Help me understand what the syntax of this code means

[mexican scientist]

I have no Idea what the syntax of this code is saying.

Code: Select all

~]::
SetTimer RBracket,% (RBracket:=!RBracket)?12500:"Off"

I was told this works like a loop that repeats a task every 12.5 seconds, but what I don't understand is the ",%" and the "?" used in the code. I read the SetTimer notes and there is no information about this. I want to understand this code so that I can modify it and make a better code; I am trying to make a code that does the following:

~]::
press MButton and wait 12.5 seconds
if ] is pressed again at anytime between the 12.5 second of wait, then press MButton and reset timer (so that the next ~]:: will press MButton and wait 12.5 seconds), However, if ] is not pressed, then wait the whole 12.5 seconds

The code that almost does the job is this:

Code: Select all

~]::
SetTimer RBracket,% (RBracket:=!RBracket)?12500:"Off"
IF !RBracket
	return
RBracket:
	sendinput, {MButton down}
	sleep, 50
	sendinput, {MButton up}
return

?: is called a ternary operator. "% " is called a forced expression.

I have no Idea what the syntax of this code is saying.

Code: Select all

~]::
SetTimer RBracket,% (RBracket:=!RBracket)?12500:"Off"

This is like an If/ else statement but in a single line that switches between the two options using a variable that switches between two states (True & False).

An example here.

Code: Select all

F1::MsgBox, % (Toggle := !Toggle) ? "First Option" : "Second option"
