Haskell Weekly News: January 3, 2005
Greetings, and thanks for reading the 18th issue of HWN, a
weekly newsletter for the Haskell community. Each Monday, new
editions will be posted (as text) to
Haskell mailing list and (as HTML) to
The Haskell Sequence.
This issue brings a change to the Haskell Weekly News as Don Stewart
takes over from John Goerzen as editor. Thanks goes to John for his
excellent work on the first 17 editions!
- Process library. Bulat Ziganshin announced a new
library abstracting over some of the process and concurrency
functions in the standard libraries, using ideas from Unix
- Djinn. Lennart Augustsson released
Djinn, a theorem prover/coding wizard, that generates
Haskell code from a given type. A lambdabot plugin for Djinn was
also written, for use in #haskell.
- Ranged Sets. Paul Johnson released a ranged
sets library 0.0.1 and 0.0.2.
Ranged sets allow programming with sets of values that are
described by a list of ranges. A value is a
member of the set if it lies within one of the ranges.
- Hmp3. Don Stewart announced
a stable release of hmp3, an curses-based mp3 player written in
Haskell. Portability has improved, and binaries are available
for 5 architectures.
- HSQL. Krasimir Angelov released HSQL
1.7. New features include a driver for Oracle.
- HDBC. John Goerzen announced the 0.5.0, 0.6.0
releases of Haskell Database Connectivity library. Patterned
after Perl's DBI, it includes an Sqlite3 and a
- Shellac. Robert Dockins released
Shellac, a framework for building read-eval-print style shells.
This should ease the burden of binding readline-style
interactive shells in Haskell.
- Lambda Shell. Robert Dockins also released v0.1 of Lambda
Shell, a shell environment for evaluating terms of the pure,
untyped lambda calculus. A lambdabot interface for use in #haskell
- Shaskell. David Mercer announced
version 0.21a of Shaskell, a SHA2 library for sha256 and
sha512 hashes, written in pure Haskell.
- hdbc-missingh. John Goerzen announced
the initial release of HDBC-MissingH, a library to add database
features to MissingH, allowing the use of a SQL database as
storage for a simple DBM-like key/value interface.
Making Haskell More Open. Simon Peyton-Jones reinitiated a
on how to make Haskell more open, and in particular how to make it
easier for Haskell users to contribute.
- The Unboxed Kind. Ashley Yakeley asked
about creating type variables with unboxed kind. This lead to an
interesting discussion about the difficulties that result, including
the problems of polymorphic functions over unboxed values.
Fptools in Darcs. John Goerzen has set
up live darcs mirrors of fptools, ready for testing. With
over 13,000 patches in fptools, you'll want to use
- Darcs 1.0.5. A stable release of Darcs
1.0.5 was made. This release includes fixes for Windows, as
well as some new features.
- darcsweb. Alberto Bertogli announced
darcsweb 0.13, a rather lovely web interface to darcs repositories.
