When committing to a Git repository related to my consulting work, I must use my company e-mail address, kirill@cynkra.com. Not so much for my open-source work – for this, I prefer to use other e-mail addresses, like krlmlr+r@mailbox.org . (For example, Travis CI sends notification e-mails to the committer’s e-mail address, and I have set up filtering for that other address.)

Having to configure the e-mail address for each repository separately eventually gets annoying. Instead, I’d rather have all repos within a specific subdirectory use particular e-mail address.
All my Git repos live in ~/git. Subdirectories R and cynkra,
contain R packages and repos related to consulting, respectively. To
achieve the desired setup, I edit my ~/.gitconfig with the following
entry:
[includeIf "gitdir:git/**"]
path = git/.gitconfig
This ensures that all repos in the git directory use the
git/.gitconfig file in addition to the main configuration. That file
contains the following:
[includeIf "gitdir:R/**"]
path = R/.gitconfig
[includeIf "gitdir:cynkra/**"]
path = cynkra/.gitconfig
Finally, in ~/git/R/.gitconfig and ~/git/cynkra/.gitconfig, I
configure the e-mail addresses I want to use for all repos pertaining to
R and cynkra, respectively.
[user]
email = ...
I verify the setup with git config -l | grep user. Indeed, cynkra
repos use the cynkra e-mail address. Voilà!
The above approach requires a recent-ish version of git- version 2.14
or later should suffice. Read more about conditional
includes.
