dataconf 0.1.0

Lightweight configuration with automatic dataclasses parsing (HOCON/JSON/YAML/PROPERTIES)

Dataconf

Getting started

Requires at least Python 3.8.

pip3 install --upgrade git+https://github.com/zifeo/dataconf.git
poetry add git+https://github.com/zifeo/dataconf.git

Examples

conf = """
str = test
str = ${HOSTNAME}
float = 2.2
list = [
    a
    b
]
nested {
    a = test
}
nestedList = [
    {
        a = test1
    }
]
duration = 2s
"""

@dataclass
class Nested:
    a: str

@dataclass
class Config:
    str: str
    float: float
    list: List[str]
    nested: Nested
    nestedList: List[Nested]
    duration: timedelta

import dataconf
print(dataconf.load(conf, Config))
# TestConf(test='pc.home', float=2.1, list=['a', 'b'], nested=Nested(a='test'), nestedList=[Nested(a='test1')], duration=datetime.timedelta(seconds=2))

conf = dataconf.loads('confs/test.hocon', Config)
conf = dataconf.loads('confs/test.json', Config)
conf = dataconf.loads('confs/test.yaml', Config)
conf = dataconf.loads('confs/test.properties', Config)

dataconf.dumps('confs/test.hocon', out='hocon')
dataconf.dumps('confs/test.json', out='json')
dataconf.dumps('confs/test.yaml', out='yaml')
dataconf.dumps('confs/test.properties', out='properties')

Follows same api as python JSON package (e.g. load, loads, dump, dumps). For full HOCON capabilities see here.

CI

dataconf -c confs/test.hocon -m tests.configs -d TestConf -o hocon
# dataconf.exceptions.TypeConfigException: expected type <class 'datetime.timedelta'> at .duration, got <class 'int'>
