To benefit from type hinting, make sure =my.config= is in your package search path.

* Modifying/adding modules
The easiest is just to run HPI via [[file:SETUP.org::#use-without-installing][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 [[https://packaging.python.org/guides/packaging-namespace-packages]["namespace packages"]] for more info.
