\BeginIndex{Package}{tocbasic}%
\BeginIndex{}{table of contents}%
\BeginIndex{}{list>of contents}%
\BeginIndex{}{file>extension}%
The main purpose of package \Package{tocbasic} is to provide features for
authors of classes and packages to create own tables or lists of contents like
the list of figures and the list of tables and thereby allow other classes or
packages some types of control over these. For examples package
\Package{tocbasic} delegates language control of all these tables and lists of
contents to package \Package{babel}\IndexPackage{babel}%^^A
\ (see \cite{package:babel})%^^A
. So automatic change of language will be provided inside
all these tables and lists of contents. Using \Package{tocbasic} will
exculpate authors of classes and packages from implementation of such
features.

\KOMAScript{} itself uses \Package{tocbasic} not only for the table of
contents but also for the already mentioned lists of figures and tables.

\section{Basic Commands}
\label{sec:tocbasic.basics}

Basic commands are used to handle a list of all extensions\textnote{file
  extension, table or list of contents} known for files representing a table
of contents or list of something.  Entries to such files are typically written
using \Macro{addtocontents}\important{\Macro{addtocontents},
  \Macro{addcontentsline}} or \Macro{addcontentsline}.  There are also
commands to do something for all known extensions.  And there are commands to
set or unset features of an extension or the file represented by the
extension.  Typically an extension also has an owner\textnote{file owner}.
This owner may be a class or package or a term decided by the author of the
class or package using \Package{tocbasic}, e.\,g., \KOMAScript{} uses the
owner \texttt{float} for list of figures and list of tables, and the file name
of the class file as owner for the table of contents.

\begin{Declaration}
  \Macro{ifattoclist}\Parameter{extension}\Parameter{true
    part}\Parameter{false part}
\end{Declaration}
\BeginIndex{Cmd}{ifattoclist}%
This command
may be used to ask, wether or not an \PName{extension} is already a known
extension.  If the \PName{extension} is already known the \PName{true
  instructions} will be used, otherwise the \PName{false instructions} will be
used.
\begin{Example}
  Maybe you want to know if the extension ``\File{foo}'' is already in use to
  report an error, if you can not use it:
\begin{lstcode}
  \ifattoclist{foo}{%
    \PackageError{bar}{%
      extension `foo' already in use%
    }{%
      Each extension may be used only
      once.\MessageBreak
      The class or another package already
      uses extension `foo'.\MessageBreak
      This error is fatal!\MessageBreak
      You should not continue!}%
  }{%
    \PackageInfo{bar}{using extension `foo'}%
  }
\end{lstcode}
\end{Example}
\EndIndex{Cmd}{ifattoclist}%

\begin{Declaration}
  \Macro{addtotoclist}\OParameter{owner}\Parameter{extension}
\end{Declaration}
\BeginIndex{Cmd}{addtotoclist}%
This command
adds the \PName{extension} to the list of known extensions. But if the
\PName{extension} is a known one already, then an error will be reported to
avoid double usage of the same \PName{extension}.

If the optional argument, \OParameter{owner}, was given this \PName{owner}
will be stored to be the owner of the \PName{extension}.  If the optional
argument has been omitted, \Package{tocbasic} tries to find out the file name
of the current processed class or package and stores this as owner.
This\textnote{Attention!} will fail if \Macro{addtotoclist} was not used,
loading a class or package but using a command of a class or package after
loading this class or package.  In this case the owner will be set to
``\PValue{.}''.

Please note\textnote{Attention!} that an empty \PName{owner} is not the same
like omitting the optional argument with the braces. An empty argument would
result in an empty owner.
\begin{Example}
  You want to add the extension ``\File{foo}'' to the list of known extension,
  while loading your package with file name ``\File{bar.sty}'':
\begin{lstcode}
  \addtotoclist{foo}
\end{lstcode}%
  This will add the extension ``\PValue{foo}'' with owner ``\PValue{bar.sty}''
  to the list of known extensions, if it was not already on the list of known
  extensions. If the class or another package already added the extension you
  will get the error:
\begin{lstoutput}
  Package tocbasic Error: file extension `foo' cannot be used twice

  See the tocbasic package documentation for explanation.
  Type  H <return>  for immediate help.
\end{lstoutput}
  and after typing \texttt{H} and pressing the return key you will get the
  help:
\begin{lstoutput}
  File extension `foo' is already used by a toc-file, while bar.sty
  tried to use it again for a toc-file.
  This may be either an incompatibility of packages, an error at a package,
  or a mistake by the user.
\end{lstoutput}

  Maybe your package has a command, that creates list of files dynamically.  In
  this case you should use the optional argument of \Macro{addtotoclist} to
  set the owner.
\begin{lstcode}
  \newcommand*{\createnewlistofsomething}[1]{%
    \addtotoclist[bar.sty]{#1}%
    % Do something more to make this list of something available
  }
\end{lstcode}
  If the user calls now, e.\,g.,
\begin{lstcode}
  \createnewlistofsomething{foo}
\end{lstcode}
  this would add the extension ``\PValue{foo}'' with the owner
  ``\PValue{bar.sty}'' to the list of known extension or report an error, if the
  extension is already in use.
\end{Example}
You may use any owner you want.  But it should be unique!  So, if you would
be, e.\,g., the author of package \Package{float} you could use for example
owner ``\PValue{float}'' instead of owner ``\PValue{float.sty}'', so the
\KOMAScript{} options for the list of figures and the list of tables will also
handle the lists of this package. Those are already added to the known
extensions when the option is used. This is because \KOMAScript{} already
registers file extension ``\PValue{lof}'' for the list of figures and file
extension ``\PValue{lot}'' for the list of tables with owner
``\PValue{float}'' and sets options for this owner.
\EndIndex{Cmd}{addtotoclist}%

