\begin{abstract}
  Provides |\toftagstart{}|, |\toftagstop{}|, |\toftagthis{}|,
  |\tofuntagthis{}| to tag chapters, sections or any other sectioning units
  destined to end up in the table(s) of contents. Then each one of
\begin{verbatim}
  \tableof{required tags}
  or \tablenotof{excluded tags}
  or \tableoftaggedcontents{required tags}{excluded tags}
\end{verbatim}
  typesets a table of contents (with no heading) obeying the conditions. These
  macros can each be used multiple times in the document with varying
  arguments.

  If the document contains no usage of |\tableofcontents|, the preamble should
  also contain an additional |\AtBeginDocument{\tofOpenTocFileForWrite}|.

  The main |\tableofcontents| can also be influenced by tags like this:
\begin{verbatim}
  \nexttocwithtags{required tags}{excluded tags}
  \tableofcontents
\end{verbatim}

  Depending on the document class and packages, |\tableofcontents| however may
  be usable only once, contrarily to the |\tableof{}| et al.\@ package macros.

\end{abstract}

\section{Tagging commands}

\subsection{\csbhyp{toftagstart \{tag1, tag2, ...\}} and
  \csbhyp{toftagstop \{tag1, tag2, ...\}}}

These commands have a mandatory argument which is a comma separated list of
tags. The tags need not have been predeclared.
\begin{verbatim}
\toftagstart{kitchenware, weaponry, gastronomy} 
\section{Dealing with knives}    % tagged with kitchenware+weaponry+gastronomy

\toftagstop{kitchenware}
\section{Hunting rabbits}        % tagged with weaponry+gastronomy

\toftagstart{tag1}
\subsection{This is tagged, too} % tagged with weaponry+gastronomy+tag1

\toftagstop{weaponry}
\section{Eating rabbits}         % tagged with gastronomy+tag1
\end{verbatim}

\subsection{\csbhyp{toftagthis \{tag1, tag2, ...\}}  and
  \csbhyp{tofuntagthis \{tag1, tag2, ...\}}}

The \csa{toftagthis} command flags with the comma separated values from its
list argument only the \emph{next} sectioning command. The effect is not
cumulative: it is the last use of \csa{toftagthis} which counts; use it for
all the needed tags at once.

The \csa{tofuntagthis} command similarly untags only the \emph{next} entry.
Similarly, only the tags in the last call of \csa{tofuntagthis} are taken into
account.
\begin{verbatim}
\toftagstart{kitchenware, rabbits}
\section{Knives and rabbits}     % tagged with kitchenware and rabbits

\tofuntagthis{kitchenware}
\subsection{Hunting rabbits}     % tagged only with rabbits

\subsection{Best knives for cooking} % tagged with kitchenware and rabbits

\toftagstart{ecology}
\toftagthis{climate}
\section{Knives and global climate} % tagged with kitchenware+rabbits+ecology+climate

\toftagstop{kitchenware}
\section{The rabbit in the wild}    % tagged with rabbits+ecology
\end{verbatim}

\subsection{Spaces}

Spaces in tags and around commas in tag lists are transparently removed.
Tags may be macros, they are completely
expanded before use.

\section{Table of contents commands}

\subsection{\csbhyp{nexttocwithtags \{required tag1, required tag2,
    ...\}\{excluded tag1, excluded tag2, ...\}}}

This command influences the next \csa{tableofcontents} (or equivalent) command:
\begin{verbatim}
\nexttocwithtags{A, B}{C, D, E}
\tableofcontents
\end{verbatim}
will let \csa{tableofcontents} print only the sectioning units having been
flagged with both |A| and |B| and none of |C|, |D|, or |E|.

\begin{framed}
  \noindent\textbf{DO NOT FORGET THE SECOND PAIR OF BRACES EVEN IF YOU ONLY
    WANT TO REQUIRE SOME TAGS:} \csa{nexttocwithtags}|{tag1, tag2}{}|.
\end{framed}

\subsubsection{starred variants}

There are starred variants:
\begin{verbatim}
\nexttocwithtags{A, B}{C, D, E}   % A and B and neither C nor D nor E
\nexttocwithtags*{A, B}{C, D, E}  % (A or B) and neither C nor D nor E
\nexttocwithtags{A, B}*{C, D, E}  % A and B and (not C or not D or not E)
\nexttocwithtags*{A, B}*{C, D, E} % (A or B) and (not C or not D or not E)
\end{verbatim}

