I am trying to read the URL from within collection.liquid. The URL contains a tag filter.

Let me give you an example of such URL:

http://shop.myshopify.com/collections/playback-graphics/compilation

From within collection.liquid, I must determine if the last argument in the URL is ‘compilation’ as the markup will be very different on that page in that’s the case. ‘compilation’ is a tag, it is the tag used to filter the collection.

The following Output will output this: /collections/playback-graphics:

{{ collection.url }}

I am able to print all tags used by products within the collection, and using the filter highlight_active_tag the active tag will get printed with a special class-ed span next to it.

{% for tag in tags %} {{ tag | highlight_active_tag }} {% endfor %}

But how do I read the active tag? How do I get a handle to it?
