Capybara code completion in RubyMine

Is there a way to get some help from RubyMine's code completion when using Capybara in Cucumber's step definitions? I'm new to Capybara, so not having to check the reference site all the time would be really helpful.

The best I can get at the moment is by explicitly calling Session.new, something like:

session = Capybara::Session.new(:rack_test, my_app)

This way Ctrl+Space after session. shows me methods from Capybara::Session (only) so at least I know it's somehow reachable. But that's not how I really use Capybara in my step definitions. I thought that helping the type inference engine by manually annotating page could do the trick, but I suppose all this DSL magic 开发者_JAVA百科is too much to handle.

So basically, is it somehow possible to have

page.<Ctrl+Space>

pop up with all the exposed DSL methods? RubyMine API maybe? Or, as an alternative, some other way to bring the reference docs closer (I don't think RubyMine supports external docs in the IDE yet)?

As of RubyMine 8.0.3 the answer is no, RubyMine does not complete Capybara methods following page. in Cucumber step definitions, at least not when Capybara is included in Cucumber via the cucumber-rails gem. I don't see a feature request in the RubyMine issue tracker; someone could add one if they like.

Note that cucumber-rails, at least, includes the Capybara DSL in the Cucumber world, so you don't need to type page. in front of Capybara methods. You can just call visit, fill_in, etc. as self methods. I wouldn't want unnecessary page. in my step definitions just for the sake of RubyMine completion.

Unfortunately, RubyMine also doesn't include Capybara methods in the list of names it completes when you invoke completion in a step definition before you type anything. It does include Capybara methods in the list of names it completes when you invoke completion twice (all names in all available code), but since that list is so long it's only helpful if you already know the method you want already, or at least a correct prefix.

Finally, found a solution.

I am using Cucumber with Capybara and I included all the matchers I wanted to code complete in /features/support/spec/spec_helper.rb. Cucumber auto-loads everything in this file. I bet there are other places you can include these statements if you aren't using cucumber.

# Needed for RubyMine code completion
include Capybara::Node::DocumentMatchers
include Capybara::Node::Matchers
include Capybara::SessionMatchers
include Capybara::RSpecMatchers
include Capybara::RSpecMatcherProxies

For your specific case: include Capybara::DSL

Then
