软件介绍

Hammurabi 是一个 Scala 编写的规则引擎,适合实现便于阅读的内部DSL。与其他 DSL 不同的是,Hammurabi 可直接使用宿主语言编写和编译规则。

示例规则:

rule ("Person to Fred’s immediate right is wearing blue pants") let {
  val p1 = kindOf[Person] having (_.name == "Fred")
  val p2 = any(kindOf[Person])
  when {
   p2.pos equals p1.pos + 1
  } then {
    assign color "blue" to p2
  }
}
