SYNOPSIS

... load ALPM with options first ...

my $localdb = ALPM->localdb;
my $name    = $localdb->name;
my $perl    = $localdb->find('perl');

my $url       = 'ftp://ftp.archlinux.org/community/os/i686';
my $syncdb    = ALPM->register_db( 'community' => $url );

for my $pkg ( $syncdb->search( 'perl' ) ) {
    printf "%s %s\n", $pkg->name, $pkg->version;
}

for my $pkg ( $syncdb->find_group('xfce4')->packages ) {
    print join( q{ }, $pkg->attribs('name', 'version') ), "\n";
}

my @cache = $syncdb->pkgs;

METHODS

name

Usage   : my $name = $db->name;
Returns : The name of the repository database.
          Ex: core, extra, community, etc...

url

Usage   : my $url = $db->url;
Returns : The url of the repository, the same one the DB
          was initialized with or the empty string if this
          is a 'local' database.

find

Usage   : my $package = $db->find( $package_name )
Params  : $package_name - Exact name of the package to retrieve.
Returns : An ALPM::Package object if the package is found.
          undef if the package with that name is not found.

find_group

Usage   : my $group = $db->find_group( $group_name );
Returns : An ALPM::Group object if it is found or undef.
          ALPM::Group objects have two accessors:
          $group->name - the name of the group
          $group->pkgs - A list of package objects in the group
Usage   : my @results = $db->search( 'foo', 'bar', 'baz' );
Params  : A list of strings to search for.
Returns : An array of package objects whose name matched the search.

packages

Usage   : my @pkgs = $db->packages;
Params  : None
Returns : An array of all packages in the DB.
Notes   : This is a wrapper for the C<get_pkg_cache> method.
          It is easier if you want a list.

groups

Usage   : my @groups = $db->groups;
Returns : An array of all groups in the DB.

pkgs

This is an alias for the packages method.

Usage   : my @pkgs = $db->pkgs;

get_pkg_cache

Usage    : my $cache_ref = $db->get_pkg_cache;
Comments : Resembles the alpm_db_get_pkgcache function.
Returns  : An arrayref of package objects in the DB cache.

pkgs_ref

This is an alias for the get_pkg_cache method.

Usage   : my $pkgs_ref = $db->pkgs_ref;

update

Usage   : $db->update;
Purpose : Updates the local copy of the database's package list.
Comment : This needs to create a transaction to work, so make sure
          you don't have any active transactions.

          Things may work incorrectly if the database is not updated.
          If there is no local db copy, the package cache will be empty.
Returns : 1
TODO    : Provide different return values like alpm does.
