Some Ruby

#Methods takes parameters as that of parameters in a script (ARGV) 

def two_args(*argv)
  a1, a2 = argv
  puts "a1 = #{a1} &  a2 = #{a2}"
end

puts two_args("one", "two")

============================================================

#File manipulation
#ARGV holds data in an array, hence the ARGV.first return the element in the 0th index
filename = ARGV.first
puts "we are going to delete the #{filename}"
puts "If you don't want that, hit CTRL-C (^C)."
puts "If you do want that, hit RETURN."

STDIN.gets.chomp

puts "opening the file..."
target = open(filename, 'w')

puts "truncating the file. Goodbye!"
target.truncate(0)

#target.close

puts "now i am going to ask you for lines"

print "line1: "
line1 = STDIN.gets.chomp
print "line2: "
line2 = STDIN.gets.chomp

puts "i am going to write these lines in the file #{filename}"
target.write(line1)
target.write("\n")
target.write(line2)
target.write("\n")
puts "Finally i am closing the file #{filename}"
target.close

##Requirement

#class Person
#  def name
#    @name
#  end
#  def name=(str)
#    @name = str
#  end
#end

##make it short

#class Person
#  attr_reader :name
#  attr_writer :name
#end

##even more shorter
class Person
  attr_accessor :name
end

person = Person.new
puts person.name = 'nir'
puts person.name
