## Installation

1. install dependencies

Note that it requires [libcava](https://github.com/LukashonakV/cava), a fork of cava, which provides cava as a shared library.

:::code-group

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

2. clone repo

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

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
```
