Another quick update to blogmore.el, again to fix an issue I've run into with the new frontmatter-handling code. This time it's to address an actual crash that could happen if a property was available but empty. For example, if a post had frontmatter that looked like this:
title: "blogmore.el v5.2.0"
date: "2026-06-12 08:31:15+0100"
category: Emacs
tags:
And I then went to use blogmore-add-tag, I'd get a crash saying:
Wrong type argument: sequencep, :null
The reason being that tags was being parsed with a value of :null, rather than (as before) having a value of nil (which of course meant I had a nice empty list to do things with). It was an easy enough fix.
At this point I think I've managed to shake out any serious issues with the proper YAML-parsing approach to frontmatter, as I've used it to write a handful of posts now.
