                      Haskell Weekly News: March 20, 2006

   Greetings, and thanks for reading issue 29 of HWN, a weekly newsletter
   covering developments in the Haskell community. Each Monday, new
   editions are posted to [1]the Haskell mailing list and to [2]The
   Haskell Sequence. [3]RSS is also available.

Announcements

     * lhs2TeX version 1.11. Andres Loeh [4]announced lhs2TeX version
       1.11, a preprocessor to generate LaTeX code from literate Haskell
       sources.
       lhs2TeX includes the following features:
          + Highly customized output.
          + Liberal parser -- no restriction to Haskell 98.
          + Generate multiple versions of a program or document from a
            single source.
          + Active documents: call Haskell to generate parts of the
            document (useful for papers on Haskell).
          + A manual explaining all the important aspects of lhs2TeX.

Discussion

     * Deep Functors. Oleg Kiselyov [12]described an fmap over
       arbitrarily deep `collections': lists of maybes of maps of IOs,
       etc. -- arbitrarily nested fmappable things.

     * GHC 6.4.2. Simon Marlow [13]put out a heads up for the forthcoming
       6.4.2 release of GHC. The rough timescale is to go into release
       candidate testing in about a week, and have two weeks of release
       candidates before the final release.

     * Hexdump. Dominic Steinitz [14]mentioned a "hexdump" function he'd
       written, posing a question about where it would live in the module
       hierarchy..
