RegEx or Regular expressions are a syntactical shorthand for describing patterns. They are used to find text that matches a pattern, and to replace matched strings with other strings. They can be used to parse files and other input, or to provide a powerful way to search and replace.

RegExes are extremely useful, but the syntax can be hard to recall. Check out our “Python Regular Expressions Cheatsheet” to help point you in the right direction when building RegExes in Python.

Working With Regexes

Even if you are already a regex wizard, juggling between the different regex implementations between programming languages can be tricky. Fortunately, ActiveState’s Command Line Tool has an Rx Toolkit that supports Perl, Python, PHP, Ruby, JavaScript, and Tcl regex syntaxes. Write one regex, test for all languages right from Komodo IDE! Just click on the little icon to the right of the “Regular Expression” input box to switch between implementations.

Komodo IDE is a great product. My favourite feature is the regex generator/tester. It’s saved me heaps of time and aggravation when coming up with complicated regular expressions to get through weblogs and the like.
