Example

logger := zapctxd.New(zapctxd.Config{
    Level:     zap.WarnLevel,
    DevMode:   true,
    StripTime: true,
})

ctx := ctxd.AddFields(context.Background(),
    "foo", "bar",
)

logger.Info(ctx, "not logged due to WARN level config")

logger.Error(ctx, "something failed",
    "baz", 1,
    "quux", 2.2,
)

logger.Important(ctx, "logged because is important")
logger.Info(ctxd.WithDebug(ctx), "logged because of forced DEBUG mode")

logger.SetLevelEnabler(zapcore.DebugLevel)
logger.Info(ctx, "logged because logger level was changed to DEBUG")

// Output:
// <stripped>	ERROR	zapctxd/example_test.go:26	something failed	{"baz": 1, "quux": 2.2, "foo": "bar"}
// <stripped>	INFO	zapctxd/example_test.go:31	logged because is important	{"foo": "bar"}
// <stripped>	INFO	zapctxd/example_test.go:32	logged because of forced DEBUG mode	{"foo": "bar"}
// <stripped>	INFO	zapctxd/example_test.go:35	logged because logger level was changed to DEBUG	{"foo": "bar"}
