=head1 NAME

CPANPLUS::Dist::MM - distribution class for MakeMaker related modules

=head1 SYNOPSIS

$mm = CPANPLUS::Dist::MM->new( module => $modobj );

$mm->create; # runs make && make test
$mm->install; # runs make install


=head1 DESCRIPTION

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

=head1 ACCESSORS

=over 4

=item parent()

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

=item 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:
$mm->status->ACCESSOR

=over 4

=item makefile ()

Location of the Makefile (or Build file).
Set to 0 explicitly if something went wrong.

=item make ()

BOOL indicating if the C<make> (or C<Build>) command was successful.

=item test ()

BOOL indicating if the C<make test> (or C<Build test>) command was
successful.

=item prepared ()

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

=item distdir ()

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

=item created ()

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

=item installed ()

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

=item uninstalled ()

BOOL indicating if the module was uninstalled properly.

=item _create_args ()

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

=item _install_args ()

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

=head1 METHODS

=head2 $bool = $dist->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 $dist = shift;

### we might be called as $class->format_available =/

}

return 1;
}

=pod

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

Sets up the C<CPANPLUS::Dist::MM> 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[makefile make test created installed uninstalled
bin_make _prepare_args _create_args _install_args]
);

return 1;
}

=pod

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

C<prepare> preps a distribution for installation. This means it will
run C<perl Makefile.PL> and determine what prerequisites this distribution
declared.

If you set C<force> to true, it will go over all the stages of the
C<prepare> process again, ignoring any previously cached results.

When running C<perl Makefile.PL>, the environment variable
C<PERL5_CPANPLUS_IS_EXECUTING> will be set to the full path of the
C<Makefile.PL> that is being executed. This enables any code inside
the C<Makefile.PL> to know that it is being installed via CPANPLUS.

Returns true on success and false on failure.

You may then call C<< $dist->create >> on the object to create the
installable files.

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

C<create> creates the files necessary for installation. This means
it will run C<make> and C<make test>. This will also scan for and
attempt to satisfy any prerequisites the module may have.

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