Python语言编译器 -Python compiler

动态哈夫曼编码-Dynamic Huffman coding

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.

Grammatica is a C# and Java parser generator (compiler compiler). It improves upon simlar tools (like yacc and ANTLR) by creating well-commented and readable source code, by having automatic error recovery and detailed error messages, and by support for testing and debugging grammars without generating source code. It supports LL(k) grammars with an unlimited number of look-ahead tokens.

C语言来构造编译器的,十分详细的源代码，还有注释-on the use of C language compiler construction, the site has its source code matching.

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.
