将多个逗号分隔的 TikZ 选项传递给单个 keyval 键

Question

我仍在改进我的回答需要帮助从 TikZ 中的一组 2D 节点创建 3D 立方体其中一个选项应该是强调长方体的边缘。这意味着例如

\draw[red, very thick, dashed] <some coordinates>

我用它keyval来定义长方体的参数。现在我的问题是，如何将所有这些命令传递给一个键？我会这样做：

\tikzcuboid{%
        emphedge=Y,%
        emphstyle=very thick,
    }

我只能传递一个选项（此处very thick），因为其他逗号（例如very thick, red, dashed）被解释为键的分隔符keyval。我尝试了几种方法，例如

emphstyle={very thick, red, dashed}
emphstyle=style={very thick, red, dashed}
emphstyle=(very thick, red, dashed)

所以我的问题基本上是：是否有某种特殊的分隔符，keyval我可以将逗号分隔的参数列表放入其中？但是，这些特殊分隔符不应传递，因为这可能会导致出现问题TikZ。

Answer 1

为了保护代码中的逗号，你可以这样做

\ifthenelse{\equal{\tikzcuboid@emphedge}{Y}}%
    {\protected@edef\cube@temp{%
\noexpand\draw[\tikzcuboid@emphstyle](0,\dimy,0) -- (\dimx,\dimy,0) -- (\dimx,\dimy,\dimz) -- (0,\dimy,\dimz) -- cycle;     
\noexpand\draw[\tikzcuboid@emphstyle] (0,\dimy,\dimz) -- (0,0,\dimz) -- (\dimx,0,\dimz) -- (\dimx,\dimy,\dimz);
\noexpand\draw[\tikzcuboid@emphstyle](\dimx,\dimy,0) -- (\dimx,0,0) -- (\dimx,0,\dimz);
      }\cube@temp   
    }%
    {}

结果

\tikzcuboid{%
    shiftx=16cm,%
    shifty=8cm,%
    scale=1.00,%
    rotation=0,%
    densityx=2,%
    densityy=2,%
    densityz=2,%
    dimx=4,%
    dimy=4,%
    dimy=4,%
    linefront=green!75!black,%
    linetop=green!50!black,%
    lineright=green!25!black,%
    fillfront=green!25!white,%
    filltop=green!50!white,%
    fillright=green!75!white,%
    emphedge=Y,%
    emphstyle={very thick, red, dashed}
}

Answer 2

如果您愿意改用，\pgfkeys那么这很简单。可以将一个键声明为键列表的别名。这可以通过以下方式完成：

\tikzset{my key/.style={list,of,other,keys}}

然后密钥以适当的方式my key扩展为。list,of,other,keys

以下是基于链接问题中的代码的操作示例。我在键名中添加了一些空格以使其更容易使用（这意味着我看到了一些错误：您曾多次dimy将 替换为）。我用布尔键替换了 。我还将和键压缩为一种样式，以提供更大的灵活性。您可以用简单的替换以获得最大的灵活性，然后可以随意填充或不填充网格。dimz\ifthenelselinefill\filldraw\path

代码如下：

\documentclass[parskip]{scrartcl}
\usepackage[margin=15mm,landscape]{geometry}
\usepackage{tikz}
