Mappings with Snippet Choice Nodes

[tris203]

Make sure you have done the following

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

Bug Description

Given a snippet with a choice node, and a supertab keymap

a snippet such as this

{
  "coc": {
    "body": "${1|fix,feat,build,chore,ci,docs,style,refactor,perf,test|}(${2:scope}):${3:title}",
    "prefix": "coc"
  }
}

will need <c-y> to accept from the choice node.

Relevant configuration

keymap = { preset = 'super-tab' },

neovim version

NVIM v0.11.0-dev-1408+gffaab09e99

blink.cmp version: branch, tag, or commit

0.8.1

Seems like this would be up to the snippet provider you're using. The default uses the built in vim.snippet but there's also LuaSnip and mini.snippets

[tris203]

I think it gets a bit more complicated than that to overwrite, as if you wanted to use <Tab> for that menu too, then blink has already set buffer local keys maps for the key

[saghen]

Ah I see, you want the completion menu to popup with the options. Putting this in the backlog for now

I am trying to understand why my bindings for select_next and select_prev do not work in these snippet choice modes, is this issue related to that?

With,

keymap = {
    preset = 'default',
    ['<C-j>'] = { 'select_next', 'fallback_to_mappings' },
    ['<C-k>'] = { 'select_prev', 'fallback_to_mappings' },
}

The snippet choices selection can be moved with C-n and C-p, but not with the bindings above.

After some more looking into this, turns out Blink has nothing to do with it and what I needed was to rebind nvim's own bindings for pum selection.

For anyone that ends up here with the same issue, this will do:

vim.keymap.set('i', '<C-j>', '<C-n>')
vim.keymap.set('i', '<C-k>', '<C-p>')

Considering you don't have any insert mode bindings for C-j and C-k.

From luasnip.txt

vim.keymap.set("i", "<C-n>", "<Plug>luasnip-next-choice", {})
vim.keymap.set("s", "<C-n>", "<Plug>luasnip-next-choice", {})
vim.keymap.set("i", "<C-p>", "<Plug>luasnip-prev-choice", {})
vim.keymap.set("s", "<C-p>", "<Plug>luasnip-prev-choice", {})

Works for me!

As for the completion menu, see luasnip-extras-select_choice. I couldn't get it to work nicely, and it breaks following choice nodes for me.
