\section{Library \mylib{documentation}}\label{sec:documentation}%
\tcbset{external/prefix=external/documentation_}%
This library has the single purpose to support \LaTeX\ package documentations
like this one. Actually, the visual nature follows the approach from
Till Tantau's \refPkg{pgf} \cite{tantau:tikz_and_pgf} documentation.
Typically, this library is assumed to be used in conjunction with the
class \refPkg{ltxdoc} or alike.
Denis Bitouz\'e, Muzimuzhi, and many others provided very valuable input for this library.

The library is loaded by a package option or inside the preamble by:
\begin{dispListing}
  \tcbuselibrary{documentation}
\end{dispListing}
This also loads
the library \mylib{skins}, see \Vref{sec:skins},
the library \mylib{raster}, see \Vref{sec:raster},
the library \mylib{listings}, see \Vref{sec:listings},
and a bunch of packages, namely
\refPkg{makeidx}, \refPkg{marginnote}, \refPkg{refcount}, and \refPkg{hyperref}.
The packages \refPkg{pifont} and \refPkg{marvosym} should be installed for some symbols, but
need not to be loaded.

\begin{marker}
The package \refPkg{makeidx} is loaded only, if \docAuxCommand*{printindex} is
\emph{not} already defined. Therefore, one can include an alternative to \refPkg{makeidx} like
\refPkg{imakeidx} \emph{before} the library |documentation| is used.
\end{marker}
\begin{marker}
The package \refPkg{marginnote} is loaded only, if \docAuxCommand*{marginnote} is
\emph{not} already defined.
\end{marker}
\begin{marker}
In contrast to other |tcolorbox| options, the option
settings for \mylib{documentation} are typically not
getting reset by \refKey{/tcb/reset}, i.e. they keep their
values for embedded boxes.
\end{marker}
\begin{marker}
In combination with DocStrip, \refKey{/tcb/verbatim ignore percent} may be helpful.
\end{marker}

For UTF-8 support load (ignore this when using Xe\LaTeX):
\begin{dispListing}
  \tcbuselibrary{listingsutf8,documentation}
\end{dispListing}

For \refPkg{minted} \cite{poore:minted} support, load:
\begin{dispListing}
  \tcbuselibrary{documentation,minted}
  \tcbset{listing engine=minted}
\end{dispListing}

\subsection{Entry Content Option Keys}


\begin{docTcbKey}[][doc new={2020-04-22}]{doc name}{=\meta{name}}{no default, initially empty}
  Sets the \meta{name} of the entry to document, i.e. the \meta{name} of the
  command, environment, key, etc. For \refEnv{docCommand}, \refEnv{docEnvironment}, etc.
  the \meta{name} is set by a mandatory parameter, but can also be set
  by \refKey{/tcb/doc name}.
  \refKey{/tcb/doc name} also sets \meta{name} to
  \refKey{/tcb/doc label}, \refKey{/tcb/doc index},
  and \refKey{/tcb/doc sort index}.
\begin{dispExample}
\begin{docCommands}[
    doc no index,  %  no index entries for this example
    doc name      = bfseries,
  ] {}
  Font setting to bold face.
\end{docCommands}
\end{dispExample}
\end{docTcbKey}


\begin{docTcbKey}[][doc new={2020-04-22}]{doc parameter}{=\meta{parameters}}{no default, initially empty}
  Sets the \meta{parameters} of the entry to document, i.e. the \meta{parameters} of the
  command, environment, key, etc. For \refEnv{docCommand}, \refEnv{docEnvironment}, etc.
  the \meta{parameters} is set by a mandatory option, but can also be set
  by \refKey{/tcb/doc parameter}.
\begin{dispExample}
\begin{docCommands}[
    doc no index,  %  no index entries for this example
    doc name      = textbf,
    doc parameter = \marg{text},
  ] {}
  Sets \meta{text} in bold face.
\end{docCommands}
\end{dispExample}
\end{docTcbKey}



\begin{docTcbKey}[][doc new={2020-04-22}]{doc keypath}{=\meta{key path}}{no default, initially empty}
  Sets the \meta{key path} of the key to document. For \refEnv{docKey}
  and \refEnv{docKey*} the \meta{key path}  is set by a specialized option,
  but can also be set by \refKey{/tcb/doc keypath}.
\begin{dispExample}
\begin{docKeys}[
    doc no index,  %  no index entries for this example
    doc keypath     = tikz,
    doc name        = fill,
    doc parameter   = \colOpt{=\meta{color}},
    doc description = default is scope's color setting,
  ] {}
  This option causes the path to be filled.
\end{docKeys}
\end{dispExample}
\end{docTcbKey}

\begin{docTcbKeys}[
    doc new         = {2023-12-01},
    doc name        = doc key prefix,
    doc parameter   = {=\meta{key prefix}},
    doc description = {no default, initially |/|},
  ]{}
  Sets the \meta{key prefix} (root path) of the key to document.
  This prefix is prepended to \refKey{/tcb/doc keypath}, if
  \refKey{/tcb/doc keypath} is not empty.
  The default |/| setting is intended for |pgfkeys|.
  For |l3keys|, setting \refKey{/tcb/doc key prefix} to be empty is more
  appropriate, since their path starts with a module name without |/|.
\begin{dispExample}
\begin{docKeys}[
    doc no index,  %  no index entries for this example
    doc key prefix  = ,
    doc keypath     = tcobox,% module name
    doc name        = my_l3_key,
    doc parameter   = {=\meta{some value}},

