Here is the code so far:

`
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
`

Produces this error message:

`
cw-replace.rb:44: private method `ukquotes' called for
# (NoMethodError)
        from cw-replace.rb:43:in `each'
`

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.

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.
