tagnavi.config questions

[jpmahala]

The tagnavi.config file is rather self-explanatory, however I would like to confirm a few things.  First, here are the two example lines:

"Example 1" artist ? year >= "2000" & artist ^ "a" : album : title
"Example 2" genre ? genre ~ "pop" : artist ? year >= "2000" : album ? year >= "2000" : title

I believe that I can read example 1 as "list all artists where the year (of the track) is greater than or equal to 2000 and the artist name begins with an 'A'".

So:
? = Filter
^ = Begins
~ = Contains
Is there an OR operator?
Is there a NOT operator?  (<> doesn't work)

In example 1, the filter is specified at only the artist level whereas the filter is specified in example 2 at the genre, artist and album levels.  Is there a reason for the difference?

I have noticed that not all song tags are recognized by TagCache.  I have 70% AAC encoded files with the rest as MP3 format.  The AAC encoded file tags are not read consistantly.  Do others experience this?

Also, if I create my own entry ("80's" artist ? year ^ "198" : album ? year ^ "198" : title) I get an artist listing for every song that artist has.  For example, AH-HA has only one song (Take On Me) and shows up only once in the artist list, however U2 has over 200 songs on my ipod and is listed as many times in the artist screen.

Let me know if you need any more specific information.

Thanks for all the work!

AAC is not well supported yet, and our metadata parser for it has some issues. That's probably all of that, for now. When the support gets better, tagcache will read it better.

There's no NOT or OR operator. There's plans for them though.
It looks like you've got the rest of 'em right. They're not actually documented yet because they may change before it's "done".

As for your question about "levels" they aren't really levels. You just have cascading filters. One of them just has one filter, the second has several filters, which should decrease the results as you go down more levels. Basically, it shows results, and then you can see subfiltered results.

I _think_ the last thing you're describing is a known bug. If you filtered by the year 1985, and an artist had ONE song in 1985, for some reason when you picked that artist you'd see all songs by them. That's a bug in TagCache for the moment.

If I misunderstood something, let me know, and I'll attempt to clarify.

Llorean,

Thanks for your reply.  I think I can live with the AAC bugs for now since I don't feel like re-encoding all of my music again.  (However if I did, it would be in OGG...)

I'm not a coder, but if I can help in any way, troubleshooting or otherwise, let me know.

Thanks again,
John

So, is there any way to exclude something and don't display it ? I suppose without NOT fuction, the aswer is "no" but want to be shure....

Looks like this has been fixed (http://www.rockbox.org/viewcvs.cgi/apps/tagtree.c) in Rev 1.27 along with an OTF Playlist insert problem that I was experiencing and discussed in this thread:

Well, I could find no bug for that 'specifically', so I created one:

However, I also updated the similar 'genre bug' entry to say that it now appears to be fixed and could be closed out.

Hi!

I guess this thread is suitable for my question. The TagCache config file's syntax is way over my head. I've read the wiki entry many times, but I'm still too confused to create an useful layout.

I'm trying to make my layout to look like this:

Code: [Select]

Artist -> (Date) Album -> Tracknumber. Title

This layout is very similar to the default layout, expect for the date information. According to wiki entry, date tag is not available. But what is this 'year' filter then? I guess the wiki entry is outdated, right? So I don't even know where to start with creating this layout, if it's even possible to create. Any help is highly appreciated.

Regards,
Siku
