Hi all
I’d like Ruby to open a folder, search it for files and then store all
files names of .png files in an array and close the folder. So after
this I can do anything I like with the png files in the array…
How do I do this? Thanks a lot for help.

You’ll want the class Dir, and the class method glob.
png_files = Dir.glob(File.join(path_of_folder, ‘*.png’))

Thank you so far. I’m using this in Ruby on Rails and tried the
following:
@images = Dir.glob(’/images/content/parties/photo_galleries/1/’,
‘*.jpg’)
Sadly this delivers me an empty array, but there are about 20 jpg files
in this folder… :-/
Thanks for help… Josh
Ups sorry, it doesn’t return an empty array but the following error:
cannot convert String into Integer

Try:
@images = Dir.glob('/images/content/parties/photo_galleries/1/
*.jpg’)

This is part of a RHTML file for showing all JPEG files as a list:
<% bilder = Dir["*.jpeg"] %>
This is part of a RHTML file for randomly show a picture from a
picture list like above:
<% bilder = Dir["…/*.jpeg"] %>

Thank you all, guys!
I have now the following array:
/Users/Josh/Webwork/PsyGuide.org/public/…/config/…/public/images/content/parties/photo_galleries/1/2005_10_08_-_claudias_abschieds_party-20.jpg
Is there a way to clean the path (I mean the unnecessary “/…”)?
Thanks. 
This is operating on the actual filesystem, so you have to use real
paths, not the URI for the web application. Try this:
File.join(RAILS_ROOT, ‘public’)
@images = Dir.glob(File.join(RAILS_ROOT,
‘public/images/content/parties/photo_galleries/1/’), ‘*.jpg’)
Oh, and how do I cut the RAILS_ROOT away again? So I can use the paths
in the RHTML file again…?
You might want to look at Pathname
(http://ruby-doc.org/stdlib/libdoc/pathname/rdoc/classes/Pathname.html)
It wraps alot of the File related libs into a nice package
Cheers

list_of_paths.map!{|path| File.expand_path path}
