Regex Analyzer

Regex Analyzer
Regular expressions are one of those things that many programmers dabble with enough to understand the concept, but not enough to memorize the syntax. Code completion is a big step towards making things easier. Beyond that, sometimes an explanation written out in English is just what you need.

The new "Regex Analyzer" feature actually uses my existing parsing engine that I used for code completion to step through the regular expression and build a tree which explains, in English, every construct.  When you click a line in the explanation box, it'll highlight the corresponding section of the regular expression.

This feature is only available in Regex Hero Professional.

By the way, in addition to this feature, there have been a few more improvements in today's release...
  • Added a new menu with icons underneath the existing file menu for easy one-click access to common features.
  • Moved the spot where the open & save dialogs and all of the tools appear just underneath the menu.
  • Added a "split" mode where the target string is split into lines wherever a match is found.
  • Fixed a bug where copying & pasting lines from a saved regular expression or target string would trim the line feeds.

Regex Hero for Windows 10 is Underway

Awhile back I began working on an HTML5 / JavaScript version of Regex Hero . However, it was a huge undertaking essentially requiring a complete rewrite of the entire application. I have not had enough time to dedicate to this lately. So I've begun again, this time rewriting Regex Hero to work in WPF. It'll be usable in Windows 10 and downloadable from the Microsoft Store. This is a much easier task that also has the advantage of running the .NET regex library from the application itself. This will allow for the same speedy experience of testing your regular expressions and getting instant feedback that Regex Hero users have always enjoyed. I expect the first release to be ready in Q4 of 2019.

Optimizing Your Regular Expressions

Regular expressions will backtrack.  That's an unfortunate thing about them because backtracking can be slow.    And in certain (rare) cases the performance can become so awful that executing the regular expression against a relatively short string could take over a minute.  There's a good article about catastrophic backtracking over at . And today I created a video about all of this called  Regex Lesson 5: Optimization .  In the video I start with a very poorly written regular expression and make several improvements to it, using the benchmarking feature along the way.  By the end of the video I make the regular expression over 3 million times faster. In addition, today's update to Regex Hero provides a little message in the event that you encounter a regular expression that takes over 10 seconds to evaluate... And then last of all, I changed the benchmarking feature a bit.  In the past it would simply test your regular expression against

Regex Analysis Bug Fixes

All of these updates relate to the analyzer, so if you're not a Regex Hero Professional user, then this won't affect you. I received a report of an analysis bug  related to character classes.  The regex analyzer wouldn't handle opening brackets inside a character class properly. It's one of the finer details of the regular expression syntax.  You wouldn't think that [[abc] would be valid, but it is.  You don't have to escape the opening bracket inside the character class.  So now the analyzer interprets this as it should. I've also fixed bugs around interpreting the \x00 (hex), \u0000 (unicode), and \k<group>  (backreference) expressions. P.S. The major updates I mentioned recently are still in the works.  So the price for Regex Hero Professional is still $20 for now.
