幫助：尋找通用（且優雅）的陣列（變數）映射語法來保存內容

Question

如果其他地方已經討論過這個問題，我很抱歉，但如果是的話，我找不到它。

我是我大學學術論文範本的作者，但我絕對不是 TeX 專家。在此範本中，我廣泛使用了使用臨時（自）定義的陣列映射的設定檔。例如：

\arraymay{cover}
\cover{phd}={phd_cover_file.pdf}
\cover{msg}={msc_cover_file.pdf}
\arraymap{margin}
\margin{cover,left}={5cm}
\margin{cover,right}={5cm}
\margin{cover,top}={4cm}
\margin{cover,bottom}={4cm}
\margin{main,left}={3cm}
\margin{main,right}={3cm}
\margin{main,top}={2cm}
\margin{main,bottom}={2cm}

鍵中的逗號是為了視覺效果而使用的，被視為普通字符，即“ \margin{cover,bottom}={2cm}”中的鍵是“ cover,bottom”。

我稍後可以訪問這些值，如下所示：

\def\manuscripttype{phd}
The cover file is ``\thecover[\manuscripttype]'' and the margins for the cover are ``\themargin[cover,left], \themargin[cover,right], \themargin[cover,top], and \themargin[cover,bottom].''

將產生

The cover file is “phd_cover_file.pdf” and the margins for the cover are “3cm, 3cm, 2cm, and 2cm.”

是否有其他（實體）套件實現此功能？如果沒有，是否有一些可靠的方法來實現它（可能基於 KV 套件之一）？謝謝。

你可以這樣做pgfkeys：

\documentclass{article}
\usepackage[T1]{fontenc}

\usepackage{pgfkeys}

\pgfkeys{
  lourenco/.cd,
  cover/phd/.initial={},
  cover/msc/.initial={},
  margin/cover/left/.initial=0pt,
  margin/cover/right/.initial=0pt,
  margin/cover/top/.initial=0pt,
  margin/cover/bottom/.initial=0pt,
  margin/main/left/.initial=0pt,
  margin/main/right/.initial=0pt,
  margin/main/top/.initial=0pt,
  margin/main/bottom/.initial=0pt,
}

\newcommand{\setlourenco}[1]{\pgfkeys{lourenco/.cd,#1}}
\newcommand{\thecover}[1]{%
  \pgfkeysvalueof{/lourenco/cover/#1}%
}
\newcommand{\themargin}[1]{%
  \pgfkeysvalueof{/lourenco/margin/#1}%
}

%% settings
\setlourenco{
  cover/phd=phd-cover-file.pdf,
  cover/msc=msc-cover-file.pdf,
  margin/cover/left=5cm,
  margin/cover/right=5cm,
  margin/cover/top=4cm,
  margin/cover/bottom=4cm,
  margin/main/left=3cm,
  margin/main/right=3cm,
  margin/main/top=2cm,
  margin/main/bottom=2cm,
}

\def\manuscripttype{phd}

\begin{document}

The cover file is ``\thecover{\manuscripttype}'' and the margins 
for the cover are ``\themargin{cover/left}, \themargin{cover/right},
\themargin{cover/top}, and \themargin{cover/bottom}.''

\end{document}
