设置覆盖 pgfkeys 选项

Question

我有一个自定义宏\MyMacro，用于pgfkeys指定三件事：

1. 要text=输出的
2. color=文本的
3. 放置punctuation=在最后。

我想定义宏\SetUpMyMacroAdjustedOptions来指定覆盖选项下一个调用\MyMacro。

例如，

\SetUpMyMacroAdjustedOptions{color=magenta, punctuation={.}}

我想

\MyText{text={xxx}, color=brown, puncutation={:}}

被视为

\MyText{text={xxx}, color=magenta, punctuation={.}}}

也就是说，选项color=magenta和punctuation={!}来自\SetUpMyMacroAdjustedOptions会覆盖任何指定的选项，并覆盖这些选项的任何默认设置。

以下是我的尝试几乎可以正常工作，因为覆盖puncutaion=已应用，但color=实际上没有。此外，在后续调用之间似乎不会重置选项\MyMacro。

\MyMacro调用

\pgfkeys{/MyMacro/.cd, default MyMacro options,#1,adjust MyMacro options}%

其中#1是用户指定的选项，并adjust MyMacro options通过调用 进行设置\SetUpMyMacroAdjustedOptions。我在这里的假设是 键的最后一个设置将覆盖任何先前的设置，因此 中的任何内容adjust MyMacro options都将覆盖任何默认设置和任何用户指定的设置。

下面的 MWE 得出：

而我希望代码生成：

笔记：

• 这个特定的宏有很多我可能想要覆盖的选项，所以我希望我不需要为此做特定的事情每个特定選擇。
