r"""YAML backend:
|
|
|
|
- Format to support: YAML, http://yaml.org
|
|
- Requirements:
|
|
|
|
- ruamel.yaml, https://bitbucket.org/ruamel/yaml
|
|
- or PyYAML (yaml), http://pyyaml.org
|
|
|
|
- Development Status :: 5 - Production/Stable
|
|
- Limitations:
|
|
|
|
- Resuls is not ordered even if 'ac_ordered' or 'ac_dict' was given if PyYAML
|
|
is used as the YAML backend.
|
|
|
|
- Special options:
|
|
|
|
- All keyword options of yaml.safe_load, yaml.load, yaml.safe_dump and
|
|
yaml.dump should work. Also, some keyword options specific for ruamel.yaml
|
|
are supported to enable some its own features PyYAML does not have.
|
|
|
|
- Use 'ac_safe' boolean keyword option if you prefer to call yaml.safe_load
|
|
and yaml.safe_dump instead of yaml.load and yaml.dump. Please note that
|
|
this option conflicts with 'ac_dict' option and these options cannot be
|
|
used at the same time.
|
|
|
|
- See also: http://pyyaml.org/wiki/PyYAMLDocumentation and
|
|
https://yaml.readthedocs.io/en/latest/
|
|
|
|
Changelog:
|
|
|
|
.. versionchanged:: 0.9.8
|
|
|
|
- Split PyYaml-based and ruamel.yaml based backend modules
|
|
- Add support of some of ruamel.yaml specific features.
|
|
|
|
.. versionchanged:: 0.9.3
|
|
|
|
- Try ruamel.yaml instead of yaml (PyYAML) if it's available.
|
|
|
|
.. versionchanged:: 0.3
|
|
|
|
- Changed special keyword option 'ac_safe' from 'safe' to avoid
|
|
possibility of option conflicts in the future.
