+
+This package is a work-in-progress package allowing you to typeset little penguins in LaTeX with PGF/Ti*k*z.
+The [documentation](https://media.githubusercontent.com/media/EagleoutIce/tikzpingus/gh-pages/doc/build/tikzpingus-doc.pdf) will constantly evolve.
+
+----
+
+Ti*k*Zpingus is actively developed by *Florian Sihler* (contact me at: <florian.sihler@uni-ulm.de>) under the [GPLv3 License](LICENSE). I am very happy about every contribution (see [CONTRIBUTING.md](CONTRIBUTING.md)).

+<!-- While GitHub will cleanse the border-radius, I keep it for the future. -->
+[<img style="border-radius:8pt" src="https://github.com/EagleoutIce/tikzpingus/blob/gh-pages/hey-pingu-1.png?raw=true" width="600" />](https://media.githubusercontent.com/media/EagleoutIce/tikzpingus/gh-pages/examples/build/hey-pingu.pdf#page=1)
+</div>
+
+The purpose of this library is to produce one thing: cute penguins. Using the `\pingu`-macro, you can pass an arbitrary amount of options to endow the penguin with many extras or change its complete appearance. Furthermore, most options allow additional arguments, defining the color, text, ...
+<br />
+
+
+<div style="text-align:center">
+
+[<img style="border-radius:8pt" src="https://github.com/EagleoutIce/tikzpingus/blob/gh-pages/hey-pingu-2.png?raw=true" width="600" />](https://media.githubusercontent.com/media/EagleoutIce/tikzpingus/gh-pages/examples/build/hey-pingu.pdf#page=2)
+</div>
+
+While the [documentation](https://media.githubusercontent.com/media/EagleoutIce/tikzpingus/gh-pages/doc/build/tikzpingus-doc.pdf) contains a reference of all options that are available (or at least, that is the plan), most extras should be named relatively intuitive. For example, if you want a small penguin, you add the option `small`.
+If the penguin should be large, you write `large`. If you want the penguin to hold a cup, you write `cup`. If the cup should have a specific color, like blue, you add this via `cup=blue`, ...
+<br />
+
+<div style="text-align:center">
+
+[<img style="border-radius:8pt" src="https://github.com/EagleoutIce/tikzpingus/blob/gh-pages/hey-pingu-3.png?raw=true" width="600" />](https://media.githubusercontent.com/media/EagleoutIce/tikzpingus/gh-pages/examples/build/hey-pingu.pdf#page=3)
+</div>
+
+Currently, most options I have added arose from concrete situations and are not part of "sets". However, some sets do exist, like the `santa` or `devil` collection. If there are more sets in the future, I might add them as first-class components. For now, the [documentation](https://media.githubusercontent.com/media/EagleoutIce/tikzpingus/gh-pages/doc/build/tikzpingus-doc.pdf#appendix.A) contains an [Overview](https://media.githubusercontent.com/media/EagleoutIce/tikzpingus/gh-pages/doc/build/tikzpingus-doc.pdf#appendix.A) of the larger gadgets.
+<br />
+
+<div style="text-align:center">
+
+[<img style="border-radius:8pt" src="https://github.com/EagleoutIce/tikzpingus/blob/gh-pages/hey-pingu-4.png?raw=true" width="600" />](https://media.githubusercontent.com/media/EagleoutIce/tikzpingus/gh-pages/examples/build/hey-pingu.pdf#page=4)
+</div>
+
+If you just load the library by `\usepackage{tikzpingus}` all options will work, and you might want to use the `glows`-option (`\usepackage[glows]{tikzpingus}`) so that lightsabers and other glowing elements look waaay nicer (but may produce artifacts in some pdf-viewers). However, if loading the library takes too long for you, using the `bare` option will drastically reduce the default options available while allowing you to load specific libraries with `\pinguloadlibraries{<list of libraries>}`.
+<br />
+
+<div style="text-align:center">
+
+[<img style="border-radius:8pt" src="https://github.com/EagleoutIce/tikzpingus/blob/gh-pages/hey-pingu-5.png?raw=true" width="600" />](https://media.githubusercontent.com/media/EagleoutIce/tikzpingus/gh-pages/examples/build/hey-pingu.pdf#page=5)
+</div>
+
+Not all gadgets and wing positions work together. While I try to get as many of them working as possible, selecting two different styles of glasses or hats probably looks weird no matter what code I add.
+Nonetheless, there is code implemented to deal with a lot of interactions (e.g., items in different wings, multiple items on the hat, ...), and there are several options to cope with them yourself if the need arises.
