Property short cut for read-ony instance access, but

Ruby
1

Hello,

Is there a short cut for creating a property that has read-only access
from instance variables and read/write access for derived classes?

Was looking for something like…

attr_reader :prompt
attr_writer protected :prompt

or am I doomed to do it this way…

#…
def prompt
@prompt
end

def prompt=(value)
@prompt=value
end
protected :prompt=
#…

With a little meta programming you can do

class Module
def attr_protected *names
attr_accessor *names
protected *names.map {|n| “#{n}=”}
end
end

and use it like

class A
attr_protected :foo, :bar
end

Kind regards
