Mandatory options?

[deric]

Is it possible to specify an option which will be required in order to run command?

There's not an automatic way to do that, but you could use something like this:

command :bar do |c|
  c.option '--prefix STRING', String, 'Adds a prefix to bar'
  c.action do |args, options|
    raise ArgumentError.new("Prefix is required!") unless options.prefix
    # ... normal command stuff here ...
  end
end

Ok, thanks. It would be nice to have something like this:

command :bar do |c|
  c.option '--prefix STRING', String, 'Adds a prefix to bar', :mandatory => true
   # ...
end

When mandatory option would be missing, usage will be printed.

I'd like to see an easy way to have mandatory options as well.

Is there any update on this ?

Pull requests are welcome! I think this would not be too tricky to implement. In the meantime there's always the workaround I posted above.
