+This is version 1.5a of the skdoc document class. It is designed to
+generate both documentation and derivative files using only LaTeX,
+i.e. without using docstrip and ins/dtx files.
+
+The following files are enclosed.
+
+ README - This file
+ Makefile - GNU Makefile for making the package and documentation
+ skdoc.dtx - LaTeX source code of the package
+ skdoc.pdf - PDF version of the documentation
+
+Installation notes:
+The easiest way to install this package, assuming you have obtained the
+source code from Github or CTAN, is to simply run `make install`. This
+will generate package code and documentation, install it into TEXMFHOME
+and run `mktexlsr`. If you wish to compile the package but not install
+it, run `make all` instead. If you insist on doing it manually, remember
+to run `tex` to generate the code, and `pdflatex` (or `latex`, if you
+don't fancy PDFs) to generate the documentation.

+% \maketitle
+%
+% \begin{abstract}
+% The \thepkg{} class provides macros to document the functionality
+% and implementation of \LaTeX\ packages and document classes. It is
+% loosely based on the \pkg{ydoc} and \pkg{ltxdoc} classes, but has
+% a number of incompatible differences.
+%
+% The class defines a \env{MacroCode} environment which substitutes
+% the usual \pkg{docstrip} method of installing packages. It has the
+% ability to generate both documentation and code in a single run of
+% a single file.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Introduction}
+% This document class, inspired by a question on the \TeX\ Stack
+% Exchange\footcite{Lazarides12}, aims to provide an alternative to
+% the standard \pkg{docstrip} method of literate programming for
+% \LaTeX\ packages. It also aims to provide a more modern, appealing
+% style for \LaTeX\ package documentation.
+%
+% In order to achieve this, it builds upon already existing features
+% of the \pkg{expl3}, \pkg{verbatim} and \pkg{ydoc} packages as well
+% as the KOMA-script document classes.
+%
+% So far it is mainly intended to be an experiment to explore a less
+% cumbersome way of writing \LaTeX\ packages, and as such I give no
+% guarantee that this package will continue to exist in a working
+% state (\emph{i.e.} future users may not be able to extract code from
+% package documentation based on \thepkg) or that its public API
+% (commands and environments described by this documentation; consider
+% undocumented macros part of a private API) will be stable.
+%
+% The documentation of \thepkg\ is in fact typeset using the class
+% itself. It does not, however, make use of the main feature of this
+% class (the \env{MacroCode} environment), because bootstrapping the
+% class to generate itself is more complicated than it is useful.
+%
+% \section{Documentation}
+% Since \thepkg\ is based on \pkg{ydoc} many of the macros and
+% environment present in that package are also available in \thepkg,
+% in a possibly redefined incanation. However, any macros or
+% environment present in \pkg{ydoc} but not described in this
+% documentation should be considered part of the private API of
+% \thepkg. In the future, the removal of the \pkg{ydoc} dependency
+% may result in such macros being unavailable, and at present changes
+% made by \thepkg\ may break such macros without notice.
+%
+% \subsection{Options}
+% \Option{load}\WithValues{\meta{package}}\AndDefault{\cs{jobname}}
+% \label{ssec:options:load} The \opt{load}
+% option declares that if the package specified exists, it should
+% be loaded. This is intended to load any package provided in the
+% implementation, but requires that the documentation provides
+% stub variants of the macros used in the documentation so that
+% \LaTeX\ still completes its first run.
+%
+% \Option{highlight}\WithValues{true,false}\AndDefault{true}
+% \label{ssec:option:highlight}
+% The \opt{highlight} option enables or disabled syntax highlighting
+% of the implementation code. Highlighting is performed using
+% \pkg{minted}, and falls back to no highlighting if there is no
+% \cs{write18} access, if \pkg{minted} is unavailable or if the
+% \texttt{pygmentize} binary can't be found.
+% \Notice{On non-unix platforms, the test for \texttt{pygmentize}
+% will likely fail. Therefore, syntax highlighting is not supported
+% on such platforms.}
+%
+% Generally, there should be no reason to disable syntax highlighting
+% unless the documentation describes a very large package, and the
+% repeated calls to \texttt{pygmentize} take too long.
+%
+% \Option{babel}
+% The \opt{babel} option allows you to specify what languages are loaded
+% by the \pkg{babel} package. It is a key-value option, and its content
+% is passed as options to the \pkg{babel} \cs*{usepackage} declaration.
+%
+% \subsection{General macros}
+% The document class defines a number of general macros intended for
+% use in parts of the document not strictly considered
+% \enquote{documentation} or \enquote{implementation}, in addition to
+% being used in those parts. These \enquote{general} macros include
+% macros that define metadata, generate the title page, typeset
+% notices or warnings and those that refer to macros, environments,
+% packages and such.
+%
+% \subsubsection{Metadata}
+% Several macros for defining metadata (\emph{i.e.} information about
+% the package and its documentation) are made available. These mostly
+% set an internal variable which is used to typeset the title page,
+% and to insert PDF metadata whenever \hologo{pdfLaTeX} is used to
+% generate the documentation.
+%
+% \DescribeMacro\package['ctan='<identifier>',vcs='<url>]{<package name>}
+% The \cs{package} macro defines the package name used by \cs{thepkg},
+% \cs{maketitle} and similar macros. It also calls \cs{title} to set
+% a sensible default title based on the package name. The optional
+% key-value argument takes two keys: \texttt{ctan} and \texttt{vcs}.
+% The first one accepts an optional value \meta{identifier}, which
+% should be the identifier the package has on CTAN (the default is
+% \cs{jobname}), while the other takes a mandatory argument \meta{url}
+% specifying the URL of a VCS repository where development versions
+% of the package are available. The two optional keys imply calls to
+% the \cs{ctan} and \cs{repository} macros, respectively.
+%
+% \DescribeMacro\version{<version>}
+% Sets the version number of the package the documentation describes.
+% Here, \meta{version} should not include the initial \enquote{v},
+% \emph{i.e.} the argument should be the same as that given to
+% \emph{e.g.} the \LaTeX3 \cs{ProvidesExplPackage} or the standard
+% \pkg{ltxdoc} \cs{changes}.
+%
+% \DescribeMacro\ctan{<identifier>}
+% As detailed above, this macro defines the CTAN identifier of the
+% package, which is (optionally) used in the \cs{maketitle} macro.
+%
+% \DescribeMacro\repository{<url>}
+% Again, as detailed above this macro defines the URL of a source code
+% repository containing a development version of the package, which
+% is optionally used by \cs{maketitle}.
+%
+% \DescribeMacro\author{<name>}
+% Defines the name of the package author. This is used by
+% \cs{maketitle} and is mandatory if \cs{maketitle} is used.
+%
+% \DescribeMacro\email{<email>}
+% Defines the email of the package author. This is used by
+% \cs{maketitle} and is mandatory if \cs{maketitle} is used.
+%
+% \DescribeMacro\title{<title>}
+% Defines the package title. By default, the \cs{package} macro sets
+% a sensible title that should suit most packages, but using \cs{title}
+% will override this title (useful for \emph{e.g.} document classes or
+% \hologo{BibTeX} styles).
+%
+% Three macros retrieving the set metadata are also available. They
+% can be used to typeset the current version of the package, and the
+% package name, respectively.
+%
+% \DescribeMacro\theversion
+% Returns the version as defined by \cs{version}, with a leading
+% \enquote{v}. That is, issuing \Macro\version{1.0} makes
+% \cs{theversion} print \enquote{v1.0}.
+%
+% \DescribeMacro\thepackage
+% \DescribeMacro\thepkg
+% The \cs{thepackage} and \cs{thepkg} macros return the package name
+% as defined by the \cs{package} macro, enclosed in \cs{pkg*}. That is,
+% the package name is typeset as a package but not indexed.
+%
+% \subsubsection{The preamble}
+% The preamble of any documentation most often consists of a title page
+% containing an abstract, and possibly a table of contents. The \thepkg
+% \ package provides macros and environments that typeset such things,
+% and these should be fully compatible with most other document classes.
+%
+% \DescribeMacro\maketitle
+% The \cs{maketitle} macro typesets a title page. This title page uses
+% the metadata defined by the macros described earlier, and typesets
+% them in a manner which is illustrated by the documentation of this
+% class. This style is inspired by \pkg{skrapport}, which is in turn
+% inspired by the title pages of the Prac\TeX\ Journal.
+%
+% \DescribeEnv[<package abstract>]{abstract}
+% The \env{abstract} environment typesets an abstract of the package.
+% Again, its style is illustrated by this document and it is inspired
+% by the \pkg{skrapport} package as well as the Prac\TeX\ Journal.
+%
+% \DescribeMacro\tableofcontents
+% Finally, a Table of Contents may be printed. The actual table of
+% contents is provided by the \pkg{scrartcl} document class, but \thepkg
+% \ redefines a couple of the internal macros to style the Table of
+% Contents in a manner similar to that of the \pkg{microtype} manual.
+%
+% \subsubsection{The LPPL license}
+% \DescribeMacro\PrintLPPL
+% If the LPPL license is present in a directory where \LaTeX\ can find
+% it, in a file called \file{lppl.tex}, then \cs{PrintLPPL} will
+% include the entire LPPL license in the document, and typeset it in
