% \begin{abstract}
%   Package \pkg*{floatrowbytocbasic} has started as hack module of the
%   \KOMAScript{} package \pkg*{scrhack} years ago to fix an issue when using
%   package \pkg{floatrow} with \KOMAScript~3.  This became necessary because
%   package \pkg{floatrow} still depends on an interface once proposed by the
%   \KOMAScript{} author, but which has long since failed to meet
%   requirements. Unfortunately, this problem could not be solved in dialog
%   with the author of \pkg{floatrow}. Although \pkg*{floatrowbytocbasic} still
%   loads the \pkg{floatrow} package, it then changes some internal commands to
%   use and optimally support the \KOMAScript{} package \pkg{tocbasic}. On the
%   one hand, the user interface of \pkg{floatrow} remains usable unchanged,
%   but at the same time the package benefits from many possibilities of
%   \pkg{tocbasic}.

\section{Why should I use this package instead of
  \texorpdfstring{\pkg{floatrow}}{floatrow} only if I use a \KOMAScript{}
  class or \KOMAScript{} package \texorpdfstring{\pkg{tocbasic}}{tocbasic}?}
\label{sec:whywithkomascript}

The main symptom of using a deprecated interface to \KOMAScript{} by package
\pkg{floatrow}, namely the use of \cs{float@listhead} and
\cs{float@addtolists}, are corresponding warnings when using one of the
\KOMAScript{} classes at the same time, for example:
\begin{verbatim}
  Class scrbook Warning: \float@addtolists detected!
  (scrbook)              Implementation of \float@addtolist became
  (scrbook)              deprecated in KOMA-Script v3.01 2008/11/14 and
  (scrbook)              has been replaced by several more flexible
  (scrbook)              features of package `tocbasic`.
  (scrbook)              Since Version 3.12 support for deprecated
  (scrbook)              \float@addtolist interface has been
  (scrbook)              restricted to only some of the KOMA-Script
  (scrbook)              features and been removed from others.
  (scrbook)              Loading of package `scrhack' may help to
  (scrbook)              avoid this warning, if you are using a
  (scrbook)              a package that still implements the
  (scrbook)              deprecated \float@addtolist interface.
\end{verbatim}
or
\begin{verbatim}
  Class scrbook Warning: \float@listhead detected!
  (scrbook)              Implementation of \float@listhead became
  (scrbook)              deprecated in KOMA-Script v3.01 2008/11/14 and
  (scrbook)              has been replaced by several more flexible
  (scrbook)              features of package `tocbasic`.
  (scrbook)              Maybe implementation of \float@listhead will
  (scrbook)              removed from KOMA-Script soon.
  (scrbook)              Loading of package `scrhack' may help to
  (scrbook)              avoid this warning, if you are using a
  (scrbook)              a package that still implements the
  (scrbook)              deprecated \float@listhead interface.
\end{verbatim}

If you know, that the issue is because of loading package \pkg{floatrow} you
can avoid it using \pkg{floatrowbytocbasic} as explained in
\autoref{sec:howtouse}.

\section{Why should I use this package instead of
  \texorpdfstring{\pkg{floatrow}}{floatrow} only if I don't use a
  \KOMAScript{} class or package?}
\label{sec:whywithoutkomascript}

Package \pkg{floatrow} does not check if a file extension or environment
already has been defined when using \cs{DeclareNewFloatType}. So several
definitions of float environments either with the same name or the same file
extension could happen by accident. Package \pkg*{floatrowbytocbasic} adds
test to avoid such issues. But it also allows to redefine an environment or
reuse a file extension, if you want. Alternatively you can force the
definition or do the definition only if needed. See description of
\cs{DeclareFloatType}, \cs{RedeclareFloatType} and \cs{ProvideFloatType} in
\autoref{sec:howtouse} for more information.

Package \pkg{tocbasic} provides several additional features, e.g.:
\begin{itemize}
\item automatic handling of language switching using \pkg{babel},
\item optional numbered heading for a list/table of contents,
\item optional adding an entry to the table of contents for a list/table of
  contents even if the heading is not numbered,
\item easy configuration of entries to a list/table of contents.
\end{itemize}
Several more features can be added by the class or other packages. See section
about \pkg*{tocbasic} in the \KOMAScript{} manual, either
\autocite{pkg:koma-script:manual:en} or \autocite{pkg:koma-script:manual:de}.

\section{How to use
  \texorpdfstring{\pkg*{floatrowbytocbasic}}{floatrowbytocbasic}}
\label{sec:howtouse}

In the document preamble of your document you just can replace
\begin{verbatim}
  \usepackage{floatrow}
\end{verbatim}
by
\begin{verbatim}
  \usepackage{floatrowbytocbasic}
\end{verbatim}
to load package \pkg*{floatrowbytocbasic}. This does still also load package
\pkg{floatrow} but additionally patches several commands of \pkg{floatrow} to
avoid the issues shown in \autoref{sec:whywithkomascript}.

If you want you can alternatively also load both packages explicitly, either
\pkg{floatrow} before \pkg{floatrowbytocbasic} or---if you
want---\pkg{floatrowbytocbasic} before \pkg{floatrow}. This is also useful, if
you use a package, that uses \pkg{floatrow} itself. In this case, you always
should load \pkg{floatrowbytocbasic} \emph{before} the package, that uses
\pkg{floatrow}. Otherwise it is very likely that for some new float
environments the enhancements of \pkg*{floatrowbytocbasic} will not be
used. Only if \pkg*{floatrowbytocbasic} is loaded before the first use of
\cs{DeclareNewFloatType} can it be ensured that the definition of the new
sliding environments is really done with the help of \pkg{tocbasic} and thus
its extended user interface is used.

