NAME

MooseX::Scaffold - Template metaprogramming with Moose

VERSION

Version 0.04

SYNOPSIS

package MyScaffolder;

use MooseX::Scaffold;

MooseX::Scaffold->setup_scaffolding_import;

sub SCAFFOLD {
    my $class = shift; my %given = @_;

    $class->has($given{kind} => is => 'ro', isa => 'Int', required => 1);

    # Using MooseX::ClassAttribute
    $class->class_has(kind => is => 'ro', isa => 'Str', default => $given{kind});
}

package MyAppleClass;

use Moose;
use MooseX::ClassAttribute;
use MyScaffolder kind => 'apple';

package MyBananaClass;

use Moose;
use MooseX::ClassAttribute;
use MyScaffolder kind => 'banana';

# ... meanwhile, back at the Batcave ...

use MyAppleClass;
use MyBananaClass;

my $apple = MyAppleClass->new(apple => 1);
my $banana = MyBananaClass->new(banana => 2);

DESCRIPTION

MooseX::Scaffold is a tool for creating or augmenting Moose classes on-the-fly.

Scaffolding can be triggered when a use is executed (any import arguments are passed to the scaffold subroutine) or you can explicitly call MooseX::Scaffold->scaffold with the scaffolding subroutine and the package name for the class.

Depending on what you're trying to do, MooseX::Scaffold can behave in three different ways (Assume My::Class is the class you're trying to create/augment):

load_and_scaffold (scaffold)   - Attempt to require My::Class from My/Class.pm or do Moose::Meta::Class->create('My::Class')
                                 to make the package on-the-fly. Scaffold the result.

load_or_scaffold (load)        - Attempt to require My::Class from My/Class.pm and stop if that works. If no My/Class.pm is
                                 found in @INC, then make a Moose class on-the-fly and scaffold it.
                                 This option can be used to create a default class if one isn't found.

scaffold_without_load          - Don't attempt to require My::Class, just create it on-the-fly and scaffold it.

METHODS

MooseX::Scaffold->scaffold( ... )

Scaffold a class by either loading it or creating it. You can pass through the following:

scaffolder              
scaffolding_package     This should be either a subroutine (sub { ... }) or a package name. If a package name
                        is given, then the package should contain a subroutine called SCAFFOLD

class
class_package           The package name of resulting class

load_or_scaffold        Attempt to load $class_package first and do nothing successful. Otherwise create
                        $class_package and scaffold it

scaffold_without_load   Scaffold $class_package without attempting to load it first. Does not have
                        any effect if $class_package has been loaded already

no_class_attribute      Set this to 1 to disable applying the MooseX::ClassAttribute meta-role
                        on class creation. This has no effect if the class is loaded (If you
                        want class_has with a loaded class, make sure to 'use MooseX::ClassAttribute')

MooseX::Scaffold->load_and_scaffold( ... )

An alias for ->scaffold

MooseX::Scaffold->load_or_scaffold( ... )

An alias for ->scaffold with load_or_scaffold set to 1

MooseX::Scaffold->load( ... )

An alias for ->load_or_scaffold

MooseX::Scaffold->scaffold_without_load( ... )

An alias for ->scaffold with scaffold_without_load set to 1

MooseX::Scaffold->build_scaffolding_import( ... )

Return an anonymous subroutine suitable for use an an import function

Anything passable to ->scaffold is fair game. In addition:

scaffolder      This will default to the package of caller() if unspecified

chain_import    An (optional) subroutine that will goto'd after scaffolding is complete

MooseX::Scaffold->setup_scaffolding_import( ... )

Install an import subroutine. By default, caller() will be used for the exporting package, but another may be specified.

Anything passable to ->build_scaffolding_import is fair game. In addition:

exporter
exporting_package   The package that will house the import subroutine (the scaffolding will trigger
                    when the package is used or imported)

MooseX::Scaffold->load_package( $package )

MooseX::Scaffold->load_class( $class )

A convenience method that will attempt to require $package or $class if not already loaded

Essentially does ...

eval "require $package;" or die $@

... but uses Class::Inspector to check for $package existence first (%INC is not trustworthy)
