\section{Library \mylib{xparse}}\label{sec:xparse}%
\tcbset{external/prefix=external/xparse_}%
The library is loaded by a package option or inside the preamble by:
\begin{dispListing}
\tcbuselibrary{xparse}
\end{dispListing}
This also loads the package |xparse| \cite{latexproject:2013a}.

The purpose of this library is to give comfortable access to the
powerful document command production with |xparse| for |tcolorbox|.
See the |xparse| package documentation \cite{latexproject:2013a}
for details about the argument \meta{specification} used in this section.

%\subsection{Producing Document Commands With \texttt{xparse}}


\subsection{Option Keys}\label{subsec:xparse_options}

\begin{docTcbKey}{verbatim}{}{style, no value}
  Sets options for a \textit{verbatim} style \refCom{tcbox}.
  Since the indented boxes may contain only very few words, the
  dimensions are made smaller and \refKey{/tcb/nobeforeafter}
  and \refKey{/tcb/tcbox raise base} are set.
\begin{dispExample*}{sbs,lefthand ratio=0.6}
\DeclareTotalTCBox{\myverb}{ v }{verbatim,
  colframe=red!75!black,colupper=blue}{#1}

\myverb{\textbf} is a \myverb{\LaTeX} command.
\end{dispExample*}
\end{docTcbKey}


\begin{docTcbKey}{IfNoValueTF}{=\marg{argument}\marg{true options}\marg{false options}}{no default}
  Wraps the |\IfNoValueTF| command of |xparse| for option setting.
  If the \meta{argument} has no value, the \meta{true options} are set.
  Otherwise, the \meta{false options} are set.
\begin{dispExample}
\DeclareTColorBox{mybox}{ o }{colframe=red!75!black,
  IfNoValueTF={#1}{colback=red!5!white}{enhanced,interior style image=#1}}

\begin{mybox}
This is a tcolorbox.
\end{mybox}

\begin{mybox}[goldshade.png]
This is a tcolorbox.
\end{mybox}
\end{dispExample}
\end{docTcbKey}

\clearpage
\begin{docTcbKey}{IfValueTF}{=\marg{argument}\marg{true options}\marg{false options}}{no default}
  Wraps the |\IfValueTF| command of |xparse| for option setting.
  If the \meta{argument} has a value, the \meta{true options} are set.
  Otherwise, the \meta{false options} are set.
\begin{dispExample}
\DeclareTColorBox{mybox}{ o }{colframe=red!75!black,colback=red!5!white,
  IfValueTF={#1}{title={\flqq #1\frqq},fonttitle=\bfseries}{}}

\begin{mybox}
This is a tcolorbox.
\end{mybox}

\begin{mybox}[My title]
This is a tcolorbox.
\end{mybox}
\end{dispExample}
\end{docTcbKey}

\begin{docTcbKey}{IfBooleanTF}{=\marg{argument}\marg{true options}\marg{false options}}{no default}
  Wraps the |\IfBooleanTF| command of |xparse| for option setting.
  If the \meta{argument} is |\BooleanTue|, the \meta{true options} are set.
  If the \meta{argument} is |\BooleanFalse|, the \meta{false options} are set.

\begin{dispExample}
\DeclareTColorBox{mybox}{ s }{colframe=red!75!black,
  IfBooleanTF={#1}{colback=yellow!50!red}{colback=red!5!white}}

\begin{mybox}
This is a tcolorbox.
\end{mybox}

\begin{mybox}*
This is a tcolorbox.
\end{mybox}

\subsection{Producing \texttt{tcolorbox} Environments and Commands}\label{subsec:xparse_tcolorbox}

\begin{docCommand}{DeclareTColorBox}{\oarg{init options}\marg{name}\marg{specification}\marg{options}}
  Creates a new environment \meta{name} based on \refEnv{tcolorbox}.\\
  Basically, |\DeclareTColorBox| operates like |\DeclareDocumentEnvironment|. This means,
  the new environment \meta{name} is constructed with the given argument \meta{specification}.
  The \meta{options} are given to the underlying \refEnv{tcolorbox}.\\
  Note that \refKey{/tcb/savedelimiter} is set to the given \meta{name}
  automatically.\\
  The \meta{init options} allow setting up automatic numbering,
  see Section \ref{sec:initkeys} from page \pageref{sec:initkeys}.\\
  The new environment is always created, irrespective of an already existing
  environment with the same name.

\begin{dispExample}
% counter from previous example
\DeclareTColorBox[use counter from=pabox]{mybox}{ O{red} m d"" O{} }
  {enhanced,colframe=#1!75!black,colback=#1!5!white,
   fonttitle=\bfseries,title={\thetcbcounter~#2},
   IfValueTF={#3}{watermark text={#3}}{},#4}

\begin{mybox}{My title}
This is a tcolorbox.
\end{mybox}

\begin{mybox}[blue]{My title}
This is a tcolorbox.
\end{mybox}

\begin{mybox}[green]{My title}"My Watermark"
This is a tcolorbox.
\end{mybox}

\begin{mybox}[yellow]{My title}[colbacktitle=yellow!50!white,coltitle=black]

