In repo controller entry action, show the page for the file even if it's binary (so user still has access to history etc links). This makes it possible to use the entry action as the default when a file is clicked on

module CodeRay
  
  # A simplified interface to the gzip library +zlib+ (from the Ruby Standard Library.)
  module GZip
    
    require 'zlib'
    
    # The default zipping level. 7 zips good and fast.
    DEFAULT_GZIP_LEVEL = 7
    
    # Unzips the given string +s+.
    #
    # Example:
    #   require 'gzip_simple'
    #   print GZip.gunzip(File.read('adresses.gz'))
    def GZip.gunzip s
      Zlib::Inflate.inflate s
    end
    
    # 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
    def GZip.gzip s, level = DEFAULT_GZIP_LEVEL
      Zlib::Deflate.new(level).deflate s, Zlib::FINISH
    end