\subsection{\csbhyp{tableoftaggedcontents \{required tag1, required tag2,
    ...\}\{excluded tag1, excluded tag2, ... \}}}

This command is provided in case the document class allows only a single use
of \csa{tableofcontents}, indeed \csa{tableoftaggedcontents} can be used
arbitrarily many times. \textbf{However it does not typeset a heading}. Example:
\begin{verbatim}
\section*{A table of tagged contents}  % <- needs to be explicitely added
\tableoftaggedcontents{weaponry, hunting}{ecology, climate}
\end{verbatim}
This will limit the printed TOC entries to the ones which have been tagged with
|weaponry| and also with |hunting|, but not with |ecology| and neither with
|climate|.

\subsubsection{starred variants}

There are starred variants:
\begin{verbatim}
\tableoftaggedcontents{A, B}{C, D, E}   % A and B and neither C nor D nor E
\tableoftaggedcontents*{A, B}{C, D, E}  % (A or B) and neither C nor D nor E
\tableoftaggedcontents{A, B}*{C, D, E}  % A and B and (not C or not D or not E)
\tableoftaggedcontents*{A, B}*{C, D, E} % (A or B) and (not C or not D or not E)
\end{verbatim}

\subsection{\csbhyp{tableof \{required tag1, required tag2, ...\}}}

This is equivalent to |\tableoftaggedcontents{required tag1, ...}{}|.
\begin{verbatim}
\tableof{weaponry,hunting}  % will print the entries tagged with weaponry 
                                                             AND hunting
\end{verbatim}
There is a starred variant:
\begin{verbatim}
\tableof*{weaponry, hunting} % will print the entries tagged with weaponry 
                                                              OR hunting
\end{verbatim}

\subsection{\csbhyp{tablenotof \{excluded tag1, excluded tag2, ...\}}}

This is equivalent to |\tableoftaggedcontents{}{excluded tag1, ...}|.
\begin{verbatim}
\tablenotof{weaponry, hunting}  
% will print the entries NOT tagged with weaponry NEITHER with hunting
\end{verbatim}
There is a starred variant:
\begin{verbatim}
\tablenotof*{weaponry, hunting} 
% will print the entries NOT tagged with weaponry OR NOT tagged with hunting
\end{verbatim}


\subsection{\csbhyp{tofOpenTocFileForWrite}}

The contents of the |.toc| file (if it already exists) are read into memory by
\tableof once, at the time of |\begin{document}|.\footnote{New with |1.3|.
    Earlier versions read the |.toc| file at the time of
    \csa{usepackage\{tableof\}}. But this could cause a problem if the |.toc|
    file used characters not yet activated by Babel.} 
Notice that this reading of the |.toc| file into memory is only of relevance
if the document makes use of one of the \csa{tableoftaggedcontents},
\csa{tableof} or \csa{tablenotof} commands.

The creation of the |.toc| file is \emph{not} dealt with by \tableof itself:
either this will be done by a standard \csa{tableofcontents} command somewhere
in the document, or, one may use the package provided command
\csa{tofOpenTocFileForWrite} which does not display anything and just does
what its name indicates. This command should \textbf{not} be used in the
preamble, however
\begin{verbatim}
    \usepackage{tableof}
    \AtBeginDocument{\tofOpenTocFileForWrite}
\end{verbatim}
is possible.

Please consider: this command should \emph{not} be used when the
  document makes use of its own \csa{tableofcontents} or equivalent. It is
  provided \emph{only} for the case where the document uses \emph{exclusively}
  \csa{tableoftaggedcontents}, \csa{tableof} and \csa{tablenotof}.

\section{Compatibility with other packages}

\tableof checks if |hyperref| is loaded as |hyperref| modifies the format of the
lines in the |.toc| file (and this must be taken into account). This check is
done at the \csa{begin}|{document}| so the order of loading is not important.

\tableof requires the document |.toc| file to use the |\contentsline| macro
(possibly patched by other packages). It is thus incompatible with the
|beamer| class. However, if |beamer| is used in an article mode, i.e., with
the article class in conjunction with the |beamerarticle| package, then \tableof
should work.

\tableof adds the tag data to the |.toc| file, but this data self-defines
itself to do nothing when not activated by \tableof's own commands. Since
release |1.3|, these redefinitions are done in \emph{one single} line of the
|.toc| file to circumvent interference of |biblatex| which adds
commands to the |.toc| line on every other line (thus, potentially right in
the middle of multi-line commands \verb+:-(+.)

