Help: include signature info in completion menu?

[valentin-krasontovitsch]

Problems summary

I would like to see function signatures in completion menu when using nvim-lsp source with ddc, and cannot figure out how to achieve this.

I'm sorry for bothering you, but after many hours of trying many things I cannot figure this out. Looking at omnifunc completion menu (triggered by C-x C-o), there are function signatures, but with ddc (with native interface) these are not there. you only have name, type, and mark.

I'm aware of the popup preview (matsui54/denops-popup-preview.vim), but i would like to see all signatures immediately. I have tried the pum UI, but did not find options for adding more columns (or at least could not figure it out).

I have to say that I'm a noob when it comes to the inner working of vim or nvim, and plugins, and lsp in vim, ... so I'm sorry if this is a silly question. it seems like it should be possible though, based on recording from @amikai in screenshot issue - but even studying his vim config, I could not see the trick : (

Expected

lspconfig.gopls.setup{
	capabilities = capabilities,

    ['lsp'] = {
      mark = '[LSP]',
      forceCompletionPattern = {[[\.\w*]]}
    }
  })

How to reproduce the problem from neovim/Vim startup (Required!)

1. open for instance following go file with nvim -u [path_to_minimal_config]:

package main

import (
	"fmt"
)

func main() {
}

2. Start typing in the main func: fmt.Pr
3. Wait for completions menu

Screenshot (if possible)

1. with ddc

2. with omnifunc from nvim-lsp

Sorry. It is not ddc.vim's issue. It should be ddc-source-lsp issue.
