解决 Mathematica Notation 错误的方法？
Mathematica 提供了 Notation 包来定义自定义符号，它似乎工作得很好，直到我将带有自定义符号的笔记本保存为包并尝试使用 Needs["..."] 导入新的符号。正如 Mathematica 邮件列表 中所述，这会导致奇怪的语法错误在评估对 Notation[] 的任何调用时。建议的解决方案是手动打开符号笔记本并将其评估到内核中，但这对于我计划分发的文件来说是一个痛苦。如果有人有更好的解决方法来解决该问题，我将非常感谢您的帮助！
Mathematica offers the Notation package to define custom notation, and it seems to work great until I save a notebook with custom notation as a package and try to use Needs["..."] to import the new notation. As documented on the Mathematica mailing list, this causes bizarre syntax errors when evaluating any call to Notation[]. The suggested solution is to manually open the notation notebook and evaluate it into the kernel, but this is a pain for files that I plan on distributing. If anyone has a better workaround for the problem, I'd really appreciate the help!

我认为你的问题在于 Mathematica 处理
Notation[]的方式，引用：可能根本不可能有一个包文件调用
Notation[]，但建议使用 ParsedBoxWrapper 我现在没有时间玩。对于您的问题，有一种笨拙的解决方案，即您将所有
Notation[]分配放入笔记本的一个单元格中，并将其设为初始化单元格（右键单击单元格边缘 -->初始化单元）。顺便说一句，这还会创建一个仅包含该单元格内容的 .m 文件（但遗憾的是，该文件无法与Needs[]或<<一起使用） 。之后，您可以折叠单元格，使其不可编辑、不可评估，然后嘿，快点！和你想要的差不多。我应该注意到，从分发的角度来看，这种拼凑相当不错，因为每次加载主文件时都会重新生成 .m 文件，因此您不需要发送多个文件。唯一的缺点是笔记本有点丑（即一个隐藏单元），并且每当您第一次评估该笔记本中的某些内容时，都会弹出一个窗口询问您是否要评估该笔记本的初始化单元。
I think your problem lies in the way Mathematica treats
Notation[], quote:It may not be possible at all to have a package file call
Notation[], but there is a suggestion of using ParsedBoxWrapper which I didn't have time to play around with right now.There is a kludgy solution to your problem, which is that you put all the
Notation[]assignments into one cell of the Notebook and make it an initialization cell (right click on the cell edge --> Initalization Cell). This will incidentally also create a .m file with just the contents of that cell (but this file will, alas, not work withNeeds[]or<<). After that you can collapse the cell, make it uneditable, unevaluatable, and hey presto! Almost like what you want.I should note that from a distribution point of view this kludge is rather nice since the .m file gets regenerated every time you load the main file so you don't need to ship multiple files. The only downside is a slightly ugly Notebook (i.e. one hidden cell), and a pop up asking whether you want to evaluate the initialization cells of the Notebook whenever you first evaluate something in that Notebook.
