我使用\input几个spreadtab来自这个答案在我的文档中直到我收到此错误：
TeX capacity exceeded, sorry [text input levels=15].
我在网上看到，我可以通过将这个参数从 更改为 来解决这个max_in_open = 15问题max_in_open = 30。
问题是我不知道在哪里可以找到进行更改的数据。我在 Mac 上使用 TeXStudio。
我正在寻找可以使我的文档正常工作的设置。

答案1
正如 David 在评论中指出的那样，代码\everyeof{\spreadtab@iv\noexpand} \expandafter\spreadtab@iv\@@input#2导致每个代码在完成之前\input都启动另一个代码\input，就 TeX 而言，这有效地嵌套了输入。
我真的不知道spreadtab，所以我没有一个好的解决方案。相反，这是一个非常非常非常非常非常非常非常，非常，非常使文档正常工作的糟糕方法。新spreadtabwithinput环境将用 的内容替换\input{<file>}其主体中的每个命令<file>，然后将所有内容传回spreadtab。您可以\input在其中放置任意多个命令。
继续需要您自担风险。

答案2
Heiko Oberdiek 即兴创作的包装捕获文件我想到的是。
您可以使用此包的宏从文件内容中定义宏。
我可以提供例行
\CatchFilesForScantokens{⟨comma-separated file list⟩}{⟨preamble code⟩}{⟨postamble code⟩}它读取并收集⟨前导码⟩以及每个文件的内容⟨逗号分隔的文件列表⟩和⟨邮寄代码⟩在 verbatim-catcode-regime 中，然后将收集/积累的东西传递到，以便\scantokens在逐字材料被重新标记时正常的 catcode-régime 生效。
您可以使用此例程作为
\CatchFilesForScantokens{⟨comma-separated file list⟩}%
{⟨stuff for initiating spreadtab-environment}%
{⟨stuff for ending the spreadtab-environment⟩}（每个文件内部都有⟨逗号分隔的文件列表⟩该例程使用\CatchFileDef包的宏捕获文件用于从该文件的内容中（重新）定义临时宏 A，以 verbatim-catcode/category-12-régime 进行标记，然后将该临时宏 A 的扩展附加到另一个临时宏 B 的定义中。⟨前导码⟩和⟨邮寄代码⟩也转到另一个临时宏 B。因此，所有内容都累积在另一个临时宏 B 中，其扩展可以\scantokens在正常的 catcode 制度下传递到该临时宏 B 进行重新标记。
我很懒，所以我使用 expl3 的函数\clist_map_inline:nn来解析⟨逗号分隔的文件列表⟩）。
以下是示例：

!!! 这种方法基于逐字分类代码机制读取/标记文件。因此，\input在⟨逗号分隔的文件列表⟩将不会执行。即，\input无法嵌套。您所能做的就是提供文件列表。!!!
!!! 它也依赖于读取和标记⟨前导码⟩和⟨邮寄代码⟩在逐字分类代码制度中。这反过来意味着\CatchFilesForScantokens
- 不能隐藏在任何宏的定义中，并且
- 不能在宏参数中使用，即
- 必须以这样的方式使用，确保在临时引入的类别代码制度的变化
\CatchFilesForScantokens生效时，通过从 .tex 输入文件中读取和标记内容来获取参数。

答案3
在许多 TeX 发行版中，存在一个名为 texmf.cnf 的文件。它通常位于texmf/web2c并包含上述参数。通常不建议乱用这种配置文件。但是，如果您的 TeX 支持此选项，则可以在命令行中使用开关进行设置--cnf-line='max_in_open=30'，例如：
lualatex --cnf-line='max_in_open=30' some-file.tex
许多编辑器支持针对项目或单个 TeX 文件的特殊命令行。例如，GNU Emacs 支持添加名为的文件局部变量，TeX-command-extra-options: "--cnf-line='max_in_open=30'"这样 TeX 文件的结尾可能如下所示：
% mode: latex
% TeX-master: t
% TeX-command-extra-options: "--cnf-line='max_in_open=30'"
% End:
