Find Ruby step definitions when defined by a step() method

[henrahmagix]

Turnip defines steps with the method step, it doesn't (currently) support Given/When/Then/etc. Also those method names aren't Ruby-like because they start with a capital letter, so even aliasing them doesn't feel great, though it is a workaround.

It'd be lovely if the Cucumber language service could find these step '...' do; end definitions =)

🤔 What's changed?

step has been added to the list of method names matched by the defineStepDefinitionQueries in the Ruby language.

⚡️ What's your motivation?

This allows the Cucumber LSP to find step definitions in a repo using https://github.com/jnicklas/turnip, e.g.

module FeatureSteps
  step "I am logged in" do
    login(@user)
  end
  # ...
end

🏷️ What kind of change is this?

• ⚡ New feature (non-breaking change which adds new behaviour)

♻️ Anything particular you want feedback on?

It'd be lovely if this expression could be passed in by configuration, so we can easily match our own definitions in our own usages ☺️

Sorry, I just made this through GitHub's fork-and-edit. Is it worth adding to the tests, when it's an addition of a method name to a regexp? Also I'm not sure if this should be documented.

I'm happy to do all that if it's necessary; so far this is fixing just my own situation, I don't know how prevalent VS Code + Cucumber extension + Ruby repo + Turnip gem usage is, and therefore how important it is to document this.

Perhaps I could work on a refactor to get this pattern into configuration, if y'all would accept that? That would definitely be important to document and test. Might be a bit of work to acquaint myself with the language-service repo and the language-server repo, like which provides configuration and how it gets passed through, and how to provide the current pattern as a default from the vscode repo =)

Thanks in advance, snance,
