How to create an alba sub-module

Let's say a new high pressure lab has been installed at ALBA which requires specific software. The goal is the user can type:

import alba.hplab

... to have access to ALBA's specific high pressure lab software.

Preparation

In the future there might be a cookie cutter for this. For now we have to bootstrap the project by hand:

1. create a directory called hplab and enter it.
2. create a directory called alba
3. create a alba/__init__.py file with a single line:

__path__ = __import__('pkgutil').extend_path(__path__, __name__)

It is crucial that the alba/__init__.py has this precise contents and no more.

4. create a setup.py has usual. Here is a minimal version:

# setup.py

from setuptools import setup, find_packages

setup(
    name="alba-hplab",
    author="ALBA controls team",
    author_email="[e-mail]",
    packages=find_packages(),
    description="ALBA controls HP Lab software",
    version="0.0.1"
)

5. create a alba/hplab directory. This is where you should put the specific code for ALBA's HP lab.

By now you should have a structure like this

hplab/
├── alba
│   ├── hplab
│   │   └── __init__.py
│   └── __init__.py
└── setup.py

That's it! If you publish your package on pypi you will be able to install your software anywere with:

pip install alba-hplab
