Still feel shame while writting pieces of shit, and is afraid of being disclosed someday by git blame? Then it is for you.
blamehim is a simple shell script that can change the author of lines to someone you specified. Thanks to git's loose permission management, you can disguise as anybody if you know his username and email address, and making it even easier, blamehim will do it for you. When someone blame this file, they will see the victim's name rather than yours.
There are two modes in blamehim: hard-mode and soft-mode.
It is simple. blamehim apends a space to lines you specified, temporarily changes user.name and use.email to your victim's, makes commit, restores your own username and email address, done.
In soft-mode, blamehim just append an extra fake commit and won't hurt existing history, so it is safe. You can simply undo it by git reset --hard HEAD~.
Unlike soft-mode, hard-mode use git filter-branch to rewrite almost entire history if necessary. blamehim run in soft-mode by default, use -f to enable hard-mode, like
blamehim -f -a badguy 1-$ file
Remember that hard-mode may cost a pretty long time to complete.
You can find your original branch header under .git/refs/original, or refer to git reflog. If you found it, git reset will do the job.
First I have a file and blamed like this:
f8d5ce00 (dyng 2013-08-01 23:55:22 +0900 1) foo
f8d5ce00 (dyng 2013-08-01 23:55:22 +0900 2) bar
f8d5ce00 (dyng 2013-08-01 23:55:22 +0900 3) foo
Then I run script like this:
blamehim -a badguy -e badguy@badguys.com 1-$ file
Here is the blame result after things done:
d009b43c (badguy 2013-08-02 00:02:41 +0900 1) foo
d009b43c (badguy 2013-08-02 00:02:41 +0900 2) bar
d009b43c (badguy 2013-08-02 00:02:41 +0900 3) foo
