Git with Multiple Email Addresses

Why not just create a new user? I feel that this warrants some isolation.

This allows having everything just under ~/Projects and having special configs without too much hassle IMO, it seems cleaner than using branching configs. You can still symlink the shared bits.

To work you just `su $WORK/SCHOOL_USER` to get a simple shell, use ssh+tmux to get a session, and can use editors/browsers/etc configured specifically for that user (purpose). In case you want more uniformity when editing you can use tramp (or something similar).

Different addresses for different repos are pretty straightforward. Can someone tell me please how to use multiple SSH keys. I have constant problem with Bitbucket because they require SSH key to be unique across whole platform. I work on many projects. Some companies require me to use Bitbucket account created by them with their email address. I can't add my SSH key to such account because it's already assigned to my private account. My workaround is to use GitKraken which allows assigning SSH keys per repo but I would really like to have this option in command line and don't need full GitKraken license just for pushing changes

There's an option in newer git. For cloning new repo:

git clone -c "core.sshCommand=ssh -i ~/.ssh/bitbucket-work -F /dev/null" git@bitbucket.com:example/example

For existing repo:

git config core.sshCommand "ssh -i ~/.ssh/bitbucket-work -F /dev/null"

Where "bitbucket-work" is the name of the key for that particular repo.

You can use something like direnv to export GIT_SSH to point at a wrapper that invokes `ssh -i ~/.ssh/id_corp $@`.

I tend to just configure my .ssh/config file to create an entry for github-companya with host github.com and identity file ~/.ssh/companya (or replace GitHub with bitbucket in your case)

I do it like this: https://gruchalski.com/posts/2022-04-28-private-go-modules-w....

This is in the context of go modules but it works with regular git stuff.

On BitBucket, at least, you can utilize wildcard DNS and use different hostnames with SSH keys.

$ git clone git@workspace.bitbucket.org:workspace/repo.git

I haven't tried with GitHub as I only have one account I use there.

I similarly have multiple git accounts and repos. When I clone a repo i do so via SSH. When I am in the folder of one repo (say a GitHub.com repo) then the ssh account that cloned the repo is used.

I'm not near my laptop, but it's two lines of code in the SSH config files and that's it.

Does anyone follow a similar pattern?

Please provide these two lines, I'd love to utilize the same pattern in the future :)

Stuff in ~/.ssh/config which complements the git config in OP:

  Host foo.bitbucket.org
    HostName bitbucket.org
    User git
    IdentityFile ~/.ssh/foo_id

As in, for using bitbucket.org with the private key ~/.ssh/foo_id, you'd instead clone from foo.bitbucket.org:owner/repo.

...or just set email per repository and leave it empty in the global config?

My answer to this is `direnv` and silo-specific subdirs where I set the git email ENV variables so that all projects default to the right email. Work quite well. I also keep my AWS_PROFILE setting and a few more things in those silo-specific `.envrc` files.

I use this: https://memooo.ooo/posts/git-multiple-identities/

There’s also an easy emacs package for that.

https://github.com/akirak/git-identity.el

Yes, but the solution of the original post does not need additional tools. I.e. it works in- and outside of emacs.

There's karn: https://github.com/prydonius/karn which does a decent job of managing git identities based on folder location, configurable via yarn file
