Haskell Weekly News: March 06, 2006

   Greetings, and thanks for reading issue 27 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

     * Haskell as a markup language. Oleg Kiselyov [4]writes on using
       Haskell to represent semi-structured documents and the rules of
       their processing. [5]SXML is embedded directly in Haskell, with an
       open and extensible set of `tags'. The benefit of this is of
       course in static type guarantees, such as prohibiting an H1
       element to appear in the character content of other elements.

     * hmp3 1.0. Don Stewart [6]released hmp3 version 1. hmp3 is a
       curses-based mp3 player written in Haskell, designed to be fast,
       small and stable.

Discussion

     * Library Reorganisation. Simon Marlow [17]opened up a discussion on
       library reorganisation, in the light of the oncoming Haskell'.

     * Deprecating FunctorM. Ross Paterson [18]proposes to replace
       FunctorM with Data.Traversable.

     * cabal-setup. Simon Marlow [19]posted a patch to wrap the Setup.hs
       Cabal script with a generic cabal-setup interface.

Code Watch

  * Make -split-objs work with --make
      Thu Mar  2 09:05:05 PST 2006  Simon Marlow

      This turned out to be a lot easier than I thought.  Just moving a few
      bits of -split-objs support from the build system into the compiler
      was enough.  The only thing that Cabal needs to do in order to support
      -split-objs now is to pass the names of the split objects rather than
      the monolithic ones to 'ar'.

Quotes of the Week

    [OConnor's Law]
    roconnor :: As an online discussion of static types vs dynamic types
                grows longer, the probability of mentioning heterogenous
                lists approaches 1.

    [Lemmih's Law]
    Lemmih ::   Every 18 months, compilers will make their warnings and
                error message s twice as cryptic

    Claus Reinke :: The point about overlapping instances is that they shouldn't.
