=head1 NAME

MooseX::Types::Path::Class - A Path::Class type library for Moose


=head1 SYNOPSIS

  package MyClass;
  use Moose;
  use MooseX::Types::Path::Class;
  with 'MooseX::Getopt';  # optional

  has 'dir' => (
      is       => 'ro',
      isa      => 'Path::Class::Dir',
      required => 1,
      coerce   => 1,
  );

  has 'file' => (
      is       => 'ro',
      isa      => 'Path::Class::File',
      required => 1,
      coerce   => 1,
  );

  # these attributes are coerced to the
  # appropriate Path::Class objects
  MyClass->new( dir => '/some/directory/', file => '/some/file' );


=head1 DESCRIPTION

MooseX::Types::Path::Class creates common L<Moose> types,
coercions and option specifications useful for dealing
with L<Path::Class> objects as L<Moose> attributes.

Coercions (see L<Moose::Util::TypeConstraints>) are made
from both 'Str' and 'ArrayRef' to both L<Path::Class::Dir> and
L<Path::Class::File> objects.  If you have L<MooseX::Getopt> installed,
the Getopt option type ("=s") will be added for both
L<Path::Class::Dir> and L<Path::Class::File>.


=head1 EXPORTS

None of these are exported by default.  They are provided via
L<MooseX::Types>.

=over

=item Dir, File

These exports can be used instead of the full class names.  Example:

  package MyClass;
  use Moose;
  use MooseX::Types::Path::Class qw(Dir File);

  has 'dir' => (
      is       => 'ro',
      isa      => Dir,
      required => 1,
      coerce   => 1,
  );

  has 'file' => (
      is       => 'ro',
      isa      => File,
      required => 1,
      coerce   => 1,
  );

Note that there are no quotes around Dir or File.

=item is_Dir($value), is_File($value)

Returns true or false based on whether $value is a valid Dir or File.

=item to_Dir($value), to_File($value)

Attempts to coerce $value to a Dir or File.  Returns the coerced value
or false if the coercion failed.
