\title{Tree Macros}
\author{Emma Pease}


\begin{document}

\maketitle

The tree macros package allows one to integrate \TeX\ and Postscript.
For example, one can use \TeX\ to layout a tree and have Postscript
draw the lines.
\begin{center}
 \begin{tabular}{ccc}
&\node{ab}{top node}\\[3ex]
\node{ac}{left node} && \node{c}{right node}\\[3ex]
              && \node{d}{odd node}
\end{tabular}
\nodeconnect{ab}{ac} 
\nodeconnect{ab}{c}
\nodeconnect{c}{d}
\nodecurve[r]{ab}[r]{d}{1in}
\anodeconnect[b]{ac}[l]{d}
\anodecurve[l]{ab}[l]{ac}{1in}
\end{center}

These macros work by defining locations on a page and then
manipulating them in a variety of ways. The commands that created the
above tree are as follows:
 \begin{verbatim}
\begin{tabular}{ccc}
                    &\node{a}{top node}\\[3ex]
\node{b}{left node} &     & \node{c}{right node}\\[3ex]
                    &     & \node{d}{odd node}
\end{tabular}
\nodeconnect{a}{b} 
\nodeconnect{a}{c}
\nodeconnect{c}{d}
\nodecurve[r]{a}[r]{d}{1in}
\anodeconnect[b]{b}[l]{d}
\anodecurve[l]{a}[l]{b}{1in}
\end{verbatim}
  You will notice that four nodes are defined, a, b, c, and d, using the
\verb+\node+ command. These nodes are then connected using the
\verb+\nodeconnect+ and \verb+\nodecurve+ commands.
  
\section{Locating Commands}

Location commands are those that deal with defining a location on a
page.  The basic command
 \begin{center}
\begin{verbatim}
\node{nodename}{object}
\end{verbatim}
\end{center}
  Each node has its name, height, width, and the location of the lower
left hand corner point passed down to postscript where it will remain
until needed. Note that the object will be printed by \TeX\ but the
lines drawn by Postscript. A variant
of this command is
 \begin{center}
\begin{verbatim}
\nodepoint{nodename}[horizontal displace][vertical displace]
\end{verbatim}
\end{center}
  The node's height and width are 0pts, but the location can be
displaced. 

\section{Connecting Commands}

These commands connect two or more nodes. The two basic ones are 
\begin{center}
\begin{verbatim}
\nodeconnect[fromloc]{fromnodename}[toloc]{tonodename}
\nodecurve[fromloc]{fromnodename}[toloc]{tonodename}{depth}
\end{verbatim}
\end{center}
  fromnodename and tonodename must be the names of two existing nodes.
Imagine the node as a box, fromloc and toloc are the locations on that
box to draw the connecting lines.
\begin{center}\nodemargin=9pt
\begin{tabular}{lcr}
tl  & {t}                &{tr}\\[2ex]
{l} & \node{a}{object}   &{r}\\[2ex]
{bl}& {b}                &{br}
\end{tabular}
\nodebox{a}
\end{center}
  The present choices are t [top], b [bottom], l [left], r [right], tl
[topleft], tr [topright], bl [bottomleft], and br [bottomright].
These could be expanded.

Other connecting commands are
\begin{verbatim}
\barnodeconnect[depth]{fromnodename}{tonodename}
\anodeconnect[fromloc]{fromnodename}[toloc]{tonodename}
\anodecurve[fromloc]{fromnodename}[toloc]{tonodename}{depth}
\end{verbatim}
For example,
\begin{center}
\node{c}{\strut This} \node{a}{\strut is} a \node{b}{\strut test} of
barnodeconnect.  
\barnodeconnect{a}{b}
\barnodeconnect[-5pt]{a}{c}
\bigskip\bigskip

