Crunchy 1.0 has finally been released. :-)
Crunchy 1.0 is compatible with Python 2.4, 2.5, 2.6 ... and 3.1. It is also compatible with Jython 2.5 modulo some bugs when trying to work with examples containing unicode strings.
Crunchy, for those that are not familiar with it, is a one-of-a-kind application. It is an application designed to transforms otherwise static html Python tutorials into interactive session viewed within a browser. Currently Crunchy has only been fully tested with Firefox. Crunchy should work with all operating systems - it has been tested fairly extensively on Linux, Windows and Mac OS.
In more details, here's what Crunchy does:
1. It loads an existing html file (or reStructuredText file) containing some Python code; this file can reside locally, or anywhere on the web.
4. It sends the transformed file to your browser of choice (read: Firefox).
5. It establishes a communication between the browser and the Crunchy back end and wait for user interaction.
Crunchy can embed Python interpreters and code editors (and more!) within an html page, enabling a user to enter (or edit) some Python code inside a browser window, send it to the Crunchy back end for execution, and observe the result back in the browser window.
In a sense, Crunchy is a Python programming environment embedded within a browser. However, it does not require a custom format for interactivity: for html files, as long as the Python code is included in a pre-formatted element (<pre>), Crunchy will recognize it, style it, and include the appropriate interactive element.
Crunchy comes with a fairly complete tutorial and supporting documentation. It is highly configurable.
Release 1.0 is NOT the end of the road for Crunchy. Future plans include support for interactivity with languages other than Python.
