How to configure blink to behave like (neo)vim default completion?

[brucejxz]

I'm trying to configure blink to behave like the default buffer completion in (neo)vim. I had thought that the following (stripped down) config would do the trick:

require('lazy').setup({
  {
    'saghen/blink.cmp',
    event = 'VimEnter',
    version = '1.*',
    build = 'cargo build --release',
    opts = {
      keymap = {
        preset = 'default',
        ['<C-n>'] = { 'select_next', 'show', 'fallback' },
      },
      completion = {
        list = { selection = { preselect = true, auto_insert = true } },
        menu = { auto_show = false },
      },
      fuzzy = { implementation = 'rust' },
    },
  },
})

But you can see the difference in the below video. At the top is neovim with blink.cmp configured as above and at the bottom is neovim with a blank init.lua:

At the top, when I press <Ctrl-n> the first time and the menu pops up, the text for something is not inserted, but on subsequent presses of <Ctrl-n>, the text is inserted. This differs to the default completion example at the bottom where someone is inserted on the first press of <Ctrl-n>.

In summary, what I want is:

• Completion not shown unless manually triggered using <Ctrl-n>
• Hit <Ctrl-n> once:
  • Open the completion menu
  • Select the first item
  • Insert the first item
• Hit <Ctrl-n> again:
  • Keep cycling through the options, inserting them

Have you ever figured this out? blink is driving me mad in that I can't seem to turn off "auto_show" until a shortcut is pressed. I can only fully disable (no completion at atll) or fully enable (******* annoying menu pops up all the time).

EDIT: Okay, forget it, it seems that for you it somewhat works to only pop up the menu on keypress.

Hey @cug. I haven't been able to figure it out, no. My issue is with auto_insert seemingly not working on the first keypress. For your issue though, setting auto_show = false should ensure that the popup menu doesn't show until the keymap for show is pressed, which I think is what you want.

I have figured out a configuration that works for me:

return {
	"saghen/blink.cmp",

	-- Don't show completion menu until key is pressed
	opts = {
		completion = {
			trigger = {
				show_on_keyword = false,
				show_on_trigger_character = false,
			},
			menu = {
				auto_show = false,
			},
		},
	},
}

I haven't even set a shortcut, it seems there is a default for CTRL-Space somewhere but I haven't checked since I was busy with other things.

It's actually a blink default. That's why Ctrl-space works. For me, this is perfect.
