如何在参考书目中以正确的顺序使用年份后的预定义小写字母（例如 1990f [1969]）

Question

我以前从未见过使用正式extradate字母的引用（我只见过extradate根据特定参考书目中引用的作品计算消歧字母的文献），但这里有一种方法可以实现这一点。

首先，你需要让你的输入更易于机器阅读。我决定拆分

  year      = {1990f [1969]},
  edition   = {1999},

进入组件

  year              = {1990},
  officialextradate = {6},
  origyear          = {1969},
  editiondate       = {1999},
  options           = {officialextradate,labeldateparts=false},

其中officialextradate和editiondate是我们需要用.dbx数据模型声明的新字段。

officialextradate,labeldateparts=false所有引用“官方”信件的条目都需要这两个选项extradate。这些选项告诉 Biber 忽略这些条目进行extradate计算，并告诉我们的代码改用officialextradate。

如果officialextradate设置了选项，我们只需注入officialextradate。extradate由于我们必须完全禁用labelyear计算，我们通过定义labeldatesource并稍微弄乱一些内部结构来恢复它，以恢复行为，就像我们没有设置一样labeldateparts=false。如果可用，我们还会按信息排序officialextradate。然后只需确保在适当的情况下打印origdate和。其他一切都可以通过已经存在的设施来处理。editiondatebiblatex
