我想使用辅助文件来读取和写入一些信息。
语境
在本例中，我使用此辅助文件来记录脚注格式中使用的宽度。实际上，我希望我的脚注编号右对齐，如下所示：
所以我需要知道提前（使用以前汇编的信息）最宽脚注编号的宽度（\@widthFootnoteNum对于“正常”脚注，\@mpwidthFootnoteNum对于小页面中的脚注）。
如果我只考虑“正常”脚注，则没有什么特别的问题。 的值在编译结束时\@widthFootnoteNum写入辅助文件（称为），并在下一次编译开始时读取。\jobname.foot
但是，如果我在 minipage 环境中对脚注执行相同的操作，事情就会变得复杂。辅助文件中写入了几个值，我必须读取此文件以找到正确的宽度，然后写入该文件以提供下一次并行编译的正确宽度。
我的测试没有定论...我设法写下了所有必要的信息，但之后我无法读取它。
平均能量损失
考虑以下 MWE：
一个包含 20 个“正常”脚注的简单文件和两个分别minipage包含 2 个和 7 个注释的环境。

我得到以下辅助文件：
6.704pt
11.40799pt
7.752pt
\@mpwidthFootnoteNum第一个值是第一个 minipage 环境的 的值。第二个值是第二个 minipage 环境
的 的值。第三个值对应于“正常”脚注 的 的值。\@mpwidthFootnoteNum\@widthFootnoteNum
因此我设法将下次编译所需的所有信息保存在辅助文件中。
问题
问题是我无法在编译时使用这些不同的值，因为辅助文件在同一编译过程中被连续读取和写入。因此每次新的写入都会覆盖该文件。
我们怎样才能解决这个问题？
我尝试过
我考虑过在编译开始时将所有值存储在一种编号列表中，从中可以取出最后一个值来赋值，\@widthFootnoteNum然后取出其他值来分配给不同\@mpwidthFootnoteNum的 minpage。目标是只需读取一次辅助文件。但我不知道该怎么做。
我尝试arrayjob通过将辅助文件放入数组来使用该包，但没有成功。
我还尝试使用两个辅助文件。文件A将用于编写@widthFootnoteNum各种@mpwidthFootnoteNum。在下一次编译开始时，文件A将被复制到一个文件中乙，它将在编译时读入并给出widthFootnoteNum和的值mpwidthFootnoteNum的值。同样，我还没有做到这一点，因为我似乎无法复制文件A进入文件乙。
最后，我尝试将应采用的不同值存储@mpwidthFootnoteNum在一个语法中ifcase #1 ...，其中#1表示环境的数量minipage。对于每个minipage环境，\@mpwidthFootnoteNum因此采用不同的值。

答案1
以下解决方案将脚注标签的宽度写入辅助文件，如\newfnwidth{0}{4.25006pt}、\newfnwidth{0}{8.50012pt}、\newfnwidth{1}{6.61023pt}等，其中0、1、2等标识我们是在 minipages 之外还是在1st、2nd 等 minipage 之内。处理辅助文件时，在文档开头计算脚注标签的最大长度。与往常一样，您必须运行 LaTeX 两次才能传播信息。