+% a fairly compact manner.
+%
+% \subsubsection{Notices and warnings}
+% The document class provides macros to indicate information that may
+% be of extra importance in the documentation. Such information is
+% categorized as either notices or warnings, which are treated
+% differently.
+%
+% \DescribeMacro\Notice{<notice>}
+% A notice is a short piece of text that contains information that may
+% explain some unexpected but unharmful behaviour of a macro or similar.
+% It is typeset inline, emphasized and in parantheses --- as such, the
+% sequence \Macro\Notice{a notice} yields \Notice{a notice}.
+%
+% \DescribeMacro\Warning{<warning>}
+% A warning is a short comment that conveys information that the user
+% must be aware of. This includes unexpected potentially harmful
+% behaviour, deprecation notices and so on. It is typeset in its own
+% \cs{fbox} --- the sequence \Macro\Warning{a warning} yields the
+% following: \Warning{a warning}
+%
+% \DescribeMacro\LongWarning{<warning>}
+% The \cs{LongWarning} macro is a variant of \cs{Warning} that has been
+% adapted for longer texts, possibly including paragraph breaks. Like
+% \cs{Warning}, it is typeset in a box: \LongWarning{a long warning}
+%
+% \subsubsection{Referential macros}\label{sec:ref-macros}
+% The family of macros originating from \cs{cs} are used to typeset
+% various concepts in running text. In addition to adhering to the
+% general format of the corresponding concept, they index their
+% argument. Each of these macros have a starred variant which does
+% not index its argument; use these when appropriate.
+%
+% \DescribeMacro\cs{<command sequence>}
+% Typesets a command sequence, or macro. The argument should be
+% provided without the leading backslash, and the command sequence
+% will be typeset in a monospaced font.
+%
+% \DescribeMacro\env{<environment name>}
+% Typesets an environment name, which will be typeset in a monospace
+% font.
+%
+% \DescribeMacro\pkg{<package name>}
+% Typesets a package, document class or bundle name. The name will
+% be typeset in a sans-serif font.
+%
+% \DescribeMacro\opt{<option>}
+% Typesets a package or document class option. As of \theversion,
+% options are typeset using a monospace font.
+%
+% \DescribeMacro\bib{<\hologo{BibTeX} entry type>}
+% Typesets a \hologo{BibTeX} entry type. The agument should be provided
+% without the leading \texttt{@} sign. The entry type will be typeset
+% in a monospace font.
+%
+% \DescribeMacro\thm{<theme name>}
+% Typesets a theme name. As of \theversion, the theme name will be
+% typeset in an upright serif font.
+%
+% \DescribeMacro\file{<filename>}
+% Typesets a filename. As of \theversion, the filename will be typeset
+% in a monospace font.
+%
+% \subsection{Documenting the package}\label{sec:doc-macros}
+% The documentation part of any \LaTeX\ manual is arguably the most
+% important one, and to facilitate proper typesetting of the
+% documentation \thepkg\ povides a number of different macros, all
+% inspired by or inherited from \pkg{ydoc}. The first of these
+% macros that will be discussed are the macros that typeset differen
+% kinds of arguments in running text.
+%
+% \DescribeMacro\meta{<meta text>}
+% The \cs{meta} macro typesets a placeholder to be placed in an
+% argument. This can be used to refer to arguments and contents of
+% macros and environments described by commands discussed later in
+% this documentation. It is typeset in brackets: \meta{meta text}.
+%
+% \DescribeMacro\marg{<mandatory argument>}
+% \DescribeMacro\oarg{<optional argument>}
+% \DescribeMacro\parg{<picture-style argument>}
+% \DescribeMacro\aarg{<beamer-style argument>}
+% \DescribeMacro\sarg
+% These macros typeset different kinds of arguments (mandatory,
+% optional, picture-style, beamer-style and star arguments,
+% respetively). These can be used to describe arguments, but
+% are mostly used internally. See table~\ref{tab:args} for
+% examples of how these macros are typeset.
+%
+% \begin{table}[tb]
+% \centering
+% \caption{Typesetting arguments}
+% \label{tab:args}
+% \begin{tabular}{ll}
+% \toprule
+% Invokation & Result \\
+% \midrule
+% \Macro\marg{argument} & \marg{argument} \\
+% \Macro\oarg{argument} & \oarg{argument} \\
+% \Macro\parg{argument} & \parg{argument} \\
+% \Macro\aarg{argument} & \aarg{argument} \\
+% \Macro\sarg & \sarg \\
+% \bottomrule
+% \end{tabular}
+% \end{table}
+%
+% \subsubsection{Examples}
+% \DescribeEnv[<example code>]{example}
+% Perhaps the most powerful way to illustrate features of a package
+% is to show their function by examples. This is made possible by
+% the \env{example} environment. By enclosing example code in this
+% environment, the actual code is typeset next to the result it would
+% produce, as seen below\footnote{Note that the showcased \env{example}
+% environment doesn't contain another \env{example} environment --- the
+% environment is not intended to be nested inside itself.}\footnote{The
+% percent characters in the example are caused by the \pkg{docstrip}
+% requirement of prefixing the documentation with them.}:
+% \begin{example}
+% Simply typesetting a
+% \emph{paragraph} may
+% be simple enough, but
+% it should showcase
+% the utility of the
+% environment well enough.
+% \end{example}
+%
+% Note that for this to work the package obviously needs to be loaded.
+% As such, it is probably a good idea to combine the use of \env{example}
+% with the \opt{load} option, so be sure to read up on the caveats of
+% using that option (see page \pageref{ssec:options:load}).
+%
+% Since the \env{example} environment is based on the same mechanisms
+% as \env{MacroCode}, (mostly) the same typesetting properties apply.
+% In particular, the code will be highlighted if \pkg{minted} is
+% available. \Notice{Since the backend utilizes \cs{verbatim}, the
+% usual caveats apply. In particular, leaving whitespace before
+% \cs{end}\marg{example} will result in an extra newline at the end
+% of the displayed code.}
+%
+% \subsubsection{Options}
+% Package options are of course important to describe, and to this
+% end four macros are provided. They aid in describing options of
+% both regular boolean and the more modern key-value syntax. They
+% are intended to be used in a sequence: \\
+% \mbox{\Macro\Option{...}
+% \AlsoMacro\WithValues{...}
+% \AlsoMacro\AndDefault{...}}
+%
+% \DescribeMacro\Option{<option>}
+% \DescribeMacro\Options{<option>,...}
+% These macros typeset an option, and may be followed by the
+% \cs{WithValues} macro \Notice{the with \cs{Options}, only the
+% first option in the list will work with \cs{WithValues}}.
+%
+% \DescribeMacro\WithValues{<value>,...}
+% This macro typesets a comma-separated list of values a specific
+% option can take. It may be followed by the \cs{AndDefault} macro.
+%
+% \DescribeMacro\AndDefault{<default value>}
+% This macro typesets the default value of an option. It may follow
+% either \cs{Options} or \cs{WithValues}.
+%
+% Common constructs using these macros include:
+% \begin{itemize}
+% \item \mbox{\small
+% \Macro\Option{<option>}
+% \AlsoMacro\WithValues{<value>,...}
+% \AlsoMacro\AndDefault{<default>}}
+% \item \mbox{\small
+% \Macro\Options{<option>,no\meta{option}}
+% \AlsoMacro\AndDefault{no\meta{option}}}
+% \end{itemize}
+%
+% \subsubsection{Macros}
+% The \thepkg\ class inherits a number of macros for describing the
+% package macros from the \pkg{ydoc} package. Only four of them are
+% to be considered stable.
+% \LongWarning{
+% The macros \cs{MakeShortMacroArgs} and \cs{DeleteShortMacroArgs}
+% and the environments \env{DescribeMacros} and \env{DescribeMacrosTab}
+% provided by \pkg{ydoc} are unsupported as of \thepkg\ \theversion.
+% They may work, but this is
+% not a guarantee and they are most likely broken or may break other
+% features of \thepkg.
+% }
+%
+% \DescribeMacro\DescribeMacro<\textbackslash macro><macro arguments>
+% The \cs{DescribeMacro} macro documents a macro along with its
+% arguments. Any number of \meta{macro arguments} may follow the macro,
+% and \cs{DescribeMacro} will stop reading arguments on the first
+% non-argument token. The macro will be indexed.
+% \LongWarning{Although \meta{\textbackslash macro} can include
+% \texttt{@} signs, it is not possible to document \LaTeX3-style
+% macros (with underscores and colons) without the following hack:
+% \par \medskip \begingroup
+% \cs*{ExplSyntaxOn} \\
+% \cs*{cs\_set\_protected\_nopar:Npn}\cs*{ExplHack}\texttt{\{} \\
+% \hspace*{2ex}\cs*{char\_set\_catcode\_letter:n}\texttt{\{~58~\}} \\
+% \hspace*{2ex}\cs*{char\_set\_catcode\_letter:n}\texttt{\{~95~\}} \\
+% \texttt{\}} \\
+% \cs*{ExplSyntaxOff} \\
+% \cs*{ExplHack} \\
+% \endgroup }
+%
+% \DescribeMacro\Macro<\textbackslash macro><macro arguments>
+% This is simply a variant of \cs{DescribeMacro} for use in running
+% text. It is equivalent to \cs{MacroArgs}\cs{AlsoMacro}.
+%
+% \DescribeMacro\MacroArgs<macro aguments>
+% This macro formats \meta{macro arguments} the same way
+% \cs{DescribeMacro} does. As with \cs{Macro}, it is used in
+% running text.
+%
+% \DescribeMacro\AlsoMacro<\textbackslash macro><further arguments>
+% This macro should be used inside \meta{macro arguments} of the macros
+% described above, and typesets an additional macro as part of the
+% syntax of the described macro. For instance, the \cs{csname} macro
+% could be described with the sequence
+% \cs*{Macro}\cs*{csname}\texttt{<command sequence name>}
+% \cs*{AlsoMacro}\cs{endcsname}, which would be rendered as
+% \Macro\csname<command sequence name>\AlsoMacro\endcsname\relax.
+%
+% \subsubsection{Environments}
+% In addition to the macros describing macros, \thepkg\ also inherits
+% one environment and one macro to describe environments. These are
+% similar to the macros described previously in both form and function,
+% but lack equivalents for running text.
+%
+% \DescribeMacro\DescribeEnv[<body content>]{<name>}<arguments>
+% This macro describes an environment, in the same way
+% \cs{DescribeMacro} does for macros. The \meta{body content}, which
+% is optional, may be used to indicate what kind of content the
+% environment is designed to contain. The \cs{MacroArgs}
+% macro is automatically inserted before \meta{body content}.
+%
+% \subsubsection{Other entities}
+% The document class also provides macros to describe \hologo{BibTeX}
+% entries and generic themes. The \hologo{BibTeX} entries are described
+% using the \cs{BibEntry} and \cs{WithFields} macros, while themes are
+% described using the \cs{Theme} macro.
+%
+% \DescribeMacro\BibEntry{<entry name>}
+% \AlsoMacro\WithFields[<optional fields>]{<mandatory fields>}
+% These two macros describe a \hologo{BibTeX} entry named
+% \meta{entry name} (\emph{i.e.}, \bib*{\meta{entry name}}) along with
+% its optional and mandatory fields.
+%
+% \DescribeMacro\Theme{<theme name>}
+% This macro describes a theme named \meta{theme name}. These could be
+% used to describe any kind of theme, such as color themes of a
+% document class.
+%
+% \DescribeMacro\DescribeFile{<filename>}
+% This macro describes a special file named \meta{filename}. This
+% could be a configuration file or similar that is either part of
+% the package or something the package reads if available.
+%
+% \subsection{Describing the implementation}
+% In true \TeX\ (and literal programming) fashion the document class
+% also provides ways to describe, in detail, parts of the
+% implementation. The most essential of the implementation environments,
+% without which \thepkg\ doesn't generate any files, is the
+% \env{MacroCode} environment. Other than that, the implementation
+% environments should be compatible with or analogous to the standard
+% \pkg{ltxdoc} document class.
+%
+% \subsubsection{Implementation environments}\label{sec:impl-env}
+% The environments described in this section indicate the
+% implementation of different concepts including macros, environments
+% and options. They each have a starred variant which doesn't print
+% the concept name (only indexes it), and a non-starred variant which
+% does \Notice{inside these environments, \cs{changes} will refer to
+% the relevant entity instead of logging \enquote{general} changes}.
+%
+% Some of the following environment can typeset descriptions of the
+% internal arguments (\texttt{\#1}, \texttt{\#2} \emph{etc.}) to
+% improve readability of the implementation code.
+%
+% \DescribeEnv[<description>]{macro}{<\textbackslash macro>}
+% [<\# of args>]{<arg 1 description>}[<default value>]'...'
+% {<arg n description>}[<default value>]
+% With this environment, the implementation of a macro is described.
+% Note that as with \cs{DescribeMacro}, \LaTeX3-style macros can not
+% be used in \meta{\textbackslash macro} without the catcode hack
+% mentioned earlier.
+%
+% \DescribeEnv[<description>]{environment}{<environment>}
+% [<\# of args>]{<arg 1 description>}[<default value>]'...'
+% {<arg n description>}[<default value>]
+% This environment describes the implementation of an environment.
+%
+% \DescribeEnv[<description>]{option}{<option>}
+% This environment describes the implementation of an option.
+%
+% \DescribeEnv[<description>]{bibentry}{<@entry>}
+% This environment describes the implementation of a \hologo{BibTeX}
+% entry type.
+%
+% \DescribeEnv[<description>]{theme}{<theme>}
+% This environment describes the implementation of a theme.
+%
+% \subsubsection{The \env{MacroCode} environment}
+% The \enquote{main event} of the \thepkg\ document class is the
+% \env{MacroCode} environment. It has roughly the same role the
+% \env{macrocode} environment has in the \pkg{docstrip} system, except
+% that it in addition to typesetting the implementation also saves it
+% to the target files.
+%
+% The workflow is simple; before using \env{MacroCode} to export code
+% to a file the file must be declared using \cs{DeclareFile}, which
+% also assigns a key to the file (the default is the filename). This
+% key is passed to the \env{MacroCode} environment, which saves the
+% code to the specified file.
+%
+% \DescribeMacro\DeclareFile['key='<key>',preamble='<preamble>]{<filename>}
+% The \cs{DeclareFile} macro declares a file for future use with
+% \env{MacroCode}. The optional argument is a comma separated list of
+% key-value options, where the possible keys are \texttt{key} and
+% \texttt{preamble}. Here \meta{key} is a key that is used instead
+% of the filename in \env{MacroCode}, and \meta{preamble} is a
+% token or command sequence expanding to a preamble which will be
+% prepended to the file on output.
+%
+% \DescribeMacro\PreambleTo{<\textbackslash token>}{<filename>}
+% Reads the preamble from \meta{filename}. Lines from the file are
+% appended to \meta{\textbackslash token} until a line which does not
+% begin with \texttt{\%\%} is encountered.
+%
+% \DescribeMacro\SelfPreambleTo{<\textbackslash token>}
+% This reads the preamble from the curent file. It is equivalent to
+% the sequence
+% \Macro\PreambleTo{<\textbackslash token>}{\cs*{jobname}.tex}.
+%
+% \DescribeEnv[<implementation>]{MacroCode}{<key>',...'}
+% The \env{MacroCode} environment typesets and exports
+% \meta{implementation} verbatim to the file associated with \meta{key}.
+% As such, it is the analogue of the \env{macrocode} environment from
+% \pkg{ltxdoc}, but does not suffer from some of its drawbacks (the
+% sensitivity to whitespace, for instance). As detailed by the
+% description of the \opt{highlight} option (on page
+% \pageref{ssec:option:highlight}), the environment will highlight
+% the code using \pkg{minted} if possible. Multiple \meta{key}s are
+% allowed, and the code will be written to all corresponding files.
+%
+% \subsubsection{Hiding the implementation}
+% For lagre packages it may be of interest to hide the implementation
+% from the documentation. This is accomplished using the two marker
+% macros \cs{Implementation} and \cs{Finale} (which should be present
+% even if not hiding the implementation), and the switch macro
+% \cs{OnlyDescription}.
+%
+% \DescribeMacro\Implementation
+% This macro indicates the start of the implementation. Normally, this
+% would directly precede the \cs{section} under which the implementation
+% is organized.
+%
+% \DescribeMacro\Finale
+% This macro indicates the end of the implementation. Usually the only
+% things happening after this is the printing of indices, the change
+% log, bibliographies and the end of the \env{document} environment.
+%
+% \DescribeMacro\OnlyDescription
+% This macro, which should be issued in the preamble, indicates that the
+% implementation should be hidden. \Warning{this has the side effect
+% that a page break is inserted where the implementation would normally
+% reside.}
+%
+% \subsection{Documenting changes}
+% One type of useful information you should provide in your
+% documentation is a list of changes. The \thepkg\ document class
+% provides a change list system based on the \pkg{glossaries} package.
+% As such, including a change list in your documentation requires you
+% to run \texttt{makeglossaries} between the first and second \LaTeX\
+% run.
+%
+% \DescribeMacro\changes{<version>}{<description>}
+% The \cs{changes} macro provides the main interface to the change
+% list system, and adds changes to the change list. Each change is
+% added with a \emph{context}; if the macro is issued inside one of
+% the macros described in section~\ref{sec:impl-env}, the concept
+% currenly being described will be the context. Outside these
+% environment, the context is \enquote{general}. For every context
+% and \meta{version}, only one change may be recorded, otherwise
+% \pkg{glossaries} will issue a warning.
+%
+% \DescribeMacro\PrintChanges
+% This macro prints the list of changes. As explained earlier, this
+% requires you to run \texttt{makeglossaries} between the two \LaTeX\
+% runs.
+%
+% \subsection{Producing an index}
+% The macros previously discussed in sections~\ref{sec:ref-macros},
+% \ref{sec:doc-macros} and \ref{sec:impl-env} automatically index their
+% aguments using \pkg{glossaries}. By running \texttt{makeglossaries}
+% you can include an index of all macros, environments, packages and
+% such that are discussed, documented or implemented in your package.
+%
+% \DescribeMacro\PrintIndex
+% Much like the \cs{PrintChanges} macro, this prints the index. As with
+% the list of changes, this requires that you run
+% \texttt{makeglossaries} between the two \LaTeX\ runs.
+%
+% \section{Known issues}
+% A list of current issues is available in the Github repository of this
+% package\footnote{\url{https://github.com/urdh/skdoc/issues}}, but as
+% of the release of \theversion, there are two known issues.
+% \begin{description}
+% \item[\#30] The use of \pkg{expl3}-style macros in \cs{cs} may cause
+% issues when generating a glossary. Since such macros are in general
+% implementation details, a workaround may be to omit the
+% implementation from the output by using \cs{OnlyDescription}.
+% \item[\#34] When generating examples utilizing the documented package,
+% if a previous version of this package is installed on the machine
+% where this generation is done, the installed version will be used
+% instead of the version being documented. This may cause incorrect
+% output or compiler errors. A workaround is to temporarily remove
+% the installed version while generating documentation for the more
+% recent version.
+% \end{description}
+%
+% If you discover any bugs in this package, please report them to the
+% issue tracker in the \thepackage\ Github repository.

