Hi,
what' s the best way to detect if a Dir entry is a directory or file? I' m doing a Dir.foreach blabla |x|.
I' m trying to use 'directory?', but it doesn' t work the way I use it.

Thanks,
Alex.

Dir.foreach yields just basenames. You'll need to prefix the
directory name to them.

Dir.foreach(blabla) {|x| x = File.join(blabla, x); p x if File.directory?(x)}

Or, Dir.glob(File.join(blabla, "*/")) returns an array of the directories.

Dir.new('./').entries.partition {|i| File.directory?(i))}
=> [
  [".", "..", "log", "src", "conf", "_darcs", "public", "script", "templates"],
  ["README", "run.rb.save", "run.rb"]

Thanks,
it works. I just offered names to the 'directory?'-method.
