Biblatex 字段值和比较

我想改变 biblatex 中基于哈希字段打印作者姓名的行为。这篇文章应该能说明我难以理解的内容。

梅威瑟：

\documentclass{article}
\usepackage[backend=biber, style=phys, punctfont=true]{biblatex}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{doe_design_2013,
  author = {Doe, John B.},
  journaltitle = {Acme Society Journal},
  date = {2013-03-08},
  title = {Design of alpha widgets},
  volume = {1},
  issue = {1},
  pages = {10}
}
@article{doe_alpha_2014,
  author = {Smith, Jane J. and Doe, John B.},
  journaltitle = {Acme Society Journal},
  date = {2014-03-08},
  title = {Alpha widgets in space},
  volume = {2},
  issue = {1},
  pages = {5}
}
\end{filecontents}
\addbibresource{\jobname.bib}
\newcommand*{\mystr}{7ba24cb78eaec483f680a08422f4d516}
\newcommand*{\myhash}{7ba24cb78eaec483f680a08422f4d516}
\renewcommand*{\mkbibnamefirst}[1]{
  \iffieldequals{hash}{\myhash}{\mkbibbold{#1}}{#1}
}
\renewcommand*{\mkbibnamelast}[1]{
  \iffieldequalstr{hash}{7ba24cb78eaec483f680a08422f4d516}
  {\savefield{hash}{\myhash}\mkbibbold{#1}}
  {#1}
}
\begin{document}

Commands equal: \ifdefequal{\myhash}{\mystr}{True}{False}

Replacement text equal: \ifdefstrequal{\myhash}{\mystr}{True}{False}

\nocite{*}
\printbibliography[title={Test}]

Commands equal: \ifdefequal{\myhash}{\mystr}{True}{False}

Replacement text equal: \ifdefstrequal{\myhash}{\mystr}{True}{False}

\pagenumbering{gobble}

\end{document}

我理解 \myhash 的初始值与 biblatex 哈希字段不同，即使它们的字符串值与初始JB不是粗体，而下一个出现的是粗体。

我想了解的是：

  1. 如何将 biblatex 字段的字符串值与命令的字符串值进行比较？
  2. biblatex 哈希字段的值是什么
  3. 我如何确定命令或 biblatex 字段的实际值？

我觉得我缺少一个核心概念，以及在 LaTeX 中调试问题的更好方法。

（我知道这个问题，但我的问题更多是关于 LaTeX/biblatex 编程）

答案1

\detokenize在将字符串分配给宏之前，您需要先获取该字符串。最简单的方法是通过以下方式完成\edef：

\edef\myhash{\detokenize{7ba24cb78eaec483f680a08422f4d516}}

现在\iffieldsequals有成功的机会。将此与https://tex.stackexchange.com/a/6833/15925
