Breadcrumbs helper for Middleman
Install the gem as usual: put gem 'middleman-breadcrumbs' in Gemfile, then run bundle install.
Put activate :breadcrumbs in config.rb (not in the configure :build block).
In your view files, just call breadcrumbs(current_page) to display breadcrumbs.
The breadcrumb levels are separated with > by default. If you want a different separator, use the :separator option—e.g., breadcrumbs(current_page, separator: '|||').
If you want to wrap each breadcrumb level in a tag, pass the tag name to the :wrapper option. For example, if you want your breadcrumbs in a list:
<ul>
<%= breadcrumbs current_page, wrapper: :li, separator: nil %>
</ul>This will wrap each breadcrumb level in a <li> element.
