我想在新章节后缩进第一段，但我不想缩进新行....我知道 indentfirst 和 parskip 包，但它们不能一起使用！我想结合两者的功能，但 parskip 会覆盖 indentfirst....
先感谢您！
这是一个代码示例：
\documentclass[a4paper, oneside]{report}
\usepackage{indentfirst}
\begin{document}
%This is going to indent (ok):
This life, which had been the tomb of his virtue and of his honour, is but a walking shadow; a poor player, that struts and frets his hour upon the stage, and then is heard no more: it is a tale told by an idiot, full of sound and fury, signifying nothing.
%This is going to indent (bad):
This life, which had been the tomb of his virtue and of his honour, is but a walking shadow; a poor player, that struts and frets his hour upon the stage, and then is heard no more: it is a tale told by an idiot, full of sound and fury, signifying nothing.
\end{document}
\documentclass[a4paper, oneside]{report}
\usepackage{parskip}
\begin{document}
%This is not going to indent (bad):
This life, which had been the tomb of his virtue and of his honour, is but a walking shadow; a poor player, that struts and frets his hour upon the stage, and then is heard no more: it is a tale told by an idiot, full of sound and fury, signifying nothing.

答案1
背景
在通常的印刷实践中，通常会区分经典段落：通常使用缩进来区分彼此.还有现代段落：取消缩进，而是在段落之间用空行来区分。
当然，还有其他类型的段落，但并不那么流行，了解上述两种段落之间的区别就足够了。没有哪种段落比另一种更好，但事实是，无论你决定使用哪种段落，你都需要保持一致，不要混淆它们。
正文通常LaTeX以经典的段落形式撰写，除非序言另有说明。
现在说到缩进，缩进是一种视觉标记，用于显示一个段落的结束和另一个段落的开始。但是，如果后面的空白足以让读者明白这是一个新段落，而不是前一个段落的延续，那么缩进在开头段落中是多余的，有时在一些浮动对象之后也是多余的。就像您要求的那样。
原因
规则很简单：无论标题是什么，都不要紧跟在段落后面缩进段落。
因为它是多余的，不必要的。标题本身就告诉你然后开始一个新段落，因此出血是多余的。
有时我会删除其他位置的缩进，例如在用于撰写法律页面的小页面中。
关于使用包自动执行此任务，了解这一点很有趣，我很久以前做过非常浅显的测试，但并不满意。
简而言之
您所要求的内容在 中是可以实现的LaTeX，但不建议这样做。出版业已有 500 多年的传统，其所体现的某些准则并非出于一时兴起或少数人强加，而是经过时间考验的合理性和实用性。
换句话说，不要缩进标题后的第一行，没有必要这样做，也没有理由为了可读性而这样做，这应该是可以这样做的原因。讽刺的是，这才是最受影响的。
问候。
答案2
虽然我认为 Aradnix 在概念层面上所说的话完全正确（你不应该使用你所要求的东西），但我会给你另一种实现它的可能性。
我扩展了 skpblack 的答案，并将其附加\ind到\section，这样就不必手动调用它了。我使用了 Werner 的答案如何将代码附加到某个部分？去做这个。
代码
\documentclass[a4paper, oneside]{report}
\newlength{\oldparindent}
\setlength{\oldparindent}{\parindent} % Save \parindent before of change
\setlength{\parskip}{0.5\baselineskip \advance\parskip by 0pt plus 2pt} % Definition of `parskip`
\setlength{\parindent}{0pt}
\newcommand{\ind}{\hspace*{\oldparindent}} % Command to indent manually
\usepackage{etoolbox}
\makeatletter
\patchcmd{\@xsect} % <cmd>
{\ignorespaces} % <search>
{\ind} % <replace>
{}{} % <success><failure>
\makeatother
\begin{document}
\section{First}
This life, which had been the tomb of his virtue and of his honour, is but a walking shadow; a poor player, that struts and frets his hour upon the stage, and then is heard no more: it is a tale told by an idiot, full of sound and fury, signifying nothing.

建议
正如我所说：遵循 Aradnix 的描述并避免这种奇怪的缩进方式。当我开始使用 LaTeX 时，我必须学习的一条规则是，只有当我有合理且正当的理由时才更改其默认值。我看不出有任何理由去做你想做的事。或者你看得出来？
答案3
由于您只想缩进该部分的开头，我认为手动执行此操作更容易（因为它根本不是段落），因此我为其创建了一个新命令\ind（类似于\indent但它可以与 一起使用\oldparindent）并复制帕斯基普在更改它之前保存\parindent（在）。\oldparindent
这是我的代码
\documentclass[a4paper, oneside]{report}
\newlength{\oldparindent}
\setlength{\oldparindent}{\parindent} % Save \parindent before of change
\setlength{\parskip}{0.5\baselineskip \advance\parskip by 0pt plus 2pt} % Definition of `parskip`
\setlength{\parindent}{0pt}
\newcommand{\ind}{\hspace*{\oldparindent}} %Command to indent manually
\begin{document}
\section{First}
\ind This life, which had been the tomb of his virtue and of his honour, is but a walking shadow; a poor player, that struts and frets his hour upon the stage, and then is heard no more: it is a tale told by an idiot, full of sound and fury, signifying nothing.
This life, which had been the tomb of his virtue and of his honour, is but a walking shadow; a poor player, that struts and frets his hour upon the stage, and then is heard no more: it is a tale told by an idiot, full of sound and fury, signifying nothing.
\end{document}
因此您应该做的是\ind在每个 后面添加\section{}。
