Elisa is a music player developed by the KDE community that strives to be simple and nice to use. We also recognize that we need a flexible product to account for the different workflows and use-cases of our users. We focus on a very good integration with the Plasma desktop of the KDE community without compromising the support for other platforms (other Linux desktop environments, Windows and Android). We are creating a reliable product that is a joy to use and respects our users privacy. As such, we will prefer to support online services where users are in control of their data.
Elisa is still in heavy development and aims to implement the following goals:
- being easy to setup (ideally, one would not setup anything before being able to use it) ;
- being fully usable offline (or in privacy mode) ;
- being open to leverage online services but not a development priority (the experience should not be degraded when you are offline) ;
- being focused on satisfying users' goals ;
- being focused on music player (managing your music collection is not a development priority). This means that it is not a direct fulfilment for people needing that. This seems that a dedicated application would be more appropriate ;
- being as much as possible bug free (meaning stability has higher priority than feature development) ;
- targets Linux Plasma Workspace, other Linux desktop environments, Android and Windows ;
- being able to leverage UPnP DLNA.
The following snapshots show the current interface. They are only indicative and everything is open for improvements.
Elisa is loosely following design mockups made by the Visual Design Group of KDE. The mockups can be found here.
You can obtain Windows builds from https://binary-factory.kde.org/job/elisa-master-win32/
The Elisa team is open to any contributions and feedback.
Bugs can be reported to bugs.kde.org.
There is also a Elisa mailing list available for coordination.
Compilation from source
The way Elisa application is built is completely standard for an application based on Qt5, KDE Frameworks 5 and cmake:
Elisa has a few dependencies mainly from Qt5 and KF5 with the minimum required versions being Qt 5.10 and KDE Frameworks 5.45. Currently the list is:
* Qt5Network * Qt5Qml * Qt5Quick * Qt5Test * Qt5Sql * Qt5Multimedia * Qt5Svg * Qt5Gui * Qt5Widgets * Qt5QuickTest * Qt5 * ECM * Qt5Core * Gettext * PythonInterp * KF5I18n, KF5 text internationalization library. * KF5CoreAddons, Qt addon library with a collection of non-GUI utilities. * KF5FileMetaData, Provides a simple library for extracting metadata. * KF5Config, Persistent platform-independent application settings.
* KF5Declarative, Integration of QML and KDE work spaces. * KF5Baloo, Baloo provides file searching and indexing. * KF5XmlGui, Framework for managing menu and toolbar actions. * KF5ConfigWidgets, Widgets for configuration dialogs. * KF5KCMUtils, KF5 Utilities for KDE System Settings modules library. * KF5Package, KF5 package management library needed to get the configuration dialogs.
* Qt5DBus, Qt5 DBus is needed to provide MPris2 interface to allow remote control by the desktop workspace. * KF5DocTools, Create documentation from DocBook library. * KF5Crash, Graceful handling of application crashes. * KF5DBusAddons, Convenience classes for D-Bus. * UPNPQT, UPNP layer build with Qt 5., <https://gitlab.com/homeautomationqt/upnp-player-qt>
* Qt5QuickWidgets, Qt5 Quick Widgets is needed at runtime to provide the interface. * Qt5QuickControls2, Qt5 Quick Controls version 2 is needed at runtime to provide the interface. * Qt.labs.platform, Qt.labs module with some qml components wrapping platform APIs * qml-module-qtqml-models2, qml Qt module * qml-module-org-kde-kcm, qml module from KF5 KDeclarative framework * qml-module-qtquick-controls, qml Qt module * qml-module-qtquick-dialogs, qml Qt module * qml-module-qtquick-layouts, qml Qt module * qml-module-qtquick2, qml Qt module
For example on Debian and derivatives you may use:
apt-get install qtbase5-dev qtmultimedia5-dev qtdeclarative5-dev libqt5svg5-dev libkf5i18n-dev libkf5filemetadata-dev baloo-kf5-dev libkf5config-dev libkf5kcmutils-dev libkf5declarative-dev libkf5coreaddons-dev libkf5doctools-dev libkf5xmlgui-dev libkf5crash-dev libkf5dbusaddons-dev extra-cmake-modules gettext qml-module-qt-labs-platform qml-module-qtqml-models2 qml-module-org-kde-kcm qml-module-qtquick-controls qml-module-qtquick-dialogs qml-module-qtquick-layouts qml-module-qtquick2
The next state is to get Elisa sources and build them:
git clone https://anongit.kde.org/elisa.git cd elisa mkdir build cd build cmake .. make
You can execute it with the following command:
You may also now install Elisa system-wide, but beware that the following cannot always be undone (read the build instructions for more information). If you wish to do anyway, run
sudo make install
Windows is built using the Craft build system. Please follow instruction
in the Windows PowerShell to download and compile all required dependencies and Elisa itself.
Design Open Questions
The design of Elisa currently leaves open questions about the direction. At least the following points need an identified solution that could be implemented:
- Implement User Centered Design to help guide the development (definition of persona, ...) ;
- trying to combine an interface to be used with the mouse and with the touchscreen commonly found on laptops ;
- how to decide what is done with a single click, double click or single long click.
Description of the Application Architecture
Currently, music is retrieved from Baloo and put in an SQLite memory database. A local file indexer can be used in addition or when Baloo is not available.
The user interface is done in Qml with Qt Quick Controls 1 and 2. A port to Qt Quick Controls 2 only is slated for the future.
The UPnP support is probably broken right now.
