+# Abstract
+
+For several years
+[KOMA-Script](https://www.sourceforge.net/project/koma-script) provided a
+package `scrhack`, that has been made not only to improve the compatibility of
+third-party packages with KOMA-Script classes, but also to generally improve
+third-party packages. The package consisted not only in the package file
+`scrhack.sty` but also in several so called hacks as separate files with
+extension `.hak`. In the course of splitting off former KOMA-Script packages
+from the KOMA-Script collection, it was decided to create independent packages
+from the individual hacks. These new independent packages then serve as
+replacements for the original packages they were intended to improve. Package
+`floatrowbytocbasic` is such an enhancement package. It provides additional
+features of using package [`tocbasic`](https://ctan.org/pkg/tocbasic) by
+patching package [`floatrow`](https://ctan.org/pkg/floatrow).
+
+# Installation for Users
+
+If you are a user, you should wait until the package has been added to your
+preferred TeX distribution. Then you can use the package manager of your TeX
+distribution to install the package.
+
+# Unpacking for Distributors
+
+Distributors should download [the distribution from
+CTAN](https://www.ctan.org/pkg/floatrowbytocbasic). This consists in:
+
+* `floatrowbytocbasic.dtx`
+* `README.md`
+* `LICENSE.md`
+* `floatrowbytocbasic.pdf`
+
+If distributors also want to distribute `floatrowbytocbasic.sty`, they can
+unpack it using
+
+    tex floatrowbytocbasic.dtx
+	
+Note, that you have to use `tex` not `latex`, `pdflatex`, `xelatex` or
+`lualatex`!
+
+Note also, that a legal distribution consists at least in:
+
+* `floatrowbytocbasic.dtx`
+* `README.md`
+
+The following files are optionally, but must not be distributed without the
+previous ones:
+
+* `LICENSE.md`
+* `floatrowbytocbasic.sty`
+* `floatrowbytocbasic.pdf`
+
+# Unpacking and Installation for Developers
+
+Developers who want the current developer version of the code to be installed
+for testing, should clone [the `third-party-enhancements`
+repository](https://github.com/komascript/third-party-enhancements), e.g.,
+using
+
+	git clone https://github.com/komascript/third-party-enhancements.git
+
+You can than either unpack and install all the third-party enhancements using:
+
+	l3build install --full
+	
+from within the main directory of the cloned respository. For installation of
+`floatrowbytocbasic` only run the same command from within the
+`floatrowbytocbasic` subdirectory. For installation without the manual omit
+option `--full`, but this is not recommended for developers.
+
+# How to get the Manual
+
+After installation you should get the user manual using:
+
+    texdoc floatrowbytocbasic
+	
+See the manual of your TeX distribution for more information. 
+
+Developers or distributors can also build the manual from the source using:
+
+	l3build doc
+	
+# How to Contribute
+
+To become a contributor, e.g., do heavy testing. If you find an issue, please
+report it using [the issue
+tracker](https://github.com/komascript/third-party-enhancements/issues). You
+can also become a developer and, e.g., make new test files to the
+packages. See the [`l3build`](https://ctan.org/pkg/l3build) manual for more
+information about tests. If you've created a new test and think that it would
+be useful. Please either do a pull request or [add a new
+issue](https://github.com/komascript/third-party-enhancements/issues/new/choose)
+and include your test file.
+
+Another kind of contribution would be to contact an author of one of the
+third-party packages and convince her or him to integrate the code of the
+corresponding enhancement package from this project into her or his package.
+
+# How to Report Issues
+
+If you think you have found a bug (or another kind of issue) using
+`floatrowbytocbasic` you should use [the issue
+tracker](https://github.com/komascript/third-party-enhancements/issues). Please
+first search for similar issues already reported and maybe also already fixed
+and closed. Maybe the replies to such a similar report would help you too.
+
+If your issue is new, you should report it also using [the issue
+tracker](https://github.com/komascript/third-party-enhancements/issues). Please
+be kind, not only when writing the report but also when reading replies and
+commenting or answering. And please always add a minimal working example and
+usually the relevant parts of the `log`-file to your report. Please use the
+[markdown for
+code](https://docs.github.com/en/get-started/writing-on-github/working-with-advanced-formatting/creating-and-highlighting-code-blocks)
+to add such files into the text of your report. The correct language
+identifier for LaTeX code would be `latex`. For `log`-files you won't need any
+language identifier. Usually you should not use attachments for code or
+`log`-files unless you've been asked to do so. And please note, reports should
+always be self-containing. External links often break and so the report become
+useles.
+
+# How to Say Thank You for my Work
+
+Hey, I'm doing this as a hobby. So no need to say thank you. But I'm a vain
+fop, so I'm certainly up for a quick thank you by email. On komascript.de you
+can find an [explanation of my wishes](https://komascript.de/wunschliste) if
+you want to give more. If you don't understand German, just click to links at
+that page.

+% \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{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}

+% \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.

+% \begin{description}
