I use GetoptLong but I miss something much shorter in usage like
GetoptLong in Perl. In Perl I could write
GetOptions(‘re_from=s’ => $re_from, ‘re_to=s’ => $re_to, ‘do’ =>
$do_do, ‘enum’ => $enum, ‘from=i’ => $from, ‘step=i’ => $step,
‘width=i’ => $width);
So in one line – or two – I set the possible arguments, their
types, assignment to variables and all the if-checking is done for me.
No need to write loop to check all parameters like in Ruby.
Is any package available which do similar thing for Ruby?
Thanks in advance, have a good day
