Name ^

WWW::PGXN::Extension - Extension metadata fetched from PGXN

Synopsis ^

  my $pgxn = WWW::PGXN->new( url => 'http://api.pgxn.org/' );
  my $ext  = $pgxn->get_extension('pgTAP');
  $ext->download_stable_to('.');

Description ^

This module represents PGXN extension metadata fetched from PGXN>. It is not intended to be constructed directly, but via the "get_extension" in WWW::PGXN method of WWW::PGXN.

Interface ^

Instance Accessors

name

  my $name = $extension->name;
  $extension->name($name);

The name of the extension.

latest

  my $latest = $extension->latest;
  $extension->latest($latest);

The status of the latest release. Should be one of:

stable
testing
unstable

Instance Methods

stable_info

testing_info

unstable_info

  my $stable_info   = $extension->stable_info;
  my $testing_info  = $extension->testing_info;
  my $unstable_info = $extension->unstable_info;

Returns a hash reference describing the latest version of the extension for the named release status. The supported keys are:

dist

The name of the distribution in which the extension may be found.

version

The version of the distribution in which the extension may be found.

abstract

A brief description of the extension. Available only from PGXN API servers, not mirrors.

sha1

The SHA1 hash for the distribution archive file.

docpath

A path to the documentation for the extension, if any.

If no release has been made with the given status, an empty hash reference will be returned. Here's an example of the structure for a distribution loaded from an API server:

  {
      dist     => 'pair',
      version  => '0.1.1',
      abstract => 'A key/value pair data type',
      sha1     => 'c552c961400253e852250c5d2f3def183c81adb3',
      docpath  => 'doc/pair',
  }

latest_info

  my $latest_info = $extension->latest_info;

Returns a hash reference describing the latest version of the extension. Essentially a convenience method for:

    my $meth = $extension->latest . '_info';
    my $info = $extension->$meth;

info_for_version

  my $version_info = $extension->info_for_version;

Returns a hash reference containing the distribution information for the named version of the extension, if it exists. The supported keys are:

dist

The name of the distribution in which the version of the extension may be found.

version

The version of the distribution in which the version of the extension may be found.

date

The release date the distribution containing the version of the extension. Available only from PGXN API servers, not mirrors.

Returns undef if no such version of the extension exists.

stable_distribution

testing_distribution

unstable_distribution

  my $stable_distribution   = $extension->stable_distribution;
  my $testing_distribution  = $extension->testing_distribution;
  my $unstable_distribution = $extension->unstable_distribution;

Returns a WWW::PGXN::Distribution object describing the distribution containing the distribution with the named release status. Returns undef if no distribution contains the extension with that status.

latest_distribution

Returns a WWW::PGXN::Distribution object describing the distribution in which the latest version of the extension is found. Essentially a convenience method for:

    my $meth = $extension->latest . '_distribution';
    my $dist = $extension->$meth;

distribution_for_version

  my $version_distribution = $extension->distribution_for_version($version);

Returns a WWW::PGXN::Distribution object describing the distribution in which the named version of the extension is found. Returns undef if no such version of the extension exists.

download_stable_to

download_testing_to

download_unstable_to

  my $stable_file   = $extension->download_stable_to('/usr/src');
  my $testing_file  = $extension->download_testing_to('.');
  my $unstable_file = $extension->download_unstable_to('mfile.zip');

Downloads the distribution containing the latest version of the extension with the named release status. Pass the name of the file to save to, or the name of a directory. If a directory is specified, the file will be written with the same name as it has on PGXN, such as pgtap-0.24.0.zip. Either way, the name of the file written will be returned. Regardless of the file's name, it will always be a zip archive.

download_latest_to

  my $file = $extension->download_latest_to($file);

Download the distribution containing the latest version of the distribution, regardless of its release status. Essentially a convenience method for:

    my $meth = 'download_' . $extension->latest . '_to';
    my $file = $extension->$meth('.');

download_version_to

  my $file = $extension->download_version_to($version, $file);

Download the distribution containing the specified version of the extension.
