Automatic creation of own tocs

Question

Dear TeX(stackexchange) community, I'm trying to create automatically my own TOCs: using \keyword command I define the entries of my own toc list so that each belonging to same chapter will be printed at beginning of chapter using \listofkeywords.

There is a problem for first chapter: no .key1 file created and no toc printed. That's my MWE:

\documentclass[oneside,11pt,fleqn]{memoir}
\usepackage{titletoc}
\setcounter{tocdepth}{0}
\usepackage[compact,toctitles]{titlesec}
\titleformat{\chapter}[block]
{\huge}{\chaptertitlename\ \thechapter:\ }{0pt}{\huge}[\addtocounter{cherrychapter}{1}]
\title{H\&R}
%%% COUNTERS
\newcounter{cherrychapter}%[chapte]
\setcounter{cherrychapter}{0}
\newcommand\keyword[1]{%
\noindent%
{#1}%
\phantomsection% comment out if hyperref is noy used
\thecherrychapter\thechapter\addcontentsline{key-\thecherrychapter}{figure}{#1}
}
\makeatletter
\newcommand\listkeywordsname{KEYWORDS}
\newcommand\listofkeywords{%
\thecherrychapter\thechapter
\section*{\listkeywordsname}\@starttoc{key-\thecherrychapter}
\thecherrychapter\thechapter}
\makeatother
\begin{document}%BEGIN
\maketitle
\tableofcontents*
\part{A}
\chapter{aa}
\listofkeywords
\keyword{bb}
\section{aaa}
\keyword{bbb}
\subsection{aaaa}
\keyword{bbbb}
\chapter{cc}
\listofkeywords
\keyword{dd}
\section{ccc}
\keyword{ddd}
\subsection{cccc}
\keyword{dddd}
\end{document}

Thank you for aid. Best regards.

Answer 1

The costepping of cherrychapter can be done with xassoccnt, provided, this auxiliary counter is needed at all.

The main issue is that memoir does a redefinition of \@starttoc. One possible solution is to store the original LaTeX core definition to \@starttocorig before \documentclass and use that version instead of \@starttoc.

For more than one chapter it will report any number but the last one to be not existing. This looks like an expansion issue, actually, since memoir's version of \@starttoc tries to write to generate the file handle at the end of the document and opens the relevant file then, so #1 expands to the wrong chapter number.

\makeatletter
\let\@starttocorig\@starttoc
\makeatother

\documentclass[oneside,11pt,fleqn]{memoir}

\providecommand{\phantomsection}{}
\usepackage{morewrites}
\usepackage{xassoccnt}
\newcounter{cherrychapter}
\DeclareAssociatedCounters{chapter}{cherrychapter}

\usepackage{titletoc}
\setcounter{tocdepth}{0}
\usepackage[compact,toctitles]{titlesec}
\titleformat{\chapter}[block]
{\huge}{\chaptertitlename\ \thechapter:\ }{0pt}{\huge}%
\title{H\&R}
\newcommand\keyword[1]{%
  \noindent%
  {#1}%
  \phantomsection% comment out if hyperref is not used
  \addcontentsline{key-\thecherrychapter}{figure}{#1}
}
\makeatletter
\newcommand{\listofkeywordsbasic}{%
  \@starttocorig{key-\thecherrychapter}
}
\makeatother
\newcommand\listkeywordsname{KEYWORDS}
\newcommand\listofkeywords{%
  \section*{\listkeywordsname}\listofkeywordsbasic
}



\begin{document}%BEGIN
\maketitle
\tableofcontents*
\part{A}
\chapter{aa}
\listofkeywords
\keyword{bb}
\section{aaa}
\keyword{bbb}
\subsection{aaaa}
\keyword{bbbb}
\chapter{cc}
\listofkeywords
\keyword{dd}
\section{ccc}
\keyword{ddd}
\subsection{cccc}
\keyword{dddd}
\end{document}

Answer 2

As explained the internal command \@starttoc is redefined by memoir. The redefinition of the command \@starttoc is used to define the user command \newlistof.

To use the possibilities of \newlistof you can do the following:

\documentclass[oneside,11pt,fleqn]{memoir}

\providecommand{\phantomsection}{}

\usepackage{xassoccnt}
\newcounter{cherrychapter}
\DeclareAssociatedCounters{chapter}{cherrychapter}

\newcommand\keyword[1]{#1\phantomsection\addcontentsline{key-\thecherrychapter}{figure}{#1}}

\providecommand\listofkeywords{}
\newcommand\listkeywordsname{KEYWORDS}
\renewcommand\memendofchapterhook{
  \edef\x{\noexpand\newlistof{listofkeywords}{key-\thecherrychapter}{\listkeywordsname}}\x%
}


\begin{document}%BEGIN
\chapter{aa}
\listofkeywords

\keyword{bb}
\section{aaa}
\keyword{bbb}
\subsection{aaaa}
\keyword{bbbb}

\chapter{cc}
\listofkeywords

\keyword{dd}
\section{ccc}
\keyword{ddd}
\subsection{cccc}
\keyword{dddd}

\chapter{dd}
\listofkeywords

\keyword{ee}
\section{eee}
\keyword{eee}
\subsection{eeee}
\keyword{eeeee}
\end{document}
