Callisto

Callisto is a reverse Polish notation programming language, inspired by YSL-C3 and Forth. It also includes a subset called CallistoScript, designed for compiling to scripting languages like Lua, while still maintaining a relatively low-level approach.

• x86_64 Linux, macOS: Fully supported
• ARM64 Linux, macOS: Fully supported
• Uxn: Fully supported
• Lua: Fully supported (subset: CallistoScript)

Build Instructions

To build the Callisto compiler, you will need a D compiler. Once installed, build the project using the following command:

dub build

Getting Started

Running Example Programs

Before running example programs, ensure that the std submodule is included in your repository. You can achieve this by cloning the repository recursively or running the following command:

git submodule update --init --remote --recursive

Example programs are located in the examples directory. To compile and run an example, use:

cac examples/<exampleName>.cal -i std -o out
./out
