lhs2TeX version 1.9 =================== We are pleased to announce the first official release of lhs2TeX, a preprocessor to generate LaTeX code from literate Haskell sources. lhs2TeX includes the following features: * Different styles to process your source file: for instance, "tt" style uses a monospaced font for the code while still allowing you to highlight keywords etc, whereas "poly" style uses proportional fonts for identifiers, handles indentation nicely, is able to replace binary operators by mathematical symbols and take care of complex horizontal alignments. * Formatting directives, which let you customize the way certain tokens in the source code should appear in the processed output. * A liberal parser that can handle most of the language extensions; you don't have to restrict yourself to Haskell 98. * Preprocessor-style conditionals that allow you to generate different versions of a document from a single source file (for instance, a paper and a presentation). * Active documents: you can use Haskell to generate parts of the document (useful for papers on Haskell). * A manual explaining all the important aspects of lhs2TeX. Changes ------- Although development on lhs2TeX has begun as early as 1997, it has never been formally released before. This is a first release that should be mostly compatible to versions that have been inofficially distributed so far. It should compile with the latest GHC versions. Two completely new modes have been added compared to previous versions: "poly" mode is designed to replace the old math mode; the restriction of having only one alignment column per code block is lifted and replaced by a generic mechanism that allows complex layouts; "newcode" is a replacement for the old "code" mode that can handle formatting directives and produces LINE pragmas in the generated code. Requirements and Download ------------------------- A source distribution that should be suitable for Unix-based environments is available from http://www.cs.uu.nl/~andres/lhs2tex/ It has been verified to build on Linux and MacOSX. You need a recent version of GHC (5.04.X or higher should do) to build lhs2TeX, and, of course, you need a TeX distribution to make use of lhs2TeX's output. The program includes a configuration that is suitable for use with LaTeX. In theory, there should be no problem to generate code for other TeX flavors, such as plainTeX or ConTeXt.
