About:
Sad is a CLI tool designed for high-performance search and replace operations across codebases. It leverages SIMD instructions and parallel processing to deliver significantly faster results than traditional tools like sed. The tool supports regex matching and provides real-time previews of changes before execution.
Key Features:
  • SIMD-accelerated pattern matching for maximum speed
  • Real-time diff preview before applying changes
  • Parallel processing for multi-core performance
  • Familiar regex syntax with modern enhancements
Use Cases:
  • Refactoring large codebases with find-and-replace operations
  • Bulk renaming or updating of files in development projects
  • Automated code cleanup and migration tasks
Alternatives:
  • sed – Standard Unix tool, significantly slower on large datasets
  • ripgrep – Excellent search capabilities, but Sad specializes in search-and-replace workflows
