Extract email address from text with Regular Expression in AutoHotkey

Extract email addressRegular Expressions are incredibly helpful for day-to-day tasks!  In this short video I demonstrate how easy it is to use a Regular Expression (RegEx) in AutoHotkey to extract email addresses from text.  The first half of the video shows how I use it to parse the haystack listed in the script.  The second half of the video I make a minor tweak and adapt it to work with any program that you can copy text to the clipboard.

Below is the code I demonstrate in the video

AutoHotkey Regular Expression on naming conventionI’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.
