repren

Repren is a “rename anything” command-line tool that performs regex-based search and replace across file contents while also renaming or moving files and directories according to patterns. It’s meant for sweeping refactors: change a class or package name everywhere and update filenames to match in one pass. The design favors explicitness and safety, providing dry-run output so you can preview exactly what will change before executing it. It handles recursive directory walks, lets you filter which files to touch, and supports multiple patterns in a single run to keep transformations consistent. Because it’s script-friendly, it slots well into project maintenance, codebase migrations, or release engineering tasks. The goal is to give you a reliable, repeatable alternative to ad-hoc shell loops when large-scale text and filename changes are needed.
