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 the Haskell mailing list and to The Haskell Sequence. RSS is also available.
lhs2TeX version 1.11. Andres Loeh announced lhs2TeX version 1.11, a preprocessor to generate LaTeX code from literate Haskell sources.
lhs2TeX includes the following features:
Deep Functors. Oleg Kiselyov 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 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 mentioned a "hexdump" function he'd written, posing a question about where it would live in the module hierarchy..
ihope :: My factorial function uses GADTs.
