%S for Strings
==============
When emitting code that includes string literals, we can use **`%S`** to emit a **string**, complete
with wrapping quotation marks and escaping. Here's a program that emits 3 methods, each of which
returns its own name:
```kotlin
fun main(args: Array<String>) {
val helloWorld = TypeSpec.classBuilder("HelloWorld")
.addFunction(whatsMyNameYo("slimShady"))
.addFunction(whatsMyNameYo("eminem"))
.addFunction(whatsMyNameYo("marshallMathers"))
.build()
val kotlinFile = FileSpec.builder("com.example.helloworld", "HelloWorld")
.addType(helloWorld)
.build()
kotlinFile.writeTo(System.out)
}
private fun whatsMyNameYo(name: String): FunSpec {
return FunSpec.builder(name)
.returns(String::class)
.addStatement("return %S", name)
.build()
}
```
In this case, using `%S` gives us quotation marks:
```kotlin
class HelloWorld {
fun slimShady(): String = "slimShady"
fun eminem(): String = "eminem"
fun marshallMathers(): String = "marshallMathers"
}
```
