ruby - attr_reader only working in some environments -


this applies attr_writer , attr_accessor.

i've been playing simple ruby code , following snippet not work in environments i've run it:

class human   attr_reader :name   def initialize(name)     @name = name   end end  hank = human.new("hank") hank.name

this should output "hank", in command line irb. in textmate2 , aptana studio 3, nothing outputs when run code. 3 work expected if explicitly define reader:

def name   puts @name end

when play in aptana terminal , usual terminal , type:

$ ruby -v

they both appear use same version: ruby 2.0.0p451. what's going on?

attr_reader doesn't think does.

try

puts hank.name

rather than

hank.name

and you'll see output. irb special case, shows return value of last statement executed. ruby on own won't that, prints things explicitly tell print.
