README
optional is a command line option parser and library.
YOU WRITE:
object MyAwesomeCommandLineTool extends optional.Application {
// for instance...
def main(count: Option[Int], file: Option[java.io.File], arg1: String) {
[...]
}
}
THEN YOU DO:
scala MyAwesomeCommandLineTool --count 5 quux
AND YOUR MAIN METHOD WILL BE INVOKED SUCH THAT:
count = Some(5)
file = None
arg1 = quux
See the example programs for many more features.
HOW IT WORKS:
Reflection, man.
