Directory-specific Git email address

This solution allows Git identities to be separated across different work areas. For example, I use it to separate my personal projects from my university projects.

First, set a default identity in the global Git configuration file. Then, add an includeIf section to apply the configuration file specified in path to all repositories in ~/repos/uni/:

[user]
    name = Jane Doe
    email = personal@example.com
[includeIf "gitdir:~/repos/uni/"]
    path = ~/repos/uni/.gitconfig

In the specified path file, set the new Git identity:

[user]
    name = Jane Doe
    email = uni@example.com

Now all repositories in ~/repos/uni/ use the university email address, while others use the default identity.
