Scoping of `setspace` classoption

[johnghill]

Prerequisites

• Run quarto --version and report the Quarto version you are using: 1.0.36
• Tell us your OS: 5.15.74-3-MANJARO x86_64

Having trouble rendering to PDF?

• Tell us how you are rendering Quarto docs (RStudio, VS Code, command line, etc): Rstudio terminal quarto render
• Tell us what TeX and version you are using tex --version: TeX 3.141592653 (TeX Live 2022/Arch Linux)
• Are you using tinytex (note tinytex is a version of TeX Live)?: tinytex 0.42 library not in use

Description

Alternative classoptions for line spacing have the effect of increasing all spacing, including of front matter, tables and code chunks (see Table 1.1 of the rendered A-doctoral-thesis-title.pdf file.

Steps to Reproduce

1. Edit ./_extensions/quarto-thesis/_extension.yml
2. Change classoption from singlespacing to either onehalfspacing or doublespacing
3. quarto render to render PDF

Additional Information

Shouldn't user alterations to setspace be confined in their scope to paragraph text within the main body? Relevant Stack Overflow discussions here, here, and here

Adding the following to ./_quarto.yml protects single line spacing within code (shaded environment) and tabular environments. I'm not sure if all of these tabular environments are relevant : in my test (with keep-tex: true) Table 1.1 was located within a longtable environment.

format:
  quarto-thesis-pdf: 
    urlcolor: red
    toclinkcolor: black
    toc-depth: 2
    classoption: [onehalfspacing, oneside]
    header-includes: |
      \usepackage{etoolbox}
      \AtBeginEnvironment{Shaded}{\singlespace}
      \AtBeginEnvironment{tabular}{\singlespacing}
      \AtBeginEnvironment{lltable}{\singlespacing}
      \AtBeginEnvironment{longtable}{\singlespacing}
      \AtBeginEnvironment{tablenotes}{\doublespacing}
      \captionsetup[table]{font={stretch=1.5}}
      \captionsetup[figure]{font={stretch=1.5}}

Thanks for the comment and solution(!) The scoping of setspace, I assume is being set with the cls file (MastersDoctoralThesis.cls). While I could add those lines to the cls file, I think taking control of the spacing as you did by adding some lines to the header is a better approach.

I'll add your solution to the FAQs so if others have the same questions they can find a solution.
