Git diff:忽略以单词开头的行 [英] Git diff: ignore lines starting with a word

问题描述

正如我在此处所了解的那样，我们可以使用以下命令告诉git diff忽略以*开头的行:

As I have learned here, we can tell git diff to ignore lines starting with a * using:

git diff -G '^[[:space:]]*[^[:space:]*]'

如何告诉git忽略以一个单词或更多单词(例如:* Generated at)开头的行，而不仅仅是一个字符?

How do I tell git to ignore lines starting with a word, or more (for example: * Generated at), not just a character?

该文件将被忽略，它仅包含一些琐碎的更改:

This file shall be ignored, it contains only trivial changes:

- * Generated at 2018-11-21
+ * Generated at 2018-11-23

该文件不应被忽略，它不仅包含微不足道的更改:

This file shall NOT be ignored, it contains NOT only trivial changes:

- * Generated at 2018-11-21
+ * Generated at 2018-11-23
+ * This line is important! Although it starts with a * 

推荐答案

Git正在使用 POSIX 似乎不支持环视的正则表达式.这就是 @Myys 3的方法不起作用的原因.一个不太优雅的解决方法可能是这样的:

Git is using POSIX regular expressions which seem not to support lookarounds. That is the reason why @Myys 3's approach does not work. A not so elegant workaround could be something like this:

git diff -G '^\s*([^\s*]|\*\s*[^\sG]|\*\sG[^e]|\*\sGe[^n]|\*\sGen[^e]|\*\sGene[^r]|\*\sGener[^a]|\*\sGenera[^t]|\*\sGenerat[^e]|\*\sGenerate[^d]).*'

这将过滤掉所有以"* Generated"开头的更改.

This will filter out all changes starting with "* Generated".
