Sending Git Commits to Gmail: A Simple Guide

Have you ever wished you could easily share your latest Git commits with colleagues or clients directly from your terminal? While Git itself doesn't have built-in functionality for sending emails, there are tools like git send-email that can help you achieve this. This article will guide you through setting up git send-email to work seamlessly with Gmail.

The Problem: Sharing Git Commits Without Hassle

Sharing your latest code changes with collaborators can be a tedious process. You might copy and paste commit messages, create separate emails for each commit, or rely on external platforms like GitHub or GitLab. Wouldn't it be easier to send the commits directly to your desired recipients from your command line?

Setting Up git send-email with Gmail

1. Install git send-email: If you haven't already, you'll need to install git send-email. This is usually included with your Git installation, but you may need to enable it:

   git config --global sendemail.enabled true
   

2. Configure Your Email Client: We'll use msmtp to connect to Gmail, so install it:

   sudo apt-get install msmtp msmtp-mta
   

3. Create an msmtp.conf File: Create a configuration file in your home directory:

   sudo nano ~/.msmtprc
   

   And paste the following contents, replacing placeholders with your Gmail credentials:

   # Your Gmail username
   account default
   host smtp.gmail.com
   port 587
   auth on
   tls on
   user [email protected]
   password your_password
   

   Important: For security reasons, it is highly recommended to use an application-specific password for this configuration. You can generate one in your Gmail account settings.

4. Configure git send-email: Tell git send-email to use msmtp as its sending agent:

   git config --global sendemail.backend "smtp://localhost"
   git config --global sendemail.smtp.server "msmtp"
   

5. Send Your Commits: Now you can send your commits directly via email:

   git send-email --to [email protected] HEAD~5..HEAD
   

   This will send the last 5 commits to the specified recipient.

Additional Tips & Considerations:

• Subject Prefix: Use --subject-prefix to customize the email subject line (e.g., --subject-prefix "[Your Project Name]").
• Draft Mode: Use --draft to review the email before sending.
• Patch Format: By default, git send-email uses the "unified diff" format. You can change this using the --format option.
• Gmail Security: Be mindful of Gmail's security settings. You may need to enable "Less secure app access" for msmtp to work properly.

Conclusion

git send-email provides a streamlined way to share your code changes with collaborators. By leveraging Gmail and a simple configuration process, you can eliminate the need for manual copying and pasting. This can significantly enhance your workflow and communication efficiency. Remember to prioritize security by using an application-specific password and be aware of Gmail's security settings.
