Git conditional user.email

I do have my global .gitconfig where I prefer to have my personal email address, and for every work related repository I used to do git config user.email [email protected] but there are always situations when I forget to do this.

Here comes the solution: includeIf that is available since git 2.13 and makes it a bit easier.

In my ~/.gitconfig I do have:

[includeIf "gitdir:~/D/canonical"]
  path = ~/D/canonical/.gitconfig

And under ~/D/canonical I simply have another .gitconfig where I set my user.email to my corporate email address. And voila, it will automagically apply a proper email for every git repository under configured path.

❯ cat ~/D/canonical/.gitconfig
[user]
  email = [email protected]
