[Python-Dev] CPython in the web browser under Native Client (original) (raw)

I have been doing some work to extend Google's Native Client [1] to support dynamic linking [2]. For those who haven't heard of it, Native Client is a sandboxing system for running a subset of x86 code. It is proposed as a way of running native code inside web apps.

One of my aims has been to get CPython working in the web browser under Native Client without having to modify CPython.

I recently got to the point where modules from the Python standard library are importable under Native Client, including (as a demonstration) the Sqlite extension module. Sqlite also requires no modification - it builds straight from the Debian package.

I've written a simple REPL to demonstrate Python running in the browser. There are some screenshots on my blog [3]. I haven't implemented accessing the DOM from Python yet - that's another project for later. :-)