+Oh, and by the way, when options are named with `left` and `right` they are always from the penguin-perspective.
+<br />
+
+<div style="text-align:center">
+
+[<img style="border-radius:8pt" src="https://github.com/EagleoutIce/tikzpingus/blob/gh-pages/hey-pingu-6.png?raw=true" width="600" />](https://media.githubusercontent.com/media/EagleoutIce/tikzpingus/gh-pages/examples/build/hey-pingu.pdf#page=6)
+</div>
+
+Clothes are a work in progress for a long time now. While there are pants, shirts, a cape, and a cloak, they interfere with body types and other interaction codes. They work quite well for "not-too-fancy" and exotic combinations, but for more complex scenarios, I just had no time (for now). So feel free to wrap your head around that and open a PR! I would be happy to assist you!

+\clearpage\section{Introduction}
+\subsection{Dependencies}
+
+As this package is constantly work in progress, the concrete dependencies may change any time.
+At the moment, it loads \href{https://www.ctan.org/pkg/pgf}{\TikZ}, which loads a lot of other packages (e.g. \href{https://www.ctan.org/pkg/xcolor}{xcolor}), and \href{https://www.ctan.org/pkg/etoolbox}{etoolbox}.
+Furthermore, the following \TikZ-Libraries are in use:\footnote{A lot of the libraries loaded are important only for specific extras. I plan on cleaning them up.} \textit{intersections}, \textit{shadings}, \textit{patterns.meta}, \textit{decorations.pathmorphing}, and \textit{shapes.symbols}.

+\vfill
+\section{Usage}\label{Usage}
+
+If you just want a penguin, import the package and start with the following:
+\begin{tcblisting}{title={One small penguin},externalize listing=small-pengu}
+\begin{tikzpicture}
+	\pingu
+\end{tikzpicture}
+\end{tcblisting}
+
+There are \textit{a lot} of configuration-options which can be passed as an optional argument via the known |<key>=<value>|-style. See \autoref{Gadget-Overview} for a complete gadget overview.
+\begin{tcblisting}{title={Happy penguin with cup!},externalize listing=happy-cup}
+\begin{tikzpicture}
+	\pingu[left wing wave, right wing grab,
+	       eyes shiny, cup]
+\end{tikzpicture}
+\end{tcblisting}
+Please note, that \say{left} and \say{right} have been chosen from the penguin-perspective.
+
+\clearpage Besides the keys defined by this package, you can use the keys of \TikZ\ and |pgf| as well (the duck was generated by the lovely \href{https://github.com/samcarter/tikzducks}{tikzducks} package):
+\begin{tcblisting}{title={The Reunion},externalize listing=pengu-duck}
+\begin{tikzpicture}
+	\duck
+	\pingu[xshift=2.8cm, yshift=14mm,
+	       eyes wink]
+\end{tikzpicture}
+\end{tcblisting}
+
+\subsection{Using the Coordinates}
+\label{mrk:coordinates}While there are a lot of gadgets available already,
+every penguin is accompanied by \textit{several} adaptive coordinates
+to place custom items, texts,~\ldots\ % TODO: links
+They can be visualized by the \keyref{meta-dots} option.
+Furthermore, some extras create further coordinates themselves!
+All coordinates are available with |<pingu-name>-<coordinate>|.
+While the default name of a penguin is \say{pingu}, it can be
+changed with the name option:
+\begin{tcblisting}{title={Lotta dots},externalize listing=dotted-pengu}
+\begin{tikzpicture}
+	\pingu[meta dots,left wing wave,
+	       right wing grab, name=paula]
+	\node at (paula-belly-center) {X};
+	\node at (paula-foot-left) {Foot};
+\end{tikzpicture}
+\end{tcblisting}
+Lets look at those coordinates in more detail (all labels are to be prefixed by |<pingu-name>-|):

+\paragraph{The Wings}
+This view excluded a lot of special data collected on the wings!
