[jira] [Commented] (CLI-246) GnuParser removes first character from
longer argument containing single character option
[ https://issues.apache.org/jira/browse/CLI-246?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14135535#comment-14135535 ]
Emmanuel Bourg commented on CLI-246:
------------------------------------
Thank you for the report, could you try with the DefaultParser on the trunk and see if it works please?

>
> Key: CLI-246
> URL: https://issues.apache.org/jira/browse/CLI-246
> Project: Commons CLI
> Issue Type: Bug
> Components: CLI-1.x
> Affects Versions: 1.2
> Environment: Windows 64-bit
> Reporter: Pierre-Luc Lacroix
> Priority: Minor
>
> Title might be hard to understand, but basically:
> Arguments:
> String [] cli = {"-cc", "-ccc", "-c"};
> Options:
> Options opts = new Options();
> opts.addOption(OptionBuilder.create("cc"));
> opts.addOption(OptionBuilder.create("c"));
> As you can see, "-ccc" is an extra unrecognized argument.
> When you try to parse it:
> CommandLineParser parser = new GnuParser();
> CommandLine line = parser.parse(opts, cli, true);
> Content on line:
> args: [cc, -c]
> line: [[ option: cc :: null ], [ option: c :: null ]]
> I would expect:
> args: [-ccc]
> line: [[ option: cc :: null ], [ option: c :: null ]]
> Wrote a few unit tests (3rd one fails):
> {code:title=UnitTest.java|borderStyle=solid}

>
>
> CommandLineParser parser = new GnuParser();
> CommandLine line = parser.parse(opts, cli);

> Assert.fail("Extra argument found: " + line.getArgList().get(0));
