A simplified interface to the gzip library zlib (from the Ruby Standard Library.)

Methods
Constants
DEFAULT_GZIP_LEVEL = 7
  The default zipping level. 7 zips good and fast.
Public Class methods
gunzip(s)

Unzips the given string s.

Example: 

  require 'gzip_simple'
  print GZip.gunzip(File.read('adresses.gz'))

→ show source

# File lib/coderay/helpers/gzip.rb, line 16
    def GZip.gunzip s
      Zlib::Inflate.inflate s
    end
gzip(s, level = DEFAULT_GZIP_LEVEL)

Zips the given string s.

Example: 

  require 'gzip_simple'
  File.open('adresses.gz', 'w') do |file
    file.write GZip.gzip('Mum: 0123 456 789', 9)
  end

If you provide a level, you can control how strong the string is compressed:

  • 0: no compression, only convert to gzip format
  • 1: compress fast
  • 7: compress more, but still fast (default)
  • 8: compress more, slower
  • 9: compress best, very slow

# File lib/coderay/helpers/gzip.rb, line 35
    def GZip.gzip s, level = DEFAULT_GZIP_LEVEL
      Zlib::Deflate.new(level).deflate s, Zlib::FINISH
    end
