Hello all, and happy new year,

There are three Logging packages for Squeak that I know of.

1. SimpleLog
2. Toothpick
3. LogEngine
there is also a Null logger.

This package "Logging", available from SqueakMap and in Universes, is
slightly higher level 'front end' api to these logging back ends.

best regards

Keith

from the class comment

Convenient usage: 'annotated values'

self log x: 10 y: 20 z: 30.

To select a specific log severity level (i.e. not the temporary one
featured above).

self log info x: 10 y: 20 z: 30.

To log the current method's input parameters.

Rectangle-#corner: topLeftPoint extent: heightWidthPoint

self log debug this.

would be the same as

self log corner: topLeftPoint extent: heightWidthPoint.

To log the current methods variables:

self log debug vars instance.
