Get the name of the currently executing method

Even better than my first answer you can use __method__:

class Foo
  def test_method
    __method__
  end
end

This returns a symbol – for example, :test_method. To return the method name as a string, call __method__.to_s instead.

Note: This requires Ruby 1.8.7.

Depending on what you actually want, you can use either __method__ or __callee__, which return the currently executing method's name as a symbol.

On ruby 1.9, both of them behave identically (as far as the docs and my testing are concerned).

On ruby 2.1 & 2.2 __callee__ behaves differently if you call an alias of the defined method. The docs for the two are different:

• __method__: "the name at the definition of the current method" (i.e. the name as it was defined)
• __callee__: "the called name of the current method" (i.e. the name as it was called (invoked))

Test script:

require 'pp'
puts RUBY_VERSION
class Foo
  def orig
    {callee: __callee__, method: __method__}
  end
  alias_method :myalias, :orig
end
pp( {call_orig: Foo.new.orig, call_alias: Foo.new.myalias} )

1.9.3 Output:

1.9.3
{:call_orig=>{:callee=>:orig, :method=>:orig},
 :call_alias=>{:callee=>:orig, :method=>:orig}}

2.1.2 Output (__callee__ returns the aliased name, but __method__ returns the name at the point the method was defined):

2.1.2
{:call_orig=>{:callee=>:orig, :method=>:orig},
 :call_alias=>{:callee=>:myalias, :method=>:orig}}
