1JCommander 2========== 3 4This is an annotation based parameter parsing framework for Java. 5 6Here is a quick example: 7 8```java 9public class JCommanderTest { 10 @Parameter 11 public List<String> parameters = Lists.newArrayList(); 12 13 @Parameter(names = { "-log", "-verbose" }, description = "Level of verbosity") 14 public Integer verbose = 1; 15 16 @Parameter(names = "-groups", description = "Comma-separated list of group names to be run") 17 public String groups; 18 19 @Parameter(names = "-debug", description = "Debug mode") 20 public boolean debug = false; 21 22 @DynamicParameter(names = "-D", description = "Dynamic parameters go here") 23 public Map<String, String> dynamicParams = new HashMap<String, String>(); 24 25} 26``` 27 28and how you use it: 29 30```java 31JCommanderTest jct = new JCommanderTest(); 32String[] argv = { "-log", "2", "-groups", "unit1,unit2,unit3", 33 "-debug", "-Doption=value", "a", "b", "c" }; 34new JCommander(jct, argv); 35 36Assert.assertEquals(2, jct.verbose.intValue()); 37Assert.assertEquals("unit1,unit2,unit3", jct.groups); 38Assert.assertEquals(true, jct.debug); 39Assert.assertEquals("value", jct.dynamicParams.get("option")); 40Assert.assertEquals(Arrays.asList("a", "b", "c"), jct.parameters); 41``` 42 43The full doc is available at http://beust.com/jcommander 44
