Amarok Blog

First of all, just to get the terminology straight. In this post, I define a filter as something that limits what you actually see in a view, and a search as something that selects items in the view without affecting other elements.

Amarok 1 style playlist filtering.

Since Amarok 2.0.0 was released, one of the frequently mentioned Most Missed Features (MMF) is the Amarok 1.4.x style playlist filtering.

The filtering in Amarok 1.4.x is indeed very powerful, but it also suffers from a number of usability problems and is actually sort of a weirdly placed feature as the collection is where advanced filtering is meant to take place as it will always haver more powerful mechanisms for advanced filtering.

That said, we are very aware that there needs to be a simple way of locating content in large playlists and perhaps even limit the playback of tracks to a subset of what is in the playlist in a non destructive way. Inspired by the progressive searching in apps like Firefox (and indeed many of the KDE 4 applications) we decided to try this out instead. So, hidden away in a small cabin in the very dark woods, far away from streetlights and traffic, I decided to have a go at this.

Amarok 2 style playlist searching.

This morning I committed the initial version of a rather advanced playlist search feature. At its very core, it is just a progressive, as you type, search. This means that as you type, the first track that match the current search term will be selected (and the playlist scrolls to it). Next and previous buttons then allows you to jump around in the tracks matching the search (These really need to get some keyboard shortcuts... Working on that one). The search edit gives immediate feedback on whether there are any matches or not, in the same way that, for instance, the KDE 4 version of Konsole does. By turning the search edit a different color and disabling the next and previous buttons. Now by itself, this is useful, but not super powerful, but this playlist search has a few additional tricks up its sleeve. It is possible to specify which fields should be matched against when typing a query. This is changed by clicking off the fields in a small drop down menu.

Currently it is possible to search any combination of track name, album name, artist name, genre name, composer name or year, and I have a few more ideas for properties to search that i am going to add. It is also possible to "lock" the track progression to only play tracks that matches the current search term. This is toggled using the same small drop down menu. It provides a very convenient way of just playing a particular artist from your all time favorites playlist or any number of similar use cases. Currently this only works when using "standard" or "random track" playback modes however, and I am still pondering whether it actually makes sense for any of the other progressions modes, such as "random album". All the options from this drop down menu are of course stored in the config so the options are persistent across sessions.

We are aware that some people will still miss the old style filtering and that this is not the same thing. We do believe however that a search makes more sense in the playlist than a filter, and that this satisfies many, although not all, of the use cases that the old filter did. Going forward, it might also be possible to add other features to the search, such as selecting all matching tracks, or exporting matches to a new playlist, if there are use cases that support these additions.

One thing I am still pondering is if the filter bar should be visible at all times, making the feature very easily discoverable, or if it should only appear when the search keyboard shortcut is activated....

As mentioned, I committed this code this morning, and baring any major issues turning up, it will be appearing in Amarok 2.0.1 which should be released shortly after new year if all goes well. If you cannot wait that long, it should be appearing in the nightly builds shortly, and failing that, there is always building straight from svn!
