About:
fastmod is a fast, partial replacement for codemod. It is a tool designed for programmers to perform large-scale text replacements across many files. It provides a user-friendly interactive mode to review and accept changes, making it ideal for refactoring codebases.
Key Features:
  • High performance written in Rust for speed
  • Interactive review mode to accept or reject changes
  • Supports regular expressions and file filtering
  • Preserves code formatting during replacements
Use Cases:
  • Refactoring variable or function names across a large codebase
  • Bulk updating configuration files or API endpoints
  • Applying project-wide coding standard changes
Alternatives:
  • codemod – The original Python-based tool; fastmod is a faster, Rust-based successor with a more streamlined interactive interface.
  • sed – A standard Unix utility for text transformation; fastmod offers safer, interactive previews and better handling of code structures.
