How do I set the email in Git by directory on Windows?

To set the email in Git by directory on Windows, you can leverage Git's local configuration settings. This allows you to use different email addresses for different projects, which is particularly useful for separating personal and work-related contributions.

Here's a step-by-step guide:

1. Navigate to Your Project Directory:

- Open your Command Prompt or PowerShell, and use the cd command to navigate to the specific project directory you want to configure. For example, if your project is in C:\Projects\my-project, you would type cd C:\Projects\my-project.

2. Set the Local Email Configuration:

- Use the git config command with the --local option to set the user's email address for this specific repository. For example, to set the email address to work.email@example.com, enter the following command:

git config --local user.email "work.email@example.com"

- This command will create or update the .git/config file within the current project directory, storing the email address specific to this repository.

3. (Optional) Set the Local User Name:

- It is also good practice to set a username for the project as well with:

git config --local user.name "Your Work Name"

4. Verify the Local Configuration:

- You can check the configured email address using the command:

git config --local user.email

- Or for the user name:

git config --local user.name

- Ensure that it matches the email address and user name you set in step 2 and 3.

5. Repeat for Other Directories:

- Repeat steps 1 through 4 for each directory where you want to use a different email address and user name. This way, each project can have its own specific user information.

6. Understanding Git Configuration Levels:

- Git has three configuration levels: System, Global, and Local. System-level configuration affects all users on the system. Global-level configurations apply to a specific user. And Local-level configurations are specific to individual repositories (as shown here). Local configurations take precedence over global and system settings. You can verify this with the command git config --list --show-origin to see what config takes precedence.

By using the --local option, you keep the email addresses and usernames associated with the specific projects they are meant for, allowing you to maintain a clean separation between personal and work or any other project types and their commmits.
