Creating custom Tagcache query?

[afruff23]

The tagnavi.config syntax is very confusing, even with that guide in the wiki. Any help is appreciated. Thanks.

Hi, I would like to create a tagcache menu item called "Electronica". I would like it to work by adding any songs tagged with house, trance, electronica, IDM, etc. (I have many other genres, but an example consisting of more than 2 genres under this menu item will help me do the rest on my own). The menu item should be called "Electronica" as stated before. The first level should display artists. The second level should display albums. The third level should display tracks.

Also, I would like to create another tagcache menu item called "Genre Albums". This would have the first level be genres. The second level would be albums. The third level should display tracks.

Thanks again.

The Wiki has not yet been updated with the V 2.0 syntax changes...

When I am having more time next month I was planning to update the wiki (unless someone beats me to it).

I think this should work, but I haven't tested it

Code: [Select]

"Electronica"  -> artist ? genre = "house" & genre = "trance" & genre = "IDM" -> album -> title = "%02d %s" tracknum title

This will work:

"Genre Albums"        -> genre -> album -> title = "%02d %s" tracknum title

However the | (OR) operator has not been implemented (yet). Unfortunatly this is not easy to do either.

For your special case I can envision a "oneof" operator, where you supply a list of possible values e.g.

Code: [Select]

"Electronica"  -> artist ? genre oneof "house|trance|IDM" -> album -> title = "%02d %s" tracknum title

I might give it a try and make a patch to see how well it works.

Unfortunately this won't work.

Of course it won't, I was forgetting my database queries logic there  Thanks for putting me straight. Oh well, one out of two isn't too bad.

Please do. =)

[roolku]

Please do. =)

Okay, I have made a start. I think everything is covered, but it could probably do with some clarification and examples. If you find any errors please let me know (or fix them on the wiki)

Cheers

Thanks for that roolku, it looks pretty comprehensive to me.

Thank you for updating the wiki. It's a bit clearer now. An "or" or "oneof" operator would be great.

A pleasure.

Thank you! Do you think this will ever get into CVS builds?

So what's all this then...?

...followed by a heading (in quotes). The heading is displayed if the option is enabled in the settings...

I wondered why the menu name was mentioned twice, but I can find no such setting in the menus or a freshly-created .cfg file.

Is this done via some mysterious other config file?

I'd really like to be be able to have a title/heading for  the Tag Cache menus.

Your guess is as good as mine.
As far as I can see I haven't violated any quidelines, so it is just a case of a developer (Slasheri?) knowing about and liking it.

General Settings/File View/Show Path

Not the most obvious setting I suppose...

No, it's not, but it works a treat... thanks!
I had always assumed that Show Path was just for the File Browser, not Tag Cache.

I just got the email that it has been accepted.

better go and update the wiki...

[afruff23]

Thank you so much!

However, I seem to be having a prolem. I did not edit the tagnavi.config file. The changes are all in tagnavi_custom.config

This line:

Code: [Select]

"Electronica Artists" -> artist ? genre @ "Ambient|Big Beat|Breakbeat|Breaks|Electronic|House|IDM|Psychedelic|Rave|Techno|Trance|Electronica|Synthpop" -> album -> title = "%02d. %s" tracknum title

does not work. Instead, it displays ALL artists(not excluding any). Whenever you select an artist, the cursor moves back to the top of the list.

This does work however:

Code: [Select]

"A" -> artist ? genre @ "Progressive Rock|Trance" -> album -> title = "%02d. %s" tracknum title

There are no extraneous spaces or end of lines in case you are wondering.
