Functions in AutoHotkey are a great tool to have in your bag! They can definitely help simplify your code, ease re-purposing of code and avoid a lot of simple mistakes by keeping the variables local (instead of global). AHK Studio is an editor written in and for AutoHotkey. It helps both noobs & gurus write great code and is worth a deep look!
The below video reviews a few tips & tricks for working with functions.
As I previously reviewed, functions in AHK rock! The below video demonstrates how easy it is to use the utilize the include command in AutoHotkey to leverage functions & libraries that are not in your main file.
Without using the include command AHK will first look in your local library, then look under the myDocuments\AutoHotkey\Lib\ folder and finally under path-to-running-AutoHotkey.exe\lib\.
By using the #Include Directive you specifically tell AHK to “include” the file in your script.
AutoHotkey functions are a true gem that help streamline your code, make it more readable, easier to maintain, and avoid conflicts with other variables (because their scope is local by default. They take a little practice getting used to however they can save a ton of time and allow for re-using a ton of code. Don’t get hung-up on writing them at the beginning of your script. Often I go back after writing my script and realize I should have written a function in place of a subroutine.
My first video on AutoHotkey functions explains why & how you can use them.
