PocketCoffea is a slim configuration framework for CMS NanoAOD analysess based on Coffea.

The goal of the framework is to define an HEP analysis in a declarative way where possible (with a well defined configuration files), and with python code where customization is needed (by subclassing the base PocketCoffea processor).

PocketCoffea defines a customizable structure to process NanoAOD events and define weights, categories, histograms. This is done thans to a BaseProcessor class which defines a workflow of operations to go from Raw NanoAOD to histograms. The user can customize the process from the confguration file or by redefining well-defined steps in the workflow.
