无需 Bibtex 即可按出现顺序引用多个参考文献

Question

这个问题与我之前问的一个问题相关这里。我想按出现的顺序引用参考文献，而不用 Bibtex 和回答确实如此。但是，请考虑一下我有以下参考书目：

\begin{thebibliography}{C}
\bibitem{ref1}{AAAA}
\bibitem{ref2}{BBBB}
\bibitem{ref3}{CCCC}
\bibitem{ref4}{DDDD}
\bibitem{ref5}{EEEE}
\end{thebibliography}

代码\cite{ref2} and \cite{ref3, ref4, ref5}将给出[1] and [2,3,4]我想要的[1] and [2-4]。我如何改变前面答案中给出的代码？请注意，使用\usepackage{cite}将输出[1] and [4-6]不按出现顺序排列的内容。

Answer 1

实施不使用 Bibtex 按出现顺序对参考书目进行排序天真地假设 的参数\citation始终只有一个键。这对于 的标准实现是一个有效的假设，但对于的\cite实现则不是。cite\cite

以下简单扩展也应处理逗号分隔列表。唯一的区别是引入了 CSV 循环\citation，并将宏的核心移至\citation@i。
