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(inputDir, outputFile)
@inputDir = inputDir
@outputFile = outputFile
end
# Zip the input directory.
def write()
entries = Dir.entries(@inputDir); entries.delete("."); entries.delete("..")
io = Zip::File.open(@outputFile, Zip::File::CREATE);
writeEntries(entries, "", io)
io.close();
end
# A helper method to make the recursion work.
private
def writeEntries(entries, path, io)
entries.each { |e|
zipFilePath = path == "" ? e : File.join(path, e)
diskFilePath = File.join(@inputDir, zipFilePath)
puts "Deflating " + diskFilePath
if File.directory?(diskFilePath)
io.mkdir(zipFilePath)
subdir =Dir.entries(diskFilePath); subdir.delete("."); subdir.delete("..")

io.get_output_stream(zipFilePath) { |f| f.puts(File.open(diskFilePath, "rb").read())}
