Welcome to the world of Statecharts

The world of statecharts describes what statecharts are, their benefits and drawbacks, how they differ from state machines, and practical examples on how to use them.

Release: fsm-toolkit v0.9.5

fsm-toolkit is a Go toolkit for designing and analysing finite state machines. It provides a CLI tool (fsm) and a full TUI editor (fsmedit) supporting DFA, NFA, Mealy, and Moore machines — with multi-machine bundles, cross-machine linking, and a component system backed by reusable class libraries.

Repo:

https://github.com/ha1tch/fsm-toolkit#readme

This is the biggest release since the project's inception bringing a component-oriented workflow to FSM design. You can now drag 74xx-series digital logic parts from a library drawer, assign typed properties to states, link machines into bundles, and manage it all from the TUI. Builds and releases for 12 platforms are now fully automated.

NES Games & State Machines
A couple of years ago gamedev channel NesHacker did a video on how everything in your typical NES game is really a pile of state machines, concurrent ones, nested ones, bunches and bunches of them. If you have any interest in NES coding at all, it's worth a look. (8½ minutes)
