dict-envy
dict-like grouping of environment variables
Imagine you have this:
COUNTRIES_GB_NAME="United Kingdom"
COUNTRIES_GB_TLD=.uk
COUNTRIES_HK_NAME=China
COUNTRIES_HK_TLD=.cn
and with a simple call you can have all of this:
>>> import os
>>> import dictenvy
>>> import pprint
>>> env = dictenvy.dictate(os.environ, depth=2)
>>> pprint.pprint(env)
{'countries': {'gb': {'name': 'United Kingdom', 'tld': '.uk'},
'hk': {'name': 'China', 'tld': '.cn'}}}depth is how you regulate the depth of the returned dictionary.
Couple gotchas
#1
Sometimes you may encounter the following situation:
TERM_PROGRAM=Apple_Terminal
TERM=xterm-256color
In which case, the return value would still be a dict, but TERM value would have an empty key like so:
>>> import dictenvy
>>> import pprint
>>> env = dictenvy.dictate({'TERM': 'xterm-256color', 'TERM_PROGRAM': 'Apple_Terminal'}, depth=1))
>>> pprint.pprint(env)
{'term': {'': 'xterm-256color', 'program': 'Apple_Terminal'}}#2
Variables that start with an underscore will be left alone.
