Turning Tracing On and Off
func() begin local j := self.title; :Bar(); :Foo(); endWith
trace
set to 'functions
, the Inspector prints (along with quite a bit of other information)
Sending Bar(5) to #4410D81 => 1 Sending Foo() to #4410D81 => NIL => NILAs you can see, the Inspector displays the message name, parameters, the object getting the message, and the return result. The final line shows the return result of the entire function.
As you would expect, with trace
set to true
, the Inspector prints more:
get #4412199 / #60084DC5.title = #600850A5 Sending Bar(5) to #4412199 => 1 Sending Foo() to #4412199 => NIL => NILThe
get
line signifies an access to a slot. The number before /
is the address of the frame where the search begins (self
in this case). The number just after /
is the address of the frame in which the slot was actually found (they might well be different due to inheritance). The value found in the slot follows the =
. The format, therefore, is:
get
frameSearched/
frameSlotFoundIn.slotName=
slotValue
