我有一堆同一位作者的 bib 条目，它们都标有完整日期。问题是其中一些条目的日期相同，因此需要一个 extrayear 标签。但 extrayear 按年份工作，而不是按完整日期工作。所以看起来我只能标记所有条目或不标记任何条目。有人知道在下面的例子中，两个中间条目如何获得标签“a”和“b”，而其他条目没有标签吗？

答案1

随着新的\DeclareExtradate（见https://github.com/plk/biblatex/issues/540biblatex) 在3.8/Biber 2.8中引入，你只需要

\DeclareExtradate{%
  \scope{
    \field{labelyear}
    \field{year}
  }
  \scope{
    \field{labelmonth}
  }
  \scope{
    \field{labelday}
  }
}

由于您使用的日期格式已将extradate字段（以前称为extrayear）放入正确的位置，我们甚至不需要更改日期宏。如果需要不同的输出，可能需要修改日期打印宏2017-02-27b。

答案2

我尝试创建一个独立的 Lua 模块来修复该bbl文件。排序在这里不是问题，它使用通用year-month-day格式。在此示例中，我们尝试获取从a,b,c,d到 的一系列,a,b,。我们需要提前搜索，否则我们将获得一系列a,a,b,a。我决定更改系列的排序键是namehash+ year+ month+ day，它是来自文件的字段的组合bbl。该算法可以简要描述如下：

  • 如果两个连续日期不相等，请注释掉第一行。
  • 如果是，请使用计数器并修改两行中该字段的数字（这是第二个 TeX 参数），例如修改为 1 和 2、2 和 3...
  • 如果没有年、月、日数据，则故意跳过某个条目。

编辑：year由于使用了排序键，我们得到了、year+month和year++的单独系列。我已通过添加默认值修复了修复程序，因此如果没有或数据，month它就可以正常工作。daymonthday

在我们的示例中，我们将在前四次出现时获得更改extrayear（这是以前的版本，请参阅修订列表）：

\字段{额外年份}{1}
\字段{额外年份}{2}
\字段{额外年份}{3}
\字段{额外年份}{4}

到

%\field{额外年份}{1}
\field{额外年份}{1}%2
\field{额外年份}{2}%3
%\field{额外年份}{4}

编辑：extrayear出于安全原因，在新版本中添加了新字段而不是进行更改，例如\field{userb}{1}。

我们可以比较使用修复程序之前和之后的结果：

mwe，比较

笔记：我认为文本中的引用应该以某种方式进行修复（希望在级别上biblatex），它看起来不对，因为我们可以发现AuthorA 2014两次，但针对两本不同的书。如果我们使用\nocite{*}，那就没问题了。Ulrike Fischer 建议重新定义\cite命令。

我正在以这种方式使用所谓的修复程序（Lua 独立库）：

lualatex mal-biber
biber mal-biber
luatex --luaonly mal-fixer.lua mal-biber
lualatex mal-biber

如果一切正常，您可能会在终端中发现两行：

Mal-fixer 正在处理 mal-biber.bbl 文件...
Mal-fixer 已完成 12 项任务！

虽然我运行的是lualatex，但任何 LaTeX 格式都可以使用。我附上了主要的 TeX 代码和 Lua 库。

%! *latex mal-biber.tex

我希望有人能给出更好的答案，但同时我只想指出，你可以在年份字段中放入更多内容，而 biber 不会抱怨：

@article{authorA1,
 author={authorA},
 title={blaa},
 year={03.03.2014}
 }

@article{authorA2,
 author={authorA},
 title={blab},
 year={04.03.2014}
 }


@article{authorA3,
 author={authorA},
 title={blac},
 year={04.03.2014}
 }

@article{authorA4,
 author={authorA},
 title={blad},
 year={05.03.2014}
 }
