\begin{abstract}
  The \etoc package gives to the user complete control on
  how the entries of the table of contents should be
  constituted from the \emph{name}, \emph{number}, and
  \emph{page number} of each sectioning unit. This goes via
  the definition of \emph{line styles} for each sectioning
  level used in the document. The package provides its own
  custom line styles as an example, next to the standard
  formatting inherited from the \LaTeX{} document classes. But
  the idea is to give the means to the user to delegate the
  details to packages dealing with list making environments
  (such as |enumitem|). Regarding the \emph{global style},
  \etoc typesets by default tables of contents in a
  multi-column format, with either a standard heading, or a
  ruled title, optionally with a frame around the table of
  contents. The \csa{tableofcontents} command can be used
  arbitrarily many times in the same document, and comes with
  a starred variant which gives local table of contents.

\section{Overview}

Popular packages dealing with TOCs include |tocloft|,
|titletoc| and |minitoc|. Why another one? well, I started
\etoc for my own use, and only later found out about the above
mentioned packages . . . I realize (to some extent, as I still
haven't read closely the documentations) that most if not all
of the \etoc functionality could well be already available in
the above mentioned packages.

\subsection{Initial motivation}

The specific initial impetus was to transform the `flat' data
contained in the |.toc| file into a nested structure which
could be given to list making environments.\footnote{I got
  started about this through reading this question on the
  \TeX{} Stackexchange site:\\ 
\href{http://tex.stackexchange.com/questions/79682/can-i-get-a-list-of-all-sections-as-a-simple-enumerate-list}{tex.stackexchange.com/questions/79682}}
For example, typesetting
the line corresponding to the first sub-section in a given
section would open a group which would be closed only when a
section, chapter, or part line entry in the |.toc| file would
be encountered. Package \etoc allows to do this very easily
and the opening and closing of the groups can be for example
|\begin{enumerate}| and |\end{enumerate}| pairs, will all the
customizing allowed by packages such as |enumitem|. 

Although there is a limitation to this method (the |.toc| file
may contain other commands, such as language changing
commands, which do not expect to see their scope limited in
this way inside a group), I believe this procedure will be
found the most convenient in many cases. However the own
package custom line styles (illustrated by the main table of
contents in this document) do not make use of environments to
avoid that problem.

\subsection{Line styles}

To implement the above idea, the command \csb{etocsetstyle}
will inform \etoc of what it should do at each sectioning
level, from |part| down to |subparagraph|. Other sectioning
names can be used too, if present in the document.

\subsubsection{\csb{etocetoclines} vs \csb{etocstandardlines}}

The \csb{etocetoclines} command selects the package predefined
line styles, and \csb{etocstandardlines} uses the standard
default formatting from the |article|, |book|, |report|, or
also |scrartcl| classes. For any document class proceeding in
a manner compatible to the |article| class in its
typesetting of the table of contents, the
\csb{etocstandardlines} should be functional: indeed nothing
is hard-coded into the package code; rather, when
\csb{etocstandardlines} is issued by the user, the package
cancels its own mechanism and gives back the leadership to the
class layer. Note though that this means that \etoc does not
provide utilities to change this or that length from the
\LaTeX{} default formatting of TOC entries. But if some other
package has done it, then this should work correctly also when
\etoc is in use (for its other aspects as will be described below).

\subsubsection{Instructing \etoc about sectioning command names}

If the document class uses other names, such as \emph{atom},
or \emph{particle}, the command \csb{etocsetlevel} will
instruct \etoc about it.

\subsection{Global style: multiple columns, ruled heading, framed table of contents}

At the global level, the default of \etoc is to typeset the
TOC on two columns, using the package |multicol|.
Additionally, the heading can be formatted as in the default
manner, or as a ruled heading, or the entire TOC can be
encapsulated in a frame (if it fits on the current page). And
the user can specify to use a single column output, or three
columns, etc . . .

\subsection{Local tables of contents}

With \etoc, the \csb{tableofcontents} command can be used
arbitrarily many times and it has a starred variant \tocstarb
which will print a local table of contents: i.e. all subsections
etc . . . inside a given section, or all subsubsections and
lower inside a given subsection, etc . . . 

