使用 Acro 和 Mouse-over 嵌套缩写

我来了克莱门斯来自的解决方案161521用于向 PDF 添加鼠标悬停效果。

它工作得很好，除了我得到嵌套的首字母缩略词时。作为 MWE [编辑：Acro 1.6b 中没有错误/警告 [编辑：使用 Acro 2.0，代码不再起作用。]]：

（对于这个例子，siunitx 或类似的东西可能会有帮助，但这不是这里的重点。）

PDF 文本看起来不错，但鼠标悬停时只显示最后一部分（gramm/byte）。[编辑：在 Linux 上使用 Adob​​e Reader 9.4.2 时，第一次调用时鼠标悬停在前缀上，尽管是小写。第二次调用时仍然没有。[编辑：Windows 7 上的 Adob​​e Acrobat Reader DC 也是如此。不知何故忽略了这一点。] 似乎波普勒几乎是 Linux 上唯一的替代方案。据我猜测不支持工具提示。

老实说，克莱门斯的代码让我难以理解，所以我只是按原样使用它。

答案1

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},
}

答案2

从 2.1 版开始，代码可以简化为

\documentclass{article}

\usepackage[tooltip]{acro}

\DeclareAcronym{B}{
  short        = {B},
  long         = {byte},
  short-plural = {},
  long-plural  = {},
  class        = {non-SI-unit},
}
\DeclareAcronym{g}{
  short        = {g},
  long         = {gramm},
  short-plural = {},
  long-plural  = {},
  class        = {SI-unit-derived},
}
\DeclareAcronym{k}{
  short        = {k},
  long         = {kilo},
  short-plural = {},
  long-plural  = {},
  class        = {SI-prefix},
}
\DeclareAcronym{kB}{
  short        = {\acs{k}\acs{B}},
  long         = {\Acl{k}\acl{B}},
  short-plural = {},
  long-plural  = {},
  class        = {non-SI-unit-derived},
}
\DeclareAcronym{kg}{
  short        = {\acs{k}\acs{g}},
  long         = {\Acl{k}\acl{g}},
  short-plural = {},
  long-plural  = {},
  class        = {SI-unit},
}
\DeclareAcronym{m}{
  short        = {m},
  long         = {milli},
  short-plural = {},
  long-plural  = {},
  class        = {SI-prefix},
}
\DeclareAcronym{mg}{
  short        = {\acs{m}\acs{g}},
  long         = {\Acl{m}\acl{g}},
  short-plural = {},
  long-plural  = {},
  class        = {SI-unit-derived},
}


\begin{document}

 1~\Ac{g}
 1~\Ac{B}

 1~\ac{mg}
 1~\ac{kg}
 1~\ac{kB}

 2~\Acp{g}
 2~\Acp{B}

 2~\acp{mg}
 2~\acp{kg}
 2~\acp{kB}

\end{document}

现在我得到了鼠标悬停（在 Windows 7 上的 Acrobat Reader 15.008.20082 中），但它们显示的是缩写形式（mg、kg、kB）。

它在非嵌套情况下有效（语法、字节）。
