=head1 NAME

CPANPLUS::Module - CPAN module objects for CPANPLUS

=head1 SYNOPSIS

### get a module object from the CPANPLUS::Backend object
    my $mod = $cb->module_tree('Some::Module');

### accessors
    $mod->version;
    $mod->package;

### methods
    $mod->fetch;
    $mod->extract;
    $mod->install;

=head1 DESCRIPTION

C<CPANPLUS::Module> creates objects from the information in the
source files. These can then be used to query and perform actions
on, like fetching or installing.

These objects should only be created internally. For C<fake> objects,
there's the C<CPANPLUS::Module::Fake> class. To obtain a module object
consult the C<CPANPLUS::Backend> documentation.

=head1 CLASS METHODS

=head2 accessors ()

Returns a list of all accessor methods to the object

=cut

### *name is an alias, include it explicitly
sub accessors { return ('name', keys %$tmpl) };

=head1 ACCESSORS

An objects of this class has the following accessors:

=over 4

=item name

Name of the module.

=item module

Name of the module.

=item version

Version of the module. Defaults to '0.0' if none was provided.

=item path

Extended path on the mirror.

=item comment

Any comment about the module -- largely unused.

=item package

The name of the package.

=item description

Description of the module -- only registered modules have this.

=item dslip

The five character dslip string, that represents meta-data of the
module -- again, only registered modules have this.

=cut

sub dslip {
    my $self    = shift;

### if this module has relevant dslip info, return it
    return $self->_dslip if $self->_dslip ne EMPTY_DSLIP;

### if not, look at other modules in the same package,
    ### see if *they* have any dslip info
    for my $mod ( $self->contains ) {
        return $mod->_dslip if $mod->_dslip ne EMPTY_DSLIP;
    }

### ok, really no dslip info found, return the default
    return EMPTY_DSLIP;
}

=pod

=item status

The C<CPANPLUS::Module::Status> object associated with this object.
(see below).

=item author

The C<CPANPLUS::Module::Author> object associated with this object.

=item parent

The C<CPANPLUS::Internals> object that spawned this module object.

=back

=cut

### Alias ->name to ->module, for human beings.
*name = *module;

sub parent {
    my $self = shift;
    my $obj  = CPANPLUS::Internals->_retrieve_id( $self->_id );

return $obj;
}

=head1 STATUS ACCESSORS

C<CPANPLUS> caches a lot of results from method calls and saves data
it collected along the road for later reuse.

C<CPANPLUS> uses this internally, but it is also available for the end
user. You can get a status object by calling:

$modobj->status

You can then query the object as follows:

=over 4

=item installer_type

The installer type used for this distribution. Will be one of
'makemaker' or 'build'. This determines whether C<CPANPLUS::Dist::MM>
or C<CPANPLUS::Dist::Build> will be used to build this distribution.

=item dist_cpan

The dist object used to do the CPAN-side of the installation. Either
a C<CPANPLUS::Dist::MM> or C<CPANPLUS::Dist::Build> object.

=item dist

The custom dist object used to do the operating specific side of the
installation, if you've chosen to use this. For example, if you've
chosen to install using the C<ports> format, this may be a
C<CPANPLUS::Dist::Ports> object.

Undefined if you didn't specify a separate format to install through.

=item prereqs | requires

A hashref of prereqs this distribution was found to have. Will look
something like this:

{ Carp  => 0.01, strict => 0 }

Might be undefined if the distribution didn't have any prerequisites.

=item configure_requires

Like prereqs, but these are necessary to be installed before the
build process can even begin.

=item signature

Flag indicating, if a signature check was done, whether it was OK or
not.

=item extract

The directory this distribution was extracted to.

=item fetch

The location this distribution was fetched to.

=item readme

The text of this distributions README file.

=item uninstall

Flag indicating if an uninstall call was done successfully.

=item created

Flag indicating if the C<create> call to your dist object was done
successfully.

=item installed

Flag indicating if the C<install> call to your dist object was done
successfully.

=item checksums

The location of this distributions CHECKSUMS file.

=item checksum_ok

Flag indicating if the checksums check was done successfully.

