emph 的缩写版本？

有没有类似 的简短版本\emph？我想要的是与\lstShortInline或shortvrb提供的内容相当的东西，只是不是针对\verb命令而是针对\emph命令。

例如，而不是This is an \emph{important} test.，我想写This is an |important| test.或类似的东西。

答案1

\documentclass{article}
\catcode`\|=13 % make | active
\def|#1|{\emph{#1}}
\begin{document}
This is an \emph{important} test.
This is an |important| test.
\end{document}

答案2

你可以这样做：

\catcode`\|=\active
\def|#1|{\emph{#1}}

然后您就可以|text|像使用一样使用\emph{text}。

答案3

到目前为止给出的所有答案都捕获了一个论点，从而永久固定了论点标记的类别代码。如果您希望逐字文本与强调文本混合，这将不起作用。它们也不是\protected，因此它们在标题或脚注中不起作用。

以下用途|+ ...文本... +|分隔强调的文本，适用于我刚刚描述的情况（同时满足您的原始要求）。我发现使用“ |+”和“ +|”之类的快捷方式更好，因为它允许您轻松地将“ |”插入文档中。否则，您需要编写一些代表“ |”原始含义的控制序列。
