April 2, 2012 10:28:31.039

Today's Smalltalk 4 You looks at logging with Toothpick in VisualWorks and Pharo (the code is available for VA, and Dolphin as well - and the VW code works in ObjectStudio, while the Squeak code is what I used in Pharo).

The logging code used in the screencast, which you can find documented at metaprog:

"create a logger"
logger1 := TranscriptLogger new
			name: 'My first Logger'.

"where do logging events go"
logger1 format: SimpleLoggingFormatter defaultFormat.

"logging policy"
logger1 policy: (LoggingPolicy category: #debug level: #debug).

"register the logger"
(LoggingMultiplexer current)
	addLogger: logger1.

"Start the loggers"
(LoggingMultiplexer current) startAllLoggers.

	category: #debug 
	level: #warn 
	message: 'using obsolete protocol'.

LoggingMultiplexer current stopAllLoggers
