Overview

Package plugin maps a Go plugin interface to a technical command line interface. Thereby, it allows to embed plugins and their provided functionality into the library. It is the basis for adapter implementations for accessmethods, downloaders, uploaders, blob handlers, actions, value mergers and label merge specifications. Those adapters can be found in the subpackage "plugin" of their dedicated functional area packages (e.g. pkg/contexts/ocm/accessmethods/plugin).
