I have a need to use different git config for different projects, here’s how I do it.

Let say I have 2 folders, one for my daily work projects and the others for my personal project (like this blog).

Split the configurations into 2 files, let’s name it .gitconfig-work and .gitconfig-personal.

Here’s .gitconfig-work:

[user]
	name = Dwi Wahyudi
	email = dwi.wahyudi@work-email.com

Here’s .gitconfig-personal:

[user]
	name = Dwi Wahyudi
	email = dwi.wahyudi@personal-email.com

This is so that when I commit on my work projects git uses my work email, and when I work on my personal project git uses my personal email. And here’s .gitconfig:

[includeIf "gitdir:~/Projects/"]
    path = .gitconfig-work
[includeIf "gitdir:~/dwahyudi.gitlab.io/"]
    path = .gitconfig-personal
[includeIf "gitdir:~/personal-projects/"]
    path = .gitconfig-personal
