Rapture I/O JSON extraction example

json.scala

import rapture.io._

// Let's parse some JSON
val src: Json = Json.parse("""
{
  "foo": "Hello world",
  "bar": {
    "baz": 42
  }
}
""")

// This is the same as the JSON string literal:
val src: Json = json"""
{
  "foo": "Hello world",
  "bar": {
    "baz": 42
  }
}
"""

// We can now access the value bar.baz
val x: Json = src.bar.baz

// And get it as an integer
val y: Int = x.get[Int]

// Alternatively, we can use an extractor to get the values we want:
val json""" { "bar": { "baz": $x }, "foo": $z }""" = src

// Now x = 42 and z = "Hello world".
