Self.method?

Hi,

We can write "self.class" to get the current object, but is it possible
to do something like a "self.method" to retrieve the currently running
method?

Cheers

Hi Aidy,

In short, no it is not possible (in an easy way) -- but just wait, and
someone smarter than me will prove me wrong. :wink: See also Kernel#caller

Hello !

In short, no it is not possible (in an easy way) -- but just wait, and
someone smarter than me will prove me wrong. :wink: See also Kernel#caller

  Based on that, you could try something as follows:

def who_am_i?
  return caller[0]
end

def meth
  p who_am_i?
end

meth

  As it returns text, you'll need some regular expression handling, but
that could help you...

Thank you, that certainly works

See! I told you that someone smarter than me would come up with a
solution! Never say never unless you want to be proven wrong rather
quickly! :wink:

Using Vince's idea:

def who_am_i?
  caller[0].match(/`([^']+)'/)[1]
end

def meth
  p who_am_i?
end

meth # => "meth"

:slight_smile:

You can also do that without a helper method:

def meth
   p caller(0)[0]
end

Note: default argument for caller is 1, which makes it start one level above.

Kind regards
