在 biblatex 中格式化页码

Question

考虑以下biblatex/biber最小示例：

\documentclass{article}

\usepackage{filecontents}
\begin{filecontents*}{references.bib}
@article{abc,
  author  = {A Author},
  title   = {The title},
  journal = {Journal of Journals},
  volume  = {12},
  number  = {34},
  year    = {1234},
  pages   = {12345-23456}
}
\end{filecontents*}

\usepackage{biblatex,siunitx}

\addbibresource{references.bib}

\begin{document}

\nocite{*}

\printbibliography

Current page number format: 12345--23456

Ideal page number format: \num{12345}--\num{23456}

\end{document}

我想使用以下方式格式化页码siunitx命令\num，产生如下范围：

我怎样才能做到这一点？

Answer 1

我们可以修改命令\mknormrange以将所有页码包装在siunitx命令中\num。然后我们只需确保\mknormrange也应用于pages字段格式（它通常不应用于该字段，因为 Biber 已经进行了足够的预处理）。

biblatex对于页码的定义相当宽松，允许除整数之外的字符串作为页码传递（例如122a，iv），但此解决方案仅适用\num于通过更严格测试的字符串\ifinteger。此处修改的宏的原始定义可以在中找到biblatex.sty。本质上，我们只是\ifinteger在每次调用时添加测试\blx@range@out@value，并在其为真时将页码包装在其中\num。例如，的原始定义\blx@normrange@process是

\def\blx@normrange@process#1#2{%
  \blx@range@out@value{#1\bibrangedash#2}}

我们把它读成

\def\blx@normrange@process#1#2{%
  \ifinteger{#1}
    {\ifinteger{#2}}
    {\@secondoftwo}
  {\blx@range@out@value{\num{#1}\bibrangedash\num{#2}}}
  {\blx@range@out@value{#1\bibrangedash#2}}}

总共

\documentclass{article}

\usepackage{biblatex,siunitx}
