Type Members

1. abstract class CmdOpts[T] extends AnyRef

   

   This class implements a simple but type-safe command-line option parser.

   This class implements a simple but type-safe command-line option parser.

   You will generally use this by declaring an object that extends CmdOpts and passing in args (the array of cmd-line String arguments).

   You then ask for the specific options by calling 'opt' with the String for the option name, and a function that takes the next n Strings and returns a thing of the type you want. If the arguments are found they are passed to the function and the result is returned inside a Some, if they cannot be found or an exception is thrown from the function, a None is returned.

   Validation error messages can be specified by implementing the validate method.

   Usage and Version messages can be specified by implementing the usage and version methods respectively.
