我试图在引文中仅显示作者名字的首字母。因此，我应该得到以下格式：(J. Kennedy et al., 2023)，而不是 (John Fitzgerald Kennedy et al., 2023)。
在 LaTeX 中可以使用 Biblatex 来解决这个问题。但是，代码（来自这里）用于解决这个问题是旧的，并且不使用Biblatex 3.3 命名约定。
当我运行以下 MWE 时，出现以下错误：
Illegal parameter number in definition of \blx@defformat@d.
<to be read again>

l.23 \usebibmacro{name:first-last}{#1}{#4
}{#5}{#7}%

对此的传统解决方案是：
\documentclass[]{article}
\usepackage{filecontents}
\begin{filecontents*}{bib.bib}
@article{jdoe,
author = {John Paul Peter Julian Doe},
journal = {Journal},
title = {Title},
year = 2014,
pages = 111--222,
}
\end{filecontents*}
\usepackage[style=authoryear]{biblatex}
\addbibresource{bib.bib}
% Helper function to get initial letter
\def\firstinit#1{\justfirst#1\relax}
\def\justfirst#1#2\relax{#1}
% Format for FirstInitials - LastName (standard implementation)
\DeclareNameFormat{firstinits-last}{%
\usebibmacro{name:first-last}{#1}{#4}{#5}{#7}%
\usebibmacro{name:andothers}}
% Format for VeryFirstInitial - LastName
\DeclareNameFormat{firstfirstinit-last}{%
\usebibmacro{name:first-last}{#1}{\firstinit{#4}\adddot}{#5}{#7}%
\usebibmacro{name:andothers}}
% Set format for sortname (bibliography) and labelname (citation)
\DeclareNameAlias{sortname}{firstinits-last}
\DeclareNameAlias{labelname}{firstfirstinit-last}
\begin{document}
\noindent Citation: \cite{jdoe}.
\printbibliography[]
\end{document}
有人能帮助我使用新的代码来调整这个遗留代码吗？Biblatex 3.3命名约定？
答案1
如今，我将使用 的biblatex扩展名称格式（例如，参见仅使用姓氏作为 namepartfamily，而不是前缀后的所有内容，如何输入有姓氏和初级部分但没有名字的作者姓名？，Bibtex/Biber：如何使用埃塞俄比亚惯例引用作者？）并明确给出首字母
\documentclass{article}
\usepackage[style=authoryear, giveninits=true,]{biblatex}
\DeclareNameAlias{labelname}{given-family}
\begin{filecontents*}{\jobname.bib}
@article{jdoe,
author = {family=Doe, given={John Paul Peter Julian}, given-i={J}},
journal = {Journal},
title = {Title},
year = 2014,
pages = {111--222},
}
\end{filecontents*}
\addbibresource{\jobname.bib}
\begin{document}
\noindent Citation: \cite{jdoe}.
\printbibliography
\end{document}
如果你想坚持使用宏解决方案（对于非 ASCII 字符和其他输入，它可能会严重失效），请尝试
\documentclass{article}
\usepackage[style=authoryear]{biblatex}
\def\firstinit#1{\justfirst#1\relax}
\def\justfirst#1#2\relax{#1}
\renewcommand*{\mkbibnamegiven}[1]{%
\expandafter\firstinit\expandafter{#1}\bibinitperiod}
\DeclareNameAlias{labelname}{given-family}
\begin{filecontents*}{\jobname.bib}
@article{jdoe,
author = {John Paul Peter Julian Doe},
journal = {Journal},
title = {Title},
year = 2014,
pages = {111--222},
}
\end{filecontents*}
\addbibresource{\jobname.bib}
\begin{document}
\noindent Citation: \cite{jdoe}.
\printbibliography
\end{document}
在 MWE 中得到相同的结果。
