Nice and simple logging. There are eight messages for logging based on severity. These correspond to the eight levels defined in syslog: 7 - debug (Debug-level messages)6 - info (Informational)5 - notice (Normal but significant Condition)4 - warning (Warning Condition)3 - err (Error Condition)2 - crit (Critical Conditions)1 - alert (must be handled immediately)0 - emerg (System is unusable)The absolutely easiest way to log is like this: SLLog warn: 'Oopsidaisy' ...this utilizes the class SLLog as a facade onto a singleton that you reach with "SLLog instance". You can also register an instance in global #Log like: SLLog useGlobalLog: true...and then you can use: Log warn: 'Hey, nicer to type!' We only need to include the actual message in the string, timestamp etc is added automatically.You can also explicitly supply a "sender" object which can be anything you like, a symbol or a specific domain object even: SLLog warn: 'Yowsa' sender: #email SLLog uses printString on the sender when producing the log entry, so if you use domain objects - make sure they have a unique printOn: method defined so that you can distinguish them. See class side category "logging" and "logging shorthand" for the available log messages. By default there is a single emitter registered that logs on Transcript, you can turn this default initialization off (for new SLLog instances) with: SLLog useTranscript: false You can also use addTranscript/removeTranscript, addMorphic/removeMorphic etc to add and remove known emitters: SLLog removeTranscript; addMorphic; addSyslogThe above removes default transcript emitter and adds an SLLogMorph as an emitter (and opens it), and also a SLSyslogSender emitter that will log onto localhost using UDP on port 514, see its class comment for details. You can set a threshold for the syslog levels that should be logged onto Transcript (levels <= threshold are logged) using: SLLog transcript transcriptMaxLevel: 4 ...and you can set a threshold for raising a notif
