How to get the name of the calling method?

Use caller_locations(1,1)[0].label (for ruby >= 2.0)

Edit: My answer was saying to use __method__ but I was wrong, it returns the current method name.

puts caller[0]

or perhaps...

puts caller[0][/`.*'/][1..-2]

In Ruby 2.0.0, you can use:

caller_locations(1,1)[0].label

It's much faster than the Ruby 1.8+ solution:

caller[0][/`([^']*)'/, 1]

Will get included in backports when I get the time (or a pull request!).
