类似 REVTex 的从属关系和作者命令

Question

我正在尝试实现我自己的\affiliation和版本，以便在海报中使用。我希望有选项以、和\author的形式显示隶属关系索引。阿拉伯语和 alphaph 输出都可以正常工作，但 不行。\arabic\alph\fnsymbol\fnsymbol

梅威瑟：

\documentclass[]{article}
\usepackage{etoolbox}
\begin{document}
\newcounter{x}
\csxdef{tmp}{}
\stepcounter{x}
\csxdef{tmp}{\csuse{tmp}\alph{x},}
\stepcounter{x}
\csxdef{tmp}{\csuse{tmp}\alph{x}}
Authorname$^{\csuse{tmp}}$ %
\setcounter{x}{0}
\csxdef{tmp}{}
\stepcounter{x}
\csxdef{tmp}{\csuse{tmp}\arabic{x},}
\stepcounter{x}
\csxdef{tmp}{\csuse{tmp}\arabic{x}}
Authorname$^{\csuse{tmp}}$ %
\setcounter{x}{0}
\csxdef{tmp}{}
\stepcounter{x}
\csxdef{tmp}{\csuse{tmp}\fnsymbol{x},}
\stepcounter{x}
\csxdef{tmp}{\csuse{tmp}\fnsymbol{x}}
Authorname$^{\csuse{tmp}}$ %
\setcounter{x}{0}
\csxdef{tmp}{}
\stepcounter{x}
\csxdef{tmp}{\csuse{tmp}\alph{x},}
\stepcounter{x}
\csxdef{tmp}{\csuse{tmp}\alph{x}}
Authorname$^{\csuse{tmp}}$ %
\end{document}

输出：

以及错误信息：

 Missing } inserted. ...csuse{tmp} $\to$ Authorname$^{\csuse{tmp}

我理解，这\fnsymbol会产生数学模式输出，而我的代码缺少文本和数学模式之间的正确切换，但我找不到发生这种情况的地方。

感谢大家，我凌乱的最终代码已经准备好了。这是我第一次编写软件包和使用 etoolbox。
