Improved Auto-Saving

I knew there was room for improvement in the auto-saving feature. So I've made some changes that make the process faster and more efficient.

As I talked about last time, the synchronous saving method just had to go. So I made it asynchronous for the 3 main text boxes: regular expressions, replacement string, and the target string. Now that it's asynchronous it doesn't slow you down as you type, even if the target string is quite long. Now, isolated storage does have a limit of 1 MB. So to make good use of space I've imposed a 200,000 character saving limit on these 3 text boxes. Anything beyond that will be truncated.

The other change is related to the way I auto-save the settings (checkboxes, expanders, etc). Before I was doing something which was a little bit stupid, as it turns out. I was saving these settings into an XML file in isolated storage. And to do so I had added the System.XML.Linq assembly into Silverlight. Well I found that this was unnecessary as isolated storage has a very nice IsolatedStorageSettings class that's perfect for storing the little stuff. Now that I've switched to this method, I've removed the Linq assembly. And that has brought the size of Regex Hero from 223 KB bytes down to 163 KB -- a 60 KB savings. So these changes make it faster, more responsive, and better in every way.

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.

Silverlight 4 Coming in April, or Maybe Sooner

The exact release date has not been announced. But Visual Studio 2010 RTM is coming out in April and I think it's safe to assume that Silverlight 4 will be released no later than that. Each release of Silverlight has brought massive improvements over the previous version. And once again, Silverlight 4 does not disappoint. There is a long list of improvements but the ones that I think that will affect Regex Hero are as follows: RichTextBox My plan is to use this in place of all 4 major textboxes in Regex Hero. The new RichTextBox has built-in multiple undos & redos, so I can ditch my home-brewed code. It should be nice to use for syntax highlighting for the regular expressions I intend to create. It also has a built-in API to determine the pixel position of the text. I should be able to use this API and build a new highlighting scheme based off of it. This should do a couple things. First, I should be able to finally fix the problem I had with the ScrollViewer and

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.
