end

def bar

# => ["test.rb", 9]

If i is not given, or is the default value of 0, it attempts to figure out the correct value. This is useful when in combination with instance_eval. For example:

require 'rss/utils'

def foo
  p RSS::Utils.get_file_and_line_from_caller(1)
end

def bar
  foo
end

instance_eval <<-RUBY, *RSS::Utils.get_file_and_line_from_caller
def baz
  bar
end
RUBY

baz

# => ["test.rb", 8]
