给定行Git的函数名称

Question

Is there a way in git log to give it as input a line number of a file, and it return the function or class name.

Answer 1

In latest version (I'm not sure which version onward) of git, the option -L introduced. from this you can print the line changes. it will display the complete content of those lines. you can play with this option to print only range of revisions which explained here

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

Usage: (I don't have any php project, so tested with c Project)

tshetty@ubuntu:~/work/linux$ git log -L 44,44:arch/arm/common/scoop.c
