Subject: Running wordlist.rb code from "why's (poignant) Guide to Ruby"

Hi,

I am just starting Ruby as my first programming language. I have this
version installed on my Linux: ruby 1.9.3p194

While reading this book, I tried this example:

wordlist.rb:

code_words = {
  'Milkshake' => 'See what you mean to me, sweet cakes and milkshakes',
  'Strawberry' => 'People moving all the time, inside a perfectly
straight line, don't you wanna curve away?'
}

and code.rb has:

require 'wordlist'

# Get the evil idea and swap in code words
print "Enter your new idea: "
idea = gets
  code_words.each do |real, code|
    idea.gsub!( real, code )
  end

# Save the jibberish to a new file
print "File encoded, Please enter a name for this idea: "
idea_name = gets.strip
  File::open ( "idea-" + idea_name + ".txt", "w" ) do |f|
  f << idea
end

--------------------------

Running code.rb gives errors:

./code.rb:13: syntax error, unexpected ',', expecting ')'
  File::open ( "idea-" + idea_name + ".txt", "w" ) do |f|
                                            ^
./code.rb:13: syntax error, unexpected ')', expecting $end
  File::open ( "idea-" + idea_name + ".txt", "w" ) do |f|
                                                  ^

Any help would be great.
