Welcome to issue 202 of the HWN, a newsletter covering developments in the Haskell community. This release covers the week of September 25 to October 1, 2011. New and Updated Projects * ParserFunction (Enzo Fabrizio; 0.0.5) Provides utilities for parsing and evaluating mathematical expressions. [1] http://goo.gl/xNOe1 * flexiwrap (Iain Alexander; 0.1.0) Also updates to related packages: data-type, function-combine, and flexiwrap-smallcheck. [2] http://goo.gl/dN0ew * crypto-api-tests (Thomas DuBuisson) These tests have been split out into their own package. Tests now use the test-framework package. [3] http://goo.gl/7kUIV * hledger (Simon Michael; 0.16) Stability/bugfix/polish release. [4] http://goo.gl/hW085 * GA (Kenneth Hoste; 1.0) Major version bump to this genetic algorithms package. [5] http://goo.gl/NoAl4 Quotes of the Week * glguy: lazy evaluation is best 50% of time because there are 2 cases, the cases where it is the best and the cases where it is not the best * Cale: Computing lengths is admitting defeat * syntaxfree: Many people think the core ideas behind Haskell [snip] In the Deep Complex Universe some Gnomes were having Tangling problems. Wadler & friends solved their problems and as a reward the Tangled Gnomes gave them the Secret of Haskell * monochrom: How do I extract the IO out of IO String?
