=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 succesfully
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 succesfully. 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' } ) ) {
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

my $dist = shift;
my $status = $dist->status;
$status->mk_accessors(qw[build_pl build test created installed uninstalled

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

=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 succcesfull 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.

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.
