如何实现引用连续的数字 使用短线连接 即：[1,2] 变成 [1-2]
发布于 2021-06-16 16:11:23
我们有些时候希望这样的效果，下面是hack实现的代码，大家可以拿去用了：
\begin{filecontents}{\jobname.bib}
@article{demo1,
title = {Some things {I} did},
author = {Other, A. N.},
journal = {J. Irrep. Res.},
year = {2012},
pages = {x-y}
}
@article{demo2,
title = {Cool!},
author = {Nobacon, D.},
journal = {Ann. Improb. Res.},
year = {2012},
pages = {a-b}
}
\end{filecontents}
\documentclass{article}
\usepackage[numbers,sort&compress]{natbib}
\usepackage{etoolbox}
\makeatletter
\patchcmd{\NAT@citexnum}
{%
\ifx\NAT@last@yr\relax
\def@NAT@last@yr{\@citea}%
\else
\def@NAT@last@yr{--\NAT@penalty}%
\fi
}
{%
\def@NAT@last@yr{--\NAT@penalty}%
}
{}{\FAIL}
\makeatother
\bibliographystyle{unsrtnat}
\begin{document}
\cite{demo1,demo2}
\bibliography{\jobname}
\end{document}
