sid

sid is a modern stack-based language: Forth-like in its low-level control and FFI friendliness, Joy-like in its functional composition via quotations/closures, with a simple flexible type system and built-in lightweigth data structures.

See docs/README.md for an introduction into the language and its syntax.

See SPECULATIONS.md for wilder ideas for where the language could develop.

Building

Without LLVM (interpreter only):

cargo build
cargo run --bin sid -- <source-file>

With LLVM backend (requires LLVM 18 — use nix develop):

nix develop -c cargo build --features llvm
nix develop -c cargo run --bin sid-llvm -- --emit-llvm

Testing

cargo test
