PureRubyZip

A pure-Ruby ZIP file decompressor/compressor. VERY inefficient, possibly buggy. Mostly for entertainment value.

Add this line to your application's Gemfile:

gem 'pure_ruby_zip'

And then execute:

$ bundle

Or install it yourself as:

$ gem install pure_ruby_zip

This comes with a command-line script. Run it like so:

pure-ruby-zip test123.zip

You can also include this in your own program.

require "pure_ruby_zip"

To pre-process a ZIP file (cache the filenames and offsets):

z = ZipFile.new "test12.zip"

To get a list of extractable files:

z.items

To extract a file by name:

file_data = z.decompress_file "test1.txt"

To extract all files:

file_names_and_data = z.decompress_all_files "test12.zip"

To extract all files, and save them to disk:

z.decompress_all_files_to_disk "test12.zip"

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
