MetaLink invocation with method returned value

Hi,

I would like to trace returned values with MetaLink, but didn't found
the correct #arguments: parameter.
Here in my example I would like to call aMethodCall:returned: with the
return value of aMethodCall:
(the method on which the link is installed)

(MyObject>>#aMethodCall:) ast
link: (MetaLink new
metaObject: myObject;
control: #after;
selector: #aMethodCall:returned: ;
arguments: #( arguments object)).

object is myObject not the returned value, value does not work, and I
didn't found any one working.

Does anyone know the correct invocation and can help me ?

Many thanks

regards,

Alain

Re: MetaLink invocation with method returned value

As far as I know return values for methods are not yet implemented. I’ve talked with Marcus, it’s planned but not the top priority. For now you can all links to the return nodes of a method.

Hi,

yes, this is on the TODO… I am last and this week focussed on stabilising Pharo5, I will come
back to my backlog of MetaLinks starting next week.

Re: MetaLink invocation with method returned value

Thank you both for your answers,

Great.
No emergency for me, it's for a POC about design by contract with
annotations I started last year and resumed recently.
As it starts working (at least it looks like), I will publish on
smalltalkhub soon so others can play with it too, tomorrow, time to
finish some tests and at least one readme .