=item checksum_value

The checksum value this distribution is expected to have

=back

=head1 METHODS

=head2 $self = CPANPLUS::Module->new( OPTIONS )

This method returns a C<CPANPLUS::Module> object. Normal users
should never call this method directly, but instead use the
C<CPANPLUS::Backend> to obtain module objects.

This example illustrates a C<new()> call with all required arguments:

CPANPLUS::Module->new(
            module  => 'Foo',
            path    => 'authors/id/A/AA/AAA',
            package => 'Foo-1.0.tgz',
            author  => $author_object,
            _id     => INTERNALS_OBJECT_ID,
        );

Every accessor is also a valid option to pass to C<new>.

Returns a module object on success and false on failure.

=cut

sub new {
    my($class, %hash) = @_;

### don't check the template for sanity
    ### -- we know it's good and saves a lot of performance
    local $Params::Check::SANITY_CHECK_TEMPLATE = 0;

my $object  = check( $tmpl, \%hash ) or return;

bless $object, $class;

return $object;
}

### only create status objects when they're actually asked for
sub status {
    my $self = shift;
    return $self->_status if $self->_status;

my $acc = Object::Accessor->new;
    $acc->mk_accessors( qw[ installer_type dist_cpan dist prereqs
                            signature extract fetch readme uninstall
                            created installed prepared checksums files
                            checksum_ok checksum_value _fetch_from
                            configure_requires
                        ] );

### create an alias from 'requires' to 'prereqs', so it's more in
    ### line with 'configure_requires';
    $acc->mk_aliases( requires => 'prereqs' );

$self->_status( $acc );

return $self->_status;
}

### flush the cache of this object ###
sub _flush {
    my $self = shift;
    $self->status->mk_flush;
    return 1;
}

=head2 $mod->package_name( [$package_string] )

Returns the name of the package a module is in. For C<Acme::Bleach>
that might be C<Acme-Bleach>.

=head2 $mod->package_version( [$package_string] )

Returns the version of the package a module is in. For a module
in the package C<Acme-Bleach-1.1.tar.gz> this would be C<1.1>.

=head2 $mod->package_extension( [$package_string] )

Returns the suffix added by the compression method of a package a
certain module is in. For a module in C<Acme-Bleach-1.1.tar.gz>, this
would be C<tar.gz>.

=head2 $mod->package_is_perl_core

Returns a boolean indicating of the package a particular module is in,
is actually a core perl distribution.

=head2 $mod->module_is_supplied_with_perl_core( [version => $]] )

Returns a boolean indicating whether C<ANY VERSION> of this module
was supplied with the current running perl's core package.

=head2 $mod->is_bundle

Returns a boolean indicating if the module you are looking at, is
actually a bundle. Bundles are identified as modules whose name starts
with C<Bundle::>.

=head2 $mod->is_autobundle;

Returns a boolean indicating if the module you are looking at, is
actually an autobundle as generated by C<< $cb->autobundle >>.

=head2 $mod->is_third_party

Returns a boolean indicating whether the package is a known third-party
module (i.e. it's not provided by the standard Perl distribution and
is not available on the CPAN, but on a third party software provider).
See L<Module::ThirdParty> for more details.

=head2 $mod->third_party_information

Returns a reference to a hash with more information about a third-party
module. See the documentation about C<module_information()> in
L<Module::ThirdParty> for more details.

Installs the current module. This includes fetching it and extracting
it, if this hasn't been done yet, as well as creating a distribution
object for it.

This means you can pass it more arguments than described above, which

Returns a list of module objects that represent the modules also
present in the package of this module.

This function queries the CPAN testers database at

objects, module names or distributions.

Look at L<CPANPLUS::Internals::Report::_query_report()> for details on
the options you can pass and the return value to expect.

=head2 $bool = $self->uninstall([type => [all|man|prog])

This function uninstalls the specified module object.

You can install 2 types of files, either C<man> pages or C<prog>ram
files. Alternately you can specify C<all> to uninstall both (which
is the default).

Returns true on success and false on failure.

Do note that this does an uninstall via the so-called C<.packlist>,
so if you used a module installer like say, C<ports> or C<apt>, you
should not use this, but use your package manager instead.
