I intend to make this post a running tally of useful regex’s that I use, but for now I just have one. This will extract a URL form a string. I’m using it to tinyurl URL’s in a twitter post that are posted from the Firebelly CMS. /(http|https):\/\/([a-z0-9]+)[-.]?([a-z0-9]+).[a-z]{2,5}(([0-9]{1,5})?[\/\?][[\S]]?)?/ix

So, there are lots of functions out there to do this, but this one is my favorite for a couple of reasons. It parses the entire query string as soon as you call the function, whereas other functions require passing in a parameter which the value for the parameter is then extracted from the query [...]

Here’s a quick checklist of the steps I just took to get all my web dev stuff set up on my new MacBook with Leopard. I do mostly Ruby on Rails work with some PHP stuff thrown in there, so we’ll go through installing MySQL, PHP, Rails, Git and Passenger.
