Title: Help with expression for organising albums
Post by: Mr James Dunn on August 26, 2013, 05:35:39 am

Hi,

Some of my albums are multiple discs and the discs have titles rather than disc numbers. I have set up a custom [Disc Title] field and I'm trying to write an expression so that i can rename my files to create a folder (after [Artist]\[Album]..) using the [disc title] if there is one, the [disc #] if there isn't a title, or if there isn't either (for single disc albums) just the [track #] and [name] without creating a separate folder.

e.g.

Biffy Clyro\Opposites\The Land at the end of our toes\01- Different People.flac

or,

Led Zepplin\Physical Graffiti\Disc 2\01- In the Light.flac

or,

Audioslave\Out of Exile\01 - Your time has come.flac

I'm currently working with the If(IsEmpty()) expression but can seem to get it to works, can anyone work this out for me?

Cheers

James

Use this:

  FirstNotEmpty (http://wiki.jriver.com/index.php/Media_Center_expression_language#FirstNotEmpty)([Disc Title], [Disc #])

So your complete path under your media base path might be:

   [Album Artist (auto)\[Album]\delimit(FirstNotEmpty([Disc Title], [Disc #]),\)\[Track #] - [Name]

See:

Mr C,

I've just tried it on some files and where there is a [Disc Title] it works fine, but where there isn't it shows the name as [Album Artist (Auto)]\[album]\Unknown Disc Title\[Track #] - [Name].flac, it doesn't reference the [disc #] when there is one and still shows the same when there is neither a [disc title] or ]disc #].

Ive checked the spellings etc and they all seem OK. Could be something in my custom field set up that causes the problem?

Cheers

James

In some places, such as the Rename tool, you'll need to use a field's raw format:

  FirstNotEmpty([Disc Title,0], [Disc #,0])

You can probably just use that in all situations for your needs.

Search both Rename and raw here for more explanation:

Perfect!!

Thanks.

I do try to follow work out the expressions myself, but the 'logic' ends up making my head hurt!!
