摘　　要：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ILOGRules和CLIPS等工具的基础上提出了一种嵌入在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ILOGRules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,这样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.Traditional rulebased tools, such as OPS5, CLIPS, etc. are standalone, so it is difficult to integrate 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 precompiler 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.
