This is a plugin designed to help other plugins make configuration available to Javascript through HTML5 data attributes.
Copy config_tag.rb into your Jekyll plugins directory.
Given the following yaml configuration:
site_author:
name: Bob Loblaw
profession: Lawyer
sandwich: [avacado, bacon, lettuce, tomato]
url: http://j.mp/Ze0u3D
The following config tags:
{% config_tag site_author %}
{% config_tag sandwich tag:span %}
{% config_tag url classname:rick-roll %}
Will produce:
<div class='site-author' data-name='Bob Loblaw' data-profession='Lawyer'></div>
<span class='sandwich' data-value='avacado,bacon,lettuce,tomato'></span>
<div class='rick-roll' data-value='http://j.mp/Ze0u3D'></div>This is best when used with nested configurations like the first example. When a value contains an array, it will be joined with a comma; if it is a hash, it will be converted to JSON which can be parsed in Javascript with JSON.parse(json).
Most of the work happens in the config_tag method, which can be used directly by other Jekyll plugins if they want to wrap this within some other feature.
