View Source Spark.Dsl behaviour (spark v1.1.20)
The primary entry point for adding a DSL to a module.
To add a DSL to a module, add use Spark.Dsl, ...options. The options supported with use Spark.Dsl are:
:single_extension_kinds(list ofatom/0) - The extension kinds that are allowed to have a single value. For example:[:data_layer]The default value is[].:many_extension_kinds(list ofatom/0) - The extension kinds that can have multiple values. e.g[notifiers: [Notifier1, Notifier2]]The default value is[].:untyped_extensions?(boolean/0) - Whether or not to support anextensionskey which contains untyped extensions The default value istrue.:default_extensions(keyword/0) - The extensions that are included by default. e.g[data_layer: Default, notifiers: [Notifier1]]Default values for single extension kinds are overwritten if specified by the implementor, while many extension kinds are appended to if specified by the implementor. The default value is[].:opt_schema(keyword/0) - A schema for additional options to accept when callinguse YourSparkThe default value is[].
See the callbacks defined in this module to augment the behavior/compilation of the module getting a Dsl.

Schemas/Data Types
Spark DSLs use a superset of NimbleOptions for the schema that makes up sections/entities of the DSL.
