codemodder 0.82.0

A pluggable framework for building codemods in Python

codemodder-python

This is the Python version of the Codemodder Framework.

Codemodder is sponsored by pixee.ai.

Development Status

As of v0.80.0 the codemod API is relatively stable. However, backwards compatibility between releases will not be guaranteed until version 1.0.0.

See CHANGELOG.md for detailed release notes.

Installation

The codemodder package is available on PyPI. To install, run:

$ pip install codemodder

To install the package from source, use pip:

$ pip install /path/to/codemodder-python

Running Locally

The codemodder package provides an executable called codemodder. This should be available on your path by default after installation.

For basic usage, run the codemodder command with a target directory path:

$ codemodder /path/to/my-project

Note that by default codemodder will make changes to files in your target directory. To run codemodder without making updates on disk, use the --dry-run flag:

$ codemodder --dry-run /path/to/my-project

To list all available codemods (including any that are registered with installed plugins), use the --list option:

$ codemodder --list

For a full list of options, use the --help flag:

$ codemodder --help

Architecture

Codemods are composed of the following key components:

• Detector
• Transformer(s)
• Metadata

Custom Codemods

The Python codemodder supports a plugin infrastructure for custom codemods. For users interested in developing a custom codemod plugin, we recommend starting with the Cookiecutter template.
