Verbose Logging

A family of wrappers of selected futile.logger::futile.logger functions that control the logging mechanism in crmPack. The crmPack uses futile.logger::futile.logger package for the logging purposes. All the messages logged in crmPack are logged into crmPack logger at the futile.logger::TRACE level. Hence, enabling verbose logging means that the logging threshold will be set to futile.logger::TRACE for the crmPack logger, and disabling verbose logging means that it will be set to futile.logger::FATAL.

Usage

enable_logging()

disable_logging()

is_logging_enabled()

log_trace(msg, ..., capture = FALSE)

Arguments

msg

The message to log

...

Optional arguments to populate the format string

capture

Capture print output of variables instead of interpolate

Functions

• enable_logging(): A simple wrapper of futile.logger::flog.threshold() that enables crmPack verbose logging by setting logging threshold to futile.logger::TRACE for crmPack logger.

• disable_logging(): A simple wrapper of futile.logger::flog.threshold() that disables crmPack verbose logging by setting logging threshold to futile.logger::FATAL for crmPack logger.

• is_logging_enabled(): A simple wrapper of futile.logger::flog.logger() that checks whether current threshold level for crmPack logger is verbose, which is futile.logger::TRACE. It returns TRUE if the current logging level is verbose, FALSE otherwise.

• log_trace(): A simple wrapper of futile.logger::flog.trace() that prints a log message in the crmPack logger.
