使用 BibLaTeX 表示数字的复数形式（期刊期刊）

Question

术语“number”没有复数形式，它指的是期刊的期号。我尝试定义一个复数形式（n ^os），但不足以打印它（例如双期文章）。我该怎么办？我的风格是 verbose-trad2。

梅威瑟：

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[french]{babel}
\usepackage[T1]{fontenc}

\usepackage[style=verbose-trad2,language=french,backend=biber]{biblatex}

\addbibresource{numero.bib}

\DeclareFieldFormat[article]{number}{\bibstring{number}\addnbspace #1}

\NewBibliographyString{numbers}

\DefineBibliographyStrings{french}{%
  numbers = {{num\'eros}{n\textsuperscript{os}}}
}

\begin{document}
citation\footcite{doe_life_2011}
\end{document}

数字.bib：

@article{doe_life_2011,
  title = {My Life},
  number = {137-138},
  journal = {{IJAS}},
  author = {Dan, {John}},
  pages = {139--153},
   date = {2011}
}

仅打印numberbibstring 不会考虑新numbers字符串。您必须检查字段是单个数字还是数字范围，然后相应地打印它。以一种非常简单的方式，您可以使用：

\DeclareFieldFormat[article]{number}{%
  \iffieldnum{number}{\bibstring{number}\addnbspace}%
    {\iffieldnums{number}{\bibstring{numbers}\addnbspace}%
    {}}%
  #1}

它检查数字字段是否为单个数字，number如果是，则使用 bibstring，否则使用新创建的numbers。非数字字段将被打印没有任何 bibstring。如果您想将 bibstring 添加number到此类字段，您可以将其添加到复数形式检查中：

\DeclareFieldFormat[article]{number}{%
  \iffieldnum{number}{\bibstring{number}\addnbspace}%
    {\iffieldnums{number}{\bibstring{numbers}\addnbspace}%
    {\bibstring{number}\addnbspace}}%
  #1}

因此，只要有数字字段，number就会使用 bibstring，并使用numbers复数形式的 bibstring。
