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。
LEX is a program generator designed for lexical processing of character input/output stream. Anything from simple text search program that looks for pattern in its input-output file to aC compilerthat transforms a program into optimized code. ...
The data structures need for parsing is defined in a header file named ast.h There are 5 structures namely Statement, Arg, Exp, Memory_arg, Immediate to keep the different elements of a statement in different field so that they can be translated in the code generator.For some data ...
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...

This direct approach does not often pop up in compiler classes, unlike the Thompson algorithm, which is easier to understand. Therefore, I want to discuss roughly how lex's automata can be implemented. The discussion is comprised of two parts. The first part talks about the data structure of...
