About

Callisto is a compiled, low-level, concatenative language inspired by Forth.

Currently, the compiler supports compiling for these targets:

• x86_64 - Linux and macOS
• x86 real mode - MS-DOS and bare metal
• ARM64 - Linux and macOS
• Lua, subset CallistoScript
• Uxn

Callisto also has a subset called CallistoScript, which is compiled to scripting languages but remains somewhat low-level. Right now, CallistoScript only supports compiling to Lua. Learn more

Examples

Hello World

include "cores/select.cal"
include "std/io.cal"

"Hello, world!\n" printstr