+% \subsection{Require packages}
+% We begin with loading the \pkg{scrartcl} KOMA-script class and a
+% few packages we'll be needing.
+% \begin{macrocode}
+\PassOptionsToPackage{log-declarations=false}{xparse}
+\LoadClass[ DIV7,
+ headings=big,
+ numbers=noenddot,
+ abstracton,
+ bibliography=totocnumbered,
+ index=totoc
+ ]{scrartcl}
+% \end{macrocode}
+% These packages are basic low-level things that we use to declare
+% commands, work with strings and so on.
+% \begin{macrocode}
+\RequirePackage{etoolbox,xstring,xparse,atbegshi,kvoptions,pdftexcmds,everyhook}
+% \end{macrocode}
+% Now, higher-level packages we use in our definitions.
+% \begin{macrocode}
+\RequirePackage{verbatim,needspace,marginnote,calc,hyperref,multicol,hologo}
+\RequirePackage[nomain,xindy,numberedsection,order=letter,
+ sanitizesort=false]{glossaries}
+% \end{macrocode}
+% We also include the \pkg{ydoc} packages we'll be extending.
+% \begin{macrocode}
+\RequirePackage{ydoc-code,ydoc-desc}
+% \end{macrocode}
+% The rest is basically just styling.

+% \end{macrocode}
+%
+% \subsection{Error messages}
+% Set up some error message texts for later use.
+% \begin{macrocode}

+% \end{macrocode}
+%
+% \subsection{Booleans}
+% Set up some booleans used throughout the code.
+% \begin{macro}{\g__skdoc_use_minted_bool}
+% The \texttt{use_minted} boolean keeps track of wether we're using
+% \pkg{minted} or not. The default value is \emph{false}.
+% \begin{macrocode}
+\bool_new:N\g__skdoc_use_minted_bool
+\bool_gset_false:N\g__skdoc_use_minted_bool
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\g__skdoc_no_index_bool}
+% The \texttt{no_index} boolean keeps track of wether the indexing
+% macros should write things to the index or not. The default value is
+% \emph{false} (don't not write things to the index).
+% \begin{macrocode}
+\bool_new:N\g__skdoc_no_index_bool
+\bool_gset_false:N\g__skdoc_no_index_bool
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\g__skdoc_in_example_bool}
+% The \texttt{in_example} boolean keeps track of wether we are currently
+% inside an example or not (used mainly by \cs{skdoc@verbatim}). The
+% default value is of course \emph{false}.
+% \begin{macrocode}
+\bool_new:N\g__skdoc_in_example_bool
+\bool_gset_false:N\g__skdoc_in_example_bool
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\g__skdoc_with_implementation_bool}
+% The \texttt{with_implementation} boolean keeps track of wether we are
+% going to typeset the implementation or not. The default value is
+% \emph{true}, and this is only changed by \cs{OnlyDescription}.
+% \begin{macrocode}
+\bool_new:N\g__skdoc_with_implementation_bool
+\bool_gset_true:N\g__skdoc_with_implementation_bool
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\g__skdoc_in_implementation_bool}
+% The \texttt{in_implementation} boolean keeps track of wether we are
+% in the implementation part of the documentation or not. It defaults
+% to \emph{false}, and is changed by \cs{Implementation} and \cs{Finale}.
+% \begin{macrocode}
+\bool_new:N\g__skdoc_in_implementation_bool
+\bool_gset_false:N\g__skdoc_in_implementation_bool
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\g__skdoc_negative_space_bool}
+% This boolean keeps track of the negative spacing added by description
+% environments, allowing \env{MacroCode} to offset it if it follows the
+% start of these environments directly. Bit of a hack, really.
+% \begin{macrocode}
+\bool_new:N\g__skdoc_negative_space_bool
+\bool_gset_false:N\g__skdoc_negative_space_bool
+% \end{macrocode}
+% \end{macro}
+%
+% Finally, we define a helpful conditional based on the last two
+% booleans. It decides wether code in \cs{skdoc@verbatim} is typeset
+% or just output to a file.
+% \begin{macro*}{\__skdoc_if_print_code_p:}
+% \begin{macro*}{\__skdoc_if_print_code:T}
+% \begin{macro*}{\__skdoc_if_print_code:F}
+% \begin{macro}{\__skdoc_if_print_code:TF}
+% \begin{macrocode}
+\prg_new_conditional:Nnn\__skdoc_if_print_code:{p,T,F,TF}{
+ \bool_if:nTF{
+ \g__skdoc_in_implementation_bool &&
+ !\g__skdoc_with_implementation_bool
+ }{
+ \prg_return_false:
+ }{
+ \prg_return_true:
+ }
+}
+% \end{macrocode}
+% \end{macro}
+% \end{macro*}
+% \end{macro*}
+% \end{macro*}
+%
+% \subsection{Options}
+% Define the all options, and process them.
+% \begin{macrocode}
+\SetupKeyvalOptions{
+ family=skdoc,
+ prefix=skdoc@
+}
+\DeclareStringOption{load}[\jobname]
+\DeclareStringOption[british]{babel}
+\DeclareBoolOption[true]{highlight}
+\ProcessKeyvalOptions*
+% \end{macrocode}
+% If the \opt{load} option was used, load the given package if it exists.
+% \begin{macrocode}
+\IfStrEq{\skdoc@load}{}{}{%
+ \IfFileExists{\skdoc@load.sty}{%
+ \RequirePackage{\skdoc@load}
+ }{}
+}
+% \end{macrocode}
+%
+% \subsection{Special case: syntax highlighting}
+% We support syntax highlighting through \pkg{minted}, but only if
+% we're running with unrestricted \cs{write18} access \emph{and}
+% there exists a suitable executable (\texttt{pygmentize}). Since
+% \pkg{minted} bails out without \cs{write18} access, we have to test
+% that before even loading it.
+%
+% \subsubsection{A simple \cs{write18} test}
+% Using the \cs{pdf@shellescape} macro from \pkg{pdftexcmds}, we
+% can define a new conditional that decides if we have unrestricted
+% \cs{write18} or not.
+% \begin{macro*}{\__skdoc_if_shellescape:T}
+% \begin{macro*}{\__skdoc_if_shellescape:F}
+% \begin{macro}{\__skdoc_if_shellescape:TF}
+% \begin{macrocode}
+\prg_new_conditional:Nnn\__skdoc_if_shellescape:{T,F,TF}{
+ \if_cs_exist:N\pdf@shellescape
+% \end{macrocode}
+% If the command sequence exists (it really should), we test to see
+% if it is equal to one. The \cs{pdf@shellescape} macro will be zero
+% if no \cs{write18} access is available, two if we have restricted
+% access and one if access is unrestricted.
+% \begin{macrocode}
+ \if_int_compare:w\pdf@shellescape=\c_one
+ \prg_return_true:
+ \else:
+ \prg_return_false:
+ \fi:
+% \end{macrocode}
+% If the command sequence doesn't exist, we assume that we have
+% unrestricted \cs{write18} access (we probably don't), and let
+% \LaTeX\ complain about it later.
+% \begin{macrocode}
+ \else:
+ \prg_return_true:
+ \fi:
+}
+% \end{macrocode}
+% \end{macro}
+% \end{macro*}
+% \end{macro*}
+%
+% \subsubsection{Testing for an application}
+% In order to find out wether \texttt{pygmentize} is installed, we
+% have to test for its binary. This is done by shelling out to
+% \texttt{which} and reading a temporary file, which means we need
+% a way to delete that file.
+% \begin{macro}{\__skdoc_rm:n}[1]
+% {The file to be removed}
+% \begin{macrocode}
+\cs_new:Npn\__skdoc_rm:n#1{
+ \immediate\write18{rm~#1}
+}
+% \end{macrocode}
+% \end{macro}
+% Now, let's define the actual test. Note that this test will fail
+% on non-unixy platforms (\emph{i.e.} Windows). Deal with it for now.
+% \begin{macro*}{\__skdoc_if_pygmentize:nT}
+% \begin{macro*}{\__skdoc_if_pygmentize:nF}
+% \begin{macro}{\__skdoc_if_pygmentize:nTF}[1]
+% {The name of the binary to check existence of}
+% \begin{macrocode}
+\prg_new_conditional:Nnn\__skdoc_if_pygmentize:{T,F,TF}{
+% \end{macrocode}
+% First, run \texttt{which} to create the temporary file.
+% \begin{macrocode}
+ \immediate\write18{which~pygmentize~&&~touch~\jobname.aex}
+% \end{macrocode}
+% A temporary boolean is defined to hold the result of the test (this
+% is a bit of carco cult programming, any clues as to why placing the
+% result inside \cs{file_if_exists:nTF} doesn't work are welcome), and
+% if the test is successful we remove the temporary file.
+% \begin{macrocode}
+ \bool_set:Nn\l_tmpa_bool{\c_false_bool}
+ \file_if_exist:nT{\jobname.aex}{
+ \__skdoc_rm:n{\jobname.aex}
+ \bool_set:Nn\l_tmpa_bool{\c_true_bool}
+ }
+% \end{macrocode}
+% Finally, the temporary boolean is used to return a result.
+% \begin{macrocode}
+ \if_bool:N\l_tmpa_bool
+ \prg_return_true:
+ \else:
+ \prg_return_false:
+ \fi:
+}
+% \end{macrocode}
+% \end{macro}
+% \end{macro*}
+% \end{macro*}
+%
+% Using the macros defined above, we can test for both \cs{write18}
+% and \texttt{pygmentize}, loading \pkg{minted} and setting a flag
+% if both exist. If the option \opt{highlight} was supplied and set
+% to \texttt{false}, we do nothing.
+% \begin{macrocode}
+\ifskdoc@highlight
+ \IfFileExists{\skdoc@load.sty}{
+ \__skdoc_if_shellescape:TF{
+ \__skdoc_if_pygmentize:TF{
+ \bool_gset_true:N\g__skdoc_use_minted_bool
+% \end{macrocode}
+% Since \pkg{minted} (through \pkg{fancyvrb}) loads \pkg{lineno}, and something
+% above already defines \cs{c@linenumber}, we have to resort to a bit of a hack
+% before we actually load \pkg{minted}.
+% \begin{macrocode}
+ \cs_undefine:N\c@linenumber
+ \cs_undefine:N\cl@linenumber
+ \cs_undefine:N\p@linenumber
+ \cs_undefine:N\thelinenumber
+ \RequirePackage{minted}
+% \end{macrocode}
+% Now that we have \pkg{minted}, we redefine the style of the line
+% numbers to match what we have further down for the non-highlighted
+% mode.
+% \begin{macrocode}
+ \renewcommand{\theFancyVerbLine}{
+ \sffamily\tiny\textcolor{lightgray}{
+ \oldstylenums{\arabic{FancyVerbLine}}}
+ }
+% \end{macrocode}
+% We also define our own Pygments style, to match the \thepackage%
+% color theme. This is a bunch of code generated by running
+% \texttt{pygmentize -S default -f latex}, with modifications. Note
+% the abundancy of \verb|#| characters; this is somewhat black magic,
+% but apparently \LaTeX\ expands them one more time than I'd expect
+% in this context. Probably a \LaTeX3 artifact. Also, the macro names
+% somehow correspond to Pygments entities (see \emph{e.g.}
+% \texttt{pygmentize -S default -f html}), but it's not entirely
+% apparent which macro corresponds to what entity.
+% \begin{macrocode}
+ \def\PY@reset{\let\PY@it=\relax \let\PY@bf=\relax%

