Getting the canvas element is the least documented thing you need to do.

After that, you follow those rules: https://github.com/amber-smalltalk/amber/wiki/From-smalltalk-to-javascript-and-back

Not solved...

How can I write

var a = {
        first: function(parameter){
        }
        second: function() {
        }
}

in Amber? Please, help me to understand...

Excuse my ignorance, but isnt what Xumuk describes the javascript equivalent of defining methods for an object which should be replaced with the definition of methods in the smalltalk way?

Here is an attempt at converting the "Renderer" object from the file main.js that you attached earlier. I have not tested this though hopefully it leads you in the right direction.

the js line to create the renderer

 sys.renderer = Renderer("#viewport").

would be changed to

  sys renderer: (ArbourRenderer newWithCanvas: '#viewport' ) jsInterface

Also there is an error in mouseHandler class.

In function 

getMousePositionForEvent: event

     ......

     mousePosition := arbor Point: (event pageX - pos left) y: (event pageY - pos top).

     mousePosition := NativeFunction constructor: 'arbor.Point' value:  (event pageX - pos left)  value: (event pageY - pos top).

     ......

Thanks.

Here it must be changed to ( sys asJQuery ) attr: 'renderer' set: ( (ArbourRenderer newWithCanvas: '#viewport' ) jsInterface )

because of sys object don`t have a renderer field.

It is clear. Troubles are connected with such code:

var Renderer = function(canvas){

var that = {

init:function(system){

                                      ...

},

      

redraw:function(){

    ....

}

                       initMouseHandling:function(){

                                    .....

                       }

                       $(canvas).mousedown(handler.clicked);

                }

         return that;

}

Here is a function which I use to draw a line:

on: aCanvasId start: aStartPoint end: anEndPoint

|canvas ctx|

canvas :=  ('#',aCanvasId) asJQuery at:0.

console log:canvas.

ctx := canvas getContext: '2d'.

ctx beginPath.

ctx moveTo: (aStartPoint x) and: (aStartPoint y).

ctx lineTo: (anEndPoint x) and: (anEndPoint y).

ctx stroke.

I have some troubles with converting javascript to smalltalk. It`s hard for me, and i want to port this JS to Amber for learning..

I am currently working and learning the canvas element myself. What is the difficulty?

Getting the canvas element is the least documented thing you need to do.

After that, you follow those rules: https://github.com/amber-smalltalk/amber/wiki/From-smalltalk-to-javascript-and-back

I want to rewrite arbor.js example using Amber. It will help me to understand Amber more. Could somebody help me with it?

It is possible to convert created JS file to ST classes in Amber?
