书目标签采用字母样式，但包含完整的 4 位年份

Question

考虑以下使用的书目示例字母的风格，maxalphanames = 1并停用+如果有多个作者：

如何才能在标签中实现完整的4位数字年份？ 因此在这种情况下所需的输出将是：Baa1989

我发现了一个来源解释如何定义完整的自定义标签。但我很难相信没有更简单、更通用的 switch 来切换。在手册中找不到任何内容。

我正在寻找解决方案biblatex + biber。

谢谢。

据我所知，你将不得不诉诸\DeclareLabelalphaTemplate，但这并不是太糟糕。

我们可以直接复制默认值biblatex.def并更改\field[strwidth=2,strside=right]{year}为\field{year}

\DeclareLabelalphaTemplate{
  \labelelement{
    \field[final]{shorthand}
    \field{label}
    \field[strwidth=3,strside=left,ifnames=1,pcompound=true]{labelname}
    \field[strwidth=1,strside=left,pcompound=true]{labelname}
  }
  \labelelement{
    \field{year}    
  }
}

就是这样。
