How API-stable is Monkey2 for the future?

What I mean is:
At first exists BlitzBasic,BlitzPlus,Blitz3D.
Then comes the platformindependent BlitzMax.
Then comes Monkey, which supportes besides the native desktop platforms HTML5, Android, etc.
And now we have Monkey2. Which have what advantages over the first Monkey?
And for every new Programming language / dialect it have to be new written (or ported over ?) the libraries for GUI, 2D, 3D, etc.

So, how API stable is Monkey2?
Or will be soon created a Monkey3?

At the moment Monkey2 looks a lot of different to the C-like languages and to VisualBasic.
I know ANSI-C, Java, QBasic, VisualBasic and so on. And Monkey 2 looks a lot of different.

What is needed for the IDE I have written in the Ted2Go Issue-section:
https://github.com/engor/Ted2Go/issues/158
https://github.com/engor/Ted2Go/issues/159

At first I am looking, how a XML to Monkey-converter would be looking like.

<Control type="Window" name="myWindow">
  <Control type="Bytton" name="MyButton" text="My Button" />
</Control>

</Control>

would be look like

#Import "<std>"
#Import "<mojo>"
#Import "<mojox>"

Using std..
Using mojo..
Using mojox..

Class MyWindow Extends Window
  Method New()
    Local MyButton := New PushButton("My Button")
    ContentView = MyButton
  End
End

Function Main()
  New AppInstance
  New MyWindow
  App.Run()
End

#Import "<std>"

#Import "<mojo>"

#Import "<mojox>"

Using std..

Using mojo..

Using mojox..

Class MyWindow Extends Window

Method New()

Local MyButton := New PushButton("My Button")

ContentView = MyButton

End

Function Main()

New AppInstance

New MyWindow

App.Run()

End

Interesting that there don’t exista a

Add(MyButton)

1	Add(MyButton)

this.Add(MyButton)

1	this.Add(MyButton)

but there exists a

AddChildView(MyButton)

1	AddChildView(MyButton)

without effect.
and what is the “this” (in Java) or “Me” (in VisualBasic) in Monkey 2 ?

And how can I set the size of the window? And how can I make it resizable?

Mark Sibly (the creator) has stated that he will not create a Monkey3 and will stick with Monkey2.
The biggest problem now is Apple deprecating OpenGL. But porting mojo to vulkan is on the todo list so there’s hope!

Which have what advantages over the first Monkey?

Mark has moved to monkey2 mainly to avoid the hassle of a multi language transcompiler (Monkey1 was transpiling to javascript,c++ & java). It meant a lot of work for each language change. Monkey2 is only transpiling to c++, using the JNI for Android and emscriptem for javascript. So changes are mostly made once for all.
Monkey2 thus has more advanced programming features available such as firstclass functions, mutlithread, incremental garbage collector, class extensions, lambdas, etc..
It is a bit stricter with types too, which helps seeking compilation errors.
If you want fast html5 developpement you might prefer Monkey1 as it has a very fast javascript transcompiler and outputs very nice html5/javascript code.

Monkey2 is clearly lacking of a good beginner tutorial. You can find a lot of simple examples on pakz’s examples pack but there is no real tutorial beginning from 0.

A GUI editor would be awesome!

and what is the “this” (in Java) or “Me” (in VisualBasic) in Monkey 2 ?

Self

You can call a field/method inside a class without Self if there is no ambiguity.

And how can I set the size of the window? And how can I make it resizable?

To make it resizable use the WindowFlags.Resizable when calling New. To set the initial size, do it via New too. (as shown in the example below)

Here is a short example taken from modules/mojox/test folder. It’s the folder where you’ll find simple examples for mojox. Slightly modified to show window size when clicking. You might be confused by the Lambda, it’s just like a function, you could declare the action in a function or method.
Note that mojox is not that easy to get compared to mojo. And if you plan to make a game it is not really advised to use mojox, you should prefer a custom GUI system like the one offered in pyro for example. mojox has been created to create Ted2 initially and only a few people really use mojox, to write their own editors.

