Is there any way to get the name of a variable using metaprogramming (or reflection, I believe it's a synonym) in Ruby? I want something like nameof for C #.
I was looking for something like:
minha_variavel = "valor"
minha_variavel.name
=> "minha_variavel"
I tried to use several methods, but to no avail. I even used Object#object_id to work with the object, but I did not get the result I expected:
ObjectSpace._id2ref(minha_variavel.object_id)
=> "valor"
The ObjectSpace#_id2ref gets the instance itself, which is evaluated by its value. What I want is the name given to the object.
Is it possible? If it does not, what is impossible, if in other languages this kind of situation can be solved
