这个函数叫做解析器(parser),它调用用户提供的低层输入例程(词法分析器(analyzer))来从输入流中选取基本项目(叫做记号(token))。依据叫做文法规则的输入结构规则来组织这些记号;在识别了这些规则中的某一个的时候,接着调用为这个规则提供的叫做动作的用户代码;动作有能力返回值并使用其他动作的值。 Yacc 是用 C[...

Combined with the rapid development cycle of Java, automatic parser generation provides a tool for compiler design that is hard to beat.Jack (rhymes with yacc) is a parser generator, in the spirit of PCCTS, that Sun has released for free to the Java programming community. Jack is an ...
This is similar to the problems encountered trying to debug a compiler lexical analyzer and parser written with LEX and YACC. In these applications, debugging is straightforward when the thread of control is in the user-defined action routines. Object-oriented application frameworks BookSim is written...
Rule 1 implies that reductions are deferred in favor of shifts when there is a choice. Rule 2 gives the user rather crude control over the behavior of the parser in this situation, butreduce-reduceconflicts should be avoided when possible. ...

YACC(Yet Another Compiler Compiler) 是1974年在Unix下设计出来的一个优秀的计算机语法分析工具。LEX是相应的词法分析工具。在Linux下,也有YACC/LEX的实现版本及相关资料。通过这套工具,可以在只编写出计算机语言的语法后,就可以生成自底向上的语法分析程序(词法分析类似),可以大大加快计算机语言的实现速度。
