csquotes - 如何根据 titlecase 删除“引号”环境的缩进

Question

我是一位非常满意的用户csquotes。下面是使用显示模式的引号的 mwe。

\documentclass{article}
\usepackage[threshold=0]{csquotes}
  \MakeBlockQuote{<}{|}{>}
  \SetBlockEnvironment{quotation}

\begin{document}

<This is a text written in display mode, with the first letter in uppercase.

This is the second paragraph.>

\begin{displayquote}
\noindent this is a text written in display mode, with the first letter in lowercase.

This is the second paragraph.
\end{displayquote}

\end{document}

我希望在所有显示模式引号（block[c]quote; display[c]quote; 活动字符）中，第一段的缩进将被自动删除（因此无需使用，例如\noindent），在以下情况下文本首字母小写。

Answer 1

我认为这非常符合该quoting包的用例。它不是通过检查首字母的大小写来工作的，而是通过检查引文前是否有段落分隔符来工作的。这是很好的标记，如果你以小写字母开头，那么它是同一个段落，所以你不会中断。在这种情况下，环境quoting不会缩进引文的第一行。如果你在它之前引入一个段落分隔符，它就会缩进。

\documentclass{article}

\usepackage{quoting}
\usepackage[threshold=0]{csquotes}
  \MakeBlockQuote{<}{|}{>}
  \SetBlockEnvironment{quoting}

\begin{document}

The next quote starts with an uppercase letter because it is a new paragraph,
so we break a paragraph before it, and it will start indented:

<This is a text written in display mode, with the first letter in uppercase.

This is the second paragraph.>

The next quotation is a continuation of this sentence (and thus paragraph), so
we make no paragraph break before it. It starts without indentation:
\begin{displayquote}
this is a text written in display mode, with the first letter in lowercase.

This is the second paragraph.
\end{displayquote}

\end{document}