\subsection{Displaying tables of contents defined
  elsewhere in the document}

A \LaTeX{} counter is associated with the successive tables of
contents. To set a reference point (which will become an
anchor if package |hyperref| is loaded) one just uses the
\cs{label} command as usual.
For example:\\
\hbox to \linewidth{\hss
  \tocstarb\space\csbi{label}\csbi{\string{my\_nice\_toc\string}}\hss}

Then, elsewhere in the document, doing:\\
\hbox to \linewidth{\hss \tocb\space\csbi{ref\string{my\_nice\_toc\string}}\hss}
will display again the same contents. However, the line styles
and global style (including the title) will be the current one and the
current value of the |tocdepth| counter is obeyed. As an example here is
the table of contents of Part \ref{part:custom}:


\begingroup
\etocstandardlines
\renewcommand{\etoctoprule}{\hrule height 0pt}
\etocruled[1]{\framebox[\linewidth]{\etocfontminusone I am from
    \hyperref[toc:c]{far away}}}
\label{toc:d}
\ref{toc:c}
\endgroup

We actually did something like:\\
\hbox to \linewidth{\hss
  \toc\space\cs{label}|{toc:1}|\cs{ref}|{toc:2}|\hss} Hence
\hyperref[toc:d]{\color{green!50!blue!50}the present location}
can itself now be referred to via |\ref{toc:1}|: this gives
the number of this TOC (\emph{i.e}
{\color{green!50!blue!50}\ref{toc:d}}) in the sequence of
document TOCs, will be a link if package |hyperref| is used,
and can be used elsewhere as \toc|\ref{toc:1}| (which is now 
equivalent to \toc|\ref{toc:2}|). 

For info, the \hyperref[toc:c]{\color{green!50!blue!50}distant toc}
is the one which has number {\color{green!50!blue!50}\ref{toc:c}}... 

The \cs{label} command should come before the reference via
\cs{ref} to the other TOC. A \cs{label} detected by \etoc
immediately (skipping spaces) after the command \toc will be
activated immediately after the update to the toc counter. A
\cs{label} after the \cs{ref} will not be treated by \etoc
itself and will refer to the latest reference point (possibly
to some counter updated in the title of the TOC or, although
this would require the user to have done a suitable set-up in the
line styles, even inside the TOC).

As another example let us now display a table of contents for
this first part of the document. Indeed, immediately after the
line in the source file starting with the first
\cs{part} we wrote:
\begin{verbatim}
\setcounter{tocdepth}{-2}
\tableofcontents* \label{toc:partone}
\setcounter{tocdepth}{3}
\end{verbatim}
The |tocdepth| being -2, nothing at
all was inserted in the page, but now that |tocdepth| has
been reset to 3, we can display the TOC with the simple
command:
\begin{verbatim}
\tableofcontents \ref{toc:partone}
\end{verbatim}
As explained above we could also add a label to refer to this
table of contents. The actual design is not pre-built in
\etoc: it combines the \etoc `framed' style (with a dummy
empty title, the actual title having been put inside the frame
as part of the \marg{start} code of the section `line
style'). The frame borders have been set to have the same
color as the one which serves as background for the entire
thing. This design (with other colors) is used also for
\hyperref[toc:clone]{\color{green!50!blue!50}this other toc} (the coding
used is reproduced there).

\section{The \csb{etocsetstyle} command}


\subsection{An example}

Let us explain how \etoc was used to produce the table of
contents displayed at the beginning of this second part (this
is a local table of contents, we used the command \tocstar).


We shall distinguish between the \emph{line styles} and the
\emph{global style}. First we describe how to set-up the
line styles. Essentially they were obtained in the following
manner%
\footnote{the present document has
  {\ttfamily\string\renewcommand\string{%
      \string\familydefault\string}\string{\string\sfdefault\string}}
  in its preamble, hence \csa{normalfont} switches to the
  |sans| typeface; so in the section line-style, I wrote
  \csa{rmfamily} instead.} \footnote{\etoc uses the |xspace|
  package, and there is no need to write
  \csa{etocname\string{\string} text} rather than just
  \csa{etocname text} for example. However, this forced us to
  add the mysterious \csa{unskip} before the dot in the
  subsubsection style.}

\begingroup\small
\begin{verbatim}
\etocsetstyle{section}
{\begin{enumerate}}
{\normalsize\bfseries\rmfamily\item}
{\etocname (page \etocpage)}
{\end{enumerate}}

\etocsetstyle{subsection}
{\begin{enumerate}}
{\normalfont\item}
{\etocname (p.~\etocpage)}
{\end{enumerate}}

