Automatický tvůrce seznamu skladeb
Automatický tvůrce seznamu skladeb automaticky tvoří seznamy skladeb založené na vámi nastavených omezeních. Tato omezení mohou být nastavena podle dat písně (umělec, žánr, rok) nebo času přístupu (naposledy hráno). Jsou i zvláštní omezení, která určují, jak způsobem Amarok bude hledat písně. Automatického tvůrce seznamu skladeb najdete v poli s hudebními zdroji, .

Removes the selected preset from the list; can not be undone.
Import a preset from a .xml file. Has the potential to be malformed if edited outside Amarok; use the constraint tester.
Export the selected preset to a .xml file that can be imported.
Loads APG with the selected preset and automatically generates a playlist.
Práce s přednastaveními
Presets are sets of rules that Amarok APG will use when generating playlists. These rules are going to be referred to as constraints from now on; every preset is determined by the constraints which create it. Groups of constraints hierarchically and logically organized are called constraint trees.
Omezení
Constraints are the building blocks of constraint trees. They are simple statements that the APG will use to add songs to the playlist it generates. To add a constraint to the currently selected preset constraint tree click the button in the APG Preset toolbar and click the option on the APG Preset Editor window. Note that this will add the constraint under the selected item (constraint or constraint group).
Many different kinds of constraints can be added; each works in a different way inside the tree.
Typy omezení
APG Amaroku podporuje několik typů omezení:
| Omezení | Popis |
|---|---|
| The most important constraints, because they can be set to virtually any information regarding the file, including: artist name, album name, genre, year, last played, and score. | |
| Set the running time (in HH:MM:SS format) that the playlist should have | |
| Determine how many songs should be in the playlist | |
| Tell Amarok where to start and stop looking for tracks | |
| Prevent Amarok from selecting the same tracks, songs from the same artist, or the same album |
Note that you can change how constraints work in various manners, such as setting the fuzzy-exact slider, which determines how closely the constraint is going to be followed.
Another way to modify constraints that is present on with a textbased tag is found in the line below the option box. In the text field to the right you write the text to be matched and in the option box at the left of the value you can select (which will consider any songs that have the according text in their tag), (which will consider songs whose corresponding tag match exactly the one in the text box), and .
Similarly, you can also edit the way value-based constraints (such as the constraints and the playcount constraint) behave by changing the option close to the text to settings such as , and .
Another way to change constraint behavior is to check the checkbox on them, this makes them behave the opposite way, a "Match Tag: artist contains name" becomes "Match Tag: artist not contains name".
Skupiny omezení
Constraint groups can be added from the option from the APG Preset Editor window, constraints under a group are logically linked, the same applies to groups under groups. There are currently two kinds of constraint groups: "Match all" groups and "Match any" groups. "Match all" groups require that all the constraints under them are met by the song. "Match any" groups require that at least one of the constraints under them are met by the song. To add a constraint under a specific group highlight it on the preset editor and use the option.
Používání vašich přednastavení
Once you set up a preset, you just have to select it on the APG Presets panel in the Automated Playlist Generator (APG) and click the toolbar to run APG with the selected preset. You will then have a playlist matching your criteria, like this:
