27=head1 SYNOPSIS
28
4443dd53 29 $mm = CPANPLUS::Dist::MM->new( module => $modobj );

35=head1 DESCRIPTION
36
37C<CPANPLUS::Dist::MM> is a distribution class for MakeMaker related
38modules.
39Using this package, you can create, install and uninstall perl
40modules. It inherits from C<CPANPLUS::Dist>.
41
42=head1 ACCESSORS
43
44=over 4
45
46=item parent()
47
48Returns the C<CPANPLUS::Module> object that parented this object.
49
50=item status()
51
52Returns the C<Object::Accessor> object that keeps the status for
53this module.
54
55=back
56
57=head1 STATUS ACCESSORS
58
59All accessors can be accessed as follows:
60 $mm->status->ACCESSOR
61
62=over 4
63
64=item makefile ()
65
66Location of the Makefile (or Build file).
67Set to 0 explicitly if something went wrong.
68
69=item make ()
70
71BOOL indicating if the C<make> (or C<Build>) command was successful.
72
73=item test ()
74
75BOOL indicating if the C<make test> (or C<Build test>) command was
76successful.
77
78=item prepared ()
79
80BOOL indicating if the C<prepare> call exited succesfully
81This gets set after C<perl Makefile.PL>
82
83=item distdir ()
84
85Full path to the directory in which the C<prepare> call took place,
86set after a call to C<prepare>.
87
88=item created ()
89
90BOOL indicating if the C<create> call exited succesfully. This gets
91set after C<make> and C<make test>.
92
93=item installed ()
94
95BOOL indicating if the module was installed. This gets set after
96C<make install> (or C<Build install>) exits successfully.
97
98=item uninstalled ()
99
100BOOL indicating if the module was uninstalled properly.
101
102=item _create_args ()
103
104Storage of the arguments passed to C<create> for this object. Used
105for recursive calls when satisfying prerequisites.
106
107=item _install_args ()
108
109Storage of the arguments passed to C<install> for this object. Used
110for recursive calls when satisfying prerequisites.

115
116=head1 METHODS
117
118=head2 $bool = $dist->format_available();
119
120Returns a boolean indicating whether or not you can use this package
121to create and install modules in your environment.

155
156=pod $bool = $dist->init();
157
158Sets up the C<CPANPLUS::Dist::MM> object for use.
159Effectively creates all the needed status accessors.
160
161Called automatically whenever you create a new C<CPANPLUS::Dist> object.

175
176=pod $bool = $dist->prepare([perl => '/path/to/perl', makemakerflags => 'EXTRA=FLAGS', force => BOOL, verbose => BOOL])
177
178C<prepare> preps a distribution for installation. This means it will
179run C<perl Makefile.PL> and determine what prerequisites this distribution
180declared.
181
182If you set C<force> to true, it will go over all the stages of the
183C<prepare> process again, ignoring any previously cached results.
184
185When running C<perl Makefile.PL>, the environment variable
186C<PERL5_CPANPLUS_IS_EXECUTING> will be set to the full path of the
187C<Makefile.PL> that is being executed. This enables any code inside
188the C<Makefile.PL> to know that it is being installed via CPANPLUS.
189
190Returns true on success and false on failure.
191
192You may then call C<< $dist->create >> on the object to create the
193installable files.
