The Free Pascal Compiler is a Turbo Pascal 7.0 and Delphi-compatible 32/64 bit Pascal Compiler. It comes with a fully TP 7.0-compatible run-time library. Some extensions have been added to the language, like function overloading. Shared libraries can be linked. Basic Delphi support is implemented with classes, exceptions, RTTI, and ansistrings. A Free Component Library (FCL) is available with the base classes. Bindings for X11, ncurses, GTK, OpenGL, zlib, mysql, interbase and postgres are available.
FreeFrameWork adds robustness features and development environment enhancements to the WebSpeed web application server product from Progress Software. Among its features are proactive database connection checking and reconnection, enhanced logging and security, and compile-on-the-fly HTML. Also included are enhancements to the workshop, with better filetools and a database schema viewer.
gbeta is an advanced OO language which supports virtual attributes, general block structure, and dynamic inheritance in context of strict, static typing. It is a generalization of the language BETA. This package includes an implementation of the language which performs static analysis, generates byte code, and runs the given program. It is integrated with GNU Emacs and programs can be single stepped, declarations can be looked up by double-clicking etc. in this environment.
The GNU Compiler Collection contains frontends for C, C++, Objective-C, Fortran, Java, and Ada as well as libraries for these languages. It is a full-featured ANSI C compiler with support for K&R C as well. GCC provides many levels of source code error checking traditionally provided by other tools (such as lint), produces debugging information, and can perform many different optimizations to the resulting object code.
The ANTLR ANSI C and GCC source to source translation framework includes an ANSI-C parser which builds trees, a GCC parser which builds trees, a GCC tree parser (for you to subclass to do transformations), and a GCC tree emitter. The GCC parser is only for GCC's extensions to C, not C++. It is based on GCC 2.95.2.
Gforth is a fast and portable implementation of the ANS Forth language. It works nicely with the Emacs editor, offers some nice features such as input completion and history and a powerful locals facility, and it even has (the beginnings of) a manual. Gforth employs traditional implementation techniques: its inner innerpreter is indirect or direct threaded. Gforth runs under Unix, Win95, OS/2, and DOS and should not be hard to port to other systems supported by GCC.
