节点结构类似文件系统

Question

我想绘制一张反映某些文件结构的图片。下面的代码几乎按预期工作。我需要调整节点之间的连接，使它们不从父节点底部的中心开始，而是从左下角附近开始。

我怎样才能做到这一点？

代码：

\documentclass[11pt, oneside]{article}
\usepackage{tikz}                           % super package for complex and awesome drawing

\begin{document}

\usetikzlibrary{trees}
\tikzstyle{every node}=[draw=black,thick,anchor=west,inner sep=2pt,minimum size=1pt]
\tikzstyle{selected}=[draw=cyan,fill=cyan!30]
\begin{tikzpicture}[
  grow via three points={one child at (0.5,-0.7) and
  two children at (0.5,-0.7) and (0.5,-1.4)},   
  edge from parent path={(\tikzparentnode.south) |- (\tikzchildnode.west)}]
  \node {MainFolder-\{version\}}
    child { node [label={[xshift=6.0cm, yshift=-0.58cm, color=gray] Documentation for developers}] {References and Documentation/}
        child { node [draw=none] {main.html} }
        child { node {reference/}
            child { node [draw=none] {...}}
        }
        child [missing] {}
    }
    child [missing] {}
    child [missing] {}
    child [missing] {}
    child { node {release/}
        child { node [draw=none] {libAwesome.a} }
        child { node [draw=none] {libAwesome.dylib} }
    };
\end{tikzpicture}
\tikzstyle{every node}=[] % resets borders of tables
\tikzstyle{selected}=[] % resets selected

\end{document}  

输出：

你必须设置

• 开始edge from parent path
  • parent anchor=south west（将被保存在\tikzparentanchor）
  • + .4cm向右
  • child anchor( \tikzchildanchor) 不需要设置，因为|-路径运算符会处理这个问题（默认.center锚点具有相同的是值为.west);
• 以及增长函数的起点 ( grow via three points)
  • growth parent anchor=west
• 以及增长函数的结束
  • every child node/.style={anchor=west}

代码

\documentclass[tikz]{standalone}
\usetikzlibrary{trees,calc}
\begin{document}
\tikzset{
    every node/.style={
        draw=black,
        thick,
        anchor=west,
        inner sep=2pt,
        minimum size=1pt,
    }
}
\begin{tikzpicture}[
    grow via three points={
        one child at (0.8,-0.7) and two children at (0.8,-0.7) and (0.8,-1.4)
    },
    edge from parent path={
        ($(\tikzparentnode\tikzparentanchor)+(.4cm,0pt)$) |- (\tikzchildnode\tikzchildanchor)
    },
    growth parent anchor=west,
    parent anchor=south west,% = \tikzparentanchor
%   child anchor=west,%        = \tikzchildanchor
%   every child node/.style={anchor=west}% already in "every node"
  ]
  \node {MainFolder-\{version\}}
    child { node [label={[xshift=6.0cm, yshift=-0.58cm, color=gray] Documentation for developers}] {References and Documentation/}
        child { node [draw=none] {main.html} }
        child { node {reference/}
            child { node [draw=none] {\ldots}}
        }
        child [missing] {}
    }
    child [missing] {}
    child [missing] {}
    child [missing] {}
    child { node {release/}
        child { node [draw=none] {libAwesome.a} }
        child { node [draw=none] {libAwesome.dylib} }
    };
\end{tikzpicture}
\end{document}
