./script.pl -f=4    # $foo => 4

# in script.pl
opts my $foo => { 'Int', required => 1 },
     my $bar => 'Int';

./script.pl --foo=3 --bar=4 # $foo => 3, $bar => 4
./script.pl --foo=4         # $foo => 4, $bar => undef
./script.pl --bar=4         # error!

# in script.pl
opts my $foo => {isa => 'Int', default => 3},

./script.pl --foo=4     # $foo => 4
./script.pl             # $foo => 3

# in script.pl
opts my $foo => { isa => 'Int', alias => 'x|bar' };

./script.pl --foo=4 # $foo => 4
./script.pl --bar=4 # $foo => 4

DESCRIPTION

opts is DSL for command line option.

Options

isa
   define option value type. see $opts::TYPE_CONSTRAINT.
   if you need more type, see opts::coerce

required
  define option value is required.

default
  define options default value. If passed a coderef, it
  will be executed if no value is provided on the command line.

alias
  define option param's alias.

TYPES

Str

Int

Num

Bool

ArrayRef

HashRef

Multiple

This subtype is based off of ArrayRef. It will attempt to split any values passed on the command line on a comma: that is,

[ "one", "two,three" ]

will become

[ "one", "two", "three" ].

opts::coerce

opts::coerce NewType => SrcType => generater;

ex) 
  opts::coerce DateTime => 'Str' => sub { DateTime->strptime("%Y-%m-%d", shift) };

  opts my $date => 'DateTime';

  $date->ymd; # => yyyy/mm/dd
