Workspace symbol not populated when trying to use this Language server from 'neovim'

[PrajitP]

Note

I don't think this is bug. It is mostly me trying to figure out how to configure this language server to work with 'vim' or 'neovim'.

Given that all the code exist and is also being in used, and is tested with vscode. I am trying to understand how vscode language client works, specially when are method related to workspace get trigger and what is the content of those methods.

Once I figure this out I will configure my neovim language client to send that command and also document it for others.

TODO

• [ ] Configure this to work with Neovim and add the documentation for it.

How to reproduce

• My 'neovim rc' settings

  
  call plug#begin('~/.config/nvim/plugged')
  Plug 'autozimu/LanguageClient-neovim', {
       \ 'branch': 'next',
       \ 'do': 'bash install.sh',
       \ }
  call plug#end()

let g:LanguageClient_serverCommands = { \ 'perl': ['perl', '-MPerl::LanguageServer', '-e', 'Perl::LanguageServer::ru n', '--', '--debug', '--version', '2.1.0'], \ } let g:LanguageClient_loggingFile = expand('~/LanguageClient.log') let g:LanguageClient_serverStderr = expand('~/LanguageClientStderr.log') let g:LanguageClient_loggingLevel='DEBUG'

* Running the server on Perl code
```perl
my $string = "This is a test";
print $string, "\n";

• Vim command to trigger definition search, when cursor is on $string on 2nd line.

  :call LanguageClient#textDocument_definition()

  result

  Not found!

Issue

After debugging found that the, symbols attribute for $workspace(Perl::LanguageServer::Workspace) are not populated. As a result of it, 2 of functionality definitionProvider and referencesProvider which depends on 'workspace symbols' don't work. Looking through code I found that in module Perl::LanguageServer there is a method

sub parsews {
    ...
}

which populates the symbols for workspace, but looks like it not called from anywhere in the code.

Module Perl::LanguageServer::Methods::workspace also has 2 method

sub _rpcnot_didChangeConfiguration {
    ...
}

sub _rpcnot_didChangeWorkspaceFolders {
    ...
}

were symbols for workspace are populated, I am trying to figure out how and when to trigger them form 'neovim client'.

[PrajitP]

It turn out LanguageClient-neovim I am using does not support workspace/workspaceFolders feature.

Perl::LanguageServer::Parser->background_parser() only parse workspace from 'workspace folder'.

Not sure if it's write design, but I think it should also parse 'rootURI' directory as it is consider as default root if 'workspace folder' is missing.
