Allow environment variables in default values #46

Open roman opened 6 years ago

roman commented 6 years ago

Is not uncommon to require some default configuration values to expand from environment variables (e.g. $HOME)

Implementation Suggestions:

Add a new function resolveDefaultEnv that makes use of the environment variables
Interpolates the default values; the API detects that a ${VAL} is being used in value and it interpolates it with the correct value
