lgr (version 0.3.4)

suspend_logging: Suspend All Logging

Description

Completely disable logging for all loggers. This is for example useful for automated test code. suspend_logging() globally disables all logging with lgr until unsuspend_logging() is invoked, while without_logging() and with_logging() temporarily disable/enable logging.

Usage

suspend_logging()
unsuspend_logging()
without_logging(code)
with_logging(code)

Arguments

code

Any R code

Value

suspend_logging() and unsuspend_logging() return NULL (invisibly), without_logging() and with_logging() returns whatever code returns.

Examples

# NOT RUN {
lg <- get_logger("test")

# temporarily disable logging
lg$fatal("foo")
without_logging({
  lg$info("everything in this codeblock will be suppressed")
  lg$fatal("bar")
})

# globally disable logging
suspend_logging()
lg$fatal("bar")
with_logging(lg$fatal("foo"))  # log anyways

# globally enable logging again
unsuspend_logging()
lg$fatal("foo")
# }
