How to switch git email based on host?-CodePudding

I have accounts in three different Git service providers - GitHub, GitLab and BitBucket. I want to ensure that my commits are signed via SSH in all of the mentioned providers, which is not possible since I have assigned a GitLab email at the moment, and all of my accounts use unique emails. This only verifies signed commits for GitLab successfully. How do I make it so that GitHub/BitBucket repositories will be assigned to their respective email?

Haven't found anything online that deals with this. There is a "gitdir" method, but I am not looking for this. I am expecting that Git understands what host I am using (if on GitHub, use [email protected], if on GitLab, use [email protected] and so on), and based on that, assign emails.

Git allows you to set the default email address for new commits in a local repository clone via the following command:

$ git config --local user.email "[email protected]"

So as long as any given local repository of yours is only pushing to a given hosting service, then you should be able to assign the appropriate email to the commits.

Does that answer your question?

Unfortunately, Git config does not support conditionals directly, but includes other config files. I was able to resolve my issue by using hasconfig:remote.*.url condition for includeIf. You may remove the email variable under [user] block - this is your global email. Create three new blocks:

.gitconfig

...
[includeIf  "hasconfig:remote.*.url:[email protected]:**/**"]
path = .github
[includeIf  "hasconfig:remote.*.url:[email protected]:**/**"]
path = .gitlab
[includeIf  "hasconfig:remote.*.url:[email protected]:**/**"]
path = .bitbucket
...

Now create three config files .github, .gitlab and .bitbucket:

github

[user]
  email = [email protected]

gitlab

[user]
  email = [email protected]

bitbucket

[user]
  email = [email protected]
