Current implementation creates a Singleton class and prevents marshaling

[mynock]

This line:
eval "class <<str; def html_truncated?; #{opts[:was_truncated]} end end"

causes a singleton class to be returned which prevents the field from being serialized using Marshal (and therefore prevents it from being cached using dalli/memcached).

OK, thanks for the information. What do you suggest?

Wouldn't creating a class inheriting from String with htm_truncated? method solve this problem?

Something like:

class HTML_Truncator::Output < String
  def initialize(str, truncated)
    @truncated = truncated
    super(str)
  end

  def html_truncated?
    @truncated
  end
end
