Improve virtualenv aware by searching subdirectories

[uoo723]

The common pattern of creating virtualenv is creating subdirectory.

$ virtualenv projectDIR/venv

So, I added code that searches that directory and assigns proper value for VIRTUAL_ENV.

The common way of using ide-python is to add the project directory you want to work with to your Atom project in the tree view. This way venv would be on the top level.
Could you elaborate on your use case why this isn't possible?

[uoo723]

In my case, I usually put the venv in root project.
So, It looks like this.

myproject
+-- venv
|     +-- bin
|     +-- include
|     +-- lib
+-- django
|     +-- django
|     |     +-- __init__.py
|     |     +-- settings.py
|     |     +-- urls.py
|     +-- app
|     |     +-- __init__.py
|     |     +-- apps.py
|     +-- manage.py
+-- .gitignore
+-- README.md
+-- requirements.txt

In this case, ide-python doesn't seem to aware venv.

@uoo723 Thanks for elaborating. I'm not familiar with virtual envs but I think this makes sense to add.
I'm not sure if it adds a lot to the startup time of the package but I guess it should be OK.

Thanks for the PR 🎉

Could you update the code to use asynchronous methods as much as possible, so ide-python won't block the UI.

[lgeiger]

Could you use the asynchronous method getEntries() because getEntriesSync() can block the UI if it takes too long?

Personally I'd wrap it in a Promise to be able to use it with async/await but you can also use native callbacks. What ever you prefer.

[uoo723]

I just updated.

[lgeiger]

Would prefer async here too.

[lgeiger]

Thanks for converting everything to async. 👍

I added one commit that ran prettier on the code and switched from var to let/const.

I think there's still room for simplification here and a small unit test for this functionality would be great but we can iterate on this in future PRs.

@uoo723 Are you interested in helping us maintain this package?

[uoo723]

I’d be happy to help you with this package.
