On the Lua side, you'll have to pass strings so your example works, as tables like those in setuphead({somehead}, {somesettings}) are actual Lua tables and follow Lua, not TeX, rules (see e.g. Lua reference in https://www.lua.org/manual/5.4/ or, better, CLD manual in http://www.pragma-ade.nl/general/manuals/cld-mkiv.pdf): \starttext \startluacode --First example for m = 1, 3 do context.setuphead({'chapter'}, {before='hello'}) context.startchapter({title="I'm a chapter!"}) for i = 1, 3 do context.input("knuth") end context.stopchapter() end --Second example --We'll pass some strings to TeX local nice = "ConTeXt is love, ConTeXt is life" local somehead = 'chapter' local sometext = 'vallejo-trilce-es' context.setuphead({somehead}, {before=nice}) context.startchapter({title=somehead}) context.input(sometext) context.stopchapter() \stopluacode \stoptext I hope examples help.

Dear List,
I'm trying to mirror the context command `\setuphead[chapter][before=hello]` into lua with delayed typesetting of 'hello', but `\ctxlua{context.setuphead({'chapter'}, {before=context.delayed'hello'})}` does not have any effect. Could anyone help me on this? Thanks!
Best, Sylvain
