I checked the dojo source code, and found that line2pc is used exactly nowhere; the check for that global is just a poke in the dark to see if the interpreter is really spidermonkey. I commented out the throw the dojo source, and everything seems to be working swimmingly, so far at least. Go ahead and post these comments, if you like -- the dojo/doh/smjs combination looks to be really handy, and the info might be of use to someone. Atul, scratch that.

I've picked up your version of python-spidermonkey from Google Code, as part of the test rig for a citation formatter for use in Zotero (code repository under the name link to this post). This is great stuff, and it's been _extremely_ helpful to the project. I've run into a little snag, though, and I'd like to fish for some advice. My code base currently has tests run by the DOH test harness from Dojo. I thought I would just carry the test suite across to spidermonkey, so I built an sm version of dojo, and gave it a whirl. It fails with the following error: JavaScript error at line 15: "attempt to use SpiderMonkey host environment when no 'line2pc' global": This appears to be a SpiderMonkey native function that's available from the command line. So I'm wondering ... is there some means of waking up this side of the interpreter in python-spidermonkey, or should I drop the idea of testing on the JS side of the bridge, and test the string output in Python instead? Any advice or thoughts would be very welcome. Hi, Atul.

Like you describe, I've been looking for a way to avoid duplicating logic in javascript and in my webserver. AppJet is one interesting possibility (just a javascript webserver) but I'd prefer Django for general interoperability. I'll check out pythonspidermonkey. This looks pretty neat.

It's for embedded code that will only run inside Mozilla, so in contrast to python-spidermonkey, you can't just "import pydom" from ordinary CPython code. Is PyDOM included with Firefox 3?

I'd love to see Python be available in extensions, e.g. for Thunderbird. Note however that there are plans for ChromeBug, which I look forward to as well. V. cool.

I added a link to the MDC PyXPCOM and PyDOM pages. The OLPC folk are trying to bridge their XULRunner Browse component with Python programming (Google OLPC PyXPCOM and see http://wiki.laptop.org/go/JS-Python), maybe your project will help.
