just lua code as placeholders for primitives will not show up in context
mkiv
\startluacode
local texsprint, ctxcatcodes = tex.sprint, tex.ctxcatcodes
local gsub, format, byte = string.gsub, string.format, string.byte
function commands.hexify(str)
texsprint(ctxcatcodes,(gsub(str,".",function(s) return
format("%0X",byte(s)) end)))
end
\stopluacode
\long\def\hexify#1{\ctxlua{commands.hexify([[#1]])}}
\hexify{I wonder why this is needed.}
btw, if your old module produces pdf and uses other \pdf... primitives
it's unlikely to work with mkiv anyway so you'd better check if it's
still needed
