[root@sigma dogtag]# pki group-add

Error: Missing required option: description
usage: group-add <Group ID> [OPTIONS...]
    --description <description>   Description
    --help                        Show help options

Missing is not reported.

As discussed on IRC, this would more than likely require a change to the way that the command-line is currently parsed by the CLI tools (possibly using some classes other than the Apache Commons CLI Options/Option classes).

Currently, the following procedures are followed:

check for "--help" on the command-line, and if present display command usage
parse the lines, failing with an exception on any missing required "option" where an option is of the form "--
check for the valid number of "arguments" (e. g. - )

proposed milestone: 10.3

It might be possible to fix this by making the options optional during parsing, then checking for required options manually after that.

So the steps are:

create all options (everything is optional)
parse the command line (to detect illegal options)
check for --help
check for number of arguments
process the command while checking for missing/extraneous options

What happens if you specify the "description", but only leave out the "Group ID"? I'd like to see the actual message.

Replying to [comment:4 nkinder]:

What happens if you specify the "description", but only leave out the "Group ID"? I'd like to see the actual message.

If a "--description " were specified, the following message would be returned:

Error: No Group ID specified.
usage: group-add <Group ID> [OPTIONS...]
    --description <description>   Description
    --help                        Show help options

As explained above, this behavior is exactly as described above.

However, rather than closing this ticket, I am going to re-title it and move it to 10.4.
