Description

A default layout for built-in sinks

This module layouts a log message by the following format:

  {yyyy}-{MM}-{dd} {HH}:{mm}:{ss}.{SSS} [{SEVERITY}] {NODE} {PID} {MODULE}:{FUNCTION}:{LINE} [{HEADER(KEY=VALUE)}*] {MESSAGE}\n

NOTE

This module is provided for debuging/testing purposes only. The message format is not customizable. And no overload protection exists (e.g. if log message is too large, the caller process may hang).

EXAMPLE

  > error_logger:tty(false). % Suppresses annoying warning outputs for brevity
 
  > Layout = logi_builtin_layout_default:new().
  > {ok, _} = logi_channel:install_sink(logi_builtin_sink_io_device:new(foo, [{layout, Layout}]), info).
  > logi:info("hello world").
