节点之间带有箭头的森林包

Question

我想知道如何向Forest包语法树添加箭头。我希望不必使用 Tkiz 包来手动绘制东西。我希望绘制类似这样的内容：

我迄今为止的尝试：

\begin{forest}
  [
    E [E[T[T [F [digit]]  ][*][F [digit] ]]]
    [+]
    [T [F [digit]]]
  ]
\end{forest}

Answer 1

我使用命令让它工作了\draw。

\begin{forest}
  [
    E, name=11
    [E,name=7 [T, name=6 [T,name=3 [F,name=2 [digit, name=1]]  ][*][F, name=5 [digit, name=4]  ]]]
    [+]
    [T, name=10 [F, name=9  [digit, name=8 ]]]
  ]
  \draw[->,dotted] (1) to[out=west,in=south west] (2);
  \draw[->,dotted] (2) to[out=north west,in=south west] (3);
  \draw[->,dotted] (3) to[out=north west,in=west] (6);
  \draw[->,dotted] (4) to[out=east,in=south east] (5);
  \draw[->,dotted] (5) to[out=north east,in=east] (6);
  \draw[->,dotted] (6) to[out=north west,in=south west] (7);
  \draw[->,dotted] (8) to[out=east,in=south east] (9);
  \draw[->,dotted] (9) to[out=north east,in=south east] (10);
  \draw[->,dotted] (7) to[out=north west,in=west] (11);
  \draw[->,dotted] (10) to[out=north east,in=east] (11);
\end{forest}
