# NAME

CPANPLUS::Selfupdate

# 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.
