Shannon is a general purpose stream-oriented programming language; it is concise and yet feature rich. Streams, FIFOs, and Unix shell-style pipes are first-class concepts in the language. You can connect functions and FIFOs within your program similar to the way you connect processes with pipes in the Unix shell. These constructs in Shannon, however, are highly efficient as no true multitasking is involved, and at the same time they allow you to write more concise and readable code for chained data processing. State is a special type of function that returns a reference to its own local data and any nested functions it may have. In effect, states implement classes in terms of OOP, and yet classes per se aren't part of the language. A special type of modules marked as "persistent" is an effective replacement for databases and SQL. This allows you to access persistent shared data using native Shannon constructs, eliminating the need for an extra query language. Intuitive and minimalist syntax and semantics are used. Particularly, "minimalist semantics" means less things to remember and more possibilities. Shannon is statically-typed, although it provides dynamic typing facilities as well.
The Voodoo compiler is an implementation of the Voodoo programming language. The Voodoo programming language is a low-level programming language, abstracting over the platform's instruction set and calling conventions, but otherwise leaving the programmer free to do anything at all. The Voodoo compiler supports multiple target platforms and provides a stand-alone compiler, as well as a Ruby module for programmatic code generation.
The GNU Modula-2 compiler is one of a number of front end languages to GCC (the GNU Compiler Collection). As such, it has been designed to coexist with other GCC languages. For example, it can be used in mixed language projects and it can catch C++ exceptions and throw exceptions which can be caught by C++. Users can also exploit conditional compilation and full gcc backend optimization and architecture coverage. GNU Modula-2 can produce position independent code and can easily produce shared libraries from modules. The compiler provides a swig interface file generator option, which allows scripting languages such as Python to import modules written in Modula-2 and also catch exceptions thrown by Modula-2. The compiler translates PIM2, PIM3, PIM4, and ISO dialects of Modula-2.
