yaml-config-loader

Takes care of loading configuration from yaml file and validating it using schema.

Example

config.yml:

required_string: abc
section:
  subsection:
    required_int: 123

Custom loader class with defined schema:

import ycl

class MyConfig(ycl.Config):

    schema = {
        "required_string": ycl.StringEntry(required=True),
        "section": {
            "subsection": {
                "required_int": ycl.IntegerEntry(required=True)
            },
            "optional_int": ycl.IntegerEntry(),
        }
    }

Load configuration using our class:

cfg = MyConfig.from_file('config.yml')

cfg.required_string
>>> u'abc'

cfg.section.subsection.required_int
>>> 123

cfg.dump()
>>> {'required_string': u'abc', 'section': {'subsection': {'required_int': 123}}}

If any required option is missing from configuration file or if it's invalid ConfigurationError will be raised.
