Git identity manager

This configures git to use an identity per local repository.

The idea is that the gitconfig enforces the identity to be chosen on a project-by-project basis. Enforce this by removing the user.name and user.email settings in your gitconfig, and replacing them with:

[user]
    useConfigOnly = true

Then add an identity with e.g.

git identity add --id github.personal --name "My Name" --email "test@example.com" [--signing-key "4AJGF02"] [--ssh-key ~/.ssh/id_rsa]

Identities can be listed with

git identity list

Selecting a git identity

For each project, git will not let you commit until you have chosen an identity. To do this, ensure that an identity is set up in your global .gitconfig, for example the line above adds the following to your .gitconfig:

[user "github.personal"]
    name = My Name
    email = test@example.com
    signingkey = 4AJGF02
    sshkey = ~/.ssh/id_rsa

Then the github.personal identity is available for selection.

Use git identity set in a project directory to interactively choose an identity.

An identity can be removed using git identity remove.

Generating shell completion

The command git identity gen-completion -s <shell> can be used to generate the correct auto-completion for your shell. It prints the completion information to stdout, so consult your shell's documentation for information on how to integrate this.
