I can’t tell you the # of times AutoHotkey Variadic Functions come in handy

AutoHotkey Variadic FunctionsAutoHotkey Variadic Functions can be incredibly handy when you don’t know the exact number of parameters.   The below example shows some simple math where you can pass any number of parameters to be added.  It also demonstrates how you can use MaxIndex() to determine how many parameters were passed to the function.

	loop, % x.MaxIndex() ;Loop over the # of parameters that exist
		Indiv.=	x[A_Index] "+"
	
	return SubStr(Indiv,1,(StrLen(Indiv)-1)) "=" tot ;use substr to remove the last + sign

Streamline your code by Utilizing the #Include command in your AutoHotkey Library

Include command in AutoHotkeyAs 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 command you can specifically tell AHK to look in a given file.
