require 'zip'
# This is a simple example which uses rubyzip to
# recursively generate a zip file from the contents of
# a specified directory. The directory itself is not
# included in the archive, rather just its contents.
#
# Usage:
# directoryToZip = "/tmp/input"
# outputFile = "/tmp/out.zip"
# zf = ZipFileGenerator.new(directoryToZip, outputFile)
# zf.write()
class ZipFileGenerator
# Initialize with the directory to zip and the location of the output archive.
def initialize(input_dir, output_file)
@input_dir = input_dir
@output_file = output_file
end
# Zip the input directory.
def write
entries = Dir.entries(@input_dir)
entries.delete('.')
entries.delete('..')
io = Zip::File.open(@output_file, Zip::File::CREATE)
write_entries(entries, '', io)
io.close
end
# A helper method to make the recursion work.
