Set author per repository

Question

I work on both work and personal projects on my machine, and for my work projects, I prefer to use my work email, and vice versa.

In shell, I use direnv to set GIT_COMMITTER_EMAIL and GIT_AUTHOR_EMAIL.

How do I achieve something like this in magit?

Answer 1

One way to do this is to set the author configuration in .git/config in each repository, in the same format as in ~/.gitconfig, i.e.:

[user]
    name = My Name
    email = [email protected]

Answer 2

you can do this with one-time git configuration. you can use it for email and so on, but also for using a different ssh key:

in ~/.gitconfig:

[includeIf "gitdir:~/work/"]
path = .gitconfig_work

in ~/.gitconfig_work:

[user]
email = …

[core]
sshCommand = ssh -i ~/.ssh/id_…_work -o 'IdentitiesOnly yes'

explanation: this makes git use another configuration, which specifies email and a ssh key (which you should create with a different filename and then add to your github account) when running git anywhere below the ~/work directory. in practice, this one time configuration makes it work for all current and future clones.

Answer 3

Anoter useful option is the git-identity package.

From its README:

This Emacs package lets you manage local Git identities, i.e. user.name and user.email options in .git/config, inside Emacs. It can be useful if you satisfy all of the following conditions:

- You have multiple Git identities on the same machine(s).
- You use Emacs.
- You (almost always) use magit for Git operations on your machine(s).

Answer 4

Same effective answer as @legoscia, but instead of modifying the file, I find that if you do

git config user.email [email protected]
git config user.name "My Name" 

It sets the local config, i.e .git/config

If you add the flag --global then it modifies your global config.

Thus you can have different name/email setup per repository, and can even check them by running git config user.email. When called without any arguements, it works as a GET command.
