Dear list, using current latest (2022.10.22 11:23), I have the following sample: \starttext \doifelse{\jobname}{a} {yes}{no} \jobname \startluacode if tex.jobname == "a" then context("yes") else context("no") end \stopluacode \stoptext I get "no" as in TeX and "yes" with Lua, being "a.tex" the source file. The TeX conditional used to work before. Am I missing something or have I hit a bug? I’m on Linux64 (if this may be relevant). Many thanks for your help, Pablo

Are you sure the check worked in the past? The content of \jobname has catcode 12 while you "a" you check against has catcode 11, and even when \jobname result in "a" they are different because the catcodes differ. You can see the same result in the example below where the second check compares two a with different catcodes (11 and 12) while the first check has the same catcode (11) for both a's. \starttext \edef\A{a} \edef\B{a} \ifx\A\B yes \else no \fi \begingroup \catcode`a=12 \gdef\B{a} \endgroup \ifx\A\B yes \else no \fi \stoptext Wolfgang

Many thanks for your reply, Wolfgang. I thought this used to work before. Now I realize I have to check the use of \doif{\jobname} and \doifelse{\jobname} in all my documents.
The content of \jobname has catcode 12 while you "a" you check against has catcode 11, and even when \jobname result in "a" they are different because the catcodes differ.
I see now. Not that I fully understand what catcodes are, but \doifsamestringelse should be what I have used here (as suggested in https://wiki.contextgarden.net/System_Macros/Branches_and_Decisions#.5Cdoifs...). Just a final question: \doif compares both strings and catcodes and \doifsamestring compares only strings. Or am I missing something here too. Many thanks for your help, Pablo

I’m on Linux64 (if this may be relevant). More relevan tis that you'r on TeX where catcodes matter (here letter vs other)
\doifelse{\inputfilebarename}{oeps} {yes}{no} \doifelse{\detokenize\expandafter{\jobname}}{\detokenize{oeps}} {yes}{no} Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------

Many thanks for your explanation, Hans. I think I have to start studying basic notions in TeX. Many thanks for your help again, Pablo
