Codemodder

This is the Java version of the Codemodder Framework, which builds on traditional codemod frameworks by providing codemods with additional context and services. Codemodder plugins inject codemods with the context and services they need to perform complex transforms.

Pluggability and the complex transforms they enable distinguish codemodder codemods from traditional codemods.

Developing

Follow these instructions if you intend to modify and build this project from source.

First Time Set Up

1. Install JDK 17 for building this project. We recommend Eclipse Adoptium

2. Install Semgrep CLI. See here for instructions. It can usually be done via pip:

   pip install semgrep

If your python library paths contain your home directory as a root folder (i.e. due to the use of the $HOME environment variable), you may need to manually set up your PYTHONPATH for tests:

PYTHONPATH=$HOME/<subpath-to-python-libs-folder> ./gradlew check

You can check your python paths with:

python -m site

Building

./gradlew assemble

Running Tests

./gradlew check

Run the Core Codemods

./gradlew :core-codemods:run --args='--output /path/to/my.codetf --dry-run /path/to/project/'
