Command Line Parsing: Commons CLI alternatives?
JCommander sounds like a very simple and interesting approach to parsing command line arguments with annotations (from the creator of TestNG):
You annotate fields with descriptions of your options:
import com.beust.jcommander.Parameter;
public class JCommanderTest {
@Parameter
public List<String> parameters = Lists.newArrayList();
@Parameter(names = { "-log", "-verbose" }, description = "Level of verbosity")
public Integer verbose = 1;
@Parameter(names = "-groups", description = "Comma-separated list of group names to be run")
public String groups;
@Parameter(names = "-debug", description = "Debug mode")
public boolean debug = false;
}
and then you simply ask JCommander to parse:
JCommanderTest jct = new JCommanderTest();
String[] argv = { "-log", "2", "-groups", "unit", "a", "b", "c" };
new JCommander(jct, argv);
Assert.assertEquals(jct.verbose.intValue(), 2);
