Footnote problem using paracol package

Question

Look at this simple code:

\documentclass[12pt,a4paper]{article}
\usepackage[latin1]{inputenc}
\usepackage[german]{babel}
\usepackage{paracol}

\begin{document}

Hello world!\footnote{A simple footnote.}

\columnratio{0.1}
\begin{paracol}{2}
D1.1
\switchcolumn
This is a simple definition.
\end{paracol}

This is a simple sentence.\footnote{Another simple footnote!}

\end{document}

It's producing a totally weird output. (Sorry, I'm not allowed to upload an image.)

Why is the first footnote showing up right above the paracol environment? What am I doing wrong?

Answer 1

paracols ends the current page so places footnotes before starting its multicolumn layout.

If you don't want that you can redefine things so it just stores the footnote away and then you can retrieve it after the environment or anywhere else suitable.

\documentclass[12pt,a4paper]{article}
\usepackage[latin1]{inputenc}
\usepackage[german]{babel}
\usepackage{paracol}

\setlength\textheight{.3\textheight}

\makeatletter
\newbox\mybox
\def\pcol@makenormalcol{%
  \ifvoid\footins 
  \else
\global\setbox\mybox\box\footins
   \fi
\setbox\@outputbox\box\@holdpg
  \let\@elt\relax
  \xdef\@freelist{\@freelist\@midlist}%
  \global\let\@midlist\@empty
  \@combinefloats}

\makeatother

\begin{document}

Hello world!\footnote{A simple footnote.}

%\columnratio{0.1}% this generates an error
\begin{paracol}{2}
D1.1
\switchcolumn
This is a simple definition.
\end{paracol}
\ifvoid\mybox\else\insert\footins{\unvbox\mybox}\fi

This is a simple sentence.\footnote{Another simple footnote!}

\end{document}
