opg-data

This repository contains shared packages and infrastructure code used by various integration points into the case management system used by The Office of The Public Guardian, Sirius.

Creating shared packages

Preparing your code

The main thing to get right is the folder structure.

Create a new folder in the shared_code directory. This will hold all of the code and settings for your package. The name doesn't matter here, just call it something sensible.

To create a project locally, create the following file structure:

[[package_name_holding_folder]]
└── [[package_name]]
    └── __init__.py

Creating the package files

You will now create a handful of files to package up this project and prepare it for distribution. Create the new files listed below and place them in the project’s root directory - you will add content to them in the following steps.

[[package_name_holding_folder]]
├── LICENSE
├── README.md
├── [[package_name]]
│   └── __init__.py
├── setup.py
└── tests

Creating setup.py

setup.py is the build script for setuptools. It tells setuptools about your package (such as the name and version) as well as which code files to include.

Open setup.py and enter the following content.

import setuptools

with open("README.md", "r") as fh:
    long_description = fh.read()

setuptools.setup(
    name="[[package_name]]",
    version="0.0.1",
    author="OPG",
    author_email="example@digital.justice.gov.uk",
    description="Sirius Service",
    long_description=long_description,
    long_description_content_type="text/markdown",
    url="https://github.com/ministryofjustice/opg-data",
    packages=setuptools.find_namespace_packages(include=['[[package_name]]']),
    classifiers=[
        "Programming Language :: Python :: 3",
        "License :: OSI Approved :: MIT License",
        "Operating System :: OS Independent",
    ],
    python_requires=">=3.7",
)

This is a very simple version of setup.py, you can make this much more complicated if you need to. This example version uses find_namespace_packages to ensure we just build only the project files and don't include things like tests and other unneccessary files.