\begin{Declaration}
  \Macro{AtAddToTocList}\OParameter{owner}\Parameter{instructions}
\end{Declaration}
\BeginIndex{Cmd}{AtAddToTocList}%
This command
adds the \PName{instructions} to a internal list of instructions that will be
processed whenever a file extension with the given \PName{owner} will be
added to the list of known extensions using \Macro{addtotoclist}.  The
optional argument is handled in the same way as with the command
\Macro{addtotoclist}. With an empty \PName{owner} you may
add \Parameter{instructions}, that will be processed at every successful
\Macro{addtotoclist}, after processing the instructions for the individual
owner.  While processing the \PValue{instructions},
\Macro{@currext}\IndexCmd{@currext}\important{\Macro{@currext}} will be set to
the extension of the currently added extension.
\begin{Example}
  \Package{tocbasic} itself uses
\begin{lstcode}
  \AtAddToTocList[]{%
    \expandafter\tocbasic@extend@babel
    \expandafter{\@currext}%
  }
\end{lstcode}
  to add every extension to the \Package{tocbasic}-internal babel handling of
  files.
\end{Example}

The two \Macro{expandafter} commands are needed, because the argument of
\Macro{tocbasic@extend@babel} has to be expanded!  See the description of
\Macro{tocbasic@extend@babel} at \autoref{sec:tocbasic.internals}%
, \autopageref{desc:tocbasic.cmd.tocbasic@extend@babel}
for more information.
\EndIndex{Cmd}{AtAddToTocList}%

\begin{Declaration}
  \Macro{removefromtoclist}\OParameter{owner}\Parameter{extension}
\end{Declaration}
\BeginIndex{Cmd}{removefromtoclist}%
This command
removes the \PName{extension} from the list of known extensions.  If the
optional argument, \OParameter{owner}, was given, the \PName{extension} will
only be removed if it was added by this \PName{owner}. See description of
\Macro{addtotoclist} for information of omitting optional argument. Note that
an empty \PName{owner} is not the same like omitting the optional argument,
but removes the \PName{extension} without any owner test.%
\EndIndex{Cmd}{removefromtoclist}%

\begin{Declaration}
  \Macro{doforeachtocfile}\OParameter{owner}\Parameter{instructions}
\end{Declaration}
\BeginIndex{Cmd}{doforeachtocfile}%
Until now you've learned to know commands that result in more safety in
handling file extensions, but also needs some additional effort. With
\Macro{doforeachtocfile}%^^A
\ you will win for this. The command provides to processes \PName{instructions}
for every known file extension of the given \PName{owner}.  While processing
the \PName{instructions} \Macro{@currext} is the extension of the current
file.  If you omit the optional argument, \OParameter{owner}, every known file
extensions independent from the owner will be used. If the optional argument
is empty, only file extensions with an empty owner will be processed.
\begin{Example}
  If you want to type out all known extensions, you may simply write:
\begin{lstcode}
  \doforeachtocfile{\typeout{\@currext}}
\end{lstcode}
  and if only the extensions of owner ``\PValue{foo}'' should be typed out:
\begin{lstcode}
  \doforeachtocfile[foo]{\typeout{\@currext}}
\end{lstcode}
\end{Example}
\EndIndex{Cmd}{doforeachtocfile}%

\begin{Declaration}
  \Macro{tocbasicautomode}
\end{Declaration}
\BeginIndex{Cmd}{tocbasicautomode}%
This command
redefines \LaTeX{} kernel macro \Macro{@starttoc} to add all not yet added
extensions to the list of known extensions and use \Macro{tocbasic@starttoc}
instead of \Macro{@starttoc}. See \autoref{sec:tocbasic.internals}%^^A
, \autopageref{desc:tocbasic.cmd.tocbasic@starttoc}
for more information about \Macro{tocbasic@starttoc} and \Macro{@starttoc}.

This means that after using \Macro{tocbasicautomode} every table of contents
or list of something, that will be generated using \Macro{@starttoc} will be
at least partially under control of \Package{tocbasic}. Whether or not this will
make the wanted result, depends on the individual table of contents and lists
of something. At least the \Package{babel} control extension for
all those tables of contents and lists of something will work. Nevertheless,
it would be better if the author of the corresponding class or package will
use \Package{tocbasic} explicitly. In that case additional advantages of
\Package{tocbasic} may be used that will be described at the following
sections.%
\EndIndex{Cmd}{tocbasicautomode}%

\section{Creating a Table of Contents or List of Something}
\label{sec:tocbasic.toc}

In the previous section you've seen commands to handle a list of known
extensions and to trigger commands while adding a new extension to this
list. You've also seen a command to do something for all known extensions or
all known extensions of one owner. In this section you will see commands to
handle the file corresponding with an extension or the list of known
extensions.

