同一命令被使用多次，但我只得到最後一個輸出

Question 1

通常你不將元標題「編輯者：」加入到收集元資訊的巨集中，例如

\newcommand{\editor}[1]{\def\@editor{\raggedright \textbf{Edited by:}\newline #1}}

請注意，我使用 LaTeX 命令\newcommand作為頂級元宏（這是更好的！），並且\gdef內部元存儲的定義不需要該命令，即\@editor；\def就足夠了。

在您的情況下，您可以使用元命令來增加內部儲存：

\newcommand{\editor}[1]{\edef\@editor{\@editor #1}}

為了對現有設定進行最少的更改，最終版本如下所示

\newcommand{\editor}[1]{\protected@edef\@editor{\@editor\newline#1\vspace{3pt}}}

完整代碼在最後給出。您會發現一些變化是不可避免的。這次我還清理了整體程式碼。

Question 2

\editor正如一些評論中所說，和的當前定義\reviewer旨在設定內容，並且每個定義都會覆蓋前一個定義。

這是一個簡單的定義（使用etoolbox套件的清單處理工具，即使用\RequirePackage{etoolbox}或`\usepackage{etoolbox}來載入它）。

\newcommand{\@editor}{}
\newcommand{\@reviewer}{}

\newcommand{\editor}[1]{\listadd{\@editor}{#1}}
\newcommand{\reviewer}[1]{\listadd{\@reviewer}{#1}}
\newcommand{\printeditor}{Edited By:\newline\dolistloop{\@editor}}
\newcommand{\printreviewer}{Reviewed By:\newline\dolistloop{\@reviewer}}

透過這種方式，命令\editor{some text}並將\reviewer{some text}其參數新增至編輯器清單（儲存在\@editor和中\@reviewer）。這兩個命令\printeditor 循環\printreviewer遍歷列表並列印各自列表的內容。

例如，在的給定定義中將\@editor和替換\@reviewer為\printeditor和。\printreviewer\maketitle
