class (MonadLogger m, MonadIO m) => MonadLoggerIO (m :: Type -> Type) where Source #

An extension of MonadLogger for the common case where the logging action is a simple IO action. The advantage of using this typeclass is that the logging function itself can be extracted as a first-class value, which can make it easier to manipulate monad transformer stacks, as an example.

runChanLoggingT :: MonadIO m => Chan LogLine -> LoggingT m a -> m a Source #

Run a block using a MonadLogger instance which writes tuples to an unbounded channel.

Since: 0.3.17

Run a block using a MonadLogger instance which appends to the specified file.

Since: 0.3.22

unChanLoggingT :: (MonadLogger m, MonadIO m) => Chan LogLine -> m void Source #

Read logging tuples from an unbounded channel and log them into a MonadLoggerIO monad, forever.

For use in a dedicated thread with a channel fed by runChanLoggingT.

Since: 0.3.17

withChannelLogger Source #

Arguments

:: forall (m :: Type -> Type) a. (MonadBaseControl IO m, MonadIO m)
=> Int	Number of messages to keep
-> LoggingT m a
-> LoggingT m a

Within the LoggingT monad, capture all log messages to a bounded channel of the indicated size, and only actually log them if there is an exception.

Since: 0.3.2

filterLogger :: forall (m :: Type -> Type) a. (LogSource -> LogLevel -> Bool) -> LoggingT m a -> LoggingT m a Source #

Only log messages passing the given predicate function.

This can be a convenient way, for example, to ignore debug level messages.