\clearpage

\begin{docCommand}{DeclareTotalTCBox}{\oarg{init options}\brackets{\texttt{\textbackslash}\meta{name}}\marg{specification}\marg{options}\marg{content}}
  Creates a new command \texttt{\textbackslash}\meta{name} based on \refCom{tcbox}.
  In contrast to \refCom{DeclareTCBox}, also the \meta{content} of the |tcbox| is specified.\\
  Basically, |\DeclareTotalTCBox| operates like |\DeclareDocumentCommand|. This means,
  the new command \texttt{\textbackslash}\meta{name} is constructed with the given argument \meta{specification}.
  The \meta{options} are given to the underlying \refCom{tcbox} which is filled with
  the specified \meta{content}.\\
  Note that \refKey{/tcb/savedelimiter} is set to the given \meta{name}
  automatically.\\
  The \meta{init options} allow setting up automatic numbering,
  see Section \ref{sec:initkeys} from page \pageref{sec:initkeys}.\\
  The new command is always created, irrespective of an already existing
  command with the same name.

\begin{dispExample}
\DeclareTotalTCBox{\myverb}{ O{red} v O{} }
{ fontupper=\ttfamily,nobeforeafter,tcbox raise base,arc=0pt,outer arc=0pt,
  top=0pt,bottom=0pt,left=0mm,right=0mm,
  leftrule=0pt,rightrule=0pt,toprule=0.3mm,bottomrule=0.3mm,boxsep=0.5mm,
  colback=#1!10!white,colframe=#1!50!black,#3}{#2}

To set a word \textbf{bold} in \myverb{\LaTeX}, use
\myverb[green]{\textbf{bold}}. Alternatively, write
\myverb[yellow]{{\bfseries bold}}.
In \myverb[blue]{\LaTeX}[enhanced,fuzzy halo], other font settings are
done in the same way, e.\,g. \myverb{\textit}, \myverb{\itshape}\\
or \myverb[brown]{\texttt}, \myverb[brown]{\ttfamily}.
\end{dispExample}

The next example uses |\lstinline| from the |listings| package to
typeset the verbatim content.

\begin{dispExample}
% \usepackage{listings} or \tcbuselibrary{listings}
\DeclareTotalTCBox{\commandbox}{ s v }
{verbatim,colupper=white,colback=black!75!white,colframe=black}
{\IfBooleanTF{#1}{\textcolor{red}{\ttfamily\bfseries > }}{}%
  \lstinline[language=command.com,keywordstyle=\color{blue!35!white}\bfseries]^#2^}

\commandbox*{cd "My Documents"} changes to directory \commandbox{My Documents}.

\commandbox*{dir /A} lists the directory content.

\commandbox*{copy example.txt d:\target} copies \commandbox{example.txt} to
  \commandbox{d:\target}.
\end{dispExample}
\end{docCommand}

\clearpage
\begin{docCommand}{NewTotalTCBox}{\oarg{init options}\brackets{\texttt{\textbackslash}\meta{name}}\marg{specification}\marg{options}\marg{content}}
  Operates like \refCom{DeclareTotalTCBox}, but based on |\NewDocumentCommand| instead of |\DeclareDocumentCommand|.
  An error is issued if \texttt{\textbackslash}\meta{name} has already been defined.
\end{docCommand}

\begin{docCommand}{RenewTotalTCBox}{\oarg{init options}\brackets{\texttt{\textbackslash}\meta{name}}\marg{specification}\marg{options}\marg{content}}
  Operates like \refCom{DeclareTotalTCBox}, but based on |\RenewDocumentCommand| instead of |\DeclareDocumentCommand|.
  An existing command is redefined.
\end{docCommand}

\begin{docCommand}{ProvideTotalTCBox}{\oarg{init options}\brackets{\texttt{\textbackslash}\meta{name}}\marg{specification}\marg{options}\marg{content}}
  Operates like \refCom{DeclareTotalTCBox}, but based on |\ProvideDocumentCommand| instead of |\DeclareDocumentCommand|.
  The command \texttt{\textbackslash}\meta{name} is only created if it is not already defined.
\end{docCommand}


\begin{docCommand}{tcboxverb}{\oarg{options}\marg{verbatim box content}}
  Creates a colored box based on \refCom{tcbox} which is fitted to the width of the given
  \meta{verbatim box content}.
  The underlying \refCom{tcbox} is styled with
  \refKey{/tcb/verbatim} plus the given \meta{options}.
  The difference to \refCom{tcbox} is that the \meta{verbatim box content} is
  interpreted \textit{verbatim}. Therefore, |\tcboxverb| acts similar to |\verb|.

\begin{dispExample}
\tcboxverb{\LaTeX}, \tcboxverb[colback=blue!10!white,colupper=blue]{\LaTeX},
\tcboxverb[blank,fuzzy halo]{\LaTeX}, \tcboxverb[beamer]{\LaTeX},
\tcboxverb[enhanced,skin=enhancedmiddle jigsaw,colframe=red]{\LaTeX}.
