Subject [jira] Commented: (CLI-138) No '--' option for terminating options processing
Date Thu, 26 Jul 2007 06:49:31 GMT

    [ https://issues.apache.org/jira/browse/CLI-138?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12515524

Brian Egge commented on CLI-138:
--------------------------------

Many Unix programs have the -- option, such as Ruby & Perl.  I think it's a good to have,
but I have to disagree that's it's a bug.

You could 'preprocess' the args and use CLI 1.1, or you could look at using the 2.0 branch.
 It would be good to get some development on the 2.0 branch.  There are a number of things
the 1.x branch doesn't do, but would be really useful to have.

For example, I usually have a help & version option.  If either of these options are present,
then nothing else should be, and 'required' arguments become 'not required'.  2.0 has build
in handling for this situation.  What I do now though, is process the arguments twice.  Once
for help/version, and if neither are present, then I do the regular parse.

> It appears that neither 1.0 not 1.1 have a '--' option as the 'end processing options'
option.  This is immensely useful to allow parameter that are not options that start with
a hyphen.  grep for example does this.  I think it is a bug rather than an enhancement request,
I think Commons CLI should support '--' option.
