[F-Script-talk] embedded question

[ackerman <rd...@pa...>]

i am using the fscript palette to put a fscript view on my apps main 
window.
when i do a 'sys browse' in it, in the left column i see 'sys = <an 
instance of System>'.
Where are the objects of my program? shouldn't i see them there?

i forgot to mention that i can use 'select view' to click on an object 
in my gui and see its attributes.
but what i was interested in is a list of all the objects in my program 
-- not just gui objects that i can see in the interface.

You can create an FSInterpreter-object and set objects via
the setObject:forIdentifier: method. Something like: 

interpreter = [[FSInterpreter alloc] init]
[interpreter setObject: myImportantObject forIdentifier: @"obj1"];
...
[interpreter browse];

now you should see "obj1" in the left column.

i was hoping to avoid this level of manually adding code to inspect an 
object.
i want to type 'sys browse' in the FSInterpreterView and see a list of 
instances of all allocated objects, preferably listed by class.
the docs seem to show this happening, but i don't see any object 
instances in my object browser.
so i am wondering what i have to do to see my apps objects in the 
browser that is embedded in my app.

Thanks for replying ---

Hi,

This feature is not available in F-Script. I would like to add it but =20=

I have no idea about how to implement it (i.e. how to get all the =20
instances in the current application).

Does someone know how to do it ?

Cheers,

I'm no expert on ObjC or F-script so I'm not sure if this would work...

But how about using a category to override NSObject's retain method (or=20=

maybe
alloc or init) that would send a message to some sort of tracker object
while also doing the work of retain (which is hopefully well understood
by someone outside of Apple)

sorry that I don't have anything more than a vague notion...

vague notions are better than none.
couldn't the override just call NSObject's 'retain' method (or 'alloc' 
or 'init') - we wouldn't have to know its details.
does anyone know of any code/plugin that does browse objects? that 
might give us a clue.

is crawling the heap looking for objects out of the question?
(not that i know how)
