Severity is level of log message importance. It uniquely determines which messages to print.

Log a message using the given logger at a given priority.

Allow graceful shutdown. Release all opened fileshandlersetc.

Returns the logger for the given name. If no logger with that name exists, creates new loggers and any necessary parent loggers, with no connected handlers.

Returns the root logger.

The name of the root logger, which is always defined and present on the system.

Add handler to Logger. Returns a new Logger.

Remove a handler from the Logger. Handlers are removed in the reverse order they were added, so the following property holds for any LogHandler h:

removeHandler . addHandler h = id

If no handlers are associated with the Logger, it is returned unchanged.

The root logger's default handler that writes every message to stderr can be removed by using this function before any handlers have been added to the root logger:

updateGlobalLogger rootLoggerName removeHandler

Set the 'Logger'\'s list of handlers to the list supplied. All existing handlers are removed first.

Returns the "level" of the logger. Items beneath this level will be ignored.

Sets the "level" of the Logger. Returns a new Logger object with the new level.

Clears the "level" of the Logger. It will now inherit the level of | its parent.

Set severities for given logger. By default parent's severities are used.

Set or clear severities.

Updates the global record for the given logger to take into account any changes you may have made.

Helps you make changes on the given logger. Takes a function that makes changes and writes those changes back to the global database. Here's an example from above ("s" is a LogHandler):

updateGlobalLogger "MyApp.BuggyComponent"
                   (setLevel DEBUG . setHandlers [s])

Sets file prefix to LogInternalState.

Retrieves content of log file(s) given path (w/o _lcFilePrefix, as specified in your config). Example: there's component.log in config, but this function will return [component.log.122, component.log.123] if you want to. Content is file lines newest first.

FYI: this function is implemented to avoid the following problem: log-warper holds open handles to files, so trying to open log file for read would result in IOException.
