Invalid variable declaration ? Topic is solved

[WalkerOfTheDay]

Hi, I'm still transitioning to V2 and now and then I run into thing I don't understand, like below example.
Why is Global Line++ throwing an error ? In this case ?
I declared the variable as global at the top of the script, so what causes the error ?

Code: Select all

#Requires AutoHotkey v2.0
Global Line := 1


^2::
{
    ;global Line                := Line+1    ; <<<< This works
    Global Line++             ; <<<<<< This throws the error [color=#FF0000]Invalid variable declaration[/color]
}

Hello,

My hunch is that Global must always be followed by a variable name alone, though it can then also be followed by other assignment operators separately.

Code: Select all

Global x += 1

I'm not sure whether this is considered a bug in AutoHotkey.

According to the list of expression operators, ++ is not defined as an assignment operator as += is.

Any assignment operator can be used

Oke thank you.

Excuse my ignorance, but when I replace ++ by += I get this error: Error: Expected a String but got a Func.

Code: Select all

#Requires AutoHotkey v2.0

global Line := 1

^2::
{
    global Line+=
    MsgBox Line
}

As with all other assignment operators, that operator would be followed by an expression used for the assignment, such as 1. See my script for an example.
