A tiny subset of YAML for JavaScript

yeahml

A JavaScript parser for a tiny subset of YAML — a minimal amount necessary to be useful for static site generators and simple configuration, while being small, strict and unambiguous. Inspired by StrictYAML. Experimental and a work in progress.

Key elements

• Key-value pairs (maps)
• Lists (sequences)
• Plain string values
• Single-quoted string values
• Double-quoted string values
• Multi-line string literals
• Comments

No intention to support

• Flow styles ({foo: bar, ...})
• Anchors and aliases (&ref)
• Explicit tags (!!int)
• Implicit typing (e.g. yes to true, timestamps)
• Complex keys (? foo : bar)
• Block headers (|+)
• Folded scalars (>)
• Directives (%YAML 1.2)
• Non-UTF-8 encodings
