Porting StringTemplate isn't exactly easy, esp. since it uses ANTLR  
v2. My attempts
to do an Obj-C port haven't been exactly successful, mainly because  
ANTLR v3 threw
up parsing ST :(

I don't think that parsing ST by hand is a viable option, since it is  
a bit involved
at times. I certainly wouldn't attempt it unless I was desperate...
In the long run, though, v3 should be able to handle ST easily and  
that would make
it a lot easier (even if you'd need to write a new v3 target).

As to the ECMAScript target, I'm not sure whether the current engines  
are really fit to
do recursive descent parsing in. All the engines I have seen have  
some real issues in
regard to memory, ie. tend to be slow molasses (but I admit it would  
a cool thing to have
now and then).
