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 ============ The recommended way is to first extract the package (.sty) and driver (.tex) files from footnotehyper.dtx via tex footnotehyper.dtx and then produce the documentation via latex footnotehyper.tex (twice) dvipdfmx footnotehyper.dvi It is also possible to produce simultaneously the package and the documentation via one of these two routes: pdflatex footnotehyper.dtx (twice) or latex footnotehyper.dtx (twice) dvips ps2pdf The method using the extracted file footnotehyper.tex produces the smallest pdf file and is the officially preferred one as it allows to set options in footnotehyper.tex to customize the footnotehyper.pdf file: - scrartcl 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.

This is a rather fragile step, and the next section discusses problems which may arise. \subsection{Potential difficulties with the footnote and footnotetext environments} What is discussed here only affects the \emph{environments} |footnote| and |footnotetext| not the macros \cs{footnote} and \cs{footnotetext}. \fnh inherits from |footnote| original package the aim to convert |\@makefntext| into two parts, the first one to be inserted at the start of a footnote in environment form, the second one (usually empty) at its end.% % \begin{footnote} \LaTeX\ inserts some stuff before and after the footnote text, even before handing it over as argument to \cs{@makefntext}. These tokens are currently hardcoded into the \fnh environments for footnotes. \end{footnote} % It thus hopes that the replacement text of |\@makefntext| contains only once its parameter token |#1|, and that it is used there unbraced. This is the case with the |article| class. Known bug (may be promoted to feature at some point): the analysis is done only once at begin document, whereas the |article.cls|'s redefines |\@makefntext| during execution of |\maketitle|. However, it does not look really urgent to support at all costs usage of the environment |footnote| in the |\author| etc... data which contributes to the |\maketitle| expansion.% % \begin{footnote} \phantomsection\label{fn:texperts}% \TeX perts note: |\def\FNH@prefntext{\@makefntext{}}| would make the footnote environment dynamically adjust to circumstances, when |\@makefntext| only adds some prefix and no postfix. In fact, this is (in a more complicated form for compatibility with |KOMA|-script and to obey the |FBFrenchFootnotes| setting and the additional extra stuff inserted by |babel-french| before and after) basically what is done by \fnh to handle |babel-french|. As it may cause instability if extra packages fiddle with |\@makefntext|, or |\@makefntext| is radically re-defined in some environments provided by the class, \fnh does not use this when its begin document analysis concluded the argument was used unbraced and at last position in replacement text of |\@makefntext|, but it freezes the found prefix. However, when it is concluded that probably |\@makefntext| has been redefined in an |\old@makefntext| way (for example, this is the case with |cleveref| package), then the |\def\FNH@prefntext{\@makefntext{}}| approach is taken, despite the risks inherent to it. You can provide your own custom definitions for \cs{FNH@prefntext} and \cs{FNH@postfntext}. Then add to the preamble \cs{footnotehyperparsefalse}. \end{footnote} Some seemingly innocent redefinitions such as the one of |beamer| which was last time I checked (that was in 2019): \begin{verbatim} macro:#1->\def \insertfootnotetext {#1}\def \insertfootnotemark {\@makefnmark } \usebeamertemplate ***{footnote} \end{verbatim} are not (easily) compatible with environment forms for footnotes allowing verbatim material, as they require fetching the footnote contents.% \footnote{%\phantomsection\label{fn:beamer}% test, ça marche! Since |v1.1a|, \fnh simply aborts under |beamer| class.} In case of such a problematic |\@makefntext| \fnh raises a warning, to explain that footnotes typeset using the environment forms will use a fall-back layout (inherited from the |article| document class). Footnotes using |\footnote| are not impacted by this. % See \ref{fn:beamer} % test, ça marche, aussi avec environnement Also \fnh emits some info message if |\@makefntext| was not as simple as expected but nevertheless there is some hope that the |footnote| and |footnotetext| environments will be fully functional. This is currently the case in presence of package |cleveref| (see the \TeX perts footnote \ref{fn:texperts}). You can turn off these messages by adding \cs{footnotehyperwarnfalse} to the document preamble. \subsection{Other potential or actual limitations} 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|.) \subsection{The \cs{makesavenoteenv} macro} Finally there is a |\makesavenoteenv| macro which takes as argument an environment name and patches it to do the |\savenotes/\spewnotes| automatically.% The syntax is either |\makesavenoteenv{foo}| which patches environment |foo| (since |1.1e|, via the hooks provided by \LaTeX\ since October 2020) to do automatically \cs{savenotes}/\cs{spewnotes}, or |\makesavenoteenv[bar]{foo}| which defines environment |bar| as |foo| inside a |savenotes| environment. With \LaTeX\ earlier than October 2020, the macro is the same as in the original |footnote| package and proceeds in a more brutal way than what is described in previous paragraph. 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!% % \footnote{By the way I have not checked if this |float| package feature behaves nicely, or has been updated to be compatible, with the \LaTeX\ hook mechanism of October 2020.} As another example, |\makesavenoteenv{tcolorbox}| with the original |footnote| package code breaks, but the new version activated with \LaTeX\ from October 2020 or later appears to work. \subsection{Example of output, and of input} \begin{savenotes} \begin{framed} \DeleteShortVerb{\|}\MakeShortVerb{\*}% {\centering \begin{tabular}{|c|c|} \hline \strut Inside\footnote{If the frame extends to the next page, the end of the *savenotes* environment delivers its intercepted footnotes only there.} a & tabular\begin{footnote}Alternatively a *\savenotes/\spewnotes* pair could have been used.\end{footnote}\\\hline \end{tabular}\par} \DeleteShortVerb{\*}\MakeShortVerb{\|}% Here is an illustrative example of usage of the |savenotes| environment: \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{% here is how to add anchor for hyperlink target: \phantomsection\label{fn:floats}% (this % to avoid space at start of paragraph) It doesn't bring any feature to especially handle the issues related to footnotes in floating environments, though.} \end{framed} \end{savenotes} Here is a link to an interesting footnote: \ref{fn:floats}. \end{verbatim} and the present frame has \cs{footnote}'s from inside a |tabular| and is inside a |savenotes| environment.% \begin{footnote}\phantomsection\label{fn:minipage}% (attention à l'espace) 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}\phantomsection\label{fn:verb}% The footnote environment allows verbatim contents: \verb|&$^%\[}$| \end{footnote}. \end{framed} \end{savenotes} The input for the footnote \ref{fn:verb} was coded as: \begin{verbatim} And a footnote with some verbatim material% \begin{footnote} The footnote environment allows verbatim contents: \verb|&$^%\[}$| \end{footnote}. \end{verbatim} Now some use of |\footnotemark| followed by a |footnotetext| (here is the mark: \footnotemark) environment.% attention! sinon espace extra % \begin{footnotetext} Notice that the hyperlinking works for |\footnotemark| associated to the environment |footnotetext|. \end{footnotetext} And use of |\footnotemark[99]| in association with a |footnotetext| environment using the same optional argument |[99]| (here is the mark: \footnotemark[99], and you can see it is not an hyperlink).% ! % \begin{footnotetext}[99] |hyperref| creates no hyperlink in this case, or in the |\footnotemark[N]/\footnotetext[N]{}| case. It does when the |[N]| is absent or when it is used with a |\footnote| command (or a |footnote| environment.) \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.% % \footnote{Oh, and don't forget to read this interesting footnote: \ref{fn:minipage} (just in case you skipped on first reading).} \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.

Only reasonable usage in case of nested minipages seems to use only a single top level (i.e. external) |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. \end{itemize} \StopEventually{\end{document}\endinput} \makeatletter \let\check@percent\original@check@percent \makeatother \newgeometry{left=4cm, hscale=0.72} \section{Implementation} \small \makeatletter \noindent \begingroup \topsep\MacrocodeTopsep \trivlist\parskip\z@\item[] \macro@font \leftskip\@totalleftmargin \advance\leftskip\MacroIndent \rightskip\z@ \parindent\z@ \parfillskip\@flushglue \global\@newlistfalse \global\@minipagefalse \ifcodeline@index \everypar{\global\advance\c@CodelineNo\@ne \llap{\theCodelineNo\ \hskip\@totalleftmargin}}% \fi \string\NeedsTeXFormat\string{LaTeX2e\string}\par \string\ProvidesPackage\string{\pkgname\string}\@percentchar\par \noindent\space [\pkgdate\space\pkgversion\space\pkgdescription]\par \nointerlineskip \global\@inlabelfalse \endtrivlist \endgroup \makeatother % The catcode hackery next is to avoid to have <*package> to be listed % in the commented source code... % (c) 2012/11/19 jf burnol ;-) \MakePercentIgnore % % \catcode`\<=0 \catcode`\>=11 \catcode`\*=11 \catcode`\/=11 % \let\relax % \def<*package>{\catcode`\<=12 \catcode`\>=12 \catcode`\*=12 \catcode`\/=12} % % %<*package> % \begin{macro}{no options} % The package has no options.
