Bug #15774

OptionParser doesn't accept Date options as stated in the docs

The documentation for OptionParser states that Date, Time and DateTime are supported types for automatic coertion, however, it raises an error if any of those types are provided to the "on" method: "unsupported argument type: Date".

Either the documentation is wrong or there's a bug in the implementation of OptionParser I guess.

Thanks for taking a look into this.

You need to require 'optparse/time' to use built-in Time conversion (it doesn't seem to be stated explicitly in the documentation, but it is demonstrated throughout the examples) and you need to require 'optparse/date' to use Date or DateTime conversions. Or you can define custom conversions.

Oh, thanks, I wasn't aware of that. Now that you said I re-read the documentation and found the instructions to use those built-in conversions. Thanks. This ticket can be closed. I'm not allowed to close it myself.
