Tornado: FriendFeed's non-blocking Python web server is now open source

The templating system they developed looks pretty sweet http://github.com/facebook/tornado/blob/master/tornado/templ....

Just played around with it a bit and it's basically what I want:

1) Simple and clear syntax (e.g. they use 'end' not endfor, endblock, etc)

2) Assign template variables to anything (including functions)

3) Don't over-restrict the author (e.g. they allow list comprehensions in if tags)

4) Block and extends statements.

Error handling seems to be a little clearer than other template languages though still not great:

Clearly it's not going to be for everyone but after slogging around with Mako for the last year (<%namespace:def /> tags anyone?) this is like a breath of fresh air.

Thanks! Yah, the reason we rolled our own is because all the rest were so restrictive to authors. We didn't want a template system telling us what we should and shouldn't do in templates, so ours was a very thin layer on top of what basically translates directly to Python. It is actually one of my favorite parts of the system.
