Osprey源代码,绝对值得一看,Osprey权威资源代码-Osprey source code is absolutely worth a visit, Osprey authoritative source code

flex code，compiler theory curriculum design, the C write PL / 0 compiler, a detailed documentation and code -flex code, compiler theory curriculum design, the C write PL/0 compiler, a detailed documentation and code

词法分析器 可以识别c++的源码,自动生成词法分析表, 在分析结束后会指出源代码中可能的错误 待分析的源代码要以 *源代码.txt的格式保存-Lexical analyzer can identify c++ The source, automatically generate lexical analysis table, after the end of the analysis will be pointed out that the source code may be an error to be analyzed the source code to source code*. Txt format save

简单的词法扫描器，可以分析各种简单的C原文件-simple lexical scanner, a simple analysis of the original documents C

词法分析程序，很初级的，我们刚刚开编译原理- Lexical analyaer, very primary, we just opened the translation principle

按递归下降方式设计其编译程序，生成PL/0栈式指令代码，然后解释执行。用(a=1)+2*(b=3+4*5)/2+2*a*b-(a=a+5)/ (c=2) 测试-dropped by recursive approach to design their own compiler, generating PL/0 Stack-code instructions, and then the interpretation and implementation. Using (a = 1) 2* (b = 3 4* 5)/2* a* b- (a = 5 a)/(c = 2) Testing

输入已经消除左递归的以及提取公共左因子的LL(1)文法，再输入相应的表达式，若分析成功，则在递归输出过程中输出"acc",若不成功，则有相应的报错以及位置指名。注意，要把同一个非终结符的产生式分成单个输入。他会自动计算first,follow,预测分析表的构造，但并不输出。-importation has been eliminated and left recursive public from the left-LL (1) grammar, further importation of the corresponding expression, if the analysis is successful, the output of the recursive process output "belongs", if successful, there were errors and the corresponding location named. Attention, we should end with a non-escalation of production into a single input. He will be automatically calculated first, follow, and predicting and analyzing the table structure, but does not export.

这是我课程设计的时候编的一个simple 语言的词法分析器,可以运行,希望大家支持-This is my time courses designed a series of simple language the lexical analyzer, can run, we hope that the support

算符优先实验,可以输入文法，生成算符优先表，输入句子，生成移近-规约过程。并且还有实验报告。-operator priority experiments can be imported grammar, production operator priority list, input sentence, approached generation-the Statute of the process. And there are experimental report.
