朋友给的一个产品的demo程序，说是对学单片机的朋友极其有用...

编译的作业，对词法的分析分类以及发现错误，希望与大家交流，谢谢指教-Task of Compiler Implementation,To analyse and find error of Lexical,wish to communication with you,thanks.

一个简单的编译器，可以实现简单的画图语句的解析，最终画出简单的图形。涉及程序编译器的实现几个步骤，词法分析，语法分析，语义分析，等等。-a simple compiler can achieve a simple drawing of analytic statement, the final draw simple graphics. The procedures compiler in several steps, lexical analysis, grammar analysis, semantic analysis, and so on.

本程序包括详细的词法分析，语法分析，语义分析和中间代码生成，写得很不错，可读性很强。是关于循环语句的翻译-this procedure include a detailed analysis of the morphology, syntax, semantic analysis and intermediate code generation, very good, very readable. On the loop is the translation

一个多线程，多流程的脚本编译解释平台，能够同时运行多份脚本代码，流程可以直接加载任意接口的动态库，执行数据库库访问，存储过程和sql语句，加载支持双接口的com，支持多机通讯，曾用于cti开发，-A multi-threaded, multi-process platform to explain the script compiler that can run multiple copies of the script code, the process can directly interface to load arbitrary dynamic library, the implementation of the database library access, stored procedures and sql statements, support for dual-interface load com in support of multi-machine communications, CTI has been used for development,

使用Java语言实现Small Basic语言解释器。包括两个主要的子系统：一个是表达式解释器，负责处理数字表达式；另一个是解释器，负责程序的实际执行。-use Java language Small Basic language interpreter. Including the two major subsystems : an expression interpreter is responsible for handling digital expression; Another interpreter, responsible for the actual implementation process.

一个简单的词法分析器，可以识别C++中的关键字、标识符、数值、各种合法字符等，能对一段正确或含有错误的C++程序进行词法分析，并对错误进行精确的提示。-A simple lexical analyzer to identify C++ Of keywords, identifiers, values, a variety of legal characters, etc., can contain a section of right or wrong C++ Procedures lexical analysis, and errors accurate advice.

词法分析程序设计 1、给出各单词符号的类别编码。 2、词法分析程序应能发现输入串中的错误。 3、词法分析作为单独一遍编写，词法分析结果为二元式序列组成的-Lexical analysis program design one, given the various types of code word symbols. 2, lexical analysis procedure should be able to detect errors in the input strings. 3, again as a separate lexical analysis prepared for morphological analysis of binary sequence composed of

一个flex和bison用法入门的很好的例子。　按照词法分析,语法分析,语义分析的顺序来熟悉flex和bison这两个有力的工具。最后给出了一个用flex做词法分析用bison做语法分析设计的科学计算器（不同于一般程序设计中的入门级计算器），是学习编译原理的很好的例子。-a flex and bison portal usage of a very good example. According lexical analysis, parsing, Semantic analysis of the sequence to flex and bison familiar with these two powerful tool. Finally, a use flex do lexical analysis bison do syntax analysis and design of scientific calculators (unlike General Program Design"s entry-level calculators), compiler theory is the study of good examples.
