# Bluetooth

Library for monitoring [bluez](https://www.bluez.org/) over dbus.

## Installation

1. install dependencies

:::code-group

```sh [<i class="devicon-archlinux-plain"></i> Arch]
sudo pacman -Syu meson vala gobject-introspection
```

```sh [<i class="devicon-fedora-plain"></i> Fedora]
sudo dnf install meson gcc valac gobject-introspection-devel
```

```sh [<i class="devicon-ubuntu-plain"></i> Ubuntu]
sudo apt install meson valac gobject-introspection
```

:::

::: info
Although bluez is not a direct build dependency,
it should be self-explanatory that the daemon is required to be available at runtime.

2. clone repo

```sh
git clone https://github.com/aylur/astal.git
cd astal/lib/bluetooth
```

3. install

```sh
meson setup build
meson install -C build
```

:::tip
Most distros recommend manual installs in `/usr/local`,
which is what `meson` defaults to. If you want to install to `/usr`
instead which most package managers do, set the `prefix` option:

```sh
meson setup --prefix /usr build
```
