Now I want to make it so that when I go to localhost:3000/hi/anita, the page says "Hi anita", but when I go to localhost:3000/hi/bob, it says "Hi bob". Of course, I don't want to make anita and bob actions. You get the idea. ...

I have an instance of the Builder pattern in my project right now. Currently, the supported output format is CSV, however I would now like to include YAML. Easy, I thought. I have all of the supporting code in to make the type change. I'm finding myself to be in a bit of a complex. The intent of using the Builder pattern was to construc...
Hey all, I am not a programmer, so please be forgiving if my problem is fairly easy to solve for many of you (yet I still might find it confusing). The problem I am having is with ci_reporter, a gem for use with Watir and Test/Unit. It is outputting the test results from a Watir test to an xml file. Great so far. Unfortunately I can...

I'm in the process of documenting a Ruby project with rdoc, and I discovered the darkfish rdoc formatter. I really like it, but the :call-seq: tag no longer works. Instead, it puts the literal string :call-seq: in the documentation and then formats the call sequence itself as a code block. I don't want to just take all of the :call-se...
