Class Paper2 has a newPath method which gives back an instance of a JSProxyObject. However when I send a message to that object I get an error *too much recursion.

!Paper2 class methodsFor: 'not yet classified'!

newPath
<return (new paper.Path());>
!

main
| canvas aPath |
   canvas := document getElementById: 'myCanvas'.

   "Create an empty project and a view for the canvas:" 
    paper setup: canvas.

    aPath := self newPath.

"Give the stroke a color"
aPath inspect.
aPath strokeColor: 'red'.
!

Note Class Paper1 is a JavaScript only solution which works. The aim of class Paper2 is to have it translated into Smalltalk.

In #2 the installation instructions were updated. Now bower.json has to reflect this.

Is the way used to include the in index.html correct?

 <script type='text/javascript'>
  require.config({ paths: {
    'paper': 'bower_components/paper/dist'
  }});
  require([
           'bower_components/paper/dist/paper-full.js'
          ], function( Paper ){ 
                window.Paper=Paper;
             }
  );
</script>

In addition I wonder why the Paper variable starts with uppercase whereas in the code Paper1>>main it is referenced with lowercase paper

No manual editing of bower.json

You can do it without manually editing bower.json. Just run

      bower install paper --save

You should go the standard way.
Standard way is to install by bower with --save, not editing bower.json by hand. It then should produce good pattern.

The usual pattern is something like "~0.5.3-alpha" which says "any from the same family as 0.5.3-alpha is", that is, 0.5.whatever.

The comma after "physicsjs": "~0.6.0" needs to be removed. bower install currently fails due to that typo
