I must admit that like most programmers, regular expressions trouble me sometimes. One day I shall purchase (and digest) Jeffrey Friedl’s superb book Mastering Regular Expressions – the definitive guide for anyone wanting to get to grips with regexes. Until that time, I shall use a great bit of software that Mike Howarth pointed me towards – The Regex Coach.
In brief, it is a GUI application that allows you to experiment with Perl compatible regexes as you type.It can run on both Windows and Linux and has many wonderful features:
- Matching regexes an input string with full control over the selection area
- Provides an info window with an English language explanation of you regex
- Sets out a visual parse tree of your regex
- Options to Split/Replace/Step
Regex Coach is developed by Edi Weitz and is available on his web site. The software is free to download and use, but I’m sure Edi would be pleased with a donation or two!
