Omnisharp + YCM autocompletion errors

[Stewmath]

I'm getting errors whenever I type a letter after the autocompleter comes up.

Error detected while processing function <SNR>50_OnCompleteDone:
line    1:
  File "~/.vim/bundle/YouCompleteMe/autoload/../python/ycm/youcompleteme.py", line 304, in OnCompleteDone
Press ENTER or type command to continue
Error detected while processing function <SNR>50_OnCompleteDone:
line    1:
    action(self)

Removing the offending lines in this function actually seems to fix the issue, and the autocompleter works, though I've got no idea what functionality I'm disabling. I'm not sure how to debug further. This is the function I disabled.

def OnCompleteDone( self ):
    complete_done_actions = self.GetCompleteDoneHooks()
    for action in complete_done_actions:
      action(self)

A bit more information. My log after autocomplete goes crazy:

@Drenn1 in the first post, are you sure you included the whole message? If you did :messages was there more of a trace back? It isn't obvious what is up here from the available context.

It would help to get a small reproducible test case.

The function that you are 'missing' is the ability in c-sharp files to automatically insert import declarations when selecting completions. See this PR for details.

[mispencer]

@Drenn1 Can you check if https://github.com/Valloric/YouCompleteMe/pull/1916 fixes these errors?

[Stewmath]

I thought the error messages were just repeating themselves, so I only included a portion, but here's the full thing. Might be more useful than I realized.

mispencer, that does fix it. Thanks :)

[Stewmath]

I've got a test case if you still want to look at it. https://gist.github.com/Drenn1/d5eb9765d8b0013cd189

I have, of course, pathogen installed, with omnisharp-vim and YouCompleteMe in the bundle folder.

[puremourning]

So you're not using YCM's omnisharp completer, but just the omnifunc integration?

@mispencer that sounds like we shouldn't be executing these completion done commands when c-sharp isn't a semantic-enabled language ?

[Stewmath]

Autocompletion is working with that pull request, if that's what you're asking. Though I might not be understanding the question correctly.

[puremourning]

I was asking if you were using YCM's own semantic engine for C-sharp completions. That is: did you pass --omnisharp-completer to install.py when you built YCM ?

FWIW YCM's own completers typically offer a much better experience that any alternate plugin via the omnifunc.

[Stewmath]

I see, so they have their own versions of that functionality? I did not pass that before, I'd previously built it for c++. Though I apologize since that was clearly in the readme. It seems like that fixes the issue as well, along with commenting out omnifunc=OmniSharp#complete.

[puremourning]

No need to apologise :) I hope your YCM experience is improved by the c-sharp completer. Such as the auto-import of namespaces :) :grin:
