在 biblatex 中选择简写

Question

我有一个大型.bib数据库，其中许多条目都shorthands定义了字段。

当我想将这些简写的使用限制在引用最多的文本时，我通常会将参考书目数据库的副本创建到工作目录，然后删除不需要的简写或将字段更改为类似的内容XXXshorthand，以便将其从 bibtex/biber 中隐藏起来。

现在我想使该过程自动化。我设想了两种实现该目标的方法：

1. 我可以在序言中设置类似\includeonly命令的东西，添加允许使用简写的条目（我不知道是否可能或如何做到这一点，但它会检查 bib 条目是否等于列出的条目，如果不相等，则向 \clearfield{shorthand}它们添加）。

2. 一种非常不同的方法，但可能比此更通用，即检查给定的条目是否被引用超过三次或五次（可由用户定义），如果是，则允许它使用其简写。

所以问题是这是否可能，如果可能，如何可能？

按照@ienissei的评论，它指出@lockstep 的回答，到目前为止，我已经能够忽略shorthandintro（打印字符串citedas— 英文为“从今以后引用为......” — 和第一个引用中的简写）并使后续引用（最多三个）忽略简写并使用 bibmacro cite:short。

这是我迄今为止所做工作的 MWE，绘制在所提及的答案提供的 MWE 的顶部：

它运行得很好，除了它仍然打印简写列表中的条目。

编辑2：我修改了代码，因为它无法处理没有简写的条目。问题出在\iffieldundef{shorthand}。

Answer 1

定义一个合适的书目类别并在 中使用它\printshorthands。这与我的回答非常相似如何将参考书目分为“引用的作品”和“未引用的作品”？。

\documentclass{article}

\usepackage[style=verbose-trad3,citecounter=true]{biblatex}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
  @misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
  shorthand = {AL},
}
@misc{B02,
  author = {Buthor, B.},
  year = {2002},
  title = {Bravo},
  shorthand = {BR},
}
\end{filecontents}

\addbibresource{\jobname.bib}

% Command to tell how much citations activate the use of shorthands
\newcommand{\shthreshold}[1]{\newcommand{\SHthreshold}{#1}}
\shthreshold{3}

\renewbibmacro*{cite}{%
  \usebibmacro{cite:citepages}%
  \global\togglefalse{cbx:loccit}%
  \ifciteseen
    {\ifciteibid
       {\ifloccit
    {\usebibmacro{cite:ibid}}
    {\iffieldundef{shorthand}
       {\usebibmacro{cite:opcit}}
        {\ifnumgreater{\value{citecounter}}{\SHthreshold}%
        {\usebibmacro{cite:shorthand}}
        {\usebibmacro{cite:short}}}}}
       {\iffieldundef{shorthand}
    {\usebibmacro{cite:short}}
    {\usebibmacro{cite:shorthand}}}}
    {\usebibmacro{cite:full}}}

\renewbibmacro*{cite:full}{%
  \usebibmacro{cite:full:citepages}%
  \printtext[bibhypertarget]{%
    \usedriver
      {\DeclareNameAlias{sortname}{default}}
      {\thefield{entrytype}}}%
  \ifnumgreater{\value{citecounter}}{\SHthreshold}{
    \usebibmacro{shorthandintro}}{}}

\DeclareBibliographyCategory{allowshorthand}
\AtEveryCitekey{%
  \ifnumgreater{\value{citecounter}}{\SHthreshold}{%
    \addtocategory{allowshorthand}{\thefield{entrykey}}%
  }{%
  }%
}

\textheight=250pt% just for the example

\begin{document}

\printshorthands[category=allowshorthand]