No testing has actually been done of compatibility with packages manipulating
tables of contents, apart from
\etoc.\footnote{\url{http://www.ctan.org/pkg/etoc}} It went fine.

|2021/07/05 v1.4c:    |ensure the added scope-limiting group for |\tableof{}|
and alike macros encompasses all contents of the |.toc| file even in presence
of packages hacking into these contents (in particular |biblatex|).
%! https://tex.stackexchange.com/questions/603540/tableof-package-erases-citations/

|2018/10/02 v1.4b:    |fix for situations when a |\clearpage| before
the |\end{document}| resulted in the loss of the |\tof@finish| token from |.toc|
file, causing the package to misbehave.
%! (cf.
%! \url{https://tex.stackexchange.com/q/358014/4686}).
The package
|atveryend| is now required.\footnote{\url{http://www.ctan.org/pkg/atveryend}}

|2015/03/10 v1.4a: i. |changes in the code to make it more easily patchable by
other packages (I have especially the next release of \etoc in mind): changes
to the way |\tof@begin|, |\tof@finish| are set up, new |\tof@global| which
defaults to nothing but may be set to be |\global| (this is in view of doing
TOCs as tabulars of longtables, in the way \etoc |1.08| will permit).

|                 ii. |improved sectioning of the documentation.

|2015/02/20 v1.4:  i. |some code efficiency improvements (perhaps...).

|                 ii. |improved documentation.

|2015/02/11 v1.3:  i. |comma separated lists of tags now allow spaces.

|                 ii. |only one line used for the |.toc| code silently
unactivating |tableof| if its |\usepackage{tableof}| has been removed from the
document source. (needed due to aggressive |biblatex| interference with |.toc|
files.)

|                iii. |reading of .toc file is delayed to |\begin{document}| to
account for possible Babel active characters used therein. Not relevant if
document uses standard |\tableofcontents| or like commands.

|2013/03/04 v1.2:  i. |added \csa{tableoftaggedcontents} as a wrapper for using
\csa{nexttocwithtags} followed with |tableof|'s private copy of the |.toc| data.

|                ii.  |added \csa{if@filesw} test to \csa{tofOpenTocFileForWrite}.

|2012/12/13 v1.1: i.  |new command \csa{nexttocwithtags}.

|                ii.  ||.toc| may be input in another document not loading \tableof.