When using a class that uses \pkg{floatrow}, the correct operation can be
ensured with
\begin{verbatim}
  \AddToHook{package/floatrow/after}{\RequirePackage{floatrowbytocbasic}}
\end{verbatim}
even before \cs{documentclass}. This requires at least \LaTeX{}
2020/10/01. For older versions of \LaTeX{} you can use
\begin{verbatim}
  \RequirePackage{scrlfile}
  \AfterPackage{floatrow}{\RequirePackage{floatrowbytocbasic}}
\end{verbatim}
also before \cs{documentclass}. This would require the \KOMAScript{} package
\pkg{scrlfile}\nocite{pkg:scrlfile}.

The user interface of \pkg*{floatrowbytocbasic} is the same as of
\pkg{floatrow}, see \autocite{pkg:floatrow:manual}. Following we document only
the differences.

\DescribeCommand{\DeclareNewFloatType}
\DescribeCommand{\ProvideFloatType}
\DescribeCommand{\RedeclareFloatType}
\DescribeCommand{\DeclareFloatType}
See \autocite[section~2]{pkg:floatrow:manual} for the basic usage of
\cs{DeclareNewFloatType}. The command takes two mandatory arguments. It is of
the form:
\begin{quote}
  \cs{DeclareNewFloatType}\marg{type}\marg{options}
\end{quote}
\pkg{floatrowbytocbasic} adds the registration of the file extension of the
new \meta{type} given either by option \opt{fileext} in the \meta{options} or
implicitly (see \autocite[section~4]{pkg:floatrow:manual}). The main problem
here is to decide what to do, if \meta{ext} already has been
registered. Package \pkg{floatrow} simply does not care for this case. It does
neither report an error nor a warning, but just redefine the float \meta{type}
and reuses the auxiliary file extension. Because of the ``\texttt{New}'' in
the name of the command, we have decided to report an error instead, but only
of the owner/category differs and therefore is not \texttt{float}. But we
also decided to define three new commands:
\begin{quote}\raggedright
  \cs{DeclareFloatType}\marg{type}\marg{options}\\
  \cs{ProvideFloatType}\marg{type}\marg{options}\\
  \cs{RedeclareFloatType}\marg{type}\marg{options}
\end{quote}
\cs{DeclareFloatTpye} also does not care for already existing \meta{type}
environment or already registered file extension. \cs{DeclareNewFloatType}
reports and error for an already existing \meta{type}
environment. \cs{ProvideFloatType} does not overwrite existing \meta{type}
environment or already registered file extensions for other
owners. \cs{RedeclareFloatType} does overwrite only already existing
\meta{type} environment with registered file extension. There are also cases
like defined \cs{\meta{type}} but not \cs{end\meta{type}} or not defined
environment \meta{type} but registered file extension. But there are no
special commands to handle these. If users need to take care for these cases,
they can test for definition using the \LaTeX{} kernel macro \cs{@ifundefined}
and the \pkg{tocbasic} command \cs{Ifattoclist}, described in the
\KOMAScript{} user manuals \autocite{pkg:koma-script:manual:en}
resp. \autocite{pkg:koma-script:manual:de}.

% \section{Implementation}
%
% \pkg{floatrowbytocbasic} depend on \KOMAScript{} package \pkg{tocbasic}. So
% we load it already before everything else. We use this package also to
% require at least \KOMAScript{} 3.41, which is one version before the
% intended spin-off.
%    \begin{macrocode}
\RequirePackage{tocbasic}[2023/07/07]
%    \end{macrocode}
%
% We also load package \pkg{floatrow}, because we reuse most of the code:
%    \begin{macrocode}
\RequirePackage{floatrow}
%    \end{macrocode}
%
% As often as possible, we do not redefine macors of \pkg{floatrow}, but patch
% them using \pkg{xpatch}\nocite{pkg:xpatch}:
%    \begin{macrocode}
\RequirePackage{xpatch}
%    \end{macrocode}
%
% We also use some \LaTeX3 functions. So if the \LaTeX{} kernel is
% too old, we require \pkg{expl3}:
%    \begin{macrocode}
\@ifundefined{ExplSyntaxOn}{%
  \RequirePackage{expl3}%
}{}
%    \end{macrocode}
%
% \begin{command}{\DeclareFloatType}
% Basicly \cs{DeclareFloatType} is \cs{DeclareNewFloatType} of
% \pkg{floatrow}:
%    \begin{macrocode}
\@ifundefined{NewCommandCopy}{\let\DeclareFloatType\DeclareNewFloatType}{%
  \NewCommandCopy\DeclareFloatType\DeclareNewFloatType
}
%    \end{macrocode}
% But we also have to take care, that a not yet registered file extension has
% to be registered.
% \begin{description}
% \item[Note:] We do not need to setup feature \texttt{chapteratlist}, because
%   classes like the \KOMAScript{} classes should use
%\begin{verbatim}
%  \AtAddToTocList[float]{\setuptoc{\@currext}{chapteratlist}}
%\end{verbatim}
%   to implement such features.
