You can copy the necessary terminfo descriptions to remote hosts.

• On the local system, dump the description to text format:

  infocmp xterm-256color > xterm-256color.ti

  infocmp screen-256color > screen-256color.ti

• Copy to the remote host and compile:

exceptions = []
tree = {}
ObjectSpace.each_object(Class) do |cls|
  next unless cls.ancestors.include? Exception
  next if exceptions.include? cls
  next if cls.superclass == SystemCallError # avoid dumping Errno's
  exceptions << cls
  cls.ancestors.delete_if {|e| [Object, Kernel].include? e }.reverse.inject(tree) {|memo,cls| memo[cls] ||= {}}
end

Sandi Metz’ rules for developers

1. Your class can be no longer than a hundred lines of code.
2. Your methods can be no longer than five lines of code
3. You can pass no more than four parameters and you can't just make it one big hash.
4. In your controller, you can only instantiate one object, to do whatever it is that needs to be done.
5. Your view can only know about one instance variable.
6. Your Rails view should only send messages to that object i.e., no Demeter violations.[ "thunder dome principal". Translated: one model in, one model out! ]
7. Rules are meant to be broken if by breaking them you produce better code. [ ...where "better code" is validated by explaining why you want to break the rule to someone else. ]
