[Core Package] A simple high-level framework for research

Cinnamon (Core Package)

Cinnamon is a simple framework for general-purpose configuration and code logic de-coupling. It was developed to offer two main functionalities:

De-coupling a code logic from its regulating parameters

Re-use of code logic without effort

Background

Consider a code logic that has to load some data.

   class DataLoader:

      def load(...):
          data = read_from_file(folder_name=self.folder_name)
          return data

The data loader reads from a file located according to self.folder_name's value.

If self.folder_name has multiple values, we can use the same code logic to load data from different folders.

Hypothetically, we would define multiple data loaders:

   data_loader_1 = DataLoader(folder_name='*folder_name1*')
   data_loader_2 = DataLoader(folder_name='*folder_name2*')
   ...

Now, if the data loader code block is used in a project, we require some code modularity to avoid defining several versions of the same script. One common solution is to rely on configuration files (e.g., JSON file).

   {
      'data_loader' : {
         'folder_name': '*folder_name1*'
      }
   }

The main script is modified to load our configuration file so that each code logic is properly initialized.

Cinnamon

Well, cinnamon keeps this <configuration, code logic> dichotomy where a configuration is written in plain Python code!

   class DataLoaderConfig(Configuration):

      @classmethod
      def get_default(cls):
         config = super().get_default()

         config.add(name='folder_name',
                    type_hint=str,
                    is_required=True,
                    variants=['*folder_name1*', '*folder_name2*', ...],
                    description="Base folder name from which to look for data files.")
         return config

Cinnamon allows high-level configuration definition (constraints, type-checking, description, variants, etc...)

To quickly load any instance of our data loader code logic, we

register the configuration via a registration key

      key = RegistrationKey(name='data_loader', namespace='showcase')
      Registry.add_configuration_variants_from_key(config_class=DataLoaderConfig,
                                 key=key)

bind the configuration to its code logic: DataLoaderConfig --> DataLoader

   Registry.bind(config_class=DataLoaderConfig,
                 component_class=DataLoader,
                 key=key)

build the DataLoader code logic with a specific configuration instance via the used registration key

   variant_key = RegistrationKey(name='data_loader', tags={'folder_name=*folder_name1*'}, namespace='showcase')
   data_loader = Registry.build_component(key=variant_key)

That's it! This is all of you need to use cinnamon.

Features

General-purpose cinnamon is meant to simplify your code organization for better re-use.

Simple cinnamon is a small library that acts as a high-level wrapper for your projects.

Modular cinnamon is shipped in several small packages to meet different requirements.

Community-based the Component and Configuration you define can be imported from/exported to other users and project!

Flexible cinnamon imposes minimal APIs for a quick learning curve.

You are still free to code as you like!

Install

pip

  pip install cinnamon-core

git

  git clone https://github.com/federicoruggeri/cinnamon_core
