从 biblatex 中索引的另一个字段获取名称

从 biblatex 中索引的另一个字段获取名称

author这是将放入索引而不是 的解决方案shortauthor：使用 shortauthor 和 biblatex 让作者显示在索引中

但我想对此进行扩展，并为索引中应出现的值设置一个特殊字段。包authorindex建议为此字段authauthor（真实作者）设置。目标是为“Elisabet Engdahl”设置一个索引条目，而不是两个：

在此处输入图片描述

因此第二个条目不应该存在。

这是我想出的办法，但它似乎忽略了我的authauthor领域：

\documentclass[english]{scrartcl}

\begin{filecontents}{\jobname.bib}

        authautor = {Frey, Werner and Tappe, Hans Thilo},
        Title = {{Zur Interpretation der X-bar-Theorie und zur Syntax des Mittelfeldes}},

authauthor是一个名单，所以你不能使用\iffieldundef你需要使用\ifnameundef

\renewbibmacro*{citeindex}{%
  \ifciteindex
    {\iffieldequalstr{labelnamesource}{shortauthor}
      {\ifnameundef{authauthor}
        {\indexnames{author}}
        {\indexnames{authauthor}}}
      {\iffieldequalstr{labelnamesource}{author}
        {\ifnameundef{authauthor}% if defined use authauthor
          {\indexnames{author}}
          {\indexnames{authauthor}}} % if defined use this field 
        {\iffieldequalstr{labelnamesource}{shorteditor}
          {\ifnameundef{autheditor}
            {\indexnames{editor}}
            {\indexnames{autheditor}}}
          {\indexnames{labelname}}}}}
    {}}

autheditor如果你想使用它，你还需要声明

\begin{filecontents}{authauthor.dbx}
\DeclareDatamodelFields[type=list, datatype=name]{
 authauthor,
 autheditor}
\DeclareDatamodelEntryfields{authauthor,autheditor}
\end{filecontents}
