当缺少名字时，在 biblatex 中缩写名称

Question

这是对使用 biblatex 防止匿名作品名称缩写，本身就是在 biblatex 中缩写解决作者名字的缩写。

简而言之，我需要打印出作者在其原创作品中出现的名字。.bib另一方面，在我的文件中，我总是在括号内提供缺少的姓名信息。因此，诀窍是以适当的方式删除这些额外信息。

现在，使用 Andrew Swann 的代码回答对于我的问题，我注意到，当我的.bib文件中有一个条目缺少作者的名字，但在括号中提供时，输出会打印作者的姓氏，后跟逗号加空格加句点，因为代码将名字缩写为空格字符：

Lennon, . (1974)。

适当的输出将是仅打印姓氏：Lennon (1974)。其他姓名应按照此 MWE 中的方式显示。

有什么建议么？

Answer 1

这些正则表达式技巧可能非常复杂，并且这里的解决方案也可能有其缺点，但是这里......

\DeclareSourcemap{
  \maps[datatype = bibtex]{
    \map{
      \step[fieldsource = author, match = \regexp{\A\[(.+)\s+([^\s]+)\]\Z}, replace = {[$2, $1]}]
    }
    \map{
      \step[fieldsource = author, match = \regexp{(\w+)\[(.+?)\]}, replace ={$1.}]
    }
    \map{
      \step[fieldsource = author, notmatch = \regexp{\A\[(.+)\]\Z}, final]
      \step[fieldsource = author, match = \regexp{(\A|\,\s)\[(.+?)\]}, replace = {$1}]
    }
  }
}

第一个映射是从 MWE 中详细提取的，因此是 Andrew Swann 的答案。第二个映射将紧跟在单词字符（即字母）后面的括号对转换为缩写点。最后，如果用括号括起来，第三部分将删除整个名字（[John] Lennon并且Lennon, [John]两者都匹配并转换为Lennon）。
