lisp

A performance oriented lisp language intepreter using a register-based bytecode VM written in ASM.

The goal is to achieve performance within the same order of magnitude compared to C code compiled without optimizations (realistically maybe 2x-3x slower in general).

Building and running

Building requires NASM assembler, make and a C compiler.

make

To run the REPL:

./rex

To run code in a file:

./rex [filename]

Running an example

Run an example (requires OpenGL and SDL3):

./rex example/opengl_triangle.lisp

An example benchmark program (sum of numbers up to 1e8):

(let (a 0) (for (i 100000000) (++ a i)) a)
