Editing your git history takes 3 main steps:

In order to import information about past commits in any project, Git History Editor asks you the result of your git log.

Because this log is made to be read by a program, it is formatted using the --pretty=format option of git log, then encoded to base64 to avoid problems with carriage returns or spaces.

Only the last 100 commits are imported, because a really huge commit history could drastically slow down your browser, or even make it crash.

The import command to run is the following:

git log -100 --pretty=format:"%H*#%an*#%ae*#%at*#%s" | base64 | tr -d "\n"

Git History Editor has a nice UI designed to let you edit what you want in each one of your past commits, or create a rule that will apply to multiple commits. Just try it.

When the edit step is finished, Git History Editor provides a script that you can run in order to apply the changes immediatly.

This script uses the git filter-branch command, which is the less painful way to rewrite a git branch history with precision.
