forked-daapd smart playlists

To add a smart playlist to forked-daapd, create a new text file with a filename ending with .smartpl; the filename doesn't matter, only the .smartpl ending does. The file must be placed somewhere in your library folder.

Syntax

The contents of a smart playlist must follow the syntax:

"Playlist Name" { expression }

There is exactly one smart playlist allowed for a .smartpl file.

An expression consists of:

field-name operator operand

Where valid field-names (with their types) are:

• artist (string)
• album_artist (string)
• album (string)
• title (string)
• genre (string)
• composer (string)
• path (string)
• type (string)
• grouping (string)
• data_kind (enumeration)
• media_kind (enumeration)
• play_count (integer)
• rating (integer)
• year (integer)
• compilation (integer)
• time_added (date)
• time_modified (date)
• time_played (date)

Valid operators include:

• is, includes, starts with (string)

• , <, <=, >=, = (int)

• after, before (date)
• is (enumeration)

The "is" operator must exactly match the field value, while the "includes" operator matches a substring. The "starts with" operator matches, if the value starts with the given prefix. All three matches are case-insensitive.

Valid operands include:

• "string value" (string)
• integer (int)

Valid operands for the enumeration "data_kind" are:

• file
• url
• spotify
• pipe

Valid operands for the enumeration "media_kind" are:

• music
• movie
• podcast
• audiobook
• tvshow

Multiple expressions can be anded or ored together, using the keywords OR and AND. The unary not operator is also supported using the keyword NOT.

Examples:

"techno" {
   genre includes "techno"
   and artist includes "zombie"
}

This would match songs by "Rob Zombie" or "White Zombie", as well as those with a genre of "Techno-Industrial" or "Trance/Techno", for example.

"techno 2015" {
   genre includes "techno"
   and artist includes "zombie"
   and not genre includes "industrial"
}

This would exclude e. g. songs with the genre "Techno-Industrial".

"Local music" {
  data_kind is file
  and media_kind is music
}

This would match all songs added as files to the library that are not placed under the folders for podcasts, audiobooks.

"Unplayed podcasts and audiobooks" {
  play_count = 0
  and (media_kind is podcast or media_kind is audiobook)
}

This would match any podcast and audiobook file that was never played with forked-daapd.

Date operand syntax

One example of a valid date is a date in yyyy-mm-dd format:

"Files added after January 1, 2004" {
  time_added after 2004-01-01
}

There are also some special date keywords:

• "today", "yesterday", "last week", "last month", "last year"

A valid date can also be made by applying an interval to a date. Intervals can be defined as "days", "weeks", "months", "years". As an example, a valid date might be:

3 weeks before today or 3 weeks ago

Examples:

"Recently Added" {
    time_added after 2 weeks ago
}

This matches all songs added in the last 2 weeks.

"Recently played audiobooks" {
    time_played after last week
    and media_kind is audiobook
}

This matches all audiobooks played in the last week.

Differences to mt-daapd smart playlists

The syntax is really close to the mt-daapd smart playlist syntax (see http://sourceforge.net/p/mt-daapd/code/HEAD/tree/tags/release-0.2.4.2/contrib/mt-daapd.playlist).

Even this documentation is based on the file linked above.

Some differences are:

• only one smart playlist per file
• the not operator must be placed before an expression and not before the operator
• "||", "&&", "!" are not supported (use "or", "and", "not")
• comments are not supported
