HStringTemplate is a general purpose templating system, geared
especially towards HTML and based on Terrence Parr’s Java library.
On Hackage at: http://hackage.haskell.org/cgi-bin/hackage-scripts/
Development version at: darcs get http://code.haskell.org/
Haddocks at: http://code.haskell.org/HStringTemplate/dist/doc/html/
Additional documentation on the grammar at: http://www.antlr.org/wiki/
display/ST/StringTemplate+3.1+Documentation as well as in some posts
Lots of cleanup, lots of additions, hopefully this is an extremely
usable release. Still no group or interface files, but I suspect that
those are mainly useful for code-generation, which seems like
something Haskell programmers would want to use something other than
a templating system for in any case.
On to the good stuff:
* Now on hackage!
* Generics. Not one but two types. One set of simple bindings
for the standard Data class, and one for syb-with-class. (Alex
Drummond’s RJson library, which is really cool, was very helpful in
figuring out how to do this).
* A withContext method that turns any set of name-value bindings
into the context for a StringTemplate. Along with the syb-with-class
bindings, this should make for relatively seamless interoperability
* Lots of other additional bindings for working with standard
time formats, numeric types, etc.
* Encoders. A standard mechanism for HTML-escaping strings (or
happens uniformly and B) ensures it happens no more than once.
* Improved pretty printing support, eliminating corner-cases
where wrapping did not occur.
* Creation of directory groups is now done properly in the IO
monad, with caching functionality moved to the scarily-named
* 80% Top-Level testing coverage in the base. (And more to come,
but I only have so much time).
And of course, patches and feedback always welcome.
