ABSTRACT
========

The `footnote` package by Mark Wooding (`1997/01/28` `1.13`)
allows to gather footnotes (`\begin{savenotes}`) and later insert
them (after `\end{savenotes}`) at the bottom of the page, even
if the intervening material consists of tabulars, minipages or
framed contents for example. One can also use the
`\savenotes/\spewnotes` syntax.

Also, `footnote.sty` provides a `footnote` environment which
allows to insert verbatim material.

Earlier releases of the present `footnotehyper` package added
patches for `hyperref` compatibility and some bugfixes, addressing
in particular the incompatibility with `color/xcolor`, and with
`babel-frenchb`, and also fixing the `footnote` environment with
optional argument `[NUM]`. Since `v0.99` all macros are defined
internally and the `footnote` package is not loaded at all.

The same user interface is kept. Since `v1.0` it is possible to
use `footnotehyper` also in absence of `hyperref` or when the latter is
loaded with its `hyperfootnotes=false` option. The order of loading of
`footnotehyper` and `hyperref` is inconsequential.

INSTALLATION
============

To extract the package (.sty) and driver (.tex) files from
footnotehyper.dtx:

- if footnotehyper.ins is present:   etex footnotehyper.ins
- without footnotehyper.ins:         etex footnotehyper.dtx
- or run latex or pdflatex directly on footnotehyper.dtx

At least three ways to produce footnotehyper.pdf (method (1) is
preferred):

1. latex footnotehyper.tex (twice), then dvipdfmx
2. pdflatex footnotehyper.dtx (twice)
3. latex footnotehyper.dtx (twice), then dvips, then ps2pdf

Method (1) produces the smallest pdf files.
Options can be set in footnotehyper.tex:

- scrdoc class options (paper size, font size, ...)
- with or without source code,
- with dvipdfmx or with latex+dvips or pdflatex.

Installation:

    footnotehyper.sty    -> TDS:tex/latex/footnotehyper/footnotehyper.sty
    footnotehyper.dtx    -> TDS:source/latex/footnotehyper/footnotehyper.dtx
    footnotehyper.pdf    -> TDS:doc/latex/footnotehyper/footnotehyper.pdf
    README.md            -> TDS:doc/latex/footnotehyper/README.md

The other files may be discarded.

\begin{abstract}
The `footnote` package by \textsc{Mark~Wooding} (`1997/01/28` `1.13`)
allows to gather footnotes (`\begin{savenotes}`) and later insert
them (after `\end{savenotes}`) at the bottom of the page, even
if the intervening material consists of tabulars, minipages or
framed contents for example. One can also use the
`\savenotes/\spewnotes` syntax.

Also, `footnote.sty` provides a `footnote` environment which
allows to insert verbatim material.

Earlier releases of the present \fnh package added
patches for `hyperref` compatibility and some bugfixes, addressing
in particular the incompatibility with `color/xcolor`, and with
`babel-frenchb`, and also fixing the `footnote` environment with
optional argument `[NUM]`. Since `v0.99` all macros are defined
internally and the `footnote` package is not loaded at all.

The same user interface is kept. Since `v1.0` it is possible to
use \fnh also in absence of `hyperref` or when the latter is
loaded with its `hyperfootnotes=false` option. The order of loading of
\fnh and `hyperref` is inconsequential.

\section{Usage}

Since |v0.99|, \fnh does not
load package
|footnote.sty|\footnote{\url{http://ctan.org/pkg/footnote}}
anymore, and is even incompatible with it at it uses the same user
interface.

Since |v1.0|, \fnh is usable also in absence of |hyperref| or when
the latter was passed |hyperfootnotes=false| option.

Version |v1.1| fixes a bug which arose when |savenotes| environment was used
\emph{inside} a minipage: footnotes were disappearing!%
%
\footnote{Thanks to François Pantigny for reporting the bug.}
%
See related remarks at end of \autoref{sec:notes}.

The package thus provides:
\begin{itemize}
\item a |savenotes| environment which re-routes footnotes and delivers them at
  the end (there is also the |\savenotes/\spewnotes| syntax; it does create a
  group like the environment),
\item |footnote| and |footnotetext| environments to allow footnotes
  with verbatim material.
\end{itemize}

But the constructability of the |footnote/footnotetext| environments depends
on how |\@makefntext| has been customized by the class or other packages; a
warning is issued if the situation appears to be desperate.\footnote{original
  |footnote.sty| could end up in a low level \TeX\ error.}

It should be recalled that in case of |\footnotemark[N]| and
|\footnotetext[N]{...}| mark-up |hyperref| creates no hyperlink. This is not
changed by \fnh and applies also to the |\begin{footnotetext}[N]| case.
Without optional argument the link is created, and the link is created also
for |\footnote[N]| or |\begin{footnote}[N]|.

