Biblatex：仅当没有 URL 时才使用 doi

tag-icon • tag-icon biblatex urls doi
Biblatex：仅当没有 URL 时才使用 doi

有没有办法doi仅在缺少URL字段的情况下插入条目的？doi和URL基本上相同，插入它们会产生冗余。我正在biblatex使用biber。

附言：如果您认为这个目标没有意义，请分享您的想法！

答案1

您可以重新定义 bibmacro doi+eprint+url，以便仅当未定义doi该字段时才打印该字段，即在序言中添加以下几行：url

\renewbibmacro*{doi+eprint+url}{%
  \iftoggle{bbx:doi}
    {\iffieldundef{url}{\printfield{doi}}{}}
    {}%
  \newunit\newblock
  \iftoggle{bbx:eprint}
    {\usebibmacro{eprint}}
    {}%
  \newunit\newblock
  \iftoggle{bbx:url}
    {\usebibmacro{url+urldate}}
    {}}

\addbibresource{\jobname.bib}

\renewbibmacro*{doi+eprint+url}{%
  \iftoggle{bbx:doi}
    {\iffieldundef{url}{\printfield{doi}}{}}
    {}%
  \newunit\newblock
  \iftoggle{bbx:eprint}
    {\usebibmacro{eprint}}
    {}%
  \newunit\newblock
  \iftoggle{bbx:url}
    {\usebibmacro{url+urldate}}
    {}}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}

输出：

在此处输入图片描述

如您所见，除字段外，这两个条目完全相同url，如果定义了该字段，doi则不会打印该字段。

答案2

您可以通过数据源映射来实现这一点。\DeclareSourcemap命令

\DeclareSourcemap{
  \maps[datatype=bibtex]{
    \map{
      \step[fieldsource=url,final]
      \step[fieldset=doi,null]
    }  
  }
}

处理任何bibtex输入数据，并对 bibliograhpy 文件中的每个项目执行如下命令\step：

  • 第一步fieldsource检查url字段

    • 该指令final表示如果该字段为空或不存在，则终止当前条目的处理

  • fieldset=doi,null否则执行下一步；这将清除该字段，实际上它使它看起来好像输入中doi从来没有字段。doi

这样做的结果是，所有人biber/biblatex看到的都是一个带有一个url字段或一个doi字段的条目，但不是同时带有这两个字段。

这样做的好处是您不需要知道特定biblatex样式如何选择处理这些字段。
