Summary: - the "cause" of failure of sisu and hence live-manual to produce pdf output is that sisu's latex output is out of date and needs updating..., - I am on it and am making headway :-) - changes have not yet been uploaded upstream, I will report when they are.
The longer story :-) I thought it time to post an update since I am looking at this, though I have been procrastinating :-( A week ago I was back on a my old debian box, forgotten password reset and dist-updated. My assumption as to where the fault was likely to lie proved incorrect, 2 or three .sty files had moved, but they were all installed by sisu-pdf or sisu-complete and available on the system. So, ... minor surprise, Debian (testing/unstable at least) is using a newer version of texlive (2023) than NixOS (texlive 2022-final) and somewhere therein lies the problem, of the issue not having come up for me. sisu.spine the not-shared D lang version of sisu in its rewrite has more recently "developed" latex output and, though not developed or tested previously on texlive 2023 is not afflicted to the same extent as sisu.ruby that we fixing here. This meant, I had something to look at and could no minor (very incomplete) backporting for output and make headway in solving the sisu-pdf issue reported for live-manual pdf output. In short, progress has been made, I do have some output. Current status, though checking will be necessary, I do have portrait pdf output for languages other than Chinese, Japanese, Korean (are made to work in an updated way on sisu.spine.d i.e. not using CJK.sty whatever that sty that is claimed to be obsolete is called... have not looked at yet, but should be doable). For landscape pdf output, I expect the effort to be relatively minor, just it all takes a bit of time (especially with a procrastinator, I am plodding towards getting it done though). I will report again when I have got further or better yet, when I upload a first set of changes to sisudoc.org This bug, should be cross-assigned to sisu.
