Symbols in information column of omnicomplete

[chopfitzroy]

Information

VIM version

NVIM v0.2.2
Build type: RelWithDebInfo
LuaJIT 2.1.0-beta3

Operating System:

Debian Buster

What went wrong

Using a minimal init.vim with completion the following symbols are in the omnicompletion description column {^@ I am going to hazard a guess and say these are line breaks and come from LSP/tsserver.

Would it be possible to omit them, or replace them with a ... and put the whole output (with line breaks) in the buffer up the top (I forget what this is called)

Reproducing the bug

I have uploaded a screenshot of what it looks like here here.

My init.vim:

if empty(glob('~/.config/nvim/autoload/plug.vim'))
  silent !curl -fLo ~/.config/nvim/autoload/plug.vim --create-dirs
    \ https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
  autocmd VimEnter * PlugInstall --sync | source $MYVIMRC
endif

let g:ale_completion_enabled = 1
let g:ale_completion_max_suggestions = 10

call plug#begin('~/.vim/plugged')
Plug 'w0rp/ale'
call plug#end()

set completeopt=menu,menuone,preview,noselect,noinsert

Can you produce a minimal project which repeats the bug? That will make it easier to track down where the message is coming from.

[chopfitzroy]

Sure,

Using the above init.vim:

if empty(glob('~/.config/nvim/autoload/plug.vim'))
  silent !curl -fLo ~/.config/nvim/autoload/plug.vim --create-dirs
    \ https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
  autocmd VimEnter * PlugInstall --sync | source $MYVIMRC
endif

let g:ale_completion_enabled = 1
let g:ale_completion_max_suggestions = 10

call plug#begin('~/.vim/plugged')
Plug 'w0rp/ale'
call plug#end()

set completeopt=menu,menuone,preview,noselect,noinsert

And having tsserver installed, editing a .js file type: Can, it should show the error for all of the Canvas* entries.

Is this what you were asking for?

[w0rp]

Do you have a package.json file I could built a project with, to test this with? I'd like to try with something which produces the same output.

[chopfitzroy]

Hey,

I don't actually have a package.json this just happens when I work with any .js file (haven't tried .ts as I haven't used TypeScript yet) I did open the project in a fresh loopback project and I was able to replicate, I could create a repo for this, but from what I can tell you should be able to reproduce anywhere.

Before we go any further I am correct in thinking I can use tsserver for .js files to?

Cheers.

[w0rp]

Yes, you should be able to use tsserver for .js files. I use tsserver with ALE every day at work, and I haven't seen this issue yet. There may be some more configuration required for repeating this bug.

[chopfitzroy]

Okay I thought it might be my terminal (I use alacritty) but I tested it with gnome-terminal and was able to reproduce the same output. Is there anything custom that needs to be done to set up tsserver appropriately?

[w0rp]

tsserver should work pretty much straight away if you have installed TypeScript into node_modules.

[chopfitzroy]

I am using a global install of TypeScript I wonder if this is the issue, should I try a local install next to my .js files?

[w0rp]

You should just be able to install it into node_modules with npm install or yarn, and it will work without you having to change any settings.
