Onyx is a powerful stack-based, multi-threaded, interpreted, general purpose programming language similar to PostScript. It can be embedded as an extension language similarly to ficl (Forth), guile (scheme), librep (lisp dialect), s-lang, Lua, and Tcl.
Onyx is perhaps the most advanced stack-based general purpose programming language in existence It has the following distinguishing features:
- Double-ended stacks are first class objects
- Perl-compatible regular expressions.
- Loadable module system.
- Object-oriented programming (OOP) support similar to that of Objective-C
