=head1 NAME

Mojolicious::Plugin::Cloudinary - Talk with cloudinary.com

=head1 DESCRIPTION

This register the methods from the L module as helpers in
your L web application. See L for details.

=head1 SYNOPSIS

  use Mojolicious::Lite;

  plugin cloudinary => {cloud_name => $str, api_key => $str, api_secret => $str};

  post "/upload" => sub {
    my $c = shift;

    $c->delay(
      sub {
        my ($delay) = @_;
        $c->cloudinary_upload({file => $c->param("upload_param")}, $delay->begin);
      },
      sub {
        my ($delay, $res, $tx) = @_;
        return $c->render(json => $res) if $res;
        return $c->render_exception;
      },
    );
  }

=head1 ATTRIBUTES

=head2 js_image

This string will be used as the image src for images constructed by
L. The default is "/image/blank.png".

=head1 HELPERS

=head2 cloudinary_upload

See L.

=head2 cloudinary_destroy

See L.

=head2 cloudinary_url_for

See L.

=head2 cloudinary_image

  $str = $c->cloudinary_image($public_id, $url_for_args, $image_args);

This will use L to create an image
tag where "src" is set to a cloudinary image. C<$url_for_args> are passed
on to L and C<$image_args> are passed on to
L.

=head2 cloudinary_js_image

  $str = $c->cloudinary_js_image($public_id, $url_for_args);

About the same as L, except it creates an image which can
handled by the cloudinary jQuery plugin which you can read more about here:
L

Example usage:

  $c->cloudinary_js_image(1234567890 =>
      {width => 115, height => 115, crop => "thumb", gravity => "faces", radius => "20"});

...will produce:


    class="cloudinary-js-image"
    alt="1234567890"
    data-src="1234567890"
    data-width="115"
    data-height="135"
    data-crop="thumb"
    data-gravity="faces"
    data-radius="20">

Note: The "class" and "alt" attributes are fixed for now.

=head1 METHODS

=head2 register

Will register the L in the L application.
