[EasyMarketer]

print "What is your name? "
# This asks for the persons name.
name = gets
# This Grabs the persons name and assigns it to a variable.
puts " Your Name Is "
puts name
# This tells the person there name.
nfh = File.new("names.out", "w")
# this creates the log file.
nfh.puts name
nfh.close
# This puts there name in the log file that was created.
print "What Is your email Address? "
# this asks the user what there email is.
email = gets
# this gets the email address that they put, and assigns it to a variable.
puts " Your email Address is "
puts email
# this tells them the email address that they put in.
efh = File.new("email.out", "w")
# This creates the log file.
efh.puts email
efh.close
# This puts there email address in the log file.
print "What is your Age? "
# This asks for there Age.
age = gets
# This grabs there age, and assigns it to a variable.
puts " You are "
puts age
puts " years of age "
# This tells them there age.
afh = File.new("age.out", "w")
# This creates the log file.
afh.puts age
afh.close
# this creates the log file.
print "Do you want to know the answers you just typed? "
# Asks them a question.
answer = gets
# Grabs the answer and assigns it to a variable
puts "So your name Email and age are: "

So, do you have a lot of console users?

You should code in real Ruby style:

['name','email','age'].map{|i|print "What is your #{i}? " or [i,gets]}.map{|i|
File.open(i[0]+'.out','w').write i[1] and puts "Your #{i[0]} is: #{i[1]}"}

Beat that ;-).

Don't try and discredit him, he is obviously learning and proud of his first achievement.

Good on you bud, keep up the learning.

Just a joke, I didn't try to discredit him: his script is good. I can't even read my own script anymore

One little thing though:

nfh = File.new("names.out", "w")
# this creates the log file.
nfh.puts name
nfh.close

Can be:

File.open("names.out", "w").write(name)

File.open("names.out", "w").write(name)

Wow, I have a question did stuff change? like when a new release came out. And is that why i do not have to normally do all of that stuff? but i just dont know how to do it that way that you are doing lol. I think i need to get a more up to date book

My first Ruby script has long since bit the dust, but one last vestage of it remains: a command line menu class:

class Menu
  def initialize(opts, name)
    @opts = opts
    @name = name
    @sep = ') '
  end
  
  def display
    puts "\n#{@name} Choices:\n"
    (1..@opts.length).each { |i| puts "#{i}#{@sep}#{@opts[i-1]}\n" } 
  end
  
  def choose
    choice = 0
    while (choice.to_i < 1 || choice.to_i > @opts.length) do
      display
      print "Input #{@name} number (1-#{@opts.length}): "
      choice = gets
      raise SystemExit.new(status=0) if choice.downcase.slice(0,1) == 'q'
    end
    choice.to_i
  end
end

Sweatje that is your first Ruby script? Im going to run it and see exactly what it does This is really interesting. Im also going to be creating another thread, about rails as well, because im going to have a question lol.
Well, If everyone still has there first ruby scripts go ahead and post them lol. I want to see them as well

The whole idea was to make a quick menu for command line applications.

Here is an exaple

 require 'menu'
 phpfiles = Dir.new('.').to_a.find_all{|f| /php$/.match(f)}
 menu = Menu.new(phpfiles, 'Pick a PHP file')
 which = menu.choose
 puts "You selected "+phpfiles[which-1]

This might product output like this (depending on what php files were in the current directory):

Pick a PHP file Choices:
1) mtrcfcst.php
2) mtrcfcst_setup.php
3) frcstcmt.php
Input Pick a PHP file number (1-3):

Im confused on something can you make a web application without rails? because i know that ruby has ERB where you can enbed ruby scripts in html. by doing
<%=>include_whatever.rb<=%> etc. i think thats how i do it lol. Well, is that possible to make applications without rails? or do you need rails?

[sweatje]

$ cat .htaccess
Options +ExecCGI
AddHandler cgi-script .rb

#!/usr/bin/ruby
print "Content-type: text/html\n\n"

puts "<h1>hello world!</h1>"
