Revision history for Mahjong

See git repo for more detailed commit information.

0.1.0.0

First functional prototype.

0.1.0.1

Dependency versions reworked.

0.2.0.0

Help messages improved. Module structure refactored. Documentation begun.

0.2.0.1

Revised cabal version in attempt to fix build error on Hackage. Build works locally, suspect the problem is a quirk of Hackage build system. Added some more documentation.

0.2.0.2

Internal library now unnamed. Hoping this fixes Hackage build fail.

0.2.0.3

Added docs for yaku functions. Reworked seven pairs detection to ensure hand has 14 tiles. 9 gates now checks that the hand is closed.

0.3.0.0

Fixed error in scoring triple triplets, was previously scored as 1 han open. Implemented new backend for scoring and yaku detection via "context" based approach, defined in new Context submodule. This helps simplify function signatures for operations that need many pieces of information besides just the superficial composition of a hand.

0.3.0.1

Now only ask for dora after we know the hand is not a yakuman, as part of the mkContext function (previously handled dora in displayHandScore). Four concealed triplets now asks about concealment. It wasn't doing this before, a bug introduced by the refactor, since mkYakumanContext intentionally gets less information than mkYakuContext since generally it needs less. Now only ask for wind context if we see a wind tile in the hand. Note even a wind pair could matter - it won't affect most yaku but affects Fu. Speaking of - NOTE: Seat+Round wind pair counts as a yakuhai pair and awards 2+2=4 Fu. Some rulesets would only award 2 Fu.
