鼠标悬停在首字母缩略词上可以定义吗？

我的论文中有很多缩写词，我正在使用该acro软件包。我想知道是否有选项可以让论文中的缩写词在鼠标悬停定义上显示，这显然只是 PDF 输出文件的一个有用功能，是否有可能让它们在鼠标悬停在缩写词上时显示长名称？

（固定的）编辑：使用\tooltip宏的问题（固定的）

致 AlexG 我在使用宏时遇到了一个问题\tooltip，即出现以下首字母缩略词重叠的情况：

我不知道为什么或者如何修复它，但它是\tooltip宏的一个本质缺陷，因为当我删除它时它就消失了：请随意尝试这个 MWE：

\begin{document}

The flexibility of fuel cycle use is one of the attractive features presented by \acp{htgr}. Initially \acp{htgr} took advantage of the efficient uranium-thorium fuel cycle which combined \ac{heu} as fissile fuel with fertile thorium that would breed fissile \nuclide[233][92]{U} during operation. With the non-proliferation treaty in force by 1970 a \ac{leu} fuel cycle was designed and adopted to avoid diversion of fissile material.

以下是使用先前定义的命令的示例。需要重新定义包\tooltip中的一些用户宏才能仅插入工具提示Acro后首次使用：

在此处输入图片描述

对于黑色和不可拖动的提示框中的首字母缩略词，请使用

\def\ac#1{\acifused{#1}{\tooltip**[black]{\acs{#1}}{\acl{#1}}}{\acorig{#1}}\relax}
\def\acp#1{\acifused{#1}{\tooltip**[black]{\acsp{#1}}{\aclp{#1}}}{\acporig{#1}}\relax}

代替

\def\ac#1{\acifused{#1}{\tooltip{\acs{#1}}{\acl{#1}}}{\acorig{#1}}\relax}
\def\acp#1{\acifused{#1}{\tooltip{\acsp{#1}}{\aclp{#1}}}{\acporig{#1}}\relax}

答案2

更新2015-09-08：

从 2.1 版开始acro直接支持工具提示。它们可以通过两种方式激活：

  1. 只需设置选项\acsetup{tooltip=true}。这将加载pdfcomment包并用作\pdftooltip创建工具提示的命令。
  2. 将选项设置\acsetup{tooltip-cmd = <macro>}为您喜欢的工具提示创建宏。

作为一般规则，工具提示仅用于短的缩写形式，而长形式则从不。嵌套支持方式如下：禁用“内部”缩写的工具提示，并使用“外部”缩写的工具提示。

可以通过定义宏来直观地检查插入情况

\providecommand\tooltip[2]{[PDF:#1][tooltip:#2]}

并通过 使用它\acsetup{tooltip-cmd = \tooltip}。

在此处输入图片描述

\documentclass{article}

\usepackage{acro}

\providecommand\tooltip[2]{[PDF:#1][tooltip:#2]}
\acsetup{
  tooltip-cmd = \tooltip ,
}

\DeclareAcronym{m}{
  short        = {m},
  long         = {milli},
  short-plural = {},
  long-plural  = {},
  class        = {SI-prefix},
  tooltip      = milli
}

\DeclareAcronym{g}{
  short        = {g},
  long         = {gramm},
  short-plural = {},
  long-plural  = {},
  class        = {SI-unit-derived},
  tooltip      = gramm
}

\DeclareAcronym{mg}{
  short        = {\acs{m}\acs{g}},
  long         = {\Acl{m}\acl{g}},
  short-plural = {},
  long-plural  = {},
  class        = {SI-unit-derived},
}

\begin{document}

\ac{m}\par
\acp{m}\par
\Acp{m}

\bigskip

\ac{mg}\par
\ac{mg}\par
\acf{mg}

\end{document}

原始答案-适用于1.6以下的版本：

以下代码tooltip向首字母缩略词添加了一个属性，允许指定首字母缩略词的悬停文本（如果该文本应与完整格式不同）。如果未指定，则使用完整格式。代码会注意为缩写形式和替代形式插入工具提示，但不是首次使用时不是在首字母缩略词列表中。这是通过重新定义相应的内部命令来实现的。

代码以生成工具提示的pdfcomment包及其\pdftooltip宏为例。\tooltip不过，AlexG 的宏同样易于使用，这意味着集成acro与工具提示生成包/代码无关。下面显示了需要调整的宏。

（我正在考虑添加类似的东西acro……但我首先想得到一些反馈。到目前为止，反馈并不是非常热情……）。

一般用法

\documentclass{article}
\usepackage{pdfcomment}

\usepackage{acro}
\ExplSyntaxOn
...
\ExplSyntaxOff

% long form used as tooltip text:
\DeclareAcronym{cd}{
  short = {CD},
  long  = {Compact Disc}
}
% custom tooltip text:
\DeclareAcronym{mc}{
  short   = {MC},
  long    = {Music Cassette},
  tooltip = {my mouse-over text}
}


\begin{document}

\ac{cd} \ac{mc}\par\vspace{1cm}
\ac{cd} \ac{mc}

\end{document}

在此处输入图片描述

如果应使用另一个工具提示包/代码，则以下代码中的定义

% #1: printed text
% #2: tool tip text
\cs_new_protected:Npn \acro_tooltip:nn #1#2
  { \pdftooltip {#1} {#2} }

必须进行相应调整。

对于 的较新版本acro，以下代码（最初由 Denis Bitouzé 编写）有效：

\documentclass{article}
\usepackage{acro}
\usepackage{pdfcomment}
\usepackage{hyperref}

\DeclareAcronym{cd}{
  short = {CD},
  long  = {Compact Disc}
 }
\DeclareAcronym{mc}{
  short   = {MC},
  long    = {Music Cassette},
  pdfcomment = {my mouse-over text}
}
 
\acsetup{
  pdfcomments/use=true
}

\begin{document}

 \ac{cd} \ac{mc}\par\vspace{1cm}
 \ac{cd} \ac{mc}

 \aca{cd} \aca{mc}

 \acs{cd} \acs{mc}
\end{document}

答案4

从 2.1 版开始，代码可以简化为

\documentclass{article}

\usepackage[tooltip]{acro}

\DeclareAcronym{cd}{
  short = {CD},
  long  = {Compact Disc}
}
\DeclareAcronym{mc}{
  short   = {MC},
  long    = {Music Cassette},
  tooltip = {my mouse-over text}
}


\begin{document}

 \ac{cd} \ac{mc}\par\vspace{1cm}
 \ac{cd} \ac{mc}

 \aca{cd} \aca{mc}

 \acs{cd} \acs{mc}

\end{document}

在这八种情况下我都得到了鼠标悬停。

看256627对于嵌套缩略词的情况。
