$ok = $su−>selfupdate( update => 'all', latest
=> 0 );
$self =
CPANPLUS::Selfupdate−>new( $backend_object );
Sets up a new selfupdate object. Called automatically when a
new backend object is created.
@cat =
$self−>list_categories
Returns a list of categories that the "selfupdate"
method accepts.
See "selfupdate" for details.
%list =
$self−>list_modules_to_update( update =>
"core|dependencies|enabled_features|features|all",
[latest => BOOL ] )
List which modules "selfupdate" would upgrade. You
can update either the core ( CPANPLUS
itself), the core dependencies, all features you have
currently turned on, or all features available, or
everything.
The "latest" option determines whether it should update to the latest version on CPAN, or if the minimal required version for CPANPLUS is good enough.
Returns a hash of feature names and lists of module objects to be upgraded based on the category you provided. For example:
%list = $self−>list_modules_to_update( update => 'core' );
Would return:
( core => [ $module_object_for_cpanplus ] );
$bool =
$self−>selfupdate( update =>
"core|dependencies|enabled_features|features|all",
[latest => BOOL, force =>
BOOL ] )
Selfupdate CPANPLUS. You can update either
the core ( CPANPLUS itself), the core
dependencies, all features you have currently turned on, or
all features available, or everything.
The "latest" option determines whether it should update to the latest version on CPAN, or if the minimal required version for CPANPLUS is good enough.
Returns true on success, false on error.
@features =
$self−>list_features
Returns a list of features that are supported by
CPANPLUS.
@features =
$self−>list_enabled_features
Returns a list of features that are enabled in your current
CPANPLUS installation.
@mods =
$self−>modules_for_feature( FEATURE
[,AS_HASH] )
Returns a list of "CPANPLUS::Selfupdate::Module"
objects which represent the modules required to support this
feature.
For a list of features, call the "list_features" method.
If the "AS_HASH" argument is provided, no module objects are returned, but a hashref where the keys are names of the modules, and values are their minimum versions.
@mods =
$self−>list_core_dependencies( [
AS_HASH ] )
Returns a list of "CPANPLUS::Selfupdate::Module"
objects which represent the modules that comprise the core
dependencies of CPANPLUS.
If the "AS_HASH" argument is provided, no module objects are returned, but a hashref where the keys are names of the modules, and values are their minimum versions.
@mods =
$self−>list_core_modules( [ AS_HASH
] )
Returns a list of "CPANPLUS::Selfupdate::Module"
objects which represent the modules that comprise the core
of CPANPLUS.
If the "AS_HASH" argument is provided, no module objects are returned, but a hashref where the keys are names of the modules, and values are their minimum versions.
"CPANPLUS::Selfupdate::Module" extends "CPANPLUS::Module" objects by providing accessors to aid in selfupdating CPANPLUS.
These objects are returned by all methods of "CPANPLUS::Selfupdate" that return module objects.
$version =
$mod−>version_required
Returns the version of this module required for
CPANPLUS.
$bool =
$mod−>is_installed_version_sufficient
Returns true if the installed version of this module is
sufficient for CPANPLUS, or false if it is
not.
