Module CodeRay::GZip
In: lib/coderay/helpers/gzip.rb

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

Methods

gunzip   gzip  

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'))

[Source]

    # File lib/coderay/helpers/gzip.rb, line 16
16:     def GZip.gunzip s
17:       Zlib::Inflate.inflate s
18:     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
