A simple bootstrap for commandline java applications
See the com.cakemanny.app.Example class for an idea of how to use:
import java.io.File;
public class Example implements App {
String poop = App.option("poop", "Hi", "The required poop. A long description message");
int port = App.option("port", 8912, "The port to listen on");
File file = App.option("file", new File("."), "The file ya know!");
public void main() {
System.out.println("hello");
System.out.println("port=" + port);
System.out.println("poop=" + poop);
System.out.println("file=" + file);
System.out.println("file.exists()=" + file.exists());
}
}Then run with
> java -cp ".:Command.jar" -Dprog.name=Example \
-Dprog.className=com.cakemanny.app.Example \
com.cakemanny.app.App
- Idea for improvement: add a quick classpath scan for implementor of App to save having to pass the full class name as an option