\begin{Declaration}
  \Macro{addtoeachtocfile}\OParameter{owner}\Parameter{content}
\end{Declaration}
\BeginIndex{Cmd}{addtoeachtocfile}%
This command
writes \PName{content} to the files of every known file extension of
\PName{owner} using \LaTeX{} kernel command \Macro{addtocontents}. If you omit
the optional argument, \PName{content} is written to the files of every known
file extension. Furthermore, the practical file name is built from
\Macro{jobname} and the file extension. While writing the \PName{content},
\Macro{@currext}\IndexCmd{@currext}\important{\Macro{@currext}} is the
extension of the currently handled file.
\begin{Example}
  You may add a vertical space of one text line to all toc-files.
\begin{lstcode}
    \addtoeachtocfile{%
      \protect\addvspace{\protect\baselineskip}%
    }
\end{lstcode}
  And if you want to do this, only for the toc-files of owner
  ``\PValue{foo}'':
\begin{lstcode}
    \addtoeachtocfile[foo]{%
      \protect\addvspace{\protect\baselineskip}%
    }
\end{lstcode}
\end{Example}
Commands, that shouldn't be expanded while writing, should be prefixed by
\Macro{protect} in the same way like they should be in the argument of
\Macro{addtocontents}.
\EndIndex{Cmd}{addtoeachtocfile}%

\begin{Declaration}
  \Macro{addxcontentsline}%
  \Parameter{extension}\Parameter{level}\OParameter{number}%^^A
  \Parameter{text}
\end{Declaration}
\BeginIndex{Cmd}{addxcontentsline}%
The command \Macro{addxcontentsline}
adds an entry of given \PName{level} to toc-file with \PName{extension}. If
the \Parameter{number} is empty or omitted the entry won't have a number for
the entry with the given \PName{text}. Entries without number may be left
aligned to the number of the numbered entries of the same \PName{level} or
indented like the text of the numbered entries of the same \PName{level},
depending on the \PValue{numberline} feature.

\begin{Example}
  Maybe you are not using a \KOMAScript{} class but need a not numbered
  chapter with entry to the table of contents. This may be done using
\begin{lstcode}
  \cleardoublepage
  \csname phantomsection\endcsname
  \addxcontentsline{toc}{chapter}
             {Chapters without Numbers}
  \chapter*{Chapters without Numbers}
  \markboth{Chapters without Numbers}{}
\end{lstcode}
  As you can see, you simply have to replace usual \Macro{addcontentsline} by
  \Macro{addxcontentsline} to support the \Package{tocbasic} feature
  \PValue{numberline}.
\end{Example}

Note, that \Macro{addxcontentsline} uses
\Macro{add\PName{level}\PName{extension}entry} if such a macro exists and
\Macro{tocbasic@addxcontentsline} otherwise. Therefore you cannot define
a macro \Macro{add\PName{level}\PName{extension}entry} using
\Macro{addxcontentsline} but \Macro{tocbasic@addxcontentsline}.

It is recommended to use \Macro{addxcontentsline} instead of
\Macro{addcontentsline} whenever possible.%
\EndIndex{Cmd}{addxcontentsline}

\begin{Declaration}
  \Macro{addcontentslinetoeachtocfile}\OParameter{owner}\Parameter{level}%^^A
  \Parameter{contentsline}\\
  \Macro{addxcontentslinetoeachtocfile}\OParameter{owner}%^^A
  \Parameter{level}\OParameter{number}\Parameter{text}
\end{Declaration}
\BeginIndex{Cmd}{addcontentslinetoeachtocfile}%
\BeginIndex{Cmd}{addxcontentslinetoeachtocfile}%
The first command
is something like \Macro{addcontentsline} from \LaTeX{} kernel. In difference
to that it writes the \PName{contentsline} not only
into one file, but into all files of all known file extensions or of all known
file extensions of a given owner.

The Command \Macro{addxcontentslinetoeachtocfile}%^^A
\ is similar but uses
\Macro{addxcontentsline} instead of \Macro{addcontentsline} and
therefore supports \Package{tocbasic} feature \PValue{numberline}.
\begin{Example}
  You are a class author and want to write the chapter entry not only to the
  table of contents toc-file but to all toc-files, while \texttt{\#1} is the
  title, that should be written to the files.
\begin{lstcode}
    \addxcontentslinetoeachtocfile
              {chapter}[\thechapter]{#1}%
\end{lstcode}
  In this case the current chapter number should be expanded while writing
  into the file. So it isn't protected from expansion using \Macro{protect}.
\end{Example}
While writing \Macro{@currext}\IndexCmd{@currext}\important{\Macro{@currext}}
is the file extension of the file into which \PName{contentsline} will be
written.

It is recommended to use \Macro{addxcontentslinetoeachtocfile} instead
of \Macro{addcontentslinetoeachtocfile} whenever possible.
\EndIndex{Cmd}{addxcontentslinetoeachtocfile}%
\EndIndex{Cmd}{addcontentslinetoeachtocfile}%

\begin{Declaration}
  \Macro{listoftoc}\OParameter{list of title}\Parameter{extension}%^^A
\\
  \Macro{listoftoc*}\Parameter{extension}%^^A
\\
  \Macro{listofeachtoc}\OParameter{owner}%^^A
\\
  \Macro{listof\PName{file-extension}name}
\end{Declaration}
\BeginIndex{Cmd}{listoftoc*}%
\BeginIndex{Cmd}{listoftoc}%
\BeginIndex{Cmd}{listofeachtoc}%
\BeginIndex{Cmd}{listof\PName{file-extension}name}%
These commands
may be used to set the ``list of'' corresponding to file
extension. The\important{\Macro{listoftoc*}} star version \Macro{listoftoc*}
needs only one argument, the extension of the file. It does setup the vertical
and horizontal spacing of paragraphs, calls before hooks, reads the file, and
last but not least calls the after hooks.  You may interpret it as direct
replacement of the \LaTeX{} kernel macro
\Macro{@starttoc}\IndexCmd{@starttoc}\important{\Macro{@starttoc}}.

The\important{\Macro{listoftoc}} version without star, sets the whole file
with title, optional table of contents entry, and running heads. If the
optional argument \OParameter{list of title} was given, it will be used as
title term, optional table of contents entry and running head. Please
note\textnote{Attention!}: If the optional argument is empty, this term will
be empty, too! If you omit the optional argument, but
\Macro{listof\PName{extension}name} was defined, that will be used. If that is
also not defined, a standard ersatz name will be used and reported by a
warning message.

