Beige is a WIP Operating system, designed to run Lisp programs in userspace, with a C kernel to manage low level details and interpret Lisp code.
The Lisp dialect that Beige implements is a single namespace (Lisp-1) scheme-like Lisp. All Lisp related code is inside the lisp directory. The parser and interpreter are still rather crude, but functional. The parser is a recursive descent parser, written in C. Contrary to McCarthy 1960, the Environment, or lexical scope, is implemented as a C struct rather than an associative list.
A few types exist to help interoperation between high level Lisp and machine code.
| u8 | u16 | u32 | Num | Sym | Fun |
| 8bit unsigned | 16bit unsigned | 32bit unsigned | Numeric type | Symbol | Function |
