Remove private data when adding files to git

Info

git provides filters which you can access via your attributes and config files.

This is how to set up a simple clean filter.

Context

How It Works

The files git.config.sample and git.attributes.sample show lines you should add to your config and attributes files in order to make this work. Those files live at either .git/info/attributes (project-local) or .gitattributes (global), for attributes, and either .git/config (project-local) or .gitconfig (global), for config.

You will also need to put the full path of this clean script in your git config section.

Example

Your code looks something like this.

#GIT_CLEAN 555-555-5555 xxx-xxx-xxx
phone=555-555-5555
#GIT_CLEAN "secret string" xxxx
secet="secret string"

When added to your staging area, you will see.

phone=xxx-xxx-xxxx
secet="xxxx"
