NAME
CPANPLUS::Module - CPAN module objects for CPANPLUS
SYNOPSIS
### 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;
DESCRIPTION
"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.
CLASS METHODS
accessors ()
Returns a list of all accessor methods to the object
ACCESSORS
An objects of this class has the following accessors:
name
Name of the module.
module
Name of the module.
version
Version of the module. Defaults to '0.0' if none was provided.
path
Extended path on the mirror.
comment
Any comment about the module -- largely unused.
package
The name of the package.
description
Description of the module -- only registered modules have this.
dslip
The five character dslip string, that represents meta-data of the module -- again,
only registered modules have this.
status
The "CPANPLUS::Module::Status" object associated with this object. (see below).
author
The "CPANPLUS::Module::Author" object associated with this object.
parent
The "CPANPLUS::Internals" object that spawned this module object.
STATUS ACCESSORS
"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:
installer_type
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.
dist_cpan
The dist object used to do the CPAN-side of the installation. Either a
"CPANPLUS::Dist::MM" or "CPANPLUS::Dist::Build" object.
dist
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.
prereqs | requires
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.
configure_requires
Like prereqs, but these are necessary to be installed before the build process can
even begin.
signature
Flag indicating, if a signature check was done, whether it was OK or not.
extract
The directory this distribution was extracted to.
fetch
The location this distribution was fetched to.
readme
The text of this distributions README file.
uninstall
Flag indicating if an uninstall call was done successfully.
created
Flag indicating if the "create" call to your dist object was done successfully.
installed
Flag indicating if the "install" call to your dist object was done successfully.
checksums
The location of this distributions CHECKSUMS file.
checksum_ok
Flag indicating if the checksums check was done successfully.
checksum_value
The checksum value this distribution is expected to have
METHODS
$self = CPANPLUS::Module->new( OPTIONS )
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.
$mod->package_name( [$package_string] )
Returns the name of the package a module is in. For "Acme::Bleach" that might be
"Acme-Bleach".
$mod->package_version( [$package_string] )
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.
$mod->package_extension( [$package_string] )
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".
$mod->package_is_perl_core
Returns a boolean indicating of the package a particular module is in, is actually a core
perl distribution.
$mod->module_is_supplied_with_perl_core( [version => $]] )
Returns a boolean indicating whether "ANY VERSION" of this module was supplied with the
current running perl's core package.
$mod->is_bundle
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::".
$mod->is_autobundle;
Returns a boolean indicating if the module you are looking at, is actually an autobundle
as generated by "$cb->autobundle".
$mod->is_third_party
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.
$mod->third_party_information
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.
$clone = $self->clone
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.
$where = $self->fetch
Fetches the module from a CPAN mirror. Look at CPANPLUS::Internals::Fetch::_fetch() for
details on the options you can pass.
$path = $self->extract
Extracts the fetched module. Look at CPANPLUS::Internals::Extract::_extract() for details
on the options you can pass.
$type = $self->get_installer_type([prefer_makefile => BOOL])
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.
$dist = $self->dist([target => 'prepare|create', format => DISTRIBUTION_TYPE, args => {key =>
val}]);
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.
$bool = $mod->prepare( )
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.
$bool = $mod->create( )
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.
$bool = $mod->test( )
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.
$bool = $self->install([ target => 'init|prepare|create|install', format => FORMAT_TYPE,
extractdir => DIRECTORY, fetchdir => DIRECTORY, prefer_bin => BOOL, force => BOOL, verbose
=> BOOL, ..... ]);
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.
@list = $self->bundle_modules()
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.
$text = $self->readme
Fetches the readme belonging to this module and stores it under "$obj->status->readme".
Returns the readme as a string on success and returns false on failure.
$version = $self->installed_version()
Returns the currently installed version of this module, if any.
$where = $self->installed_file()
Returns the location of the currently installed file of this module, if any.
$dir = $self->installed_dir()
Returns the directory (or more accurately, the @INC handle) from which this module was
loaded, if any.
$bool = $self->is_uptodate([version => VERSION_NUMBER])
Returns a boolean indicating if this module is uptodate or not.
$href = $self->details()
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 AT 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
@list = $self->contains()
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
@list_of_hrefs = $self->fetch_report()
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.
$bool = $self->uninstall([type => [all|man|prog])
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.
@modobj = $self->distributions()
Returns a list of module objects representing all releases for this module on success,
false on failure.
@list = $self->files ()
Returns a list of files used by this module, if it is installed.
@list = $self->directory_tree ()
Returns a list of directories used by this module.
@list = $self->packlist ()
Returns the "ExtUtils::Packlist" object for this module.
@list = $self->validate ()
Returns a list of files that are missing for this modules, but are present in the
.packlist file.
$bool = $self->add_to_includepath;
Adds the current modules path to @INC and $PERL5LIB. This allows you to add the module
from its build dir to your path.
It also adds the current modules "bin" and/or "script" paths to the PATH.
You can reset $PATH, @INC and $PERL5LIB to their original state when you started the
program, by calling:
$self->parent->flush('lib');
$path = $self->best_path_to_module_build();
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.