+% \begin{macrocode}
+ \iow_now:Nx\minted@code{\the\verbatim@line}%

+% \end{macrocode}

+% If we're using \pkg{minted}, we still have to actually print the code.
+% We begin with closing the output file.

+% A few spacing fixes are applied. Since \pkg{minted} uses
+% \pkg{fancyvrb}, these negative \cs{vspace}s are derived from the

+% Now, the internal \pkg{minted} macro \cs{minted@pygmentize} is called
+% to highlight and typeset the code, and the temporary file is removed.
+% \begin{macrocode}
+ \minted@pygmentize{latex}%
+ \DeleteFile{\jobname.pyg}%
+% \end{macrocode}
+% This is followed by more space-offsetting.
+% \begin{macrocode}
+ \vspace*{-\topsep}
+ \vspace*{-\partopsep}

+% \end{macrocode}
+% If we aren't using \pkg{minted}, we hack spaces with \cs{@esphack}

+% \subsection{Styling}

+% First, we redefine a couple of colors from \pkg{ydoc} as well as
+% defining a couple for ourselves.
+% \begin{macrocode}
+\definecolorset{RGB}{}{}{
+ section,11,72,107;

+ scriptcolor,140,35,24;
+ optioncolor,73,10,61;
+ opt,73,10,61
+}
+% \end{macrocode}
+% \subsubsection{Fonts}
+% Then we redefine a couple of the KOMA-script font commands to use
+% our newly defined colors, along with other fixes.
+% \begin{macrocode}
+\RenewDocumentCommand\descfont{}{\sffamily\fontseries{sb}}
+\RenewDocumentCommand\sectfont{}{\sffamily\fontseries{sb}}

+\addtokomafont{descriptionlabel}{\color{section}}
+\addtokomafont{sectionentry}{\rmfamily\bfseries}
+\addtokomafont{sectionentrypagenumber}{\rmfamily\bfseries}
+% \end{macrocode}
+% \subsubsection{Configuring \pkg{hyperref}}
+% Finally, we set up \pkg{hyperref} to also use our colors.
+% \begin{macrocode}
+\hypersetup{
+ colorlinks=true,
+ linkcolor=intlink,
+ anchorcolor=intlink,
+ citecolor=black,
+ urlcolor=extlink
+}
+% \end{macrocode}
+%
+% \subsection{Documentation macros}
+% We can now start defining the documentation macros.
+%
+% \subsubsection{Inline referencing}
+% We introduce a couple of macros for referencing various constructs
+% in running text, \emph{i.e.} \cs{cs}-like macros. The starred
+% variants will not index the use, the non-starred variants will.

+% \subsubsection{Descriptional macros}
+% A range of descriptional macros are made available by the \pkg{ydoc}
+% package, but we need to redefine and extend them.
+%
+% We begin with extending.
+% \begin{macro}{\Describe@Macro}[1]
+% {The macro name, including leading backslash}
+% The \cs{Describe@Macro} macro is changed to typeset its agument in
+% a \cs{marginnote} instead of an \cs{fbox}.
+% \begin{macrocode}

+ \read@Macro@arg
+}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\descframe}[1]
+% {Contents to be framed}
+% Similarly, \cs{descframe} is changed to produce an \cs{mbox}
+% instead of an \cs{fbox}.
+% \begin{macrocode}
+\def\descframe#1{%
+ \mbox{\hspace*{1.5\descsep}#1\hspace*{2\descsep}}%
+}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\PrintMacroName}[1]
+% {Macro name to be printed}
+% \cs{PrintMacroName} is hooked to also index the macro name while
+% printing it.
+% \begin{macrocode}

+% \end{macro}
+% \begin{macro}{\PrintEnvName}[2]
+% {Either \cs{end} or \cs{begin}}
+% {Name of the environment to be printed}
+% Similarly to \cs{PrintMacroName}, the \cs{PrintEnvName} is hooked
+% to index the environment when printing the \cs{begin} part of the
+% environment.
+% \begin{macrocode}

+% \end{macrocode}
+% \end{macro}
+%
+% Then we add a few of our own. For instance, we add macros to
+% typeset descriptions of options. We also undefine the \cs{optpar}
+% macro defined by \pkg{ydoc}, since we supersede it with \cs{Option}.
+% \begin{macrocode}

+% {Values of a key-value option}
+% The \cs{WithValues} macro peeks ahead to see if there's an

+% \end{macro}
+% \begin{macro}{\WithFields}[2]

+% \end{macro}
+%
+% A macro for describing themes is supplied.
+% \begin{macro}{\Theme}[1]

+%
+% And finally, a macro for describing files is provided.
+% \begin{macro}{\DescribeFile}[1]

