Feature: Support graphql tagged heredoc string literals in non-js files

Thanks for making this awesome plugin. Works great for our js codebase

However our graphql api is written using graphql-ruby and so all of our graphql specs are Ruby files. In these files we define heredoc string literals like this:

# spec/whatever_spec.rb

<<~GRAPHQL
  query Whatever {
    whatever {
      id
    }
  }
GRAPHQL

Would it be possible to support Ruby files with this plugin?

If so, is it something a new contributor would be able to tackle? I wouldn’t mind taking a stab at implementing it if someone gives me a few pointers where to start.

Thanks again!

@acao Still very interested in this but not sure how to start or how to test. Also I have no need for syntax highlighting, as that’s covered by another plugin I’m using https://marketplace.visualstudio.com/items?itemName=kumar-harsh.graphql-for-vscode

parsing ruby on the language server side for full-featured language support is another matter

Would we actually need to parse the Ruby language just to examine query strings? I found this opal package, something like that? https://github.com/opal/opal

the language grammar files are where this happens for highlighting. they are json files with regular expressions for selecting tokens. if you see a graphql highlighting mode another extension has, you can open a PR

for actually supporting language features other than highlighting, that logic lives in the seperate LSP server repo that this repo depends on
