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:

----(在LaTeX中为“hrulefill”)
学习目标(以粗体字写)

在本章中,您将学到
 - 主题1
 - 主题2
 - 主题3
----(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:

project:
  type: book

book:
  title: “我的书名”
  author: “Eva”
  date: today
  date-format: DD/MM/YYYY
  #cover-image: cover.jpeg
  chapters:
    - index.qmd
    - part: Basics.qmd
      chapters:
        - chapter_one.qmd
        - chapter_two.qmd
        - chapter_three.qmd
    - part: Intermediate.qmd
      chapters:
        - chapter_four.qmd
        - chapter_five.qmd
        - Conclusion.qmd
    - part: Appendix.qmd
      chapters:
        - Packages.qmd
        - Datasets.qmd
        - Code_Snippets.qmd

#bibliography: references.bib
format:
  html:
    theme: cosmo
  pdf:
    documentclass: scrbook
    colorlinks: true
    toc: true
    toc-title: “目录”
    lot: true
    lof: true
    number-sections: true
    fig-cap-location: bottom
    tbl-cap-location: top
    code-line-numbers: true
    keep-tex: true
    author-meta: “Eva”
    title-meta: “我的书名”
    hyperrefoptions:
    - linktoc=all
    - pdfwindowui
    - pdfpagemode=FullScreen
execute: 
  echo: true
  warning: false
  message: false
  error: false
  cache: true
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:

----("hrulefill" in LaTeX)
Learning Objectives (Written in Bold Font)

In this chapter, you will learn
 - Topic 1
 - Topic 2
 - Topic 3
---- ("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:

project:
  type: book

book:
  title: "My Book Title"
  author: "Eva"
  date: today
  date-format: DD/MM/YYYY
  #cover-image: cover.jpeg
  chapters:
    - index.qmd
    - part: Basics.qmd
      chapters:
        - chapter_one.qmd
        - chapter_two.qmd
        - chapter_three.qmd
    - part: Intermediate.qmd
      chapters:
        - chapter_four.qmd
        - chapter_five.qmd
        - Conclusion.qmd
    - part: Appendix.qmd
      chapters:
        - Packages.qmd
        - Datasets.qmd
        - Code_Snippets.qmd

#bibliography: references.bib
format:
  html:
    theme: cosmo
  pdf:
    documentclass: scrbook
    colorlinks: true
    toc: true
    toc-title: "Contents"
    lot: true
    lof: true
    number-sections: true
    fig-cap-location: bottom
    tbl-cap-location: top
    code-line-numbers: true
    keep-tex: true
    author-meta: "Eva"
    title-meta: "My Book Title"
    hyperrefoptions:
    - linktoc=all
    - pdfwindowui
    - pdfpagemode=FullScreen
execute: 
  echo: true
  warning: false
  message: false
  error: false
  cache: true
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?

  pdf:
    documentclass: scrbook
    include-in-header:
      - text: |
          \providecommand{\abstractname}{学习目标} % 不在scrbook类中
          \newenvironment{secabstract}[1]{%
          \hrule
          \small\textbf{\abstractname:} 
          \newline
          \vspace{0.1cm}
          %\small\emph #1     %  emph接受一个参数
          \small\emph{#1} % 或 \small\textit{#1} 
          \itshape % 如果你想要文本斜体
          }{%
          \newline\hrule
          \vspace{0.6cm}
          }

chapter_one.qmd:

# 介绍
