Can't call a function in a map with the point operator [BETA]

[anonymous]

I love the point operator in maps. But this don't work with functions. The first version generates an error:
"The requested action with this object has failed."

$oPerson = Person("John Smith", 30)

$oPerson.Print($oPerson) ; version 1

$oPerson["Print"]($oPerson) ; version 2

$func = $oPerson.Print ; version 3
$func($oPerson)

Func Person($sName, $iAge)
	Local $oObj[]
	$oObj.Name = $sName
	$oObj.Age = $iAge
	$oObj.Print = Person_Print
	Return $oObj
EndFunc

Func Person_Print($oThis)
	ConsoleWrite($oThis.Name & ": " & $oThis.Age & @LF)
EndFunc

Can you fix it?

Use this:

($oPerson.Print)($oPerson) ; version 1

Note that Au3Check chokes on this.

Thx jchd18. It's a good idea. With the following code, can I deactivate Au3Check:

#AutoIt3Wrapper_Run_AU3Check=N

[jchd18]

Exactly.

It would be very hard to make the version 1 construct work. Look at this:

$X.Y($p)

How could the interpreter understand that otherwise that first try to evaluate

Y($p)

as a function then

$X.(Y($p))

Take into consideration that a non-member function Y could exist. AutoIt is only an interpreter, there is no actual compilation.

Replying to jchd18:

Y($p)

as a function then

$X.(Y($p))

Because the grammar doesn't allow that. It works for COM objects, doesn't it?

[jchd18]

My "wrong grammar" was just an illustration of what could happen.

Also don't compare AutoIt Maps and COM objects. Objects do have declared methods while Maps are simpler structures having only passive member variables. One other good illustration of the difference is that you had to pass "this" explicitely as a parameter to the pseudo-member function (indeed: a member variable which happens to hold a function pointer).

Replying to jchd18:

My "wrong grammar" was just an illustration of what could happen.

The interpreter already supports the syntax for COM objects and maps (it doesn't try to execute Y($p) first), but it doesn't support it's execution for the special case of maps:

Local $oHTTP = ObjCreate ("winhttp.winhttprequest.5.1")
$oHTTP.Open ("GET", "http://www.AutoItScript.com")
; OK
$oHTTP.bogus ()
; Error: The requested action with this object has failed.

Local $map []
$map.f = f
$map.f ()
; Error: The requested action with this object has failed.

Please undo the status change.

Please don't misunderstand, I didn't create this ticket and it wasn't my intension to use maps as objects.

Hi,
I recheck with the latest beta and I get the following results so I assume it is OK
