Question about localleftbox/localrightbox/local*
Hi, when creating some boxes, specials recording the current values of localleftbox etc get inserted. Is there anybody on this list who actually uses those constructs? I am trying to figure out sensible semantics for them, and I have my doubts that the current semantics actually are fully operative for the purposes for which they have been created. So I'd be interested in hearing of any existing use cases/TeX code for them. Part of the reason is that they may interfere with normal typesetting in a manner similar to source specials in the current manner of implementation. Part of the reason is that the purpose for which I think they have been created (running quote characters) might be defeated by the current implementation if one unboxes material into a running paragraph. Analysing this would be facilitated by existing code making use of those features. Thanks, -- David Kastrup

I really believe you should ask these questions on an omega/aleph based mailinglist, not here. Luatex is only snapshots at this point (not even alpha status yet), so even if you can find example code, you will be unlikely to run it without errors. Please, lets not use this list to discuss whether or not Omega features live up to the desires of Omega users. Best wishes, Taco

I did that now, but the respective list traffic on the Omega and Aleph mailing lists does not really make me expect much of a response there (well, maybe from Idris).

Problem is that those are not just "Omega features" but also "Omega legacies". They have effects on the normal operation of LuaTeX even when not actively being used. While beating them into having no effect on typesetting when not actively used can probably be achieved without changing the overall semantics, this might quite complicate things. I consider it likely that some of the present semantics are mostly an implementation artifact and not actually beneficial. As far as I can discern, upstream Omega/Aleph are pretty much dead with regard to active user communities: it does not seem to make excessive sense for me to try to get any changes discussed or accepted into either project. And if I did, I have my doubts they would make it back into LuaTeX. And LuaTeX is the code base I am interested in. So I am both interested to know what LuaTeX (PDFTeX?) users would _want_ to use those features for (Idris? Do you happen to use any of the \local* stuff? Feel free to contact me offlist about this, maybe you are the only one), and what Omega/Aleph users already _did_ use them for, and in what manner. So I don't think it was wrong of me to ask on this list, but if you consider this topic disruptive, I'll be perfectly happy to receive any replies/communication about this off-list. -- David Kastrup
