Module: Scarpe::CatsCradle

Defined in:
lib/scarpe/cats_cradle.rb

Overview

"Cat's Cradle" is a children's game where they interlace string between their fingers to make beautiful complicated shapes. The interlacing of fibers made it a good name for a prototype.

An attempt at an experimental Fiber-based control-flow system to deal with Shoes, Display and JS all at the same time.

In general, we'll use Fiber.transfer to bounce control back and forth between the evented implementations (e.g. waiting for redraw) that need to return control to Webview, and the procedural test flows that look far better if we don't do that explicitly.

Ruby Fiber basic docs: https://ruby-doc.org/core-3.0.0/Fiber.html

This module is mixed into an object to coordinate fibers app-wide.
