I've succeeded in configuring a vim-c++ environment based on the plugin YCM and the plugin ale.

I use YCM to do the auto-completion and ALE to hint me errors and warnings.

I added the config as below to update the status line:

set statusline+=%#warningmsg#
function! LinterStatus() abort
    let l:counts = ale#statusline#Count(bufnr(''))
    let l:fst = ale#statusline#FirstProblem(bufnr(''), 'error')
    let l:all_errors = l:counts.error + l:counts.style_error
    let l:all_non_errors = l:counts.total - l:all_errors
    return l:counts.total == 0 ? 'OK' : printf(
    \   '%dW %dE(%d)',
    \   all_non_errors,
    \   all_errors,
    \   fst.lnum
    \)
endfunction
set statusline+=%{LinterStatus()}
set statusline+=%*

It worked as expected.

For example, the c++ code as below will show 0W 1E(3) at the status line.

int main()
{
    xxxx
}

Now I'm trying to configure a vim-golang environment with the plugin YCM and the plugin ALE.

I've built the YCM with the command ./install.py --go-completer. For ALE, I used the same config as above and I add one line to configure golang:

let g:ale_linters = {'go': ['gopls', 'golangci-lint', 'gofmt']}.

However, the status line always show me OK, meaning that there is no error, no matter how I create an error.

enter image description here

As you can see, there does exist an error but the status line shows me an OK.

  • What put the sign there, ale or ycm? – D. Ben Knoble Mar 23 at 11:57
  • @D.BenKnoble it should be ycm. – Yves Mar 23 at 14:12
  • Ok. So what is :ALEInfo saying? – D. Ben Knoble Mar 23 at 14:51
  • @D.BenKnoble I put the output in the question. – Yves Mar 24 at 1:18
  • @D.BenKnoble In fact, I tried to use ALE without YCM, but it doesn't seem that ALE can do autocompletion, which means that I have to type <C-x><X-o> manually... So I mixed them up or what? – Yves Mar 24 at 1:56
