While working on #pdf4anki integrated the feature of automatically adding opinionated #CSS with #cheerio to the initial #HTML file. This had the unknown side effect of destroying all the self-closing HTML tags, thus breaking the pattern matching.
The fun of taking apart the code to #debug this issue.
Just published the preliminary tool #pdf4anki on #codeberg
https://codeberg.org/barefootstache/pdf4anki
It mainly describes how to do it and is a semi-automation tool to get PDFs into #anki.
In the current version one will still need to modify the pattern constant in the clean-html.js file to align with the PDF in use.
