require "active_support/core_ext/string/output_safety"
module ActionView
# Used as a buffer for views
#
# The main difference between this and ActiveSupport::SafeBuffer
# is for the methods `<<` and `safe_expr_append=` the inputs are
# checked for nil before they are assigned and `to_s` is called on
# the input. For example:
#
# obuf = ActionView::OutputBuffer.new "hello"
# obuf << 5
# puts obuf # => "hello5"
#
# sbuf = ActiveSupport::SafeBuffer.new "hello"
# sbuf << 5
# puts sbuf # => "hello\u0005"
#
class OutputBuffer < ActiveSupport::SafeBuffer # :nodoc:

end

return self if value.nil?

end

def safe_expr_append=(val)

end

def initialize(block)
