Running tests
I'm using tox to run test/lint. You can check out Github Actions config
and /fz0x1/HPI/src/commit/c410daa4844e9a70be4eefe10575c3661bc456e8/scripts/ci/run for the up to date info on the specifics.
IDE setup
To benefit from type hinting, make sure my.config is in your package search path.
In runtime, my.config is imported from the user config directory dynamically.
However, Pycharm/Emacs/whatever you use won't be able to figure that out, so you'd need to adjust your IDE configuration.
- Pycharm: basically, follow the instructions here
i.e. create a new interpreter configuration (e.g. name it "Python 3.7 (for HPI)"), and add
~/.config/my.
Linting
You should be able to use /fz0x1/HPI/src/commit/c410daa4844e9a70be4eefe10575c3661bc456e8/lint script to run mypy checks.
/fz0x1/HPI/src/commit/c410daa4844e9a70be4eefe10575c3661bc456e8/mypy.ini points at ~/.config/my by default.
Modifying/adding modules
The easiest is just to run HPI via with_my wrapper or with an editable PIP install. That way your changes will be reflected immediately, and you will be able to quickly iterate/fix bugs/add new methods.
The "proper way" (unless you want to contribute to the upstream) is to create a separate hierarchy and add your module to PYTHONPATH.
For example, if you want to add an awesomedatasource, it could be:
custom_module
└── my
└──awesomedatasource.py
You can use all existing HPI modules in awesomedatasource.py, for example, my.config, or everything from my.core.
But also, you can use all the previously defined HPI modules too. This could be useful to shadow/override existing HPI module:
custom_reddit_overlay
└── my
└──reddit.py
Now if you add my_reddit_overlay in the front of PYTHONPATH, all the downstream scripts using my.reddit will load it from custom_reddit_overlay instead.
This could be useful to monkey patch some behaviours, or dynamically add some extra data sources – anything that comes to your mind.
I'll put up a better guide on this, in the meantime see "namespace packages" for more info.
