The Python-driven blog software Pelican https://getpelican.com now understands AsciiDoc3!

The required plugin asciidoc3_reader is waiting to be merged: https://github.com/getpelican/pelican-plugins/pull/1081 You can also find the sources here: https://github.com/asciidoc3/pelican-plugins/tree/asciidoc3_reader/asciidoc3_reader

The news need the extension ad3 (as in mytext.ad3) to be recognized by pelican - the very page you are reading just now is successfully produced in this way.
