一种在面向对象语言中嵌入规则的预编译器的实现

传统的基于规则的工具，如OPS5，CLIPS等都是自封闭的，很难集成在用C 等面向对象语言开发的实际系统中，该文在借鉴ILOG Rules和CLIPS等工具的基础上提出一种嵌入在C 语言中的规则语言，主要研究了把该规则语言翻译到生成Rete网络推理机的C 源文件的预编译器的实现方法，该规则语言对ILOG Rules做了两点扩充，一是允许直接把C 语言嵌入在规则的条件部分和动作部分用来表达谓词测试和动作；二是增加了AND和OR两种模式成组关系，这种增强了规则表达实际问题的能力和规则与C 语言的互操作性。

A study of the implementation of the precompiler for embedding the rule-based paradigm into the objet-oriented language

Traditional rule-based tools, such as OPS5, CLIPS, etc. are standalone, so it is difficult to intgrate them into an actual system coded with the C⁺⁺ language. Based on ILOG Rules and CLIPS, a rule language embedded into the C⁺⁺ is designed and a precomplier which translates this rule language into the C⁺⁺ source is implemented in this paper. The designed rule language enhances the ability of cooperation between rule and C⁺⁺ language in two aspects: one is that the rule can be embedded directly into LHS and RHS, and the other is to allow AND and OR pattern grouping in LHS.
