使用

获取番符对应和牌点数

from mahjong_utils.point_by_han_hu import get_parent_point_by_han_hu, get_child_point_by_han_hu

# 获取亲家X番Y符的点数，返回(荣和点数, 自摸各家点数)
parent_ron, parent_tsumo = get_parent_point_by_han_hu(3, 40)
# parent_ron == 7700
# parent_tsumo == 2600

# 获取子家X番Y符的点数，返回(荣和点数, 自摸庄家点数, 自摸闲家点数)
child_ron, child_tsumo_parent, child_tsumo_child = get_child_point_by_han_hu(3, 40)
# child_ron == 5200
# child_tsumo_child == 1300
# child_tsumo_parent == 2600

指定绑定方式

默认情况下，py版本内部通过py-mini-racer调用mahjong-utils-entry的Kotlin/JS产物，其计算耗时约为JVM产物的2.1倍。

（为什么不是Kotlin/Native产物，因为实测下来Native产物的计算耗时约为JVM产物的7.6倍）

如果希望能够达到JVM产物的计算速度，可以选择切换绑定方式为调用mahjong-utils-webapi提供的HTTP接口，具体步骤如下：

  1. 确保已经安装Java (>= 11)
  2. 从Release页下载与python库版本相对应的mahjong-utils-webapi-all.jar
  3. 运行命令 java -jar mahjong-utils-webapi-all.jar（默认占用8080端口，如果需要指定端口：PORT=10021 java -jar mahjong-utils-webapi-all.jar）
  4. 启动python解释器前设置环境变量ENV_MAHJONG_UTILS_BRIDGE=http（如果需要指定端口与地址：ENV_MAHJONG_UTILS_HTTP_PORT=10021;ENV_MAHJONG_UTILS_HTTP_HOST=127.0.0.1）
