[SUGGEST] Object callable property Topic is solved

[_3D_]

Due to no simple way in AHKv2.0 to be created object method I suggest Object to have mechanism to direct call "callable properties" (properties contain reference to function).
Explain: Let Object have property that contain reference to functions

• Get - return value
• Set - set value
• Call - return result from calling reference

And in code example:

Code: Select all

class proto { ;test class =====================================================
	__Call(name, para) { ;call callable property ------------------------------
		try return this.%name%.call(this, para*)
		catch
			throw { message: '<' this.__Class '> has no method or callable property <' name '>' }
	} ;------------------------------------------------------------------------
	me_0(a) => A_ThisFunc ': ' a
	pr_0[a:=''] {
		get => A_ThisFunc ': ' a		  ;callable prop [parameters] 
		set => ''						  ;callable prop (no returun result)
	}
	pr_1:= (this, a) => A_ThisFunc ': ' a ;callable prop (ref)
} ;============================================================================

b:= proto.new()						;tests -------------
MsgBox(b.me_0(123))					;123			(ok)
try b.pr_0							;proto.__Call	(ok)
catch e
	MsgBox(e.message)
;:= <identificator>	;get
;<identificator> :=	;set
;<identificator>	;call
MsgBox(b.pr_0[234])					;.get			(ok)
MsgBox(b.pr_0:=345)					;.set			(ok)
MsgBox(b.pr_1(456))					;.call			(ok) <<< suggest

In short - let property have extra feature to be called (.get|.set|.call)

This would be a step backwards, back to conflation between methods and properties, which we've finally got rid off. A better, and more logical, solution would be to allow simpler syntax for defining methods. I think lexikos said somewhere he might add something like { m() => expr }, I also think that local classes have been mentioned. In particular the latter would great.

In the mean time, the current situation is still very workable, either use definemethod or %expr%(), eg, %obj.prop%().

Cheers.

Or a custom object, eg use __call,

Code: Select all

class x {
	static __call(n, p) => %(this.%n%)%(this, p*)
}
o := { base : x, prop : (t)=>msgbox()}
o.prop()
