How can I define and use a new "environment" in Quarto in R?

问题

我正在使用Quarto在RStudio中准备一份文档。输出将是一个LaTeX/PDF文档，文档类别是scrbook。在这本书中，我想每章都以“学习目标”开始。期望的输出如下所示：

  1. ----（在LaTeX中为“hrulefill”）
  2. 学习目标（以粗体字写）
  4. 在本章中，您将学到
  5.  - 主题1
  6.  - 主题2
  7.  - 主题3
  8. ----（在LaTeX中为“hrulefill”）

我想保持这个“学习目标”部分的格式，就像LaTeX类别scrreprt中的“摘要”环境一样（即，左边和右边的间距更大，并且文本的字体不同）。问题是scrbook文档类别中没有定义“摘要”。

我的_quarto.yml文件如下所示：

  1. project:
  2.   type: book
  4. book:
  5.   title: “我的书名”
  6.   author: “Eva”
  7.   date: today
  8.   date-format: DD/MM/YYYY
  9.   #cover-image: cover.jpeg
  10.   chapters:
  11.     - index.qmd
  12.     - part: Basics.qmd
  13.       chapters:
  14.         - chapter_one.qmd
  15.         - chapter_two.qmd
  16.         - chapter_three.qmd
  17.     - part: Intermediate.qmd
  18.       chapters:
  19.         - chapter_four.qmd
  20.         - chapter_five.qmd
  21.         - Conclusion.qmd
  22.     - part: Appendix.qmd
  23.       chapters:
  24.         - Packages.qmd
  25.         - Datasets.qmd
  26.         - Code_Snippets.qmd
  28. #bibliography: references.bib
  29. format:
  30.   html:
  31.     theme: cosmo
  32.   pdf:
  33.     documentclass: scrbook
  34.     colorlinks: true
  35.     toc: true
  36.     toc-title: “目录”
  37.     lot: true
  38.     lof: true
  39.     number-sections: true
  40.     fig-cap-location: bottom
  41.     tbl-cap-location: top
  42.     code-line-numbers: true
  43.     keep-tex: true
  44.     author-meta: “Eva”
  45.     title-meta: “我的书名”
  46.     hyperrefoptions:
  47.     - linktoc=all
  48.     - pdfwindowui
  49.     - pdfpagemode=FullScreen
  50. execute: 
  51.   echo: true
  52.   warning: false
  53.   message: false
  54.   error: false
  55.   cache: true
  56. editor: visual

所以，我有两个问题：

(1) 我如何自定义这样的环境？

(2) 我应该把这段代码放在Quarto的哪里？

英文:

I am preparing a document using Quarto in RStudio. The output will be a LaTeX/PDF document, with the document class scrbook. In this book, I want to start each chapter with "Learning Objectives". The desired output will look like this:

  1. ----("hrulefill" in LaTeX)
  2. Learning Objectives (Written in Bold Font)
  4. In this chapter, you will learn
  5.  - Topic 1
  6.  - Topic 2
  7.  - Topic 3
  8. ---- ("hrulefill" in LaTeX)

I want to keep the formatting of this "Learning Objectives" part like the "abstract" environment in LaTeX class scrreprt (i.e., more space in Left Margin and Right Margin, and a different font for the text). The issue is that "abstract" is not defined for scrbook document class.

My _quarto.yml file looks like the following:

  1. project:
  2.   type: book
  4. book:
  5.   title: "My Book Title"
  6.   author: "Eva"
  7.   date: today
  8.   date-format: DD/MM/YYYY
  9.   #cover-image: cover.jpeg
  10.   chapters:
  11.     - index.qmd
  12.     - part: Basics.qmd
  13.       chapters:
  14.         - chapter_one.qmd
  15.         - chapter_two.qmd
  16.         - chapter_three.qmd
  17.     - part: Intermediate.qmd
  18.       chapters:
  19.         - chapter_four.qmd
  20.         - chapter_five.qmd
  21.         - Conclusion.qmd
  22.     - part: Appendix.qmd
  23.       chapters:
  24.         - Packages.qmd
  25.         - Datasets.qmd
  26.         - Code_Snippets.qmd
  28. #bibliography: references.bib
  29. format:
  30.   html:
  31.     theme: cosmo
  32.   pdf:
  33.     documentclass: scrbook
  34.     colorlinks: true
  35.     toc: true
  36.     toc-title: "Contents"
  37.     lot: true
  38.     lof: true
  39.     number-sections: true
  40.     fig-cap-location: bottom
  41.     tbl-cap-location: top
  42.     code-line-numbers: true
  43.     keep-tex: true
  44.     author-meta: "Eva"
  45.     title-meta: "My Book Title"
  46.     hyperrefoptions:
  47.     - linktoc=all
  48.     - pdfwindowui
  49.     - pdfpagemode=FullScreen
  50. execute: 
  51.   echo: true
  52.   warning: false
  53.   message: false
  54.   error: false
  55.   cache: true
  56. editor: visual

So, I have two questions here:

(1) How can I define such environment myself?

(2) Where should I put this code in Quarto?

从这篇帖子中，你可能可以根据你的喜好进行修改：

  1. format:
  2.   pdf:
  3.     documentclass: scrbook
  4.     include-in-header:
  5.       - text: |
  6.           \providecommand{\abstractname}{学习目标} % 不在scrbook类中
  7.           \newenvironment{secabstract}[1]{%
  8.           \hrule
  9.           \small\textbf{\abstractname：} 
  10.           \newline
  11.           \vspace{0.1cm}
  12.           %\small\emph #1     %  emph接受一个参数
  13.           \small\emph{#1} % 或 \small\textit{#1} 
  14.           \itshape % 如果你想要文本斜体
  15.           }{%
  16.           \newline\hrule
  17.           \vspace{0.6cm}
  18.           }
  20. chapter_one.qmd:
  22. # 介绍
  24. \begin{secabstract}{在这一章中，您将学到}
  25.     
  26.     主题1
  27.     
  28.     主题2
  29.     
  30.     主题3
  31. \end{secabstract}
