source OmniSharp timeout after 5000ms

[rodrigomocca]

Hi, I've copied/pasted the .vimrc file from another pc and I can't get Omnisharp working. In the other pc is working as expected, but in this is giving me a timeout.

I'm installing like this: Plug 'OmniSharp/omnisharp-vim'

And I have this mappings: nnoremap u :OmniSharpFindUsages nnoremap gd :OmniSharpGotoDefinition nmap oi :OmniSharpFindImplementations nnoremap pd:OmniSharpPreviewDefinition nnoremap run :cd %:p:h:!dotnet run inoremap { {} inoremap { {}O inoremap {{ { inoremap {} {}

When opening a .cs file, after a few seconds, I'm getting the timeout error:

What I'm doing wrong?

Thanks for your help.

I don't think that error is coming from OmniSharp-vim - can you please share your full .vimrc?

I appreciate your help.

Thanks - do you mind editing that and wrapping the .vimrc in ``` regions? Some of the vimscript is being lost in the markdown translation.

[rodrigomocca]

I've updated the message, please let me know if you need anything else

[nickspoons]

Sorry, I got called away - yes that's much easier to read.

Is it possible that CoC is using its coc-omnisharp integration, and it's that that is giving the error?

[rodrigomocca]

I have no idea. The same .vimrc is working on another pc without problems, but maybe I've done something without knowing. How can I disable coc-omnisharp?

[nickspoons]

I don't know, I don't use Coc. But I can see someone getting the same error here: https://github.com/coc-extensions/coc-omnisharp/issues/5#issuecomment-525761961

[nickspoons]

Does CoC have its own configuration file, outside the .vimrc?

[rodrigomocca]

I don't have any additional coc file. I've tried to remove coc and now the timeout dissappeared, but nothing of omnisharp is working. The OmnisharStatus says everything is running but I can't see anything. In the PC I have this working, once I open a .cs file, I have colors in code, and I have suggestions while I'm typing. Edit: If I execute :OmniSharpGotoDefinition it's also not working

[nickspoons]

Can you post the log? :OmniSharpOpenLog

Reading the log, it's mandatory to have a sln file?

Edit: I don't know why the issue was closed, I didn't mean to.

[nickspoons]

Ah this is neovim on Windows. This is the issue described in the README, and in #499 - it's a neovim bug (which has been fixed, but isn't yet part of a main neovim release). The solution is to either use Vim instead of neovim, or use neovim-nightly.

[rodrigomocca]

Oh, but the other PC is also with Windows and it's working great. Well, I'll move to vim and let you know. Thanks for your help.

[nickspoons]

Can you check the version of neovim running on the other PC? Could it be a nightly build?

[rodrigomocca]

Wait, you're right. NVIM v0.5.0-610-g326b87f3b

[nickspoons]

Yeah that's a nightly build

[rodrigomocca]

Great, I'll install this version on this PC too.

Thanks for all your help.

[nickspoons]

No worries
