# 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:
# dir_to_zip = "/tmp/input"
# out_file = "/tmp/out.zip"
# zf = Zippy.new dir_to_zip, out_file
# zf.write
#
# Or:
# z = Zippy.new(directory_to_zip, output_file) { |f| f.include? 'html' }
# z.write
class Zippy
# Initialize with the directory to zip and the location of the output archive.
#
# @param [String] input_dir The location to zip as a file system relative or
# absolute path
#
# @param [String] out_file The path of the output zip file that is generated.
# @param [Block] filter An optional block with a filter that is to return true
# if the file is to be added.
def initialize input_dir, out_file, &filter
@input_dir = input_dir.
gsub(/[\/\\]$/, '').
gsub(/\\/, '/')
@out_file = out_file
@filter = block_given? ? filter : lambda { |f| true }
end
# Zips the input directory.
