使用 Biblatex 和 APA 样式来格式化澳大利亚日期？

Question

在我的参考文献中，我希望我的日期写成“日月年”。我按照此处的最佳答案实现了这一点使用 biblatex 格式化日期“日月年”。但是，当我尝试使用带有 style=apa 的 MWE 时，我在 \printbibliography 命令中收到错误“未定义的控制序列。\end”。

\documentclass{article}

\usepackage[australian,american]{babel}

\usepackage[style=apa, backend=biber, dateabbrev=false]{biblatex}

\begin{filecontents}{references.bib}
@book{Book,
  title = {This is a Title},
  author = {Author, Some},
  location = {The City},
  publisher = {Publisher},
  date = 2005,
  month = feb,
  day = 14,
}
\end{filecontents}
\addbibresource{references.bib}

\begin{document}
\today

Citing \cite{Book}.

\begin{otherlanguage}{australian}
\printbibliography
\end{otherlanguage}

\end{document}

Answer 1

你的序言中的以下重新定义应该足够了

\DefineBibliographyExtras{american}{%
  \protected\def\mkbibdateapalongmdy#1#2#3{%
    \iffieldundef{#3}
      {}
      {\mkbibordinal{\thefield{#3}}%
       \iffieldundef{#2}{}{\nobreakspace}}%
    \iffieldundef{#2}
      {}
      {\mkbibmonth{\thefield{#2}}%
       \iffieldundef{#1}{}{\space}}%
    \iffieldbibstring{#1}{\bibstring{\thefield{#1}}}{\stripzeros{\thefield{#1}}}}}

但由于当前版本在文件中biblatex-apa使用了\DefineBibliographyExtras而不是 ，因此不太适用。此错误\DeclareBibliographyExtras.lbx已经在 github 存储库中解决，但它尚未进入 CTAN。

作为临时解决方法，我建议您创建一个名为的新文件american-bpb.lbx并填充

\ProvidesFile{american-bpb.lbx}[2015/10/10\space v6.7\space APA biblatex localisation - modified]
\InheritBibliographyExtras{american-apa}

\DeclareBibliographyStrings{inherit = {american-apa}}

\DefineBibliographyExtras{american}{%
  \protected\def\mkbibdateapalongmdy#1#2#3{%
    \iffieldundef{#3}
      {}
      {\mkbibordinal{\thefield{#3}}%
       \iffieldundef{#2}{}{\nobreakspace}}%
    \iffieldundef{#2}
      {}
      {\mkbibmonth{\thefield{#2}}%
       \iffieldundef{#1}{}{\space}}%
    \iffieldbibstring{#1}{\bibstring{\thefield{#1}}}{\stripzeros{\thefield{#1}}}}}

\endinput

在您的文档中使用\DeclareLanguageMapping{american}{american-bpb}（而不是通常需要的\DeclareLanguageMapping{american}{american-apa}）

在 MWE 中我们创建了american-bpb.lbxviafilecontents

\documentclass{article}
\usepackage{filecontents}
\usepackage[american]{babel}

\begin{filecontents}{american-bpb.lbx}
\ProvidesFile{american-bpb.lbx}[2015/10/10\space v6.7\space APA biblatex localisation - modified]
\InheritBibliographyExtras{american-apa}

\DeclareBibliographyStrings{inherit = {american-apa}}

\DefineBibliographyExtras{american}{%
  \protected\def\mkbibdateapalongmdy#1#2#3{%
    \iffieldundef{#3}
      {}
      {\mkbibordinal{\thefield{#3}}%
       \iffieldundef{#2}{}{\nobreakspace}}%
    \iffieldundef{#2}
      {}
      {\mkbibmonth{\thefield{#2}}%
       \iffieldundef{#1}{}{\space}}%
    \iffieldbibstring{#1}{\bibstring{\thefield{#1}}}{\stripzeros{\thefield{#1}}}}}

\endinput
\end{filecontents}


\usepackage[style=apa, backend=biber, dateabbrev=false]{biblatex}
\DeclareLanguageMapping{american}{american-bpb}

\begin{filecontents}{\jobname.bib}
@online{online,
  title = {Something on the Internet},
  author = {Anne Uthor},
  date = {2015-04-08},  
  url = {http://www.example.com},
  urldate = {2015-08-04},  
}
\end{filecontents}
\addbibresource{\jobname.bib}

\begin{document}
\nocite{*}
\printbibliography
\end{document}
