Strip http:// and https:// from URLs natively using Twig
Don't like those pesky protocols trashing your oh-so-beautiful design? So, so good using Twig's replace
filter:
<a href="{{ venue.venueUrl }}"> {{ venue.venueUrl | replace({'http://': '', 'https://': ''}) }} </a>
Quite why I was pissing about with the trim
filter I've no idea, though it isn't obvious from the docs.
