NAME
   WWW::Comic - Retrieve comic strip images

SYNOPSIS
    use strict;
    use WWW::Comic qw();

# Create a WWW::Comic object
    my $wc = new WWW::Comic;

# Get a list of supported comics
    my @comics = $wc->comics;

# Allow HTTP requests to retrieve a full list of supported
    # comics if necessary (some plugins may not know what comics
    # they support until they make an HTTP request)
    my @comics = $wc->comics(probe => 1);

for my $comic (@comics) {
        # Get the most recent comic strip URL for $comic
        my $url = $comic->strip_url(comic => $comic);

    # Download the most recent comic strip
        # for $comic in to $blob
        my $blob = $comic->get_strip(comic => $comic);

    # Write the most recent comic strip for
        # $comic to disk
        my $filename = $comic->mirror_strip(comic => $comic);
    }

DESCRIPTION
   This module will download cartoon comic strip images from various
   websites and return a binary blob of the image, or write it to disk.
   Multiple comic strips can be supported through subclassed plugin
   modules.

   A number of plugin modules are bundled as part of this distrubution. You
   may want to refer to their documentation for any additional custom
   methods and features. Specifically, WWW::Comic::Plugin::UFS and
   WWW::Comic::Plugin::uComics require use of the "probe" paramater with
   the "comics" method on order to retrieve a list of supported commics.

   To find out what plugin modules you currently have installed and
   available, run the following:

    perl -MWWW::Comic -MData::Dumper -e"print Dumper([WWW::Comic->new->plugins]);"

METHODS
 new
    my $wc = new WWW::Comic;

   Creates a new WWW::Comic object.

 comics
    my @comics = $wc->comics(probe => 1);

   Returns a list of available comics. The "probe" paramater is optional.
   (See below).

   probe
       This paramater is an optional boolean value supported by a few
       plugins that do not automatically know what comics they support.
       Specifying a boolean true value for this paramater will tell those
       plugins that they should make HTTP requests to find out what comics
       they can make available. Plugins should cache this information in
       memory once they have performed an initial probe.

 strip_url
    # Get the URL of the most recent "mycomic" comic image
    my $url = $wc->strip_url(comic => "mycomic");

# Get the URl of a specific "mycomic" comic image
    my $specificStripUrl = $wc->strip_url(
                                comic => "mycomic",
                                id => 990317
                            );

   Returns the URL of a comic strip. The "comic" paramater is mandatory and
   must be a valid supported comic as listed by the "comics()" method. The
   most recent comic strip image URL will be returned unless otherwise
   specified (see the "id" paramater below).

   This method will return an "undef" value upon failure.

   The "id" paramater is optional and can be used to specify a specific
   comic (if supported by the plugin in question). Comic IDs are typically
   date based in some way, but this is unique to each comic and follows no
   special format for the purposes of this module. See each plugin module's
   documentation for further information.

   comic
       This paramater is mandatory. It specifies the comic that this method
       should process. See the "comics()" method.

   id  This paramater is optional. It specifies a specfic comic that should
       be processed.

 get_strip
    # Retrieve the most recent "mycomic" comic strip image
    my $imageBlob = $wc->get_strip(comic => "mycomic");

# Retrieve a specific "mycomic" comic strip image
    my $image2 = $wc->get_strip(
                           comic => "mycomic",
                           id => "0042304973"
                       );

   Downloads a copy of a comic strip image and returns the binary data as a
   scalar. The "comic" paramater is mandatory and must be a valid supported
   comic as listed by the "comics()" method. The most recent comic strip
   image will be returned unless otherwise specified.

   This method will return an "undef" value upon failure.

   comic
       This paramater is mandatory. It specifies the comic that this method
       should process. See the "comics()" method.

   id  This paramater is optional. It specifies a specfic comic that should
       be processed.

   url This paramater is optional. It specifies a specific comic that
       should be processed. If specified it must be a fully qualified and
       valid absolute HTTP URL. This paramater is typically only used when
       being called indirectly by the "mirror_strip()" method.

 mirror_strip
    # Write the most recent "mycomic" comic strip to disk
    # and return the name of the file that was written
    my $filename = $wc->mirror_strip(comic => "mycomic");

# Write the "mycomic" comic strip image (reference 132)
    # to disk, specifcally to mycomic.gif, and return the
    # actual filename that was written to disk in to $file2
    my $file2 = $wc->mirror_strip(
                          comic => "mycomic",
                          id => "132",
                          filename => "mycomic.gif"
                     );

   Download a copy of a comic strip image and write it to disk, returning
   the name of the file that was actually written. This method accepts the
   same paramaters as the "get_strip()" method, with the addition of the
   "filename" paramater.

   This method will return an "undef" value upon failure.

   comic
       This paramater is mandatory. It specifies the comic that this method
       should process. See the "comics()" method.

   id  This paramater is optional. It specifies a specfic comic that should
       be processed.

   url This paramater is optional. It specifies a specific comic that
       should be processed. If specified it must be a fully qualified and
       valid absolute HTTP URL.

   filename
       This paramater is optional. It specifiec the target filename that
       you would like to be written to disk. If you do not supply an image
       file extension, one will be added for you automatically. If you
       specify an image file extension that differs to the file format of
       the file that is to ultimately be written disk, it will be altered
       for you automatically.

 plugins
    my @plugins = $wc->plugins;

   Return a list of loaded plugins.

PLUGINS
   Support for different comics is handled through the WWW::Comic::Plugin
   superclass. See the POD for WWW::Comic::Plugin on how to create a new
   plugin.
