I just tried to import the fontloader from 2019-01-03 into latex, and get on a simple document the error
(./test-utf8.aux)error: ...ad/texmf/tex/luatex/luaotfload/fontloader-2019-01-03.lua:23868: attempt to call upvalue 'getdirection' (a nil value) . \newpage ...k \@nobreakfalse \everypar {}\fi \par \ifdim \prevdepth >\z@ \vs... l.51 \end{document} I have no idea (yet) if this is latex specific or if it could affect context too but thought I better mention it. The line refers to this part of the code: pardirstate=function(start) local nxt=getnext(start) local dir=getdirection(start) --<-- if dir==lefttoright then return nxt,1,1 -- Ulrike Fischer https://www.troubleshooting-tex.de/ ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________
