Configgle

Small Java too to make it easier to read user input via a proxy mechanism.

Examples

/* TestQuestions.java */
public interface TestQuestions {
    @Question("How old are you?")
    int age();

    @Question("Favourite colour?")
    String color();
}

TestQuestions questions = Configgle.get(TestQuestions.class);

int age = questions.age();

System.out.println("Okay great, now...");
String color = questions.color();

System.out.println("Lots of " + age + " year-olds like the color " + color + "!");

Yields this standard output and input:

How old are you?: 23
Okay great, now...
Favourite colour?: Blue
Lots of 23 year-olds like the color Blue!

Guide

First, create your interface class:

interface MyQuestions {
}

Define a method, annotated with @Question and a human readable message as the value:

@Question("Favourite color")
String color();
}

Create an instance through the utility method:

MyQuestions questioner = Configgle.get(MyQuestions.class);

You can now interrogate the resulting object using:

String color = questioner.color();

The user will be prompted for each new question.

Asking the same question twice will only prompt the user once, this is done intentionally through a caching mechanism.
