                      Haskell Weekly News: March 13, 2006

   Greetings, and thanks for reading issue 28 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

     * Alternative to Text.Regex. Chris Kuklewicz [4]announced an
       alternative to Text.Regex. While working on the [5]language
       shootout, Chris implemented a new efficient regex engine, using
       parsec. It contructs a parser from a string representation of a
       regular expression.

     * pass.net. S. Alexander Jacobson [6]launched Pass.net. Written in
       Haskell, using HAppS, Pass.net lets websites replace registration,
       confirmation mails, and multiple passwords with a single login,
       authenticating via their email domain.

Discussion

     * Non-trivial markup transformations. Further on last week's article
       on encoding markup in Haskell, Oleg Kiselyov [12]demonstrates
       non-trivial transformations of marked-up data, markup
       transformations by successive rewriting (aka, `higher-order tags')
       and the easy definition of new tags.

     * Popular libraries and tools. John Hughes [13]posted (and [14]here)
       some interesting figures on the most important libraries and
       tools, based on the results of his survey of users earlier this
       year.

     * haskell-prime fun. Just for fun, Ross Paterson [15]posted, some
       thought-provoking [16]statistics on haskell-prime traffic.

     * New collections package. Jean-Philippe Bernardy [17]hinted that
       his new collections package is almost done.

     * Is notMember not member? John Meacham [18]sparked a bit of a
       discussion on whether negated boolean functions are useful with a
       patch adding Data.Set and Data.Map.notMember.

     * Namespace games. In a similar vein, Don Stewart [19]triggered
       discussion on how to sort the hierarchical namespace, when
       proposing alternatives to the longish Text.ParserCombinators
       module name.

Darcs Corner

     * Darcs-server. Unsatisified with the current techniques for
       centralised development with darcs, Daan Leijen went ahead and
       [20]wrote darcs-server. With darcs-server you can:

          + push changes remotely via a CGI script
          + or push changes via a single SSH account that serves many
            users
          + use cryptographic verification and authorization of users for
            reading and writing
          + use gpg encryption (for CGI)
          + use non-public repositories that can only be accessed by
            authorized users.

     * darcsweb 0.15, by Alberto Bertogli, has been [21]released.
