YAML: The Norway Problem (2022)

a year ago

YAML's boolean parsing can incorrectly interpret certain values like 'NO' as 'False' due to its regex pattern.
This issue, known as 'The Norway Problem', occurs because 'NO' is parsed as a boolean false in YAML.
To avoid this, values can be escaped in double quotes or libraries like StrictYAML can be used to prevent unwanted conversions.
Other problematic YAML conversions include version numbers ending in '.0' being treated as numbers and last names like 'Null' being converted to NULL.