The\important{\Macro{listofeachtoc}} command \Macro{listofeachtoc} outputs all
lists of something of the given \PName{owner} or of all known file
extensions. Thereby\textnote{Attention!}
\Macro{listof\PName{file-extension}name} should be defined to get the correct
titles.

It\textnote{Hint!} is recommended to define
\Macro{listof\PName{file-extension}name} for all used file extensions, because
the user itself may use \Macro{listofeachtoc}.
\begin{Example}
  Assumed, you have a new ``list of algorithms'' with extension \PValue{loa}
  and want to show it:
\begin{lstcode}
  \listoftoc[List of Algorithms]{loa}
\end{lstcode}
  will do it for you. But maybe the ``list of algorithms'' should not be set
  with a title. So you may use
\begin{lstcode}
  \listof*{loa}
\end{lstcode}
  Note that in this case no entry at the table of contents will be created,
  even if you'd used the setup command above.
  See command \Macro{setuptoc}
  at \autopageref{desc:tocbasic.cmd.setuptoc}
  for more information about the
  attribute of generating entries into the table of contents using
  \Macro{setuptoc}.

  If you've defined
\begin{lstcode}
  \newcommand*{\listofloaname}{%
    List of Algorithms%
  }
\end{lstcode}
  before, then
\begin{lstcode}
  \listoftoc{loa}
\end{lstcode}
  would be enough to print the list of algorithms with the wanted heading. For
  the user it may be easier to operate, if you'd define
\begin{lstcode}
  \newcommand*{\listofalgorithms}{\listoftoc{loa}}
\end{lstcode}
  additionally.
\end{Example}

Because\textnote{Attention!} \LaTeX{} normally opens a new file for each of
those lists of something immediately, the call of each of those commands may
result in an error like:
\begin{lstoutput}
  ! No room for a new \write .
  \ch@ck ...\else \errmessage {No room for a new #3}
                                                    \fi
\end{lstoutput}
if there are no more write handles left. Loading package
\Package{scrwfile}\important{\Package{scrwfile}}\IndexPackage{scrwfile}
(see \autoref{cha:scrwfile})
may solve this problem.

Sometimes it's useful, to process \PName{instructions} immediately before
reading the helper file of a list of something.
These commands
may be used to process \PName{instructions} before or after loading the file
with given \PName{extension} using \Macro{listoftoc*}, \Macro{listoftoc}, or
\Macro{listofeachtoc}.  If you omit the optional argument (or set an empty
one) the general hooks will be set. The general before hook will be called
before the individuel one and the general after hook will be called after the
individuel one. While calling the hooks
\Macro{@currext}\IndexCmd{@currext}\important{\Macro{@currext}} is the
extension of the toc-file and should not be changed.

An example\textnote{Example} for usage of \Macro{AfterStartingTOC} may be

\Macro{listoftoc*} or \Macro{listoftoc}. If you omit the optional argument (or
set an empty one) the general hooks will be set. The general before hook will
be called before the individuel one and the general after hook will be called
after the individuel one. While calling the hooks
\Macro{@currext}IndexCmd{@currext}\important{\Macro{@currext}} is the

  \Macro{MakeMarkcase}\Parameter{text}
\end{Declaration}
\BeginIndex{Cmd}{MakeMarkcase}%
Whenever \Package{tocbasic} sets a mark for a running head, The text of the
mark will be an argument of \Macro{MakeMarkcase}%^^A
. This command may be used, to change the case of the letters at the running
head if wanted. The default is, to use
\Macro{@firstofone}\IndexCmd{@firstofone}\important{\Macro{@firstofone}} for
\KOMAScript{} classes. This means the text of the running head will be set
without change of case.
\Macro{MakeUppercase}\IndexCmd{MakeUppercase}\important{\Macro{MakeUppercase}}
will be used for all other classes. If you are the class author you may define
\Macro{MakeMarkcase} on your own. If \Package{scrlayer} or another package,
that defines \Macro{MakeMarkcase} will be used, \Package{tocbasic} will not
overwrite that definition.
\begin{Example}
  For incomprehensible reasons, you want to set the running heads in lower
  case letters only. To make this automatically for all running heads, that
  will be set by \Package{tocbasic}, you define:
\begin{lstcode}
  \let\MakeMarkcase\MakeLowercase
\end{lstcode}
\end{Example}
Please\textnote{Hint!} allow me some words about \Macro{MakeUppercase}, First
of all this command isn't fully expandable. This means, that problems may
occur using it in the context of other commands. Beyond that typographers
accord, that whenever setting whole words or phrases in capitals, letter
spacing is absolutely necessary. But correct letter spacing of capitals
shouldn't be done with a fix white space between all letters. Different pairs
of letters need different space between each other. Additional some letters
build holes in the text, that have to be taken into account. Packages like
\Package{ulem} or \Package{soul} doesn't provide this and
\Macro{MakeUppercase} doesn't do anything like this. Also automatic letter
spacing using package \Package{microtype} is only one step to a less-than-ideal
solution, because it cannot recognize and take into account the glyphs of the
letters. Because of this\textnote{Attention!} typesetting whole words and
phrases is expert work and almost ever must be hand made. So average users are
recommended to not do that or to use it only spare and not at exposed places
like running heads.%

\BeginIndex{Cmd}{deftocheading}%
The package \Package{tocbasic} contains a standard definition for typesetting
headings of tables of contents or lists of something. This standard definition
is configurable by several features, described at \Macro{setuptoc} next. But
if all those features are not enough, an alternative heading command may be
defined using \Macro{deftocheading}%^^A
. Thereby \PName{file extension} is the file extension of the corresponding
helper file. The \PName{definition} of the heading command may use one single
parameter \PValue{\#1}. While calling the newly defined command inside of
\Macro{listoftoc} or \Macro{listofeachtoc} that \PValue{\#1} will be replaced by the
corresponding heading term.

