Testing value of a \def
Hello, I'm trying to test whether value of \jobname is "Test"; I suppose it should be as the file name is "Test.mkiv". But the code: ---- \starttext \jobname \doifelse{\jobname}{Test}{Yes}{No} \def\T{Test} \ifx\jobname\T True\else False\fi \ctxcommand{doifelse("\jobname" == "Test")}{1}{0} \stoptext ---- yields "No", "False" and "1", so only the printed "1" is what I expect. Why \doifelse and \ifx are evaluated as false? Best regards, Lukas -- Ing.

I'm trying to test whether value of \jobname is "Test"; I suppose it should be as the file name is "Test.mkiv".
But the code:
---- \starttext \jobname \doifelse{\jobname}{Test}{Yes}{No} \def\T{Test} \ifx\jobname\T True\else False\fi \ctxcommand{doifelse("\jobname" == "Test")}{1}{0} \stoptext ----
yields "No", "False" and "1", so only the printed "1" is what I expect.
Why \doifelse and \ifx are evaluated as false?
The string from \jobname consists of catcode 12 letters while normal text consists of catcode 11 letters. If you need the name of the file use one of the commands below. \starttext \starttabulate \NC \tex{jobfilefullname} \NC \jobfilefullname \NC\NR \NC \tex{jobfilename} \NC \jobfilename \NC\NR \NC \tex{jobfilesuffix} \NC \jobfilesuffix \NC\NR \TB \NC \tex{inputfilebarename} \NC \inputfilebarename \NC\NR \NC \tex{inputfilerealsuffix} \NC \inputfilerealsuffix \NC\NR \NC \tex{inputfilesuffix} \NC \inputfilesuffix \NC\NR \NC \tex{inputfilename} \NC \inputfilename \NC\NR \stoptabulate \stoptext Wolfgang
Great, thank you!
