Kotlin's With, for ruby

Question

Is there any function or way to simulate this with in ruby?

It helps you to organize the code that acts over the same object, something like:

with(callDao) {
            whenever(deleteAll()).thenComplete()
            whenever(insertAll(any())).thenComplete()
}

vs

            whenever(callDao.deleteAll()).thenComplete()
            whenever(callDao.insertAll(any())).thenComplete()

Answer 1

Yes, you can build your own with using instance_eval.

def with(obj, &block)
  obj.instance_eval(&block)
end

with(" banana ") {
  puts strip
  puts reverse
}

Output:

banana
 ananab