+While there is more information stored for each wing, the following five coordinates are the most important to place items into penguins hand:\vspace*{-1.5em}
+\begin{center}
+	\null\hfill\parbox[c]{2.5\wd\pinguwingright}{\scalebox{2.5}{\usebox\pinguwingright}}\hfill\parbox[c]{4cm}{\centering\small\@declaredcolor{gray}\sffamily And yes, the wings are deliberately placed asymmetrical.\endgraf}\hfill
+	\parbox[c]{2.5\wd\pinguwingleft}{\scalebox{2.5}{\usebox\pinguwingleft}}\hfill\null
+\end{center}
+
+\paragraph{The Body} Similarly to the wing position, different
+body types can change the coordinates (left the \keyref{body type} \textit{chubby} and right the \keyref{body type} \textit{legacy}):
+\begin{center}
+	\resizebox\linewidth!{%
+		\PinguCoords{body type=chubby,wings hug}\quad\PinguCoords{body type=legacy,wings hug}
+	}
+\end{center}
+
+\subsection{Colors}
+A lot of options allow for a color to be passed. In general, you can provide any color that \TikZ\ is happy with! Yet, there are some predefined pingu-colors shipped with this package:
+\def\getCol#1{\pgfmathparse{int(round(#1*255))}\pgfmathresult}
+\def\parseRGB#1,#2,#3;{r:~\getCol{#1}, g:~\getCol{#2}, b:~\getCol{#3}}
+\begin{multicols}{4}
+\begin{itemize}
+	\foreach \col in {main,black,silver,bronze,white,yellow,lightblue,blue,green,red,purple} {
+		\item[{\tikz[baseline=-.6ex]{\fill[pingu@\col,semithick,draw=black] circle (4pt);}}] \footnotesize\strut
+		% somehow outputs, therefore box
+		\setbox0=\hbox{\colorInfoRGB{pingu@\col}\xdef\colorValue{\colorValue}}\rlap{\smash{\raisebox{-2.9mm}{\sffamily\color{gray}\tiny\expandafter\parseRGB\colorValue;}}}%
+		\texttt{pingu@\col}%
+	}
+	\item[] \footnotesize\strut% buffer
+\end{itemize}
+\end{multicols}
+Furthermore, there is the special color {\makeatletter\say{\expandafter\ipingu\expandafter{\@pingu@none}}} which is available for most\footnote{Why just \say{most}? Well, this package is work in progress and I have added the option late, so I may have forgotten to patch some keys.} extras and wing-items. This color prohibits the compartments from being drawn. To be more precise, the package defines the macro \ltex{\\@pingu@none}, which is matched against the selected color.
+
+As an example, lets take a look at the \keyref{cup}-extra, which provides an additional key \keyref{cup straw} to color the straw:
+\begin{tcblisting}{title={Cup without a straw},externalize listing=extra-options}
+\begin{tikzpicture}
+	\pingu[wings grab, cup=pingu@purple,
+	       cup straw=pingu@blue]
+	\pingu[wings grab, cup, xshift=2.8cm,
+	       cup straw=!hide]
+\end{tikzpicture}
+\end{tcblisting}
+As you can see, using \lpingu{!hide}, the straw will not be drawn.
+
+\subsection{Setting the defaults}
+You do not have to re-state every key.
+With \lstinline[language=pingulang]'\pingudefaults' and \lstinline[language=pingulang]'\pingudefaultsappend' (similar, but extends the current options) you can set default-options for all penguins to come:
+\begin{tcblisting}{title={Change the mainstream},externalize listing=update-defaults}
+\begin{tikzpicture}
+	\pingudefaults{wings grab, eyes shiny}
+	\pingu
+	\pingu[left wing shock, xshift=2.8cm]
+\end{tikzpicture}
+\end{tcblisting}
+
+\subsection{Libraries}
+\label{Libraries}\index{Libraries}I've split the penguin features into a set of libraries. While all of them are loaded by default, the |bare| package-option disables the automatic loading of all libraries. They can be loaded (locally to the current group) using |\pinguloadlibrary| and |\pinguloadlibraries| passing on a comma separated list of desired libraries.
+See the full reference or the index to learn which key comes from which library.
+Please note that~--- at the moment~--- not all components of a library are labeled correctly.
+% TODO: already count that? % global let?
+\foreach[count=\i] \l/\xs in \pingu@defaultlibs{\xdef\pingu@defaultlibs@count{\i}}%
+Currently there are the following libraries:
+\foreach[count=\i] \l/\xs in \pingu@defaultlibs{%
+	\ifx\l\empty\else
+	\index{Libraries!\textit{\l}}\textit{\l}\ifnum\numexpr\pingu@defaultlibs@count-1>\i,\space\else
+	\ifnum\pingu@defaultlibs@count=\i\else,~and\space\fi\fi
+	\fi
+}.
+
+\subsection{Changing the wings}
+\label{subsec:wings}As already demonstrated, it is possible to change the wing positions!
+All selected wing-items will adapt to the wing-position (although not all wing-items will make sense with every wing-position).
+Currently, there are the following wing-positions:
+\typesetselection{leftwing}. \say{none} is a special wing-position: it omits the drawing of wings (teaser: every selection has a none-option, which prohibits the part from being drawn)!
