RSS plugin not rendering relative links correctly

[brabster]

I've set up an RSS feed for my blog but it seems to be misbehaving, specifically rendering internal links to other pages and images as literally what I typed in my markdown, not what they end up as after build.

The links in the most recent post are wrong:

Image should be: https://tempered.works/2024-03-31-exploring-setup-py/assets/hero.webp
Link should be: https://tempered.works/posts/2024/03/23/irresponsible-expertise---python-packages/

Guessing I've not missed something as the same issue seems to be happening on mkdocs-material's own blog but maybe? Did I miss something or is this an issue?

Here's my settings:

Thanks for reporting. This isn't specifically related to Material for MkDocs, as it will also happen with other themes, so it's a good idea to report this upstream to the authors of the RSS plugin. My guess is that URLs should be resolved by the plugin to absolute URLs, so RSS feeders render them consistently.

I have been wondering about how the RSS plugin deals with rendering content as well recently. This is the place where the Markdown is rendered. for the RSS feed and it does not give any special treatment to links or anything else. I think that explains the observed behavior. The consequence is to work around this by ensuring that only standard Markdown and HTML links are used in the excerpt of a post.

My use case was that I have an admonition in the excerpt, which does what I want in the blog but in the RSS feed I get the raw Markdown because the admonition syntax is an extension. What I would have liked would have been to get the corresponding HTML divs instead. I do wonder what the rationale was to use the raw Markdown as the source instead of the finished HTML?

As @squidfunk say, best to report this upstream.

Hmm I really wanted this fixed so I had a go. Couldn't find a neat solution, so I ended up working directly with the html output but it works for my case.

I've only implemented just what I need, not sure if @Guts will be interested in doing anything with it, but here's the dependency if anyone wants to have a play (normal use at your own risk disclaimers apply)

I've updated the PR over on the RSS plugin repo - I'm not sure there is a neat solution upstream on the RSS plugin, but I might have missed something. I'm sure any thoughts would be helpful!

It must be fixed in the RSS plugin – let's hope it will be!
