[jira] [Created] (CLI-216) Optional support for concatenated option
in the DefaultParser
Optional support for concatenated option in the DefaultParser
-------------------------------------------------------------
Key: CLI-216
URL: https://issues.apache.org/jira/browse/CLI-216
Project: Commons CLI
Issue Type: Improvement
Components: Parser
Affects Versions: 1.3
Reporter: Emmanuel Bourg
Fix For: 1.3
DefaultParser supports the concatenated options of the PosixParser (i.e tar -zxvf), but in many cases this behavior is not desirable. This should be made optional.

----------------------------------
Just to get an impression on this issue:
* In which cases do you not want such a behavior?
* Where could it be disabled, during options building or during parsing?

Emmanuel Bourg commented on CLI-216:
------------------------------------
It's not necessarily related to CLI-217. If there was a "ver" long option, and "v", "e", "r" short options, there is still an ambiguity if "-ver" appears on the command line.

----------------------------------
I thought of a use-case, but so far could not find one.
Look at the test-cases below. They run perfect with Default- and Posix-Parser.
{code}
public void testBursting2() throws Exception
{
String[] args = new String[]{"-zxvf", "file1", "-xzvf", "file2"};
Options opts = new Options();
opts.addOption(OptionBuilder.create("x"));
opts.addOption(OptionBuilder.create("v"));
opts.addOption(OptionBuilder.create("z"));
opts.addOption(OptionBuilder.hasArg().create("f"));
opts.addOption(OptionBuilder.hasArg().withLongOpt("zxvf").create());
CommandLine cl = parser.parse(opts, args);
assertTrue("Confirm -zxvf is set", cl.hasOption("zxvf"));
assertEquals("Confirm arg of -zxvf", "file1" , cl.getOptionValue("zxvf"));
assertTrue("Confirm -x is set", cl.hasOption("x"));
assertTrue("Confirm -v is set", cl.hasOption("v"));
assertTrue("Confirm -z is set", cl.hasOption("z"));
assertTrue("Confirm -f is set", cl.hasOption("f"));
assertEquals("Confirm arg of -f", "file2" , cl.getOptionValue("f"));
}
public void testBursting3() throws Exception
{
String[] args = new String[]{"-zx", "file1", "-zvxf", "file2"};
Options opts = new Options();
opts.addOption(OptionBuilder.create("x"));
opts.addOption(OptionBuilder.create("v"));
opts.addOption(OptionBuilder.create("z"));
opts.addOption(OptionBuilder.hasArg().create("f"));
opts.addOption(OptionBuilder.hasArg().withLongOpt("zxvf").create());
CommandLine cl = parser.parse(opts, args);
assertTrue("Confirm -zxvf is set", cl.hasOption("zxvf"));
assertEquals("Confirm arg of -zxvf", "file1" , cl.getOptionValue("zxvf"));
assertTrue("Confirm -x is set", cl.hasOption("x"));
assertTrue("Confirm -v is set", cl.hasOption("v"));
assertTrue("Confirm -z is set", cl.hasOption("z"));
assertTrue("Confirm -f is set", cl.hasOption("f"));
assertEquals("Confirm arg of -f", "file2" , cl.getOptionValue("f"));
}

------------------------------------
I was thinking at something like v, e, r short options, and a 'version' long option. On typing -ver there is an ambiguity.

Hartmut Lang commented on CLI-216:
----------------------------------
In this example i think -ver will be the partial matched 'version' long-option.
So you expect to be the three short option 'v,e,r' , do you?
So this is more related to CLI-217, turn of the partial matching, right?

Emmanuel Bourg commented on CLI-216:
------------------------------------
It would be disabled on the parser, the definition of the options is independent.
I don't have a use case in mind for disabling this behavior. I guess one can imagine it conflicts with the matching of a long option.
