SVGKit in the MochiKit Interpreter

This is the interpreter from MochiKit with the SVGKit libraries included. Type some code into the text input and press enter to see the results. As an example, the following creates a square, displays the SVG, then adds a circle:

svg = new SVGKit(100,100)
rect = svg.RECT({x:10, y:10, width:50, height:50, fill:'red'})
svg.append(rect)
writeln(svg.svgElement)
circ = svg.CIRCLE({cx:60, cy:60, r:20, fill:'blue', 'fill-opacity':0.5})
svg.append(circ)

• To write multi-line code snippets, use the lower text area and press ctrl-enter or cmd-enter to submit.
• function name() {} syntax might not end up in window scope, so use name = function () {} syntax instead
• If you want to stuff something into the output window other than the repr(...) of the expression result, use the writeln(...) function. It accepts anything that MochiKit.DOM does, so you can even put styled stuff in there!
• Use clear() to clear the interpreter window.
• Up and down arrow keys work as a rudimentary history
• _ is the value of the last expression that was not undefined, last_exc is the value of the last unhandled exception.
