I have a problem with hyperref, longtable, appendix and babel (spanish) all together. TeX does not compile, with the following error:

! Argument of \@let@token has an extra }.
<inserted text>
                \par
l.111 1
       64700 & (1, 13, 13725) & (2, 2, 2745), (2, 3, 0), (3, 1, 0) \\
?

An example code to reproduce the error:

Remarks:

  1. Removing hyperref solves the problem (but also removes hyperlinks, of course).

  2. Using \chapter*{Longtable example} instead of \chapter{Longtable example} also compiles with no errors.

  3. Changing babel to english also works.

  4. The most curious thing: it was working before I updated my machine! Now, I installed latest version, i.e MiKTeX 2.9 (previously, I had v2.8) and updated all packages and the problem appeared.

I would appreciate any solution, I think this is a new error because of two things: firstly, I couldn't find anything similar in Google and secondly, it was working with previous versions of the packages and/or MiKTeX.

Extra info: OS Windows 7 x64bits, MiKTeX 2.9, all packages are updated to the latest versions. Let me know if you need more information.

remove the .out file and add

\usepackage[T1]{fontenc}

Like many accemted related problems things are better if T1 is used.

longtable is not actually related, you can delete the table with the same problem, but the hyperref bookmark file is very confused over \'{e} for some reason

\BOOKMARK [0][-]{Ap\unhbox \voidb@x \bgroup \let \unhbox \voidb@x \setbox \@tempboxa \hbox {e\global \mathchardef \accent@spacefactor \
spacefactor }\accent 19 e\egroup \spacefactor \accent@spacefactor \futurelet \@let@token ndice.alph1.Alph1}{Ap\351ndice Longtable examp
le}{}% 2

Note that you should not place longtable in a center environment.

  • It seems it doesn't work if inputenc is set to utf8. Do you understand why? (the whole matter revolves around \spanishappendixname). – user4686 Jan 12 '15 at 21:47
  • Adding \usepackage[T1]{fontenc} worked for me. Thanks! – Mariano Jan 13 '15 at 14:14
  • Note: I noted the known problem of bad quality fonts with T1 fontenc. To solve that I installed "cm-super" package and I had to add the "-Pcm-super" switch in "dvi2ps". – Mariano Jan 13 '15 at 15:02

The problem is very similar to How to make appendix and hyperref packages work together with cyrillic (non ASCII) characters?

\documentclass[12pt,a4paper,twoside,openright]{book}
\usepackage[latin1]{inputenc}
\usepackage[spanish]{babel}
\usepackage[titletoc]{appendix}
\usepackage{longtable}
\usepackage[hidelinks]{hyperref}

\makeatletter
\let\oriAlph\Alph
\let\orialph\alph
\renewcommand{\@resets@pp}{\par
  \@ppsavesec
  \stepcounter{@pps}
  \setcounter{section}{0}%
  \if@chapter@pp
    \setcounter{chapter}{0}%
    \renewcommand\@chapapp{\appendixname}%
    \renewcommand\thechapter{\@Alph\c@chapter}%
  \else
    \setcounter{subsection}{0}%
    \renewcommand\thesection{\@Alph\c@section}%
  \fi
  \if@pphyper
    \if@chapter@pp
      \renewcommand{\theHchapter}{\theH@pps.\oriAlph{chapter}}%
    \else
      \renewcommand{\theHsection}{\theH@pps.\oriAlph{section}}%
    \fi
    \def\Hy@chapapp{appendix}%
  \fi
  \restoreapp
}
\makeatother


\begin{document}
\frontmatter
\tableofcontents
\mainmatter
\chapter{Chapter 1}
   Chapter text
\begin{appendices}
\chapter{Example}
x
\end{appendices}

\backmatter
\end{document} 

If you remove the code between \makeatletter and \makeatother, the problem can be reproduced.

Of course, loading \usepackage[T1]{fontenc} is recommended for Spanish.

  • this makes it work with utf8 encoding too which \usepackage[T1]{fontenc} by itself does not. – user4686 Jan 12 '15 at 21:51
  • @jfbu Yes, you are right. – egreg Jan 12 '15 at 21:54
  • The maintainers of appendix package should presumably incorporate this bug fix. – user4686 Jan 12 '15 at 21:57
