+# wordcloud
+
+This package (MetaPost, Lua, and LaTeX) allows you to draw wordclouds.
+
+_This package is in beta version, do not hesitate to report bugs, as well as
+requests for improvement. There is lots to do!_
+
+## Github
+
+To allow for easier feedback and bug reporting, this repository has a mirror
+repository on github:
+[https://github.com/chupinmaxime/wordcloud](https://github.com/chupinmaxime/wordcloud)
+
+## Installation
+
+MPchess is on the [ctan](ctan.org) and can be installed via the package manager of your
+distribution [https://www.ctan.org/pkg/wordcloud](https://www.ctan.org/pkg/wordcloud).
+
+### With TeX live under Linux or MacOS
+
+To install `wordcloud` with TeX live, you will have to create the directory `texmf`
+directory in your home.
+```bash
+user $> mkdir ~/texmf
+```
+
+Then, you will have to place the .mp files in the
+`~/texmf/tex/metapost/wordcloud/`.
+
+`wordcloud` consists of 3 files:
+* `wordcloud.mp` (MetaPost) that should be in `~/texmf/metapost/wordcloud/`;
+* `wordcloud.tex` (LaTeX) that should be in `~/texmf/tex/latex/wordcloud/`;
+* `wordcloud.lua` (Lua) that should be in `~/texmf/scripts/wordcloud/`.
+
+### With MikTEX and Windows
+
+These two systems are unknown to the author of MPchess, so we refer to their
+documentation to add local packages:
+[http://docs.miktex.org/manual/localadditions.html](http://docs.miktex.org/manual/localadditions.html)

+\begin{abstract}
+ These \hologo{METAPOST} and \hologo{LuaLaTeX} packages allows drawing
+ wordclouds from a list of words and weights. The algorithm is implemented with
+ \hologo{METAPOST} whereas Lua is used to parse \LaTeX{} commands, to build
+ the list of words and weights from a text file, and to generate
+ \hologo{METAPOST} code interpreted by \package{luamplib}.

+\section{Installation}
+
+\wordcloudpkg is on \ctan{} and can also be installed via the package manager of your
+distribution.
+
+\begin{center}
+ \url{https://www.ctan.org/pkg/wordcloud}
+\end{center}
+
+
+\subsection{With \TeX live under Linux or macOS}
+
+To install \wordcloudpkg with \TeX Live, you will have to create the directory
+\lstinline+texmf+ in your \lstinline+home+.
+
+\begin{commandshell}
+mkdir ~/texmf
+\end{commandshell}
+
+Then, you will have to place the \lstinline+wordcloud.mp+ file in
+\begin{center}
+ \verb+~/texmf/metapost/wordcloud/+
+\end{center}
+
+
+You will also have to place the \lstinline+wordcloud.lua+ file in
+\begin{center}
+ \verb+~/texmf/scripts/wordcloud/+
+\end{center}
+
+And finally, you will have to place the \lstinline+wordcloud.sty+ file in
+\begin{center}
+ \verb+~/texmf/tex/latex/wordcloud/+
+\end{center}
+
+
+
+Once this is done, \wordcloudpkg will be loaded with the classic \MP{}
+input code
+\begin{mpcode}
+input wordcloud
+\end{mpcode}
+
+And for the \hologo{LuaLaTeX} side, \wordcloudpkg will be loaded with
+\begin{latexcode}
+\usepackage{wordcloud}
+\end{latexcode}
+
+\subsection{With Mik\TeX{} and Windows}
+
+These two systems are unknown to the author of \wordcloudpkg, so we
+refer you to the Mik\TeX documentation concerning the addition of local packages:
+\begin{center}
+ \url{http://docs.miktex.org/manual/localadditions.html}
+\end{center}
+
+
+
+\subsection{Dependencies}
+
+
+\wordcloudpkg depends, for the \MP side, of course on \MP~\cite{ctan-metapost},
+but also on \package{metapost-colorbrewer}~\cite{ctan-metapost-colorbrewer} and the
+\package{latexmp} package~\cite{ctan-latexmp}. For the \hologo{LuaLaTeX} side~\cite{ctan-lualatex-doc},
+\wordcloudpkg depends on the \package{luamplib} package~\cite{ctan-luamplib}
+and the \package{xcolor}~\cite{ctan-xcolor}.
+
+
+\section{\hologo{METAPOST} side}
+
+\subsection{Description of the algorithm}
+
+Given a set of words and weights, we first use a
+\emph{scale function} of the weights to scale the words. In this beta version of
+\package{wordcloud}, we only provide a log-based function\footnote{Other scale
+options could be provided in the next versions.}.
+
+Then, we compute a spiral line starting at the center\footnote{There is variants
+of the algorithm that use different line: squared spiral, etc.}.
