Don't understand NoMethodError

[Michael Lommel]

Here is the code so far:

<code>
require 'rubygems'
require 'fastercsv'
require 'highline/import'


def ukquotes(the_string)
#RTF specific: converting double to single quotes
the_string.gsub! /\\'d2(.*)\\'d3/m, "\\'d4$1\\'d5"
the_string.gsub! /(\W)'/, "$1\\'d4"
the_string.gsub! /'(\W)/, "\\'d5$1"
the_string.gsub! /(\W)d"/, "$1\\'d4"
the_string.gsub! /"(\W)/, "\\'d5$1"
the_string.gsub! /(\w)'(\w)/, "$1\\'d5$2"
end

def ukspell(the_string)
#Converting US to UK spelling
csvdata=File.open("UK-US_spellingdiff.csv", "r")
FasterCSV.parse(csvdata) do |row|
usword, ukword = *row
the_string.gsub! /\b#{usword}\b/, '\b#{ukword}\b'
end
end

unless File.exists?("UK-US_spellingdiff.csv")
raise "CSV file does not exist"
break
end

if agree("You are about to perform this edit list on #{Dir.pwd}.
Proceed?", true)
directory = ask("Name of directory to write edited files to? ",
lambda{|q| q.gsub /\W/, '_'})
else
break
end

unless agree("Will write to:#{Dir.pwd}/#{directory}. Proceed?", true)
break
end


Dir.mkdir("#{Dir.pwd}/#{directory}")

Dir.glob("*.rtf").each do |filename|
newfile = File.open(filename, "r"){|f| f.read}.ukquotes.ukspell
newfilename = "CT_CW_"+ filename
File.open(directory/newfilename, "w"){|n| puts(newfile)}
end
</code>

Produces this error message:

You're defining #ukquotes in main (like a global function) but you use
it as an instance method. Either place it in class String or call it
like a function.

Here is the code so far:

newfile = File.open(filename, "r"){|f| f.read}.ukquotes.ukspell

Produces this error message:

<code>

from cw-replace.rb:43:in `each'

In the line shown above, you read the contents of a file into a
String, then try to call the ukquotes() method on that String.

You didn't define that method for Strings though. Instead, you
defined it to have the String passed in as an argument.

Thus, you probably want to rewrite that line as something like:

newfile = ukspell(ukquotes(File.read(filename)))

I hope that helps.
