编译原理(词法分析)

c语言编译器源代码，small c for z80源代码，对学习c语言本质很有好处。-c language compiler source code, small c for z80 source code, the nature of learning c language is very good.

你可以任意输入合法文法，给定任意的句子，将会分析出这个句子是不是文法的的句子-You can enter any legal grammar, given any sentence, it will analyze the sentence is not grammatical sentences! !

加速度信息采集程序.主要是通过界面显示物体移动的信息采集。-Accelecer information program very useful

一个程序，用于判定给定的文法是否为算符优先文法。 实现了：1．文法的机内表示；2. FIRSTVT集和LASTVT集的计算； 3. 算符优先关系矩阵的构造。-a procedure for the determination of grammar to whether the operator priority to grammar. Realized : 1. Grammar said the machines; 2. LASTVT FIRSTVT sets and set computing; 3. Operator precedence relations of the matrix structure.

从一个开源软件中摘取的正则表达式模块，是学习正则表达式、编译原理的好东西。-From an open-source software in the removal of the regular expression module, is to learn regular expressions, compile the principle of good things.

构造接受语言{{}}的一台自动机，对于任意输入的一个字符串，模拟其运行过程，判断字符串是否接受。-structure acceptable language (()) of an automatic machine for the indiscriminate importation of a string, its process simulation, the judge whether to accept the string.

语法分析的功能： 语法分析是编译过程的核心部分，它的主要任务是按照和程序语言的语法规则，从由词法分析输出的源程序符号串中识别出各类语法分析成分，同时进行语法检查，为语义分析和代码生成作准备。 有报告-Parsing functions: syntax analysis is the core of the compiler process, its main tasks and procedures in accordance with the grammatical rules of language, from the output by the lexical analysis of source symbols to identify all types of string parsing components, at the same time syntax checker for semantic analysis and code generation to make preparations. There are reports

djgpp源码，含有gcc2.9编译器，汇编工具，debug工具等-Source coded of djgpp , it includes the gcc2.9 compiler, ASM tools, the debug tools etc.

生成C++的词法/语法分析的Flex语法分析器 -Flex syntactic and phrase parser which can produce C++ code

语法分析器，实现pascal语言的分析，对源程序从左到右进行扫描，对组成源程序的字符串拼接成为单词；并把其并把其转换成属性字输出,并管理符号表，处理词法错误。-Parser to realize pascal language analysis, source code is scanned from left to right, to the composition of a string of source code splicing into words and its properties and to convert it into a word output, and manage the symbol table, dealing with lexical错误.
