Today's Smalltalk Daily looks at inserting a breakpoint programmatically. To do that, you need to grab this code and file it in, and then use code like this:

"get the method"
method := Constructor class methodDictionary at: #determineClassToHandle:.
source := method getSource.
^source

"Insert the Probe"
CodeProbe
	insertProbeIntoClass: Constructor class
	selector: #determineClassToHandle:
	sourceString: source
	offset: 0
