Environment collector plugins


Environment collectors allow for dynamically modifying environments or adding environments beyond those defined in config. Users can override default values provided by each environment.

EnvironmentCollectorInterface

Example usage:

from hatch.env.collectors.plugin.interface import EnvironmentCollectorInterface


class SpecialEnvironmentCollector(EnvironmentCollectorInterface):
    PLUGIN_NAME = 'special'
    ...
from hatchling.plugin import hookimpl

from .plugin import SpecialEnvironmentCollector


@hookimpl
def hatch_register_environment_collector():
    return SpecialEnvironmentCollector