This package does not handle especially floating environments, except that one
can always surround them in the source in a |savenotes| environment and one
knows that the footnotes will be delivered at the |\end{savenotes}|\dots which
may well be one page earlier than the actual location of the floating material
in the produced document !

Environments typesetting multiple times their contents are the most hostile to
footnotes. Currently, \fnh only handles especially the |amsmath|
environments (as in |footnote.sty|.)

Finally there is a |\makesavenoteenv| command which takes as
argument an environment name and patches it to do the
|\savenotes/\spewnotes| automatically.%
\begin{footnote}
  For the
record the syntax is either |\makesavenoteenv{foo}| which patches
environment |foo| or |\makesavenoteenv[bar]{foo}| which defines
environment |bar| as this patched version of |foo|.
\end{footnote}
It is safer to avoid it, as
one never knows what happens with such patches: for example the |[H]|
specifier provided by the |float| package overwrites the |\end{table}|
definition during the execution of |\begin{table}|\dots !

\begin{savenotes}
\begin{framed}
\DeleteShortVerb{\|}\MakeShortVerb{\*}%
{\centering
  \begin{tabular}{|c|c|}
    \hline
    \strut Inside\footnote{Notice that as  frame
      extended to the next page,
      the end of the *savenotes* environment delivered its
      footnotes only here.} a & tabular\begin{footnote}Alternatively a
      *\savenotes/\spewnotes* pair
      could have been used.\end{footnote}\\\hline
\end{tabular}\par}
\DeleteShortVerb{\*}\MakeShortVerb{\|}%
An example:
\begin{verbatim}
\begin{savenotes}
\begin{framed}
  Please refer to the documentation of the |footnote| package.%
  \footnote{\url{http://ctan.org/pkg/footnote}}

  Particularly you may check its |savenotes| environment.%
  \footnote{It doesn't bring any
  feature to especially handle the issues related to footnotes in floating
  environments, though.}
\end{framed}
\end{savenotes}
\end{verbatim}
and the present frame has \cs{footnote}'s from inside a |tabular| and is
inside a |savenotes| environment.%
\begin{footnote}
  Here is an issue which has nothing (as I finally figured out) to
  do with |footnote|, and only indirectly with \LaTeX: if you embed
  a \emph{full-width} minipage (with initial \cs{noindent}) in any
  environment not doing \cs{ignorespacesafterend}, be careful to add
  a \% either immediately after the |\end{minipage}| (or a |\relax|
  or a |\par|) or after the surrounding environment |\end{foo}| or
  use |\end{minipage}\end{foo}| else the output may have an extra
  blank line if the source has a blank line after the |foo| environment.
  Here is a typical example, with a |tabular| rather:
  \makeatletter

  \medskip\noindent\hspace{1cm}\begin{minipage}{\dimexpr\linewidth-1cm}%
  \def\MacroFont{\baselineskip10pt\relax}%
\begin{verbatim}
\newenvironment{foo}{}{}

\noindent\begin{tabular}{p{\dimexpr\linewidth-2\tabcolsep\relax}}
  A\dotfill B
\end{tabular}

C

\begin{foo}
\noindent\begin{tabular}{p{\dimexpr\linewidth-2\tabcolsep\relax}}
  A\dotfill B
\end{tabular}
\end{foo}

C
\end{verbatim}\end{minipage}\par\medskip

  If you try it out you will see an extra blank line in PDF output above the
  second C. Starting with |v0.99| the |\end{savenotes}| emits an
  \cs{ignorespacesafterend} which avoids this generic \TeX/\LaTeX\
  problem. For good measure there is now an \cs{ignorespaces} in
  |\begin{savenotes}|.
\end{footnote}
Let's test an
|amsmath| environment with |\intertext|. As
\begin{align}
  E&=mc^2\;,
\intertext{was too easy\footnote{There is also $E=h\nu$.}, let's
  try:}
  a^n + b^n &=c^n\;.
\end{align}
And a footnote with some verbatim material%
\begin{footnote}
  \verb|&$^%\[}$|
\end{footnote}.
\end{framed}
\end{savenotes}

The last one was coded as:
\begin{verbatim}
And a footnote with some verbatim material%
\begin{footnote}
  \verb|&$^%\[}$|
\end{footnote}.
\end{verbatim}
Now some use of |\footnotemark|\footnotemark\ followed by a |footnotetext|
environment.
\begin{footnotetext}
  This one uses the normal footnote counter and the hyperlink works.
\end{footnotetext}
And use of |\footnotemark[99]|\footnotemark[99] in association with a
|footnotetext| environment using the same optional argument |[99]|.
No hyperfootnote link was inserted.%
\begin{footnotetext}[99]
  |hyperref| creates no hyperlink in this case, or in the
  |\footnotemark[N]/\footnotetext[N]{<foo>}| case. It does when
  the |[N]| is absent or when it is used with a |\footnote| command
  (or a |footnote| environment.)

