Improving the Turtle library

[petersuter]

I used the turtle library the first time in this topic:

More shapes for turtle

Does someone know some project/lib/code snippet/whatever that permits adding new shapes for turtle? I would like to do, e.g: turtle.shape('ant') or turtle.shape('car') I know I can create new shapes or use images for that, but I want to discover if someone has done this yet, and I won’t want to use pictures now.

My suggestion for an improvement: Allow un-filled compound shape components via turtle.Shape.addcomponent(... fill=None). It seems like an artificial limitation / oversight that this is not allowed.

Also missing are:

• polylines i.e. open shapes instead of only closed polygons
• shapes containing invisible jumps / gaps / move commands
• circular arcs (as toplevel commands and as part of shapes)
• cubic Bézier curves (as toplevel commands and as part of shapes)
