linux shell 得词法分析器，用于shell的命令解释。

编译器 带报告-compiler with the report SUMMARY

前些天写了个小语言的词法分析程序，因为前些天在VC知识库看到一个pascal词法分析的程序，觉得写得挺复杂的。其实词法分析程序的原理都是一样的，所以我想只要搞明白了简单的词法分析程序，再写复杂的就不难了，无非是多加几个关键字，多写几个条件判断语句而已。词法分析是编译程序的基础，也是最简单的。好，现在让我们看程序吧。 先让我们看看这个小语言的文法吧-few days ago wrote a small language lexical analysis procedures, because the other day in the knowledge base to see a VC pascal lexical analysis procedures, find that quite complex. In fact, lexical analysis procedure is the same principle, I think if you understood a simple lexical analysis procedure to write complex it is not difficult, is nothing but add a few keywords and writing several conditions judgment statement it. Lexical analysis is the basis of compilers, as well as the most simple. Well, now let us look at the procedures it. Let us look at this small language grammar it

符合编译原理的词法分析器- Conforms to the translation principle morphology analyzer

通过设计编制调试一个具体的词法分析程序，加深对词法分析原理的理解。并掌握在对程序设计语言源程序进行扫描过程中将其分解为各类单词的词法分析方法。-Debugging through the design of the preparation of a specific lexical analysis process, deepen their understanding of the principles lexical analysis. And mastery of programming language source code to scan the process of its decomposition for different types of word lexical analysis.

一般的FOrtran程序编译器只能检查一般的错误，而这个软件可以起到一般编译器不能起到的错误检查、程序优化作用。-Ftnchek (short for Fortran checker) is designed to detect certain errors in a Fortran program that a compiler usually does not. Ftnchek is not primarily intended to detect syntax errors. Its purpose is to assist the user in finding semantic errors. Semantic errors are legal in the Fortran language but are wasteful or may cause incorrect operation. For example, variables which are never used may indicate some omission in the program uninitialized variables contain garbage which may cause incorrect results to be calculated and variables which are not declared may not have the intended type. Ftnchek is written in C. To build ftnchek, you must have a C compiler for the machine on which you wish to build it. The URL for ftnchek s home page is http://www.dsm.fordham.edu/~ftnchek. Source code, binary executables for some platforms, and other information are available there.

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

一个简单实用的自己编写计算器，非常非常非常好用。-Calculator

一款拥有一定历史的C语言编译器，最初为MOTOROLA 68000 开发，后来为其他一些通用处理器实现了后端，支持C99中的大部分新特性。-has some history of C language compiler, originally developed for Motorola 68000, Later, some of the other processor to achieve a common back-end, the C99 support most of the new properties.
