% \begin{abstract}
% A long time ago
% \href{https://www.sourceforge.net/project/koma-script}{\KOMAScript} was
% more or less just a collection of replacements for the three standard
% classes \cls*{article}, \cls*{book} and \cls*{report}. Replacing a
% standard class with a
% \href{https://www.sourceforge.net/project/koma-script}{\KOMAScript} class
% was easy, even if users used a lot of additional packages. Over the years,
% the author has added many new features and user interfaces to the
% classes. This also led to completely different implementation of the
% sectioning commands. But some packages depend on an implementation similar
% to the standard classes.
%
% Package \pkg*{standardsectioning} implements these commands with the code
% of the standard classes and also deactivates parts of the
% \href{https://www.sourceforge.net/project/koma-script}{\KOMAScript} user
% interface, which should not be used with these changes. These are more or
% less all commands to configure sectioning commands. It also reverts some
% internal macros of
% \href{https://www.sourceforge.net/project/koma-script}{\KOMAScript}.

\section{What are the typical reasons for using package
\texorpdfstring{\pkg*{standardsectioning}}{standardsectioning} and how to do
it?}
\label{sec:reasons}
Sometimes replacing a standard class by a
\href{https://komascript.de/}{\KOMAScript} class results in new errors,
because of incompatibility of some of the packages or the already existing
preamble code with these classes. In such a case, you first should try out
package \pkg{scrhack} without passing any option to that package. Package
\pkg{scrhack} should be the first package after loading the document class, or
even be loaded \emph{before} the document class using \cs{RequirePackage}
instead of \cs{usepackage}. If this already fixes the issue, you can try to
find out which of the replacements and enhancements loaded by \pkg{scrhack}
solved the issue and load only these.
Only if you cannot fix the issue this kind you can try loading
\pkg*{standardsectioning} either also using \pkg{scrhack} with
corresponding options (see \cite{pkg:scrhack:manual}) or just loading
\pkg*{standardsectioning}.
Such errors happen, e.g., because
\pkg{titlesec}\index{Packages:>\pkg{titlesec}} makes assumptions about the
definition of the sectioning commands that simply do not apply to the
\href{https://komascript.de/}{\KOMAScript} classes. This leads, e.g., in the
following example:
\begin{verbatim}
\documentclass{scrartcl}
\usepackage{titlesec}
\begin{document}
\section{Test Section}
Test text.
\end{document}
\end{verbatim}
to the error message:
\begin{verbatim}
Package titlesec Error: No format for this command.
See the titlesec package documentation for explanation.
Type H <return> for immediate help.
...
l.4 \section{Test Section}
\end{verbatim}
Several other errors can happen with combinations of \pkg{titlesec} and
\href{https://komascript.de/}{\KOMAScript} classes. Best solution for this,
would be to not use \pkg{titlesec} and instead use the class' interface to
configure the sectioning commands, e.g., \cs{RedeclareSectionCommand},
\cs{setkomafont}, or redefining \cs{sectionlinesformat}. See
\cite{pkg:koma-script:manual:en} or \cite{pkg:koma-script:manual:de} for more
information. But if you do not use any of the enhanced sectioning features of
the \href{https://komascript.de/}{\KOMAScript} classes, a first-aid workaround
would be to load package \pkg*{standardsectioning} immediately \emph{after}
the class:
\begin{verbatim}
\documentclass{scrartcl}
\usepackage{standardsectioning}
\usepackage{titlesec}
\begin{document}
\section{Test Section}
Test text.
\end{document}
\end{verbatim}
Among other things, this redefines the sectioning commands to be compatible
with the standard classes.
\begin{description}\sloppy
\item[But note:] \leavevmode
\marginline{\raisebox{\dimexpr\ht\strutbox-\height\relax}{\Huge\textcolor{red}{!}}}%
This also means, that all the enhancements to these commands are broken! You
cannot use \cs{DeclareSectionCommand}, \cs{RedeclareSectionCommand},
\cs{DeclareNewSectionCommand}, \cs{ProvideSectionCommand},
\cs{DeclareSectionCommands}, \cs{RedeclareSectionCommands},
\cs{DeclareNewSectionCommands}, or \cs{ProvideSectionCommands} any
longer. Other commands like \cs{partformat}, \cs{chapterformat},
\cs{sectionformat}, \cs{subsectionformat}, \cs{subsubsectionformat},
\cs{paragraphformat}, \cs{subparagraphformat} and many more are not used
anymore.
\end{description}
Sometimes a wrapper classes loads a \href{https://komascript.de/}{\KOMAScript}
class and than also loads a package like \pkg{titlesec}. To load
\pkg*{standardsections} immediately after the class, you should use the
generic class hook available from \LaTeX{} 2020-10-01:
\begin{verbatim}
\AddToHook{class/scrartcl/after}{\RequirePackage{standardsectioning}}
\AddToHook{class/scrbook/after}{\RequirePackage{standardsectioning}}
\AddToHook{class/scrreprt/after}{\RequirePackage{standardsectioning}}
\end{verbatim}
These lines should be placed \texttt{before} \cs{documentclass}. If you are
using an older \LaTeX{} version you can use
\href{https://komascript.de/}{\KOMAScript} package \pkg{scrlfile} to do the
same:
\begin{verbatim}
\RequirePackage{scrlfile}
\AfterClass{scrartcl}{\RequirePackage{standardsectioning}}
\AfterClass{scrbook}{\RequirePackage{standardsectioning}}
\AfterClass{scrreport}{\RequirePackage{standardsectioning}}
\end{verbatim}
also \emph{before} loading the class.
\section{How to select the correct sectioning code, if the automatism fails?}
\label{sec:options}
By default, the package uses an automatism to decide which code of which
standard class should be used. If the \KOMAScript{} class \cls{scrartcl} is
detected, automatically the code of \cls{article} is used. If the
\KOMAScript{} class \cls{scrreprt} is detected, automatically the code of
\cls{report} is used. If the \KOMAScript{} class \cls{scrbook} is detected,
automatically the code of \cls{book} is used. If none of these classes is
detected, the existence of two commands is used. If \cs{chapter} is not
defined, the code of \cls{article} is used. If \cs{chapter} is defined, but
\cs{frontmatter} is not defined, the code of \cls{report} is used. If both
\cs{chapter} and \cs{frontmatter} are defined, the code of \cls{book} is used.
%\DescribeOption{article}
%\DescribeOption{book}
%\DescribeOption{report}
Very seldom this automatism fails and the wrong code is used, which results in
error messages or printing mistakes. In this case you can load package
\pkg*{standardsectioning} with one of the options \opt{article}, \opt{report}
or \opt{book} to force the usage of the sectioning code of either
\cls{article}, \cls{report}, or \cls{book}. This could, e.g., be needed, if
you are using a class, that defines \cs{chapter} and \cs{frontmatter} but not
\cs{if@mainmatter}. In this case, you should use
\begin{verbatim}
\usepackage[report]{standardsectioning}
\end{verbatim}
instead of
\begin{verbatim}
\usepackage{standardsectioning}
\end{verbatim}
because otherwise the not defined \cs{if@mainmatter} will result in errors,
when using \cs{chapter}.
