Duplicate post summary in blog

[harrelfe]

In my blog at https://hbiostat.org/blog you'll see that the article summary for the most recently posted article is duplicated, with an extra entry at the top that does not contain the title, date, or author, and has reading minutes of 0. Here's key elements of my setup:

Any help appreciated.

I think the issue is very likely that we're matching some document / file in the file system that is empty (we read the description as rendered HTML out of the output file, so this would require us to both match an empty input file, but also then to somehow get fooled into using a wrong output file). I did make a change to simply ignore fully empty documents (documents with no metadata), which could potentially resolve this, though it would be great to get to the bottom of the mystery.

Can you remind me whether I could take a look at the repo to see if I could reproduce it locally and see if I can catch this one?

Yes, ! is a special YAML thing :( Let me see if I can improve that error message.

[harrelfe]

Quoting it got rid of the syntax problem:

listing:
  - id: post
    contents:
      - post/**/*.qmd
      - "!post/**/index.qmd"

But unfortunately the first 3 lines of the duplicated summary are still there with Quarto 1.2.205 on https://hbiostat.org/blog

Darn! I think the best next step might be for me to take a look locally if at all possible - any chance you could share a zip?

[harrelfe]

Here it is: https://hbiostat.org/attach/q.zip
You might take a quick look first at the differences between post/index.qmd and talk/index.qmd

I used to have contents: "*/*.qmd in post/index.qmd but that didn't seem to matter.

Thanks for looking into this.

[dragonstyle]

OK thank you this was great - thank you for sharing!

The issue is, as I suspect, that the post/index.qmd is being included in the listing- this is because the glob post/**/*.qmd means post then any qmd in any depth subdirectory (including a depth of 0). If you don't need this recursive behavior, you could change this to post/*/*.qmd and if you do need the recursive behavior, it could be post/*/**/*.qmd. I think with that change you should get back on track (and you can drop the whole !post... contents item).

This, of course, uncovered an issue with the way we resolve globs when reading listings - because we currently process each content glob independently, we aren't properly excluding files as we should when that exclude glob is in the list because we aren't treating contents like a merged list of globs. I've got a fix for this on the way.
