What's this?

binary?(file) private

Shamelessly stolen from the ptools gem (since RDoc cannot depend on the gem).

# File lib/rdoc/parser.rb, line 69
  def self.binary?(file)
    s = (File.read(file, File.stat(file).blksize, 0, :mode => "rb") || "").split(//)

    if s.size > 0 then
      ((s.size - s.grep(" ".."~").size) / s.size.to_f) > 0.30
    else
      false
    end
  end
