class ZipFileGenerator
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()
Public Class Methods
new(input_dir, output_file)

Initialize with the directory to zip and the location of the output archive.
# File lib/cs/bdd/zip.rb, line 15 def initialize(input_dir, output_file) @input_dir = input_dir @output_file = output_file end
Public Instance Methods
write()

Zip the input directory.
# File lib/cs/bdd/zip.rb, line 21 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
Private Instance Methods
write_entries(entries, path, io)

A helper method to make the recursion work.
# File lib/cs/bdd/zip.rb, line 34 def write_entries(entries, path, io) entries.each do |e| zip_file_path = path == '' ? e : File.join(path, e) disk_file_path = File.join(@input_dir, zip_file_path) if File.directory?(disk_file_path) io.mkdir(zip_file_path) subdir = Dir.entries(disk_file_path) subdir.delete('.') subdir.delete('..') write_entries(subdir, zip_file_path, io) else io.get_output_stream(zip_file_path) { |f| f.puts(File.open(disk_file_path, 'rb').read) } end end end
