Now what I would like to do, is to create a mathematical expression in Haskell (using e.g. an expression tree), which can be evaluated in Haskell, and be converted to something pretty-math-printable (MathML, PS, PDF, LaTex, whatever).
There is the LaTeX preprocessor lhs2TeX which can typeset Haskell expressions in LaTeX's math mode. However I find the conversion not very well designed (e.g. the handling of parentheses).
There was a program "TeX Haskell mode" by Manuel Chakravarty, also lambdaTeX, etc., but if I understand well, this IS NOT what Peter V. wants. He wants a specific pretty-printer *in Haskell*. This was most probably a subject of many students' exercices... Jerzy Karczmarczuk
