Thomas Neidhart commented on CLI-221:
-------------------------------------
I do not see this as a bug. The withValueSeparator option does not mean that
the arguments *must* be concatenated by this separator. It currently works only
as an optional splitting mechanism. Any (whitespace) separated tokens after the
option will be treated as its arguments.
> cli's with last option as list type values and have argument are not parsed
> correctly

> Key: CLI-221
> URL: https://issues.apache.org/jira/browse/CLI-221
> Project: Commons CLI
> Issue Type: Bug
> Components: Parser
> Affects Versions: 1.2
> Reporter: Gagan Jain
>
> I have set the value separator for an option to be comma (',').
> Consider the following cli:
> cli definition : cmd1 -o1 <comma separated values> a1
> command name: 'cmd1'
> options: 'o1' accpets list of values separated by ','
> arguments: 'a1' single valued argument
> {code}cmd1 -o1 o1v1,o1v2,o1v3 a1v1{code}
> GnuParser parses this the cli with o1 having values {o1v1, o1v2, o1v3, a1v1}
> instead of {o1v1,o1v2,o1v3}
> Bug seems to be in org.apache.commons.cli.Parser's class processArgs method.
> {code:java}
> public void processArgs(Option opt, ListIterator iter) throws
> ParseException
> {
> // loop until an option is found
> while (iter.hasNext())
> {
> String str = (String) iter.next();
> // found an Option, not an argument
> if (getOptions().hasOption(str) && str.startsWith("-"))
> {
> iter.previous();
> break;
> }
> // found a value
> try
> {
>
> opt.addValueForProcessing(Util.stripLeadingAndTrailingQuotes(str));
> }
> catch (RuntimeException exp)
> {
> iter.previous();
> break;
> }
> }
> if (opt.getValues() == null && !opt.hasOptionalArg())
> {
> throw new MissingArgumentException(opt);
> }
> }
> {code}
> In my opinion, if a value separator is defined for option, and is other than
> space (' '), loop should break immediately after one iteration.
> Correct me, if I am wrong in my understanding.
