Utopia::Gallery

This extension for Utopia provides tags for generating photo galleries. Works well in conjunction with jQuery.LiteBox.

Build Status Code Climate Coverage Status

Installation

Add this line to your website's Gemfile:

gem 'utopia-gallery'

And then execute:

$ bundle

VIPS

If you want to use utopia-gallery with PDFs or SVGs, you need to ensure you have VIPS compiled correctly.

$ vips pdfload
load PDF with libpoppler

On Arch linux:

$ sudo pacman -S poppler-glib cairo librsvg

Usage

Require the tag in your config/environment.rb:

require 'utopia/gallery'

In your config.ru add the gallery namespace:

use Utopia::Content, namespaces: {
	'gallery' => Utopia::Gallery::Tags.new
}

In your xnode:

<gallery:container path="_photos"/>

Customizing Generated Markup

The best way to customize the output is to specify a tag to use:

<gallery:container path="_photos" tag="content:photo"/>

Add _photo.xnode such as:

<figure class="photo">
	<a href="#{attributes[:src].large}" title="#{attributes[:alt]}">
		<img src="#{attributes[:src].small}" alt="#{attributes[:alt]}"/>
	</a>
	<?r if caption = attributes[:alt].caption ?>
		<figcaption>#{caption}</figcaption>
	<?r end ?>
</figure>

Or, if you prefer the <picture> element:

<figure class="photo">
	<a href="#{attributes[:src].large}" title="#{attributes[:alt]}">
		<picture>
			<source srcset="#{attributes[:src].small}, #{attributes[:src].medium} 2x"/>
			<img src="#{attributes[:src].small}" alt="#{attributes[:alt]}"/>
		</picture>
	</a>
	<?r if caption = attributes[:alt].caption ?>
		<figcaption>#{caption}</figcaption>
	<?r end ?>
</figure>

Adding Captions

You can add captions and other metadata by adding a gallery.yaml file:

bear.jpg:
  caption: "Brown bear is angry!"
  order: 1

This file needs to be placed in the same directory as the images, and metadata can be accessed via the alt attribute, e.g. attributes[:alt]['caption'].
