Project Summary
Flogger is a fluent logging API for Java. It supports a wide variety of features, and has many benefits over existing logging APIs.
Come for more self-documenting log statements:
logger.atInfo().withCause(exception).log("Log message with: %s", argument);
Stay for additional features that help you manage your logging better:
logger.atSevere()
.atMostEvery(30, SECONDS)
.log("Value: %s", lazy(() -> doExpensiveCalculation()));
