Zippo

Zippo is a fast zip library for ruby.

A benchmark is available.

Installation

Add this line to your application's Gemfile:

gem 'zippo'

And then execute:

$ bundle

Or install it yourself as:

$ gem install zippo

Usage

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

Inserting archive members

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

By path

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

Directly from a string buffer

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

By IO

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

From another zip file (direct stream copy)

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"]

TODO

implement date handling
implement unix attribute handling
