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.
