Git users with multiple identities – for ex. work vs personnal projects – rejoice, there is now an easy way to set different user.email & user.name per directory structure: use a conditional include in your global .gitconfig
[includeIf "gitdir:/path/to/your/work/top/dir/"] path = /path/to/your/work/top/dir/customconf.inc
All projects under that directory will pick up user config set in the custom conf overriding the thus global one.
I think it’s since Git 2.13
