This kind of thing is really difficult to do in Ruby. (I'm guessing you're looking for something similar to the autocomplete lists you've used in Visual Studio, Eclipse, or another IDE?)

Because classes can have new methods added at runtime, individual objects can have methods added or removed at runtime, and so on and so forth, there's no easy way to reflect and grab that information while you're typing.

Having said that, try the following in irb or script/console (not sure how to do that on Heroku)

>> object.methods.sort

>> object.methods.sort.grep /something/

(where /something/ is a regexp representing the name or part of a name of what you're looking for).

Hope that helps!