\node{c}{\strut This} \node{a}{\strut is} a \node{b}{\strut test}
\node{d}{\strut of} abarnodeconnect.  \node{e}{\strut Note} arrows.
\abarnodeconnect[10pt]{a}{b}
\abarnodeconnect[-10pt]{a}{c}
\abarnodeconnect[-10pt]{b}{d}
\abarnodeconnect[10pt]{e}{d}
\end{center}\bigskip
\begin{verbatim}
\node{c}{\strut This} \node{a}{\strut is} a \node{b}{\strut test} 
of barnodeconnect.  
\barnodeconnect{a}{b}
\barnodeconnect[-5pt]{a}{c}
\bigskip\bigskip

\node{c}{\strut This} \node{a}{\strut is} a \node{b}{\strut test}
\node{d}{\strut of} abarnodeconnect.  \node{e}{\strut Note} arrows.
\abarnodeconnect[10pt]{a}{b}
\abarnodeconnect[-10pt]{a}{c}
\abarnodeconnect[-10pt]{b}{d}
\abarnodeconnect[10pt]{e}{d}
\end{verbatim}
  A negative depth places the bar below the line; a positive depth (or
the default, which is 5pt) places the bar above the line.


A few odd commands
\begin{verbatim}
\nodetriangle{fromnodename}{tonodename}
\end{verbatim}
This creates a triangle whose apex is the bottom of
\verb+fromnodename+ and whose base is the top of \verb+tonodename+. 

\verb+\anodeconnect+ and \verb+\anodecurve+ are the same as
\verb+\nodeconnect+ and \verb+\node-+ \verb+curve+ except that the connecting
line has a arrowhead on it pointing to the second node.


\section{Single Node commands}

These commands adjust something around a single node rather than
connecting nodes.  The basic commands are
 \begin{center}
\begin{verbatim}
\nodebox{nodename}
\nodecircle[depth]{nodename}
\nodeoval{nodename}
\end{verbatim}
\end{center}
They draw, respectively, a box, circle, or oval around the given node.
\begin{center}
\node{a}{node}\hfill \node{b}{node} \hfill \node{c}{node}
\nodebox{a} \nodecircle{b} \nodeoval{c}
\end{center}
  You will probably wish to call these commands after you have called
all the connecting commands you will be using in a particular diagram. 

\section{Parameters}

At the moment there are three parameters that can be changed.  They
are
\begin{itemize}
\item \verb+\nodemargin+ - A node's height and width are defined as
the height plus depth and width of an hbox enclosing the object plus the
nodemargin on each side.  The default is 2pt.

\item \verb+\treelinewidth+ - The width of the lines. The default is .3pt.

\item \verb+\dashlength+ - The length of the dash, if you are using
dashed lines.   The default is 0pt (solid line).\footnote{The length
of the dash and the length between the dashes are the same.  An
exercise for someone who knows postscript and tex is to allow the dash
and the blank to vary in size.}

\item \verb+\arrowwidth+ - the width of the arrowhead in the
      \verb+\anodeconnect+ and \verb+\anodecurve+ commands. Default is
      4 pt.

\item \verb+\arrowlength+ - the length of the arrowhead.  Default is
      4pt. 

\end{itemize}


\section{How to Run}

Add the style file, tree-dvips.sty, 
\begin{verbatim}
\documentstyle[tree-dvips]{article}
\end{verbatim}
Run through \LaTeX\ and send to a postscript printer using dvips
(written by Tomas Rokicki).

\section{Errors}

A multitude of caveats.
\begin{itemize}
  \item Any commands calling nodes must be read while \TeX\ is still
processing the page the nodes are defined on. In other words don't
define the nodes on page 1 and connect them with commands that appear
at the end of the paper.

\item Nodes mentioned in node connecting commands must exist or else
      the job won't print.  

\item Make sure the dvips postscript output is sent to a postscript
printer.  It is possible to send the dvi, but not the postscript,
output to another printer; the lines just won't appear, assuming the
printer ignores specials it doesn't know about.


\end{itemize}
