Biblatex - idemtracker 未按预期工作

Question

idemtracker当连续引用同一作者的几部作品时，效果并不如预期。这
是我得到的结果：

我原本期望得到：

MIT. "Bla bla 2020"
Idem, "Bla bla 2018"
Idem, "Bla bla 2019"
Idem, "Bla bla 2018"

在参考书目中不存在这样的问题，Biblatex 正确地检测到三次是同一位作者。

有没有办法改变 Biblatex 的行为以实现所需的结果？

\documentclass{book}
\usepackage[backend=biber, style=verbose-trad1, idemtracker=true]{biblatex}

\begin{filecontents}{bibliography.bib}
@Online{MIT2020,
  author = {MIT},
  url = {blablabla.com},
  title = {Bla bla 2020},
}
@Online{MIT2019,
  author = {MIT},
  url = {blablabla.com},
  title = {Bla bla 2019},
}
@Online{MIT2018,
  author = {MIT},
  url = {blablabla.com},
  title = {Bla bla 2018},
}
\end{filecontents}

\addbibresource{bibliography.bib}

\begin{document}
\footcite{MIT2020}
\footcite{MIT2018}
\footcite{MIT2019}
\footcite{MIT2018}

\printbibliography
\end{document}

Answer 1

正如 Ulrike 在评论中所说，verbose-trad1打印第一个引用的完整引用，而这些引用没有提供使用选项同上。

这是启用的方法同上\ifciteidem也适用于首次引用。我们的想法是向 bibmacros 中添加对author、editor和 的测试translator。

\documentclass{article}
\usepackage[backend=biber, style=verbose-trad1, idemtracker=true]{biblatex}

\makeatletter
\renewbibmacro*{author}{%
  \ifboolexpr{
    test \ifuseauthor
    and
    not test {\ifnameundef{author}}
  }
    {\usebibmacro{bbx:dashcheck}
       {\bibnamedash}
       {\ifboolexpr{test {\ifcitation} and test {\ifciteidem}}
          {\bibstring[\mkibid]{idem\thefield{gender}}}
          {\printnames{author}}%
        \setunit{\printdelim{authortypedelim}}%
        \usebibmacro{bbx:savehash}}%
     \usebibmacro{authorstrg}}
    {\global\undef\bbx@lasthash}}

\renewbibmacro*{bbx:editor}[1]{%
  \ifboolexpr{
    test \ifuseeditor
    and
    not test {\ifnameundef{editor}}
  }
    {\usebibmacro{bbx:dashcheck}
       {\bibnamedash}
       {\ifboolexpr{test {\ifcitation} and test {\ifciteidem}}
          {\bibstring[\mkibid]{idem\thefield{gender}}}
          {\printnames{editor}}%
        \setunit{\printdelim{editortypedelim}}%
        \usebibmacro{bbx:savehash}}%
     \usebibmacro{#1}%
     \clearname{editor}}
    {\global\undef\bbx@lasthash}}

\renewbibmacro*{bbx:translator}[1]{%
  \ifboolexpr{
    test \ifusetranslator
    and
    not test {\ifnameundef{translator}}
  }
    {\usebibmacro{bbx:dashcheck}
       {\bibnamedash}
       {\ifboolexpr{test {\ifcitation} and test {\ifciteidem}}
          {\bibstring[\mkibid]{idem\thefield{gender}}}
          {\printnames{translator}}%
        \setunit{\printdelim{translatortypedelim}}%
        \usebibmacro{bbx:savehash}}%
     \usebibmacro{#1}%
     \clearname{translator}}
    {\global\undef\bbx@lasthash}}

以下方法稍微更模块化

\documentclass{article}
\usepackage[backend=biber, style=verbose-trad1, idemtracker=true]{biblatex}

\makeatletter
\newbibmacro{ifrepeatauthor}{\ifciteidem}
\newbibmacro{repeatedauthor}{%
  \bibstring[\mkibid]{idem\thefield{gender}}}

\AtBeginBibliography{%
  \renewbibmacro{ifrepeatauthor}{\usebibmacro{bbx:dashcheck}}%
  \renewbibmacro{repeatedauthor}{\bibnamedash}%
}

\renewbibmacro*{author}{%
  \ifboolexpr{
    test \ifuseauthor
    and
    not test {\ifnameundef{author}}
  }
    {\usebibmacro{ifrepeatauthor}
       {\usebibmacro{repeatedauthor}}
       {\printnames{author}%
        \setunit{\printdelim{authortypedelim}}%
        \usebibmacro{bbx:savehash}}%
     \usebibmacro{authorstrg}}
    {\global\undef\bbx@lasthash}}

\renewbibmacro*{bbx:editor}[1]{%
  \ifboolexpr{
    test \ifuseeditor
    and
    not test {\ifnameundef{editor}}
  }
    {\usebibmacro{ifrepeatauthor}
       {\usebibmacro{repeatedauthor}}
       {\printnames{editor}%
        \setunit{\printdelim{editortypedelim}}%
        \usebibmacro{bbx:savehash}}%
     \usebibmacro{#1}%
     \clearname{editor}}
    {\global\undef\bbx@lasthash}}

\renewbibmacro*{bbx:translator}[1]{%
  \ifboolexpr{
    test \ifusetranslator
    and
    not test {\ifnameundef{translator}}
  }
    {\usebibmacro{ifrepeatauthor}
       {\usebibmacro{repeatedauthor}}
       {\printnames{translator}%
        \setunit{\printdelim{translatortypedelim}}%
        \usebibmacro{bbx:savehash}}%
     \usebibmacro{#1}%
     \clearname{translator}}
    {\global\undef\bbx@lasthash}}
