A composable pattern for pure state machines with effects

State machines are everywhere in interactive systems, but they're rarely defined clearly and explicitly. Given some big blob of code including implicit state machines, which transitions are possible and under what conditions? What effects take place on what transitions?

There are existing design patterns for state machines, but all the patterns I've seen complect side effects with the structure of the state machine itself. Instances of these patterns are difficult to test without mocking, and they end up with more dependencies. Worse, the classic patterns compose poorly: hierarchical state machines are typically not straightforward extensions. The functional programming world has solutions, but they don't transpose neatly enough to be broadly usable in mainstream languages.

Here I present a composable pattern for pure state machiness with effects,

How to automate the build of bottles on your Homebrew tap

Note on Oct 4, 2018: due to a change in Homebrew's brew test-bot behaviour, the user must set HOMEBREW_TRAVIS_CI and HOMEBREW_TRAVIS_SUDO appropriately (it was previously using Travis-CI-provided TRAVIS and TRAVIS_SUDO).

This tutorial is a follow-up to the discussion we had on davidchall/homebrew-hep#114. It relies on a fork of the test-bot provided by davidchall; you can get it with brew tap maelvalais/test-bot. First:

1. the Github project must be of the form https://github.com//homebrew- with the following tree
