This micro library is a PyYaml wrapper with sane behaviour to read and write readable YAML safely, typically when used with configuration files.

With saneyaml you can dump readable and clean YAML and load safely any YAML preserving ordering and avoiding surprises of type conversions by loading everything except booleans as strings.

Optionally you can check for duplicated map keys when loading YAML.

Works with Python 3. Requires PyYAML 5.x or higher.
