如何防止一系列 tikz 节点重叠？

note对于我正在处理的命令，我有以下 MWE 。

\documentclass{article}
\usepackage[a5paper,marginparwidth=15mm]{geometry}
\usepackage{tikzpagenodes}
\usetikzlibrary{calc}
\newcommand\note[2][0pt]{
  \tikz[overlay,remember picture,baseline=-1ex] \coordinate (e);
  \begin{tikzpicture}[remember picture, overlay]
  \path let \p1 = (e), \p2 = (current page marginpar area.west) in node[yshift=-#1,text width=\marginparwidth,align=left,anchor=north west,inner ysep=0pt,inner xsep=0pt,font=\normalfont\tiny\color{red}] at (\x2,\y1) {#2};
  \end{tikzpicture}
}
\usepackage{everypage}
\AddEverypageHook{
    \tikz[remember picture,overlay] {\draw [blue] (current page text area.south west) rectangle (current page text area.north east);}
    \tikz[remember picture,overlay] {\draw [green] (current page marginpar area.south west) rectangle (current page marginpar area.north east);}
}
\begin{document}
\section{\note{Note A}A Test Section}
Nam arcu libero, nonummy eget, consectetuer id, vulputate a, magna.
Donec \note{Note B - pretty long one} vehicula augue eu neque. Pellentesque habitant morbi tristique senectus
et netus et malesuada fames ac turpis egestas. Mauris ut leo. Cras viverra
metus rhoncus sem. \note{Note C} Nulla et lectus vestibulum urna fringilla \note{Note D} ultrices. Phasellus
eu tellus sit \note{Note E} amet tortor gravida placerat. Integer sapien est, iaculis in, pretium
quis, viverra ac, nunc.tus a mi. Morbi ac orci et nisl hendrerit mollis.
\end{document}

我希望Note E将 移至 下方Note D。目前我可以通过精确 手动完成此操作yshift，但我认为这可以轻松完成，无需手动调整。

我可以想到一个算法

  1. 保存音符底部的位置
  2. 放置下一个音符时，检查顶部位置是否小于前一个底部位置
  3. 计算所需yshift

但是作为初学者，我不知道如何在 中实现该行为tikz。任何帮助表示感谢:)

更新

这里还有一个次要问题 - 如果我尝试删除可选参数（只是为了做到这一点\newcommand\note[1]{）我最终会得到错误

! Use of \use@tikzlibrary doesn't match its definition.
\pgfutil@ifnextchar ...1\def \pgfutil@reserved@a { #2}\def \pgfutil@reserved@...
l.20 \section{\note{Note A}A Test Section}

我当然记得更改参考资料。发生了什么事？

答案1

无 - 解决方案calc。

首先，我们检查是否存在节点。如果存在，则计算和tikz@marginpar@node之间的差值（除非前一个注释在不同的页面上）。如果(tikz@[email protected] west)(0pt, 1ex)是小于 0 的部分(0pt, 1ex)太高，因此tikz@marginpar@node使用前一个来定位新节点。
