Package: texlive-latex-extra
Version: 2009-10
Severity: normal
Tags: patch

Near beginning of ucshyper.sty:

\ifx\pdfoutput\undefined
  \PackageWarning{ucshyper}{ucshyper needs to be run with
    pdflatex.\MessageBreak Disabling functionality}%
  \expandafter\endinput\fi

This is buggy in several ways.

1) If another package loaded before ucshyper has used \@ifundefined
   to test the value of pdfoutput, then it is redefined to \relax
   instead of \undefined, and the above test will take the wrong
   branch.

2) Even if 1) is fixed, this tests whether the TeX implementation
   running is pdfTeX, while what it probably was intended to test for
   is whether the output produced is PDF... In other words, this test
   will not issue the warning if pdftex is running in DVI output mode;
   this is what happens in Debian when one runs /usr/bin/tex or
   /usr/bin/latex.

E.g. this document:

\documentclass{article}
\usepackage{ucshyper}
\begin{document}
foo
\end{document}

leads to this (La)TeX output (when run with plain latex):

LaTeX2e <2009/09/24>
(...)
Package hyperref Warning: Wrong driver `hpdftex.def';
(hyperref)                pdfTeX is not running in PDF mode.
(hyperref)                Using default driver.

*hyperref using default driver hdvips*

(...)

! Undefined control sequence.
\pdfstringdef ...@pdfstringtrue \PrerenderUnicode 
                                                  {#2}\endgroup \fi \ucshype...
l.5 \end{document}
                  
? 


Luckily (as you probably already know), the ifpdf package takes care
of these details for you, so the above code should be replaced by
something like:

\RequirePackage{ifpdf}
\ifpdf\else%
\PackageWarning{ucshyper}{ucshyper needs to be run with
    pdflatex.\MessageBreak Disabling functionality}%
  \expandafter\endinput\fi


See /usr/share/doc/texlive-doc/generic/FAQ-en/html/FAQ-ifpdf.html and
/usr/share/doc/texlive-doc/latex/oberdiek/ifpdf.pdf for more details.


However, there is a third issue even with 1) and 2) solved.


3) ucshyper does not actually need the output mode to be PDF, nor the
   TeX implementation to be pdfTeX. I just _removed_ the above test,
   as well as the following line:

\RequirePackage[pdftex,unicode]{hyperref}

and then I produce DVI with hyperref's "dvipdfm" option (driver
hdvipdfm), run it through dvipdfm and ucshyper still does its job like
a charm. For example this document:

\documentclass{article}
\usepackage[utf8x]{inputenc}
\usepackage[dvipdfm,bookmarks=true,unicode=true]{hyperref}
\usepackage{ucshyper}
\begin{document}
\section{\texorpdfstring{\ensuremath\lambda{}}{λ}}
\end{document}

latex it, run dvipdfm over the dvi, and the \lambda looks fine in
evince's side panel (Index).


So possibly this test should be changed to something like:

\ifdefined\PrerenderUnicode\else%
\PackageWarning{ucshyper}{ucshyper needs to be run with
    inputenc utf8x.\MessageBreak Disabling functionality}%
  \expandafter\endinput\fi

_and_ still remove the

\RequirePackage[pdftex,unicode]{hyperref}

line so that users can choose their own hyperref driver freely. Maybe
add instead:

\ifdefined\hypersetup%
 \hypersetup{unicode=true}%
\else%
  \PackageWarning{ucshyper}{ucshyper needs to be loaded after
      hyperref.\MessageBreak Disabling functionality}%
    \expandafter\endinput%
\fi%

I'd be tempted to promote the warnings to errors, actually.

Dear bug submitter,

the bug you have submitted against one of the TeX packages concerns
not the Debian packaging of TeX Live, nor the upstream TeX Live 
distribution itself, but Up-upstream, the original author of
the respective package.

TeX Live only collects what authors provide.

Thus, neither we, the Debian TeX Team, nor the Upstream TeX Live team
can fix anything regarding this bug.

Furthermore, the bug you have reported is rather old.

We suggest you to do the following:
* verify that the bug is still present with current TeX Live (2013)
  installation on Debian
* if yes, please report the bug to the *original* author of the TeX
  package, and *not* to upstream TeX Live nor Debian

Other ways to deal with these bugs are requesting help from TeX experts,
your local TeX consultant, or local TeX User Groups. One good place to
ask questions is the newsgroup comp.text.tex, or the StackExchange
website http://tex.stackexchange.com


Thanks a lot for your understanding

Norbert
