不使用 edef 即可在宏中启动宏外持续存在的命令

在薛定谔猫的帮助下，我能够创建一个制作立方体块棱镜的宏。我还希望能够在宏中启动宽度、高度、深度的定义，以便继续在表格中进行计算。我不能把表格放在宏中，因为我并不总是需要计算（对于学生来说它是空白的）

这是我的代码：

我想要得到：带桌子的立方体

我遇到的问题是，它说命令、宽度、高度和深度已经定义，而我之所以遇到这个问题，是因为我的宏想要再次定义它们。我想知道如何修复我的宏来定义宽度、高度和深度，并让这些定义在特定问题中保留在体积宏中。也许像 Steven 建议的那样，使用\let和\relax函数？- 但我不知道该怎么做。

我之所以觉得我必须包含宽度、高度、深度的定义为，如果不这样做，\volume似乎没有参数，因为我只能猜测，它无法从 cubeblocks 宏中提取这些值（但我确实希望他们从 cubeblocks 宏中提取值）我应该提到，我将针对不同的学生问题使用不同的值重复 cubeblocks 宏。

我不知道该怎么做。总结：1. 使用 cubeblocks 宏 2. 让宏使用\volumecubeblocks 宏的宽度、深度、高度值 3. 使用正确的范围重复其他问题。

谢谢大家，我也非常感谢大家对我的代码做出的任何建议。

答案1

由于所有操作都发生\cubeblocks在 中\resizebox，而 又在某个局部范围内排版一个框，而该框本身也形成一个局部范围，因此如果没有一些全局分配，你就无法摆脱它。

您可以在当前范围/当前组内使用宏进行重新定义/“（重新）初始化” ，并根据键的值 /  ​/ ​：\pgfkeysgetvalue{⟨full key⟩}{⟨macro⟩}\Width\Depth\Height/tikz/cubeblocks/w/tikz/cubeblocks/d/tikz/cubeblocks/h

\pgfkeysgetvalue{/tikz/cubeblocks/w}{\Width}将（在当前范围/组内）（重新）定义宏\Width来扩展为形成键值的标记/tikz/cubeblocks/w。

\pgfkeysgetvalue{/tikz/cubeblocks/d}{\Depth}将（在当前范围/组内）（重新）定义宏\Depth来扩展为形成键值的标记/tikz/cubeblocks/d。

\pgfkeysgetvalue{/tikz/cubeblocks/h}{\Height}将（在当前范围/组内）（重新）定义宏\Height来扩展为形成键值的标记/tikz/cubeblocks/h。

如果您不介意全局重新定义\Width、\Depth和\Height，您可以执行\global\let\Width=\Width、\global\let\Depth=\Depth和\global\let\Height=\Height从限制在当前范围/组的重新定义中进行全局分配 - 全局分配不仅限于当前范围/组，而且适用于所有上级范围/组也。

（分配在执行分配时具有的含义。以 为前缀的结果是分配不仅限于当前范围/组，而且还适用于所有上级范围/组。）\let⟨control-sequence-token⟩=⟨token⟩⟨control-sequence-token⟩⟨token⟩\let\global

如果您希望\Width、\Height和\Depth仅在当前范围内重新定义，则可以全局定义一个临时宏来在临时宏扩展的范围内重新定义\Width、\Height和，然后在重新定义、和的范围内调用该临时宏。\Depth\Width\Height\Depth

\Width如果这样做，您需要确保、\Height和的值得\Depth到正确扩展。

\edef根据问题的主题，不使用是前提条件。
因此我建议使用\romannunmeral0-expansion 作为扩展控制的手段。

-expansion的要点\romannunmeral0是：

\romannueral工作原理如下：\romannumeral触发 TeX 将 TeX- 转换⟨number-quantitiy⟩为类别代码 12（其他）的字符标记序列，以⟨number-quantitiy⟩小写罗马符号表示所讨论的 TeX-。

如果 TeX “发现” 要转换的数字不是正数（例如数字 0），则构成该 TeX- 的标记⟨number-quantitiy⟩将被默默“吞掉”，并且不会传递任何标记。

TeX 将在搜索属于相关 TeX 的更多数字⟨number-quantitiy⟩或终止搜索更多数字的内容时扩展可扩展标记。

与终止搜索更多数字的其他事物不同，终止数字序列的空格标记将被默默丢弃。

所有这些意味着，您可以很好地（ab？）使用\romannumeral它来触发大量的扩展工作并翻转宏参数，只要确保在完成所有扩展工作之后⟨number-quantitiy⟩找到一个值不是正值的 TeX- 即可。

我倾向于按如下方式执行此操作：搜索更多数字，从而通过 触发扩展事物\romannumeral0。完成所有扩展和参数翻转工作后，标记流中的下一个标记将是空格标记。因此会找到非正数 0，从而导致 TeX-⟨number-quantitiy⟩被默默吞噬，而不会提供标记作为回报。空格标记被丢弃。
