ruby-core

Hi,

I'm trying to implement a functionality that hooks on array modifications "by reference" but I find it complicated to implement such hook.

Ex :
arr = [12 , "hello" ]

arr.reverse!
arr.reverse


The first one will reverse the array by reference "same VALUE" without creating a new object but just modifying its value by its reference " same as opt_aset YARV instruction ".

The second will create a new array instance and return a different reference "VALUE" holding the change.

Is there another way that could help me implement such a hook ? possibly a method I haven't discovered yet ? I've looked at rb_ary_modify_check but it's much related to shared arrays.

I need ideas on implementing a hook that enables me to know when Ruby uses a method dispatch such as arr.reverse! and return the same reference to the object ?