\etocsetstyle{subsubsection}
{\par\nobreak\begingroup\normalfont
        \footnotesize\itshape\etocskipfirstprefix}
{\allowbreak\,--\,}
{\etocname}
{\unskip.\hfil\par\endgroup\pagebreak[3]}
\end{verbatim}
\endgroup

Each \csb{etocsetstyle} command has five mandatory arguments:\\
\hbox to \linewidth
{\hfil\csa{etocsetstyle}\color{blue}\marg{levelname}%
  \marg{start}\marg{prefix}\marg{contents}\marg{finish}\hfil}
The initially recognized \marg{levelname}'s are the sectioning
levels of the standard document classes (from \emph{part}
down to \emph{subparagraph}). 

The \marg{start} code is executed when a toc entry of that level is
encountered and the previous one was at a higher level. The
\marg{finish} code is executed when one again encounters a higher
level toc entry. In the mean-time all entries for that level are
typeset by executing first the \marg{prefix} code and then the
\marg{contents} code. 

\subsubsection{\csb{etocname} and \csb{etocpage}}

The line styles specifications use the commands \csb{etocname}
and \csb{etocpage} as synonyms for the name, respectively the
page number of the current entry. Temporarily, we relied on
the automatic numbering of the |enumerate| environments but
there is also a command \csb{etocnumber} to get the real thing
from the |.toc| file.


\subsubsection{The \csb{etocskipfirstprefix} command}

The chosen |subsubsection| style specifies to list the names of
the subsubsections from a given subsection in an in-line
manner, with -- as a separator. The command
\csb{etocskipfirstprefix}, which, if present, \emph{must} be
the very last one in the \emph{start} code, instructs to not
use that separator of the first item. 

With this style, one would have 
to be imaginative to design something then for paragraph and
subparagraph entries! perhaps as superscripts? Well, usually
one does not need paragraphs and subparagraphs numbered and
listed in the TOC, so our putative user here chose a design
where no provision is made for them and added the definitive:
\begin{verbatim}
\etocsetstyle{paragraph}{}{}{}{}
\etocsetstyle{subparagraph}{}{}{}{}
\end{verbatim}
This is also the situation with the default package line styles!

\subsubsection{secnumdepth and tocdepth}

The \LaTeX{} counter |secnumdepth|
decides (from part down to subparagraph) which levels are numbered and
automatically written to the |.toc| file. Its functioning
is completely independent from the \etoc package. The counter
|tocdepth| 
decides the finest level displayed in the table of contents: it
is obeyed by \etoc, and as \toc can now be used arbitrarily
times, this is an important customization lever.


\subsection{The \csb{etocsetlevel} command}

If your document uses other sectioning names, such as, for
example \emph{molecule}, or \emph{atom}, it should inform \etoc of
this in the following way:
\begin{verbatim}
\etocsetlevel{cell}{0}
\etocsetlevel{molecule}{1}
\etocsetlevel{atom}{2}
\etocsetlevel{nucleus}{3}
\end{verbatim}
The accepted numbers range from -1 to 5 inclusive. The package code
does:
\begin{verbatim}
\etocsetlevel{part}{-1}
\etocsetlevel{chapter}{0}
\etocsetlevel{section}{1}
\etocsetlevel{subsection}{2}
\etocsetlevel{subsubsection}{3}
\etocsetlevel{paragraph}{4}
\etocsetlevel{subparagraph}{5}
\end{verbatim}

\subsection{Further informations and let's make this a very long title to see how it will look like}


\subsubsection{The \csb{etocnumber} command}
So far, our specifications would use the numbering generated
by the |enumerate| environments, but it would be nicer to use
the actual numbers as found in the |.toc| file. This is
available via the \csb{etocnumber} command. To get the labels
in the |enumerate| list to use it we can proceed with the
syntax {\ttfamily label=\char32} from the package |enumitem|:
\begin{verbatim}
\etocsetstyle{section}
{\begin{enumerate}[label=\etocnumber]}
{\normalsize\bfseries\rmfamily\item}
{\etocname (page \etocpage)}
{\end{enumerate}}
\end{verbatim}
Rather than just\csa{etocnumber} we then used something like
|\fbox{\etocnumber}|.


