e-volv-openfeature

OpenFeature provider for e-volv Launch flags, on top of the e-volv-logs Python SDK.

Evaluation underneath stays synchronous and never raises (the e-volv Launch SDK contract); only initialize waits — and only because OpenFeature's provider handshake asked it to.

Usage

from openfeature import api
from openfeature.evaluation_context import EvaluationContext

from evolve_logs import LogsClient, FlagsOptions
from evolve_openfeature import EvolveProvider

logs = LogsClient(
    key="evk_…", url="https://api.e-volv.io/api/public/v1/logs", flags=FlagsOptions()
)
api.set_provider(EvolveProvider(logs.flags))

client = api.get_client()
details = client.get_boolean_details(
    "checkout.new",
    False,
    EvaluationContext(targeting_key="u_1", attributes={"plan": "pro"}),
)
details.value, details.variant, details.flag_metadata["evolveReason"]

Reason and error mapping

The native e-volv reason is always preserved as flag_metadata["evolveReason"].
