Readme for riichi-scoring-0.4.1.0

[back to package description]

This package provides a CLI tool with commands for determining the yaku, fu, and score of a hand in Riichi Mahjong. It can also determine the waits of a partial hand.

The CLI tool supplied is the riichi command. Help information is as follows:

Command riichi:
    Possible subcommands: yaku, waits, score (default = yaku)

Usage:
    riichi <subcommand> "<hand>"

    "yaku" and "score" subcommands expect a full hand.
    "waits" subcommand expects a hand that is tenpai.

    Example hands include:
        "123p 234m 444p rrrr NN"
        "344556s 444p 222m EE"
        "19p 19s 19m 1p NESWrgw"

    In detail, numeric tiles are denoted (1-9) + (m, p, or s),
    Winds are denoted N, E, S, W, and Dragons are r, w, g.
    A 0 can be used to denote a red five.
    Numeric tiles of the same suit, and honour tiles, can be 
    grouped as seen in the examples (but needn't be).

    In scoring a hand, dora and seat/round wind must be supplied,
    also in this format.

Internal libraries are also exposed.
