[patch] Add footnote when exporting links in LaTeX

[patch] Add footnote when exporting links in LaTeX

Hi!

When exporting to LaTeX, links are exported using \href. These are
completely invisible if the document is printed out. I consider this a
problem.

I think a good solution is to add a footnote with the link, in addition
to the \href. I've added a patch with this (tiny) change.

Subject: [PATCH] Add footnote when adding a link in ox-latex

Links in LaTeX-documents are also added in verbatim as a footnote, so it
is visible on paper.

Hej Lars,

Thanks for your patch.

It's easy enough to fix in latex.  Here's a not quite trivial solution
I've used for letters.

    \documentclass{scrartcl}
    \usepackage{url}
    \usepackage{hyperref}
    \usepackage[para,flushmargin]{footmisc}
    \makeatletter
    \Urlmuskip = 0mu plus 1mu
    \renewcommand\@makefntext[1]{%
      \hspace*{-2em}
      \parindent 0em
      \noindent
      \hb@xt@ 2.65em{\hss %  There's the option of putting \hss before
        \bfseries{\@thefnmark}. }%       or after \@thefnmark, aligning the footnote
      #1}%                  marks to the right or to the left, respectively
    \addtokomafont{footnotelabel}{\bfseries}
    \def\myurl#1{\setbox0\vbox{\hsize.5\maxdimen
    \url{#1}\par
    \setbox0\lastbox
    \global\setbox1\hbox{\unhbox0\unskip\unskip\unpenalty}}\unhbox1}
    \let\ohref\href
    \newcommand\fnurl[2]{\ohref{#2}{#1}\footnote{\myurl{#2}}}
    \renewcommand{\href}[2]{\fnurl{#2}{#1}}
    \makeatother
    \begin{document}
    foo \href{http://orgmode.org}{bar}
    \end{document}

We shouldn't hardcode this behavior.

Indeed we should not!  I use LaTeX (beamer) to create slides which have
links I can click on during lectures.  I would hate having footnotes for
all of these...

However, I can see the validity of Lars's use case so it would be nice
to have an option for this.  My approach is to put the link in a
footnote directly and not in the text if it's a document I intend to
print...
