One final note/question, would be, is there a page or location on your wiki (I have not found one) or would it not be helpful to have it, where useful and curious queries and formatting strings could be submitted?  Just a thought.

Is there any way to do bitwise operations in the CRITERIA field?

I am trying to store a DWORD type var, so I want to do:

( %FIELD% & 2 ) GREATER 0

Release 3.0beta 3

    * GUID's for queries
    * main menu command for refreshing @scheme queries: Library/Playlist Tree/Refresh/* (you can refresh a query, for its side effects such as creating a new playlist and playing it with the new playlist interaction commands below)
    * for-each-playlist-entry can now take an integer playlist index OR a playlist name to specify which playlist
    * (in-library? handle)
    * (handle-test handle filter-string) - e.g. (handle-test handle "rating GREATER 3")
    * (mainmenu mainmenu-fun-string)
    * (playlist-contextmenu contextmenu-fn-string [playlist-index])
    * (contextmenu contextmenu-fn-string handle-list)
    * (playing-playlist)
    * (active-playlist)
    * (find-or-create-playlist name) => returns a playlist-index
    * (add-to-playlist handle [playlist-index] [item-index]) => if no playlist-index is specified, active playlist is assumed.
    * (clear-playlist [playlist-index])
    * (activate-playlist playlist-index)
    * (play-from-playlist [playlist-index] [item-index])

;;; Fill *Scheme* playlist with an hours worth 
(let ((playlist-index (find-or-create-playlist "*Scheme*"))
      (total-time 0))
  (clear-playlist playlist-index)
  (for-each-db-entry
   (lambda (handle) 
     (let ((len (get-length handle)))
       (if (< (+ len total-time) (* 60 60))
	   (begin
	     (add-to-playlist handle playlist-index)
	     (set! total-time (+ total-time len))))))
   "rating GREATER 3"
   "$rand()")
  (activate-playlist playlist-index)
  (play-from-playlist playlist-index))

;;; Show properties of all playlist entries
(let ((the-list (list)))
  (for-each-playlist 
   (lambda (n) 
     (for-each-playlist-entry 
      n
      (lambda (handle) 
	(set! the-list 
	      (cons handle the-list))))))
  (contextmenu "Properties" the-list))

Am I being stupid?  I loaded this plugin and I don't get the panel that all of the screenshots seem to show.  Is there some place I have to go to activate it?  I saw somewhere that you need to activate it in Columns UI but I don't know how do do that.

Are there any good tutorials for the new scheme language you're using? I'm curious about how powerful it is. Can it, for example, rename and move files between playlists automatically?

I'm using a tag, INVOLVED PEOPLE LIST, to display info about all involved people (duh). The syntax I use is

name1 (role1); name2 (role2); name3 (role3);

etc. Now, I want to make a query in foo_playlist_tree that displays all the different persons. If I just use %involved people list%, I get a single record with all of the involved people for any given track, and not one record for each person. Does anybody know how I can do this? (I only want the names, not the names and the roles.)

It gets more advanced after that - I want sub"folders" with their roles, and after that, various albums or something like that. I can do the latter myself, but how do I extract what is within each parenthesis?

Are you trying to do this using only the foobar2000 titleformatting stuff, or are you doing it in scheme?

What's scheme? Let's go for foobar2000 titleformatting.  Unless it's impossible, of course. I'm not familiar with scheme.

I'm having problems getting this to work with PanelsUI v0.9. I've installed the component and the library dlls in the correct places and the component options are there in the preferences.

From here I go to edit my layout and include a panel using $panel and making the panel Playlist Tree. When I click OK or Apply things go crazy, CPU usage jumps to 99% and fb2k's footprint starts rising rapidly. The pop-up asking for me to join the user map appears but I cannot click yes or no on it. I try waiting a while but the memory usage hits 300mb and fb2k says it's not responding so I have to stop the process from running.

Is there a fix to this, what's the likely cause? Are there known component incompatibilities?

(add-to-playlist handle [playlist-index] [item-index]) => if no playlist-index is specified, active playlist is assumed.