\BeginIndex{Cmd}{setuptoc}%
\BeginIndex{Cmd}{unsettoc}%
This commands
set up and unset features bound to an \PName{file extension}. The
\PName{feature list} is a comma seperated list of single
features. \Package{tocbasic} does know following features:
\begin{description}
\item[\texttt{leveldown}] uses not the top level heading below
  \Macro{part}\,---\,\Macro{chapter} if available, \Macro{section}
  otherwise\,---\,but the first sub level. This feature will be evaluated by
  the internal heading command. On the other hand, if an user defined heading
  command has been made with \Macro{deftocheading}, that user is responsible
  for the evaluation of the feature. The \KOMAScript{} classes set this
  feature using option
  \OptionValue{listof}{leveldown}important{\OptionValue{listof}{leveldown}}%
  \IndexOption{listof~=\PValue{leveldown}} for all file extensions of the
  owner \PValue{float}.
\item[\texttt{nobabel}] prevents usage of the language switch of
  \Package{babel}\IndexPackage{babel} at the helper file with the
  corresponding \PName{file extension}. This feature should be used only for
  helper files, that contain text in one language only. Changes of the
  language inside of the document will not longer regarded at the helper
  file. Package
  \Package{scrwfile}\important{\Package{scrwfile}}\IndexPackage{scrwfile} uses
  this feature also for clone destinations, because those will get the
  language change from the clone source already.
\item[\texttt{noparskipfake}] prevents\ChangedAt{v3.17}{\Package{tocbasic}}
  usage of an extra \Length{parskip} before switching \Length{parskip} off. In
  general, the consequence of this feature for documents using paragraph
  distance is less vertical space between heading and first entry than between
  normal headings and normal text.
\item[\texttt{noprotrusion}] prevents\ChangedAt{v3.10}{\Package{tocbasic}}
  disabling character protrusion at the lists of something. Character
  protrusion at the lists will be disabled by default if package
  \Package{microtype}\IndexPackage{microtype} or another package, that
  supports \Macro{microtypesetup}\IndexCmd{microtypesetup}, was loaded. So if
  you want protrusion at the lists, you have to set this feature. But
  note\textnote{Attention!}, that with character protrusion entries at the
  list may be set wrong. This is a known issue of character protrusion.
\item[\texttt{numbered}] uses a numbered heading for the table of contents or
  list of something and because of this also generates an entry to the table
  of contents. This feature will be evaluated by the internal heading
  command. On the other hand, if an user defined heading command has been made
  with \Macro{deftocheading}, that user is responsible for the evaluation of
  the feature. The \KOMAScript{} classes set this feature using option
  \OptionValue{listof}{numbered}\important{\OptionValue{listof}{numbered}}%
  \IndexOption{listof~=\PValue{numbered}} for all file extensions of the owner
  \PValue{float}.
\item[\texttt{numberline}] \leavevmode\ChangedAt{v3.12}{\Package{tocbasic}}%
  redefines \Macro{nonumberline} to use \Macro{numberline}. With this the not
  numbered entries generated by \KOMAScript{} or using \Macro{nonumberline} at
  the very beginning of the last argument of \Macro{addcontentline} will also
  be indented like numbered entries of the same type.
\item[\texttt{onecolumn}] \leavevmode\ChangedAt{v3.01}{\Package{tocbasic}}%
  typesets the corresponding table of contents or list of something with
  internal one column mode of
  \Macro{onecolumn}\IndexCmd{onecolumn}. This\textnote{Attention!} will be
  done only, if the corresponding table of contents or list of something
  doesn't use feature \PValue{leveldown}\important{\PValue{leveldown}}. The
  \KOMAScript{} classes \Class{scrbook} and \Class{scrreprt} activate this
  feature with \Macro{AtAddToTocList} (see \autoref{sec:tocbasic.basics}%^^A
  , \autopageref{desc:tocbasic.cmd.AtAddToTocList}%^^A
  ) for all lists of something with owner \PValue{float} or with themselves as
  owner. With this, e.\,g., the table of contents, the list of figures and the
  list of tables of both classes will be single columned automatically. The
  multiple-column-mode of package \Package{multicol}\IndexPackage{multicol}
  will not be recognized or changed by this option.
\item[\texttt{totoc}] writes the title of the corresponding table of contents
  or the list of something to the table of contents. This feature will be
  evaluated by the internal heading command. On the other hand, if an user
  defined heading command has been made with \Macro{deftocheading}, that user
  is responsible for the evaluation of the feature. The \KOMAScript{} classes
  set this feature using option
  \OptionValue{listof}{totoc}\important{\OptionValue{listof}{totoc}}%
  \IndexOption{listof~=\PValue{totoc}} for all file extensions of the owner
  \PValue{float}.
\end{description}
Classes and packages may know features, too, e.\,g, the \KOMAScript{} classes
know following additional features:
\begin{description}
\item[\texttt{chapteratlist}] activates special code to be put into the list
  at start of a new chapter. This code may either be vertical space or the
  heading of the chapter.
  See \Option{listof}\IndexOption{listof}\important{\Option{listof}} in
  \autoref{sec:maincls.floats}, \autopageref{desc:maincls.option.listof} for
  more information about such features.
\end{description}
\begin{Example}
  Because \KOMAScript{} classes use \Package{tocbasic} for the list of figures
  and list of tables, there's one more way to remove chapter structuring at
  those:
\begin{lstcode}
  \unsettoc{lof}{chapteratlist}
  \unsettoc{lot}{chapteratlist}
\end{lstcode}

  And if you want to have the chapter structuring of the \KOMAScript{} classes
  at your own list of algorithms with \PName{file extension} ``\PValue{load}''
  from the previous examples, you may use
\begin{lstcode}
  \setuptoc{loa}{chapteratlist}
\end{lstcode}
  And if classes with \Macro{chapter} should also force single column mode for
  the list of algorithms you may use
\begin{lstcode}
  \ifundefinedorrelax{chapter}{}{%
    \setuptoc{loa}{onecolumn}%
  }
\end{lstcode}
  Usage of \Macro{ifundefinedorrelax} presumes package \Package{scrbase}%^^A
  \ (see \autoref{sec:scrbase.if},
  \autopageref{desc:scrbase.cmd.ifundefinedorrelax})%^^A
  .

