Fault if env vars are not found #249
Description
I get:
flutter: Traceback (most recent call last):
File "/usr/lib/linux-assistant/additional/python//get_applications.py", line 79, in <module>
dataDirs = os.getenv("XDG_DATA_DIRS").split(":")
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'split'
There are a number of places where os.getenv() is used without defaults and result in exceptions when the code runs.
Two such places are get_applications.py#79 and #81. There is a helper in jessentials.py, "get_environment_variable()" but it isn't used.
In addition, on line #81, just assuming "HOME" is an env variable isn't all that useful, instead, perhaps it would be better to defer to HOME if it exists but default to something like:
from pathlib import Path
str=str(Path('~').expanduser())
81: if jfolders.does_folder_exist(os.getenv("HOME",str) + "/.local/share/applications"):
