Unexpected error when combining beamer + tabular + newif












7















The code is below:



documentclass[a4paper]{beamer}
usepackage[utf8]{inputenc}
title{Ok}
author{Me}
date{today}

newififok
oktrue

begin{document}

maketitle

begin{frame}
ifok
Hello
begin{tabular}{c}
ok \
end{tabular}
fi
end{frame}

end{document}


This small code piece makes pdflatex to outout (only last lines):



! Incomplete ifx; all text was ignored after line 19.
<inserted text>
fi
<*> ok.tex

?
! Emergency stop.
<inserted text>
fi
<*> ok.tex

! ==> Fatal error occurred, no output PDF file produced!


Any idea to fix this or should I throw out the use of newif?

          Beamer does lots of "interesting" re-arrangements of its inputs, you can use the [fragile] option on a frame so it uses a safer, slower, mechanism:



          documentclass[a4paper]{beamer}
          usepackage[utf8]{inputenc}
          title{Ok}
          author{Me}
          date{today}

          newififok
          oktrue

          begin{document}

          maketitle

          begin{frame}[fragile]

          ifok
          Hello
          begin{tabular}{c}
          ok \
          end{tabular}
          fi

          end{frame}

          end{document}

            Thank your very much. Maybe, a rule of thumb could be: if doesn't work as expected, use "fragile".
