Example
Here is a full Hello world example
class Hello {
public static void main(String[] args) {
Hello hello = new Hello();
CLISpecification cli = new CLISpecification(System.out);
cli.add('n', "name", "Your name", CLIHandlers.string(hello.name));
cli.add("prefix", "Prefix for your name, i. e. Mr, Mrs, Dr, Sir", CLIHandlers.string(hello.prefix));
try {
cli.run(args);
application.run();
} catch (CLIException ex) {
System.out.println(ex.getMessage());
System.out.println("usage: hello [OPTIONS]");
try {
cli.usage();
} catch (IOException ex1) {
ex1.printStackTrace(System.out);
}
} catch (IOException ex) {
ex.printStackTrace(System.out);
}
}
private Property<String> name = new Property<String>(null);
private Property<String> prefix = new Property<String>("Mr.");
private void run() {
System.out.println("Hello " + prefix.get() + " " + name.get());
}
}
When you compile it and run like
java -jar hello.jar -n John --prefix=Sir.
You'll get the following
Hello Sir. John
You can get usage-message like this:
java -jar hello.jar -h
You'll get the following answer
Unknown option -h
usage: hello [OPTIONS]
-n OPTION Your name
--name=OPTION Your name
--prefix=OPTION Prefix for your name, i. e. Mr, Mrs, Dr, Sir (default Mr.)