  It\textnote{Hint!} doesn't matter if you're package would be used with
  another class. You should never the less set this feature. And if the other
  class would also recognize the feature your package would automatically use
  the feature of that class.
\end{Example}
As you may see, packages, that use \Package{tocbasic}, already provide several
interesting features, without the need of a lot of implementation effort. Such
an effort would be needed only without \Package{tocbasic} and because of this,
most packages currently lack of such features.%

\section{Internal Commands for Class and Package Authors}
\label{sec:tocbasic.internals}

Commands with prefix \Macro{tocbasic@} are internal but class and package
authors may use them. But even if you are a class or package author you
should not change them!

\begin{Declaration}
  \Macro{tocbasic@extend@babel}\Parameter{file extension}
\end{Declaration}
\BeginIndex{Cmd}{tocbasic@extend@babel}%
The Package \Package{babel}\IndexPackage{babel}
(see \cite{package:babel})
respectively a \LaTeX{} kernel that has been extended by the language
management of \Package{babel} writes instructions to change the language
inside of the files with the file extensions \File{toc}, \File{lof}, and
\File{lot} into those files at every change of the current language
either at the begin of the document or inside the document. Package
\Package{tocbasic} extends this mechanism with
\Macro{tocbasic@extend@babel}
to be used for other file extensions too. Argument \PName{file extension} has
to be expandable! Otherwise the meaning of the argument may change until it
will be used really.

Normally this command will be used by default for every \PName{file extension}
that will be added to the list of known extensions using
\Macro{addtotoclist}. The may be suppressed using feature
\PValue{nobabel}\important{\PValue{nobabel}} (see \Macro{setuptoc},
\autoref{sec:tocbasic.toc}%^^A
, \autopageref{desc:tocbasic.cmd.setuptoc}%^^A
). For the file extensions \File{toc}, \File{lof}, and \File{lot} this will be
done automatically by \Package{tocbasic} to avoid double language switching in
the corresponding files.

Normally there isn't any reason to call this command yourself. But there may
by lists of something, that should not be under control of \Package{tocbasic},
and to are not in \Package{tocbasic}'s list of known file extensions, but
nevertheless should be handled by the language change mechanism of
\Package{babel}. The command may be used explicitly for those files. But pleas
note, that this should be done only once per file extension!%
\EndIndex{Cmd}{tocbasic@extend@babel}%

\begin{Declaration}
  \Macro{tocbasic@starttoc}\Parameter{extension}
\end{Declaration}
\BeginIndex{Cmd}{tocbasic@starttoc}
This command
is something like the \LaTeX{} kernel macro
\Macro{@starttoc}\IndexCmd{@starttoc}\important{\Macro{@starttoc}}.  It's the
command behind \Macro{listoftoc*} (siehe \autoref{sec:tocbasic.toc}%^^A
, \autopageref{desc:tocbasic.cmd.listoftoc*}%^^A
). Authors of classes or packages who want to participate from the advantages
of \Package{tocbasic} should at least use this command. Nevertheless it's
recommended to use \Macro{listoftoc}. Command \Macro{tocbasic@starttoc}
internally uses \Macro{\@starttoc}, but sets
\Length
{parskip}\IndexLength{parskip}\important{\Length{parskip}\\
  \Length{parindent}\\
  \Length{parfillskip}} and
\Length
{parindent}\IndexLength{parindent} to 0 and
\Length
{parfillskip} to 0 until infinite before. Moreover,
\Macro{@currext}\important{\Macro{@currext}}\IndexCmd{@currext} will be set to
the file extension of the current helper file, so this will be available while
the execution of the hooks, that will be done before and after reading the
helper files.

Because\textnote{Attention!} of \LaTeX{} will immediately open a new helper
file for writing after reading that file, the usage of
\Macro{tocbasic@starttoc} may result in an error message like
\begin{lstoutput}
  ! No room for a new \write .
  \ch@ck ...\else \errmessage {No room for a new #3}
                                                    \fi
\end{lstoutput}
if there are no more unused write handles. This may be solved, e.\,g., using
package
\Package{scrwfile}\important{\Package{scrwfile}}\IndexPackage{scrwfile}.
See \autoref{cha:scrwfile} for more information about that package.%
\EndIndex{Cmd}{tocbasic@starttoc}

  \Macro{tocbasic@@before@hook}\\
  \Macro{tocbasic@@after@hook}
\end{Declaration}
\BeginIndex{Cmd}{tocbasic@@before@hook}%
\BeginIndex{Cmd}{tocbasic@@after@hook}%
The hook \Macro{tocbasic@@before@hook} will be executed immediately before
reading a helper file for a table of contents or list of something even
before execution of the instructions of a \Macro{BeforeStartingTOC}
command. It is permitted to extend this hook using
\Macro{g@addto@macro}\IndexCmd{g@addto@macro}.

