NAME    BackPAN::Index - An interface to the BackPAN indexSYNOPSIS        use BackPAN::Index;        my $backpan = BackPAN::Index->new;        # These are all DBIx::Class::ResultSet's        my $files    = $backpan->files;        my $dists    = $backpan->dists;        my $releases = $backpan->releases("Acme-Pony");        # Use DBIx::Class::ResultSet methods on them        my $release = $releases->single({ version => '1.23' });        my $dist = $backpan->dist("Test-Simple");        my $releases = $dist->releases;DESCRIPTION    This downloads, caches and parses the BackPAN index into a local    database for efficient querying.    Its a pretty thin wrapper around DBIx::Class returning    DBIx::Class::ResultSet objects which makes it efficient and flexible.    The Comprehensive Perl Archive Network (CPAN) is a very useful    collection of Perl code. However, in order to keep CPAN relatively    small, authors of modules can delete older versions of modules to only    let CPAN have the latest version of a module. BackPAN is where these    deleted modules are backed up. It's more like a full CPAN mirror, only    without the deletions. This module provides an index of BackPAN and some    handy methods.METHODS  new        my $backpan = BackPAN::Index->new(\%options);    Create a new object representing the BackPAN index.    It will, if necessary, download the BackPAN index and compile it into a    database for efficient storage. Initial creation is slow, but it will be    cached.    new() takes some options   update    Because it is rather large, BackPAN::Index caches a copy of the BackPAN    index and builds a local database to speed access. This flag controls if    the local index is updated.    If true, forces an update of the BACKPAN index.    If false, the index will never be updated even if the cache is expired.    It will always create a new index if one does not exist.    By default the index is cached and checked for updates according to    "<$backpan-"cache_ttl>>.   cache_ttl    How many seconds before checking for an updated index.    Defaults to an hour.   debug    If true, debug messages will be printed.    Defaults to false.   releases_only_from_authors    If true, only files in the "authors" directory will be considered as    releases. If false any file in the index may be considered for a    release.    Defaults to true.   cache_dir    Location of the cache directory.    Defaults to whatever App::Cache does.   backpan_index_url    URL to the BackPAN index.    Defaults to a sensible location.  files        my $files = $backpan->files;    Returns a ResultSet representing all the files on BackPAN.  files_by        my $files = $backpan->files_by($cpanid);        my @files = $backpan->files_by($cpanid);    Returns all the files by a given $cpanid.    Returns either a list of BackPAN::Index::Files or a ResultSet.  dists        my $dists = $backpan->dists;    Returns a ResultSet representing all the distributions on BackPAN.  dist        my $dists = $backpan->dist($dist_name);    Returns a single BackPAN::Index::Dist object for $dist_name.  dists_by        my $dists = $backpan->dists_by($cpanid);        my @dists = $backpan->dists_by($cpanid);    Returns the dists which contain at least one release by the given    $cpanid.    Returns either a ResultSet or a list of the Dists.  dists_changed_since        my $dists = $backpan->dists_changed_since($time);    Returns a ResultSet of distributions which have had releases at or after    after $time.  releases        my $all_releases  = $backpan->releases();        my $dist_releases = $backpan->releases($dist_name);    Returns a ResultSet representing all the releases on BackPAN. If a    $dist_name is given it returns the releases of just one distribution.  release        my $release = $backpan->release($dist_name, $version);    Returns a single BackPAN::Index::Release object for the given $dist_name    and $version.  releases_by        my $releases = $backpan->releases_by($cpanid);        my @releases = $backpan->releases_by($cpanid);    Returns all the releases of a single author.    Returns either a list of Releases or a ResultSet representing those    releases.  releases_since        my $releases = $backpan->releases_since($time);    Returns a ResultSet of releases which were released at or after $time.EXAMPLES    The real power of BackPAN::Index comes from DBIx::Class::ResultSet. Its    very flexible and very powerful but not always obvious how to get it to    do things. Here's some examples.        # How many files are on BackPAN?        my $count = $backpan->files->count;        # How big is BackPAN?        my $size = $backpan->files->get_column("size")->sum;        # What are the names of all the distributions?        my @names = $backpan->dists->get_column("name")->all;        # What path contains this release?        my $path = $backpan->release("Acme-Pony", 1.01)->path;        # Get all the releases of Moose ordered by version        my @releases = $backpan->dist("Moose")->releases                                              ->search(undef, { order_by => "version" });AUTHOR    Michael G Schwern <schwern@pobox.com>COPYRIGHT    Copyright 2009, Michael G SchwernLICENSE    This module is free software; you can redistribute it or modify it under    the same terms as Perl itself.SEE ALSO    DBIx::Class::ResultSet, BackPAN::Index::File, BackPAN::Index::Release,    BackPAN::Index::Dist    Repository: <http://github.com/acme/parse-backpan-packages> Bugs:    <http://rt.cpan.org/Public/Dist/Display.html?Name=Parse-BACKPAN-Packages    >
