RegEx 111) Ignore Whitespace in AutoHotkey Regular Expression

Ignore Whitespace in AutoHotkey Regular ExpressionLong 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!

RegEx 110- Example using AutoHotkey Regular Expression on naming convention

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.

RegEx 108-Return your match in AutoHotkey Regular Expressions match object

AutoHotkey Regular Expressions match objectNeed to get additional information about your RegExMatch?  Why not return a AutoHotkey Regular Expressions match object?  Having your data returned in an object allows for some great information like: Length, location, name of subpattern, etc.  With AHK  you can use the O) option to store the matches into an AutoHotkey object.  The below video walks through how to do it and gives you a clear example how to access it once it is created.

RegEx 107- Using POSIX in AutoHotkey Regular Expressions

POSIX in AutoHotkey Regular ExpressionsOnce 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
