vim-language-server settings didn't work #9

Closed Karmenzind closed 4 years ago

Karmenzind commented 5 years ago

Hi vim-language-server settings didn't work at all, neither completion or gotocmd.

vim-language-server version: 1.3.1 installed with npm install -g --production

...
      \ {"name": "vim", "filetypes": ["vim"], "cmdline": ["vim-language-server", '--stdio'] },
...

I think there should be some extra config like the samples(for coc.nvim) in https://github.com/iamcco/vim-language-server . But I have no idea how to put this into .ycm_extra_conf. Any suggestions?

here is the log:

}

The initializationOptions dictionary is what you can pass in { 'ls: <init options> } from the extra conf.

Does that help?

I think this is resolved. At least there’s been no activity and we believe it should work via extra conf.

Hi, THank you for maintaining this plugin. I found it to be faster than its contemporaries. The :YcmCompleter GoToDefinition commands and RefactorRename commands work for me with the vim-language-server, but not symantic completion or signature help. My config is:

in ~/.vimrc:
let g:ycm_language_server                           = [
                                                        \{
                                                        \ 'name'               : 'vim',
                                                        \ 'cmdline'            : ['vim-language-server', '--stdio'],
                                                        \ 'filetypes'          : ['vim'],
                                                        \ 'project_root_files' : [expand('%')]
                                                        \}
                                                     \]

And .ycm_extra_conf.py looks like:

def Settings(**kwargs):
    if kwargs["language"] == "vim":
        return {
            "ls": {
                "iskeyword": "@,48-57,_,192-255,-#",
                "vimruntime": "",
                "runtimepath": "",
                "diagnostic": {"enable": True},
            }
        }
    return {}

Is there a way to make semantic completion, or signature help work ?

puremourning commented 4 years ago

my experience with vim-language-server is that it works for about 5 minutes then ends up stuck in an infinite loop and I have to kill it. I actually use vim-Verdin with YCM and it works well (via the omnifunc).

I mean we could look into why vim-language-server isn't working, but usually it is because it's sending snippets which YCM doesn't support. Do you have some diagnostics, like the log files ?

Check YCM's CONTRIBUTING.md for the kind of logs we require to debug.

yeah, this looks suspect:

TypeError: 'NoneType' object is not iterable

it's returning None to the resolve completion request.

Could you try with g:ycm_server_log_level set to DEBUG ? That will allow us to see what the LS is sending to ycmd.

patashish704 commented 4 years ago

I have added the following variables in my minimal vimrc:

let g:ycm_log_level                                 = 'debug'
let g:ycm_server_log_level                     = 'debug'

The output of :YcmDebugInfo

Yes, the server is returning null for the completionItem/resolve request, which is invalid according to:

https://microsoft.github.io/language-server-protocol/specification#completionItem_resolve

You should report this to the server vendor.

patashish704 commented 4 years ago

Thanks for taking the time to look at it.

bstaletic commented 4 years ago

@puremourning Is this resolved now?

puremourning commented 4 years ago

yes.
