编译原理中的语法分析器,处理文档中有所要的解析的代码.

c编译器实现，利用lex yacc写的简单编译器-achieved using lex generates write a simple compiler

用于中文分词的切分词典,还有词性标注,以这个词典数据库为基础建立文本分类,文本检索或文本过滤可以节省很多时间.很全,强烈推荐!-for the Chinese word segmentation Dictionary, and tagging to the dictionary database based text classification, text retrieval or text filtering can save a lot of time. All very strongly recommended!

很详细的PL0编译演示程序,学习编译的极品! -very detailed PL0 compiler Demonstration Program, the study compiled Acura!

c++单元测试框架，CppUnit 基于JUnit-c unit test framework, based on the JUnit CppUnit

词法分析程序 程序当前目录里自己建立一个文本文档，取名为infile.txt,所有需要分析的程序都写在此文本文档里，程序的结尾以"@"标志符结束。运行词法分析程序，程序结果输出到文件名为outfile.txt的文件中,此文件为自动生成。-lexical analysis Procedure current directory to establish his own version of a document, named infile.txt, all need to analyze the procedures are written in the article of this document, at the end of procedures to "@" signs Fu end. Running lexical analysis procedure, the results of the proceedings output to a file called outfile.txt document, this document is generated automatically.

该文件主要是一个编译原理函数语言绘图器，可以利用起来翻译图象代码-the document is mainly a function of compiler theory language mapping device that can use up images code translation

压缩文法等价变换，输入一个文法，可以对其进行等价变换，很方便-compression grammar equivalent transformation, importation of a grammar can transform its equivalent, is a convenient

C-MINUS编译器，一个很不错的编译原理实践成果-C-MINUS compiler, a very good practice to compile the results of the principle

用java实现的简单编译器，希望对大家有用-Achieved with a simple java compiler, and hope for all of us

LL(1)文法使用的是确定的自顶向下的分析技术。LL(1)的含义是：第一个L表明自顶向下分析是从左向右扫描输入串，第2个L表明分析过程中将使用最左推导，1表明只需向右看一个符号便可决定如何推导，即选择哪个产生式(规则)进行推导。 LL(1)文法的判别需要依次计算FIRST集、FOLLOW集和SELLECT集,然后判断是否为LL(1)文法,最后再进行句子分析。 -LL (1) grammar using a set top-down analysis techniques. LL (1) the meaning is: the first one L shows a top-down analysis is a scan input string from left to right, the first two L shows the analysis process will be the most left-derivation, one that will be just right to see a sign can decide how to derive, choose what Production (rules) for derivation. LL (1) grammar, followed by calculation of the discriminant needs FIRST sets, FOLLOW sets and SELLECT set, and then determine whether to LL (1) grammar, the last sentence further analysis.