+
+For each valid wing-position you can use |wings <position>| to change both wings or |left wing <position>| and |right wing <position>| to change only one wing respectively. The default wing-position is \say{normal}. If you supply multiple options for a wing, only the last one survives.\footnote{For the sake of completeness: \ipingu{wings <position>}, \ipingu{left wing <position>}, and \ipingu{right wing <position>} are just alternatives i prefer: \ipingu{wings=<position>}, \ipingu{left wing=<position>} and \ipingu{right wing=<position>}.}
+This is shown in Box~\say{\nameref{wing-showcase}}.
+
+\begin{tcblisting}{sidebyside=false, title=Wing-Showcase,nameref=Wing-Showcase,externalize listing=wings-showcase,float,phantomlabel=wing-showcase}
+\begin{tikzpicture}
+	\pingu[left wing none, heart=green]
+	\pingu[wings wave, heart=teal, xshift=3.5cm]
+	\pingu[wings hug, heart=orange, xshift=7cm]
+	\pingu[left wing grab, right wing shock, heart=purple,  xshift=10.5cm]
+\end{tikzpicture}
+\end{tcblisting}
+
+\subsection{Changing the eyes}
+\label{mrk:pengu-eye}Just like the wings, there are a couple of different eye-styles to choose from: \typesetselection{lefteye}.
+Similar to the wings, there is a \say{none} and a \say{normal}-option (which is the default).
+Furthermore, the convenient selectors |eyes <style>|, |left eye <style>|, and |right eye <style>| exist as well. All of this is showcased in~Box~\say{\nameref{eye-showcase}}.
+
+\begin{tcblisting}{sidebyside=false,title=Eye-Showcase,nameref=Eye-Showcase,externalize listing=eyes-showcase,float,phantomlabel=eye-showcase}
+\begin{tikzpicture}
+	\pingu[left eye none, heart=green]
+	\pingu[eyes wink, heart=teal, xshift=3.5cm]
+	\pingu[eyes shock, heart=orange, xshift=7cm]
+	\pingu[left eye devil, right eye angry, heart=purple,  xshift=10.5cm]
+\end{tikzpicture}
+\end{tcblisting}
+
+\subsection{Changing other components}
+\label{mrk:pengu-change-comps}Just like for the wings and the eyes, you can change the following body parts:
+\begin{itemize}
+	\itemsep0pt\relax
+	\item The \textit{body type} itself\\*
+		Select from: \typesetselection{bodytype}.
+	\item The \textit{feet} (again with separate left and right)\\*
+		Select from: \typesetselection{leftfoot}.
+	\item The \textit{bill} (does not have left and right, as there is just one)\\*
+		Select from: \typesetselection{bill}.
+	\item The \textit{hairstyle} (does not have left and right)\\*
+		Select from: \typesetselection{hairstyle}.
+\end{itemize}
+For each selection, \say{none} will prohibit the drawing, and \say{normal} is the default chosen. See Box~\say{\nameref{bodyparts-showcase}} for a example.
+\begin{tcblisting}{sidebyside=false,title=Bodyparts-Showcase,nameref=Bodyparts-Showcase,externalize listing=bodyparts-showcase,float,phantomlabel=bodyparts-showcase}
+\begin{tikzpicture}
+	\pingu[bill angry, heart=green]
+	\pingu[feet back, hairstyle none, heart=teal, xshift=3.5cm]
+	\pingu[bill flat, feet simple, heart=orange, xshift=7cm]
+	\pingu[feet none, bill none, heart=purple, xshift=10.5cm]
+\end{tikzpicture}
+\end{tcblisting}
+
+\subsection{Predefined Styles}
+While the penguin options offer the modification of basically every drawing routine (through other styles like |@block|), it is tedious to change them every time.
+So I have started to create some predefined styles, that do change some of the penguins appearance (and are completely new, so beware of bugs):
+\begin{multicols}{2}
+\begin{itemize}
+	\itemsep0pt
+	\foreach \tx/\s in {{draw everything with a line}/{:line}, {fill main penguin}/{:fill}, {draw components with transparency}/{:ghost parts}, {draw all layers with transparency}/{:ghost}, {set main \say{devil}-components}/{:devil},{flip the penguin (swaps left \& right)}/{:back},{do not draw main pingu}/{:hide}} {
+		\item \parbox[t]{.8\linewidth}{\raggedright\texttt{\s}, \tx.} \hfill
+		\parbox[t]{.175\linewidth}{\scalebox{.4}{%
+			\begin{tikzpicture}[baseline=.35\baselineskip]%
+				\pingu[\s]
+			\end{tikzpicture}%
+		}}
+	}
+	\item[] \parbox[t][2.25\baselineskip]{0pt}{}% buffer
+\end{itemize}
+\end{multicols}
+Currently, only some of the styles do affect other items. As an example, consider |:line|, that changes the draw-style of wing-items and extras:
+\begin{tcblisting}{title={Line Penguin},externalize listing=line-pengu}
+\begin{tikzpicture}
+	\pingu[:line, princess crown, silver medal]
+\end{tikzpicture}
+\end{tcblisting}
+
+\subsection{Randomness}
+Each selection (like the wings or the eyes) can receive a special command \lpingu{!random}. If given, the penguin will receive a randomly picked component.
