修改eprint命令使得amsrefs正确超链接arxiv文章

一个基本的使用amsrefs生成MathScinet数学参考文献的例子是

\begin{filecontents}{\jobname.bib}
@ARTICLE{2015arXiv151004332G,
   author = {{Guo}, B. and {Huang}, Z. and {Phong}, D.~H.},
    title = "{Pseudo-locality for a coupled Ricci flow}",
  journal = {ArXiv e-prints},
archivePrefix = "arXiv",
   eprint = {1510.04332},
 primaryClass = "math.DG",
 keywords = {Mathematics - Differential Geometry},
     year = 2015,
    month = oct,
   adsurl = {http://adsabs.harvard.edu/abs/2015arXiv151004332G},
  adsnote = {Provided by the SAO/NASA Astrophysics Data System}
}
\end{filecontents}

 

这时产生的超链接是不对的, 我们只需在导言区加入
\renewcommand{\eprint}[1]{arXiv:math/#1}即可自动链接到pdf, 或者
\renewcommand{\eprint}[1]{arXiv:math/#1}自动链接到摘要.

上面的修改并不能自动根据PrimaryClass更改链接的形式, 如果要完全修复, 则需要修改如下两个文件:

文件下载:
1.  amsrefs.dtx/amsrefs.ins/amsxport.dtx/amsxport.ins
2. 下载后运行latex amsrefs.ins amsxport.ins 则可生成最新的amsrefs.sty以及五个参考文献样式文件.

此时再次运行最开始的tex代码(不需要重新定义eprint命令了), 最终效果图如下:
