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: - 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.

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. A later suggestion of the same is to let the package do nothing under Beamer class, and this is what |v1.1a 2019/11/07| does.} % 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]{}| 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|): % pour le cas où mis dans commentaires de code % \begingroup\makeatletter\let\check@percent\@gobble \begin{verbatim} \AtBeginDocument{% \let\@xfootnotemarkORIFB \@xfootnotemark \def\@xfootnotemarkFB {\leavevmode\unskip\unkern\,\@xfootnotemarkORIFB }% \ifHy@hyperfootnotes\ifFBAutoSpaceFootnotes \let\@xfootnotemark\@xfootnotemarkFB \fi\fi }% \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| when the |savenotes| environment is used \emph{inside} a minipage. 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. % \begin{macrocode} \DeclareOption*% {\PackageWarning{footnotehyper}{Option `\CurrentOption' is unknown}}% \ProcessOptions\relax % \end{macrocode} % \end{macro} % |v1.1a| lets the package abort under Beamer class and warn user. % \begin{macrocode} \@ifclassloaded{beamer} {\PackageWarningNoLine{footnotehyper}{This package is incompatible with the beamer class.
