Red: A Powerful, Self-Hosted, Cross-Platform Systems Programming Language

Red is a programming language strongly inspired by Rebol, but with a broader field of usage thanks to its native-code compiler, from system programming to high-level scripting, while providing modern support for concurrency and multi-core CPUs. Red tackles software building complexity using a DSL-oriented approach (dialects). Built-in dialects include Red/System (a C-level system programming language), Parse (a powerful PEG parser), VID (a simple GUI layout creation dialect), Draw (a vector 2D drawing dialect), and Rich-text (a rich-text description dialect). Red has its own complete cross-platform toolchain, featuring an encapper, a native compiler, an interpreter, and a linker, not depending on any third-party library (except during the alpha stage). Key features include human-friendly syntax, homoiconicity, multi-typing, a powerful pattern-matching macro system, a rich set of built-in datatypes, both static and JIT compilation, cross-compilation, small executables (<1MB), strong concurrency and parallelism support, low-level system programming abilities, a powerful PEG parser DSL, a fast and compacting garbage collector, built-in instrumentation, a cross-platform native GUI system, JVM bridging, high-level scripting, and REPL GUI and CLI consoles. Currently in alpha and 32-bit only.
