If you only need the current section at the position where the test occurs, then you can try the following (beware this might not be canonical). ····· chaptertest.lua ·················································· local context = context local check_structure = function (s) context(s) local current = structures.sections.current() if current.userdata and current.userdata.location == "A" then context" is in chapter A" else context" is elsewhere." end end commands.checkstructure = function (s) check_structure(s) end ········································································ ····· chaptertest.tex ·················································· \ctxloadluafile{chaptertest} \unprotect \def\lookup#1{\ctxcommand{checkstructure\!!bs#1\!!es}} \protect \starttext \startchapter[title=foo] [location=A] \lookup{My dear something}\par \input knuth \stopchapter \startchapter[title=bar] [location=B] \lookup{My dear something}\par \input knuth \stopchapter \stoptext ········································································ For more info about the local structure you might want to have a look at table.print(structures.sections.current()) Regards Philipp > > Is this possible?
