hyperref support for endnotes
Ulrich Dirr
some people recently had problems using hyperref with endnotes. I've
tried to help them. Maybe this could be some useful extension for
hyperref (the interface to work as an option like 'hyperendnotes' have
to be added).
I would welcome any comments on my attempt (Sebastian Rahtz or Heiko
Oberdiek???).
As it's more useful for endnotes---in contrast with footnotes---to have
links back I've tried to get this work too. BTW it seems to be necessary
to put something like \expandafter in front of \url to get this work
with endnotes.
My test file looks like this:
%%% snip
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\documentclass[pd
ftex]{article}
\usepackage{endnotes}
\usepackage{hyperref}
\usepackage{hyperendnote}
%\pdfcompresslevel=0
\begin{document}
\noindent
First endnote\endnote{\expandafter\url{http://www.google.com}.}.
\newpage
A page between two notes.
\newpage
\addtoendnotes{\newpage}% so both notes will be on separate pages
% for testing purpose
Another page with another endnote.\endnote{blabla two}
\newpage
blabla
\newpage
\theendnotes
\end{document}
%%% snip %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
The redefined macros in hyperendnote.sty:
%%% snip
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\newcounter{Hendn
ote}
\long\def\@endnotetext#1{%
\if@enotesopen \else \@openenotes \fi
\immediate\write\@enotes{\@doanenote{\@theenmark}}%
\begingroup
\def\next{\hyper@@anchor{Hendnote.\@theenmark}{#1}}%
% \@theenmark will be correct when <file>.ent is read in
% because \@theenmark is redefined in \theendnotes:
% [...] \def\@doanenote##1##2>{\def\@theenmark{##1} [...]
% The actual number was written as an argument of \@doanenote
% (e.g. \@doanenote {1}) to <file>.ent.
\newlinechar='40
\immediate\write\@enotes{\meaning\next}%
\endgroup
\immediate\write\@enotes{\@endanenote}}
\def\@endnotemark{\leavevmode\ifhmode

\ifhmode\spacefactor\@x@sf\fi\relax}
% original def
\def\enoteformat{\rightskip\z@ \leftskip\z@ \parindent=1.8em
\leavevmode\llap{%
\hyperlink{Hendnotepage.\@theenmark}{%
\hbox{$^{\@theenmark}$}}}}
% I prefer something like below.
% One weakness is that a user redefinition is only possible in
% combination with \makeatletter/\makeatother.
%\renewcommand{\enoteformat}{\rightskip\z@ \leftskip1em \parindent=0pt
% \parskip.5\baselineskip plus .5\baselineskip minus .5\baselineskip
% \leavevmode{\makebox[0cm][r]{%
% \hyperlink{Hendnotepage.\@theenmark}{%
% \hbox to1em{\@theenmark.\hfill}}}}}
\endinput
%%% snip %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
I'm not sure if all the stuff in \@endnotemark is necessary. I've just
naively stolen this code from hyperref.sty.
