Mercurial .hgignore 负向前瞻
使用 Mercurial，我需要忽略除名为“keepers”的某个目录中的文件之外的所有文件。
从表面上看，使用 Regex 和 Negative Lookahead 似乎很容易；然而，尽管我能够在 Regex Buddy 和其他工具中验证我的正则表达式，但在 TortoiseHg 中，它无法按预期工作。
文件：
- junk\junk.txt
- junk\text
- keepers\test\test
- keepers\test\test2\hi.txt
- keepersblah.txt
只有keepers下的两个文件不应该被忽略。
这是我希望起作用的正则表达式：
^(?!keepers/).+$
遗憾的是，这会导致所有文件被忽略。如果我将其更改为：
^(?!keepers).+$
它会按您的预期工作。也就是说，它会忽略任何不以 keeper 开头的文件/文件夹。但我确实想忽略以 keeper 开头的文件。
奇怪的是，如果我将其更改为：
^(?!keepers/).+\..+$
它将正确匹配文件夹，但如果它们没有扩展名，则不会忽略不在 keepers 文件夹中的文件。
任何建议将不胜感激。

Using Mercurial, I need to ignore all files except for those in a certain directory called "keepers".
On the face of things, this seemed easy using Regex and Negative Lookahead; however, although I am able to verify my regex in Regex Buddy and other tools, in TortoiseHg, it doesn't work as expected.
Files:
- junk\junk.txt
- junk\text
- keepers\test\test
- keepers\test\test2\hi.txt
- keepersblah.txt
Only the two files under keepers should be not be ignored.
Here is the regex I hoped would work:
^(?!keepers/).+$
Regrettably, this causes all files to be ignored. If I change it to:
^(?!keepers).+$
it works as you would expect. That is it ignores any files/folders that don't start with keepers. But I do want to ignore files that start with keepers.
Bizarrely, if I change it to this:
^(?!keepers/).+\..+$
It will properly match the folder, but it will not ignore files that are not in the keepers folder if they don't have an extension.
Any advice would be appreciated.

您的第一个表达式的问题是正则表达式还针对“keepers”本身进行了测试。这种情况可以添加一个附加条件：
或（不太紧凑，但更容易理解）：
The problem with your first expression is that the regex is also tested against "keepers" itself. That case can be added with an additional condition:
or (less compact, but simpler to understand):
