Spratte\thanks{E-mail: jspratte@yahoo.de}} +% \date{Released 2018/03/13} +% \maketitle +% \tableofcontents +% +% \begin{documentation} +% +% \section{Introduction} +% +% This package was inspired by the question +% \href{https://tex.stackexchange.com/questions/419751} +% {getting ducks in example images}. +% It began on the idea to patch \cs{includegraphics} to automatically change its +% behaviour if |example-image-duck| is used, but then it turned out to be a +% simple alternative to the \pkg{blindtext} package. +% +% It is written as a docstrip file: executing |latex duckuments.dtx| generates +% the \file{duckuments.sty} and \file{example-image-duck.tex} file and typesets +% this duckumentation; execute |tex duckuments.dtx| to only generate the files +% \file{duckuments.sty} and \file{example-image-duck.tex}. +% +% For its functionality \file{example-image-duck.tex} must be compiled at least +% once. The sources are hosted on +% \href{https://github.com/Skillmon/ltx_duckuments}{github}. +% +% \textbf{The package does currently only work on \pdfTeX\ and \LuaTeX}. +% +% \section{Duckumentation} +% +% \subsection{Dummy content} +% +% \begin{function}{\duckument} +% \begin{syntax} +% \cs{duckument}\oarg{key=value} +% \end{syntax} +% Produces a duckument with one sectioning entry of each level starting at +% \cs{chapter} (if available) and two variants of the list environment +% \env{itemize}, \env{enumerate}, and \env{description}, one only at top +% level and one with 4~environments nested. The \meta{key=value}s accept every +% key as explained in \autoref{sec:keys}, but not every key has an effect. +% \end{function} +% +% \begin{function}{\blindduck} +% \begin{syntax} +% \cs{blindduck}\oarg{key=value} +% \end{syntax} +% Produces one paragraph of dummy content. The \meta{key=value}s accept every +% key as explained in \autoref{sec:keys}, but not every key has an effect. +% \end{function} +% +% \begin{function}{\ducklist} +% \begin{syntax} +% \cs{ducklist}\meta{*}\marg{environment} +% \end{syntax} +% Sets a list of the specified \meta{environment}, if \meta{*} is given +% \cs{item}\oarg{dummy} is used instead of only \cs{item}. For |description| +% the starred version is used automatically. +% \end{function} +% +% \begin{function}{\ducklistlist} +% \begin{syntax} +% \cs{ducklistlist}\meta{*}\marg{list} +% \end{syntax} +% Sets 4~levels of a nested list of the specified \meta{environment}, if +% \meta{*} is given \cs{item}\oarg{dummy} is used instead of only \cs{item}. +% For |description| the starred version is used automatically. +% \end{function} +% +% \begin{function}{\duckitemize} +% Abbreviation for \cs{ducklist}|{itemize}|. +% \end{function} +% +% \begin{function}{\duckenumerate} +% Abbreviation for \cs{ducklist}|{enumerate}|. +% \end{function} +% +% \begin{function}{\duckdescription} +% Abbreviation for \cs{ducklist}|{description}|. +% \end{function} +% +% \subsection{Other Macros} +% +% \begin{function}{\duckumentsCreateExampleFile} +% Creates the file \file{example-image-duck.tex} in the current working +% directory. +% \end{function} +% +% \begin{function}{\duckumentsDrawRandomDucks} +% Draws \cs{duckuments@randoms} random \pkg{tikzducks} using +% \pkg{Ti\textit{k}Z}. Note that \pkg{duckuments} doesn't load +% \pkg{Ti\textit{k}Z}, this macro is for the use in +% \file{example-image-duck.tex}. +% \end{function} +% +% \subsection{Patches} +% +% The package patches \cs{includegraphics} if it is defined at the time the +% patch is applied (see \autoref{sec:keys}, |immediate|). The patch changes the +% behaviour if |example-image-duck| is used. If that is the case, a random page +% of that document is used. There shouldn't be any change in behaviour if other +% files are used. +% +% The patch is done so that one can use \pkg{tikzducks} ducks without the need +% of loading \pkg{tikz} in a minimal working duckument as example images. +% +% \subsection{Options}\label{sec:keys} +% +% The package and commands which take a \oarg{key=value} accept the following +% options. Some of which only make sense as package options. The +% \textbf{\texttt{bold}} printed value is the one used if you don't specify a +% value. +% \begin{options} +% \item[toc=\textbf{true}$\vert$false] +% If |true| the \cs{duckument} contains a ToC. +% \item[maths=\textbf{both}$\vert$inline$\vert$display$\vert$none] +% If |both| the \cs{blindduck} (which is also used by \cs{duckument}) +% contains both inline and displayed math. With |inline| and |display| the +% respective maths is activated. |none| disables both. +% \item[immediate=\textbf{true}$\vert$false] +% If |true| \cs{includegraphics} is patched during package load time, else +% the patching is done \cs{AtBeginDocument}. +% \end{options} +% +% \end{documentation} +% +% \begin{implementation} +% +% \section{Implementation} +% +% \begin{macrocode} +%<*pkg> +%
