## NAME
    oose - syntactic sugar to make Moose one-liners easier

## VERSION
    version 2.2200

## SYNOPSIS
      # create a Moose class on the fly ...
      perl -Moose=Foo -e 'has bar => ( is=>q[ro], default => q[baz] ); print Foo->new->bar' # prints baz

      # loads an existing class (Moose or non-Moose)
      # and re-"opens" the package definition to make
      # debugging/introspection easier
      perl -Moose=+[My::Class](https://www.chedong.com/phpMan.php/perldoc/My%3A%3AClass/markdown) -e 'print join ", " => __PACKAGE__->meta->get_method_list'

      # also loads [Moose::Util::TypeConstraints](https://www.chedong.com/phpMan.php/perldoc/Moose%3A%3AUtil%3A%3ATypeConstraints/markdown) to allow subtypes etc
      perl -Moose=Person -e'subtype q[ValidAge] => as q[Int] => where { $_ > 0 && $_ < 78 }; has => age ( isa => q[ValidAge], is => q[ro]); Person->new(age => 90)'

## DESCRIPTION
    oose.pm is a simple source filter that adds "package $name; use Moose; use
    [Moose::Util::TypeConstraints](https://www.chedong.com/phpMan.php/perldoc/Moose%3A%3AUtil%3A%3ATypeConstraints/markdown);" to the beginning of your script and was entirely created because
    typing "perl -e'package Foo; use Moose; ...'" was annoying me.

## INTERFACE
    oose provides exactly one method and it's automatically called by perl:

    import($package)
        Pass a package name to import to be used by the source filter. The package defaults to
        "Class" if none is given.

## DEPENDENCIES
    You will need [Filter::Simple](https://www.chedong.com/phpMan.php/perldoc/Filter%3A%3ASimple/markdown) and eventually Moose

## INCOMPATIBILITIES
    None reported. But it is a source filter and might have issues there.

## BUGS
    See "BUGS" in Moose for details on reporting bugs.