#import "<std>"
#import "<mojo>"
#import "<mojox>"

Using std..
Using mojo..
Using mojox..

Class MyWindow Extends Window
	Field n:=0
	Method New()
		Super.New( "Button Demo",640,480,WindowFlags.Resizable )

		Local label:=New Label( "Idle" )
		
		Local button:=New Button( "Click ME!" )
		
		button.Clicked=Lambda()
			n+=1
			label.Text="Clicked #"+n+" window size:"+Width+","+Height
		End
		
		Local dockingView:=New DockingView
		dockingView.AddView( label,"top" )
		dockingView.ContentView=button

		ContentView=dockingView
	End
	
End

Function Main()

	New AppInstance
	
	New MyWindow
	
	App.Run()
End

#import "<std>"

#import "<mojo>"

#import "<mojox>"

Using std..

Thanks for your help.

I think Monkey2 is for beginners, so it needs an easy start for beginners.
I have in the meantime looked at the calculator example, but your example is a lot easier.
I have a little bit played with it.

A xml description file could look like

<Control type="Window" name="MyWindow" width="640" heigh="480">
  <Property name="WindowFlags" value="Resizable" />
  <Control type="DockingView" name="dockingView">
    <Control type="Label" name="label" text="Idle"/>
    <Control type="Button" name="button" text="Click ME!"/>
  </Control>
</Control>

</Control>

That could be used as intermediate langaue for an GUI-designer. Or as additional language like Microsoft doing it with XAML for its WindowsPresentationFoundation.

This XML-code is only a how it could look like, but currently ignored the

dockingView=New DockingView
dockingView.AddView( label,”top” )
dockingView.ContentView=button

That xml-file should then generate automatically (or compiled to) the file ButtonDemo_ui.monkey2

#import "<std>"
#import "<mojo>"
#import "<mojox>"
 
Using std..
Using mojo..
Using mojox..
 
Class MyWindow_ui Extends Window
	Field label:Label
	Field button:Button
	Field dockingView:DockingView
	
	Method New()
		Super.New( "Button Demo",640,480,WindowFlags.Resizable )
 
		label=New Label( "Idle" )
		
		button=New Button( "Click ME!" )
		
		button.Clicked=Lambda()
			button_Clicked()
		End
		
		dockingView=New DockingView
		dockingView.AddView( label,"top" )
		dockingView.ContentView=button
 
		ContentView=dockingView
	End
	
	Method button_Clicked() Virtual
	End
	
End

#import "<std>"

#import "<mojo>"

#import "<mojox>"

Using std..

Using mojo..

Using mojox..

Class MyWindow_ui Extends Window

Field label:Label

Field button:Button

Field dockingView:DockingView

Method New()

Super.New( "Button Demo",640,480,WindowFlags.Resizable )

label=New Label( "Idle" )

button=New Button( "Click ME!" )

button.Clicked=Lambda()

button_Clicked()

End

dockingView=New DockingView

dockingView.AddView( label,"top" )

dockingView.ContentView=button

ContentView=dockingView

End

Method button_Clicked() Virtual

End

And the written code would then be in the file ButtonDemo.monkey2

#import "ButtonDemo_ui"
 
Class MyWindow Extends MyWindow_ui
	Field n:=0
	Method button_Clicked() Override
		n+=1
		label.Text="Clicked #"+n+" window size:"+Width+","+Height
	End
End

Function Main()

	New AppInstance
	
	New MyWindow
	
	App.Run()
End

#import "ButtonDemo_ui"

Class MyWindow Extends MyWindow_ui

Field n:=0

Method button_Clicked() Override

n+=1

label.Text="Clicked #"+n+" window size:"+Width+","+Height

End

Function Main()

New AppInstance

New MyWindow

App.Run()

End
