+# huffman
+
+This METAPOST package allows to draw binary Huffman trees from two
+arrays : a string one, and a value one. It is based on METAOBJ package which
+provides many tools to build trees in general.
+
+_This package is in beta version, do not hesitate to report bugs, as well as
+requests for improvement_.
+
+## Github
+
+To allow for easier feedback and bug reporting, this repository has a mirror
+repository on github:
+[https://github.com/chupinmaxime/huffman](https://github.com/chupinmaxime/huffman)
+
+## Installation
+
+huffman is on the [ctan](ctan.org) and can be installed via the package manager of your
+distribution [https://www.ctan.org/pkg/mpchess](https://www.ctan.org/pkg/huffman).
+
+### With TeX live under Linux or MacOS
+
+To install huffman 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/huffman/`.
+
+Once this is done, huffman will be loaded with the classic
+```metapost
+input huffman
+```
+
+### 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)
+
+## Dependencies
+
+huffman depends on the packages METAPOST: `metaobj` and, if MPchess is not
+used with LuaLaTeX and luamplib, `latexmp`.

+\section{Installation}
+
+\huffman is on \ctan{} and can also be installed via the package manager of your
+distribution.
+
+\begin{center}
+ \url{https://www.ctan.org/pkg/huffman}
+\end{center}
+
+
+\subsection{With \TeX live under Linux or macOS}
+
+To install \huffman 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+huffman.mp+ file in
+\begin{center}
+ \lstinline+~/texmf/metapost/huffman/+
+\end{center}
+
+
+Once this is done, \huffman will be loaded with the classic \MP{}
+input code
+\begin{mpcode}
+input huffman
+\end{mpcode}
+
+\subsection{With Mik\TeX{} and Windows}
+
+These two systems are unknown to the author of \huffman, 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}
+
+
+\huffman depends, of course on \MP~\cite{ctan-metapost}, as well as the packages
+\package{metaobj}~\cite{ctan-metaobj} and---if \huffman is not used with
+\hologo{LuaLaTeX} and the \package{luamplib} package---the \package{latexmp}
+package.
+
+\section{Main Command}
+
+The package \huffman provides one principal command (which is a \MO/ like
+constructor):
+
+\commande|newBinHuffman.«name»(«sizeofarrays»)(«symbarray»,«valuearray»)|\smallskip\index{newBinHuffman@\lstinline+newBinHuffman+}
+
+
+\begin{description}
+ \item[\meta{name}:] is the name of the object;
+ \item[\meta{sizeofarrays}:] is the size (integer) of the arrays;
+ \item[\meta{symbarray}:] is the array of \lstinline+string+ containing the
+ symbols;
+ \item[\meta{valuearray}:] is the array of \lstinline+numeric+ containing the
+ weights associated to the symbols.
+\end{description}
+
+The data arrays should begin at index 1.
+
+\begin{ExempleMP}
+input huffman
+
+beginfig(0);
+string charList[];
+numeric frequency[];
+charList[1]:="a"; frequency[1]:=0.04;
+charList[2]:="b"; frequency[2]:=0.05;
+charList[3]:="c"; frequency[3]:=0.06;
+charList[4]:="d"; frequency[4]:=0.07;
+charList[5]:="e"; frequency[5]:=0.1;
+charList[6]:="f"; frequency[6]:=0.1;
+charList[7]:="g"; frequency[7]:=0.18;
+charList[8]:="h"; frequency[8]:=0.4;
+
+newBinHuffman.myHuff(8)(charList,frequency);
+myHuff.c=origin;
+drawObj(myHuff);
+endfig;
+\end{ExempleMP}
+
+Note that the symbols are composed in mathematical \TeX{} mode.
+\section{Package Options}
+
+You can modify the size of the internal nodes of the tree with the following
+command:
+
+\commande|set_node_size(«dim»)|\smallskip\index{set_node_size@\lstinline+set_node_size+}
+\begin{description}
+ \item[\meta{dim}:] is the diameter with unit of the circle (default: 13pt).
