TeX Live 2020 从 2018 更新后出现的问题

以下命令在 TeX Live 2018 上运行良好，但在更新到 TeX Live 2020 后，出现此错误。我找不到问题所在：

答案1

这是一个有意改变钛钾Z 因为否则你通常会丢失无点的 i 和 j 字符，因为\i和\j经常用作循环变量\foreach。

要在循环结束后使用循环中的最后一项，您可以\xdef\lastj{\j}在内部添加\foreach，然后在外部使用\lastj。

答案2

这个答案解释了导致问题的 pgf 更改之一。但是，还有另一个更改允许您将计数偷运出组：\pgfutil@pushmacro和\pgfutil@popmacro。虽然我不确定是否要使用\i和\j作为计数器，但您可以使用上述宏将宏偷运出循环foreach。这些技巧可以更广泛地用于将您需要的任何内容从由生成的本地组中导出\foreach。
