Linking Visual Studio Code to GitHub on macOS: A Guide to Signed Commits

Integrating Visual Studio Code (VS Code) with GitHub on your macOS system not only enhances your coding and version control experience but also adds an extra layer of security and authenticity to your work by ensuring your commits are signed. This comprehensive guide will walk you through the necessary steps to establish a secure and efficient coding workflow.

1. Install Homebrew Dependencies

Before diving into configurations, let's install all necessary tools using Homebrew. This preemptive step aims to avoid common setup and troubleshooting issues later.

Install Git:

Git is essential for version control and GitHub integration.

brew install git

Install GPG for Commit Signing:

GPG adds an extra layer of security to your commits.

brew install gpg

Install pinentry-mac for GPG Passphrase Prompt:

pinentry-mac allows GPG to prompt you for your passphrase in a graphical window, avoiding common errors related to terminal input.

brew install pinentry-mac

Configure GPG to use pinentry-mac immediately after installation to ensure smooth operation:

echo "pinentry-program /opt/homebrew/bin/pinentry-mac" >> ~/.gnupg/gpg-agent.conf

Install Visual Studio Code:

VS Code is your main coding environment, integrated with Git and GitHub.

brew install --cask visual-studio-code

2. Configure Git with Your GitHub Credentials

Ensure your commits are linked to your GitHub account with proper configuration:

git config --global user.name "Your Name"
git config --global user.email "[e-mail]"

3. Setup GPG for Secure Commits

Generate a GPG key that you'll link to your GitHub account for secure commit signing:

gpg --full-generate-key

4. Add Your GPG Key to GitHub for Verified Commits

Export your GPG key and add it to your GitHub account for authentication:

gpg --armor --export <your-key-id>

Copy the output and add it to the "SSH and GPG keys" section in your GitHub account settings.

Configure Git to use your GPG key for signing commits:

git config --global user.signingkey <your-key-id>
git config --global commit.gpgsign true

5. Enhance VS Code with GitHub Integration

Install the "GitHub Pull Requests and Issues" extension from the Extensions view in VS Code to directly manage your repositories within the editor.

6. Authenticate VS Code with GitHub

Authenticate your GitHub account within VS Code to enable seamless repository management:

• Use Cmd+Shift+P to open the Command Palette.

• Execute "GitHub: Sign in to GitHub."

7. Finalize Your Setup

Restart the GPG agent to ensure all configurations are applied and effective:

gpg-connect-agent reloadagent /bye

Launch VS Code from a terminal session to ensure it inherits all necessary environment variables, avoiding common pitfalls related to GPG signing:

open -a "Visual Studio Code"

8. Test Your Setup

Create a test commit in VS Code, then verify its signature on GitHub to confirm that everything is set up correctly.

Optional: Use GitHub Desktop

For those who prefer a graphical interface for their Git operations, GitHub Desktop can be seamlessly integrated into your workflow:

brew install --cask github

Summary

This proactive approach aims to streamline your VS Code and GitHub integration on macOS, emphasizing security through GPG-signed commits and minimizing common setup errors. Remember to replace <your-key-id> with your actual GPG key ID, and ensure your GPG key's email matches your GitHub account email. For more detailed instructions and troubleshooting, consult the official documentation provided by GitHub and the VS Code team.
