Dear list, I have the following sample: \def\CheckUser{\cldcommand{sprint(tex.vrbcatcodes,os.resultof"whoami")}} \def\UserNumber{\processaction[\CheckUser][ousia=>1, unknown=>user unknown]} \starttext This is user \CheckUser\ with number \UserNumber. \stoptext which gives me the following output: This is user ousia with number user unknown. What am I doing wrong here? Many thanks for your help, Pablo -- http://www.ousia.tk

Many thanks for your help,
you output vrbcatcodes strings while you test using ctx catcodesn of course i'd use lua for all of it: \startluacode local user = "" local users = { ["oasi"] = 1, } function document.CheckUser() user = os.resultof("whoami") context.verbatim(user) end function document.UserNumber(name) context.verbatim(users[name or user] or 0) end \stopluacode \def\CheckUser {\ctxlua{document.CheckUser ()}} \def\UserNumber{\ctxlua{document.UserNumber()}} \starttext This is user \CheckUser\ with number \UserNumber. \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 -----------------------------------------------------------------

Many thanks for your reply, Hans. I’m afraid that the user doesn’t get recognized (I corrected the user name above). Is there no way to do it with \processaction? Many thanks for your help, Pablo -- http://www.ousia.tk

The same applies to your examples because your test won’t work on our machines ;)

Only when you ensure the text you get from Lua has the normal cathode regime and when you special characters like \ in the result you have to convert them to \letterbackslash etc. which isn’t simpler than Hans solution. The advantage of Hans solution is that you don’t have to care about expansion. Wolfgang

You’re right, Wolfgang, I chose the wrong sample. The next one (AFAIK) should work on every OS: \startluacode local user = "" local users = { ["ousia"] = 1, } function document.CheckUser() user = os.resultof("echo ousia") context.verbatim(user) end function document.UserNumber(name) context.verbatim(users[name or user] or 0) end \stopluacode \def\CheckUser {\ctxlua{document.CheckUser ()}} \def\UserNumber{\ctxlua{document.UserNumber()}} \starttext This is user \CheckUser with number \UserNumber. \stoptext

The solution from Hans is great. The only issue there is that it is much harder to understand for me. Since this is a minimal part in a way more complex implementation (at least for me), I really need to use commands that I know what they do. Pure Lua code is totally unknown to me. I don’t have any background in programming. This is the reason why I asked about \processaction. Many thanks for your reply, Pablo -- http://www.ousia.tk

(Untested) Change `local user` by ~~~ userdata = userdata or {} userdata.user = "" ~~~ and all other occurances of `user` by `userdata.user`. Aditya

Many thanks for your reply, Aditya. I followed your instructions, but I’m afraid that it doesn’t work. I cannot say whether it is my fault, since this is all Greek to me. I tried a simpler approach (my guess, I discovered the existence of \executesystemcommand yesterday), which doesn’t work either: \def\Checkuser{\executesystemcommand{echo rightuser > tmp-yser.txt}} \def\CheckUser{\Checkuser\input tmp-yser.txt} \def\UserNumber{\processaction[\CheckUser][rightuser=>1, unknown=>user unknown]} \starttext This is user \CheckUser\ with number \UserNumber. \stoptext I don’t know why the \UserNumber command cannot process action and why the backslash after \CheckUser is required, since it seems to add an extra space. What am I doing wrong in the previous example? Many thanks for your help, Pablo -- http://www.ousia.tk
