Queueing Tracks

Tracks may be queued from the browser page using one of the views. Click on a track to append it to the queue.

An asterisk will be displayed next to tracks that have been queued by users. This feature originated at the Bitlair Hackerspace where tracks should not be skipped when they are queued by users.

The Queuer

If the queue runs out of tracks, Trollibox will pick a random track from the library and play it. The selection bias for tracks can be configured by setting one or more rules on the Queuer page.

Such rules consist of simple expressions that evaluate to a boolean value. A track must pass all rules set for it to be eligible for playing.

The equals and contains operations are case insensitive.

The matches operation takes a regular expression in Go's regexp format.

Streams

Trollibox has support for HTTP streams. You can create a custom collection using the Streams interface.

Searching

The search view allows you to search the whole library of the current player for tracks whose artist, title or album attributes contain some keywords.

Searching is case insensitive.

A track must match all keywords in order to end up in the results.

The search string is split on each space, unless you escape it with a backslash: foo\ bar.

You can annotate the keywords in your query to search other fields, You can limit a keyword to a single attribute by annotating them like this:

photographer genre:trance

The string photographer will be applied to the default attributes while the genre must match "trance".

Available attributes are:

• uri
• artist (default)
• title (default)
• genre
• album (default)
• albumartist
• albumtrack
• albumdisc

You can also use the duration attribute with relational operators to filter on whether a track's length is less, greater than or equal to some reference integer.

duration<120
duration>120
duration=120

Q & A

What does the asterisk next to queued tracks indicate?

See Queueing Tracks.

Where is the button to update the library?

There isn't. Trollibox is only a browser/player. Managing the files of the library is out of the scope of this project, which includes updating the player's database.

How do I add stuff to the library?

Using whatever options the player you are using is giving you. Trollibox is only a browser/player. You should manage your library in some other way.

I can't see the player on my phone.

The player is hidden on small screens to preserve space. The player is accessible on a separate view for such devices.
