v2.0-a079-be5df98 - not operator and Hotkey function Topic is solved

[Ragnar]

Unlike the "!" operator, the "not" operator doesn't work. Is this intended?

The following example(s) from _If.htm:

Code: Select all

; Example 1: Adjust volume by scrolling the mouse wheel over the taskbar.
#If MouseIsOver("ahk_class Shell_TrayWnd")
WheelUp::Send "{Volume_Up}"
WheelDown::Send "{Volume_Down}"

MouseIsOver(WinTitle) {
    MouseGetPos ,, Win
    return WinExist(WinTitle " ahk_id " Win)
}

; Example 4: Dynamic hotkeys. Requires Example 1.
NumpadAdd::
Hotkey "If", MouseIsOver("ahk_class Shell_TrayWnd")
if (doubleup := !doubleup)
    Hotkey "WheelUp", "DoubleUp"
else
    Hotkey "WheelUp", "WheelUp"
return

DoubleUp:
Send "{Volume_Up 2}"
return

throws the following error if I press NumpadAdd on the taskbar. Did I do something wrong here?

Code: Select all

Error:  Parameter #2 must match an existing #If expression.

		Line#
		003: Return
		004: Send "{Volume_Down}"
		004: Return
		006: {
		007: MouseGetPos "", "", "Win"
		008: Return WinExist(WinTitle " ahk_id " Win)
		009: }
--->	013: Hotkey "If", MouseIsOver("ahk_class Shell_TrayWnd")
		014: if (doubleup := !doubleup)
		015: Hotkey "WheelUp", "DoubleUp"
		016: Else
		017: Hotkey "WheelUp", "WheelUp"
		018: Return
		021: Send "{Volume_Up 2}"
		022: Return

The current thread will exit.

Edit: Ah sorry, wrong topic. I thought this refers to the new version generally, not just to the loop statements.

I split the topic.

No, the not operator failing to work is not intended.

Many of the examples haven't been updated with the new syntax (perhaps the majority of examples, except on the main pages like "Scripts" and "Variables"). The syntax shown in that example is incorrect. The Hotkey function needs the text of the expression, not the result of evaluating it. Hotkey "If", MouseIsOver("ahk_class Shell_TrayWnd") calls MouseIsOver() immediately and passes the result to the Hotkey function.

[lexikos]

The not operator has been fixed in v2.0-a081.

Thanks.
