YAMLStar

A YAML 1.2 reference framework for all programming languages.

Overview

YAMLStar is a YAML 1.2 reference framework providing 100% specification-compliant parsing with cross-language consistency. YAMLStar delivers the same behavior across 10 programming languages.

What is YAMLStar?

YAML 1.2 Reference Framework

YAMLStar is:

  • 100% YAML 1.2 compliant - Full specification implementation
  • Zero dependencies - No external libraries required
  • Cross-language - Available in 10 languages with identical behavior
  • Extensible - Plugin system for custom functionality (planned)

The Problem YAMLStar Solves

Most YAML libraries implement different subsets of the specification, leading to inconsistent behavior across languages. YAMLStar provides:

  • Consistent parsing - Same behavior in every language
  • Full compliance - Complete YAML 1.2 specification support
  • Pure implementation - No native code dependencies
  • Predictable behavior - Well-tested against specification edge cases

Available Languages

YAMLStar is currently available in:

  • Clojure - Original implementation
  • C# - .NET support
  • Delphi - Pascal support
  • Fortran - Scientific computing
  • Go - Modern systems programming
  • Java - JVM support
  • Node.js - JavaScript runtime
  • Perl - Systems scripting
  • Python - Data science and automation
  • Rust - Safe systems programming

All implementations share the same core logic and test suite, ensuring identical behavior.
