✨ Features Implemented¶

10 Forking Strategies¶

Strategy	Description	Primary Use Case
full	Complete clone with full history	Development, long-term work
shallow	Limited commit history (default: 1)	Quick reviews, CI/CD
sparse	Specific directories only	Monorepos, focused work
toplevel	Root-level files only	Quick overview, README review
structure	Directory tree (empty files)	Understanding organization
filetype	Files by extension	Language-specific analysis
analysis	Shallow + sparse combined	Fast security audits
mirror	Bare repository clone	Backups, archival
bundle	Single-file git bundle	Offline work, transfers
metadata	Repository info only (no clone)	Pre-assessment, research

Advanced Capabilities¶

✅ GitHub CLI Integration: Automatic fork creation with duplicate detection
✅ Intelligent Filtering: By file type, directory path, and custom patterns
✅ Input Validation: Prevents common errors (invalid paths, extensions)
✅ Error Handling: Comprehensive error checking with helpful messages
✅ Cleanup on Failure: Automatic cleanup of temporary directories
✅ Dry Run Mode: Preview operations without making changes
✅ Verbose Logging: Debug mode for troubleshooting
✅ Cross-Platform: macOS, Linux, and WSL support
✅ Target Directory Control: Custom output locations

GitHub CLI (gh): Fork creation and API access
jq: JSON parsing for metadata
Standard Unix tools: find, grep, sed, awk, tree

Design Patterns¶

Strategy Pattern: Different cloning strategies with common interface
Template Method: Common execution flow with strategy-specific implementations
Error Handling: Comprehensive checks with early exit on critical errors
Resource Management: Cleanup trap ensures temporary files are removed

Bundle strategy reliability
Added proper error handling
Automatic cleanup of temporary clones
Better error messages on failure

Checks for target directory conflicts
Cleanup mechanism
Automatic cleanup on script exit
Cleanup on interrupt (Ctrl+C)
Cleanup on errors
Better error messages
More descriptive error messages
Helpful suggestions for common issues
