Being a noobie to AHK, my code tends to be a little longer than it can be. Going through other people's code and reading the command list, I've come across some nice ways of shortening my code and I thought it'd be nice to start a thread compiling all of the techniques.
Feel free to add/correct and of techniques!
TERNARY OPERATORS
Code:
; Original code
If var = 1
i = 1
Else
i = 2
; Shortened code
i := var = 1 ? 1 : 2
I also found the ternary operators useful for if statment message boxes.
Code:
; Original code
If var = 1
MsgBox, Var equals 1!
Else
MsgBox, Var doesn't equal 1!
; Shortened code
i := var = 1 ? "It exists!" : "It doesn't exist!"
MsgBox, % i
If the message boxes are long, you can use the ternary operators to continue the line above (although, this example doesn't make the number of lines any smaller).
Code:
i := var = 1
? "Why does var have to equal 1?"
: "Var does not have to equal 1 all of the time"
MsgBox, % i
Has anybody figured out how to shorten Else If statements?
ASSIGN OPERATOR ".="The ".=" operator is very useful when creating parsed lists in loops.
Code:
; Original code
Loop, 10
i := i "|" A_Index
; Shortened code
Loop, 10
i .= "|" A_Index
BOOLEANInstead of having to check if boolean values equal 0 or 1, you can just drop the "= 1" in the if statment and check if the boolean is not blank or zero.
Code:
; Original code
WinWait, Untitled - Notepad, , 1
If ErrorLevel = 1 ; i.e. it's not blank or zero.
MsgBox, The window does not exist.`nErrorLevel: %ErrorLevel%
Else
MsgBox, The window exists.`nErrorLevel: %ErrorLevel%
; Shortened code
WinWait, Untitled - Notepad, , 1
If ErrorLevel ; i.e. it's not blank or zero.
MsgBox, The window does not exist.`nErrorLevel: %ErrorLevel%
Else
MsgBox, The window exists.`nErrorLevel: %ErrorLevel%
