The JET Code Generator connects to any JDBC-based database and exports the schema as an XML-formatted file, and then generates code based on XSL Transformations. The user is free to write/modify XSLTs to generate virtually any type of source code from the XML representing your database schema. A complete example is included with a database, support classes, XSL Transformations, and build scripts (ANT and batch).
gtklean is a C header file generated directly from the GTK+ headers to provide a visually cleaner and less error prone C API for GTK+. It eliminates gtk_ prefixes in front of every GTK+ function. It automatically inserts calls to the type checking and casting macros for arguments that require them (e.g. GTK_WIDGET() and GTK_SIGNAL_FUNC()) so you can't forget them and never need to see them. It also replaces the string literals used for signal names with C identifiers to replace run time errors with compile time errors.
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.
Talend Open Studio for Data Integration is an ETL (Extract, Transform, and Load) tool. Talend Open Studio for Data Integration can perform jobs that range from datawarehouse feeding to database synchronization, as well as file format transformations. Its graphical interface is made with Eclipse RCP, and data related scripts are generated in Perl or Java. The application was designed to be extended with components written by users.
The Quick C-- compiler is an experimental implementation of the C-- language. C-- is intended to be a "portable assembly language" that can be used as a target language by compiler writers. C-- features a simple C-like core and support for garbage collection and exception handling.
Python to C Module Generator was designed to aid in the conversion of Python modules to C extension modules while keeping the same interface into the module. This makes it easier to convert existing Python code into C code, giving it a speed boost without changing to existing code.
