Briar Desktop
A desktop program for Briar, bringing secure messaging to your desktop and mobile devices.
Note that Briar Desktop is still in a very early prototype stage and not yet functional.
Installation
We plan to distribute Briar for Debian (and related distributions) as .deb and via Flathub.org as flatpak, but until now, there are only semi-official installation methods available. You might want to use them now for not having to wait, but please note that those installation methods will be deprecated once Briar is available for Debian and on Flathub.org.
Self-contained Java .jar
The simplest way is to download the nightly briar-desktop.jar and execute it from the command-line with java -jar briar-desktop.jar
. Note that you need at least version 11 of the Java Runtime Environment.
Self-contained .deb
For Debian- and Ubuntu-based Linux distributions, a set of .deb files is available. Depending on which version of Debian/Ubuntu your OS is based on, you can choose the right .deb file:
Here are some examples of popular distributions and their respective .deb file:
- Ubuntu 20.04 and compatible: Linux Mint 20.X (Ulyana, Ulyssa, Uma, Una), elementaryOS 6.X (Odin, Jólnir), Trisquel 10 (Nabia)
- Debian stable (bullseye) and compatible: MX Linux MX-21
- Ubuntu 18.04 and compatible: Linux Mint 19.X (Tara, Tessa, Tina, Tricia), elementaryOS 5.X (Juno, Hera), Trisquel 9 (Etiona)
Developers
Download Source Code
Briar dependencies are included as Git Submodules. To be able to build Briar Desktop, download the source code and the submodules using
git clone --recurse-submodules [email protected]:briar/briar-desktop.git
or
git clone --recurse-submodules https://code.briarproject.org/briar/briar-desktop.git
Intellij IDEA
The easiest and most convenient way to build Briar Desktop is by using Intellij IDEA.
UI Previews
Briar Desktop makes use of Compose for Desktop to build its UI. The Intellij IDEA plugin Compose Multiplatform IDE Support provides static previews of composable functions without parameters which are annotated with @Preview
.
Building and Running
In order to build and run the application from the command line, execute this:
./gradlew run
You can specify arguments to the app using the --args
option of the Gradle task. For example to show the usage info:
./gradlew run --args="--help"
To specify a different data directory and enable the debug output:
./gradlew run --args="--debug --data-dir=/tmp/briar-tmp"
In case you want to build a self-contained Debian package, note that you need at least JDK 17 and that you might need to install binutils
and fakeroot
before running the respective task:
./gradlew packageDeb
If you want to use the JDKs downloaded by Intellij IDEA, you can for example specify the path like this:
./gradlew packageDeb -Dorg.gradle.java.home=$HOME/.jdks/openjdk-17.0.2
Take a look at .gitlab-ci.yml if you have problems with Kotlin and JDK 17.
Translations
See TRANSLATION.md for more information.
Hacking
See HACKING.md for useful information when trying to work with the source code.
Maintenance
From time to time, translations and Flatpak's dependencies should be updated. The former can be done with tools/update-translations.sh
, the latter using flatpak-builder-tools.
Design Goals
- Intuitive UI, similar to Briar Android client
- Main platform is GNU/Linux, but also support (at least) Windows and macOS
- Analogously, main platform is x86, but also support (at least) arm
- Adaptive to different screen sizes (desktop and mobile devices)
- Has phone constraints in mind
FAQ
How can I delete my account?
