CPANPLUS::Module
- ### 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;
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 fake
objects,
there's the CPANPLUS::Module::Fake
class. To obtain a module object
consult the CPANPLUS::Backend
documentation.
Returns a list of all accessor methods to the object
An objects of this class has the following accessors:
Name of the module.
Name of the module.
Version of the module. Defaults to '0.0' if none was provided.
Extended path on the mirror.
Any comment about the module -- largely unused.
The name of the package.
Description of the module -- only registered modules have this.
The five character dslip string, that represents meta-data of the module -- again, only registered modules have this.
The CPANPLUS::Module::Status
object associated with this object.
(see below).
The CPANPLUS::Module::Author
object associated with this object.
The CPANPLUS::Internals
object that spawned this module object.
CPANPLUS
caches a lot of results from method calls and saves data
it collected along the road for later reuse.
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:
The installer type used for this distribution. Will be one of
'makemaker' or 'build'. This determines whether CPANPLUS::Dist::MM
or CPANPLUS::Dist::Build
will be used to build this distribution.
The dist object used to do the CPAN-side of the installation. Either
a CPANPLUS::Dist::MM
or CPANPLUS::Dist::Build
object.
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 ports
format, this may be a
CPANPLUS::Dist::Ports
object.
Undefined if you didn't specify a separate format to install through.
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.
Like prereqs, but these are necessary to be installed before the build process can even begin.
Flag indicating, if a signature check was done, whether it was OK or not.
The directory this distribution was extracted to.
The location this distribution was fetched to.
The text of this distributions README file.
Flag indicating if an uninstall call was done successfully.
Flag indicating if the create
call to your dist object was done
successfully.
Flag indicating if the install
call to your dist object was done
successfully.
The location of this distributions CHECKSUMS file.
Flag indicating if the checksums check was done successfully.
The checksum value this distribution is expected to have
This method returns a CPANPLUS::Module
object. Normal users
should never call this method directly, but instead use the
CPANPLUS::Backend
to obtain module objects.
This example illustrates a 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 new
.
Returns a module object on success and false on failure.
Returns the name of the package a module is in. For Acme::Bleach
that might be Acme-Bleach
.
Returns the version of the package a module is in. For a module
in the package Acme-Bleach-1.1.tar.gz
this would be 1.1
.
Returns the suffix added by the compression method of a package a
certain module is in. For a module in Acme-Bleach-1.1.tar.gz
, this
would be tar.gz
.
Returns a boolean indicating of the package a particular module is in, is actually a core perl distribution.
Returns a boolean indicating whether ANY VERSION
of this module
was supplied with the current running perl's core package.
Returns a boolean indicating if the module you are looking at, is
actually a bundle. Bundles are identified as modules whose name starts
with Bundle::
.
Returns a boolean indicating if the module you are looking at, is
actually an autobundle as generated by $cb->autobundle
.
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 Module::ThirdParty for more details.
Returns a reference to a hash with more information about a third-party
module. See the documentation about module_information()
in
Module::ThirdParty for more details.
Clones the current module object for tinkering with.
It will have a clean CPANPLUS::Module::Status
object, as well as
a fake CPANPLUS::Module::Author
object.
Fetches the module from a CPAN mirror. Look at CPANPLUS::Internals::Fetch::_fetch() for details on the options you can pass.
Extracts the fetched module. Look at CPANPLUS::Internals::Extract::_extract() for details on the options you can pass.
Gets the installer type for this module. This may either be build
or
makemaker
. If Module::Build
is unavailable or no installer type
is available, it will fall back to makemaker
. If both are available,
it will pick the one indicated by your config, or by the
prefer_makefile
option you can pass to this function.
Returns the installer type on success, and false on error.
Create a distribution object, ready to be installed. Distribution type defaults to your config settings
The optional args
hashref is passed on to the specific distribution
types' create
method after being dereferenced.
Returns a distribution object on success, false on failure.
See CPANPLUS::Dist
for details.
Convenience method around install()
that prepares a module
without actually building it. This is equivalent to invoking install
with target
set to prepare
Returns true on success, false on failure.
Convenience method around install()
that creates a module.
This is equivalent to invoking install
with target
set to
create
Returns true on success, false on failure.
Convenience wrapper around install()
that tests a module, without
installing it.
It's the equivalent to invoking install()
with target
set to
create
and skiptest
set to 0
.
Returns true on success, false on failure.
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 will be passed on to the relevant methods as they are called.
See CPANPLUS::Internals::Fetch
, CPANPLUS::Internals::Extract
and
CPANPLUS::Dist
for details.
Returns true on success, false on failure.
Returns a list of module objects the Bundle specifies.
This requires you to have extracted the bundle already, using the
extract()
method.
Returns false on error.
Fetches the readme belonging to this module and stores it under
$obj->status->readme
. Returns the readme as a string on
success and returns false on failure.
Returns the currently installed version of this module, if any.
Returns the location of the currently installed file of this module, if any.
Returns the directory (or more accurately, the @INC
handle) from
which this module was loaded, if any.
Returns a boolean indicating if this module is uptodate or not.
Returns a hashref with key/value pairs offering more information about
a particular module. For example, for Time::HiRes
it might look like
this:
- Author Jarkko Hietaniemi (jhi@iki.fi)
- Description High resolution time, sleep, and alarm
- Development Stage Released
- Installed File /usr/local/perl/lib/Time/Hires.pm
- Interface Style plain Functions, no references used
- Language Used C and perl, a C compiler will be needed
- Package Time-HiRes-1.65.tar.gz
- Public License Unknown
- Support Level Developer
- Version Installed 1.52
- Version on CPAN 1.65
Returns a list of module objects that represent the modules also present in the package of this module.
For example, for Archive::Tar
this might return:
- Archive::Tar
- Archive::Tar::Constant
- Archive::Tar::File
This function queries the CPAN testers database at http://testers.cpan.org/ for test results of specified module objects, module names or distributions.
Look at CPANPLUS::Internals::Report::_query_report() for details on the options you can pass and the return value to expect.
This function uninstalls the specified module object.
You can install 2 types of files, either man
pages or prog
ram
files. Alternately you can specify 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 .packlist
,
so if you used a module installer like say, ports
or apt
, you
should not use this, but use your package manager instead.
Returns a list of module objects representing all releases for this module on success, false on failure.
Returns a list of files used by this module, if it is installed.
Returns a list of directories used by this module.
Returns the ExtUtils::Packlist
object for this module.
Returns a list of files that are missing for this modules, but are present in the .packlist file.
Adds the current modules path to @INC
and $PERL5LIB
. This allows
you to add the module from its build dir to your path.
You can reset @INC
and $PERL5LIB
to its original state when you
started the program, by calling:
- $self->parent->flush('lib');
OBSOLETE
If a newer version of Module::Build is found in your path, it will
return this special
path. If the newest version of Module::Build
is found in your regular @INC
, the method will return false. This
indicates you do not need to add a special directory to your @INC
.
Note that this is only relevant if you're building your own
CPANPLUS::Dist::*
plugin -- the built-in dist types already have
this taken care of.
