Kotlin Json DSL

Dependecies

Step 1. Add the JitPack repository to your build file

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

Step 2. Add the dependency

dependencies {
  compile 'com.github.fcannizzaro:kson:1.0.3'
}

Usage

val data = json {

  entry("key", "value")

  entry("array") {
    val items = (1..4).map { "item $it" }.reversed()
    items
  }

  entry("array-fast", array("fast 0", "fast 1"))

  entry("another-key", "another-value")

}

println(data.toString(4))

JSON Result

{
  "array-fast": ["fast 0", "fast 1"],
  "array": ["item 4", "item 3", "item 2", "item 1"],
  "another-key": "another-value",
  "key": "value"
}

[ ] Operator

{
  "first": {
    "second" : {
      "key" : "value"
    }
  }
}

You can access "key" by simply doing:

val obj : JSONObject = /* already built */
val key = obj["first"]["second"]["key"] as String
