Subject: Re: Return actual files only not directories, using Pathname..

From: Brian Wallace [mailto:draygen80@gmail.com] 
#  I'd like to use Pathname, 

Pathname is a very nice façade for a lot of file things ;)

# to return only actual filenames in the array...
# But I rather like Pathname ... Since I can use it like this:
# a = Pathname("/Path")
# b = a.children
# puts b[1]   #==>  "/Path/file1.txt"
# b[1].read   #==>  "This is data in a file named file1.txt"
# puts b[2] #==> "/Path/file2.txt"
# .....

try passing a boolean arg to children, eg

  b = a.children(false)



# Does anyone have any tips on how I could use Pathname to 
# return files only, and not directories?

*nixism, they're simply all files, you'll have ask more.

try #file? or #directory?, eg

   b[1].file?

   b[1].directory?


warning: be careful when mixing result of #children(false) with other pathname methods.

on your case, to get only the files (non-dir ie), i'd probably just do,

  b = a.children.select do |path|
        path.file?
      end

and to get a list of the names (as strings ie)

  b.map do |path| 
    path.basename.to_s 
  end


and if you want to get a separate list of files and dirs, try partition, eg

  files, dirs = a.children.partition do |path|
                  path.file?
                end
