将特定参考书目字段设置为斜体和单倍行距

Question

我正在尝试使用

\ExecuteBibliographyOptions

使 [附录] 字段同时为斜体和单倍行距。但是，{font=textit} 和 {space=double}/{spacing=double}/{space=doublespace}/{spacing=doublespace} 似乎不起作用。

对于斜体和单倍行距，正确的“键”和“值”格式是什么？

当前代码：

\usepackage[doublespacing]{setspace}
\usepackage[backend=biber,
style=authoryear,
maxbibnames=99
]{biblatex}
\addbibresource{Phi-Features and Animacy.bib}
\DeclareCiteCommand{\citeyear}
    {}
    {\bibhyperref{\printdate}}
    {\multicitedelim}
    {}
\ExecuteBibliographyOptions[addendum]{?????}

移动网络

\documentclass[12pt, letterpaper]{article}
\usepackage[document]{ragged2e}
\usepackage{fullpage}
\usepackage[margin=1in]{geometry}
\usepackage[doublespacing]{setspace}

\setlength{\parindent}{.5in}

\usepackage{filecontents}

\usepackage[doublespacing]{setspace}
\usepackage[backend=biber,
style=authoryear,
maxbibnames=99
]{biblatex}
\addbibresource{asdfggg.bib}
\ExecuteBibliographyOptions[addendum]{}
\DeclareFieldFormat{addendum}{\textit{#1}}
\DeclareCiteCommand{\citeyear}
    {}
    {\bibhyperref{\printdate}}
    {\multicitedelim}
    {}
    
\begin{filecontents}{asdfggg.bib}
@thesis{codename,
author = {Name Surname},
title = {Title: A Subtitle},
type = {Doctoral Dissertation},
institution = {University of Asdfg},
year = {3333},
location = {Location},
addendum = {\linebreak This is my annotation.}
}
\end{filecontents}

\begin{document}
\pagenumbering{arabic}
\nocite{*}
\uspunctuation
\printbibliography[
heading=bibintoc,
title={Annotated Bibliography}
]

\end{document}

对我来说似乎都\DeclareFieldFormat不起作用。\ExecuteBibliographyOptions

并非所有的biblatex自定义功能都可用作键值选项。特别是字段格式几乎完全通过 处理\DeclareFieldFormat，它不使用键值语法，而是像普通的宏定义一样工作（我们可以理解\DeclareFieldFormat{<field>}{<code with #1>}为定义一个辅助宏，然后将其应用为\<helper macro>{<field contents>}）。

您已经使用了\textit斜体addendum，所以我们只需要添加一个命令或环境来提供单倍行距。由于您正在加载解决方案，因此setspace解决方案可能看起来像

\DeclareFieldFormat{addendum}{%
  \begin{singlespace}
    \itshape #1%
  \end{singlespace}%
  \nopunct}

总共

\documentclass[12pt, letterpaper]{article}
\usepackage[document]{ragged2e}
\usepackage[margin=1in]{geometry}
\usepackage[doublespacing]{setspace}

\setlength{\parindent}{.5in}

\usepackage[backend=biber,
  style=authoryear,
  maxbibnames=99
]{biblatex}

\DeclareFieldFormat{addendum}{%
  \begin{singlespace}
    \itshape #1%
  \end{singlespace}%
  \nopunct}

\usepackage{lipsum}
    
\begin{filecontents}{\jobname.bib}
@thesis{codename,
  author      = {Name Surname},
  title       = {Title},
  subtitle    = {A Subtitle},
  type        = {phdthesis},
  institution = {University of Asdfg},
  year        = {3333},
  location    = {Location},
  addendum    = {This is my annotation. \lipsum},
}
\end{filecontents}
\addbibresource{\jobname.bib}

\begin{document}
\nocite{*}
\uspunctuation
\printbibliography[
  heading=bibintoc,
  title={Annotated Bibliography}
]

\end{document}
