Integration with nvim-cmp about ultimate-autopair.nvim HOT 21 OPEN

Currently that specific feature is not possible.
I may decide to add the feature in the future.

from ultimate-autopair.nvim.

If anyone wants this feature before I implement it:

local cmp=require('cmp')
local Kind=cmp.lsp.CompletionItemKind
cmp.event:on(
  'confirm_done',
  function (evt)
    if vim.tbl_contains({Kind.Function,Kind.Method},evt.entry:get_completion_item().kind) then
      vim.api.nvim_feedkeys('()'..vim.api.nvim_replace_termcodes('<Left>',true,true,true),'n',false)
    end
  end)

from ultimate-autopair.nvim.

I modified @altermo's temporary solution to exclude lua_ls and rust_analyzer, since they already create pairs themselves.

The pcall is to catch any null pointer exception when doing event.entry.source.source.client.config.name.

local cmp = require('cmp')
local ind = cmp.lsp.CompletionItemKind

local function ls_name_from_event(event)
  return event.entry.source.source.client.config.name
end

-- Add parenthesis on completion confirmation
cmp.event:on('confirm_done', function(event)
  local ok, ls_name = pcall(ls_name_from_event, event)
  if ok and vim.tbl_contains({ 'rust_analyzer', 'lua_ls' }, ls_name) then
    return
  end

  local completion_kind = event.entry:get_completion_item().kind
  if vim.tbl_contains({ ind.Function, ind.Method }, completion_kind) then
    local left = vim.api.nvim_replace_termcodes('<Left>', true, true, true)
    vim.api.nvim_feedkeys('()' .. left, 'n', false)
  end
end)

from ultimate-autopair.nvim.

Looking forward to this useful feature!

It will take some time until I come up with a good design, so in the meantime, I created an experimental version.

To use it:

require'ultimate-autopair'.init({
  require'ultimate-autopair'.extend_default{
      --Normal config goes here
  },
  {profile=require'ultimate-autopair.experimental.cmpair'.init},
})

from ultimate-autopair.nvim.

Yes, use require'ultimate-autopair.maps.cr'.cmpnewline() like so:

cmp.mapping(function()
    if cmp.get_active_entry() then
        cmp.confirm()
    else
        require'ultimate-autopair.maps.cr'.cmpnewline()
    end
end)

Hello, I'm still looking forward to this useful feature

from ultimate-autopair.nvim.

Yes sir. This is the last reason I still use nvim-autopairs.

Hi again, thanks for the help! I might have missed something, but I couldn't make it work with your code snippet. In case my request didn't go through: I was asking whether it is possible to add a pair of parenthesis to a cmp completion item which is a function. This was accomplishable by nvim-autopairs as shown in the link I provided above. I am not good at reading lua code or nvim apis, but I didn't see the part related to check whether the completion item is a function and adding the parenthesis etc. in the cmpnewline function. I would appreciate your help again!

This is a gif showing the effect that I want to achieve:

This feature is indeed very useful, looking forward to it 😄

from ultimate-autopair.nvim.

Sorry, currently don't find the resources, but doesn't nvim-cmp support inserting parenthesis after the completion by itself?

from ultimate-autopair.nvim.

If it does then I can't figure out how to. I just switched from LazyVim to Kickstart and I tried getting the function completion to work like lazy had.and lazy doesn't use the cmp:on_event trick but I have no idea how it gets function completion to work otherwise.

from ultimate-autopair.nvim.

Okay, it seems like this is a feature of the LSP completion where some servers provide this feature by using snippets. Sorry.

from ultimate-autopair.nvim.

Very wholesome, very useful feature. In the meantime try and configure the LSP you use to send snippets for completion. This varies per LSP. That's how I got around it so far. Clangd, jdtls, luals, and pyright all support it. So thats all I need for now.

from ultimate-autopair.nvim.

I was actually thinking about exactly such a solution. Probably just need to make it a liiiittle more advanced, so it does not interfere with server which do actually send additional snippets to add them too.

from ultimate-autopair.nvim.

@altermo This works great, but I found that it doesn't work on JavaScript/TypeScript arrow functions:

const foo = (bar, baz) => bar + baz;

I realize that this is trickier, but is this something that would be possible to support?

from ultimate-autopair.nvim.

How would it work exactly?
What would the trigger be for the auto parentheses?

from ultimate-autopair.nvim.

As I was typing out a response to this I realize that it's probably too difficult :)

from ultimate-autopair.nvim.

Hi @mawkler, thanks a lot , I have used your config with pylsp very well

from ultimate-autopair.nvim.

Is there an official response why something like this isn't implemented in cmp-nvim directly? Or at least a snippet like this for those that don't want to rely on per-autopair plugin implementation. I don't think that any autopair plugin actually needs to insert that parenthesis pair in a special way. Unless it does?

P.S. I started searching here after I stumbled upon hrsh7th/nvim-cmp#1672. I also had to include tinymist in the list.