+Please note, that \textit{none} (the component removing it) will never be picked.
+The first line in the example in Box~\say{\nameref{random-penguin}} sets the seed. % we do not externalize this one
+\begin{tcblisting}{title={Random Penguin},nameref={Random Penguin},label=random-penguin,float}
+\pgfmathsetseed{\number\pdfrandomseed}
+\begin{tikzpicture}
+	\pingu[wings=!random,eyes=!random,
+		   body type=!random,
+			left foot=!random,
+			bill=!random,
+			hairstyle=!random]
+\end{tikzpicture}
+\end{tcblisting}
+
+In a more general fashion, there is a \keyref{random from} key for completely random penguins.
+
+\keyexplain{random from}{list}{}
+	You can pass any list of penguin keys and exactly one of them will be selected. You can nest \keyref{random from}-calls. Please note, that the items are not separated by comma but in braces. The first line in the example sets the seed:% do not externalize
+\begin{tcblisting}{}
+\pgfmathsetseed{\number\pdfrandomseed}
+\begin{tikzpicture}
+	\pingu[random from={{eye patch left}{eye patch right}{halo,halo raise=4mm}},random from={{right eye color=pingu@blue}{random from={{bow tie}{gold medal}}}},random from={{eyes=!random}{wings=!random}},body type=legacy]
+\end{tikzpicture}
+\end{tcblisting}
+\endkeyexplain
+
+
+\subsection{Extras}
+An extra is considered everything, that is attached to the main penguin and not to the wings (as those items may be placed separately for both wings).
+Most extras are activated with the format |<extra>=<color>| (the |<color>| option is not mandatory)
+and try to adapt with other extras that have been placed (yet you can place multiple hats if you really like to).  A lot of the extras do offer more keys to customize their appearance.
+They are explained in the full reference (\autoref{sec:full-ref}).
+
+Consider the somewhat overkill-example of \say{\nameref{lord-gadget}}.
+\begin{tcblisting}{title={Lord-Gadget, the penguin},externalize listing=lord-gadget,nameref={Lord-Gadget, the penguin},label=lord-gadget,float}
+\begin{tikzpicture}
+	\pingu[crown 2d=pingu@bronze,
+	       medal=pingu@purple, tie,
+	       eye patch left=teal,
+	       eye patch right=orange,
+	       right wing wave, sunglasses,
+	       glow thick=yellow]
+\end{tikzpicture}
+\end{tcblisting}
+
+\subsection{Wing-Items}
+Wing items are basically just like extras, but they can be selected separately for the left and right wing. Furthermore, they adapt their \textit{default} appearance to the active wing positions (\autoref{subsec:wings}).
+Currently there are the following wing items:
+% add a extra guard not present with the wing items
+\typesetselection[\textit{#1\expandafter\ParseDTLListElement :"#1"\@nil}]{wingitems}.
+They are selected using |<wing item> <left/right>|.
+
+Additionally, they can be customized by \keyref{left item angle} and \keyref{right item angle}, as well as \keyref{left item flip} and \keyref{right item flip}.
+Lets consider an example\ldots
+\begin{tcblisting}{title={Penguin with full wings!}}
+\begin{tikzpicture}[scale=.75]
+	\pingu[lightsaber right=orange,
+	  lollipop left,
+	  right item angle=70,
+	  right wing raise, left wing grab]
+	\pingu[cane left, right item flip,
+	  sign post right={Hi!}, xshift=35mm]
+\end{tikzpicture}
+\end{tcblisting}
+
+\subsection{Clothing}
+Clothing is the newest extension to the collection, at and the moment there is not one \say{real} clothing, that really adapts to the penguins-position.
+I am working on the \textit{cloak}-Clothing at the moment:
+\begin{tcblisting}{title={Pengu-Clothes},externalize listing=clothes}
+\begin{tikzpicture}[scale=.75]
+	\pingu[cloak]
