In today’s webinar we helped troubleshoot some examples from attendees.
Video Hour 1: High-level overview: Hour 1:
Video Hour 2: Q&A: Hour 2
The script showcase was Lexikos’ DebugVars which can be found here
During the webinar Dale shared a script which would help him select the “upper-level” of a key by long-pressing the key. Cap’n Odin rewrote it (twice) and you can see the final version here.
If you have any suggestions for upcoming webinars, please let us know!
Long Regular Expressions can be very difficult to read and revise when you come back to it later. Using the X) option allows you to Ignore Whitespace in AutoHotkey Regular Expression and insert comments as well as spread out your RegEx over multiple lines.
Below is the example code I use to ignore the whitespace in AutoHotkey RegEx which is demonstrated in the video below. It is a great way to make your code easier to read & maintain. It may take a few months until you revisit your RegEx but, when you do, you’ll thank me for it!

I’ve found the best way to learn RegEx is to actually play with it. For that reason I’m making a few videos that will demonstrate actual use-cases. In this example I demonstrate applying an AutoHotkey Regular Expression on naming convention. As I show in this video, there are a ton of different ways you can write a Regular Expression that will capture what you need. There isn’t a “right” & “wrong” way, just make sure what you use is reliable and makes sense to you.
Much of the syntax in AutoHotkey RegEx is straightforward. Having said that when trying to include double quotes (“) in my pattern I regularly had difficulties. In the following video I demonstrate three separate ways you can escape double quotes in AutoHotkey Regular Expressions.
And this is the syntax I used escaping quotes in AutoHotkey Regular Expressions in making the video
