How does one figure out where a definition of a function is given its call in Ruby on Rails code? For example, let's suppose, I didn't know what config/routes.rb is for. And I was looking at it and wanted to know what the function get does. It's not defined in routes.rb itself. There are no includes, requires or inheritance. How would one know what functions named get are available in that scope and which one of them would be called at runtime? I'm looking for a systematic way applicable to an arbitrary file in a Rails project calling arbitrary function that could be part of Rails or dependency gem.
-- When I tried 'Go To Definition' of the get in RubyMines, it popped up a list of about 100 options of what i could be. Is there an IDE that's better at this than RubyMine?
As for me, I can't even come up with a search terms to get something resembling an answer on google. That's why I humbly request your help. thanks.
