Languageclient-neovim: Error symbol of linter does not disappear when writing code using neosnippet

[ikneg]

• Did you upgrade to latest plugin version? yes
• Did you upgrade to/compile latest binary? Run shell command yes
  bin/languageclient --version to get its version number.
• (Neovim users only) Did you check output of :checkhealth LanguageClient? all OK
• Did you check [troubleshooting]? yes

Describe the bug

Error symbol of linter does not disappear when writing code using neosnippet. After reopen the file, the symbol disappears.

And, when I write the same code without neosnippet, the error symbol disappears soon.

Environment

• neovim/vim version (nvim --version or vim --version):

  NVIM v0.4.3
  Build type: RelWithDebInfo
  LuaJIT 2.0.5

• This plugin version (git rev-parse --short HEAD): 51fa22f
• This plugin's binary version (bin/languageclient --version): languageclient 0.1.156
• Minimal vimrc content (A minimal vimrc is the smallest vimrc that could
  reproduce the issue. Refer to an example here):

  call plug#begin('~/.local/share/nvim/plugged')

  Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
  Plug 'Shougo/neosnippet.vim'
  let g:deoplete#enable_at_startup = 1
  Plug 'Shougo/neosnippet-snippets'
  Plug 'autozimu/LanguageClient-neovim', {
                          \ 'branch': 'next',
                          \ 'do': 'bash install.sh',
                          \ }

  call plug#end()

  augroup filetype_rust
      autocmd!
      autocmd BufReadPost *.rs setlocal filetype=rust
  augroup END

  " Always draw sign column. Prevent buffer moving when adding/deleting sign.
   set signcolumn=yes

  let g:LanguageClient_serverCommands = {
      \ 'rust': ['rustup', 'run', 'stable', 'rls'],
      \ }

  imap <space>i     <Plug>(neosnippet_expand_or_jump)
  smap <space>i     <Plug>(neosnippet_expand_or_jump)
  xmap <space>i     <Plug>(neosnippet_expand_target)

  imap <expr><TAB>
                          \ pumvisible() ? "\<C-n>" :
                          \ neosnippet#expandable_or_jumpable() ?
                          \    "\<Plug>(neosnippet_expand_or_jump)" : "\<TAB>"
  smap <expr><TAB> neosnippet#expandable_or_jumpable() ?
                          \ "\<Plug>(neosnippet_expand_or_jump)" : "\<TAB>"

To Reproduce

Steps to reproduce the behavior:

1. carge new sample && cd sample
2. Start vim, nvim src/main.rs
3. type if , and select iflse [ns] and space + i for expand target.
4. (Error symbols appear on each line of expanded code)
5. fix the placeholders.
6. Error symbol does not disappear
7. Reopen main.rs
8. Error symbol disappears

Current behavior

Error symbol does not disappear

Expected behavior

Error symbol disappears

I can reproduce this for Rust and for C.

I have a very similar issue so I thought I'd mention it here, but I can create a separate issue if needed.

My small vimrc have language client as the only plugin so no completion engine or snippets.

Very often the linter errors in the sign column doesn't disappear. I have linked the highlight group ALEError to the Error group and the highlighting of the errors does not disappear either. But I'm guessing the sign and highlighting issues have the same root cause.

I am using vim 8.2 patch 1-148. Here is my vimrc

if &compatible
    set nocompatible
endif

syntax on
filetype plugin indent on

" Force python 3
if has('python3')
endif

packadd minpac
if exists('*minpac#init')
    call minpac#init()
    call minpac#add('t-takata/minpac', {'type': 'opt'})

    " Language client
    call minpac#add('autozimu/LanguageClient-neovim', {'do': '!bash ./install.sh'})

    " Plugin commands
    command! PackUpdate call minpac#update()
    command! PackClean call minpac#clean()
    command! PackStatus call minpac#status()
endif

I can reproduce with typescript-language-server, and I remember it happening with Rust and JS Flow as well, only way to be sure errors are gone is to move cursor over line and make sure nothing shows up in status bar.

[jeffvandyke]

I started from scratch, with only LanguageClient-neovim and vim-polyglot enabled. I used 'typescript-language-server', '--stdio' as my typescript server command, and things definitely work fine. I then added these two lines:

Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
let g:deoplete#enable_at_startup = 1

And after the PlugInstall and re-opening a typescript file, even a little bit of editing causes the error sign to stick around, though errors are absent after being fixed in the file.

Here's my minimal init.vim file after installing vim-plug and npm i -g typescript-language-server:

let plugPath = "~/.local/share/nvim/plugged"

call plug#begin(plugPath)

Plug 'autozimu/LanguageClient-neovim', {
    \ 'branch': 'next',
    \ 'do': 'bash install.sh',
    \ }

let g:LanguageClient_serverCommands = {
    \ 'javascript': ['typescript-language-server', '--tsserver-log-file', '~/tsserver-log.txt', '--stdio'],
    \ 'javascript.jsx': ['typescript-language-server', '--tsserver-log-file', '~/tsserver-log.txt', '--stdio'],
    \ 'javascriptreact': ['typescript-language-server', '--tsserver-log-file', '~/tsserver-log.txt', '--stdio'],
    \ 'typescript': ['typescript-language-server', '--tsserver-log-file', '~/tsserver-log.txt', '--stdio'],
    \ 'typescript.tsx': ['typescript-language-server', '--tsserver-log-file', '~/tsserver-log.txt', '--stdio'],
    \ 'typescriptreact': ['typescript-language-server', '--tsserver-log-file', '~/tsserver-log.txt', '--stdio'],
    \ }

" Adding these two lines breaks things
" Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
" let g:deoplete#enable_at_startup = 1

Plug 'sheerun/vim-polyglot'

call plug#end()

Hi, I see a very similar behavior with both CCLS and Python language server, even without neosnippet. It feels like every error mark in the sign column has a non-zero probability of not disappearing after fixing it.
Turning vim signcolumn on/off doesn't help.
Reopening the file does help.

Could you provide some more info @grwlf , I'm pretty positive this shouldn't be an issue no more, but it shouldn't have been an issue on the date you posted either I think.
