The cutils collection is composed of: cdecl and cundecl (decode and encode C type declarations), cobfusc (make a C source file unreadable but compilable), chilight (highlight C source files), cunloop (unloop C loops), yyextract (extract grammar rules from yacc grammar), and yyref (generate a cross-reference for yacc input).
Cheetah is a Python-powered template engine and code generator. It can be used as a standalone utility or it can be combined with other tools. Web developers are its principle user group, but it has many potential uses and is also being used to generate C++ game code, Java, SQL, form emails, and even Python code.
EFEU is suitable for handling data cubes, which are especially useful for building data warehouses. It consists of a building system including mkmf (a xmkmf like Makefile generator), esh (a powerful C/C++ interpreter), efeudoc (a document generator with different output formats (LaTeX, HTML, roff, etc.)). EFEU has a huge set of C library core features, including robust memory allocation tools, functions to concatenate and copy strings with memory allocation, buffers for dynamically-growing strings and fields, data structures with reference counters and garbage collection, and file tools that allow you to specify pipes wherever a filename is expected and support automatic implementation of (de)compression filters (gzip) depending on filename extensions. It also includes a high-level interface to files, strings, and anything else you can read from or write to.
Spirit is an object-oriented, recursive descent parser generator framework implemented using template meta-programming techniques. Expression templates allow Spirit to approximate the syntax of Extended Backus Normal Form (EBNF) completely in C++. The Spirit framework enables a target grammar to be written exclusively in C++. EBNF grammar specifications can mix freely with other C++ code and, thanks to the generative power of C++ templates, are immediately executable.
GNU Cim is a compiler for the programming language Simula (except unspecified parameters to formal or virtual procedures). It offers a class concept, separate compilation with full type checking, interface to external C routines, an application package for process simulation and a coroutine concept. Its portability is based on the C programming language. The compiler and the run-time system is written in C, and the compiler produces C code, that is passed to a C compiler for further processing towards machine code.
OpenC++ is a source code translation tool for C++. Programmers can easily implement various kinds of translation so that they can define new syntax, new annotation, and new object behavior. OpenC++ is useful if they need to, for example, develop extensions to C++, add domain-, application-, or class-specific compiler optimizations, or build their own version of (runtime) MOP for C++.
OpenJava allows programmers to customize the language to implement new language mechanism through MOP. OpenJava helps people who want to develop better Java libraries. It also helps people who are developing their own extended Java languages. OpenJava can also be regarded as a toolkit for constructing a Java preprocessor.
Javassist (Java programming assistant) is a load-time reflective system for Java. It is a class library for editing bytecodes in Java; it enables Java programs to define a new class at runtime and to modify a class file when the JVM loads it. Unlike other similar systems, Javassist provides source-level abstraction; programmers can use Javassist without detailed knowledge of the Java bytecode. This ease of use is a unique feature of Javassit against other tools.
PHP Generator of Object SQL Database generates objects from the description of table in an SQL database. Each object map is a table in the SQL database, and has methods to insert, modify, and delete an entry in the database. But they also have methods to show forms, and to get data after an HTTPD post, or a get. They have iterator methods, and call your function for each entry of your request. Some templates help you to write HTML forms. This can help when you change databases, as the API is the same all the time, and you don't have to patch the PHP objects, but just regenerate them.
phpHtmlLib is an application development framework for developing OOP style Web applications in PHP. The application framework supports an MVC style architecture and Ajaxable and Cacheable interfaces for developing rich client Web applications. It comtains a set of PHP classes and library functions to help facilitate building, debugging, and rendering of XML, HTML, XHTML, WAP/WML Documents, and SVG (Scalable Vector Graphics) images as well as complex HTML widgets.
