Loop through files in a directory

ruby-talk
1

I know this is a nub question, but the documentation on ruby is
terrible.

How do I loop through all of the files in a directory?

Thanks for your help.

Have a look at Find.find and Dir.each.

harp:~ > ls dir
   a b c

   harp:~ > cat a.rb
   class Dir
     def self.ls dir, glob = File.join('**', '**'), &block
       ret = unless block
       Dir.glob(File.join(dir, glob)) do |entry|
         block ? block.call(entry) : ret.push(entry)
       end
       ret
     end
   end

   Dir.ls 'dir' do |entry|
     puts entry
   end

   entries = Dir.ls 'dir'
   p entries

   harp:~ > ruby a.rb
   dir/a
   dir/b
   dir/c
   ["dir/a", "dir/b", "dir/c"]

def GetRecursiveFileList ( dirname )
    results = Array.new
    # both methods should work the same (I think one returns the directory
names in addition to the files)
    use_method = 0
    if use_method == 0
        Dir["#{dirname}/**/**"].each do | thisfile |
            thisfile.gsub! ( /\// , '\\' )
            results.push ( thisfile )
        end
    else
        require 'find'
        Find.find ( dirname ) do | thisfile |
            thisfile.gsub! ( /\// , '\\' )
            results.push ( thisfile )
        end
    end
    return results
end
