class Bunto::Configuration
Constants
- DEFAULTS
Default options. Overridden by values in _config.yml. Strings rather than symbols are used for compatibility with YAML.
Public Class Methods
Static: Produce a Configuration
ready for use in a Site
. It takes the input, fills in the defaults where values do not exist, and patches common issues including migrating options for backwards compatiblity. Except where a key or value is being fixed, the user configuration will override the defaults.
user_config - a Hash or Configuration
of overrides.
Returns a Configuration
filled with defaults and fixed for common problems and backwards-compatibility.

Public: Ensure the proper options are set in the configuration to allow for backwards-compatibility with Bunto
pre-1.0
Returns the backwards-compatible configuration
