class ZipFolder
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:
directory_to_zip = "/tmp/input" output_file = "/tmp/out.zip" zf = ZipFolder.new(directory_to_zip, output_file) zf.write()

Zip the input directory.

A helper method to make the recursion work.
# File lib/zip_folder.rb, line 42 def write_entries(entries, path, zipfile) entries.each do |e| zipfile_path = path == '' ? e : File.join(path, e) disk_file_path = File.join(@input_dir, zipfile_path) if File.directory? disk_file_path recursively_deflate_directory(disk_file_path, zipfile, zipfile_path) else put_into_archive(disk_file_path, zipfile, zipfile_path) end end end