Similarly \Macro{tocbasic@@after@hook} will be executed immediately after
reading such a helper file and before execution of instructions of
\Macro{AfterStartingTOC}. It is permitted to extend this hook using
\Macro{g@addto@macro}\IndexCmd{g@addto@macro}.

\KOMAScript{} uses these hooks, to provide the automatic width calculation of
the place needed by heading numbers. Only classes and packages should use
these hooks. Users\textnote{Attention!} should really use
\Macro{BeforeStartingTOC} and \Macro{AfterStartingTOC} instead. Authors of
packages should also favor those commands! These hooks shouldn't be used to
generate any output!

If neither\textnote{Attention!} \Macro{listofeachtoc} nor \Macro{listoftoc}
nor \Macro{listoftoc*} are used for the output of a table of contents or list
of something, the hooks should be executed explicitly.%

These hooks are processed after \Macro{tocbasic@@before@hook}, respectively
before \Macro{tocbasic@@after@hook} before and after loading the helper file
with the corresponding file \PName{extension}. Authors\textnote{Attention!}
of classes and packages should never manipulate them! But if
neither\textnote{Attention!} \Macro{listofeachtoc} nor \Macro{listoftoc} nor

This command
is used by \Macro{listoftoc} to set the heading of the list, either the
default heading or the individually defined heading. If you define your own
list command not using \Macro{listoftoc} you may use
\Macro{tocbasic@listhead}. In this case you should define
\Macro{@currext}\important{\Macro{@currext}}\IndexCmd{@currext} to be the file

\section{A Complete Example}
\label{sec:tocbasic.example}

This section will show you a complete example of a user defined floating
environment with list of that kind of floats and \KOMAScript{} integration
using \Package{tocbasic}. This example uses internal commands, that have a
``\texttt{@}'' in their name. This means\textnote{Attention}, that the code
has to be put into a own package or class, or has to be placed between
\Macro{makeatletter}\important[i]{\Macro{makeatletter}\\\Macro{makeatother}}%
\IndexCmd{makeatletter} and \Macro{makeatother}\IndexCmd{makeatother}.

First\textnote{environment} of all, a new floating environment will be
needed. This could simply be done using:
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \newenvironment{remarkbox}{%
    \@float{remarkbox}%
  }{%
    \end@float
  }
\end{lstcode}
To the new environment is named \Environment{remarkbox}.

Each\textnote{placement} floating environment has a default
placement. This is build by some of the well known placement options:
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \newcommand*{\fps@remarkbox}{tbp}
\end{lstcode}
So, the new floating environment should be placed by default only either at
the top of a page, at the bottom of a page, or on a page on its own.

Floating\textnote{type} environments have a numerical floating
type. Environments with the same active bit at the floating type cannot change
their order. Figures and table normally use type~1 and 2. So a figure that
comes later at the source code than a table, may be output earlier than the
table and vica versa.
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \newcommand*{\ftype@remarkbox}{4}
\end{lstcode}
The new environment has floating type~4, so it may pass figures and floats and
may be passed by those.

The\textnote{number} captions of floating environment also have numbers.
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \newcounter{remarkbox}
  \newcommand*{\remarkboxformat}{%
    Remark~\theremarkbox\csname autodot\endcsname}
  \newcommand*{\fnum@remarkbox}{\remarkboxformat}
\end{lstcode}
Here first a new counter has been defined, that is independent from chapters
or the counters of other structural levels. \LaTeX{} itself also defines
\Macro{theremarkbox} with the default Arabic representation of the counter's
value. Afterwards this has been used defining the formatted output of the
counter. Last this formatted output has been used for the output of the
environment number of the \Macro{caption} command.

Floating\textnote{file extension} environments have lists of themselves and
those need a helper file with name \Macro{jobname} and a file extension.
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \newcommand*{\ext@remarkbox}{lor}
\end{lstcode}
The file extension of the helper file for the list of
\Environment{remarkbox}es is ``\File{lor}''.

This was the definition of the floating environment. But the list of this new
environment's captions is still missing. To reduce the implementation effort
package \Package{tocbasic} will be used for this. This will be loaded using
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \usepackage{tocbasic}
\end{lstcode}
inside of document preambles. Authors of classes or packages would use
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \RequirePackage{tocbasic}
\end{lstcode}
instead.

Now\textnote{extension} we register the file name extension for package
\Package{tocbasic}:
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \addtotoclist[float]{lor}
\end{lstcode}
Thereby the owner \PValue{float} has been used, to allude all further
\KOMAScript{} options for lists of something also to the new one.

Next\textnote{title} we define a title or heading for the list of
\Environment{remarkbox}es:
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \newcommand*{\listoflorname}{List of Remarks}
\end{lstcode}
You may use package \Package{scrbase} to additionally support titles in other
languages than English.

Also\textnote{entry} a command is needed to define the layout of the entries
to the list of remarks:
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \newcommand*{\l@remarkbox}{\l@figure}
\end{lstcode}
Here simply the entries to the list of remarks get the same layout like the
entries to the list of figure. This would be the easiest solution. A more
explicit would be, e.\,g.,
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \newcommand*{\l@remarkbox}{\@dottedtocline{1}{1em}{1.5em}}
\end{lstcode}

Additionally\textnote{chapter entry} you may want structure the list of
remarks depending on chapters.
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \setuptoc{lor}{chapteratlist}
\end{lstcode}
The \KOMAScript{} classes provide that feature and may other classes do so
too. Unfortunately the standard classes do not.

This\textnote{list of remarks} would already be enough. Now, users may already
select different kinds of headings either using the corresponding options of
the \KOMAScript{} classes, or \Macro{setuptoc}, e.\,g., with or without entry
in the table of contents, with or without number. But a simply
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \newcommand*{\listofremarkboxes}{\listoftoc{lor}}
\end{lstcode}
may make the usage a little bit easier again.

