Sample text

Is", "on", "who", "Who"] You can compare Strings in a case-sensitive manner— this is how #sort works by default. This method works in the same way that "<=>" does (returning -1, 0, or 1), so it can be used as a part of "#sort {}" calls. Checksumming a String (MD5 or Otherwise) require 'digest/md5' Digest::MD5::new 'foobar' #=> 3858f62230ac3c915f300c664312c63f require 'digest/sha1' Digest::SHA1::new 'foobar' #=> 8843d7f92416211de9ebb963ff4ce28125932878 31 32 CHAPTER 2 Working with Strings Above, I show both MD5 and SHA1 checksum methods.

Sort_recur! is_a? sort_recur! include? This is a sample of what such a file looks like: variable1 = foo variable2 = bar variable3 = baz For the sake of simplicity, instead of a File for simulated input, this example uses a simple String with some \n (newline) separators. In plain English, those inner lines mean, “Take the current line and call the #split on it, splitting on the ‘=’ character; pass each element of the resulting two-element Array in to the block; call the #strip method on the Strings to remove any whitespace, and return the modified Array to tmp_ary.
