It is a first version, not well documented yet, but now you can test it with a simple "cabal install hatex".
What is HaTeX?
HaTeX consists in a set of combinators which allow you to build LaTeX code, following the LaTeX syntax in a type-safe manner. This allows you to build programs which generates LaTeX code automatically for any purpose you can figure out.
I wanted to make the release before end the proper documentation because:
1) This allow people to test the library (and hence, help me to build the documentation if any feedback comes).
2) I am too busy currently and I can't expend to HaTeX the time I'd like.
The library may need some improvements, but it worked well for my own tests.
With HaTeX, I uploaded the HaTeX-meta package. This package is needed if you want to develope a subset of the HaTeX modules, because they are automatically generated by this application. Anyway, there are notes in the API reference warning this. HaTeX-meta in Hackage:
