Build out user dir #31

inverse · 2021-07-06T19:57:40Z

Prepare for packaging up as an application by moving user data out of the project repository to the user home directories.

This is a significant change.

Partial work for #29

All path based information is encapsulated in this class

We should probably store this class in another file. With that being said, we should really organize the layout of the project.. Everything is kinda all scattered all across right now

I would advise perhaps doing that in another PR. Doing things incrementally and in small commits is easier. Especially to revert if things go south.

Nice! Thank you for your contribution my friend!

I will have a more thorough review in the next few days and merge

Nice change! We should really convert camel case to snake case over time

snake case is the python way. If you're happy with something we could use black?

We can configure it as a pre-commit hook even :)

Although not sure how it handles variable naming come to think about it 🤔

pylint will help enforce it ;)

Yeap. We should really start leveraging pylint and mypy

We can also use the exist_ok kwarg and set that to True so we don't need to check the conditional

Won't that change the semantics of the function?

As in we return true/false if the directory exists?

LGTM so far.

Super important this is done here otherwise we init PATHS before setting the env var to control which one gets init

We should probably refactor this code to use makedirs()

create_folder_if_needed calls that under the hood.

We should migrate to pipenv, so much easier with [dev-packages[ and piplock...

We could do - but lets leave that to another PR ;)

There is also https://python-poetry.org/

I've not used but looks quite nice.

Could prob have this defined as a callback and passed into the caller.

But that's for another PR
