Console eases the creation of beautiful and testable command line interfaces. It is a port from Symfony2's Console component
The Application object manages the command-line application:
import org.nanocom.console.Application;
console = new Application();
console.run();
The run() method parses the arguments and options passed on the command
line and executes the right command.
Registering a new command can easily be done via the register() method,
which returns a Command instance:
import org.nanocom.console.Input.InputInterface;
import org.nanocom.console.Input.InputArgument;
import org.nanocom.console.Input.InputOption;
import org.nanocom.console.Output.OutputInterface;
console
.register("ls")
.setDefinition(Arrays.asList(
new InputArgument('dir', InputArgument.REQUIRED, "Directory name"),
))
.setDescription("Displays the files in the given directory")
.setCode(new Executable() {
@Override
protected int execute(InputInterface input, OutputInterface output);
String dir = input.getArgument("dir");
output.writeln(String.format("Dir listing for <info>%s</info>", dir));
return 0;
}
})
;
You can also register new commands via classes.
The component provides a lot of features like output coloring, input and output abstractions (so that you can easily unit-test your commands), validation, automatic help messages, ...
