####### Using ZipInputStream alone: #######

Zip::ZipInputStream.open("example.zip") {
  |zis|
  entry = zis.get_next_entry
  print "First line of '#{entry.name} (#{entry.size} bytes):  "
  puts "'#{zis.gets.chomp}'"
  entry = zis.get_next_entry
  print "First line of '#{entry.name} (#{entry.size} bytes):  "
  puts "'#{zis.gets.chomp}'"
}


####### Using ZipFile to read the directory of a zip file: #######

zf = Zip::ZipFile.new("example.zip")
zf.each_with_index {
  |entry, index|
  
  puts "entry #{index} is #{entry.name}, size = #{entry.size}, compressed size = #{entry.compressed_size}"
  # use zf.get_input_stream(entry) to get a ZipInputStream for the entry
  # entry can be the ZipEntry object or any object which has a to_s method that
  # returns the name of the entry.
}


####### Using ZipOutputStream to write a zip file: #######

Zip::ZipOutputStream.open("exampleout.zip") {
  |zos|
  zos.put_next_entry("the first little entry")
  zos.puts "Hello hello hello hello hello hello hello hello hello"

  zos.put_next_entry("the second little entry")
  zos.puts "Hello again"

  # Use rubyzip or your zip client of choice to verify
  # the contents of exampleout.zip
}

####### Using ZipFile to change a zip file: #######

Zip::ZipFile.open("exampleout.zip") {
  |zf|
  zf.add("thisFile.rb", "example.rb")
  zf.rename("thisFile.rb", "ILikeThisName.rb")
  zf.add("Again", "example.rb")
}

# Lets check
Zip::ZipFile.open("exampleout.zip") {
  |zf|
  puts "Changed zip file contains: #{zf.entries.join(', ')}"
  zf.remove("Again")
  puts "Without 'Again': #{zf.entries.join(', ')}"
}
