YAML Implementations¶

Core YAML Libraries and Tools¶

YAML has been implemented in many programming languages, providing developers with native access to YAML functionality across different platforms and ecosystems.

Official Implementations¶

libyaml¶

Language: C
Repository: yaml/libyaml
Status: Production Ready

The reference C implementation of YAML, providing fast and efficient parsing and emission capabilities.

Features: - Full YAML 1.2 compliance - High-performance parsing - Memory-efficient processing - Cross-platform compatibility - Extensive testing suite

Use Cases: - High-performance applications - System-level tools and utilities - Language bindings and wrappers - Embedded systems

PyYAML¶

Language: Python
Repository: yaml/pyyaml
Status: Production Ready

The most popular Python YAML implementation, widely used in Python ecosystems.

Features: - YAML 1.2 specification support - Safe and unsafe loading modes - Custom tag support - Comprehensive error handling - Active maintenance

Use Cases: - Python applications and scripts - Configuration management - Data processing pipelines - Web applications

go-yaml¶

Language: Go
Repository: go-yaml/yaml
Status: Production Ready

Native Go implementation providing idiomatic YAML support for Go applications.

Features: - YAML 1.2 compliance - Go-native data structures - High performance - Comprehensive testing - Active development

Use Cases: - Go applications and services - Cloud-native applications - Microservices - CLI tools

Choosing an Implementation¶

Language Requirements¶

Native support - Use implementations in your primary language
Performance needs - Consider C implementations for high-performance apps
Platform constraints - Ensure compatibility with your deployment environment

Feature Requirements¶

YAML version - Ensure 1.2 compliance for modern applications
Custom tags - Check support for your specific YAML extensions
Error handling - Evaluate error reporting and recovery capabilities

Support and Maintenance¶

Official implementations - Professional support through YES program
Community implementations - Community-driven support
Update frequency - Regular security and feature updates

Future Development¶

YAML 2.0 Support¶

All official implementations will be updated to support YAML 2.0 when it's released.

Planned improvements: - Enhanced security features - Better performance characteristics - Improved error handling - Extended customization options

YES Program Influence¶
