In compiler design, the substrings are referred to as lexemes and the categories are referred to as token types or just tokens. The categories are defined by patterns which are specified using regular expressions. The process of splitting up a string is sometimes called tokenization, lexical ...

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。
* If the compiler generates a YYPARSERNAME error then you have not declared * the name of the parser. The easiest way to do this is to use a name * declaration. This is placed in the declarations section of your YACC * source file and is introduced with the %name keyword. For instan...
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 ...
PTC Lex & YACC is integrated into Microsoft Visual Studio and VS.NET with the PTC Lex & YACC MSVC Add-in allowing you to build and manipulate your Lex and YACC source files within the VC++ IDE. Typical Uses PTC Lex & YACC can be used to quickly and easily build: • Compiler front...
