Subject [jira] [Commented] (CLI-255) DefaultParser, option with long name and single dash, unlimited arguments
Date Fri, 17 Jun 2016 11:17:05 GMT

Jason Newell commented on CLI-255:
----------------------------------

I've a similar issue but basically DefaultParser doesn't work with a single dash where the
option name exceeds one character in length so -a is fine but -ab doesn't work. I've been
exercising this with a JUnit test.

    @Test public void CliTest() throws ArgumentException 
    {
    	s_clsLogger.info("MainWithWrongNumArgsTest()");
    	try
    	{
    		String strCmk = "xr";
    		Options s_clsOptions = new Options();
    		
    		Option clsOptionTstp = Option.builder(strCmk)
    										   .valueSeparator('=')
    										   .type(String.class)
    										   .required()
    										   .hasArg()
    										   .argName("TestCommandPath=value")
    										   .desc("A test path")
    										   .build();
    		
    		s_clsOptions.addOption(clsOptionTstp);

    		String[] astrCli = new String[]{String.format("-%s=cd", strCmk)};
    		CommandLineParser s_clsClParser = new DefaultParser();
    		CommandLine clsCommandLine = s_clsClParser.parse(s_clsOptions, astrCli, true);
    		
    		if(clsCommandLine.hasOption(strCmk))
    		{
    			String strOptionValue = clsCommandLine.getOptionValue(strCmk);
    			assertEquals(strOptionValue,"cd");
    		}
    		else
    		{
    			fail();
    		}
    	}
    	catch (Exception e)
		{
    		s_clsLogger.error(e);
			fail(e.toString());
		}
    	finally
    	{	
    	}
    }

>                 URL: https://issues.apache.org/jira/browse/CLI-255
>             Project: Commons CLI
>          Issue Type: Bug
>          Components: Parser
>    Affects Versions: 1.3, 1.3.1
>            Reporter: Alexander Prishchepov
>            Priority: Minor
>
> If I have options with long name and single dash, DefaultParser does not recognize them
after a list of unlimited arguments.
> Here is the test case:
> {code:java}
>     public void testUnlimitedArgs() throws Exception
>     {
>         String[] args = new String[] {"-unlimitedOne", "one", "two", "-unlimitedTwo",
"alpha"};
>         Options options = new Options();
>         options.addOption(Option.builder("unlimitedOne").hasArgs().build());
>         options.addOption(Option.builder("unlimitedTwo").hasArgs().build());
>         CommandLine cl = parser.parse(options, args);
>         assertTrue("Confirm -unlimitedOne is set", cl.hasOption("unlimitedOne"));
>         assertEquals("number of arg for -unlimitedOne", 2, cl.getOptionValues("unlimitedOne").length);
>         assertTrue("Confirm -unlimitedTwo is set", cl.hasOption("unlimitedTwo"));
>         assertEquals("number of arg for -unlimitedTwo", 1, cl.getOptionValues("unlimitedTwo").length);
>     }
> {code}
