Flex词法/语法分析器源码

一个外国人写的词法分析程序，大家可以参考一下，不过代码太多了！ 有点难-a foreigner writing lexical analysis procedures, we can take a look, but too many of code! Hard

基于libboost_regex的正则表达式测试程序，可用于入门者的参考代码。-Libboost_regex regular expression-based test procedure can be used for a reference code for beginners.

Fenris是一个检测并把高层次的语言结构做成文档的多功能故障检测器、调试器、代码分析工具。它能回复符号，把程序执行流绘成图，检查内部运行情况，恢复符号表，并处理反调试保护。它有一个命令行接口和一个类似SoftICE的GUI与Web前端-Fenris is a detection and high-level language structure made of multifunctional document fault detection, debugging, code analysis tools. It can restore symbols, compose program execution flow map, check their internal operations, restoration of the symbol table, and to deal with anti-debugging protection. It is a command line interface and a similar SoftICE with the GUI front-end Web

由于Ogre自带的模型观察器无法处理中文名，和查看从天龙八部中导出的mesh和骨骼动画，所以他写了一个小工具。过程中重编译了Ogre的源码以便其支持中文资源名和处理天龙八部的模型资源。-model editor

一个带界面的词法分析器～～界面比较简练友好，适合初学者使用-An interface with a lexical analyzer ~ ~ more concise and friendly interface, suitable for beginners to use ~~~~~

拿出这个程序来主要是因为原文中只有一个LEX程序,- Puts out this procedure to come mainly is because in the original text only has a LEX procedure,

输入一个正则表达式，可以使用： 小写字母或数字，表示终结符；*，闭包；+，并集；~，补集；E，空串；O，空集 然后程序将生成 相应的NFA，以及化简之后的DFA，最后再输入一个字符串，程序判断它是否满足该正则表达式-input is a regular expression, you can use : lowercase letters or numbers, said Fu end;* Closure; , And set; To complement the set; E, empty string; O, empty set procedures will then generate the corresponding NFA, and the simplification of the DFA after finally lose into a string, procedures judgment whether it is to meet the regular expression

编译原理的一个小实例 YACC(Yet Another Compiler-Compiler)是LALR(1)分析器的自动生成工具，它的第一版于70年代初发表，是美国贝尔实验室的软件产品（作者为S.C.Johnson） YACC将一前后文无关文法转换为一LALR(1)分析表,并提供使用该分析表进行语法分析的总控程序yyparse().-compiler principles of a small example of YACC (Yet Another Compiler- Compiler) is LALR (1) the automatic generation analyzer tool, its first edition in the early 1970s, was published in the United States Bell Labs software products (the author S. C. Johnson) will be a before and after YACC grammar unrelated to the text converted to a LALR (1) Analysis Table, and provide analysis of the use of the table for syntax analysis of the total control procedures yyparse ().

PL0_CPP C++版本的PL0 语言的编译器，实现了编译器的一般功能-PL0_CPP PL0 version of the C language compiler, a compiler to achieve the general functions
