Accepting cmdline completion inserts excess -- when using selection = "auto_insert"

[chrisgrieser]

Make sure you have done the following

• I have updated to the latest version of blink.cmp
• I have read the README

Bug Description

1. press /
2. type something
3. select first item with <C-n>
4. accept with <C-y>
5. the accepted item has a leading -- in there

---

somewhat related, the enter keymap preset together with the default select = "preselect" is also not ideal. It's technically not buggy, but pressing enter often selects an item, even though you intend to search for what you have currently typed.

Relevant configuration

opts = {
	completion = {
		list = {
			selection = "auto_insert",
		},
	},
},

neovim version

NVIM v0.10.2

blink.cmp version: branch, tag, or commit

0.8.0

I dont know if this is related or not, but when I am writing a command in Neovim, it is automatically popping up the suggestions but it was not like this before the recent update.

How can I disable it? It should only appear on Tab like it used to.

Edit: I figured out that unknowingly I was using nvim-cmp for cmd completions, and now that I am using blink.cmp. I want some changes. For example, I want to not trigger by default and only trigger on Tab. Is that possible?

@itse4elhaam Sounds like you'll want to wait for #697 so you can disable auto_show in cmdline mode

[Saghen]

@chrisgrieser I'm unable to reproduce this, could you provide an example file and maybe a video of it happening?

[itse4elhaam]

Hey @Saghen, Can something like this work as a temporary workaround?

-- NOTE: not working right now in the current state

vim.api.nvim_create_autocmd("CmdlineEnter", {
  callback = function()
    require("blink.cmp").opts.completion.menu.auto_show = false
  end,
})

vim.api.nvim_create_autocmd("CmdlineLeave", {
  callback = function()
    require("blink.cmp").opts.completion.menu.auto_show = true
  end,
})

[Saghen]

Yes! Very hacky so it might break in the future :)

[itse4elhaam]

That did not work so I implemented this:

vim.api.nvim_create_autocmd("CmdlineEnter", {
  callback = function()
    vim.api.nvim_set_keymap('c', '<CR>', '<CR>', { noremap = true, silent = true })
  end,
})

For some context: I have remapped my enter and tab both for completion but in the command line it just execs my current command instead of going to the selection.

Just for reference:

      keymap = {
        preset = "super-tab",
        ["<CR>"] = { "accept", "fallback" },
      }

@Saghen

sure, here is the video. (edit: video is using noice.nvim. However, just checked, with noice.nvim turned off, the behavior is the same.)
