Environment Variables
=====================

The Library and CLI uses a few environment variables to simplify some access.

  :header-rows: 1

  * - Environment Variable
    - Default Value
    - Description
  * - ``SKA_SCHEMAS_CACHE``
    - ``None``
    - Specify the location of the cache directory. By default this uses your user's cache directory
  * - ``SKA_SCHEMAS_ALLOW_STRICT_VALIDATION``
    - ``None``
    - Specifies whether strict validation is allowed to raise errors
      about superflous fields. This is typically only a good idea in
      unit and integration tests.
  * - ``SKA_SCHEMAS_ALLOW_DEV_VERSION``
    - ``False``
    - If set to True, development versions of schemas are also allowed to be loaded.