As you've seen only five commands refers to the list of remarks. Only three of
them are necessary. Nevertheless the new list of remarks already provides
optional numbering of the heading and optional not numbered entry into the
table of contents. Optional even a lower document structure level may be used
for the heading. Running headers are provides with the \KOMAScript{} classes,
the standard classes, and all classes that explicitly support
\Package{tocbasic}. Supporting classes even pay attention to this new list of
remarks at every new \Macro{chapter}. Even changes of the current language are
handled inside the list of remarks like they will inside the list of figures
or inside the list of tables.

Moreover.\textnote{additional features} an author of a package may add more
features. For example, options to hide \Macro{setuptoc} from the users may be
added. On the other hand, the \Package{tocbasic} manual may be referenced to
describe the corresponding features. The advantage of this would be that user
would get information about new features provides by \Package{tocbasic}. But
if the user should be able to set the features of the remarks even without
knowledge about the file extension \File{lor} a simple
\begin{lstcode}[belowskip=\dp\strutbox plus 1pt]
  \newcommand*{\setupremarkboxes}{\setuptoc{lor}}
\end{lstcode}
would be enough to use a list of features argument to
\Macro{setupremarkboxes} as list of features of file extension \File{lor}.

\section{Everything with One Command Only}
\label{sec:tocbasic.highlevel}

The example from the previous section shows, that using \Package{tocbasic} to
define floating environments and lists with the captions of those floating
environments is easy. The following example will show, that is may be even
easier.

\begin{Declaration}
  \Macro{DeclareNewTOC}\OParameter{options}\Parameter{extension}
\end{Declaration}
\BeginIndex{Cmd}{DeclareNewTOC}%
This command
declares\ChangedAt{v3.06}{\Package{tocbasic}} in one step only a new list of
something, the heading of that list, the term used for the entries to the
list, and to manage the file name \PName{extension}. Additionally optional
floating and non-floating environments may be defined, and inside of both such
environments \Macro{caption}\important{\Macro{caption}}\IndexCmd{caption} may
be used. The additional features \Macro{captionabove}\important[i]{%
  \Macro{captionabove}\\
  \Macro{captionbelow}}, \Macro{captionbelow}, and \Environment{captionbeside}
of the \KOMAScript{} classes
(see \autoref{sec:maincls.floats})
may also be used inside of those environments.

Argument \PName{extension} is the file name extension of the helper file, that
represents the list of something. See \autoref{sec:tocbasic.basics} for more
information about this. This argument is mandatory and must not be empty!

Argument \PName{options} is a comma separated list, like you know it from,
e.\,g., \Macro{KOMAoptions}%
\ (see \autoref{sec:typearea.options})%^^A
. Nevertheless\textnote{Attention!}, those options cannot be set using
\Macro{KOMAoptions}\IndexCmd{KOMAoptions}! An overview of all available
options

    environment is the value of \PName{type} with postfix ``\PValue{-}''.%
  }%
  \entry{\KOption{owner}\PName{string}}{%
    The owner as described in the sections before. If no owner was given owner
    \PValue{float} will be used.%
  }%
  \entry{\KOption{type}\PName{string}}{%
    sets the type of the new declared list. The type will be used e.\,g. to
    defined a \Macro{listof}\PName{string}. If no type is set up the extension
    from the mandatory argument will be used.%
  }%
  \entry{\KOption{types}\PName{string}}{%
    the plural of the type. If no plural was given the value of \PValue{type}
    with addendum ``s'' will be used.%

\begin{Example}
  Using \Macro{DeclareNewTOC} reduces the example from
  \autoref{sec:tocbasic.example} to:
\begin{lstcode}
  \DeclareNewTOC[%
    type=remarkbox,%
    types=remarkboxes,%
    float,% define a floating environment
    floattype=4,%
    name=Remark,%
    listname={List of Remarks}%
  ]{lor}
  \setuptoc{lor}{chapteratlist}
\end{lstcode}
  Beside environments \Environment{remarkbox} and \Environment{remarkbox*} the
  counter
\Counter
  {remarkbox}, the commands \Macro{theremarkbox},
  \Macro{remarkboxname}, and \Macro{remarkboxformat} that are used for
  captions; the commands \Macro{listremarkboxnames} and
  \Macro{listofremarkboxes} that are used at the list of remarks; and some
  internal commands that depends on the file name extension \File{lor} are
  defined. If the package should use a default for the floating type, option
  Option{floattype} may be omitted. If option \Option{nonfloat} will be used
  additionally, then a non-floating environment \Environment{remarkbox-} will
  be also defined. You may use \Macro{caption}\IndexCmd{caption} inside of
  that non-floating environment as usual for floating environments.
  \hyperref[tab:tocbasic.comparison]{Figure~\ref*{tab:tocbasic.comparison}}
  showes a comparison of the commands, counters and environments of the
  example environment \Environment{remarkbox} and of the commands, counters
  and environments for figures.%

  And now a possible usage of the example environment:
\begin{lstcode}
  \begin{remarkbox}
    \centering
    Equal should be typeset equally
    and with equal formatting.
    \caption{First theorem of typography}
    \label{rem:typo1}
  \end{remarkbox}
\end{lstcode}
  A segment of an example page with this environment could be:
  \begin{center}\footnotesize
    \begin{tabular}
      {|!{\hspace{.1\linewidth}}p{.55\linewidth}!{\hspace{.1\linewidth}}|}
      \\
      \centering
      Equal should be typeset equally
      and with equal formatting.\\[\abovecaptionskip]
