Revised Benchmarking

I noticed something when trying out the benchmarking feature today. It didn't seem to be any slower when matching ten results vs just one. So I knew something was up.

After looking into it I still can't fully explain what was happening. Perhaps there was some lazy loading going on, I'm not sure.

But I reworked the code today and it seems to scale properly now. It will slow down with more complex regular expressions, as well as target strings with more matches.

For those who are curious about how I'm performing the benchmarking now, here's the code:
Dim startTime As DateTime = Date.Now

Dim _regexBenchmark As New Regex(strRegex, _regexOptions)
For i As Integer = 0 To iBenchmarkIterations
For Each _match As Match In _regexBenchmark.Matches(strTargetString)
If _match.Success Then
' Do nothing
End If
If Benchmarking.CancellationPending Then
e.Cancel = True
Exit For
End If

e.Result = Date.Now.Subtract(startTime).TotalMilliseconds

I'm not sure how many of you use the benchmarking feature but I hope this sudden change doesn't mess anyone up.

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.

Installer for Desktop version of Regex Hero

As Firefox just dropped support for Silverlight I really needed a solution for Regex Hero. So I created an installer for it. It's still Silverlight, but by using the installer you can install it directly to your computer and never need to open it in a browser. If you visit and don't have a browser that supports Silverlight (IE is the only one left), then you'll see download links for 64-bit and 32-bit versions of the installer. When you install it you'll see a link over on the right hand side that says "Activate Regex Hero". This process connects your desktop version of Regex Hero with your online account. So if you're a licensed user this is how you'll gain access to all of those licensed features. Note: Currently there will be a security warning when you try to run either one of these installers. I'm in the process of obtaining a code signing certificate and will update them as soon as possible. You may be wondering a

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
