SMAL (State Machine Abstraction Language) is a compact, human‑readable YAML DSL for defining fully functional state machines that are:
- Simple — easy to write, easy to read
- Robust — validated, structured, and type‑safe
- Debuggable — designed for real firmware workflows
A .smal file describes your entire state machine — states, events, transitions, commands, messages, and error handling — in a clean, declarative format. From that single source of truth, SMAL can generate:
- C, C++, and Rust firmware code
- A complete SVG state machine diagram
- Debug structures for introspection and tooling
- Human-readable reports for developers and QA
SMAL is built for embedded systems, audio devices, wearables, robotics, and any environment where clarity, determinism, and debuggability matter.
✨ Features
🧩 YAML-based DSL
Define states, events, transitions, actions, etc. in a clean, expressive format.
🔧 Multi-language code generation
Generate firmware-ready code in C. C++ and Rust planned for future release.
🖼️ SVG diagram generation
Produce a polished, auto‑layout state machine diagram directly from your .smal file.
🐞 Debug-friendly
SMAL includes a structured debug layout that maps cleanly to firmware and tooling.
🛠️ Extensible
Add custom generators, validators, or analysis tools.
📦 Installation
