Well I got this script:

puts “Do you feel, good, bad, or neutral?”

  feelings = gets.chomp

  STDOUT.flush

      puts "You are feeling " + feelings

and I want to add the name class from this script:

puts “Hello, what is your name?”

  name = gets.chomp

  STDOUT.flush

      puts "Hello, " + name

How would I do that?

If that’s the whole “script”, ‘name’ is a variable, not a class.

Again – find and work through a tutorial on basic Ruby.

That dog wouldn’t bark :slight_smile:

Maybe you should ask a more specific question, or run through a
basic tutorial on Ruby first.

hello anthony,

first, i completely agree with hassan that a basic ruby tutorial is
absolutely the best place to start. there are many very good ones
available - do a quick google search for “ruby tutorial.”

second, if i understand your question - try this:

#############
class NameGetter
attr_reader :name
def initialize
puts “Hello, what’s your name?”
@name = gets.chomp
puts "Hello, " + @name
end
end #class

class NameAndFeelingGetter
def initialize
## now you “call a class from another script…”
namegetter = NameGetter.new
## and get the “name” attribute
name = namegetter.name
##
puts “How do you feel?”
feelings = gets.chomp
puts “Well, #{name}, sounds like you’re feeling #{feelings}”
end
end #class

nfg = NameAndFeelingGetter.new
###############

then run the program…

happy ruby-ing…
