我尝试到处寻找解决方案，但是要么没能找到它，要么它根本不存在。
我有一片森林，我想给每个节点添加一个标签，这样“Deadbeef”将被标记为 1，“Something”将被标记为 1.1，“else”将被标记为 1.2，然后它们的子节点被标记为 1.1.1 等等。
我知道我可以使用\label命令来做到这一点，但是我很懒而且我的树在长大，所以我不想继续简单地编号。
\begin{forest}
for tree={
grow'=0,
align=center,
base=bottom
},
[Deadbeef
[Something
[Generic\\node]
[Other\\ generic node]
[That one\\there]
]
[Else
[Client\\Side
[Become\\data]
[Bathe in\\data]
]
[Server\\Side
[One with\\data]
[Meta\\data
[Update\\main service]
[Update\\database]
]
]
]
[Kindof
[You are\\very kind]
[How much\\for the lot?]
[Really not\\serious]
]
]
\end{forest}
我的绘画工作并不出色，但我希望它能描绘出我想要实现的想法。理想的解决方案应该采用任意大小的树并相应地标记节点（如果我没有说清楚的话）。
编辑 1：标签应该一直到节点。我知道 cfr 的答案，但是级别是手动指定的。我不知道一棵树会有多少个级别，所以我希望这能自动完成。
答案1
请始终提供可编译的代码。 它极大地减少了不确定性，增加了问题得到解答的可能性（a）和（b）以真正帮助提问者的方式，更加高效，对新用户更有帮助，并且通常使生活变得更加轻松。
猜测如何完成你的代码，我也不清楚你是否真的意味着标签或者如果你想改变节点内容。我假设是后者，因为据我所知，标签在这里没有什么意义。也就是说，我认为目标是这样的：
如果是这样：
\begin{forest}
for tree={
grow'=0,
align=center,
base=bottom
},
before typesetting nodes={
for tree breadth-first={
if level=0{temptoksa=1}{
temptoksa/.option=n,
for nodewalk={
while nodewalk valid={u}{u,+temptoksa=.,if level=0{+temptoksa=1}{+temptoksa/.option=n}}
}{},
},
content/.process={ROw2{temptoksa}{content}{#1 #2}}
}
}
[Deadbeef
[Something
[Generic\\node]
[Other\\ generic node]
[That one\\there]
]
[Else
[Client\\Side
[Become\\data]
[Bathe in\\data]
]
[Server\\Side
[One with\\data]
[Meta\\data
[Update\\main service]
[Update\\database]
]
]
]
[Kindof
[You are\\very kind]
[How much\\for the lot?]
[Really not\\serious]
]
]
\end{forest}
顺便说一句，这棵树对我来说看起来不太清晰，因为边缘通常相对于其子节点随机结束。我可能会选择更像这样的东西：
for tree={
grow'=0,
align=center,
font=\sffamily,
},
forked edges,
align middle children,
在树的序言中，align middle children来自自定义库并定义如下：
\forestset{
align middle child/.style={
before typesetting nodes={
if={
> Ow+P {n children}{isodd(##1)}
}{
calign child/.process={
Ow+n {n children}{(##1+1)/2}
},
calign=child edge,
}{},
},
},
align middle children/.style={
for tree={align middle child},
},
}
但这当然只是个人品味的问题。

\documentclass[border=10pt]{standalone}
\usepackage[edges]{forest}
\forestset{
align middle child/.style={
before typesetting nodes={
if={
> Ow+P {n children}{isodd(##1)}

calign child/.process={
Ow+n {n children}{(##1+1)/2}

calign=child edge,
}{},
},

这几乎完全是从@cfr 的回答很好，如果@cfr 发表答案，我很乐意撤回我的帖子。我相信@cfr 也能避免丑闻\addone。所以这只是以防万一……
\documentclass[border=3.14mm]{standalone}
\usepackage[edges]{forest}
\newcommand{\addone}[1]{\pgfmathtruncatemacro{\tmp}{#1+1}\tmp}
\begin{document}
\begin{forest}
set root label/.style={
content/.wrap 2 pgfmath args={\addone{##1}. ##2}{n()}{content()},
},
set node label/.style={
content/.wrap 3 pgfmath args={\addone{##1}.##2 ##3}{n("!r")}{n()}{content()},
},
set node super label/.style={
content/.wrap 4 pgfmath args={\addone{##1}.##2.##3 ##4}{n("!rr")}{n("!u")}{n()}{content()},
},
before typesetting nodes={