+\end{description}
+
+You can change the color for the symbol boxes with the following command:
+
+\commande|set_leaf_color(«color»)|\smallskip\index{set_leaf_color@\lstinline+set_leaf_color+}
+\begin{description}
+ \item[\meta{color}:] is a \hologo{METAPOST} \lstinline+color+.
+\end{description}
+
+You can hide the bit values printed on the edges of the tree with the following
+boolean
+(\lstinline+true+ by default):
+
+\commande|show_bits|\smallskip\index{show_bits@\lstinline+show_bits+}
+
+Similarly, you can set the following boolean to \lstinline+false+ to hide the
+node values:
+
+\commande|show_node_values|\smallskip\index{show_node_values@\lstinline+show_node_values+}
+
+Finally, you can set the following boolean to \lstinline+false+ to hide the
+leaf values:
+
+\commande|show_leaf_values|\smallskip\index{show_leaf_values@\lstinline+show_leaf_values+}
+
+Here an example combining all these commands and variables.
+
+\begin{ExempleMP}
+input huffman
+
+beginfig(0);
+string charList[];
+numeric frequency[];
+charList[1]:="s_1"; frequency[1]:=2;
+charList[2]:="s_2"; frequency[2]:=4;
+charList[3]:="s_3"; frequency[3]:=2;
+charList[4]:="s_4"; frequency[4]:=12;
+charList[5]:="s_5"; frequency[5]:=8;
+
+set_leaf_color(0.2[white,green]);
+set_node_size(8pt);
+show_bits:=false;
+show_node_values:=false;
+show_leaf_values:=false;
+newBinHuffman.myHuff(5)(charList,frequency);
+myHuff.c=origin;
+drawObj(myHuff);
+endfig;
+\end{ExempleMP}
+
+
+
+\section{\MO/ Tree Options}
+
+Because the Huffman tree is built using the \MO/ tree constructor, the \MO/ tree
+options are available. All of them are not well suited for this application
+mostly because the Huffman tree is built using elementary trees. The
+options we give to the Huffman constructor are passed to all the subtrees.
+
+We give in table~\ref{tab:options} the \MO/ options for the trees that could be
+used for the Huffman constructor.
+
+\begin{table}[ht]
+\centering\small
+\begin{tabular}{HHHp{5.5cm}}
+ \toprule
+ Option & Type & Default & Description \\
+ \midrule
+ treemode & string & "D" & direction in which the tree develops; there are
+ four different possible values: \lstinline+"D"+ (default),
+ \lstinline+"U"+, \lstinline+"L"+ and \lstinline+"R"+\\
+ treeflip & boolean & false & if true, reverses the order of the subtrees\\
+ treenodehsize & numeric & -1pt & if non-negative, all the nodes are assumed to
+ have this width\\
+ treenodevsize & numeric & -1pt & if non-negative, all the nodes are assumed to
+ have this height\\
+ dx & numeric & 0 & horizontal clearance around the tree\\
+ dy & numeric & 0 & vertical clearance around the tree\\
+ hsep & numeric & 1cm & for a horizontal tree, this is the separation be-
+ tween the root and the subtrees\\
+ vsep & numeric & 1cm & for a vertical tree, this is the separation be-
+ tween the root and the subtrees\\
+ hbsep & numeric & 1cm &for a vertical tree, this is the horizontal separation between subtrees;
+ the subtrees are actually put in a \lstinline+HBox+ and the value of this
+ option is passed to the \lstinline+HBox+ constructor\\
+ vbsep & numeric & 1cm & for an horizontal tree, this is the vertical separation between subtrees;
+ the subtrees are actually put in a \lstinline+HBox+ and the value of this
+ option is passed to the \lstinline+HBox+ constructor\\
+ edge & string & "ncline" & name of a connection command (se \MO/
+ documentation)
+ \\
+ Dalign & string & "top" & vertical alignment of subtrees for trees that go
+ down (the root on the top); the other possible
+ values are \lstinline+"center"+ and \lstinline+"bot"+\\
+ \bottomrule
+\end{tabular}
+\caption{Table of \MO/ tree options.}\label{tab:options}
+\end{table}
+
+Here is an example using some of these options.
