如何在动态调用的宏名称中动态更改 pgfkeys 选项的大小写？

我希望我描述得正确。在一个较大的项目中，我试图使我的文档级命令采用 CamelCase 格式，但当使用旨在动态调用命令的键和值时，这很困难，因为它们都是小写。我确信这是一个可扩展性问题，但我只是没有看到解决方案。我搜索了该网站，但找不到一个我认为显然相关的示例。

在 MWE 中，命令\AlwaysDogHere、\AlwaysCatHere和\AlwaysBotHere 通常位于序言中，但我已将它们移到文档中，以便可以轻松看到它们的结果。输出typeout{}是正确的，但相关命令没有被正确地动态构建，这是我的问题。请参阅 MWE 中的注释。只要文档命令像键和值一样都是小写，一切都会正常工作。

我的尝试：

% !TEX program = lualatexmk
% !TEX encoding = UTF-8 Unicode

\documentclass{article}
\usepackage{pgfkeys}
\pgfkeys{%
  /mwe/optiond/.cd,
  initial@setup/.style={%
    /mwe/options/mwe@example/.initial=dog,
  },%
  initial@setup,%
  mykey/.is choice,
  mykey/.default=cat,
  mykey/dog/.style={/mwe/options/mwe@example=dog},
  mykey/cat/.style={/mwe/options/mwe@example=cat},
  mykey/bot/.style={/mwe/options/mwe@example=bot},
}%
\NewDocumentCommand{\AlwaysDogHere}{}{%
  % This command does something related to dog.
  %\relax
  Dog
}%
\NewDocumentCommand{\AlwaysCatHere}{}{%
  % This command does something related to cat.
  %\relax
  Cat
}%
\NewDocumentCommand{\AlwaysBotHere}{}{%
  % This command does something related to bot.
  %\relax
  Bot
}%
% The key should be lowercase in the \typeout{} output.
\typeout{}%
\typeout{Working with \pgfkeysvalueof{/mwe/options/mwe@example}}%
\typeout{}%

\begin{document}
Hello.
% I need the key's first letter to be capitalized in the 
% next line so the correct macro will be invoked dynamically
% in situ.
\csname Always\MakeUppercase\expandafter\expandafter\pgfkeysvalueof{/mwe/options/mwe@example}  Here\endcsname%

\end{document}

你正在\Alwaysdog Here用d和 空格进行调用，你可以使用 进行完全扩展\expanded（注意\MakeUppercase这里需要 2022 LateX）


\documentclass{article}
\usepackage{pgfkeys}
\pgfkeys{%
  /mwe/optiond/.cd,
  initial@setup/.style={%
    /mwe/options/mwe@example/.initial=dog,
  },%
  initial@setup,%
  mykey/.is choice,
  mykey/.default=cat,
  mykey/dog/.style={/mwe/options/mwe@example=dog},
  mykey/cat/.style={/mwe/options/mwe@example=cat},
  mykey/bot/.style={/mwe/options/mwe@example=bot},
}%
\NewDocumentCommand{\AlwaysDogHere}{}{%
  % This command does something related to dog.
  %\relax
  Dog
}%
\NewDocumentCommand{\AlwaysCatHere}{}{%
  % This command does something related to cat.
  %\relax
  Cat
}%
\NewDocumentCommand{\AlwaysBotHere}{}{%
  % This command does something related to bot.
  %\relax
  Bot
}%
% The key should be lowercase in the \typeout{} output.
\typeout{}%
\typeout{Working with \pgfkeysvalueof{/mwe/options/mwe@example}}%
\typeout{}%

\begin{document}
Hello.
% I need the key's first letter to be capitalized in the 
% next line so the correct macro will be invoked dynamically
% in situ.

\expandafter\show\csname Always\MakeUppercase\expandafter\expandafter\pgfkeysvalueof{/mwe/options/mwe@example}  Here\endcsname


\expandafter\show\csname Always\expanded{\noexpand\MakeUppercase\pgfkeysvalueof{/mwe/options/mwe@example}}Here\endcsname

\csname Always\expanded{\noexpand\MakeUppercase\pgfkeysvalueof{/mwe/options/mwe@example}}Here\endcsname

\end{document}
