### Hocon Configuration Format

The Hocon Configuration Format extends the Vert.x Configuration Retriever and provides the support for the HOCON(https://github.com/typesafehub/config/blob/master/HOCON.md) format.

It supports includes, json, properties, macros…​

#### Using the Hocon Configuration Format

To use the Hocon Configuration Format, add the following dependency to the dependencies section of your build descriptor:

- Maven (in your `pom.xml`):

    <dependency>
      <groupId>io.vertx</groupId>
      <artifactId>vertx-config-hocon</artifactId>
      <version>3.5.0</version>
    </dependency>
    <dependency>
      <groupId>io.vertx</groupId>
      <artifactId>vertx-config</artifactId>
      <version>3.5.0</version>
    </dependency>

- Gradle (in your `build.gradle` file):

    compile 'io.vertx:vertx-config:3.5.0'
    compile 'io.vertx:vertx-config-hocon:3.5.0'

#### Configuring the store to use HOCON

Once added to your classpath or dependencies, you need to configure the `ConfigRetriever` to use this format:

    def store = [
      type:"file",
      format:"hocon",
      config:[
        path:"my-config.conf"
      ]
    ]

    def retriever = ConfigRetriever.create(vertx, [
      stores:[
        store
      ]
    ])

You just need to set `format` to `hocon`.
