Why Git-ripper?

Have you ever needed just a single component from a massive repository? Or wanted to reference a specific configuration directory without downloading gigabytes of code? Git-ripper solves this problem by letting you extract and download only the folders you need, saving bandwidth, time, and disk space.

Features

• Selective Downloads: Fetch specific folders instead of entire repositories
• Resume Interrupted Downloads: Automatically resume downloads that were interrupted or failed
• Progress Tracking: Visual progress indicators with file-by-file download status
• File Integrity Verification: Ensures downloaded files are complete and uncorrupted
• Directory Structure: Preserves complete folder structure
• Custom Output: Specify your preferred output directory
• Branch Support: Works with any branch, not just the default one
• Archive Export: Create ZIP archives of downloaded content
• Checkpoint Management: View and manage saved download progress
• Simple Interface: Clean, intuitive command-line experience
• Lightweight: Minimal dependencies and fast execution
• No Authentication: Works with public repositories without requiring credentials

Authentication (Private Repositories & Rate Limits)

To download from private repositories or to increase your API rate limit, you need to provide a GitHub Personal Access Token (PAT).

How to Generate a Token

You can use either a Fine-grained token (Recommended) or a Classic token.

Option A: Fine-grained Token (Recommended)

1. Go to Settings > Developer settings > Personal access tokens > Fine-grained tokens.
2. Click Generate new token.
3. Name it (e.g., "Git-ripper").
4. Resource owner: Select your user.
5. Repository access: Select Only select repositories and choose the private repository you want to download from.
6. Permissions:
   • Click on Repository permissions.
   • Find Contents and change Access to Read-only.
   • Note: Metadata permission is selected automatically.
7. Click Generate token.

Option B: Classic Token

1. Go to Settings > Developer settings > Personal access tokens > Tokens (classic).
2. Click Generate new token > Generate new token (classic).
3. Give your token a descriptive name.
4. Select Scopes:
   • For Private Repositories: Select the repo scope (Full control of private repositories).
5. Click Generate token.

Using the Token

Pass the token using the --gh-token flag:

git-ripper https://github.com/username/private-repo/tree/main/src --gh-token ghp_YourTokenHere

Security Note: Be careful not to share your token or commit it to public repositories.

Examples

Extract a Component Library

# Download React DOM package
git-ripper https://github.com/facebook/react/tree/main/packages/react-dom

Get Configuration Files

# Extract VS Code build configuration
git-ripper https://github.com/microsoft/vscode/tree/main/build -o ./vscode-build-config

Download Documentation

# Get Node.js documentation
git-ripper https://github.com/nodejs/node/tree/main/doc -o ./node-docs

Copy UI Templates

# Extract Tailwind components
git-ripper https://github.com/tailwindlabs/tailwindcss/tree/master/src/components -o ./tailwind-components

Download from Private Repository

# Download from a private repository using a token
git-ripper https://github.com/my-org/private-project/tree/main/src --gh-token ghp_abc123...

Download and Create Archive

# Download React DOM package and create a ZIP archive
git-ripper https://github.com/facebook/react/tree/main/packages/react-dom --zip

# Extract VS Code build configuration with custom archive name
git-ripper https://github.com/microsoft/vscode/tree/main/build --zip="vscode-build.zip"

Resume Downloads

Git-ripper now supports resuming interrupted downloads, making it perfect for large folders or unstable network connections.

Automatic Resume (Default Behavior)

# Start a download
git-ripper https://github.com/microsoft/vscode/tree/main/src/vs/workbench

# If interrupted (Ctrl+C, network issues, etc.), simply run the same command again
git-ripper https://github.com/microsoft/vscode/tree/main/src/vs/workbench
# It will automatically resume from where it left off

Force Restart

# Ignore any existing progress and start fresh
git-ripper https://github.com/microsoft/vscode/tree/main/src/vs/workbench --force-restart

Disable Resume

# Use traditional behavior without resume functionality
git-ripper https://github.com/microsoft/vscode/tree/main/src/vs/workbench --no-resume

Manage Checkpoints

# List all saved download progress
git-ripper --list-checkpoints

# Output shows:
# 1. ID: a1b2c3d4
#    URL: https://github.com/microsoft/vscode/tree/main/src/vs/workbench
#    Progress: 45/120 files
#    Last Updated: 2025-06-04T10:30:00Z

Resume Features

• Automatic Progress Saving: Downloads are checkpointed every few files
• File Integrity Verification: Ensures existing files are complete and valid
• Smart Recovery: Detects corrupted or incomplete files and re-downloads them
• Multi-Download Support: Manage multiple concurrent download projects
• Progress Indicators: Visual feedback showing completed vs remaining files

How It Works

Git-ripper operates in five stages:

1. URL Parsing: Extracts repository owner, name, branch, and target folder path
2. Resume Check: Looks for existing download progress and validates already downloaded files
3. API Request: Uses GitHub's API to fetch the folder structure
4. Content Download: Retrieves each file individually while maintaining directory structure and saving progress
5. Local Storage or Archiving: Saves files to your specified output directory or creates an archive

The resume functionality uses checkpoint files stored in .git_ripper_checkpoints/ to track download progress, file integrity hashes, and metadata for each download session.

Configuration

Git-ripper works out of the box without configuration. For rate-limited GitHub API usage or private repositories, use the --gh-token option as described in the Authentication section.

Troubleshooting

Common Issues

Rate Limit Exceeded

Error: Request failed with status code 403

Solution: GitHub limits unauthenticated API requests. You can either:

1. Wait a few minutes and try again
2. Use the --gh-token option with a Personal Access Token to significantly increase your rate limit

Invalid URL Format

Error: Invalid GitHub URL format

Solution: Ensure your URL follows the pattern: https://github.com/owner/repo/tree/branch/folder

Folder Not Found

Error: Path not found in repository

Solution: Verify the folder path exists in the specified branch and repository.

Resume Issues

If you encounter problems with resume functionality:

# Clear all checkpoints and start fresh
git-ripper https://github.com/owner/repo/tree/branch/folder --force-restart

# Or disable resume entirely
git-ripper https://github.com/owner/repo/tree/branch/folder --no-resume

Corrupted Download

If files appear corrupted after resume:

# Force restart will re-download everything
git-ripper https://github.com/owner/repo/tree/branch/folder --force-restart

The resume feature automatically detects and re-downloads corrupted files, but --force-restart ensures a completely clean download.
