See https://apps.kde.org/elisa/
 
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.
 
== Goals ==
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.

Elisa is loosely following design mockups made by the Visual Design Group of KDE. The mockups can be found [https://community.kde.org/KDE_Visual_Design_Group/Music_Player here].
 
== Try It ==
 
Some packages already exist. [https://community.kde.org/Guidelines_and_HOWTOs/Flatpak Flatpaks] for Elisa are available. There is an AUR and it is packaged for KDE neon Developer Unstable. The releases are  usually packaged for [https://copr.fedorainfracloud.org/coprs/eclipseo/elisa/ Fedora]
 
You can obtain Windows builds from https://binary-factory.kde.org/job/elisa-master-win32/
 
== Get Involved ==
 
The Elisa team is open to any contributions and feedback.
 
Bugs can be reported to [https://bugs.kde.org/ bugs.kde.org].
 
Development can be followed on [https://phabricator.kde.org/tag/elisa/ Elisa tasks board].
Code contributions have to be submitted via [https://invent.kde.org/kde/elisa Gitlab]. You can follow generic user instruction for Gitlab and a merge request workflow.
 
We are in a transition from Phabricator to Gitlab. During the transitions, merge requests have to be sent via Gitlab when tasks are still handled by Phabricator.
 
There is also a [https://mail.kde.org/mailman/listinfo/elisa Elisa mailing list] available for coordination.
 
== Compilation from source ==
=== on Linux ===
The way Elisa application is built is completely standard for an application based on Qt5, KDE Frameworks 5 and cmake.
 
; [[Get Involved/development#Applications]]

For example on Debian and derivatives you may use:
 
sudo apt 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:
 
./elisa/build/bin/elisa
 
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
 
=== on Android ===
 
It is now possible to build a very simple application based on Elisa on Android.
 
cmake .. -G Ninja -DCMAKE_SYSTEM_VERSION=19 -DCMAKE_INSTALL_PREFIX=<workspace>/androidRoot -DCMAKE_ANDROID_NDK=<workspace>/Android/Sdk/ndk-bundle -DCMAKE_TOOLCHAIN_FILE=<workspace>/androidRoot/share/ECM/toolchain/Android.cmake -DECM_ADDITIONAL_FIND_ROOT_PATH="<workspace>/Qt/5.11.1/android_armv7;<workspace>/androidRoot;<workspace>/Android/Sdk/ndk-bundle/platforms/android-19/arch-arm/usr/lib" -DKF5_HOST_TOOLING=/usr/lib/x86_64-linux-gnu/cmake -DQTANDROID_EXPORTED_TARGET=elisa -DANDROID_APK_DIR=../data
 
=== on Windows ===
 
Windows is built using the Craft build system. Please follow instruction
 
; [[Craft#Setting_up_Craft| Setting up of Craft]]
 
and enter
 
craft elisa
 
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 2.
 
The UPnP support is probably broken right now.