+ }
+ \nobreak\par\noindent\nobreak\ignorespaces
+}
+% \end{macrocode}
+% \end{macro}
+%
+% Lastly, we define an envionment for showing examples. It's quite
+% complex, utilizing (and kind of hacking) \cs{skdoc@verbatim} and
+% typesetting the content using \pkg{l3coffins}.
+%
+% First, three dimensions used in constructing the side-by-side boxes.
+% \begin{macro}{\c__skdoc_example_margin_dim}
+% This dimension, set to half of \cs{baselineskip}, dictates the margin
+% between the content of the coffins and the dividing ruler.
+% \begin{macrocode}
+\dim_const:Nn\c__skdoc_example_margin_dim{0.5\baselineskip}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\c__skdoc_example_linewidth_dim}
+% This dimension sets the width of the dividing ruler.
+% \begin{macrocode}
+\dim_const:Nn\c__skdoc_example_linewidth_dim{1pt}
+% \end{macrocode}
+% \end{macro}
+%
+% Next, three coffins used by the \env{example} environment are defined.
+% One for code, one for the divider and one for the result.
+% \begin{macro}{\l__skdoc_example_code_coffin}
+% \begin{macrocode}
+\coffin_new:N\l__skdoc_example_code_coffin
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\l__skdoc_example_divider_coffin}
+% \begin{macrocode}
+\coffin_new:N\l__skdoc_example_divider_coffin
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\l__skdoc_example_result_coffin}
+% \begin{macrocode}
+\coffin_new:N\l__skdoc_example_result_coffin
+% \end{macrocode}
+% \end{macro}
+%
+% Finally, we can define the actual \env{example} environment!
+% \begin{environment}{example}
+% \changes{1.2}{Print example code next to the result}
+% \begin{macrocode}
+\DeclareDocumentEnvironment{example}{}{
+% \end{macrocode}
+% The environment starts by priting a small header indicating that
+% the content is in fact an example. It also sets a couple of counters
+% and IO variables to trick \cs{skdoc@verbatim} into thinking that it's
+% actually writing to a defined output file.
+% \begin{macrocode}
+ \bool_gset_true:N\g__skdoc_in_example_bool%
+ \minisec{Example:}%
+ \int_zero_new:c{skdoc@output@skdoc@private@example@line}%
+ \tl_if_exist:cTF{skdoc@output@skdoc@private@example}{
+ \tl_clear:c{skdoc@output@skdoc@private@example}
+ }{
+ \tl_new:c{skdoc@output@skdoc@private@example}
+ }
+% \end{macrocode}
+% Next, we calculate the coffin width. We do this locally, not in a
+% global constant, since we may be somewhere where \cs{textwidth}
+% might have changed.
+% \begin{macrocode}
+ \dim_set:Nn\l_tmpa_dim{ \textwidth/2
+ -\c__skdoc_example_margin_dim
+ -\c__skdoc_example_linewidth_dim/2}
+% \end{macrocode}
+% The code coffin is now filled, after clearing it. It'll get filled
+% with the contents of the verbatim environment, typeset like other
+% \env{MacroCode} environments in the document (\emph{i.e.} \pkg{minted}
+% if possible).
+% \begin{macrocode}
+ \coffin_clear:N\l__skdoc_example_code_coffin
+ \vcoffin_set:Nnw\l__skdoc_example_code_coffin{\l_tmpa_dim}
+ \skdoc@verbatim{skdoc@private@example}
+}{
+ \endskdoc@verbatim
+ \vcoffin_set_end:
+% \end{macrocode}
+% Next comes the example result coffin. After clearing it, it gets
+% filled by writing the contents of the token list defined previously
+% (the one \cs{skdoc@verbatim} is tricked into writing to) to a
+% temporary file, then reading that temporary file using \cs{input}.
+% We leave the temporary file behind; cleaning up requires \cs{write18}.
+% Also: Meh.
+% \begin{macrocode}
+ \coffin_clear:N\l__skdoc_example_result_coffin
+ \vcoffin_set:Nnw\l__skdoc_example_result_coffin{\l_tmpa_dim}
+ \iow_open:Nn\skdoc@output{\jobname.skdoc.tmp}
+ \iow_now:Nx\skdoc@output{\tl_to_str:c{skdoc@output@skdoc@private@example}}
+ \iow_close:N\skdoc@output
+ \input{\jobname.skdoc.tmp}
+ \vcoffin_set_end:
+% \end{macrocode}
+% The divider coffin, being dependent on the height of the two previous
+% coffins, is also reset every time. After clearing, we calculate the
+% maximum height of the two coffins, and add two margins (top and
+% bottom). This value is used to typeset a (gray) rule of the width
+% specified earlier (by \cs{c__skdoc_example_linewidth_dim}). Margins
+% are also added to either side of this rule.
+% \begin{macrocode}
+ \coffin_clear:N\l__skdoc_example_divider_coffin
+ \dim_set:Nn\l_tmpa_dim{
+ \dim_max:nn{\coffin_ht:N\l__skdoc_example_code_coffin}%
+ {\coffin_ht:N\l__skdoc_example_result_coffin}
+ + 2\c__skdoc_example_margin_dim}
+ \hcoffin_set:Nn\l__skdoc_example_divider_coffin{
+ \color{lightgray}
+ \hspace*{\c__skdoc_example_margin_dim}
+ \rule{\c__skdoc_example_linewidth_dim}{\l_tmpa_dim}
+ \hspace*{\c__skdoc_example_margin_dim}
+ }
+% \end{macrocode}
+% It's finally time to join and typeset the coffins. We clear a temporary
+% coffin, copy the divider into it, and proceed to attach the example
+% result coffin to the left and the code to the right (vertical centers
+% touching, so that they are \enquote{centered} vertically). The
+% temporary coffin is then typeset.
+% \begin{macrocode}
+ \coffin_clear:N\l_tmpa_coffin
+ \coffin_set_eq:NN\l_tmpa_coffin\l__skdoc_example_divider_coffin
+ \coffin_join:NnnNnnnn\l_tmpa_coffin{l}{vc}%

+ \bool_gset_false:N\g__skdoc_in_example_bool%
+ \vspace*{\c__skdoc_example_margin_dim}\par
+}
+% \end{macrocode}
+% \end{environment}
+%
+% \subsubsection{Implementation environment}

+% The index is based on \pkg{glossaries}, and as such the whole
+% process of adding entries to the index is reduced to adding
+% glossary entries. This is done through two wrapper macros around
+% the \cs{newglossaryentry} macro.
+% \begin{macro}{\@index@}[1]
+% {The key of the index entry}
+% {The text of the index entry}
+% What \cs{@index@} does is to decide wether we are hiding the
+% implementation part of the documentation (discussed later), and
+% wether we are in the actual implementation or not. If we are in
+% the implementation and aren't printing it, we shouldn't add an
+% index entry.
+% \begin{macrocode}
+\DeclareDocumentCommand\@index@{mm}{
+ \__skdoc_if_do_index:T{
+ \@index@@{#1}{#2}
+ }
+}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\@index@@}[2]
+% {The key of the index entry}
+% {The text of the index entry}
+% This macro does the actual adding to the glossary.
+% \begin{macrocode}
+\DeclareDocumentCommand\@index@@{mm}{
+ \newglossaryentry{index-#1}{
+ type=index,
+ name={#2},
+ description={\nopostdesc},
+ sort={#1}
+ }
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Adding index entries}
+% These macros add an index entry with different contents depending
+% on the thing (macro, environment, etc.) that is being indexed. They
+% all have non-starred variants which are used by the referring
+% macros (\cs{cs} \emph{et. al}), and starred variants used by the
+% description macros (the star affects the style of the page number).
+% Each environment first test wether the given entry key exists, and
+% defines a new entry if it doesn't. Then, a usage of the entry is
+% recorded.
+% There is also a exclamation variant that is used by the implementation
+% environments, that typesets a normal use of the entity.
+%
+% Note the duplicate use of \cs{ifglsentryexists} --- this is needed
+% since \cs{@index@} doesn't always add the entity to the index
+% \emph{i.e.} nothing in the implementation is added when we're hiding
+% the implementation.
+% \begin{macro}{\index@macro}[3]
+% {True if this is the starred variant}
+% {True if this is the exclamation variant}
+% {The name of the macro being indexed, without backslash}
+% \begin{macrocode}