\subsubsection{The \csb{etocifnumbered} switch}

The \csa{fbox} would give an unaesthetic result in the case of an unnumbered
section (which ended up in the table of contents via an \csa{addcontentsline}
command). The \csa{etocifnumbered}\marg{A}\marg{B} command executes \meta{A} if
the number exists, and \meta{B} if not. So our final code could be:
\begin{verbatim}
\etocsetstyle{section}
{\begin{enumerate}[label=\etocifnumbered{\etocnumber}{}]}
{\normalsize\bfseries\rmfamily\item}
{\etocname (page \etocpage)}
{\end{enumerate}}
\end{verbatim}
We used, actually:
\begin{verbatim}
\etocsetstyle{section}
{\begin{enumerate}[leftmargin=0pt,label=]}
{\normalsize\bfseries\rmfamily\item}
{\etocifnumbered{\makebox[1cm][c]{\color{green}\fboxrule1pt
       \fbox{\protect\normalcolor\etocnumber}}{\hspace{1cm}}
\etocname (page \etocpage)}
{\end{enumerate}}

\etocsetstyle{subsection}
{\begin{enumerate}[label=\etocnumber, leftmargin=1cm]}
{\normalfont \item}
{\etocname (p.~\etocpage)}
{\end{enumerate}}
\end{verbatim}

If we had changed only the |section| level, and not the
|subsection| level, an error on compilation would have occurred
because the package style for subsections expects to start `in
vertical mode'. An additional \csa{par} token in the
\meta{contents} part of the |section| level would fixed
this: |{...(page \etocpage)\par}|.


\subsection{The \csb{etocfontxxx...} commands}

The package predefines for use in its default line styles:
\begin{verbatim}
\newcommand\etocfontminusone{\normalfont \large \bfseries}
\newcommand\etocfontzero{\normalfont \normalsize \bfseries}
\newcommand\etocfontone{\normalfont \normalsize \bfseries}
\newcommand\etocfonttwo{\normalfont \normalsize}
\newcommand\etocfontthree{\normalfont \footnotesize}
\newcommand\etocfontfour{\normalfont \footnotesize}
\newcommand\etocfontfive{\normalfont \footnotesize}
\end{verbatim}
This only impact the package default line styles and does
nothing under the \csa{etocstandardlines} regime.
And, let us recall, levels four (paragraph) and five
(subparagraphs) are not displayed by the package
default line styles.



\color{red!50}
\addtocontents{toc}{\string\color{red!50}}

\subsubsection{This is a red subsubsection for illustrative purposes}

Just before this subsubsection we inserted in the |.tex| file:
\begin{verbatim}
\color{red}
\addtocontents{toc}{\string\color{red!50}}
\end{verbatim}
This entire subsubsection and its title is printed in red, as
well as the title of the next section (we cancel the color
change only after it). But what about its entry in the table
of contents? well it is red in the main table of contents at
the beginning of this document, which uses the package line
styles, and it is not red in the table of contents at the
beginning of this second document part. The reason is that the
\meta{finish} code for the subsubsection level closed a group,
whereas the \meta{start} and \meta{finish} code of the package
line styles do not contain group opening and closing
instructions. So here the group was closed while reading the
|.toc| file and this explains why the next entry in the local
TOC was not typeset in red.

In the present case the group at the subsubsection level is
there to confine the font changes, but this could be made
superfluous via adding a \csa{normalsize} to the
|subsection| specification. I take this opportunity to mention
that \etoc always typesets the entire table of contents inside
a group, hence no font change therein can propagate to the outside.


\section{Am I also in red?}

\begin{verbatim}
\normalcolor
\addtocontents{toc}{\string\normalcolor}
\end{verbatim}

\normalcolor
\addtocontents{toc}{\string\normalcolor}

Back to black. Note that this scope problem arises in real
life in a multi-lingual document, as the |babel| package
writes to the |.toc| file the language changes occurring in
the document. There is no easy general solution\footnote{one
  can insert by hand the language changes in each concerned
  sectioning command.} to this problem, which probably will
concern only a minority of cases. Again, the line styles
defined by \etoc do not use groups.

