Subject [jira] Commented: (CLI-99) [cli] separate definition and values

Brian Egge commented on CLI-99:
-------------------------------

I agree w/ Andrew.  This is a won't fix in 1.x, and is fixed in 2.x.  In 2.x you have an instance
specific CommandLine object which holds the value of the parse.  This also makes unit testing
a lot easier as you don't have to clear the options after each parse.

> right now Option holds both configuration parameters - that say how to parese,
> and values - the result of parsing.
> this isn't very robust if options are used at places other than main(). for
> example, if some server application wants a cli interface (e.g., through a tcp
> connection), then the best approach for it would be to have a static variable
> with the options configuration and give it to the parser each time. with the
> current code, the Options object needs to be recreated every time.
> also, iterating over Options.getOptions() is cumbersome because some options may
> actually belong to an option group. it would be helpfull if Options.getOption
> would return a collection containing Option and OptionGroup, then the user can
> iterate over it, and with a simple 'instanceof' know what type it is, and then
> handle it.
