Codemod is a Python tool and library from Facebook for assisting large-scale codebase refactors that are partially automated but need human oversight. It interactively shows diffs for regex-based replacements across many files, letting users accept, reject, or edit each change.
Use cases
- interactively refactor a large codebase with regex replacements
- review and approve each automated code change via a diff
- deprecate an API or tag across hundreds of files
- split a bulk code-editing task across a team with start/end offsets
- count occurrences of a pattern before refactoring
- edit matched lines in my editor during a bulk rename
When to choose
- you need human review on each automated replacement across many files
- you want a lightweight Python CLI without learning a full codemod framework
- you need to pause, resume, or divide refactoring work by file position
When to avoid
- you need AST-aware, language-specific transformations (use jscodeshift or a language codemod framework)
- you want fully automated, unattended bulk edits
- you need an actively maintained tool (the repo is archived)
