SCION provides a system for developing with SCXML/Statecharts in JavaScript
This module adds support for generating source maps to the SCION compiler. This enables a visual JavaScript debugger, like Chrome DevTools or VSCode, to read the sourcemap, set breakpoints in the SCXML source file, and inspect the SCXML datamodel. This wo

statecharts: hierarchical, reactive state machines
Fast, lightweight access to simple xml data.
This gem implements all core constucts of the state chart XML (SCXML) specification of the W3C. (http://www.w3.org/TR/scxml/) Instead of implementing an interpreter, this gem implements a parser that create a ruby statemachine instance based on the MINT-statemachine gem (https://github.com/sfeu/statemachine).
scjson: SCXML ↔ JSON converter, validator, and execution trace interface. Provides CLI tools for conversion, validation, and emitting deterministic traces compatible with SCION semantics.
