Once you get used to the RegEx symbols it is pretty easy to follow however, those not familiar with it, will often be perplexed by what it is doing. I will sometimes use POSIX in AutoHotkey Regular Expressions to help layman read my code. While it is easier to read, it does add considerable length to the expression (but don’t confuse length with the speed of it working. I doubt there is a correlation in this case)
POSIX (pronounced PAH-zihcks) is an acronym for Portable Operating System Interface from UNIX
