@UlrikeFischer also this time books (\chapter) have long names with optional short (in all cases) can we make the short ones appear in the pdf bookmarks outline (I'd do it but I'm scared of the tagging:)
@UlrikeFischer long I think, I was just looking on internet archive to see if there is a scan of the original but I only see digitised new printings, I'm sure I saw one somewhere before, bu go with long, I think
@DavidCarlisle this here could work (but only tested on a short example): \AddToHookWithArguments{cmd/chapter/before}{\def\ch@pt@c{\texorpdfstring{#3}{#2}}}
@UlrikeFischer You only need to add stuff to the .gitignore if you're irritated by the list of untracked/changed files in git status, as long as you don't really care about that untracked files don't really do any harm.
@PabloGonzálezL you were first one to try xetex since switched to 2024 and it was running fc-cache which times out. I am super important and not subject to time limits so the font cache built for me:-)
