%S or %C for Strings

If you want to emit code that includes string literals, you can use `%S` or `%C` to emit a string into the generation.

The programming language Dart allows the usage of strings with a double quotes `("")` and single quotes `('')`. There are no difference between both variants.

If you want to have a string with double quotes use the `%S` formatter and for single quotes the '%C' formatter.

In the following there is a small program that emits a unique string for each available string formatter:

fun main(args: Array<String>) {
    val mainClass = ClassSpec.builder("HelloWord")
            .function(getFunction("%S", "Dart")) // Uses double quotes
            .function(getFunction("%C", "Poet")) // Uses single quotes
            .build()

    val dartFile = DartFile.builder("hello_world")
            .type(mainClass)
            .build()
    dartFile.write(System.out) // Writes the code into the output stream
}

The generated code result is:

class HelloWord {

  String getDart() {
    return "Dart";
  }

  String getPoet() {
    return 'Poet';
  }
}
