

vim.api.nvim_create_autocmd('TextChangedP', { callback = require('blink.cmp').hide })

Would you be open to making this and the <C-y> changes the default? I find the builtin completion still useful and it'd be great if it can coexist with blink.cmp out of the box.

[Saghen]

Adding a recipe for this would be great but it shouldn't be the default behavior as most people don't use the built-in completions with blink.cmp. That's why by default, we don't fallback <C-y> as this would show the built-in menu

[midchildan]

Like adding a new config option? That would be convenient.

I'm not sure what you mean by <C-y> showing the built-in menu though. So far, I'm not seeing any interference between blink.cmp and builtin functionality as a result of this change. If either the blink.cmp or builtin completion is active, it accepts the selected completion candidate. Otherwise, it inserts the character above the cursor.

[Saghen]

Sorry, I meant <C-n> which shows the built-in completion if you have 'fallback'. And by recipe, I meant adding it to this page: https://cmp.saghen.dev/recipes
