I think that irb is one of the most useful tools in the rails toolbox. It allows me to quickly determine how something works, sample results (for putting into blogs, don’tcha know) and makes me a more effective ruby developer.
One of the nice things about irb is it’s .irbrc file where you can place startup commands. I’d like to share mine (and ask for others to share their favorite .irbrc tools/contents.
