Enumerable iterators (why I love Ruby part 2)

January 16th, 2008 | 1 Comment »

Got myself a sleepless night recently and killed some time reading the Rubyisms in Rails book. The chapter about Iterators was particularly pleasant, reminding me the beauty of Ruby’s Enumerable class - feels so Lisp-ish and Scheme-ish to write stuff like col.select{..}.collect{..}.join(”, “)
For the curious, here’s a cool excerpt from the book, with Enumerable’s most […]

Ruby Metaprogramming part 2

November 7th, 2007 | 1 Comment »

Last time I discussed Ruby and metaprogramming, I was trying to stay DRY (Don’t Repeat Yourself) while coding some very similar-looking methods. The solution, then was to use class_eval to dynamically add methods into the current class, the way attr_accessor and it’s peers already do.

TwitterYM - tiny ruby Yahoo Messenger status Twitter updater

April 4th, 2007 | 20 Comments »

Challenged by a commenter on my website, I spent the last half an hour coding a tiny application that updates your Yahoo Messenger status with your latest Twitter status. It’s Windows only (I’m a Mac user myself, and twitterific does a good job for it).

Grepping in Ruby

April 3rd, 2007 | No Comments »

You can’t call yourself a programmer if you never used Grep (or diff, or wget, or regular expressions for the matter). I couldn’t call myself a programmer till the fourth year of college, btw..
