I don't know about rdoc, but perhaps the following might help.
See first class Test and usage, to find out if this is
what you need

#!/usr/bin/env ruby

#-----------------------------------------------
#-----------------------------------------------
module MyAccessor
def my_attribute (nou, defval=nil)
if defval == nil
code ="def #{nou} (s=nil)
@#{nou} = s || @#{nou}
end"
elsif defval.class==String
code ="def #{nou} (s=nil)
@#{nou} = s || @#{nou} || '#{defval}'
end"
else
code ="def #{nou} (s=nil)
@#{nou} = s || @#{nou} || #{defval}
end"
end
puts "defining ", code
class_eval code
end # def my_attr
end # module

#----------------------------------------
class Test

extend MyAccessor

my_attribute(:color, "red")
my_attribute(:width, 20)
my_attribute(:text, "no name")

def initialize (&block)
instance_eval(&block)
end
end

#----------------------------------
# usage

puts " -------------- "
t = Test.new {
color "blue"
}
puts " -------------- "

puts t.color # => blue
puts t.width # => 20
puts t.text # => no name

t.width 50

puts t.width # => 50