+}
+% \end{macrocode}
+% \end{macro}
+%
+% Notice the references to \cs{hyperul}? We need to define that as
+% well. It's simple enough. Note that \cs{GlsAddXdyAttribute} isn't
+% called until later.
+% \begin{macro}{\hyperul}[1]
+% {Word to underline and link}
+% \begin{macrocode}
+\ProvideDocumentCommand\hyperul{m}{
+ \underline{\hyperup{#1}}
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Displaying the index}
+% Displaying the index is very simple. We begin by defining
+% our own \pkg{glossaries} style.
+% \begin{macrocode}
+\newglossarystyle{docindex}{
+ \glossarystyle{indexgroup}
+ \renewcommand*{\glspostdescription}{\unskip\leaders\hbox to 2.9mm{\hss.}\hfill\strut}
+ \renewenvironment{theglossary}{
+ \bool_gset_true:N\g__skdoc_no_index_bool
+ \begin{multicols}{2}
+ \setlength{\parindent}{0pt}
+ \setlength{\parskip}{0pt plus 0.3pt}
+ \let\item\@idxitem
+ }{
+ \end{multicols}
+ \bool_gset_false:N\g__skdoc_no_index_bool
+ }
+ \renewcommand*{\glossaryentryfield}[5]{
+ \item\glsentryitem{##1}\glstarget{##1}{##2}
+ \ifx\relax##4\relax\else\space(##4)\fi
+ ##3\glspostdescription\space ##5}
+ \renewcommand*{\glsgroupheading}[1]{
+ \IfStrEq{##1}{default}{
+ \item{\descfont\glssymbolsgroupname}
+ }{
+ \item{\descfont\glsgetgrouptitle{##1}}
+ }
+ }
+ \renewcommand*{\glsgroupskip}{
+ \par\vspace{15\p@}\relax
+ }
+}
+% \end{macrocode}
+% We follow that up by defining the actual glossay, and making sure
+% to run \cs{makeglossaries} when the preamble is complete.
+% \begin{macrocode}
+\newglossary{index}{ids}{ido}{Index}
+\AtBeginDocument{\makeglossaries}
+% \end{macrocode}
+% \begin{macro}{\PrintIndex}
+% \changes{1.2}{Fixed incorrect reference to boldfaced text}
+% Finally, we define a command \cs{PrintIndex} that prints the index.
+% Note the preamble that describes how the index page numbers work.
+% \begin{macrocode}
+\providecommand*\PrintIndex{%
+ \begingroup
+ \renewcommand*{\glossarypreamble}{
+ Numbers~written~in~italic~refer~to~the~page~where~the~
+ corresponding~entry~is~described;~numbers~underlined~refer~
+ to~the~page~were~the~implementation~of~the~corresponding~
+ entry~is~discussed.~Numbers~in~roman~refer~to~other~
+ mentions~of~the~entry.\par
+ }
+ \printglossary[type=index,style=docindex]
+ \endgroup
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Hacking \pkg{glossaries}}
+% The following redefinition of an internal \pkg{glossaries} macro,
+% provided by \textcite{Talbot13}, makes sure that the underlined
+% and italic page numbers in the index have precedence over the plain
+% nubmer format. In the event that a macro is described and implemented
+% on the same page, the description format (italic) is used.
+% \begin{macro}{\@gls@addpredefinedattributes}
+% \changes{1.4a}{Add Xdy attribute \texttt{@gobble}}
+% \begin{macrocode}
+\RenewDocumentCommand\@gls@addpredefinedattributes{}{
+ \GlsAddXdyAttribute{hyperit}
+ \GlsAddXdyAttribute{hyperul}
+ \GlsAddXdyAttribute{glsnumberformat}
+ \GlsAddXdyAttribute{@gobble}
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{The changelog}
+% The changelog is implemented as a glossary using the
+% \pkg{glossaries} package. We begin by defining a name
+% for general changes, and commands that save the name of
+% the current macro, environment or similar for use by the
+% \cs{changes} macro.
+% \begin{macro}{\generalname}
+% \begin{macrocode}
+\DeclareDocumentCommand\generalname{}{General}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro*}{\@macroname}[1]
+% {Name of the macro being described}
+% \begin{macrocode}
+\DeclareDocumentCommand\@macroname{m}{
+ \def\skdoc@macroname@stylized{\cs*{\expandafter\@gobble\string#1}}
+ \def\skdoc@macroname@key{macro-\expandafter\@gobble\string#1}
+}
+% \end{macrocode}
+% \end{macro*}
+% \begin{macro*}{\@environmentname}[1]
+% {Name of the environment being described}
+% \begin{macrocode}
+\DeclareDocumentCommand\@environmentname{m}{
+ \def\skdoc@macroname@stylized{\env*{\string#1}}
+ \def\skdoc@macroname@key{env-#1}
+}
+% \end{macrocode}
+% \end{macro*}
+% \begin{macro*}{\@optionname}[1]
+% {Name of the option being described}
+% \begin{macrocode}
+\DeclareDocumentCommand\@optionname{m}{
+ \def\skdoc@macroname@stylized{\opt*{\string#1}}
+ \def\skdoc@macroname@key{opt-#1}
+}
+% \end{macrocode}
+% \end{macro*}
+% \begin{macro*}{\@ebibentryname}[1]
+% {Name of the \hologo{BibTeX} entry being described}
+% \begin{macrocode}
+\DeclareDocumentCommand\@bibentryname{m}{
+ \def\skdoc@macroname@stylized{\bib*{\expandafter\@gobble\string#1}}
+ \def\skdoc@macroname@key{bibentry-\expandafter\@gobble\string#1}
+}
+% \end{macrocode}
+% \end{macro*}
+% \begin{macro*}{\@themename}[1]
+% {Name of the theme being described}
+% \begin{macrocode}
+\DeclareDocumentCommand\@themename{m}{
+ \def\skdoc@macroname@stylized{\thm*{\string#1}}
+ \def\skdoc@macroname@key{thm-#1}
+}
+% \end{macrocode}
+% \end{macro*}
+% Along with these we also define the variables they affect as empty.
+% \begin{macrocode}
+\def\skdoc@macroname@stylized{}
+\let\skdoc@macroname@key\@empty
+% \end{macrocode}
+%
+% \subsubsection{Adding changes}
+% Since the changelog is based on \pkg{glossaries}, adding changes
+% amounts to simply adding a glossary entry.
+% \begin{macro}{\changes}[2]
+% {The version in which the changes were made}
+% {A short description of the changes}
+% \changes{1.4a}{Unconditionally add version \enquote{parent} to
+% circumvent strange behaviour by \pkg{glossaries}. Also, gobble
+% page numbers for similar reasons}
+% \begin{macrocode}
+\DeclareDocumentCommand\changes{mm}{%
+ \@bsphack
+ \newglossaryentry{#1}{
+ type=changes,
+ name={v#1},
+ description={\nopostdesc},
+ nonumberlist=true
+ }
+ \ifx\skdoc@macroname@key\@empty
+ \newglossaryentry{#1-general}{
+ type=changes,
+ description={\generalname{}:~#2},
+ parent={#1},
+ sort={0},
+ nonumberlist=true
+ }
+ \glsadd[types=changes,format=@gobble]{#1-general}
+ \else
+ \newglossaryentry{#1-\skdoc@macroname@key}{
+ type=changes,
+ description={\skdoc@macroname@stylized{}:~#2},
+ parent={#1},
+ sort={\skdoc@macroname@key},
+ nonumberlist=true
+ }
+ \glsadd[types=changes,format=@gobble]{#1-\skdoc@macroname@key}
+ \fi
+ \@esphack
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsubsection{Displaying the changelog}
+% Displaying the changelog is equally simple. We begin by defining
+% our own \pkg{glossaries} style.
+% \begin{macrocode}
+\newglossarystyle{changelog}{
+ \glossarystyle{altlist}
+ \renewenvironment{theglossary}{
+ \bool_gset_true:N\g__skdoc_no_index_bool
+ \begin{multicols}{2}\begin{description}
+ }{
+ \end{description}\end{multicols}
+ \bool_gset_false:N\g__skdoc_no_index_bool
+ }
+ \renewcommand*{\glossaryentryfield}[5]{
+ \par\vspace{5\p@}\relax
+ \item[\glsentryitem{##1}\glstarget{##1}{##2}]
+ \mbox{}\par\nobreak\@afterheading
+ }
+ \renewcommand{\glossarysubentryfield}[6]{%
+ \par\hspace*{\itemindent}
+ \glssubentryitem{##2}%
+ \glstarget{##2}{\strut}##4\glspostdescription\space ##6
+ }
+}
+% \end{macrocode}
+% We follow that up by defining the actual glossary, and making sure
+% to run \cs{makeglossaries} when the preamble is complete.
+% \begin{macrocode}
+\newglossary{changes}{gls}{glo}{Changes}
+\AtBeginDocument{\makeglossaries}
+% \end{macrocode}
+% \begin{macro}{\PrintChanges}
+% Finally, we define a command \cs{PrintChanges} that prints the
+% list of changes.
+% \begin{macrocode}
+\DeclareDocumentCommand\PrintChanges{}{%
+ \begingroup
+ \printglossary[type=changes,style=changelog]
+ \endgroup
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Hiding the implementation}
+% We define commands to hide the implementation from the documentation.
+% Here, the ``implementation'' is understood to be everything between
+% the \cs{Implementation} and \cs{Finale} macros. What we do is disable
+% and/or reset page and section counters for the duration of the
+% implementation, and set a shipout hook that simply discards the pages
+% while we are in the implementation. A consquence of this is that we
+% must force a page break between what's before the implementation and
+% what's after, which might look horrible.
+%
+% We define a counter in which we save the page number we had when
+% the implementation started.
+% \begin{macrocode}
+\newcounter{skdoc@impl@page}
+% \end{macrocode}
+% Then we define the shipout hook. Fairly straight-forward.
+% \begin{macrocode}
+\AtBeginShipout{
+ \__skdoc_if_print_code:F{\AtBeginShipoutDiscard}
+}
+% \end{macrocode}
+% \begin{macro}{\OnlyDescription}
+% The \cs{OnlyDescription} macro simply toggles the appropriate toggle.
+% \begin{macrocode}
+\DeclareDocumentCommand\OnlyDescription{}{
+ \bool_gset_false:N\g__skdoc_with_implementation_bool
+}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\Implementation}
+% \changes{1.1a}{Hide references used in the hidden implementation}
+% The \cs{Implementation} macro defines all the sectioning commands
+% to be empty (saving the old ones), clears the page, saves the page
+% number and toggles the appropriate toggle. If \pkg{biblatex} is
+% loaded, we start a new \env{refsection} so that we can hide
+% references used in the implementation from the final bibliography.
+% \begin{macrocode}
+\DeclareDocumentCommand\Implementation{}{
+ \bool_if:NF\g__skdoc_with_implementation_bool{
+ \clearpage
+ \bool_gset_true:N\g__skdoc_in_implementation_bool
+ \let\skdoc@old@part\part
+ \DeclareDocumentCommand\part{som}{}
+ \let\skdoc@old@section\section
+ \DeclareDocumentCommand\section{som}{}
+ \let\skdoc@old@subsection\subsection
+ \DeclareDocumentCommand\subsection{som}{}
+ \let\skdoc@old@subsubsection\subsubsection
+ \DeclareDocumentCommand\subsubsection{som}{}
+ \let\skdoc@old@paragraph\paragraph
+ \DeclareDocumentCommand\paragraph{som}{}
+ \let\skdoc@old@subparagraph\subparagraph
+ \DeclareDocumentCommand\subparagraph{som}{}
+ \cs_if_exist:NTF\refsection{\refsection}{}
+ \setcounter{skdoc@impl@page}{\value{page}}
+ }
+}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\Finale}
+% \changes{1.1a}{Hide references used in the hidden implementation}
+% The \cs{Finale} macro basically just undoes what the
+% \cs{Implementation} macro did. If \pkg{biblatex} is used, the
+% \env{refsection} environment is ended and the (local) bibliography
+% is printed.
+% \begin{macrocode}
+\DeclareDocumentCommand\Finale{}{
+ \bool_if:NF\g__skdoc_with_implementation_bool{
+ \cs_if_exist:NTF\refsection{\printbibliography\endrefsection}{}
+ \clearpage
+ \bool_gset_false:N\g__skdoc_in_implementation_bool
+ \let\part\skdoc@old@part
+ \let\section\skdoc@old@section
+ \let\subsection\skdoc@old@subsection
+ \let\subsubsection\skdoc@old@subsubsection
+ \let\paragraph\skdoc@old@paragraph
+ \let\subparagraph\skdoc@old@subparagraph
+ \setcounter{page}{\value{skdoc@impl@page}}
+ }
+}
+% \end{macrocode}
+% \end{macro}
+%
+% \subsection{Document metadata}
+% \subsubsection{Setting metadata}
+% We override a bunch of the general titlepage macros and add a few
+% of our own. First, we initialize the underlying variables.
+% \begin{macrocode}
+\let\@ctan\@empty%
+\let\@repository\@empty%
+\let\@plainemail\@empty%
+\let\@email\@empty%
+\let\@version\@empty%
+% \end{macrocode}
+% Then, we define the actual macros.
+% \begin{macro}{\package}[2]
+% {A list of key-value options}
+% {The package name}
+% The \cs{package} macro sets the package name of the documentation.
+% The key-value options are \opt{vcs} and \opt{ctan}.
+% \begin{macrocode}
+\DeclareDocumentCommand\package{om}{%
+ \keys_define:nn{skdoc@package}{%
+ vcs .value_required:n = true,%
+ vcs .code:n = \repository{##1},%
+ ctan .code:n = \ctan{##1},%
+ ctan .default:n = #2%
+ }%
+ \IfNoValueTF{#1}{}{\keys_set:nn{skdoc@package}{#1}}%
+ \def\@package{#2}%
+ \title{The~\textbf{\pkg*{\@package}}~package}%
+}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\ctan}[1]
+% {The name of a package or bundle on CTAN}
+% \begin{macrocode}
+\DeclareDocumentCommand\ctan{m}{%
+ \def\@ctan{\url{http://www.ctan.org/pkg/#1}}%
+}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\repository}[1]
+% {The URI of an online repository}
+% \begin{macrocode}
+\DeclareDocumentCommand\repository{m}{%
+ \def\@repository{\url{#1}}%
+}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\email}[1]
+% {The email address of the author}
+% \begin{macrocode}
+\DeclareDocumentCommand\email{m}{%
+ \def\@plainemail{#1}%
+ \def\@email{\href{mailto:\@plainemail}{\@plainemail}}%
+}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\version}[1]
+% {The version of the package, with no leading ``v''}
+% \begin{macrocode}
+\DeclareDocumentCommand\version{m}{%
+ \def\@version{#1}%
+}
+% \end{macrocode}
+% \end{macro}
+% Finally, we set the default package name to \cs{jobname}.
+% \begin{macrocode}
+\package{\jobname}
+% \end{macrocode}
+%
+% \subsubsection{Using metadata}
+% We define two macros that read useful metadata; \cs{theversion}
+% and \cs{thepackage}. These are used internally by \cs{maketitle}.
+% \begin{macro}{\theversion}
+% \begin{macrocode}
+\DeclareDocumentCommand\theversion{}{v\@version}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\thepackage}
+% \begin{macrocode}
+\DeclareDocumentCommand\thepackage{}{\pkg*{\@package}}
+% \end{macrocode}
+% \end{macro}
+% \begin{macro}{\thepkg}
+% \begin{macrocode}
+\DeclareDocumentCommand\thepkg{}{\thepackage}
+% \end{macrocode}
+% \end{macro}
+% Additionally we define \cs{skdocpdfsettings}, which is also used
+% by \cs{maketitle}, to include PDF metadata if the documentation
+% is being compiled using \hologo{pdfLaTeX}.
+% \begin{macrocode}
+\ifpdf
+ \def\skdocpdfsettings{%
+ \hypersetup{%
+ pdfauthor = {\@author\space<\@plainemail>},
+ pdftitle = {\@title},
+ pdfsubject = {Documentation~of~LaTeX~package~\@package},
+ pdfkeywords = {\@package,~LaTeX,~TeX}
+ }%
+ }%
+\else
+ \let\skdocpdfsettings\empty%
+\fi
+% \end{macrocode}
+%
+% \subsection{General document commands}
+% Most of the general document commands are defined by the
+% \pkg{scrartcl} document class we base ourselves on, but a few
+% of them have to be redefined.
+%
+% \subsubsection{Notices and warnings}
+% We define macros to typeset notices and warnings in the documentation
+% text. Notices are typeset as \Notice{this is a notice}, and warnings
+% are typeset as follows: \Warning{this is a warning}
+% A macro for longer warnings is also available:
+% \LongWarning{This is a longer warning.}
+%
+% \begin{macro}{\Notice}[1]
+% {Notice text}
+% \begin{macrocode}
+\DeclareDocumentCommand\Notice{m}{
+ (\emph{\textbf{Note:}~#1})

