Expressive statecharts and FSMs for modern Python.

A python framework base on David Harel's statecharts (SCXML).

[Tool][Functional] Generate state machine in C++ from PlantUML statecharts

A small, blazing fast, functional zero-dependency and immutable Finite State Machine (StateCharts) library implemented in Python. Using state machines for your components brings the declarative programming approach to application state.

Generate Harel-style statecharts from plain-English requirements — SVG, Mermaid, and an editable JSON model, with semantic and layout validation. Zero dependencies.
