=head1 NAME

CPANPLUS::Dist::Build - CPANPLUS plugin to install packages that use Build.PL

=head1 SYNOPSIS

    my $build = CPANPLUS::Dist->new(
                                format  => 'CPANPLUS::Dist::Build',
                                module  => $modobj,
                            );
                            
    $build->prepare;    # runs Build.PL                            
    $build->create;     # runs build && build test
    $build->install;    # runs build install


=head1 DESCRIPTION

C<CPANPLUS::Dist::Build> is a distribution class for C<Module::Build>
related modules.
Using this package, you can create, install and uninstall perl
modules. It inherits from C<CPANPLUS::Dist>.

Normal users won't have to worry about the interface to this module,
as it functions transparently as a plug-in to C<CPANPLUS> and will 
just C<Do The Right Thing> when it's loaded.

=head1 ACCESSORS

=over 4

=item C<parent()>

Returns the C<CPANPLUS::Module> object that parented this object.

=item C<status()>

Returns the C<Object::Accessor> object that keeps the status for
this module.

=back

=head1 STATUS ACCESSORS

All accessors can be accessed as follows:
    $build->status->ACCESSOR

=over 4

=item C<build_pl ()>

Location of the Build file.
Set to 0 explicitly if something went wrong.

=item C<build ()>

BOOL indicating if the C<Build> command was successful.

=item C<test ()>

BOOL indicating if the C<Build test> command was successful.

=item C<prepared ()>

BOOL indicating if the C<prepare> call exited successfully
This gets set after C<perl Build.PL>

=item C<distdir ()>

Full path to the directory in which the C<prepare> call took place,
set after a call to C<prepare>. 

=item C<created ()>

BOOL indicating if the C<create> call exited successfully. This gets
set after C<Build> and C<Build test>.

=item C<installed ()>

BOOL indicating if the module was installed. This gets set after
C<Build install> exits successfully.

=item uninstalled ()

BOOL indicating if the module was uninstalled properly.

=item C<_create_args ()>

Storage of the arguments passed to C<create> for this object. Used
for recursive calls when satisfying prerequisites.

=item C<_install_args ()>

Storage of the arguments passed to C<install> for this object. Used
for recursive calls when satisfying prerequisites.

=back

=cut

=head1 METHODS

=head2 $bool = CPANPLUS::Dist::Build->format_available();

Returns a boolean indicating whether or not you can use this package
to create and install modules in your environment.

=cut

### check if the format is available ###
sub format_available {
    my $mod = 'Module::Build';
    unless( can_load( modules => { $mod => '0.2611' }, nocache => 1 ) ) {
        error( loc( "You do not have '%1' -- '%2' not available",
                    $mod, __PACKAGE__ ) );
        return;
    }

    return 1;
}


=head2 $bool = $dist->init();

Sets up the C<CPANPLUS::Dist::Build> object for use.
Effectively creates all the needed status accessors.

Called automatically whenever you create a new C<CPANPLUS::Dist> object.

=cut

sub init {
    my $dist    = shift;
    my $status  = $dist->status;

    $status->mk_accessors(qw[build_pl build test created installed uninstalled
                             _create_args _install_args _prepare_args
                             _mb_object _buildflags
                            ]);

    ### just in case 'format_available' didn't get called
    require Module::Build;

    return 1;
}

=pod

=head2 $bool = $dist->prepare([perl => '/path/to/perl', buildflags => 'EXTRA=FLAGS', force => BOOL, verbose => BOOL])

C<prepare> prepares a distribution, running C<Build.PL> 
and establishing any prerequisites this
distribution has.

The variable C<PERL5_CPANPLUS_IS_EXECUTING> will be set to the full path 
of the C<Build.PL> that is being executed. This enables any code inside
the C<Build.PL> to know that it is being installed via CPANPLUS.

After a successful C<prepare> you may call C<create> to create the
distribution, followed by C<install> to actually install it.

Returns true on success and false on failure.

=head2 $dist->create([perl => '/path/to/perl', buildflags => 'EXTRA=FLAGS', prereq_target => TARGET, force => BOOL, verbose => BOOL, skiptest => BOOL])

C<create> preps a distribution for installation. This means it will
run C<Build> and C<Build test>.
This will also satisfy any prerequisites the module may have.

If you set C<skiptest> to true, it will skip the C<Build test> stage.
If you set C<force> to true, it will go over all the stages of the
C<Build> process again, ignoring any previously cached results. It
will also ignore a bad return value from C<Build test> and still allow
the operation to return true.

Returns true on success and false on failure.

You may then call C<< $dist->install >> on the object to actually
install it.
