#205 Detect duplicate keys as an error #206

Closed fktn-k closed 11 months ago

fktn-k commented 11 months ago

The YAML specification says mapping keys must be unique, but fkYAML doesn't check duplication of keys while parsing the input stream.
To follow the specification, this PR has fixed the bug.

Furthermore, to check that the fix works as expected, a new test case has also been added.
