I have this code in my 12 year old Tex files that I currently like to upgrade such that they work with lualatex. I load this code in order to fix a problem with marginnote and framed. Unfortunately I did not document which problem and how to show it.

% !TeX program = lualatex


    }% ifpdfoutput
}{}% ifpdftex


My first question is: Do I still need this?

Second question: How can I work around the problem with lualatex:

! Incomplete \iffalse; all text was ignored after line 14.

The error happens somewhere in the code. It worked with pdflatex.

    well the question is how \ifpdftex and \ifpdfoutput are defined in your code. (default definitions from \iftex wouldn't uses braces for the cases but \else and \fi. Aug 5 at 21:07
  • I updated the code. I seem to use the definitions of the ifpdf package. Aug 6 at 5:05

    no. The ifpdf package never defined such tests. If you previously used one of the koma classes you could have such tests but they have been removed/renamed. In any case they are useless here (as are the begingroup/endgroup). If your frame patch has some use, it can be done always. Aug 6 at 8:05
  • the posted code gives errors in pdflatex and luatex, please clarify your question so the example matches the problem description, working in pdftex and not in luatex Aug 6 at 9:09
  • I assume that I had never loaded marginnote, so that the code was always unused. Now I removed the code so that I do not need to correct it. Thanks anyway. Aug 8 at 20:40