\section*{An unnumbered section}
\addcontentsline{toc}{section}{An unnumbered section}

I don't have much to say here. I just added an unnumbered
section, and made it appear in the |.toc| file.

\begin{verbatim}
\section*{An unnumbered section}
\addcontentsline{toc}{section}{An unnumbered section}
\end{verbatim}


\part{Package commands for global styles}


We shall illustrate the package functionalities through
comparing here various line styles: the standard formatting as
provided by the |article| class, the custom line styles we
defined above using enumerate environments, and the package
line styles.

\begin{verbatim}
\setcounter{secnumdepth}{4}
\setcounter{tocdepth}{4}
\end{verbatim}

\setcounter{secnumdepth}{4}
\setcounter{tocdepth}{4}

\etocruledstyle[2]{\normalfont\normalsize\rmfamily\itshape
 \fbox{\parbox{.8\linewidth}{This is the
      table of contents using enumerate environments for part,
      section and subsection, and an in-line italic style for
      subsubsections.}}}

First let us use again our set-up from the previous part. We add to it 
\begin{verbatim}
\etocsetstyle{part}
{\begin{enumerate}[label=\etocnumber,leftmargin=1em]}
{\etocfontminusone\item}
{\etocname}
{\end{enumerate}}
\end{verbatim}

\etocsetstyle{part}
{\begin{enumerate}[label=\etocnumber,leftmargin=1.5em]}
{\etocfontminusone\item}
{\etocname}
{\end{enumerate}}

\tableofcontents \label{toc:test}

Then we switch to the standard formatting of entries, as is
provided by the document class, but displayed here on two columns:
\begin{verbatim}
\etocstandardlines
\tableofcontents
\end{verbatim}

\etocstandardlines

\etocruledstyle[2]{%
\renewcommand{\etoctoprule}{\hrule height0pt}%
\normalfont\normalsize\rmfamily\itshape 
\parbox{.8\linewidth}{\centering 
This is the table of contents with standard
  entries (on 2 columns!).\\ Contrarily to
  \hyperref[toc:test]{\color{green!50!blue!50}the previous TOC} it
  displays the paragraph entries.}}

\tableofcontents

For the third example, we will use the starred variant
\tocstar to restrict its contents to this document part.
Furthermore we opt for a ``framed'' style, and specify some
colors (including a background color). We modify various
things from the package defaults. And we have also to cancel
this background color in the title (by default it applies both
to the title and to the contents).

\section{Specifying the global style}


The \emph{global} style says whether the TOC appears with
multiple columns or just one, whether the title is typeset as
in the |article| or |book| class, or should be centered above
the entries, with rules on its sides, or if the entire TOC
should be put in a frame. For example, to opt for a ruled
heading and single column layout, one issues commands of the
following type:
\begin{verbatim}
\etocruledstyle[1]{Title}
\tableofcontents (or \tableofcontents*)
or the shortcuts:
    \etocruled[1]{Title}  or  \etocruled*[1]{Title}
\end{verbatim}

\subsection{The command \csb{etocruledstyle}}

The general format of \csa{etocruledstyle} is:\\
\centerline{\color{blue}\csa{etocruledstyle}%
\oarg{number of columns}\marg{title of the toc}}
\noindent Note that the title is horizontal material, if it does not fit on one
line it can be put in a \csa{parbox} of a given width. We did this and even
enclosed the parboxes in \csa{fbox}es to get frames around them. For the example
with the standard formatting we did not use an \csa{fbox} and got rid of the
horizontal rules via:
\begin{verbatim}
\renewcommand{\etoctoprule}{\hrule height 0pt}
\end{verbatim}
The green frame for the table of contents heading at the start of the second
part of this document was obtained with
\begin{verbatim}
\etocruledstyle[1]{\etocfontminusone\color{green}
     \fboxrule1pt\fboxsep1ex
     \framebox[\linewidth]
              {\normalcolor\hfil Contents of this second part\hfil}}
\end{verbatim}


\subsection{The command \csb{etocmulticolstyle}}

This is also a command with one optional and one mandatory argument:\\
\centerline{\color{blue}\csa{etocmulticolstyle}\oarg{number\_of\_columns}\marg{heading}}
The \oarg{number\_of\_columns} can go from 1 to 10 (it defaults to 2, and from 2
on is passed to a |multicols| environment). The \marg{heading} can be something like:
\begin{center}
  {\ttfamily\string\chapter\lowast}\marg{title},\\ 
 or\\
\csa{etocstandardheading}\marg{title},\\
or\\
 \csa{etocstandardheadingnomarks}\marg{title}.
\end{center}
These last two commands do either \starit{section} or
\starit{chapter} depending on the document class, and the
first one puts the marks for the page headings. To emulate the
standard formatting one can thus use:\\
\centerline{\ttfamily\string\etocmulticolstyle[1]\string{%
\string\etocstandardheading\string{\string\contentsname\string}\string}}
After such a command, future \csa{tableofcontents} will use the
specified style. A shortcut for just one table of contents and
not affecting the styles of later TOCs is:\\
\centerline{\csa{etocmulticol}\oarg{number\_of\_columns}\marg{heading}}
And the starred form will be
\starit{etocmulticol}\oarg{number\_of\_columns}\marg{heading}.