  ]{
    {
      doc name = index key formatter,
    },
    {
      doc name = index keys formatter,
    }
  }
Sets \meta{macro} as formatter for the text given by
\refKey{/tcb/doclang/key} or
\refKey{/tcb/doclang/keys} inside the index.
The \meta{macro} has to take one mandatory
argument (the language text).
The intended purpose is to differentiate between different sorts of
keys, if necessary, e.g.\ between |pgfkeys| and |l3keys|.
If these options are used without value, the formatters are reset to
their standard behavior.

\begin{dispExample}
% See index of this documentation to recognize the effect
\newcommand{\myFormatPgfkeysIndex}[1]{#1 (\textsf{pgfkeys})}
\newcommand{\myFormatExplkeysIndex}[1]{#1 (\textsf{l3keys})}

\tcbmakedocSubKey[

\begin{docTcbKey}{doc description}{=\meta{description}}{no default, initially empty}
  Sets a (short!) additional \meta{description} for
  \refEnv{docCommand}, \refEnv{docEnvironment}, or \refEnv{docPathOperation}.
  Such a description is
  mandatory for \refEnv{docKey}.
\begin{dispExample}
\begin{docCommand*}[doc description=my description]{myCommandF}{\marg{argument}}
  This is the documentation of \refCom{myCommandF} which takes one \meta{argument}.
  \refCom{myCommandF} does some funny things with its \meta{argument}.
\end{docCommand*}
\end{dispExample}
\begin{marker}
Note that the description \meta{text} may overlap with the text on the left
hand side if too long. Linebreaks can be used inside the \meta{text}.
\end{marker}
\end{docTcbKey}


\begin{docTcbKey}[][doc new={2019-09-18}]{doc label}{=\meta{text}}{no default, initially unset}
  If used inside the option list of \refEnv{docCommand}, \refEnv{docEnvironment},
  \refEnv{docKey}, etc, then \meta{text} is used
  for labeling instead of the name of the definition.
\begin{dispExample}
\begin{docPathOperation*}[doc label=pathline]{-{}-}{\meta{coordinate or cycle}}
  This is the documentation of \refPathOperation{pathline}.
\end{docPathOperation*}
\end{dispExample}

  If used inside the option list of \refEnv{docCommand}, \refEnv{docEnvironment},
  \refEnv{docKey}, etc, then \meta{text} is used
  for the index instead of the name of the definition.
\begin{dispExample}
\begin{docPathOperation}[doc index=foo path (horizontal then vertical),
    doc label=pathline2]{-\textbar}{\meta{coordinate or cycle}}

\subsection{General Customization Option Keys}

\begin{docTcbKey}[][doc updated=2015-03-16]{docexample}{}{style, no value}
  Sets the style for \refEnv{dispExample} and \refEnv{dispListing}
  with the colors |ExampleBack| and |ExampleFrame|.
  To change the appearance of the examples, this style can be
  redefined.
\begin{dispListing}
% Predefined style:
\tcbset{
  docexample/.style={colframe=ExampleFrame,colback=ExampleBack,
    before skip=\medskipamount,after skip=\medskipamount,

\begin{docTcbKey}{documentation listing options}{=\meta{key list}}{no default,\\\hspace*{\fill} initially |style=tcbdocumentation|}
  Sets the options from the package \refPkg{listings} \cite{hoffmann:listings}.
  They are used inside \refEnv{dispExample} and \refEnv{dispListing} to typeset
  the listings. Note that this is not identical to the key
  \refKey{/tcb/listing options} which is used for \enquote{normal} listings.\\
  Used for \refKey{/tcb/listing engine}|=listings| only.
\end{docTcbKey}

\begin{docTcbKey}{documentation listing style}{=\meta{listing style}}{no default, initially |tcbdocumentation|}
  Abbreviation for |documentation listing options={style=...}|.
  This key sets a \meta{style}
  for the \refPkg{listings} package, see \cite{hoffmann:listings}.
  Note that this is not identical to the key
  \refKey{/tcb/listing style} which is used for \enquote{normal} listings.\\
  Used for \refKey{/tcb/listing engine}|=listings| only.
\end{docTcbKey}

\begin{docTcbKey}{documentation minted options}{=\meta{key list}}{no default,\\\hspace*{\fill} initially |tabsize=2,fontsize=\textbackslash small|}

\end{docTcbKey}

\begin{docTcbKey}{documentation minted style}{=\meta{key list}}{no default, initially unset}
  Sets a \meta{style} known to |Pygments| \cite{pygments:web} for
  the package \refPkg{minted} \cite{poore:minted}, if used.
  Note that this is not identical to the key
  \refKey{/tcb/minted style} which is used for \enquote{normal} listings.\\
  Used for \refKey{/tcb/listing engine}|=minted| only.
\end{docTcbKey}

\begin{docTcbKey}[][doc new=2017-04-24]{documentation minted language}{=\meta{programming language}}{no default, initially |latex|}
  Sets a \meta{programming language} known to |Pygments| \cite{pygments:web}
  for the package \refPkg{minted} \cite{poore:minted}, if used.

