Improved TextBoxes With Better Whitespace Support

Today's update is all about whitespace. I've created a new textbox control for Regex Hero which is now being used for the 4 main textboxes: Regular Expression, Replacement String, Target String, and Final String.

The new features are as follows:
Figure 1: Matching Line Feeds

  1. Handles tab characters as it should. You can test this by entering \t in your regular expression and then hitting tab in your target string.
  2. Matching carriage returns or line feeds are now visible with a half-width character block (as seen in the figure 1).
  3. You may preserve the formatting of pasted text with the new "Preserve pasted formatting" option.  This will retain the existing line endings of your source text as was suggested about a month ago.
  4. Cycling through your matches with the up & down buttons is now much more responsive.

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 regexhero.net/tester 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

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.

Regex Hero Professional is Now Free

Regex Hero is now completely free!  I've been working on this tool off and on for the past 8 years. I spent a lot of time making it very powerful and easy for developers to create efficient regular expressions. Throughout most of this time it's been a paid product. However, with the added pressure of other free tools out there getting better all the time, I've finally decided to make Regex Hero free as well. Enjoy! Try Regex Hero at http://regexhero.net/tester/
