Simple CRUD program. I've been wanting to learn how to make one of these for a while, so I decided to whip together the most simple version I could - Create, Read, Update and Delete simple text files. Hopefully lots of updates coming.

cruddy_crud.rb

def create_file(file)
  target = File.open(file,'a+')
  puts "#{file} created."
end

def read_file(file)
  target = File.open(file,'r')
  puts "That file is:"
  puts target.read
end

def update_file(file)
  read_file(file)
  target = File.open(file,'a')
  puts "What do you want to add?"
  print '> '
  add = gets.chomp
  target.write(add)
  puts "Text added."
end

def delete_file(file)
  File.delete(file)
  puts "File deleted."
end

puts "Do you want to *create*, *read*, *update* or *delete* a file?"
print '> '
command = gets.chomp

puts "What file do you want to #{command}?"
print '> '
file = gets.chomp

create_file(file) if command == 'create'
read_file(file) if command == 'read'
update_file(file) if command == 'update'
delete_file(file) if command == 'delete'