  By the way, \fnh |v0.9f|'s |\footnotetext[N]| and |\begin{footnotetext}[N]|
  each had a bug and they were unusable \emph{inside} the |savenotes|
  environment. There was no issue \emph{outside}.
\end{footnotetext}
And a final footnote, done with |\begin{footnote}[57]|%
\begin{footnote}[57]\csname @minipagetrue\endcsname % to reduce
                                % framed inserted vertical spacing
  \begin{framed}
    \noindent\fnh works since |v1.0| also in absence of |hyperref| or when the
    latter was passed |hyperfootnotes=false| option.
  \end{framed}
\end{footnote}.
There is no problem with the hyperlink, then.

\section{Notes}\label{sec:notes}

A few items worth of mention:
\begin{itemize}[nosep]
\item the |footnote| package patches the \LaTeX\ kernel |\parbox|.
  \fnh doesn't (but the code can be found commented-out at the
  end of the present file).
\item the |footnote| package defines a |minipage*| environment
  which is |minipage| patched by |\makesavenoteenv|, \fnh doesn't.
\item the |footnote| environment from |footnote.sty| does a
  |\leavevmode\unskip| which \fnh doesn't: hence if one locates
  |\begin{footnote}| at start of a line in the \LaTeX\ source, one will
    typically need a \% at end of text on previous line to avoid the
    end-of-line space.
\item the |hyperref| package inserts no hyperlink in case of
  |\footnotemark[N]/\footnotetext[N]|. This is not modified by \fnh.
\item side-note: there is an interference between |hyperref| and |frenchb|
  regarding the footnote marker when using the syntax |\footnotemark[NUM]|.
  For the record here is a patch (last tested briefly with
% PUTAIN BORDEL ! LaTeX Error: Text for \verb command ended by end of
% line. À CHAQUE FOIS ÇA M'AGAÇE. Bon, je n'ai pas mon patch habituel ici.
  |hyperref 2016/06/24 v6.83q| and |frenchb 2017/01/30 v3.2g|):

\end{verbatim}
% \endgroup
\item some environments typeset multiple times their contents,
  which causes issues; \fnh takes provisions only to handle the
  |amsmath| measuring step.
\item
  \LaTeX2e has some features when using footnotes in |minipage|'s
  which are themselves in a |minipage| which may also have footnotes externally
  to the internal minipages... try it out with some |\fbox|es around the
  sub-|minipages|, to see.

  \fnh behaves like original package |footnote| in such contexts. Only
  reasonable usage seems to embed the entire contents of the external minipage
  in a |savenotes| environment. But there will anyhow be collisions of the
  alphabetic enumerations. These collisions are there with or without \fnh (or
  |footnote.sty|.) I did not make any attempt, nor intend to in future, to
  address in an automatized manner these problematic contexts.

%   We now take care of |footnote.sty|'s |footnote| environment. The original
%   \cs{fn@endfntext} is lacking a \cs{fn@endnote}, and this meant that
%   |footnote.sty| was incompatible with |color/xcolor| packages. Also this
%   \cs{fn@endnote} was |\let| to |\color@endgroup| which is wrong.
%
%   Furthermore, independently of presence of the |\color/xcolor| issue, the
%   |footnote.sty|'s |footnote| environment raised an error if used with an
%   optional argument. |v0.9f| addresses this issue.
%
%   The |footnotetext| environment adds a complication, in case of optional
%   argument we should not try to set up a link due to the fact that |hyperref|
%   does not support it for the |\footnotemark[N]/\footnotetext[N]| syntax.
%   And we need to make sure that the |footnote| and |footnotetext| environments
%   obey the |\savenotes/\spewnotes| mechanism.
%
%   To handle all of this we code things completely differently from
%   |footnote.sty|.
% 
%   The |v0.9f| |\begin{footnotetext}[N]| inside |savenotes| tried to create
%   an hyperref target. Fixed for |v0.99|.
%
%   Note: the |footnote.sty| code did a |\leavevmode\unskip| at entrance of
%   |footnote| environment, which \fnh has not kept.
