[AHK_H v2] Macro Functions

[HotKeyIt]

I have implemented experimental macro functions.

Now a function definition can be prefixed with 'macro ' (followed by space, not tab!) to create a macro instead of function.
Macro will use caller's scope for all variables except for parameters, function parameters will be resolved to local variables.
Dynamic variable references will also use caller's scope.

Global and static variables are not supported in macros.

Code: Select all

myfun("MyValue")
fun("AnotherValue")
MsgBox var
myfun(value:=""){
	fun(value)
	MsgBox var
}
macro fun(value){
	var:=value
}

Let me know what you think about it

Deref function example

fun()
fun(){
MyVar:="AutoHotkey_H"
MsgBox deref("Calling deref ``% from %A_ThisFunc% in %MyVar%")
}
macro deref(__deref__,__out__:="",__set__:=""){
Loop Parse, __deref__, "%"
If __set__&&!__set__:=false
__out__.=%A_LoopField%
else if SubStr(A_LoopField,-1)="``"
__out__.=SubStr(A_LoopField,1,-1) "%"
else __out__.=A_LoopField,__set__:=true
return __out__
}

Alternative deref function example

fun()
fun(){
MyVar:="AutoHotkey_H"
MsgBox deref(["A_ThisFunc","MyVar"],"Calling deref ``% from `a in `a","`a")
}
macro deref(__vars__,__text__,__delimiter__,__out__:=""){
Loop Parse, __text__, __delimiter__
if A_LoopField
__delimiter__:=__vars__[A_Index],__out__.=A_LoopField %__delimiter__%
return __out__
}

This is nice.
Eg, to reduce index transform clutter in loops,

Code: Select all

loop 8
	Msgbox 2**i()
macro i(){
	return A_Index-1
}

This crashes,

Code: Select all

macro m(){
	0
}

an error would be nicer, or if it was just inlined
Cheers.

That seems to be a problem in v2, it is not related to macro, I have opened a bug report: https://autohotkey.com/boards/viewtopic ... 33#p158449
