+title: XMMS-Ruby and M3U
+---
+
+<p>
+I wrote this little snippet of code in response to an email, and I thought it might be useful for other people.
+</p>
+
+<blockquote>
+<p>
+<i>Basically, I'm trying to write some code that will connect to a running       
+XMMS session, grab the playlist and write out a .pls or a .m3u file.          
+Unfortunately, while XMMS can do this in a single operation, their API        
+doesn't seem to have a simple hook to do this.                               </i>
+</p> 
+                                                                                
+<p>
+Unfortunately, there's nothing in the remote API that lets you do that          
+in a single call.  But it should be pretty easy to write; just iterate          
+over the list and print out the necessary lines for each entry.                 
+Something like this:

+  module Xmms                                                                   
+    class Remote

+      #                                                                         
+      def to_m3u                                                                
+        "#EXTM3U\n" + playlist.map { |title, file, time|                        
+          "#EXTINF:#{time / 1000},#{title}\n#{file}"                            
+        }.join("\n")                                                            
+      end                                                                       
+    end                                                                         
+  end
+</pre>                                                                           
+

+Then, to save a playlist, you can just do the following:                        
+                                                                                </p>

+<pre>
+  xmms = Xmms::Remote.new                                                       
+  File::open('path/to/output.m3u', 'w') { |out| out.puts xmms.to_m3u }          
+                                                                                </pre>

+Hope this helps...
