A separate svn project would be nice. I'm sure z3lab is open; it's also 
welcome under the z3 base on codespeak.

Right, that was my motivation too - I googled around for 
javascript-based templating languages but realized there wasn't really 
anything. Of course XSLT can be used this way too, but TAL is kinda neat 
too. Still, I couldn't think of much practical use for this. Perhaps in 
this AJAXy world this has changed.

Are you interested in recovering some of there Zope TAL based regex 
stuff from Sapling? I'd be happy to merge it in. ctal doesn't appear to 
have this yet. 'ctal' is a somewhat confusing name by the way, you'd 
think it was TAL implemented in C, another interesting project I've 
dabbled with on and off in the past.

We had an CVS to SVN conversion earlier this week, so sapling's source 
code is now here:


(check it out with: svn co https://infrae.com/svn/sapling/trunk sapling)

It has tests and everything. :)
