NAME

       CPANPLUS::Selfupdate - self-updating for CPANPLUS

SYNOPSIS

           $su     = $cb->selfupdate_object;

           @feats  = $su->list_features;
           @feats  = $su->list_enabled_features;

           @mods   = map { $su->modules_for_feature( $_ ) } @feats;
           @mods   = $su->list_core_dependencies;
           @mods   = $su->list_core_modules;

           for ( @mods ) {
               print $_->name " should be version " . $_->version_required;
               print "Installed version is not uptodate!"
                   unless $_->is_installed_version_sufficient;
           }

           $ok     = $su->selfupdate( update => 'all', latest => 0 );

METHODS

   $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

       "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.
