Subject: Re: Ruby Rake 'advanced' rule arguments

Anyway - yes I'm learning ... answered my own question
The miracle of subroutines and scope solves the problem and factors out 
nicely.

The below make a rule to copy tarket "[destdir]/file"s from srcdir to 
destdir

*******

def copyRule(destdir, srcdir)

  if(srcdir =~ /\/\z/)
  srcdir = $`
  end

  if(destdir =~ /\/\z/)
        # rake doesn't check both, string based
  directory(destdir)
  srcdir = $`
  end

  directory(destdir)

  regex =
  Regexp.new('^' + regexifyPath(destdir) + '\/[^\/]+\z')

  Rake::Task::create_rule( regex => [
    proc { |task_name|
      task_name =~ /\/[^\/]+\z/
      task_name = srcdir + $&
    }
    ])  do |t|
    cp t.source, t.name
  end
end
