Generate Elm code from a supplied JSON sample string using the supplied options.

The output consists of:

• a set of imports
• a set of type and type alias definitions
• a set of decoder defintions
• a set of encoder definitions.

    ElmCodeGenerator.fromJsonSample
        { rootTypeName = topLevelTypeName
        , decodeImport = { importAlias = "Json.Decode", exposingSpec = ElmCodeGenerator.ExposingNone }
        , encodeImport = { importAlias = "Json.Encode", exposingSpec = ElmCodeGenerator.ExposingNone }
        , decoderStyle = ElmCodeGenerator.PlainDecoders
        , namingStyle = ElmCodeGenerator.NounNaming
        }
        """{"a": 1, "b": "str"}"""

Defines the style of decoders to generate:

• Applicative decoders use andMap from elm-community/json-extra
• Pipeline decoders use functions from NoRedInk/elm-json-decode-pipeline
• Plain decoders only use elm/json functions

Defines what's exposed for an import

Options for code generation given to fromJsonSample

Details of an import

Defines function naming style:

• Verb naming will produce names like decodeThing
• Noun naming will produce names like thingDecoder

Output Elm strings produced by fromJsonSample
