Zippo

Zippo is a fast zip library for ruby.

A benchmark is available.

Add this line to your application's Gemfile:

gem 'zippo'

And then execute:

$ bundle

Or install it yourself as:

$ gem install zippo

It can be called in block form:

Zippo.open("file.zip") do |zip|
  str = zip["file.txt"]
  other = zip["other/file.txt"]
  puts str
end

Or without a block:

zip = Zippo.open("file.zip")
puts zip["file.txt"]
zip.close

Files can be inserted into the zip using the insert method. Note that no data will be written until the ZipFile is closed:

zip = Zippo.open("out.zip", "w")
zip.insert "file1.txt", "path/to/1.txt"
zip.insert "file2.txt", "path/to/2.txt"
zip.close

zip.insert "out.txt", "something.txt"

zip["other.txt"] = "now is the time"

io = File.open("foo.dat")
zip.insert "data.dat", io

Inserting zip data from one file into another allows the compressed data to be reused from the original zip file (avoiding uncompression and recompression):

other = Zippo.open("other.zip")
zip.insert "final.bin", other["final.bin"]
