Hi PerlMonks,

I need to parse dynamic varying command line strings and create a hash of the syntax.

An example of the string is below (there are more variations to this with different syntax) :

dfpm dataset add -D -N <node-name> <data-set-name-or-id> { <volume-name-or-id> | <qtree-name-or-id> | <ossv-dir-name-or-id> | <storage-system-name-or-id> | <host-name-or-id> } ...

A brief about the syntax in the string :

[] - optional parameters

<> - mandatory parameters

{|} - or parameters

The hash i need to build from the string mentioned above is below : 

$dataset_add = {
              'mandatory' => [
                                {
                                 'param1' => '$data-set-name-or-id',

                                }

                             ],
              'optional' => [
                                {
                                  'switch' => '-D',
                                  'value' => ''
                                },
                                {
                                  'switch' => '-N',
                                  'value' => '$node-name'
                                },
                                {
                                  'switch' => '',
                                  'value' => [$volume-name-or-id,$volu
+me-name-or-id,$ossv-dir-name-or-id,$storage-system-name-or-id,$host-n
+ame-or-id    ]
                                },
                              ]
                        }

Looking for direction to accomplish the same.

Thanks in Advance!