  \refKey{/tcb/minted language} which is used for \enquote{normal} listings.\\
  Used for \refKey{/tcb/listing engine}|=minted| only.
\end{docTcbKey}


\begin{docTcbKey}[][doc new=2017-04-25]{keywords bold}{\colOpt{=true\textbar false}}{default |true|, initially |true|}
  Keyword used in \refEnv{docEnvironment}, \refEnv{docCommand}, etc. are printed
  boldface (or not). Since the typewriter font is used, the effect may be
  invisible with Computer Modern fonts or similar which do not
  have a bold variant. Note that references to keywords are not printed boldface at all.
\begin{dispExample*}{sidebyside}
\LARGE
\docAuxCommand{fooaux}, \refCom{tcbset}

\tcbset{keywords bold=false}
\docAuxCommand{fooaux}, \refCom{tcbset}

      doc parameter   = \colOpt{=\meta{macro}},
      doc description = {no default, initially \texttt{\textbackslash textsuperscript}},
    }
  }
Sets \meta{macro} as formatter for page references like the
reference to \refEnv{tcolorbox}.
The default setting puts the page reference in a |\textsuperscript|.
It may be changed to |\fakesuperscript| to cope with superiors problems
in combination with the \refPkg{realscripts} package or just otherwise for user customization.
\end{docTcbKeys}



\begin{docTcbKey}[][doc new=2015-01-09]{index command}{=\meta{macro}}{no default, initially \cs{index}}
  Replaces the internally used \cs{index} macro by the given \meta{macro}.
  The \meta{macro} has to take one mandatory argument like \cs{index}.
  This option is mutually exclusive with \refKey{/tcb/index command name}.
\begin{dispListing}
\tcbset{index command=\myindexcommand}
\end{dispListing}
\end{docTcbKey}


\begin{docTcbKey}[][doc new=2015-01-09]{index command name}{=\meta{name}}{no default, initially unset}
  Replaces the internally used \cs{index} macro by
  \mbox{\cs{index}\texttt{[\meta{name}]}}, i.e.\ 
  \mbox{\cs{index}\texttt{\textbraceleft\ldots\textbraceright}} is replaced by
  \mbox{\cs{index}\texttt{[\meta{name}]\textbraceleft\ldots\textbraceright}}.
  This option is intended to be used with |imakeidx| and is
  mutually exclusive with \refKey{/tcb/index command}.
\begin{dispListing}
\tcbset{index command name=mydoc}
\end{dispListing}
\end{docTcbKey}



\begin{docTcbKey}{index format}{=\meta{format}}{no default, initially |pgf|}
  Determines the basic \meta{format} of the generated index.
  Feasible values are:
  \begin{itemize}
  \item\docValue{pgfsection}: The index is formatted like in the |pgf| documentation (as a section).
  \item\docValue{pgfchapter}: The index is formatted like in the |pgf| documentation (as a chapter).
  \item\docValue{pgf}: Alias for |pgfsection|.
  \item\docValue{doc}: The index is assumed to be formatted by |doc| or |ltxdoc|. The usage of |makeindex|
    with |-s gind.ist| is assumed. The package \refPkg{hypdoc} has to be loaded
    \emph{before} |tcolorbox|. Only a limited set of customizations will
    work! This option cannot be unset when used!
  \item\docValue{off}: The index is not formatted by |tcolorbox|. Use this, if
    the index is formatted by other package like \refPkg{imakeidx}.
  \end{itemize}
\end{docTcbKey}


\begin{docTcbKey}{index actual}{=\meta{character}}{no default, initially |@|}
  Sets the character for \enquote{actual} in automatic indexing.

\end{docTcbKey}

\begin{docTcbKey}{index default settings}{}{style, no value}
  Sets the |makeindex| default values for
  \refKey{/tcb/index actual},
  \refKey{/tcb/index quote}, and
  \refKey{/tcb/index level}.
\end{docTcbKey}

\enlargethispage*{1cm}

\begin{docTcbKey}{index german settings}{}{style, no value}
  Sets the |makeindex| values recommended for German language texts.
  This is identical to setting the following:
\begin{dispListing}
\tcbset{index actual={=},index quote={!},index level={&gt;}}
\end{dispListing}
\end{docTcbKey}

\begin{docTcbKey}{index annotate}{\colOpt{=true\textbar false}}{default |true|, initially |true|}
  If set to |true|, the index entries are annotated with short descriptions
  given by \refKey{/tcb/doclang/environment}, \refKey{/tcb/doclang/key},
  and others.

  }
  If set to |true|, an additional index grouping is created where entries
  are gathered, e.g. \refKey{/tcb/index gather counters} creates an index
  entry `Colors', see \refKey{/tcb/doclang/colors}, which gets all colors
  as sub entries.
