Regex Tree and Regex Building Blocks
RegexBuddy's regex building blocks make it much easier to define regular expressions. Instead of typing in regex tokens directly, just pick what you want from a descriptive menu. Use RegexBuddy's neatly organized tree of regex tokens to keep track of the pattern you have built so far.
When you need to edit a regular expression written by somebody else, or if you are just curious to understand or study a regex you encountered, copy and paste it into RegexBuddy. RegexBuddy's regex tree will give you a clear analysis of the regular expression. Click on the regular expression, or on the regex tree, to highlight corresponding parts. Collapse part of the tree to get a good overview of complex regular expressions.
Quickly and easily create and edit regular expressions. Mix manipulating RegexBuddy's building blocks and directly editing the regex pattern to suit your own skill and style. Rely on RegexBuddy as you rely on a buddy or coach to assist you.
Regex Tester and Debugger
Don't risk actual data with untested regexes. Copy and paste sample data into RegexBuddy, or open test files. Step through the search matches in the sample data, and get a detailed report about each match. Or highlight all matches to debug the regex in real time as you edit it.
If a regex doesn't do what you want, debug it by looking at the complete matching process, eliminating all guesswork.
Compare and Convert Regular Expressions Between Flavors
Compare your regular expressions between any number of all the regular expression flavors that RegexBuddy supports. Make sure your regex works with all the versions of the application you're targeting. Easily learn the differences between your usual regex flavor and a new flavor that you need to use next.
Convert a regular expression created for one application to any other application. RegexBuddy automatically substitutes equivalent syntax and warns you about any subtle differences in behavior between the two applications.
Never again wonder why a regex that works correctly with one application doesn't work in exactly the same way with another application.
Develop Efficient Software Quickly with Instant Code Snippets
Save time and code efficiently by using regular expressions when developing applications and scripts. With the proper regex, you can often do in a single line of code, or a few lines of code, what would otherwise require dozens or hundreds.
