![将 todonotes 与 mdframed 结合使用,突出显示段落并撰写笔记](https://linux22.com/image/300909/%E5%B0%86%20todonotes%20%E4%B8%8E%20mdframed%20%E7%BB%93%E5%90%88%E4%BD%BF%E7%94%A8%EF%BC%8C%E7%AA%81%E5%87%BA%E6%98%BE%E7%A4%BA%E6%AE%B5%E8%90%BD%E5%B9%B6%E6%92%B0%E5%86%99%E7%AC%94%E8%AE%B0.png)
我正在尝试结合todonotes
使用mdframed
以创建一个统一的命令,允许同时编写待办事项和突出显示段落。语法是\todo[<todo-options>]{<todonote>}<paragraph>
,其中基本上所有参数都是可选的(因此可以使用\todo{<todonote>}
,\todo<paragraph>
或两者一起使用)。
我认为我已经使用下面的代码完成了大部分工作,但存在两个问题:
当同时使用
\todo
和mdframed
环境时,会出现一个空行,我需要手动用 '删除'\vspace{-1\baselineskip}
。这会产生不良副作用,即这两个行号重叠。我该如何避免出现这个空行?由于这个问题,的定义
\todo
感觉效率低下,因为我需要两个环境实例mdframed
,一个有\vspace{}
,一个没有。
我的解决方案如何改进?

答案1
我不太清楚为什么会出现换行符。这肯定是 todonotes 和 lineno 包之间不兼容造成的。您用来\vspace
修复此问题的 hack 可能和其他方法一样好。
修复不正确的行号的一种方法是“手动”减少 lineno 包使用的计数器。您可以更有效地编写代码,以避免环境notes
出现两次:
\DeclareDocumentCommand{\todo}{ O{} +g +d<> }{%
\IfNoValueF{#2}{%
\oldtodo[caption={#2},size=\footnotesize,#1]{\sffamily#2}%
}%
\IfNoValueF{#3}{%
\IfNoValueF{#2}{ \vspace{-1\baselineskip} }% remove unwanted linebreak
\begin{note}%
\internallinenumbers%
\IfNoValueF{#2}{% fix line numbers when todo+note
\ifLineNumbers\addtocounter{runninglinenumber}{-1}\fi%
}%
\indent%
#3%
\end{note}%
}
}%
虽然我并不认为这是一个优雅的解决方案,但它似乎解决了你的问题:
请注意,我使用了\IfNoValueF
而不是\IfNoValueTF
,因为您只关心有值的情况,而我使用了\internallinenumbers
而不是环境,因为无需在您的notes
环境中启动第二个环境。\ifLineNumbers
对于您的 MWE 来说,这是多余的,因为它只是 lineno 包用来查看行号是否打开的开关,但如果您打算打开和关闭行号,您可能需要它。最后,正如您所猜测的,runninglinenumber
是 lineno 用于运行行号的计数器。
