Overly sensitive to startup?

[kwerle]

I sometimes get the following when starting up. It may depend on cursor context & timing.

NoMethodError: undefined method `refs' for nil:NilClass
  /app/lib/language_server/project.rb:15:in `find_definitions'
  /app/lib/language_server/definition_provider/ad_hoc.rb:12:in `call'
  /app/lib/language_server.rb:139:in `each'
  /app/lib/language_server.rb:139:in `flat_map'
  /app/lib/language_server.rb:139:in `block in <module:LanguageServer>'
  /app/lib/language_server.rb:45:in `block in run'

  exe/language_server-ruby:8:in `<top (required)>'

Could you give me the project which you opened?

[kwerle]

Literally any project will do (note that this is using Atom). You just have to start typing before all the parsing is done. Then when the parsing is finished the next character you type will cause it to blow up. If you must have a named project, this one will do fine. This is 100% repeatable.

I can reproduce this inside this repository.

I tried to go to definition with result on line 70 in this file. I expected it to take me to the declaration right above it, but instead I see this stack-trace:

/usr/local/lib/ruby/gems/2.5.0/gems/language_server-0.11.0/lib/language_server/project.rb:15:in `find_definitions': undefined method `refs' for nil:NilClass (NoMethodError)

	from /usr/local/bin/language_server-ruby:23:in `<main>'

Note that I didn't edit the the file before sending the definition request.

I've bailed and started https://github.com/kwerle/ruby_language_server - which I use with Atom. If you are interested in helping I'd be happy to do some vscode integration.
