Thanks for the gnuplot stuff. I intend to try that out. Perhaps sooner than later. As for lhs2tex, since no windows installer is provided, it might be a bit trickier and my time is very limited. Also after reviewing the manual it seems to still be focused on literate programming more than active documents. Active document support in general seems to be hard to find in the open source world. I have Maple, but their new document mode is not very useful for producing quality typeset mathematics and figures. My best results have been using either programmatically generated latex macros for inclusion into a document, or to use search and replace on text based document formats (e.g. .rtf or I suppose .pdf) -- View this message in context: http://www.nabble.com/Troubles-with-FFI-t1611744.html#a4421523 Sent from the Haskell - Haskell-Cafe forum at Nabble.com.
