我如何“混淆责任”？删除的行？ [英] How do I "git blame" a deleted line?

问题描述

git blame 非常适合修改和添加行，但是如何才能找到何时存在于特定以前提交中的行最终被删除。我正在考虑 bisect ，但我希望有更便利的方式。 $ b

[在你问之前：我只是做了一个 git log -p 并搜索了代码行，（a）一些白痴已经删除了以前的关键代码行 提交和（b）我是那个白痴]

解决方案

如果您知道该行的内容，这是一个理想的用例for：

  git log -S  path / to / file 
  

它显示你提交哪个引入或删除该字符串的实例。还有 -G< regex> ，它对正则表达式做同样的事情！查看 man git-log 并搜索 -G 和 -S $ b

-S 选项或镐（这些功能的友好名称）选项实际上在 git-blame 手册页的标题中提到，在描述部分中，它使用 git log -S来举例说明。 .. 。

git blame is great for modified and added lines but how can I find when a line that existed in a specific previous commit was eventually deleted. I'm thinking bisect but I was hoping for something handier.

[ before you ask: in the case, I just did a git log -p and searched through for the code line and (a) some idiot had just deleted the vital line in the previous commit and (b) I was that idiot ]

解决方案

If you know the contents of the line, this is an ideal use case for:

git log -S <string> path/to/file

which shows you commits which introduce or remove an instance of that string. There's also the -G<regex> which does the same thing with regular expressions! See man git-log and search for the -G and -S options, or pickaxe (the friendly name for these features) for more information.

The -S option is actually mentioned in the header of the git-blame manpage too, in the description section, where it gives an example using git log -S....