\subsubsection{A point of some importance}

There is an important difference between the
\csa{etocmulticolstyle} and \csa{etocruledstyle} commands. The
mandatory argument of the former can not be just some
\emph{naked text}. It should rather be something like
|\hbox{naked text}| or |\vbox{naked text}|. 
%
More conveniently, one can use things such as:\\
\hbox to \linewidth{\hss |\section*{some not so naked text}|\hss} 
Else, you will get an error:\\
\hbox to \linewidth{\hss 
|ERROR: LaTeX Error: Something's wrong--perhaps a missing \item.|\hss}
In the special case where the command was
also given the optional argument |[1]|,
it is possible to feed it with `|naked text\par|'.


On the other hand, it is exactly the \emph{opposite} for
\csa{etocruledstyle} which expects things which fit inside a
horizontal box, hence it will gladly accepts a \emph{naked
  text} as argument, but will choke on things such as \cs{par}.


\paragraph{Do we really want paragraph entries in the TOC?}

\paragraph{really?}

\subsection{The command  \csb{etocruledstyle} (cont.)}


As a shortcut to set the style with this command and then make a
\csa{tableofcontents} or \tocstar call (in a group, so that the
style for future table of contents is not affected) we have: \\
\centerline{\csb{etocruled}\oarg{number\_of\_columns}\marg{title}}
And the starred form will be with \staritb{etocruled}.

\subsection{The command \csb{etocframedstyle}}

Same mechanism:\\
\centerline{\color{blue}\csa{etocframedstyle}\oarg{number\_of\_columns}\marg{title}}
and the accompanying shortcut:\\
\centerline{\csb{etocframed}\oarg{number\_of\_columns}\marg{title}}
Here the entire table of contents is framed, hence this can only work if it fits
on a page. Again the starred variant starts with \staritb{etocframed}.

\subsection{The command \csb{etocsettocstyle}}

This is a command with two mandatory arguments:\\
\centerline{\color{blue}\csa{etocsettocstyle}\marg{before\_toc}\marg{after\_toc}}
The \marg{before\_toc} part is responsible for typesetting the
heading, for example it can be something like
\starit{section}|{\contentsname}|. It can also contain
instructions to mark the page headings.\footnote{\etoc
  provides the command \csa{etocmarkboth}\oarg{optional\_name}, with an
  optional argument which defaults to \csa{contentsname}.} Or
it could check (book class) to see if two-column mode is on,
and switch to one-column style, and the \meta{after\_toc} part
would then reenact the two-column mode.\footnote{In our
  testing, we had some difficulties, when using the |multicol|
  package in a book class document with the two-column global
  option. So, as we use |multicol| by default we decided
  against trying to automatize a check for such a possible
  |twocolumn| class option. It is up to the user to decide (or
  not) to switch back and forth from two-column to one-column
  when typesetting table of contents.}

The three commands \csa{etocmulticolstyle}, \csa{etocruledstyle}, and
\csa{etocframedstyle} actually call \csa{etocsettocstyle} as a
lower-level routine.

\section{Summary of the main  local and global style
  commands}

\subsection{Setting up local styles}

\hbox{\color{green}\fboxrule1pt\fboxsep1em
\setbox0\hbox{\csa{etocname}, \csa{etocnumber}, \csa{etocpage},

\csa{etocsettocstyle}\marg{before\_toc}\marg{after\_toc}}}}

\subsection{Displaying Tables of Contents}


\medskip \hbox{\color{green}\fboxrule1pt\fboxsep1em
  \setbox0\hbox{\csa{etocname}, \csa{etocnumber},
    \csa{etocpage}, \csa{etocifnumbered}\marg{A}\marg{B}}%
  \framebox[\linewidth][c]

      \csa{etocruled}\oarg{number\_of\_columns}\marg{title}\\
      \csa{etocruled}\lowast\oarg{number\_of\_columns}\marg{title}\\
      \csa{etocframed}\oarg{number\_of\_columns}\marg{title}\\
      \csa{etocframed}\lowast\oarg{number\_of\_columns}\marg{title}%
   }}}

