The update from asciidoc 9.x to 10.x has been a long standing fiasco. The initial release had quite a few bugs that completely blocked our usage and (as is the case for many Python projects) packaging has gotten harder as upstream tooling is less distro friendly. After an upstream minor release and several patch releases most of the major issues are resolved and I've cobbled together packaging that works. It has been in the [community-testing] repository for a while now and has a couple signoffs. I've also mentioned some of the differences in IRC, but I thought I would give a warning here — I'm about to move it to [community]. Many Arch packages have asciidoc as a makedepends=(). Most of these do not require it as a library and thus the API changes in 10.x will not be relevant, but they do use the CLI script for converting documentation to man pages. One of the major changes in 10.x relevant to other Arch packages is that these CLI scripts /usr/bin/{a2x,asciidoc}.py are no longer distributed with the .py extension, they are just plain /usr/bin/{a2x,asciidoc}. Many upstream projects have adopted this already, but there may be some that have not and will need patching. If you do run into trouble building anything, that is the most likely culprit and the first thing to search for and patch out of upstream code. Caleb
