LiquidTags.extendMarkdown() missing 1 required positional argument: 'md_globals'

I'm getting this error on a site created with blog-o-matic template.

...repeats for each document in content.

Versions:

• Python 3.10.8
• markdown 3.4.1

I don't know how to get the installed liquid_tags version, so can't tell if the fix in #20 is present.

I think I've got an older version of liquid tags. If I'm interpreting https://github.com/pelican-plugins/liquid-tags/pull/20/files#diff-64678f0e067a6e5b345f3dd61ee483febe3abcca283e00415117217081733ab3R89 lines 85/89 correctly what I have in my tree is old:

    def extendMarkdown(self, md, md_globals):
...snip...

So perhaps I've created an issue in the wrong project. If so, which is the right one? Pelican-plugins? Blog-o-matic? Elegant? I'm not sure how these relate to each other. I see there's peru for dependency management, which is new to me. Maybe I need to be leveraging it somehow. Anyway, if this is the wrong place, sorry for the noise, and please point me in the right direction. Thanks!

Yes, this is issue #19 that we have fixed in #20. Your setup is currently using new Pelican, new Markdown and old liquid-tags. The easiest way of getting out of this is pulling in old Markdown version:

pip install markdown==3.3.7

You can modify your requirements.txt to pin Markdown.

Of course the real question is why you end up with old liquid-tags. Apparently, blog-o-matic is using pelican-plugins repository, which has 2-year old liquid-tags. Pelican community started to move away from this repository into separate pelican-plugins organization with Pelican 4.5, released in 2020.

For me, this is blog-o-matic issue. Their configuration results in usage of outdated packages. They either need to pin Pelican and Markdown to pre-2020 versions, or they need to start using plugins from new repositories.

Ahh, thank you for the history and status quo change! I had completely missed the shift away from monorepo. I will redirect to blog-o-matic and related.
