identity

A tool for managing your identity from the command line.

If you have more than one identity, such as work and personal, on the same machine then identity can help. It currently supports Git and Cargo. The usage of each is described below. If you prefer, there is a set of functional tests provided with the source code.

Configuring identities

The identity CLI looks for a configuration file at ~/.config/identity.toml. You can create or upgrade your identity file using identity --verify.

version = "1.0"

[[identity]]
id = "personal"
email = "your-email@example.com"

[[identity.account]]
service = "git"
user = "my-username"
match_url = "https://github.com/my-username/*"
description = "my personal github"

[[identity.account]]
service = "cargo"
user = "my-username"
token = "a-token"

[[identity]]
id = "work"
email = "your-email@company.com"

[[identity.account]]
service = "git"
user = "company-username"
match_url = "https://github.com/company-username/*"
description = "my work github"

This configures two identities, personal and work. The personal identity has a GitHub account and a Cargo (crates.io) account. The work identity just has a GitHub account.

Git

Your username and email address are the first thing to keep separate. Git gives you several options for configuring these and you can use identity to find out what's currently being used

identity whoami --service git

Note: You can omit the --service git argument and you will be prompted instead.

This will output something like

user.name  = ThetaSinner
user.email = your-email@example.com

Knowing is one thing, but preventing commits with the wrong user information is the goal. While in a Git repository run

identity git install

which will install a pre-commit hook to verify your identity on every commit. The origin URL will be matched against the identities in your configuration file, and if the current Git identity isn't the same as the matched on, the commit will be prevented.

If you're already using pre-commit hooks then you can add the check manually by putting identity git hook --pre-commit into .git/hooks/pre-commit.

To check that a repository is currently configured to use identity and that the identity is configured correctly you can run

identity git --check

Cargo

Cargo doesn't have accounts in the same sense. You have a token which can be used to publish crates and this is your identity as far as identity is concerned.

To check your current identity, use

identity whoami --service cargo

Or to switch to a new identity

identity switch --service cargo

which will prompt you for an identity to switch to.

Other service

I plan to add more services as I need them, feel free to open an issue or a PR on GitHub if you'd like something else supported.
