Create Regexes The Easy Way with RegexMagic

RegexMagic makes creating regular expressions easier than ever. While most regex tools merely make it easier to work with regular expressions, with RegexMagic you don't have to deal with the regular expression syntax at all. RegexMagic generates complete regular expressions to your specifications.

First, you provide RegexMagic with some samples of the text you want your regular expression to match. RegexMagic can automatically detect what sort of pattern your text looks like. Numbers, dates, and email addresses are just a few examples of the wide range of patterns that RegexMagic supports. By marking different parts of your samples, you can create regular expressions that combine multiple patterns to match exactly what you want. RegexMagic's patterns provide many options, so you can make your regular expression as loose or as strict as you want.

Best of all, RegexMagic supports nearly all popular regular expression flavors. Select your flavor, and RegexMagic makes sure to generate a regular expression that works with it. RegexMagic can even generate snippets in many programming languages that you can copy and paste directly into your source code to implement your regular expression.

RegexMagic doesn't automatically generate regular expressions on magic alone. But it sure makes things a lot easier by allowing you to work with your data instead of the cryptic regex syntax.

On top of that, EditPad Pro's syntax coloring and file navigation schemes are also built on regular expressions, including the ones that ship with EditPad Pro.
