@example

# good if AllowForAlignment is true
name      = "RuboCop"
# Some comment and an empty line

website  += "/rubocop/rubocop" unless cond
puts        "rubocop"          if     debug

# bad for any configuration
set_app("RuboCop")
website  = "https://github.com/rubocop/rubocop"

# good only if AllowBeforeTrailingComments is true
object.method(arg)  # this is a comment

# good even if AllowBeforeTrailingComments is false or not set
object.method(arg) # this is a comment

# good with either AllowBeforeTrailingComments or AllowForAlignment
object.method(arg)         # this is a comment
another_object.method(arg) # this is another comment
some_object.method(arg)    # this is some comment
