Goto and Rename not working with RLS

[chrisduerr]

• neovim version: 0.2.0
• Plugin version: master (5781243)
• Minimal vimrc
• Content of :CheckHealth: https://pastebin.com/At1UEcgF
• Content of ~/.local/share/nvim/rplugin.vim: https://pastebin.com/tJi2zV0j
• content of /tmp/LanguageClient.log: https://pastebin.com/YBsU6e0a

So I have recently reinstalled my computer and ever since I haven't been able to get much useful stuff out of RLS. I went over the install guide a few times but I see nothing I could have missed. While syntax errors work sometimes, stuff like rename or goto never do. Until now I have just ignored it thinking that it might just be buggy right now but it has been bothering me a lot.

Any idea what I could try to make this work? Chances are the mistake is somewhere on my end, but I'd be glad if someone would still be able to help me out.

Can you change log level (help) and resend the content of /tmp/LanguageClient.log please ?

[chrisduerr]

That first part is the normal setting and at the bottom it's with the debug log level. There is info and debug. Is there any other log level not mentioned in the help?

[DeltaEvo]

Oh yes i'm sorry but some parts are missing. Can you change log level before starting the language server ?

[autozimu]

The log is not complete.

Please follow steps to get a new complete log file

• cleanup /tmp/LanguageClient.log
• reopen neovim
• set LanguageClient logging level
• reproduce the issue
• resend all content of /tmp/LanguageClient.log

I would also recommend you try a simple project, like https://github.com/autozimu/LanguageClient-neovim/tree/master/rplugin/python3/tests/sample-rs to see if it works.

I have a similar Problem. Nothing works. Only the autocompletion works. But not as it should, I guess. I set LanguageClientLoggingLevel to 'DEBUG'. This is the output:

$ cat /tmp/LanguageClient.log 
21:02:27 WARNING  no handler implemented for rustDocument_diagnosticsBegin
21:02:27 WARNING  register completion manager source failed. Error: NvimError(b'Error calling function.',)
21:02:30 WARNING  no handler implemented for rustDocument_diagnosticsEnd

[DeltaEvo]

@Ronaldho80 you should try to follow @autozimu steps because there is no debug messages in your output

[Ronaldho80]

I thought, I did. I cleaned the log file. I set the debugging level with:

let g:LanguageClient_setLoggingLevel = 'DEBUG'

in init.vim. I restarted and re-did what I did to generate Error messages.

[DeltaEvo]

LanguageClient_setLoggingLevel is a function, not a variable 😄

[chrisduerr]

So this is a bit odd. I tried it again with the simple issue and it didn't work. Then I cleared the log to give it a clean run of a single failed attempt and suddenly both goto and rename work. Without me changing anything at all.

Now it suddenly also works for a project where it did nothing at all before.

However one of my actually bigger projects still refuses to work, so here is the log for that project, not the minimal demo: https://pastebin.com/X8yyk6D9

I tried both goto and rename in this example. I'm sorry that this now got so odd and convoluted, I have no idea why suddenly part of my projects work. I'd still love to make it work for all my stuff tho.

[autozimu]

It's a function call to set log level, not variable.

Ah! ;-) Thx, for the hint. Here is the log file: https://pastebin.com/2jJTzUq8

@chrisduerr the large projet that are you trying on is https://github.com/dogamak/xcbars ?

This seems to be an rls issue, but I will try to find it 😄

[chrisduerr]

Yeah exactly. I saw in the LC log that part of the other project was still in there, so here it's cleaned up: https://pastebin.com/6ZyLMJjs

Seems like it just does a whole lot of nothing to my untrained eye. Not sure if this might be an rls issue.

[Ronaldho80]

I tried the small Rust project in LanguageClient/.../sample-rs. Everything works as it should. My project is much bigger with 70000 loc. I wonder what's the problem though....

[DeltaEvo]

I think yes @Ronaldho80 rls doesn't handle well large projects for the moment 😢
