Well, those two methods won't give you what you want, if you really want
to capitalize the first letter of every word in a sentence. Also, if you
just want to capitalize the first letter of the string, the built-in
capitalize method will do that for you:
'some string'.capitalize => 'Some string'
If you want to capitalize each word in a string, you could do this (a naive
approach):
'some string'.split(' ').map {|w| w.capitalize }.join(' ')
If you then wanted to make this built-in to the String class, as you were
referencing in your original request, you could add a method that does this
to the String class by reopening it (like the example you posted):
class String
def cap_words
self.split(' ').map {|w| w.capitalize }.join(' ')
end
end
You could put this snippet of code in a file in config/initializers or (as
my preferred approach would be) in a file in lib (like
lib/extensions/string.rb) that is then required via an initializer (like
config/initializers/requires.rb): require 'extensions/string'
Now you have reopened String to add this method. Whether that's a good idea
is another matter entirely. :)
