Hi Everyone, The source code for skulpt, and my implementation of xturtle is also available on github at http://github.com/bnmnetp/skulpt. Skulpt is a Javascript implementation of the Python language that runs in the browser. I spent a good chunk of my Sabbatical a couple years ago implementing the turtle code in Javascript and then writing a wrapper to fit it into the Skulpt environment. We, at Luther College, have used the turtle code pretty extensively in the context of our interactive textbook (http://interactivepython.org) for a couple of years now. This fall we have about 25 schools around the world using the book, so I'm starting to think its pretty stable. :-) The turtle module is still missing event processing functions such as onKey, onClick, etc. But I think the vast majority of the functionality is there. If you do find something missing or have feature requests, please let me know. Brad On Wed, Sep 26, 2012 at 4:32 PM, Jurgis Pralgauskis <jurgis.pralgauskis@gmail.com> wrote:
Let's celebrate!!
not sure, how it's done under the hood, but it works http://interactivepython.org/courselib/static/thinkcspy/PythonTurtle/hellotu...
one can even code turtle online! http://interactivepython.org/courselib/static/thinkcspy/PythonTurtle/hellotu...
ps.: found a link from http://pythontutor.com/ :) and the source of magic seems to be https://github.com/bnmnetp/runestone

Hey, thats cute :)
Thanks. :-)
1) I played around, and added Turtle.circle() to actions :) in code its called called circle_forward(self, radius, extent=None) and also aliased as circle you can find it http://files.akl.lt/users/jurgis/python/crunchy/
Looks nice.
1a) seems it would be best to use canvas interface methods, which are already in graphics module (according to DRY phylosophy) or at least decine upon method naming -- which just generate code vs those that pass it to exec_js plugin
I agree... this was (and still is) just an experiment.
1b) seems, like polygons and filling also would not be a big problem https://developer.mozilla.org/en/Canvas_tutorial/Drawing_shapes#section_9 for fill you'd just jave to collect the points and then repeat them with fill() at end
Agreed.
2) and also I'd like to make it convert all actions to javacript code at once then it would be easier to implement turtel_js and graphics in other projects -- easily escaping crunchy :D
That's a good point. However, the idea was to be able to control a turtle from an interpreter, typing one instruction at a time and seeing the result.
As now for asinchronous update, the server and session must be up all the time
2a) then probably time.sleep would be also good to interface directly to js something like http://groups.google.co.in/group/phpguru/browse_thread/thread/8215dcdc2ac732...
3) how is it related to server_root/reborg js experiments?
It's not - at least not for now. The reeborg experiment is an very early prototype of an implementation of rur-ple (http://rur-ple.sourceforge.net) inside Crunchy. You can see a different version live at http://reeborg.world.googlepages.com/reeborg.html

so I'll try sth more tomorrow or in a week-time

but one more thing is I'd like to let access xturtle functionality online - one possible way could be triggering tkinter to save its canvas to ps, and then convert them with imagemagic and show via web (animated gif or static)
There's probably a better way: use the html canvas. I tried to implement a turtle module to be embedded with Crunchy (http://code.google.com/p/crunchy) - it is available as a demo experimental feature. You could use this as a starting point if you want.
