** Now more than just a cheatsheet. You can write and test your Regular Expressions inside the app! **

Even seasoned developers need a quick refresher course in Regular Expressions from time to time. The RegEx Cheat Sheet for iPhone and iPod Touch is designed to address that need. Use it as a quick reference for topics you’ve already learned but need a few reminders on, or if you’re still a beginner to Regular Expressions, use it to better understand what RegEx has to offer.

This is a native app, not just a link out to internet references. It's searchable and has an easy to use interface that helps you quickly find what you're looking for. The categories are useful and well defined. The cheatsheet includes:

* Matching: Normal Classes [...] and [^...]
* Matching: Any Character dot (.)
* Class Shorthands (\w, \d, \s, \W, \D, \S)
* POSIX Character Classes (about POSIX, [:alnum:], [:alpha:], [:blank:], etc.)
* Unicode Properties
* Unicode Combining Sequences (\X, and the standard properties list - properties and meanings)
* Anchors and Zero-width Assertions (start and end of line/string, start of match, would boundary, look ahead and look behind)
* Comments and mode modifiers
* Grouping and Conditionals
* and many more

To make this cheatsheet useful in the field, we've included a collection of commonly used patterns:

* Removing leading and trailing white space
* Valid HTML hex code
* U.S. SS#
* U.S. Zip codes
* U.S. Currency
* Date/Time
* Dotted Quad IP address
* MAC address
* Email Addresses
* HTML URLS
* and many more

Most importantly, we've covered the ways in which different languages use RegEx. The cheatsheet includes language specifics for:

* PERL
* JAVA (java.util.regex)
* .NET and C#
* PHP
* Python
* Ruby
* JavaScript

Unlike apps that cobble together random references from the web, this cheatsheet is written and reviewed by professional web developers that use Regular Expressions on a daily basis. We keep up with changing specifications and provide free updates in the same simple, easy to use format.
