scopedlog
A library for scoped logging on top of structlog (or similar sinks), inspired by the idea of an apparently defunct lithoxyl. Note that I (kshpytsya) have deliberatly not looked into actual lithoxyl's implementation to keep a fresh mind.
Install:
pip install 'scopedlog[structlog]'
Here is an example:
import contextlib import structlog
import structlog.stdlib
import structlog.dev
import structlog.processors
import scopedlog
import scopedlog.sink_structlog
import scopedlog.idgen_seq
structlog.configure(processors=[
structlog.stdlib.add_log_level,
structlog.processors.ExceptionPrettyPrinter(),
structlog.dev.ConsoleRenderer()
])
slog = scopedlog.ScopedLog(
sink=scopedlog.sink_structlog.StructlogSink(structlog.get_logger()),
id_gen=scopedlog.idgen_seq.GlobalSeqScopeIdGenenerator()
)
with contextlib.suppress(RuntimeError):
with slog.info("scope1", k1=1) as sl:
sl.debug("state1", k2=2, k3=3)
sl.info("state1", k4=4)
sl.warn("state1", k5=5)
raise RuntimeError("bad one")
with contextlib.suppress(RuntimeError):
with slog.debug("scope2", k1=1) as sl:
sl.debug("state1", k2=2, k3=3)
sl.info("state1", k4=4)
sl.warn("state1", k5=5)
raise RuntimeError("bad too ;)")
with slog.debug("scope3") as sl:
sl.fail()
with slog.debug("scope4") as sl:
sl.exit_kw["k1"] = 1And expected output:
See tests for more examples.
