使用带边距的注释来注释文本（无边距注释和脚注）

Question

这是马可波罗所著的《百万富翁》的意大利文版。我在此版本中找到了主要抄本（正文)、“最优”抄本，以及来自其他文献资料的其他抄本（评论 1和评论 2) 为所选抄本添加了原文中所缺失的其他细节。

我想使用与以下代码类似的方法在 LaTeX 中复制类似的模式：

% Main Text
Non hanno ferro per fare aguti;
%  Comment 1
\begin{UnknownEnvironment}
 \textit{Cas.} [ma fano cavechie de legno e con quele conficano le soe nave;]
\end{UnknownEnvironment}
% Please note that at this point, the main text continues
% below right the word “aguti”
ed è grande pericolo a navicare \dots Egli è vero che vi viene un vento$^2$ talvolta la sate,
% Comment 2
\begin{UnknownEnvironment}
 \textit{Pad.} [de verso uno destro de sabione ch'é atorno de quel punto]
\end{UnknownEnvironment}
% Even in this case, the main text continues below right “aguti”
di verso lo sabbion, con tanto caldo che \dots 

更清楚地说，我希望所有注释和所有主要文本都保留在页面的主要部分，并且注释都是可重入的，并且都允许主要文本从中断的同一点继续。

有没有一个包既可以在环境中进行缩进注释，又可以在这样的注释之后，主文本继续在下一个单词的右下方？提前谢谢！

Answer 1

如果您想要对齐文本，可以使用 zref-savepos 包来存储注释前文本结束的位置。请注意，它需要进行一些编译，直到所有引用都得到解析：

\documentclass{article}
\usepackage[italian]{babel}
\usepackage{zref-savepos}
\usepackage{changepage}
\newcounter{mycomment}

\newenvironment{UnknownEnvironment}
 {\unskip\stepcounter{mycomment}\zsavepos{endpar\the\value{mycomment}}%
    \par\bigskip%
    \bfseries%
    \begin{adjustwidth}{3cm}{0cm}}
 {\end{adjustwidth}
  \par\bigskip
  \noindent\hspace*{\dimexpr\zposx{endpar\the\value{mycomment}}sp-\oddsidemargin-1in}\ignorespaces}
\begin{document}

 \textit{Cas.} [ma fano cavechie de legno e con quele conficano le soe nave;]
\end{UnknownEnvironment}
ed è grande pericolo a navicare \dots Egli è vero che vi viene un vento$^2$ talvolta la sate,
% Comment 2
\begin{UnknownEnvironment}

\end{UnknownEnvironment}
% Even in this case, the main text continues below right �aguti�
di verso lo sabbion, con tanto caldo che \dots

Answer 2

这是使用 -package 的解决方案linegoal。它有一个很大的缺陷，即它只适用于\raggedright-text。不过，我相信有一个聪明的解决方案可以解决这个问题。

所创建环境的缩进是通过changepage-package 和adjustwidth-environment 创建的。当然还有其他选择。

\documentclass{article}
\usepackage{linegoal}
\usepackage{changepage}

\newlength{\previousLine}
\newenvironment{UnknownEnvironment}
  {%
    \setlength{\previousLine}{\linewidth}%
    \addtolength{\previousLine}{-\linegoal}
    \par\bigskip%
    \bfseries%
    \begin{adjustwidth}{3cm}{0cm}%
  }

\raggedright
