Callisto

Callisto is a reverse polish notation programming language inspired by YSL-C3 and Forth

It also has a subset called CallistoScript made for scripting languages like Lua, and it's still sort of low level

Supported targets

• x86 real mode, MS-DOS (complete)
• x86_64 Linux, macOS (complete)
• ARM64 Linux (complete)
• Uxn (complete, implement broken, see #6)
• Lua (complete, subset CallistoScript)

Build

You need a D compiler to build the Callisto compiler

dub build

Try it

Note: to use the example programs, you will need the std submodule in this repository, which you can get by cloning recursively or doing git submodule update --init --remote --recursive

There are some example programs in the examples folder, which you can compile and run like this:

cac examples/exampleNameHere.cal -i std -o out
./out
