Constructor Details

#initialize(source_path: nil, skill_path: nil, base_path: nil) ⇒ void

Parameters:

  • source_path (String) (defaults to: nil) —

    The path to the source directory containing readable files.

  • skill_path (String) (defaults to: nil) —

    Deprecated alias for source_path.

  • base_path (Pathname, String) (defaults to: nil) —

    The base path to resolve the source directory against.

Raises:

  • (TypeError) —

    when the provided source or base path cannot be converted into a pathname.

Class Method Details

.call(params) ⇒ Hash

Loads and formats source context files.

Parameters:

  • params (Hash) —

    The configuration for context hydration.

Options Hash (params):

  • :source_path (String) —

  • :base_path (Pathname, String) — default: optional —

    The base path to resolve the source directory against.

Returns:

  • (Hash) —

    A result hash with :success, and :response containing the XML formatted context.

Raises:

  • (TypeError) —
