Post-Hackathon Report

This page is for listing what was done during the Hackathon. Please add a short description of what you worked on, with links to relevant blog posts, hackage packages, commits, etc.

fclabels 1.0 release

New release of the fclabels package. The new package has a lot of code and documentation cleanups, support for partial labels in the case of multi-constructor datatypes and is about 20x as fast for setting and modifying as the previous version. Thanks everyone for helping me out!

GHC and base library improvements

  • Add unchecked left and right bit shifts: The Data.Bits.shift method uses a branch to check if the shift amount is larger than the word size and returns 0 in these cases. This extra safety makes performance worse in bit twiddling code.
  • Discussed unpacking of enums in GHC (not yet implemented).

Darcs

New contributors:

  • use red text to report when we have a conflict (issue1681,[1], Jeff Foster)
  • support 'since' in English dates parser
  • filter SSH output (issue845, Jeff Foster and Sebastien K)
  • support arbitrary darcs command in darcs-test (Alexander N)
  • output ISO dates in darcs changes? (issue140, Alexander N, may be not a good idea)