+% \subsubsection{The title page}

+%
+% \subsection{Cosmetic changes}
+% We perform a couple of cosmetic changes to existing features as
+% well. First, we set a new header/footer style using the KOMA-script
+% \cs{deftripstyle} macro.
+% \begin{macrocode}
+\deftripstyle{skdoc}%
+ {}{}{}%
+ {\small The~\textbf{\pkg*{\@package}}~package,~v\@version}{}{\small\pagemark}
+\AfterBeginDocument{\pagestyle{skdoc}}
+% \end{macrocode}
+% We also redefine the section level format to set the section numbers
+% in the margin, much like the \pkg{microtype} manual.
+% \begin{macrocode}
+\RenewDocumentCommand{\othersectionlevelsformat}{m}{%
+ \makebox[0pt][r]{%
+ \fontfamily{fos}\mdseries\selectfont
+ \csname the#1\endcsname\enskip}%
+}
+% \end{macrocode}
+% Finally, we actually use \pkg{microtype} in the document class, and
+% make sure to disable it in the verbatim environments.
+% Set up microtype properly
+% \begin{macrocode}
+\g@addto@macro\@verbatim{\microtypesetup{activate=false}}
+\AtEndOfClass{%
+ \microtypesetup{expansion,kerning,spacing,tracking}%
+ \DisableLigatures{family = tt*}%
+}
+% \end{macrocode}
+% We also want numbers on the bibliography headings, if we are loading
+% \pkg{biblatex}. If we happen to be loading \pkg{bibtex}, we issue a
+% warning instead.
+% \begin{macrocode}
+\AtBeginDocument{
+ \ifdefined\defbibheading
+ \defbibheading{bibliography}[\bibname]{\section{#1}}
+ \fi
+ \@ifpackageloaded{bibtex}{\msg_warning:nn{skdoc}{bibtex-unsupported}}{}
+}
+% \end{macrocode}
+% Oh, and we want \cs{marginpar}s on the left, not on the right.
+% \begin{macrocode}
+\AtBeginDocument{\reversemarginpar}
+% \end{macrocode}
+%
+% That's it, we're done!
+% \begin{macrocode}
+\endinput
+% \end{macrocode}
+% \iffalse

+% \Finale
+% \section{Installation}
+% The easiest way to install this package is using the package
+% manager provided by your \LaTeX\ installation if such a program
+% is available. Failing that, provided you have obtained the package
+% source (\file{skdoc.dtx} and \file{Makefile}) from either CTAN
+% or Github, running \texttt{make install} inside the source directory
+% works well. This will extract the documentation and code from
+% \file{skdoc.dtx}, install all files into the TDS tree at
+% \texttt{TEXMFHOME} and run \texttt{mktexlsr}.
+%
+% If you want to extract code and documentation without installing
+% the package, run \texttt{make all} instead. If you insist on not
+% using \texttt{make}, remember that \file{skdoc.cls} is generated
+% by running \texttt{tex}, while the documentation is generated by
+% running \texttt{pdflatex}.
