Support functions for auto-playlists & filters

[redwing]

I have requested this before, but can't find the thread.
Would be great if auto-playlists and filters support writing functions just as it supports writing regex. The difference is regex can't support fields. Say you want to create an auto-playlist that shows files having the same value for specific two tags. Currently you have to create a virtual tag first and then use that tag in an auto-playlist. Why not allow to define it directly in auto-playlists and filters?
This would also have the benefit to free up virtual tags from the limited 16 slots as the user could create an unlimited number of auto-playlists and filters.

i am not sure i understand this request. Could you give an example how you might enter such an expression

[redwing]

Basically the same as how "match Regex" works except "Any field" should be used.

Any field / match function / <Composer>
would show tracks that have a composer field value.

Any field / match function / <Title>=<Sort Title>
would show tracks that have the same value for the two fields.

Any field / match function / $Len(<URL)>200
would show tracks have the URL length longer than 200 ($Len is supported only with Additional Tagging Tools plugin installed).

Also support "does not match function" to negate the whole function easily.

i think this approach should do most of what you are asking for, but can you confirm i am right and that it will be useful?

field/ match template/ template eg. Artist/ match template/ $First(<Artist>)
field/ not-match template/ template

[redwing]

I think using "Any field" would be more useful and less confusing especially
- When multiple fields are listed in the template
- When fields are listed that are not available from auto-playlist drop-down menu

So when "(not) match template" is selected, "Any field" should be forced.

I am sorry redwing but i am not prepared to do this the way you have asked because its quite substantial as requested.
If you dont think the compromise i am proposing is going to work well, i will leave this request not implemented

[redwing]

I'm not sure why you think this request is so substantial as auto-DJ already works that way when a virtual tag is selected.
Whatever template is entered, just add tracks to the playlist that has a value for the template. Why is it so difficult?

[Steven]

I think i get what you are asking for now however i think the proposed implementation may be too obscure.
Also as far as I can tell there isnt really a need for a "not" template. The template can include a $If with and = or !=
I will sit on this for a while

Bump.
This could free up unlimited number of virtual tags from the limited 16 slots.
