This tree structure is a sequence of +% \begin{verbatim} +% .<level><space><text node>.<space> +% \end{verbatim} +% Note that there is a dot in the beginning and another one at the end +% of each node specification. The spaces are very important: if you +% forgot the space before the |level| there will be an error and if +% you forgot the space after the last dot, you don't indicate the end +% of the node. Since an end of line is like a space for \TeX{}, I +% recommand to write a node per line in the source file: it's handy +% and more readeable. +% +% The |level| indicates the node depth in the tree. There is two +% rules you must respect: +% \begin{enumerate} +% \item The root must have the level one. +% \item When you create a node, if the last node have the level $n$, +% the created node must have a level between 2 and $n+1$. +% \end{enumerate} +% In fact, you can indicates a level greater than $n+1$ if one node +% have a level $n$ somewhere in the tree but the result will be +% strange! +% +% A node of level $n$ will be connected to the last node defined which +% has a level lesser or equal to $n$. +% +% For example, the code +% \begin{verbatim} +% \dirtree{% +% .1 /. +% .2 bin. +% .2 home. +% .3 jeancome. +% .4 texmf. +% .5 tex. +% .6 latex. +% .7 dirtree. +% .3 jeancomeson. +% .3 jeancomedaughter. +% .2 usr. +% .3 bin. +% .3 games. +% .4 fortunes. +% .3 include. +% .3 local. +% .4 bin. +% .4 share. +% .5 texmf. +% .6 fonts. +% .6 metapost. +% .6 tex. +% .3 share. +% } +% \end{verbatim} +% give the result +% \dirtree{%^^A +% .1 /. +% .2 bin. +% .2 home. +% .3 jeancome. +% .4 texmf. +% .5 tex. +% .6 latex. +% .7 dirtree. +% .3 jeancomeson. +% .3 jeancomedaughter. +% .2 usr. +% .3 bin. +% .3 games. +% .4 fortunes. +% .3 include. +% .3 local. +% .4 bin. +% .4 share. +% .5 texmf. +% .6 fonts. +% .6 metapost. +% .6 tex. +% .3 share. +% } +% +% Note the |%| after the left brace in the beginning: it's important +% because the first character encountered must be a dot. +% +% \begin{DescribeMacro}{\DTstyle} +% A text node is typeset with the command |\DTstyle|. Its default +% value is |\ttfamily| when you are under \LaTeX{} and |\tt| when you +% are under Plain \TeX{}. You can redefine this macro as you want, +% it is used with the syntax |{\DTstyle{text node}}|, so you can use +% both |\ttfamily| and |\texttt| for example. +% \end{DescribeMacro} +% +% \begin{DescribeMacro}{\DTcomment} +% The |\DTcomment| command allows to put text at the right side, with +% leaders. The syntax is +% \begin{verbatim} +% \DTcomment{comment text} +% \end{verbatim} +% \begin{DescribeMacro}{\DTstylecomment} +% The style of comment is defined by |\DTstylecomment|. Its default +% value is |\rmfamilly| under \LaTeX{} and |\rm| under Plain \TeX{}, +% and it acts like |\DTstyle|. +% Here is an example: the code +% \begin{verbatim} +% \renewcommand*\DTstylecomment{\rmfamily\color{green}\textsc} +% \renewcommand*\DTstyle{\ttfamily\textcolor{red}} +% \dirtree{% +% .1 /. +% .2 bin. +% .2 home. +% .3 jeancome. +% .4 texmf. +% .5 tex. +% .3 jeancomeson\DTcomment{Guillaume}. +% .3 jeancomedaughter\DTcomment{Mathilde}. +% .2 usr. +% .3 bin. +% } +% \end{verbatim} +% give the result +% \begingroup +% \renewcommand*\DTstylecomment{\rmfamily\color{green}\textsc} +% \renewcommand*\DTstyle{\ttfamily\textcolor{red}} +% \dirtree{%^^A +% .1 /. +% .2 bin. +% .2 home. +% .3 jeancome. +% .4 texmf. +% .5 tex. +% .3 jeancomeson\DTcomment{Guillaume}. +% .3 jeancomedaughter\DTcomment{Mathilde}. +% .2 usr. +% .3 bin. +% } +% \endgroup +% In this example we have used the \package{xcolor} package. +% \end{DescribeMacro} +% \end{DescribeMacro} +% +% You can build complex text node. For example, the code +% \begin{verbatim} +% \dirtree{% +% .1 /. +% .2 bin \ldots{} \begin{minipage}[t]{5cm} +% This directory holds executable files (binary +% files or link on binary files){.} +% \end{minipage}. +% .2 home \ldots{} \begin{minipage}[t]{5cm} +% jeancome\\ +% guillaume\\ +% mathilde\\ +% \end{minipage}. +% .4 texmf. +% } +% \end{verbatim} +% give the result +% \dirtree{%^^A +% .1 /. +% .2 bin \ldots{} \begin{minipage}[t]{5cm} +% This directory holds executable files (binary +% files or link on binary files){.} +% \end{minipage}. +% .2 home \ldots{} \begin{minipage}[t]{5cm} +% jeancome\\ +% guillaume\\ +% mathilde\\ +% \end{minipage}. +% .4 texmf. +% } +% We don't encourage to try too complicated code. Package +% \package{dirtree} is still fragile! Note that we pay attention to +% use optional parameter |[t]| in order to have a right vertical +% alignment with horizontal rules. +% +% \begin{DescribeMacro}{\DTsetlength} +% Some dimensions can be changed using the |\DTsetlength| command. The +% syntax is: +% \begin{verbatim} +% \DTsetlength{offset}{width}{sep}{rule-width}{dot-size} +% \end{verbatim} +% \begin{center} +% \begin{pspicture}(0,0)(8,4) +% \psset{linewidth=3pt} +% \psline(1,0)(1,4) +% \psline(1,2)(2.5,2) +% \psline(3.5,0)(3.5,1.75) +% \psset{linewidth=0.4pt} +% \rput[bl](3,2){\framebox{\LARGE Text node}} +% \psframe*(0.75,1.75)(1.25,2.25) +% \psset{linewidth=0.2pt} +% \psline{<->}(0.5,1.75)(0.5,2.25) +% \uput[l](0.5,2){\scriptsize \ttfamily dot-size} +% \psline{<->}(1,2.5)(2.5,2.5) +% \uput[u](1.75,2.5){\scriptsize \ttfamily width} +% \psline{<->}(2.5,2)(3,2) +% \uput[u](2.75,2){\scriptsize \ttfamily sep} +% \psline{<->}(3,1.5)(3.5,1.5) +% \uput[d](3,1.5){\scriptsize \ttfamily offset} +% \end{pspicture} +% \end{center} +% The default value are: +% \begin{itemize} +% \item \texttt{offset = 0.2em} +% \item \texttt{width = 1em} +% \item \texttt{sep = 0.2em} +% \item \texttt{rule-width = 0.4pt} +% \item \texttt{dot-size = 1.6pt} +% \end{itemize} +% +% \begin{DescribeMacro}{\DTbaselineskip} +% The last length parameter is |\DTbaselineskip| which indicates the +% skip between lines of the tree. +% \end{DescribeMacro} +% +% If we typeset the first example with +% \begin{verbatim} +% \setlength{\DTbaselineskip}{20pt} +% \DTsetlength{1em}{3em}{0.1em}{1pt}{4pt} +% \end{verbatim} +% we obtain the (strange) result: +% \begingroup +% \setlength{\DTbaselineskip}{20pt} +% \DTsetlength{1em}{3em}{0.1em}{1pt}{4pt} +% \dirtree{%^^A +% .1 /. +% .2 bin. +% .2 home. +% .3 jeancome. +% .4 texmf. +% .5 tex. +% .6 latex. +% .7 dirtree. +% .3 jeancomeson. +% .3 jeancomedaughter. +% .2 usr. +% .3 bin. +% .3 games. +% .4 fortunes. +% .3 include. +% .3 local. +% .4 bin. +% .4 share. +% .5 texmf. +% .6 fonts. +% .6 metapost. +% .6 tex. +% .3 share. +% } +% \endgroup +% \end{DescribeMacro} %^^A of \DTsetlength +% \end{DescribeMacro} %^^A of \dirtree +% +% Note that \package{dirtree} package is not able to split tree on +% several pages.
