从页边距绝对定位嵌套枚举标签

Question

我想根据以下方案绝对定位嵌套的枚举标签：

1. Top level - flush with left page margin and all text is
wrapped to the left margin.

  a. Second level - label starts .25in from left page margin
and text is wrapped to the left margin.

    (1) Third level - label starts .5in from left page margin
and text is wrapped to the left margin.

    (a) Fourth level - label starts .5in from left page margin
and text is wrapped to the left margin.

我希望标签在 0 英寸、.25 英寸和 .5 英寸处对齐，并且所有文本都换行到文档的左边距。我费了好大劲才让第一个列表正常工作，但我不知道后续列表要使用哪些值。

一个限制：全部定制必须在序言中完成。我正在使用 Pandoc 从 markdown 生成 LaTeX，因此我无法直接编辑 LaTeX。

Answer 1

也许是这样的：

\documentclass{article}
\usepackage{enumitem, kantlipsum}
\setlist[enumerate]{wide, labelwidth=\parindent}
\setlist[enumerate,1]{labelindent=0pt, labelwidth=\parindent, label=\arabic*.}
\setlist[enumerate,2]{wide=.825cm, label=\alph*.}
\setlist[enumerate,3]{wide=1.25cm, label=(\arabic*)}

\begin{document}
\kant[6]
\begin{enumerate}
  \item \kant[1]
  \item \kant[2]
  \begin{enumerate}
     \item \kant[3]
     \item \kant[4]
     \begin{enumerate}
        \item \kant[5]
      \end{enumerate}
  \end{enumerate}
\end{enumerate}
\end{document}
