e2e.common 0.1.4

Core modelling framework components for the e2e package ecosystem

e2e.common

Common code for the Python E2E package ecosystem.

This package complies with PEP-484, PEP-526, and PEP-561 for distribution of type information.

Core Modules

e2e.common.modelling: Object-based Modelling Framework

A modelling framework is provided by modelling.NamedParentable, using metaclass construction to stitch instance parents together in a class-based modelling approach.

For examples on how this is used, please see e2e.pom or e2e.api, as both packages use this modelling approach as of their 1.x releases.

For the 1.0 release, only NamedParentable is provided and requires users to explicitly name instances of models for best-possible human-friendly logging.

For the 2.0 release, options will exist for auto-naming and omission of the naming requirement. Stay tuned.

e2e.common.utils: General Utility Functions

Generalised utility functions reside in here. To reside here, they must be used by more than one e2e.* package.

Compatibility

Python 3.6+ is required due to various metaclass and type-hinting functinality used. Backporting to 3.5 is possible with more significant effort and potential loss of certain features and type-hinting; please file an issue if you require this, explaining the motivation if possible.

Other than that, this is a pure Python package and should be compatible with any OS and platform which Python runs on.

Contributing & Development

I haven’t put much thought into others contributing here. Please reach out if there are changes you’d like to make!

The Makefile (which has only been tested on Linux distros) holds my development process:

• make format: to run black and isort formatters

• make lint: to run mypy (type check), pylint, and flake8

• make test: to run unit tests

• make tox: to run unit tests on multiple Python versions

• make wheel and make sdist: to build such package archives

Otherwise, this is a fairly standard package repo using virtual environments and setup.py.

Note that the build environment (no unnecessary packages) is different from the development environment (contains all packages for development).
