viaenv - Configuration via Environment for Python
viaenv uses variable annotation
to populate values from environment variables.
Example
from datetime import timedelta
from viaenv import populate_from_env
class config:
port: int = 8080
log_file: str = '/var/log/server.log'
timeout: timedelta = timedelta(milliseconds=100)
populate_from_env(
config, prefix='SRV',
# If you don't pass env, populate_from_env will use os.environ
env={'SRV_PORT': '9000', 'SRV_TIMEOUT': '300ms'})
print(config.port) # 9000
print(cfg.timeout == timedelta(milliseconds=300) # True
Supported Types
bool:y,yes,t,true,on,1->True,n,no,f,false,off,0->Falsedate:2019-05-18datetime:2019-05-18T13:43:12dict:{"x": 1, "y": 2}(JSON format)float:1.3,1e7int:12,0x12,0o12,0b12list:[1, 2, 3](JSON format)str: Anything goestime:13:43:12timedelta:10us,20ms,30s,17m,2h,7d,1h20m
You can add your types by calling register_type_parser(typ, parser) where
typ is a type (e.g. float) and parser is a one argument function that
will get the value as a string.
