Colog.Actions

String actions

logStringStdout :: MonadIO m => LogAction m String

Action that prints String to stdout.

logStringStderr :: MonadIO m => LogAction m String

Action that prints String to stderr.

logStringHandle :: MonadIO m => Handle -> LogAction m String

Action that prints String to Handle.

withLogStringFile :: MonadIO m => FilePath -> (LogAction m String -> IO r) -> IO r

Action that prints String to file. Instead of returning LogAction it's implemented in continuation-passing style because it's more efficient to open file only once at the start of the application and write to Handle instead of opening file each time we need to write to it.

Opens file in AppendMode.

ByteString actions

logByteStringStdout :: MonadIO m => LogAction m ByteString

Action that prints ByteString to stdout.

logByteStringStderr :: MonadIO m => LogAction m ByteString

Action that prints ByteString to stderr.

logByteStringHandle :: MonadIO m => Handle -> LogAction m ByteString

Action that prints ByteString to Handle.

withLogByteStringFile :: MonadIO m => FilePath -> (LogAction m ByteString -> IO r) -> IO r

Action that prints ByteString to file. See withLogStringFile for details.

logTextStderr :: MonadIO m => LogAction m Text
