TOON format (v0)

• Objects: { key = value, other = value }
• Arrays: [ value, value ]
• Strings: double or single quoted with backslash escapes
• Numbers: JSON-style numbers
• Booleans: true / false
• Null: null
• Keys: bare identifiers ([A-Za-z_][A-Za-z0-9_-]*) or quoted strings
• Whitespace is ignored
• Trailing commas are allowed in arrays/objects

This format is intentionally small and deterministic to keep parsing and stringifying dependency-free.

API

• toToon(value, options?)
  • options.indent (default 2, set to 0 for minified)
  • options.quoteKeys (default false, force quoted keys)
• fromToon(text)
