Utilities for editing tox.ini
Decision gist · record as of 2026-08-14
Yes, if you need to parse or modify tox.ini files programmatically. The package is actively maintained, has no dependencies, installs easily, carries a permissive MIT license, and requires only Python 3.10+. It is well-suited for build tools, CI scripts, and configuration management. Not necessary if you only read tox.ini manually or use tox itself without programmatic modification.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
codemod-tox is a utility library for programmatically reading and modifying tox.ini configuration files. It provides parsers for tox environment lists, individual environment definitions, and conditional dependency specifications, allowing you to construct, expand, and transform these configurations as Python objects rather than manipulating raw strings.
The library is designed for tools that need to analyze or rewrite tox configurations—such as linters, migration scripts, or test infrastructure generators. It has no runtime dependencies and installs with low friction. It requires Python 3.10 or later and follows semantic versioning with a commitment to rename on major version changes.
Use it for
- Automatically expand or filter tox environment matrices in CI/CD pipeline configuration scripts
- Build linting or validation tools that need to parse and understand tox.ini structure
- Generate or modify tox configurations programmatically in test infrastructure generators
- Migrate or refactor tox configurations across multiple projects using codemod-style transformations
- Analyze tox environment dependencies to detect conflicts or redundancies
