Re: [NTG-context] What is the luatex version of \pdfescapehex
Sorry to my previous posts. I found a LaTeX package named pdftexcmds and the lua script works just fine. ___ 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://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

Yes, \pdffilemoddate, \pdffilesize, \pdfmdfivesum are kind of disabled as well,
I'm not familiar with lua at all, so I don't know how to replace them with the
lua version. I did change your code format("%0X",byte(s)) with
format("%s",byte(s))
and it worked as \pdfescapename. I hope I'm not too wrong.
Anyway, my ancient module just write directly with pdfobj, I just commented
the /ModDate parameters and seems just fine now.
I think I really need to learn some lua. Thank you again for your time.

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

[NTG-context] What is the luatex version of \pdfescapehex
Hi, I've written a very old module which used a lot of pdf primitives like \pdfescapehex and \pdfescapename etc. and it turns out not they don't work in mkiv. So I just want to know are there any alternatives? TIA -- Best Regards Chen Zhi-chu Chen | Shanghai Synchrotron Radiation Facility No. 2019 | Jialuo Rd. | Jiading | Shanghai | P.R.
