yamleam/scalar

Plain scalar resolution.

Converts the verbatim text of a plain (unquoted) scalar into a typed YamlNode according to YAML 1.2 resolution rules. Quoted scalars are always strings and bypass this layer entirely.

Resolution priority (first match wins):

1. Empty / “null” / “Null” / “NULL” / “~” → YamlNull
2. “true” / “True” / “TRUE” → YamlBool(True)
3. “false” / “False” / “FALSE” → YamlBool(False)
4. Decimal integer (optional sign) → YamlInt
5. Decimal float (optional sign, exponent) → YamlFloat
6. Otherwise → YamlString

Following YAML 1.2, the YAML 1.1 boolean variants (“yes”, “no”, “on”, “off”) and leading-zero octals (“0777”) resolve as strings. Hex and octal integers (“0x1F”, “0o17”) and the special floats (“.inf”, “.nan”) currently resolve as strings too.