+
+Then the algorithm is quite simple:
+\begin{algorithmic}[1]
+\Require set of words $(W_i)_{i\in\{1,\dots,N}$ and corresponding weight
+$(w_i)_{i\in\{1,\dots,N}$, and a spiral line $\mathcal{S}$
+\ForAll{$i\in\{1, \dots,N\}$}
+\State Place $W_i$ at the start of $\mathcal{S}$
+\Repeat
+ \State Set $b_\text{draw}:=\text{true}$
+ \ForAll{$j\in{1,\dots,i}$}
+ \If{$W_i\cap W_j\neq\emptyset$}
+ \State Set $b_\text{draw}:=\text{false}$
+ \EndIf
+ \EndFor
+ \If{$b_\text{draw}==\text{true}$}
+ \State Draw $W_i$
+ \Else
+ \State Move $W_i$ along $\mathcal{S}$
+ \EndIf
+\Until{$W_i$ is drawn}
+\EndFor
+\end{algorithmic}
+
+The hard part is making it perform efficiently! According to Jonathan Feinberg,
+Wordle\footnote{One of the first web application to build wordcloud.} uses a
+combination of hierarchical bounding boxes and quadtrees to achieve reasonable
+speeds. Here, with \hologo{METAPOST}, we compute intersections with the bounding
+box of the word.
+
+\begin{remark}
+ \begin{itemize}
+ \item
+ The words with \hologo{METAPOST} are built with the \lstinline+textext()+
+ function of \package{latexmp} or \package{luamplib}. We are trying to use the
+ bounding boxes of the letters when we get an intersection between ``global''
+ bounding boxes to allow placing words nearer of each other. Unfortunately,
+ this does not work for the moment. Any help is welcomed. \medskip
+
+ \item We first tried to compute intersections between words by decomposing the
+ letter using their contours and compute intersection of contours (with
+ \lstinline+intersectiontimes+). Unfortunately, this is much too slow.
+\end{itemize}
+
+\end{remark}
+
+Some explanations can be found here:
+\begin{center}
+ \url{https://www.jasondavies.com/wordcloud/about/}
+\end{center}
+
+\subsection{Main command}
+
+The main command is
+
+\commande|draw_wordcloud(«words», «weights»,«rotation»,«size»)|\smallskip\index{draw_wordcloud@\lstinline+draw_wordcloud+}
+
+\begin{description}
+\item[\meta{words}:] array of strings ;
+\item[\meta{weights}:] array of numerics ;
+\item[\meta{rotation}:] angle for wordcloud drawing;
+\item[\meta{size}:] number of elements in arrays.
+\end{description}
+
+\begin{ExempleMP}
+input wordcloud
+beginfig(0);
+string words[];
+numeric weights[];
+words[1]:="\LaTeX";
+words[2]:="\hologo{METAPOST}";
+words[3]:="Document";
+words[4]:="Lua";
+words[5]:="\TeX";
+weights[1]:=5;
+weights[2]:=4;
+weights[3]:=3.5;
+weights[4]:=3;
+weights[5]:=3;
+draw_wordcloud(words,weights,0,5);
+endfig;
+\end{ExempleMP}
+
+\begin{remark}
+The ``unity'' of weights is not important because internally,
+\package{wordcloud} compute new weights to work
+with the internal scaling function.
+\end{remark}
+
+\subsection{Parameters}
+
+There are few parameters.
+
+\subsubsection{Colors}\label{sec:colors}
+
+You can use set of colors to draw the wordcloud. For that, you have to use the
+following command:
+\commande|wordcloud_use_color(«bool»)|\smallskip\index{wordcloud_use_color@\lstinline+wordcloud_use_color+}
+
+\begin{description}
+ \item[\meta{bool}:] boolean \lstinline+true+ or \lstinline+false+ (default \lstinline+false+).
+\end{description}
+
+\package{wordcloud} provides a set of five colors using the \hologo{METAPOST}
+package \package{metapost-colorbrewer}~\cite{ctan-metapost-colorbrewer}.
+\package{wordcloud} defines an array of \lstinline+color+s and a
+\lstinline+numeric+ to set the colors to use.\index{wordcloud_colors@\lstinline+wordcloud_colors+}\index{wordcloud_colors_number@\lstinline+wordcloud_colors_number+}
+\begin{mpcode}
+% default colors
+wordcloud_colors[1]:=Reds[3][3];
+wordcloud_colors[2]:=Greens[3][3];
+wordcloud_colors[3]:=Blues[3][3];
+wordcloud_colors[4]:=Oranges[3][3];
+wordcloud_colors[5]:=black;
+wordcloud_colors_number:=5;
+\end{mpcode}
+Feel free to modify that variables to customize the colors.
+
+\subsubsection{Scaling}
+
+You can globally scale the picture using the following command:
+\commande|set_wordcloud_scale(«scale»)|\smallskip\index{set_wordcloud_scale@\lstinline+set_wordcloud_scale+}
+
+\begin{description}
+ \item[\meta{scale}:] \lstinline+numeric+.
+\end{description}
+
+\subsubsection{Margins}
+
+You can adjust the margins of the global bounding boxes of words using the
+following command:
+\commande|set_box_margin(«dim»)|\smallskip\index{set_box_margin@\lstinline+set_box_margin+}
+
+\begin{description}
+ \item[\meta{dim}:] a dimension with units (default 0.3pt).
