git log表示文件的一部分

Question

我想看到所有git提交影响了我的一个文件中当前行x-y的内容.有没有办法可以做到这一点？

Answer 1

现在git log支持-L像这样的选项git blame.这是在Git v1.8.4中添加的.

 -L <start>,<end>:<file>
 -L :<regex>:<file>

 Trace the evolution of the line range given by "<start>,<end>" (or
 the funcname regex <regex>) within the <file>. You may not give any
 pathspec limiters. This is currently limited to a walk starting from a
 single revision, i.e., you may only give zero or one positive revision
 arguments. You can specify this option more than once.

(git-log文档)

Answer 2

您可以使用git blame-L选项:

-L <start>,<end> 

 Annotate only the given line range. <start> and <end> can take one of these forms: 

 number 

If <start> or <end> is a number, it specifies an absolute line number (lines count from 1).

 /regex/ 

This form will use the first line matching the given POSIX regex. If <end> is a regex, it will search starting at the line given by <start>.

 +offset or -offset 

This is only valid for <end> and will specify a number of lines before or after the line given by <start>.

所以它将如下所示:

git blame -L 40,60 foobar

请注意,git blame显示每行的最新修订版.您也可以尝试使用该--reverse选项:

- 相反

走向历史而不是落后.这不显示出现一行的修订,而是显示一行存在的最后修订版.这需要一系列的修订,如START..END,其中指责路径存在于START中.

你也可以使用

gitk foobar
