使用 pdfcomment 添加对注释的回复

Question 1

虽然下面的原始答案可能对某些用户有用，但 OP 表示一直希望将所有对话包含在一条评论中。

因此，我添加了这个

替代答案

有了这个答案，完整的对话发生在原始的论点中\pdfcomment。评论中的回复是通过

\addreply{<style-name>} ...

样式名称可预定义，以包含author=字段。在此示例中，样式Jim和Sue已预定义，因此，当用作的参数时\addreply，将使用全author名（“Jim Jones”或“Sue Smith”）。如果样式未定义，则样式名称本身将用作作者。

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[rgb]{xcolor}
\usepackage{pdfcomment}
\usepackage{listofitems}
\let\svdefinestyle\definestyle
\renewcommand\definestyle[2]{%
  \defineauthor{#1}{#2}%
  \svdefinestyle{#1}{#2}%
}
\def\authorstring{author}
\newcommand\defineauthor[2]{%
  \setsepchar{,/=}%
  \readlist*\styleoption{#2}%
  \foreachitem\z\in\styleoption[]{%
    \itemtomacro\styleoption[\zcnt,1]\ztmp
    \ifx\ztmp\authorstring
      \expandafter\xdef\csname author#1\endcsname
        {\styleoption[\zcnt,2]}%
    \fi
  }%
}
\newcommand\theauthor[1]{\ifcsname author#1\endcsname
  \csname author#1\endcsname\else#1\fi}
\newcommand\addreply[1]{\textCR\textLF\textCR\textLF Reply
  \theauthor{#1}:\textCR\textLF\ignorespaces}
\definestyle{Jim}{color=red,author={Jim Jones}}
\definestyle{Sue}{color=blue,author={Sue Smith}}
\begin{document}
Jim's comment appears here:\pdfcomment[style=Jim]{%
Do I really need a comment here?
\addreply{Sue} 
Yes, Jim, I think you do.
\addreply{Jim} 
Very well, I guess I will leave it here.
}

An now for Sue's turn.\pdfcomment[style=Sue]{%
Jim, can you hear me now?
\addreply{Jim}
I sure can.
\addreply{Sam}
Hey, I'm just interloping into this conversation
}
\end{document}

如下图所示，完整的对话现在发生在一条评论的上下文中。每条回复都以“回复作者姓名：”作为自己的行。如果回复样式未与字段关联，则样式名称本身将用作作者，如第二个对话中author=的情况。Sam

原始答案

这使用一系列水平连接的\pdfsquarecomments 来表示评论/回复链。初始调用是使用

\startcomment[<defaults for comment/reply chain>][<comment options>]{comment}

随后的答复按顺序位于源代码中，如下

\addreply[<comment options>]{comment}

这是 MWE，其中style和Jim已Sue定义。请注意，\addreply选项可以覆盖评论/回复链默认值。评论框的大小/偏移量由定义\mycommentsize，此处设置为.8\baselineskip。标题Reply:通过作者字段添加到回复标题中，如下所示author={\commentmode Jim Jones}

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[rgb]{xcolor}
\usepackage{pdfcomment}
\newlength\myhoffset
\def\mycommentsize{.8\baselineskip}% <--Can be changed
\newcommand\startcomment[1][]{%
  \catcode`_=12
  \gdef\commentdefault{#1}%
  \gdef\commentmode{}%
  \setlength\myhoffset{0pt}%
  \makecommentnext}
\newcommand\addreply{%
  \catcode`_=12
  \gdef\commentmode{Reply: }%
  \addtolength\myhoffset{\mycommentsize}%
  \makecommentnext}
\newcommand\makecommentnext[2][]{%
  \expandafter\pdfsquarecomment\expandafter
    [\commentdefault,hoffset=\myhoffset,
     open=true,opacity=.4,
     height=\mycommentsize,width=\mycommentsize,#1]{#2}%
  \catcode`_=8 }
\definestyle{Jim}{color=red,author={\commentmode Jim Jones}}
\definestyle{Sue}{color=blue,author={\commentmode Sue Smith}}
\begin{document}A comment appears here: 
\startcomment
  [borderstyle=dashed]% Global option for comment/reply chain
  [style={Jim}]
  {Does this require comment?}
\addreply
  [style={Sue},borderstyle=solid]% Can override global default
  {Yes, I think it does.}
\addreply
  [style={Jim}]
  {OK, I will leave it}
And we can contine the line since the comments will appear with opacity so that the underlying text can be read.

$a_b$ shows underscore is restored.
\end{document}
