Usage​

Run this recipe

In order to run Python recipes, you will need to use the Moderne CLI.

This recipe calls into other OpenRewrite packages as it runs, and the CLI needs every one of them in its marketplace. Once the CLI is installed, install all of the following:

RELEASE resolves to the newest release and LATEST to the newest build of any kind, including snapshots. Either one lets mod config recipes upgrade pull in later versions without editing this command; a pinned version stays where you put it.

mod config recipes pip install openrewrite-migrate-python
mod config recipes jar install org.openrewrite.recipe:rewrite-migrate-python:RELEASE
mod config recipes jar install org.openrewrite:rewrite-python:RELEASE
