I am trying to automatically create a summary section/subsection at the end of a chapter/section, by marking text within the main text as part of the summary. Is there a package that does that?

I am trying to do this manually. The text in the summary section/subsection is copied from marked text within the main text. I used the collect package to do that (inspired from Gonzalo's answer).

I'm having a few issues so far:

  • Text within the collect* environment is placed within its own paragraph in the main text.
  • The beforecol and aftercol parameters of the collect package are separated from the text entry with a \par token, even when I do not provide it explicitly. I do not want that. I want them to be part of the same paragraph, unless explicitly stated.
  • If I do not provide \par at the end of aftercol, the aftercol content and begincol content of the subsequent collection are merged into one.
  • I am not sure how to use \includecollection in an enumerate environment such that each \begin{collect*} ... \end{collect*} becomes an \item in enumerate. Right now, the whole collection is treated as one big \item.
  • Automation. I guess what I am really looking for is the ability to use something like \summary[Before text.][After text.]{Text within main text} which will typeset and collect the text within main text normally, collect the before after parts, and produce a summary section/subsection at the end of every chapter/section, where every \summary is an \item in an enumerate environment. This is the least of my concerns though. :-)

Below is what I have so far. The second summary subsection is what I would like to get.

\documentclass{article}
\usepackage{collect}
\usepackage{multicol}

I found that most of my issues could be solved by renewing the collect* environment and (a) disabling the use of the preenv and postenv arguments; and (b) removing the \par token at the end of the environment which meant that every call to collect* was placed within its own paragraph.

I probably broke every rule in the book, but it'll have to do for now!

Renewed collect*:

%% Renew collect* environment to ignore `preenv` and `postenv`, both in
%% the file collected and in the file typeset. Also, remove final `\par`
%% so that the environment content is not necessarily in its own paragraph.
\makeatletter
\renewenvironment{collect*}[5]{%
\global\toks@{}%
\def\CE@file{#1}%
\def\CE@preenv{#2}%
\def\CE@postenv{#3}%
\def\CE@prefileenv{#4}%
\def\CE@postfileenv{#5}%
\CE@get@env@body@start%
}{%
\CE@ensure@opened{\CE@file}%
\edef\@tempa{\csname CE@@\CE@file @out\endcsname}%
\immediate\write\@tempa{\CE@meaning\CE@prefileenv}%
% \immediate\write\@tempa{\CE@meaning\CE@preenv}%
\immediate\write\@tempa{\the\toks@}%
% \immediate\write\@tempa{\CE@meaning\CE@postenv}%
\immediate\write\@tempa{\CE@meaning\CE@postfileenv}%
\immediate\openout\CE@tmp@out=\jobname.tmp%
% \immediate\write\CE@tmp@out{\CE@meaning\CE@preenv}%
\immediate\write\CE@tmp@out{\the\toks@}%
% \immediate\write\CE@tmp@out{\CE@meaning\CE@postenv}%
\immediate\closeout\CE@tmp@out%
\@input{\jobname.tmp}%
% \par%
}
\makeatother

New summary environment:

Then, we can create our own environment and collection that takes the beforecol and aftercol arguments. Credits to Gonzalo for his excellent answer.

\makeatletter
\newenvironment{summary}[2]
  {\@nameuse{collect*}{thesummary}{}{}{\item #1}{#2}}
  {\@nameuse{endcollect*}}
\makeatother

\definecollection{thesummary} % Collect summary content here.

Summary in enumerate:

By preceding the beforecol argument (#1) with \item, the collected data are suitable for use in \enumerate and \itemize environments, like so:

  \begin{enumerate}
    \includecollection{thesummary}
  \end{enumerate}

It is not exactly what you asked, but probably you can adapt it to your needs:

\documentclass{article}
\usepackage{framed, blindtext}

%%%%%%%%%%%%%%%%
\newcommand\lorname{\mdseries\textit{List of recommendations:}}%list of recommendations
\newcommand\lorext{lor} % another aux-file is needed
\newcommand\lortmp{}
\newcounter{recommendations}
\newcommand{\Empf}[2][\empty]{%
  \textit{Recommendations
    \refstepcounter{recommendations}\therecommendations{}:}%
  \vspace{-0.75\baselineskip} \begin{framed} #2 \end{framed}%
  \ifx#1\empty\renewcommand\lortmp{\footnotesize #2 }\else\renewcommand\lortmp{\footnotesize #1}\fi%
  \addcontentsline{\lorext}{subsection}{\therecommendations\quad\lortmp}
}
\makeatletter
  \newcommand\listofrecommendations{%
    \footnotesize
    \section*{\lorname}
    \markboth{\lorname}{}
    \@starttoc{\lorext}
  }
\makeatother
%%%%%%%%%%%%%%%%%%%%%%%%%

\begin{document}

\section{whatever}
\label{sec:whatever}

\blindtext
\Empf{Remember this}
\blindtext
\Empf{Remember that}
\blindtext

\listofrecommendations{}

\end{document}

This is all Chinese to me! :-) Thanks for your help, but I have managed to achieve something closer to the desired outcome. I've just added my answer. –  sudosensei Apr 3 at 16:41
