instance method

Dir#each

dir.each { |filename| block } → dir

dir.each → an_enumerator

static VALUE
dir_each(VALUE dir)
{
    RETURN_ENUMERATOR(dir, 0, 0);
    return dir_each_entry(dir, dir_yield, Qnil, FALSE);
}

Calls the block once for each entry in this directory, passing the filename of each entry as a parameter to the block.

If no block is given, an enumerator is returned instead.

Example

d = Dir.new("testdir")
d.each  {|x| puts "Got #{x}" }

produces:

Got .
Got ..
Got config.h
Got main.rb
