Minimal_mistakes, excerpt, and `relative_url`

Hi,

With minimal_mistakes’s layout: splash I’m trying to use

intro:
  - title: Welcome!
    excerpt: "An [open-source](/about/license) something."

That’s not good - I need the url to be relative. But

intro:
  - title: Welcome!
    excerpt: "An [open-source]({{'/about/license' | relative_url}}) something."

triggers markdownify to emit a table thanks to the |. What’s the magic spell that allows me to pipe into relative_url in a markdown link? Help appreciated!

Cheers, Axel.

Liquid isn’t allowed in YAML front matter. So filters like relative_url aren’t going to work.

Search through the old posts as this has come up by others. I forget if there is a plug-in that enables it or not.
