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.

New: Editor Manual

New: Workflow Guide

https://github.com/ha1tch/fsm-toolkit/blob/main/WORKFLOWS.md

Highlights

% Multi-document bundles with import and cross-machine navigation
% Class and property system with 7 typed fields
% Component drawer with drag-and-drop instantiation
% 74xx-series class libraries (49 components across 7 families)
% Machine manager with rename/delete and link propagation
% Settings screen with vocabulary customisation and library loading
% Improved TUI layout engine with cell-grid metrics
% CI/CD pipeline targeting 12 platforms (Linux, macOS, Windows, FreeBSD, OpenBSD, NetBSD)
% Separate CLI and editor manuals
% 261+ tests passing

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)

🙋 Do you use XState + React?

Make yourself known in the State of React 2023 survey! XState is under State Management 😊

@marcosh I'm watching your state machine talk @ https://www.youtube.com/watch?v=UBnHpnss8Fg

Really cool stuff :-) #statemachines #eventsourcing #fp

Really good video from @noboilerplate

I haven't seen many people talk about state machines outside the game dev world

Wow, this is the 20th anniversary edition of the book. 👴

It's great that he put it online where anyone can read it. TBH, I thought there would be a more visible effect of this work by now.

The fact that it hasn't is evidence of how compartmentalized & isolated the specialized fields of knowledge have become. Each prefers their own jargon & narrative, and is built on the shoulders of *their* giants, blurring the distinction between communities of religion & science. Newcomers are outsiders, and often ostracized from the in-group.

Random 3am thoughts while burping a baby…

With a finite state machine, you can persist the state or the transitions. In simple, non cyclical, unidirectional machines, sequence and not time based, storing state is fantastic - you can know all of the events that have happened previously.

But… how often are we that lucky?
