A from-scratch YAML parser and serializer library for Go, developed as a replacement for go-yaml/yaml. It offers higher YAML test suite coverage, intuitive validation errors, and AST-based reversible transformations including comments and anchors/aliases.

Use cases

• parse yaml configuration files in go
• marshal go structs to yaml
• unmarshal yaml into go structs
• preserve comments when transforming yaml
• get meaningful validation errors from yaml configs
• replace go-yaml/yaml in an existing project

When to choose

• you need better YAML spec coverage than go-yaml/yaml
• you need reversible YAML transformations with comments or anchors/aliases via AST
• you want intuitive, source-aware error messages for config validation
• you want a dependency-free, actively maintained YAML library

When to avoid

• you need drop-in compatibility with gopkg.in/yaml.v3 APIs
• your project already depends on sigs.k8s.io/yaml or ghodss/yaml and you don't want to migrate
• you only need trivial YAML handling and the de facto standard suffices