\subsection{Labels and references}

The commands to actually display the table of contents
can be followed with optional labels or references:\par

\medskip \hbox{\color{green}\fboxrule1pt\fboxsep1em
  \setbox0\hbox{\csa{etocname}, \csa{etocnumber},
    \csa{etocpage}, \csa{etocifnumbered}\marg{A}\marg{B}}%
  \framebox[\linewidth][c]
  {\vbox{\hsize\wd0\normalcolor\noindent
      \toc\\
      \toc \cs{label}|\{toc:here\}|\\ 
      \toc \cs{ref}|\{toc:far\}| \\
      \toc \cs{label}|\{toc:here\}| \cs{ref}|\{toc:far\}| \\
      \tocstar\\
      \tocstar \cs{label}|\{toc:here\}| 
   }}}


\medskip The starred form displaying a local table of
contents, it will not react to a \cs{ref} following it. When
re-displaying another toc, only its contents are transferred:
both the line styles and the global style are the ones
currently defined, not the ones from the cloned toc.

The shortcuts for setting up and using in one go the multicol,
ruled, and framed global styles can be followed in the
similar manner by a label and/or a reference.


% The command \csb{etocref} when given a label |toc:x| as
% argument produces the number of the corresponding TOC:
% \emph{i.e.} 1 for the first in the document etc... this is the
% same information as in \cs{ref}|{toc:x}| or \cs{ref*}|{toc:x}|
% but without any hyperlink or other extraneous data. It is
% mainly used internally by \etoc, but can be used as a perhaps
% more robust command than \cs{ref} or \cs{ref*} when 
% typesetting the number of the TOC.

\subsection{Example of a cloned local TOC}


We try out |\tableofcontents \ref{toc:b}|. 
First we have to specify the design. 
I got  motivated by a
question\footnote{\href{http://tex.stackexchange.com/questions/83184/how-to-change-style-and-color-of-table-of-content}{tex.stackexchange.com/questions/83184}}
I saw on the \TeX{} StackExchange site. I copied the color RGB
specifications from an answer which had been provided to the
question. The \cs{etocframedstyle} puts the title
on the top rule in a centered position. This is not very
convenient for this example so we included the title as part of the
\meta{start} code at section level, to get it \emph{inside}
the frame.

The coding is a bit involved as it does not use any additional
package. The framed style allowed us to specify a background
color. Generally speaking all color commands inside \etoc are
initially defined to do nothing, so the choice to use or not
color packages is left to the user.



\part{Customizing \etoc}

      subsections in this part. It carries the label |toc:c|}}} 

\tableofcontents* \label{toc:c}


\section{Customizing  the \etoc line styles}


We will simply list the relevant commands as defined in the package. Customizing
them goes through suitable \csa{renewcommand}s:

\begin{verbatim}
\newcommand\etocfontminusone{\normalfont \large \bfseries}
\newcommand\etocfontzero{\normalfont \normalsize \bfseries}
\newcommand\etocfontone{\normalfont \normalsize \bfseries}
\newcommand\etocfonttwo{\normalfont \normalsize}
\newcommand\etocfontthree{\normalfont \footnotesize}
\newcommand\etocfontfour{\normalfont \footnotesize}
\newcommand\etocfontfive{\normalfont \footnotesize}

\newcommand\etocsepminusone{4ex plus .5ex minus .5ex}
\newcommand\etocsepzero{2.5ex plus .4ex minus .4ex}
\newcommand\etocsepone{1.5ex plus .3ex minus .3ex}
\newcommand\etocseptwo{1ex plus .15ex minus .15ex}
\newcommand\etocsepthree{.25ex plus .05ex minus .05ex}
\newcommand\etocminusonelrmargins{1em}

\newcommand\etocbaselinespreadminusone{1}
\newcommand\etocbaselinespreadzero{1}
\newcommand\etocbaselinespreadone{1}
\newcommand\etocbaselinespreadtwo{1}
\newcommand\etocbaselinespreadthree{.9}

\newcommand\etoctoclineleaders
{\hbox{\normalfont\normalsize\hbox to 2ex {\hss.\hss}}}

\newcommand\etocabbrevpagename{p.~}
\end{verbatim}

No customizing of the standard line styles is possible from
within \etoc. As already explained, when
\csa{etocstandardlines} has been issued, the package just makes
itself very discrete and acts only at the global level, and
the TOC entries are (hopefully) formatted as would have
happened in the absence of \etoc. In this mode the
\csa{etocsetstyle} commands will have an effect only after the
document encounters again an \csa{etocetoclines} command.

