在颜色切换命令中使用空行的问题

在颜色切换命令中使用空行的问题

这是对我的问题的跟进更改文档部分的颜色系统?

我尝试通过将文档定义为蓝色(或我想要的任何颜色)来解决此问题,然后将颜色切换回适合我特定环境的正常颜色,然后再切换回来。从示例中可以更清楚地看出这一点。但是,我的问题不是颜色切换,它运行完美。

我的问题是我不能在新命令中使用任何空行!

例如

\iSol{ \lipsum[75] } 

运行完美,但是,

\iSol{ \lipsum[75]

\lipsum[66] }

抱怨缺少par。有什么想法可以修复命令以便我可以在其中使用空行吗?

虽然LaTeX2e \newcommand默认情况下会创建\long宏(而带星号的版本会创建短宏),但\DeclareDocumentCommand情况恰恰相反。为了允许在宏参数中使用段落,您必须在说明符前加上+, (在您的例子中):

\DeclareDocumentCommand{\iSol}{+m G{}}{% <-- don't forget this
  \iftoggle{isLF}{% <-- don't forget this
      \UNIfullcolor{#1}% <-- don't forget this
  }{#2}% <-- don't forget this
}

请注意,这\DeclareDocumentCommandxparse的版本\def,因此它不会检查宏是否存在。\NewDocumentCommand是更安全的版本。
