I am trying to redefine the ’open_read_file’ callback.

In your case the function resolvers.openers.helpers.textopener() takes the place of the open_read_file callback. It can be found in data-tex.lua.
Shall I simply do something like this?
local function textopener(tag, filename, filehandle, coding) result = old_textopener(tag, filename, filehandle, coding) -- Do lots of things return result end
resolvers.openers.helpers.textopener = textopener
this is not the recommended way .. better do somethign like this: \starttext \startluacode function document.MyCharacterMess(str,filename) if file.nameonly(filename) == "ward" then str = table.concat(string.totable(str,"."), " + ") end return str end local textfileactions = resolvers.openers.helpers.textfileactions utilities.sequencers.appendaction(textfileactions,"system","document.MyCharacterMess") \stopluacode \input ward \input knuth \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
