assignment in V2

[isurface]

Since V2 removed "=" assignment, I cannot use the following code.
var =
(
line1
line2
line3
}

but the replacement which I know is too complex. such as:
var := "line1`n"
. "line2`n"
. "line3`n"

Who can tell me a simple one?

Thanks.

This works in 1.1

Code: Select all

var :=
(
"This is a string.
that is a very long string
and it spans multiple
lines. "
)
MsgBox, % var

var :=

"This is a string.

)
MsgBox, % var

Thanks, but V2 does not support this format.

This works for me

Code: Select all

s := "
(
	Begin
	continuation
	section
)"
Msgbox %s%

[jethrow]

Code: Select all

Assign, var,
(
line1
line2
line3
)


Assign(p) {
	return p
}

Thanks, but V2 does not support this format.

It just needs the Q option, so that the second quote mark is interpreted as a close-quote.

Code: Select all

var :=
(Q
"This is a string.
that is a very long string
and it spans multiple
lines. "
)
MsgBox, % var

Of course, the previous two posts show better alternatives.

Thanks all, they are just what I wanted.

Hi Jethrow,

Could you explain this a bit more? What's "comma" means here? I have never seen this syntax.

Code: Select all

Assign, var,
(
line1
line2
line3
)


Assign(p) {
	return p
}

User-defined function(s) in v2 can be called in command syntax. jethrow defined an assign function and called it in command syntax. Since the function is returning a value, calling it in command syntax requires an OutputVar, in this case var. Comma is needed as it requires 2 parameters: OutputVar and Value(value to assign). You can omit the first comma after assign as AHK has smart comma handling

It's one of the new amazing features of AHK v2 - any function can be called as a command, and any command can be called as a function. Really, they are just executable statements. So, the following are 2 statements are equivalent:

Code: Select all

var := Assign("value")
Assign, var, value

Assign(p) {
    return p
}

Amazing, very concise. It looks like ASM.

Code: Select all

add, var, 2, 3
add(p, q) {
    return p + q
}
