Image Handling

The tool automatically downloads and validates all images found in issues:

Supported Image Formats

• PNG, JPEG, GIF, WebP
• BMP, ICO, SVG

Image Features

• Automatic Download: Images in both markdown (![alt](url)) and HTML (<img src>) syntax are detected
• Magic Bytes Validation: Images are validated by content, not just file extension
• GitHub Authentication: Uses your GitHub token for private repository images
• Redirect Handling: Properly follows S3 signed URLs and other redirects
• Error Handling: Gracefully handles missing/expired URLs with warnings
• Local References: Markdown is updated to reference downloaded images

Output Structure

issue-123.md              # Issue body and comments in markdown
issue-123-images/         # Directory with downloaded images
  image-1.png
  image-2.jpg
issue-123.json            # Optional JSON export (with --format json)

Authentication

The tool supports multiple authentication methods for accessing private issues:

1. GitHub CLI (Recommended)

If you have GitHub CLI installed and authenticated, the script will automatically use your credentials:

# Authenticate with GitHub CLI (one-time setup)
gh auth login

# Script automatically detects and uses gh CLI authentication
gh-load-issue owner/repo#123  # Works with private issues!

2. Environment Variable

Set the GITHUB_TOKEN environment variable:

export GITHUB_TOKEN=ghp_your_token_here
gh-load-issue owner/repo#123

3. Command Line Token

Pass the token directly with --token:

gh-load-issue owner/repo#123 --token ghp_your_token_here

Authentication Priority

The script uses this fallback chain:

1. --token command line argument (highest priority)
2. GITHUB_TOKEN environment variable
3. GitHub CLI authentication (if gh is installed and authenticated)
4. No authentication (public issues only)

Examples

# Basic usage - download a public issue
gh-load-issue https://github.com/torvalds/linux/issues/123

# Use short format
gh-load-issue torvalds/linux#123

# Download private issue (using GitHub CLI auth)
gh-load-issue myorg/private-repo#456

# Save to specific location
gh-load-issue owner/repo#789 --output ./issues/issue-789.md

# Export as JSON for programmatic use
gh-load-issue owner/repo#123 --format json

# Verbose mode for debugging
gh-load-issue owner/repo#123 --verbose

# Skip image download (faster, text only)
gh-load-issue owner/repo#123 --no-download-images

# Use explicit token
gh-load-issue owner/repo#123 --token ghp_your_token_here
