Console appender
Console is the simplest appender. It just writes the log messages
to io.stdout
or io.stderr
.
function logging.console { [destination = "stdout"|"stderr",] [logPattern = string,] [logPatterns = { [logging.DEBUG = string,] [logging.INFO = string,] [logging.WARN = string,] [logging.ERROR = string,] [logging.FATAL = string,] },] [timestampPattern = string,] [logLevel = log-level-constant,] }
logPatterns
:
A table with logPattern strings indexed by the log-levels. A logPattern specifies how the message is written.
If this parameter is omitted, a patterns table will be created with the parameterlogPattern
as the default value for each log-level. IflogPattern
also is omitted then each level will fall back to the current default setting, seelogging.defaultLogPatterns
.logPattern
:
This value will be used as the default value for each log-level that was omitted inlogPatterns
.timestampPattern
:
This is an optional parameter that can be used to specify a date/time formatting in the log message. The default is taken fromlogging.defaultTimestampPattern()
.destination
:
The destination stream, optional. The value can be either"stdout"
, or"stderr"
. The default isstdout
.logLevel
:
The initial log-level to set for the created logger.
Examples
require"logging.console" local logger = logging.console() logger:info("logging.console test") logger:debug("debugging...") logger:error("error!")
