What is Anchors?

A teaching and conversion tool for YAML anchors (&name) and aliases (*name): it shows what each anchor expands to and emits the fully resolved document.

How it works

js-yaml resolves aliases natively during parsing; the tool also scans the source for anchor definitions and alias references and lists them with line numbers.
