Subject [jira] [Commented] (CLI-179) Needs "standalone" options that can be used even if required options are not set
Date Wed, 19 Jul 2017 09:38:00 GMT

    [ https://issues.apache.org/jira/browse/CLI-179?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16092863#comment-16092863

Emmanuel Bourg commented on CLI-179:
------------------------------------

[~iweiss] That's only the first pass. If the parsing fails because --help and --version are
missing, you catch the exception and run a second pass with the other options.

> it is currently impossible to have options like "help" or "version" if we also have some
required options. The parsing results in an error "Missing parameters".
> But for an "help" or "version" option, it would be usefull to display the wanted information,
even if required options are not set.
