class ( MonadLogger m, MonadIO m) => MonadLoggerIO m 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.

liftLoc :: Loc -> Q Exp Source #

Lift a location into an Exp.

Since: 0.3.1

logDebugS :: Q Exp Source #

Generates a function that takes a LogSource and Text and logs a LevelDebug message. Usage:

$logDebugS "SomeSource" "This is a debug log message"

logOtherS :: Q Exp Source #

Generates a function that takes a LogSource , a level name and a Text and logs a LevelOther message. Usage:

$logOtherS "SomeSource" "My new level" "This is a log message"

runWriterLoggingT :: Functor m => WriterLoggingT m a -> m (a, [ LogLine ]) Source #

Run a block using a MonadLogger instance. Return a value and logs in a list | @since 0.3.28

execWriterLoggingT :: Functor m => WriterLoggingT m a -> m [ LogLine ] Source #

Run a block using a MonadLogger instance. Return logs in a list | @since 0.3.28

defaultOutput :: Handle -> Loc -> LogSource -> LogLevel -> LogStr -> IO () Source #

A default implementation of monadLoggerLog that accepts a file handle as the first argument.

This is used in the definition of runStdoutLoggingT :

runStdoutLoggingT :: MonadIO m => LoggingT m a -> m a
runStdoutLoggingT action =
    runLoggingT action (defaultOutput stdout)

Since: 0.3.36

runFileLoggingT :: MonadBaseControl IO m => FilePath -> LoggingT m a -> m a Source #

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

Since: 0.3.22

runStderrLoggingT :: MonadIO m => LoggingT m a -> m a Source #

Run a block using a MonadLogger instance which prints to stderr.

Since: 0.2.2

runStdoutLoggingT :: MonadIO m => LoggingT m a -> m a Source #

Run a block using a MonadLogger instance which prints to stdout.

Since: 0.2.2

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.

The tuples can be extracted (ie. in another thread) with unChanLoggingT or a custom extraction funtion, and written to a destination.

Since: 0.3.17

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

:: ( 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 :: ( 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.

Since: 0.3.13

mapLoggingT :: (m a -> n b) -> LoggingT m a -> LoggingT n b Source #

Map the unwrapped computation using the given function.

Since: 0.3.29

mapNoLoggingT :: (m a -> n b) -> NoLoggingT m a -> NoLoggingT n b Source #

Map the unwrapped computation using the given function.

Since: 0.3.29

defaultLoc :: Loc Source #

dummy location, used with logWithoutLoc

Since: 0.3.23

logDebugCS :: MonadLogger m => CallStack -> Text -> m () Source #

Logs a message with location given by CallStack . See CallStack for more convenient functions for CallStack based logging.

Since: 0.3.19

logDebug :: ( HasCallStack , MonadLogger m) => Text -> m () Source #

Logs a message with the location provided by an implicit CallStack .

Since: 0.3.19

logDebugSH :: ( HasCallStack , MonadLogger m, Show a) => a -> m () Source #
