Please ask questions like these in Ask for Help.

nnnik, I don`t ask for help, I am disagree with object concept. So place of this post must be in "AutoHotkey v2 Development".

the mechanics have been reversed. previously, returning blank was the default and if u wanted protection against accidental reads of nonexistent properties u would have had to implement something custom in metaget urself. now its the other way around. presumably, noobs will be less likely to become...

In neither case is the target of the operation an already-initialized variable/field: this.stat:=!this.stat : This is a GET operation on a not-yet-existing field followed by a SET. Since it's reading from a field that doesn't exist it throws an exception. stat:=!stat : This reads an uninitialized g...

And again about __Get and Has but this time for classes. In AutoHotkey, variables are created simply by using them. ;In AutoHotkey, variables are created simply by using them. class Item { __New() { ;this.stat:= "" ;uncomment to init first this.stat:=!this.stat ;variable (object member) is NOT creat...

AHKv2.0-a108 Probably this is an old BUG. Let see next example: Gui:= GuiCreate() Gui.MenuBar:= MenuBarCreate() Gui.MenuBar.Add("&File", FileMenu:= MenuCreate()) FileMenu.Add("&Open`tCtrl+O", (*) => FileSelect()) FileMenu.Add("E&xit", (*) => ExitApp()) Gui.MenuBar.Add("&Help", HelpMenu:= MenuCreate...

How I think Object, Array and Map must work in AHKv2.0 (current version a108) Object ;Override Object -------------------------------------------------------------- ;Override Object.__Get -------------------------------------------------------- Object.Prototype.DefineMethod('__Get' , func("Object__G...

Array's prototype already has a __New method defined, it delegates to .Push() . Map does not, so define ur own constructor, either on Map or ur derived type. why this is and whether its subject to change, ask lexikos to find out still dont get this set/add nonsense. sure, an ahkcode if-check would ...

Could you show an example where a combined add/set instruction is useful for arrays in a real context?

Code: Select all

Map is initted as follows: myMap := Map( 'key1', 'val1', 'key2', 'val2', ) TY for this. i have no clue what u meant to express with "set/add" and this postincrement hodgepodge arr:= [2] loop 2 arr[A_Index]:= A_Index ;Invalid index (2) ;set value at index 1 ;add value at index 2 To work this must be...

I read and next class Array extends Object . arr[i] i can be any positive index, or a zero or negative value to indicate an index relative to Length, with -1 being the last element and 0 being Length+1. It mean: ;if index start from 1 and 0 being length+1 => adding new element arr:= ["A", "B", "C"] ...

@_3D_ you may want to see this thread for discussion: https://www.autohotkey.com/boards/viewtopic.php?f=37&t=67213 TY for this thread. My comment: shorthand init must be myMap:= { expressionForKey1:expressionForVal1 ,expressionForKey2: ,:expressionForVal3 } ;any omitted keys or vals must be replace...

1. If I need performance I will use C++ or C#. 2. (old AHK state) mean like a103 where array == map. 3. I make some tests about Capacity and TRUE Length not equal to Capacity. This is understandable if I need 4 items let start with 4 items and don`t need to reallocate memory. 4. I think HAS must ret...

Complete madness in arrays and maps: array:= [] loop 10 array[A_Index]:= A_Index ;Invalid Index ??? This simple code no more works. It must be something like: array:= [] loop 10 array.Push(A_Index) ;Is that a stack or ??? Question 1 : If we have control by the index what is difference between Array....

Is there some ideas Classes to be able to inherit GuiObjects / FileObjects / COMObjects ?

;Something like:

associative array => Map
no, it means no longer conflating data structures with things they are not

TY dear that spend so much time with my fallacy.

_3D_

Holy Jesus!!! It was too early to be glad. badarray := [] badarray["Key"]:= "Value" ; Invalid Index Is that mean NO MORE associative arrays in AHKv2.0 ? badarray := [] badarray.%"Key"%:= "Value" MsgBox(badarray.%"Key"%) Complete madness! badarray := map() ; SOLUTION !!! badarray["Key"]:= "Value" Msg...

Code: Select all

origPropDesc := Array.Prototype.GetOwnPropDesc('__Item')
Array.Prototype.DefineProp('__Item', {
	get: (this, index) => this.Has(index) ? %origPropDesc.Get%(this, index) : 'default', 
	set: origPropDesc.Set
})

badrray := []
MsgBox badrray[1]

THE REAL ANSWER

_3D_

TY Helgef again https://www.autohotkey.com/boards/viewtopic.php?p=289400#p289400.

Code: Select all

class myArray extends Array {
	__item[key] => this.has(key) ? base[key]: ""
}

array:= myArray.new()
MsgBox(array[1])

And it back to "bad" code.
