How it works

Editing your git history takes 3 main steps:

Step 1: Import

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"

Step 2: Edit

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.

Step 3: Export

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.
