Assuming you have the latest (version 0.2) alpha release of the new Crunchy, edit the file vlam.py, replacing "interpreter" by "editor" at lines 108 and 109. Then, launch Crunchy and click on the "tests" link. On the following page, click on the "Loading arbitrary tutorials" link. Then, in the box for loading remote tutorials, enter the address of the Python cookbook (http://aspn.activestate.com/ASPN/Python/Cookbook/).
The formatting will be off, but you can select your favorite recipe. When you do this, you can edit the code and execute it right on the page. Often, all you need to do is to replace
__name__ == "__main__"by
Trueand you are ready to try the examples, modifying them at will.
In the near future, Crunchy will provide an easy way to select which interactive element (Python interpreter or editor) is to be inserted by default, without having to edit the code by hand.
