Es gibt mit Markdown eine einfache Auszeichnungssprache für Text, die man mit pandoc in viele verschiedene Formate übersetzen kann.

While testing the Markdown files generated by pandoc in Hugo, I realized I had some duplicate content that was making the individual posts very difficult to read. After careful reading of the pandoc Manual I discovered to my sadness that there was no built-in way to remove the content I did not want 😉. The only option then was to write pandoc filters. Now pandoc has libraries that allow you to write filters in pretty much any modern language but out of the box, it supports filters written in Lua.

Bei Pandoc 3.4 gehören die Lua-Filter in den Unterordner filters, also z. B. ~/.local/share/pandoc/filters