The \csa{etocstandardlines} mechanism will work also with
sectioning commands made known to \etoc via \csa{etocsetlevel},
under the condition of course that these sectioning commands
are accompanied with all the relevant definitions for
typesetting toc entries in the \LaTeX{} default manner
(existence of the macros \csa{l@something} . . .).

\section{Customizing the global styles}


Again we list the relevant macros, what they do should be legible from their
names:
\begin{verbatim}
\newcommand\etocabovetocskip{3.5ex plus 1ex minus .2ex} 
\newcommand\etocbelowtocskip{3.5ex plus 1ex minus .2ex}

\newcommand\etoccolumnsep{2em}
\newcommand\etocmulticolsep{0ex}
\newcommand\etocmulticolpretolerance{-1}
\newcommand\etocmulticoltolerance{200}

\newcommand\etocinnertopsep{2ex}

This last command is a hook, it is positioned immediately
after the beginning of a minipage environment where the
contents of the framed TOC are typeset. 

Regarding the dimensions of the top rule they can be specified
in |ex|'s or |em|'s as for example:\\
\hbox to \linewidth{\hss 
|\renewcommand{\etoctoprule}{\hrule height 1ex}|\hss} 
The package code is done in such a manner
that it is the font size in instance at the end of typesetting
the title argument to \csa{etocruledtoc} or
\csa{etocframedtoc} which will be used for the meaning of the
`1ex'. Of course also the other rule commands can have their
dimensions in font relative units, but their values are
decided on the basis of the font in effect just before the
table of contents.

The top and bottom rules do not have to be rules and can be
horizontal \emph{leaders} (of a specified height) in the general
\TeX{} sense. However the left and right rules are not
used as (horizontal) leaders but as objects of a given specified
width. Note that \emph{only} the Plain \TeX{} syntax for rules is
accepted here.

\etocsetstyle{subsection}{\begin{enumerate}[itemsep=0pt,%

{\roman{enumi}. \normalfont\etocname (\etocnumber, p.~\etocpage)}
{\end{enumerate}}
\renewcommand{\etoccolumnsep}{2.75em}
\renewcommand{\columnseprule}{1pt}
\etocmulticol[3]{\subsection{All subsections of this document}}
\end{verbatim}

\setcounter{tocdepth}{2}

\begingroup

\subsection{Compatibility with other packages}

\etoc uses the packages |multicol| and |xspace|. It is
|hyperref| aware and hopefully |hyperref| compatible! 

The
macros \csa{etocname}, \csa{etocnumber}, and \csa{etocpage}
contain the |hyperref| links, if present (note that the
|linktoc=all| option of |hyperref| tells it to put a link also
in the page number corresponding to a given toc entry). The
table of contents of the present document are fully linked.

\etoc has not been tested with other packages than those
cited. It has been tested to work as expected with the
|article|, |book| and |scrartcl| document classes.



\subsection{\TeX nical matters}

The \csa{etocname}, \csa{etocnumber}, \csa{etocpage} and
\csa{etocifnumbered} macros are protected against premature
expansion. The macro \csa{etocsetstyle}, as well as
\csa{etocsetlevel} and the global style commands
\csa{etocmulticolstyle}, \csa{etocruledstyle} and
\csa{etocframedstyle} obey \LaTeX{}'s groups.


\subsection{Errors and catastrophes}

After adding TOCs here and there, with plenty of labels and
references, perhaps the \LaTeX{} compilation will complain.
Try running once more to see what happens, the problem could
go away. In certain extreme cases (\emph{e.g.}, removing the
use of package |hyperref| from the document), one must trash
the previous |.aux| and |.toc| files. And as usual with toc
and labels, after each change, one has to run latex a
certain number of times to let the produced document get its
final appearance.


\part{The code}


This source file |etoc.dtx| outputs \emph{directly and
  systematically} the package file |etoc.sty| when one does
|latex etoc.dtx| or |pdflatex etoc.dtx| (an |etoc.ins| file is
also produced, for distributions expecting it for
installation). Two more runs are necessary to finish producing
the documentation. The |etoc.sty| file should be moved to a
suitable location within the \TeX{} distribution.
