I have merged the last piece of the archetype refresh. If you can build from the latest source, please take it for a spin and report back. Else, wait for the release. Not sure when.
I have .md and .org files in my content. The newly created content is .org
I tried the example given in the PR to create .md files.
For that I changed the type of some of my posts to cool. The newsletter which was created listed only the titles of the cool markdown files.
The cool Org files which I have tagged with +#TYPE: cool and I tried also +#TYPE: "cool" were not listed in the newsletter.
BTW: it would be nice to create also new Org content using the archetypes.
Yes it was. Your question was “why was my org mode pages not picked up by the where” and I don’t know (I’m not familiar with org mode front matter syntax), but it is not relevant to this topic.
