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.
