BlameHim

Still feel shame while writting pieces of shit, and is afraid of being disclosed someday by git blame? Then it is for you.

Usage

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.

How it works

There are two modes in blamehim: hard-mode and soft-mode.

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.

how to undo

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~.

hard mode

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.

how to undo

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.

Example

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 [email protected] 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
