_Warning: This is still in a very early state and should be considered as prototype._

A simple GTK app for [Briar](https://briar.app), built with Python and GNOME Builder.
It uses [python-briar-wrapper](https://code.briarproject.org/briar/python-briar-wrapper) and the
[Briar REST API](https://code.briarproject.org/briar/briar/blob/master/briar-headless/README.md)
and therefore requires Java.

## Installation

So far, there is no official installation method and
you have to build it from source.

## Developers

The easiest and most convenient way is to build _briar-gtk_ using
[Builder](https://wiki.gnome.org/Apps/Builder).
In _Builder_, click "Clone Repository" at the bottom and
enter the URL to this Git project.

You can also call this:
```bash
flatpak remote-add --user --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
flatpak-builder builddir --install-deps-from=flathub --user --install --force-clean --ccache app.briar.gtk.json
flatpak run app.briar.gtk
```

Additionally, you are able to run Briar GTK without Flatpak.
For this, you have to install Java, the
[Python dependencies](requirements.txt) and
[Briar headless](https://code.briarproject.org/briar/briar/blob/master/briar-headless/README.md).
Once you've done this, change the path of the Briar headless
jar in [src/briar/gtk/define.py](src/briar/gtk/define.py),
build it with _meson_ and start Briar GTK.

Don't forget to initialize the briar-wrapper submodule:
`git submodule update --init`

## Design Goals

* Intuitive UI, similar to Briar Android client
* Main platform is GNU/Linux, but should also support (at least) Windows and macOS
* Analogously, main platform is x86, but should also support (at least) arm
* Follows [GNOME Human Interface Guidelines](https://developer.gnome.org/hig/stable/)
* Adaptive to different screen sizes (desktop and mobile devices)
* Has [phone constraints](https://developer.puri.sm/Librem5/Apps/Guides/Design/Constraints.html) in mind
* Strictly separates API wrapper from GTK stuff, making former a solid base for other (commandline) clients

## FAQ

### How can I run this on the Librem 5?

Whether you own a Librem 5 or
[set up an emulator](https://developer.puri.sm/Librem5/Development_Environment/Boards/emulators.html),
you can install Briar GTK easily using Flatpak.

Before you start, you have to install some dependencies:

```bash
sudo apt install flatpak-builder elfutils
```

You can then simply
[follow the instructions from above](#developers).
Note that you currently don't get beyond the setup screen
because Briar Headless only works on x86 platforms so far.