+\end{description}
+
+
+
+\section{\hologo{LuaLaTeX} side}
+
+\package{wordcloud} provides a \hologo{LuaLaTeX} package. It uses the package
+\package{luamplib} to interpret the \hologo{METAPOST} code produced by Lua.
+
+
+\subsection{Main commands}
+
+The first \LaTeX{} command provided by \wordcloudpkg is:
+
+\commande|\wordcloud[«options»]{«list of words and weights»}|\smallskip\index{\wordcloud@\lstinline+\wordcloud+}
+
+where
+\begin{description}
+ \item[\meta{list of words and weights}:] is a list of couples of the form
+ \lstinline+(word1,weight1);(word2,weight2);(word3,weight3);...+
+\end{description}
+
+The second \LaTeX{} command allows to read a text file, to build the list of
+words and weights and draw the wordcloud up to a certain number of words.
+
+\commande|\wordcloudFile[«options»]{«text file»}{«number of words»}|\smallskip\index{\wordcloudFile@\lstinline+\wordcloudFile+}
+
+where:
+\begin{description}
+ \item[\meta{text file}:] is a text file to analyze and from which the
+ wordcloud is build ;
+ \item[\meta{number of words}:] is the number of words composing the wordcloud.
+\end{description}
+
+\subsubsection{Options}
+
+Both of these functions (\lstinline+\wordcloud+ and \lstinline+\wordcloudFile+)
+have the same options:
+
+\begin{description}
+ \item[\texttt{scale=}\meta{value}:] to scale the picture\footnote{Beware
+ that scaling increases the computation time and the values manipulated by
+ \hologo{METAPOST}.} ;
+ \item[\texttt{margin=}\meta{value with units}:] to adjust the margins
+ (default \lstinline+0.3pt+) ;
+ \item[\texttt{rotation=}\meta{angle}:] to rotate (degrees) the words with
+ $\pm$\meta{angle} alternatively (default 0) ;
+ \item[\texttt{usecolor}:] to use color for word drawing (boolean, default
+ \lstinline+false+) as described in section~\ref{sec:colors} ;
+ \item[\texttt{colors=}\meta{list of colors}:] to define a new
+ set of colors as described in section~\ref{sec:colors}\footnote{This needs
+ \package{xcolor} because the colors are converted to rgb coding and then
+ transferred to \hologo{METAPOST}.}.
+\end{description}
+
+
+Here an example:
+\begin{ExempleLaTeX}
+\wordcloud[scale=1,rotate=45,margin=0.5pt,usecolor,colors={red!40,blue!40,green!20!black}]{(Wordcloud,10);(\\hologo{METAPOST},6);(\\LaTeX,7);(Lua,4);(algorithm,3);(code,2);(mathematics,2);(CTAN,2);(mplib,4);(\\hologo{LuaTeX},4);(latexmp,3);(graphism,2)}
+\end{ExempleLaTeX}
+
+\begin{remark}
+Because the list of words and weights is given to Lua, we have to escape the
+\lstinline+\+ to use \LaTeX{} commands.
+\end{remark}
+
+\subsection{Add ignored words}
+
+The Lua function that builds words and weights from a text file ignores some
+words (and characters). For the moment, \package{wordcloud} only includes word
+lists to ignore for English and French.
+
+However, you can add a list of words to ignore with the following command:
+
+\commande|\wordcloudIgnoreWords{«word list»}|\smallskip\index{\wordcloudIgnoreWords@\lstinline+\wordcloudIgnoreWords+}
+
+\begin{description}
+ \item[\meta{word list}:] the list of words, separated with commas, to ignore
+ \lstinline+word1,word2,word3, etc.+
+\end{description}
+
+
+\section{With \texttt{pdftotext}}
+
+Thanks to \package{wordcloud} and the program \texttt{pdftotext}\footnote{It
+should be possible to parse a \pdf{} with \hologo{LuaTeX}, though. See \url{https://tex.stackexchange.com/questions/692930/recovering-the-textual-content-of-a-pdf-file-with-luatex}.} one can
+easily produce the wordcloud of the current \pdf.
+
+For that, you can produce the text file of the \pdf{}:
+\begin{commandshell}
+pdftotext wordcloud-doc-en.pdf
+\end{commandshell}
+and then, you can use the following code:
+\begin{latexcode}
+\wordcloudFile[usecolor]{wordcloud-doc-en.txt}{50}
+\end{latexcode}
+
+This produce the following wordcloud\footnote{Note that, because the wordcloud
+production is slow, we used a separate file to only produce the \pdf{} of the
+wordcloud, without any scaling, and we inserted the result scaling it with \package{graphicx}\cite{ctan-graphicx}.}
+\begin{center}
+ \includegraphics[width=\linewidth]{doc-wc.pdf}
+\end{center}
+
+\section{To do}
+
+Some things to do:
+\begin{itemize}
+ \item Improve intersection of words by using the letters bounding boxes.
+ \item Work on speed of the algorithm.
+ \item Add supported languages (ignored words).
+ \item Improve text file analysis with Lua to build the set of words and
+ weights.
+ \item Build wordcloud inside a shape.
+ \item Add options for rotation of words.
+\end{itemize}
