gitinfo（xstring）：由于版本号前面有“tag：”，标签信息不起作用

Question

我们需要一个替代的 git-set-info 例程：

\documentclass{article}

\usepackage{gitinfo}

\usepackage{filecontents}

\begin{filecontents}{gitHeadInfo.gin}
\usepackage[%
        refnames={ (HEAD, tag: 1.0, master)}
     ]{mygitsetinfo}% call the new routine here
\end{filecontents}

\begin{document}

\gitVtags
\gitVtag
\gitVtagn

\end{document}

\IfDecimal如果有小数，则该例程需要输入小数。如果我们有tag: 1.0而不是1.0，我们需要删除第一个。用于提供的功能tag:还提供可以执行此操作的命令。允许您在某个字符处剪切字符串并将两部分保存在两个宏中。我使用了和来保存这些字符串，尽管我们实际上只对右侧部分感兴趣。xstringgitinfo\IfDecimal\StrCut\lcut\rcut

为了同时允许tag: 1.0和1.0，我使用了嵌套条件。首先，我剪切字符串并保存两个部分。然后我测试是否\rcut为小数。如果是，则使用该结果。如果不是，看看未剪切的参数本身是否为小数。如果是，则使用它。如果不是，则不返回任何内容。

将以下内容保存为mygetsetinfo.sty：

\git@vtag{\gitInf@refnames}

结果看起来并不十分令人印象深刻，但我相信它比‘（无）’有所改进......

结果看起来并不令人印象深刻...

这也适用于原文所涵盖的情况gitsetinfo：

\documentclass{article}

\usepackage{gitinfo}

\usepackage{filecontents}

\begin{filecontents}{gitHeadInfo.gin}
\usepackage[%
        refnames={ (HEAD, 1.0, master)}
     ]{mygitsetinfo}% call the new routine here
\end{filecontents}

\begin{document}

\gitVtags
\gitVtag
\gitVtagn

\end{document}

看起来相同的结果...
