Question

I’m trying the following tutorial: http://henrik.nyh.se/2007/03/ruby-wordwrap-method

It has a block that needs to be added somewhere I think outside of the helper:

class String
  # Replace the second of three capture groups with the given block.
  def midsub(regexp, &block)
    self.gsub(regexp) { $1 + yield($2) + $3 }
  end
end

Where should that be located in the rails 3 app? Thanks

UPDATE

Added /lib/midsub.rb

# Needed for html_format try 3
class String
  # Replace the second of three capture groups with the given block.
  def midsub(regexp, &block)
    self.gsub(regexp) { $1 + yield($2) + $3 }
  end
end

application.rb

config.autoload_paths += %W(#{config.root}/lib)

Answer 1

you can add that code inside a file, let’s say ‘my_string.rb’ in the /config/initializers folder
