使用 Biblatex-chicago 的 DMY 日期和连续逗号

Question 1

还有一种无需切换语言的方法australian, 但我认为 , 如果您的文件实际上是如此 , 那这并不是最好的主意american.

您只需将以下代码块放入序言中即可biblatex更改日期格式。american

您可以在中找到定义australia.lbx，其他日期格式均继承自british.lbx。只需从那里复制相关定义即可（相关定义包括\mkbibdatelong、\mkbibdateshort，如果也使用\mkbibordinal）。

\DefineBibliographyExtras{american}{%
  \protected\def\mkbibdateshort#1#2#3{%
    \iffieldundef{#3}
      {}
      {\mkdayzeros{\thefield{#3}}%
       \iffieldundef{#2}{}{/}}%
    \iffieldundef{#2}
      {}
      {\mkmonthzeros{\thefield{#2}}%
       \iffieldundef{#1}{}{/}}%
    \iffieldbibstring{#1}
      {\bibstring{\thefield{#1}}}
      {\dateeraprintpre{#1}\mkyearzeros{\thefield{#1}}}}%
  \protected\def\mkbibdatelong#1#2#3{%
    \iffieldundef{#3}
      {}
      {\stripzeros{\thefield{#3}}%
       \iffieldundef{#2}{}{\nobreakspace}}%
    \iffieldundef{#2}
      {}
      {\mkbibmonth{\thefield{#2}}%
       \iffieldundef{#1}{}{\space}}%
    \iffieldbibstring{#1}{\bibstring{\thefield{#1}}}{\stripzeros{\thefield{#1}}}}%
}

如果你打算更频繁地使用这种日期格式，一个更biblatex简单的方法是创建一个新的本地化文件，american-dmy.lbx其内容如下

\ProvidesFile{american-dmy.lbx}[american localisation with dmydate format for long dates]

\InheritBibliographyExtras{american}
\DeclareBibliographyExtras{%
  \protected\def\mkbibdateshort#1#2#3{%
    \iffieldundef{#3}
      {}
      {\mkdayzeros{\thefield{#3}}%
       \iffieldundef{#2}{}{/}}%
    \iffieldundef{#2}
      {}
      {\mkmonthzeros{\thefield{#2}}%
       \iffieldundef{#1}{}{/}}%
    \iffieldbibstring{#1}
      {\bibstring{\thefield{#1}}}
      {\dateeraprintpre{#1}\mkyearzeros{\thefield{#1}}}}%
  \protected\def\mkbibdatelong#1#2#3{%
    \iffieldundef{#3}
      {}
      {\stripzeros{\thefield{#3}}%
       \iffieldundef{#2}{}{\nobreakspace}}%
    \iffieldundef{#2}
      {}
      {\mkbibmonth{\thefield{#2}}%
       \iffieldundef{#1}{}{\space}}%
    \iffieldbibstring{#1}{\bibstring{\thefield{#1}}}{\stripzeros{\thefield{#1}}}}%
}
\InheritBibliographyStrings{american}
\endinput

并通过加载此语言配置

\DeclareLanguageMapping{american}{american-dmy}

第二种解决方案的完全独立的 MWE（如果您在文档中使用它，您将拥有该.bib文件，并且american-dmy.lbxLaTeX 可以在某个地方找到它，当然可以省略filecontents）

\documentclass{article}
\usepackage[american]{babel}
\usepackage[authordate-trad, backend=biber, dateabbrev=true, firstinits=true, maxcitenames=3, isbn=false, doi=false, eprint=false]{biblatex-chicago}
\DeclareLanguageMapping{american}{american-dmy}

\begin{filecontents}{american-dmy.lbx}
\ProvidesFile{american-dmy.lbx}[american localisation with dmydate format for long dates]

\InheritBibliographyExtras{american}
\DeclareBibliographyExtras{%
  \protected\def\mkbibdateshort#1#2#3{%
    \iffieldundef{#3}
      {}
      {\mkdayzeros{\thefield{#3}}%
       \iffieldundef{#2}{}{/}}%
    \iffieldundef{#2}
      {}
      {\mkmonthzeros{\thefield{#2}}%
       \iffieldundef{#1}{}{/}}%
    \iffieldbibstring{#1}
      {\bibstring{\thefield{#1}}}
      {\dateeraprintpre{#1}\mkyearzeros{\thefield{#1}}}}%
  \protected\def\mkbibdatelong#1#2#3{%
    \iffieldundef{#3}
      {}
      {\stripzeros{\thefield{#3}}%
       \iffieldundef{#2}{}{\nobreakspace}}%
    \iffieldundef{#2}
      {}
      {\mkbibmonth{\thefield{#2}}%
       \iffieldundef{#1}{}{\space}}%
    \iffieldbibstring{#1}{\bibstring{\thefield{#1}}}{\stripzeros{\thefield{#1}}}}%
}
\InheritBibliographyStrings{american}
\endinput
\end{filecontents}

在此处输入图片描述

还要注意，最好使用大写，因为单词出现在句中而不是句首（“请注意，所有表达都应大写，因为它们通常在句中使用。当需要在句首使用时，软件包biblatex会自动将第一个单词大写。用于标题的表达方式应以适合标题的方式大写”biblatex文档 v. 2.8，§3.8“本地化命令”，第 90 页。我将其更改available = {Available at},为available = {available at},。）还biblatex已为 URL（称为url）和urlseen访问 URL 的日期提供了本地化字符串，因此您可以使用这些字符串，而不必声明新的字符串。