% |1.3| codes this |\tof@readtoc| slightly better (copied from \etoc.dtx).
%    \begin{macrocode}
\def\tof@readtoc {%
  \ifeof\tof@tf
  \else
     \read\tof@tf to \tof@buffer
     \tof@toctoks\expandafter\expandafter\expandafter
       {\expandafter\the\expandafter\tof@toctoks\tof@buffer}%
     \expandafter\tof@readtoc
  \fi }
%    \end{macrocode}
% |1.3| of |2015/02/11| moves the reading of the toc file to At Begin
% Document. This is needed for Babel activated characters. I also re-use
% |\endlinechar-1| which I had commented out since release |1.1|. Notice
% though that this is irrelevant if the document uses |tableof| only via its
% tagging abilities, and has standard |\tableofcontents| command to print the
% TOC.
%
% |1.4c| injects |\tof@begingroup| and |\tof@endgroup| to wrap the gathered
% the contents of the toc file, rather than having them arise from expansion
% of |\tof@begin| and respectively |\tof@finish|. This avoids a problem with
% |biblatex| additions to the |.toc| file happening before |\tof@begin|. They
% need to have their scope limited. The |\tableof{}| macro and variants will
% thus achieve this automatically via the |\tof@begingroup/\tof@endgroup| pair
% now explicitly added to |\tof@toctoks| contents.
%
% \etoc (a.t.t.o.w |1.09c 2020/05/15|) has some handling of
% |\tof@begingroup/\tof@endgroup| which as far as I understand can
% currently remain as it is. But there is something weird in \etoc with
% a test of |\tof@finish| which probably is in need of revision (even
% independently of changes here).
%
% These changes however mean for usage of |\nexttocwithtags| that whatever
% macro is used to typeset the TOC, it is now the one bearing the
% responsability for creating the scope-limiting group.
%    \begin{macrocode}
\AtBeginDocument{\IfFileExists{\jobname.toc}
    {{\endlinechar\m@ne
        \makeatletter
        \newread\tof@tf
        \openin\tof@tf\@filef@und
        \tof@toctoks{\tof@begingroup}%
        \tof@readtoc
        \global\tof@toctoks=\expandafter{\the\tof@toctoks\tof@endgroup}%
        \closein\tof@tf}}{}}
%    \end{macrocode}
% The trick is that |\@ifundefined| chooses the undefined branch if the
% meaning is |\relax|. Thus it is possible for \tableof to define and use
% |\tof@begin| and later set it to |\relax|, the entire influence of \tableof
% will then be turned off.
%
% |1.2| of |2013/03/04|: \csa{string\{}->\{, idem with
% \}. And added \csa{if@filesw} test.
%
% |1.3| of |2015/02/11|: to circumvent aggressive biblatex manipulation of the
% |.toc| file, I put things to the |.toc| file in one-go; else weird commands
% might get inserted right in the middle of arguments to a multi-line macro!
% also removed a bunch of |\string|'s: when I first wrote this package I had
% still limited understanding of \TeX's macros.
%
% |1.4a| uses |\@empty| for the default |\tof@finish| rather than |\relax|,
% for no special reason. Also the |\let|'s in case |\tof@begin| is undefined
% or |\relax| are all made global, because for compatibility with the fancy
% things \etoc |1.08| will allow for TOC as table we need a global mode, and
% the simplest is here to do the things global by default.
%
% |1.4c| replaces |{}| (last argument of |\@ifundefined|) by |\relax|. No
% strong reason. We and \etoc use |\endlinechar-1| anyhow.
%    \begin{macrocode}
\AtBeginDocument{
    \addtocontents{toc}{\string\@ifundefined{tof@begin}%
       {\global\let\string\tof@begin\relax
        \global\let\string\tof@finish\string\@empty
        \global\let\string\tof@starttags\string\@gobble
        \global\let\string\tof@stoptags\string\@gobble
        \global\let\string\tof@tagthis\string\@gobble
        \global\let\string\tof@untagthis\string\@gobble}\relax}
    \addtocontents{toc}{\string\tof@begin}
%    \end{macrocode}
% \LaTeX\ of 2020 or 2021 always has |\contentsline| with four arguments.
% So an update should be done here to always gobble four, else in absence
% of |hyperref| some |{}| are left. Does not seem to matter a lot except
% if all is executed in math mode... thanks to \etoc for example.
% No urgency here, only mentioning for the record.
%    \begin{macrocode}
    \@ifpackageloaded{hyperref}
       {\def\tof@gobblethree@orfour#1#2#3#4{}%
        \ifx\hyper@last\@undefined\tof@toctoks{}\fi}
       {\def\tof@gobblethree@orfour#1#2#3{}}}
%    \end{macrocode}
% |1.4b| (belatedly) fixes issue with |\tof@finish| getting lost due
% to a final |\clearpage| before |\end{document}|. Indeed, formerly
% code did:
%
% {\centering|\AtEndDocument{\addtocontents{toc}{\string\tof@finish}}|\par}
%
% But we can't replace this by some |\immediate\write\@auxout| at end
% document, because it would act \emph{before} the writes triggered by
% the |\clearpage| from inside |\end{document}|, if no such
% |\clearpage| ended the document body. Thus |\AfterLastShipout| comes
% to the rescue, from package |atveryend|.
%    \begin{macrocode}
\AfterLastShipout
    {\immediate\write\@auxout{\string\@writefile{toc}{\string\tof@finish}}}
%    \end{macrocode}
% |1.4a| makes the things more easily patchable by other packages, especially
% I have \etoc in mind.
%
% |\tof@@starttags| and |\tof@@stoptags| are defined a bit later in the code.
% And we use |\tof@global|. And we need |\tof@@finish| to reset |\tof@tags| to
% empty, just in case |\tof@global| was |\global|. And also |\contentsline| !!
% But here it is a problem redefining it globally. In normal use of \tableof,
% nothing needs to be done, because the |\tof@endgroup| closes the scope. In
% global mode (triggered only by \etoc with |\etocglobaldefs| for tabulars),
% it needed to globally modify |\contentsline|, thus it or \etoc has to
% globally unmodify it. \etoc |1.08| by itself without \tableof doesn't have
% to reset |\contentsline| because it re-defined it \emph{before} an eventual
% tabular. But as it forced \tableof to do global things, in such case \etoc
% will have to proceed globally as well.
