Allows a programmer to easily add required switches to a Ruby app using the built-in OptionParser class.
To make a switch required simple add the symbol :required anywhere in the list of options like so:
opts.on("-f [foo]", String, :required, "Required option") do |option| @options[:foo] = option end
Then at the end of your OptionParser block add something like this:
if opts.missing_switches? puts opts.missing_switches puts opts exit end
You of course need to require the “pickled_optparse” gem but that's it. You don't need to require the opt_parse file because that's already handled for you.
For a complete usage example see the examples/example.rb file.
Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
