Checks if empty lines exist around the bodies of ‘begin` sections. This cop doesn’t check empty lines at ‘begin` body beginning/end and around method definition body. `Style/EmptyLinesAroundBeginBody` or `Style/EmptyLinesAroundMethodBody` can be used for this purpose.

Examples:


# good

begin
  do_something
rescue
  do_something2
else
  do_something3
ensure
  do_something4
end

# good

def foo
  do_something
rescue
  do_something2
end

# bad

begin
  do_something

rescue

  do_something2

else

  do_something3

ensure

  do_something4
end

# bad

def foo
  do_something

rescue

  do_something2
end
