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++.
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.
ClearParse is a flexible engine that can be used for any parsing task including interpreting or compiling programming languages, analyzing or converting data files, processing command line parameters and user input, implementing markup languages and scripts, natural language processing (NLP), and more.
Genscreen generates C or C++ code using ncurses library functions for building I/O screens. Screen layouts are designed using any text editor (vi, emacs, etc.), then the layout file is run through Genscreen and automatically converted to compilable C/C++ code. Once the basic screen code is generated it can be edited, have additional features added, or be merged with other code. Genscreen also includes automatic date field generation for both US and European date formats, and support for generating money fields.
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.
