Wow. I'm impressed. On Sun, Jun 14, 2009 at 9:09 AM, Mark Seaborn wrote:

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. :-)

Hey Mark,

Really glad to see that you carried on with this -- great work!! I guess the elders will simply say that it's history repeating itself, but Grails 2.0 is looking promising! We can finally give that upstart Javascript a run for its money (despite ES5 looking nice...) -- not to mention Google Wave/Opera Unite/etc. Now, the real blocker is accessing the DOM from Python. I haven't looked into the source code deeply, but perhaps Kroll could be of help: * http://github.com/jhaynie/kroll/tree/master I was able to do the following with Titanium Desktop (which uses it) to access the DOM from Python: <script type="text/python"> def hello(s): document.getElementById('foo').innerHTML = s </script> <div> Hello <div id="foo">World</div></div> <script>hello("tav")</script> More relevant links: * http://www.appcelerator.com/ * http://github.com/appcelerator/ Anyways, I'm sure others might have a better idea of integrating Python and the DOM.
