What I'm trying to find out is whether there is some sort of equivalence to what I see in Groovy as ExpandoMetaClasses. I've been reading about Open Classes but I can't quite see what level of scoping Ruby allows of the class modifications. Borrowing an example from the blog above, in Groovy, I could modify Java's String class and add ...

We're starting to standardise on a Ruby-based testing framework, having had some very good results out of RSpec and Cucumber-based testing recently. As this is a large enterprise, we're going to attempt to put together a "standard" set of Ruby gems for testing, knowing we're only ever going to get it ~90% right because of the broad mix ...

I am working on a small program to grep Tomcat logs and generate pipe-delimited CSV files from the pertinent data. Here is a simplified example that I'm using to generate the line...
I have scripts that use "#!/usr/bin/env ruby" but I've switched to using Ruby Enterprise Edition instead of the default ruby that is included with Ubuntu server. Thus, the scripts freak out when I try to run them. How can I add the Ruby EE path to /usr/bin/env? ...
