smal-lang 0.4.1

State Machine Abstraction Language (SMAL) is a YAML-based description language for simple, robust and debuggable state machines.

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
