Error: "undefined local variable or method '__method__'"

[Daniel Huffman]

How do you programmatically get the current method name?

For example, in Ruby, you can do something like:

def some_method(params)
  logger.warn("#{self.class.name}##{__method__} -> params: #{params}")
  # ..
end

.. or ..

def some_method
  # ..
  condition = ...
  logger.warn("#{self.class.name}##{__method__} -> condition met!") if condition
  # ..
end

See also: https://github.com/crystal-lang/crystal/issues/3552 for a "we could add" potential solution:

def foo 

  # a.k.a. __method__

  {{@def.name.stringify}} # => "foo"

end

If you want to do something that's kind of a kludge you can use caller, to get the current call stack.

p caller[4] if condition
