While trying to navigate a large, unfamiliar application, I find a cross referenced browser invaluable. For statically typed languages, there exist a whole bunch: LXR, the browser part of MSVC IDE, etc. For Ruby, are there any? I realize that it won't be perfect, as you can't always know excatly where the method is defined. But a simple algorithm which would certainly be at least 80/20 would be: 1) If it is proceeded by a dot, it is a method name 2) To guess the class of any object: If you see: variable_name = CapitalLetter.something, you can guess that variable_name is an instance of CapitalLetter 3) To find a method definition, first look through the methods defined for that class (RDoc is already able to parse them), then look through the current file, then, through all the files required in. Failing that, link to a simple search page, listing all of the places where it is defined. For me, a simple browser like this makes all the difference navigating unfamiliar code. I have no experience with CTags - maybe it could be used to do something like this? --- PS For a radically different approach, how 'bout using Ruby to load the app in a sandbox, and reflect across the entire ObjectSpace to figure everything out? Could this be done? I know it's a lot of work - beyond the scope of my initial request - but, if it could, it could add code completion and refactoring to dynamic lang IDE's, something which many developers truely miss.

Huh?! I thought everyone would jump at this. Am I the only one who finds these type of cross references TREMENDOUSLY USEFUL?

Maybe because RDoc does most of the cross-references you want, if only you follow the rules *and* you can read the code. So you can use your normal browser :) Cheers, V.- -- http://www.braveworld.net/riva
