Question

这里我使用了三个宏，，\a它们被捕获到中。我测量了的高度，并将其结果设置为高度寄存器。\b\c\BODY\BODY\nodeboxht

这确保所有盒子的高度与最高盒子的高度相匹配。

测量的高度\BODY有负面影响。如果\BODY包含计数器，它将在测量步骤中递增，然后在排版步骤中再次递增。这会产生不想要的偶数。我可能可以用一些\ifnum逻辑来解决这个问题，但我想知道是否有更好的方法。

输出

计数器用 0 初始化。数字 1、3 和 5 是不可见的，因为它们在第一次\BODY调用时出于测量目的进行了扩展。

我的解决方案

使用全局 TeX 寄存器（LaTeX 计数器），我可以将其用作 TRUE / FALSE 指示器。这完全是黑客行为。

\newcount\counterTF% TeX Register init
\global\counterTF=0\relax% TeX Counter Definition Equivalent of LaTeX

% Redefine with logic such that it only steps and uses counter every other call
\gdef\typesetcounter{\ifnum0=\counterTF\relax\global\counterTF=1\else\stepcounter{boxcount}\arabic{boxcount}\global\counterTF=0\fi}

Answer 1

这里，我在执行 之前重新定义\typesetcounter为（仅用于垂直测量）。设置 之后，我重新定义为您想要的值（增加并排版计数器）。\relax\sbox\sbox\typesetcounter