+
+\begin{ExempleMP}
+input huffman
+
+beginfig(0);
+string charList[];
+numeric frequency[];
+charList[1]:="s_1"; frequency[1]:=2;
+charList[2]:="s_2"; frequency[2]:=4;
+charList[3]:="s_3"; frequency[3]:=2;
+charList[4]:="s_4"; frequency[4]:=12;
+charList[5]:="s_5"; frequency[5]:=8;
+
+newBinHuffman.myHuff(5)(charList,frequency)
+"treemode(R)","treeflip(true)","hsep(1.5cm)", "edge(nccurve)" , "angleA(0)", "angleB(0)";
+myHuff.c=origin;
+drawObj(myHuff);
+endfig;
+\end{ExempleMP}
+
+\section{Access to Nodes and Leaves}
+
+To access the nodes and the leaves, you can use the \lstinline+treeroot+ command
+from \MO/, see the documentation for details.
+
+\commande|ntreepos(Obj(«name»))(«int»,«int»,etc.)|\smallskip\index{ntreepos@\lstinline+ntreepos+}
+
+The sequence of \meta{int} gives the choice of branch where the children are
+numbered from 1 to $n$.
+
+The following example shows a use of this mecanism.
+\begin{ExempleMP}
+input huffman;
+beginfig(0);
+string charList[];
+numeric frequency[];
+charList[1]:="s_1"; frequency[1]:=2;
+charList[2]:="s_2"; frequency[2]:=4;
+charList[3]:="s_3"; frequency[3]:=2;
+charList[4]:="s_4"; frequency[4]:=12;
+charList[5]:="s_5"; frequency[5]:=8;
+
+newBinHuffman.myHuff(5)(charList,frequency);
+myHuff.c=origin;
+ncarcbox(ntreepos(Obj(myHuff))(2,1,2))(ntreepos(Obj(myHuff))(2,2))
+"linestyle(dashed evenly)", "nodesepA(5mm)", "nodesepB(5mm)" ;
+drawObj(myHuff);
+endfig;
+\end{ExempleMP}
+
+Of course, this can only be used in two steps, first build the tree, then
+annotate it.
+
+You can also access the leaves and the nodes using names. During the
+construction of the tree, names are given to leaves and nodes. Because you may
+want to build several Huffman trees, the trees are numbered. You can get the
+current tree number with the following command:
+
+\commande|get_huffmanTreeNbr()|\smallskip\index{get_huffmanTreeNbr@\lstinline+get_huffmanTreeNbr+}
+
+The leaves are numbered during the construction, and the corresponding \MO/
+object is named as follows:
+
+\commande|leaf«leaf number»_«tree number»|\smallskip
+
+The nodes are numbered during the construction, and the corresponding \MO/
+object is named as follows:
+
+\commande|node«node number»_«tree number»|\smallskip
+
+Thanks to \MO/ you can annotate the tree using all the tools \MO/ provides.
+
+\begin{ExempleMP}
+input huffman;
+beginfig(0);
+string charList[];
+numeric frequency[];
+charList[1]:="s_1"; frequency[1]:=2;
+charList[2]:="s_2"; frequency[2]:=4;
+charList[3]:="s_3"; frequency[3]:=2;
+charList[4]:="s_4"; frequency[4]:=12;
+charList[5]:="s_5"; frequency[5]:=8;
+
+newBinHuffman.myHuff(5)(charList,frequency);
+myHuff.c=origin;
+ncarcbox(node2_1)(leaf4_1)
+"linestyle(dashed evenly)", "nodesepA(5mm)", "nodesepB(5mm)" ;
+drawObj(myHuff);
+endfig;
+\end{ExempleMP}
+
+
+
+
+
+
+
+
+\section{Constructors}
+
+The Huffman algorithm uses only three constructors that you can redefine to adapt
+the tree to your needs. Here are the three constructors (roughly commented in
+French) defined in this package. We will not discuss the code here but
+you are free to redefine and adapt it.
+
