Usage:

self.nsub!(/foo/, 'bar')

nsub! is like gsub! except it logs the calling method in @changed_in. There is another difference: When using blocks, matched strings are available as block params, e.g.: # nsub!(/(match1)(match2)/) {|m1,m2|}

I wrote this because I was having problems overriding gsub and passing a block from the new gsub to super.

# File lib/nickel/nlp_query.rb, line 48
def nsub!(*args)
  if m = query_str.match(args[0])    # m will now hold the FIRST set of backreferenced matches
    # there is at least one match
    @changed_in ||= []
    @changed_in << caller[1][/(\w+)\W*$/, 1]
    if block_given?
      # query_str.gsub!(args[0]) {yield(*m.to_a[1..-1])}    # There is a bug here: If gsub matches more than once,
                                                  # then the first set of referenced matches will be passed to the block
      ret_str = m.pre_match + m[0].sub(args[0]) { yield(*m.to_a[1..-1]) }   # this will take care of the first set of matches
      while (m_old = m.dup) && (m = m.post_match.match(args[0]))
        ret_str << m.pre_match + m[0].sub(args[0]) { yield(*m.to_a[1..-1]) }
      end
      ret_str << m_old.post_match
      query_str.sub!(/.*/, ret_str)
    else
      query_str.gsub!(args[0], args[1])
