# 6.9.实用工具

一款有用的 Wayland 工具是 waybar，所有合成器都可以使用它。虽然 Wayfire 自带了启动菜单，但易于使用且快速的任务栏是所有合成器或桌面管理器的好配件。waybar 是一款与 Wayland 兼容的任务栏，快速且易于配置。要安装这个软件包以及一款支持的音频控制工具，可以执行以下命令：

```sh
# pkg install pavucontrol waybar
```

要创建配置目录并复制默认的配置文件，可以执行以下命令：

```sh
% mkdir ~/.config/waybar
% cp /usr/local/etc/xdg/waybar/config ~/.config/waybar
```

`lavalauncher` 工具提供了一个启动条，用于启动各种应用程序。该软件包没有提供示例配置文件，因此需要执行以下操作：

```sh
mkdir ~/.config/lavalauncher
```

以下是一个示例配置文件，它仅包含 Firefox，并将其放置在右侧：

```ini
global-settings {
	watch-config-file = true;
}

bar {
	output            = eDP-1;
	position          = bottom;
	background-colour = "#202020";

	# 默认配置集的条件。
	condition-resolution = wider-than-high;

	config {
		position = right;
	}

	button {
		image-path          =     /usr/local/lib/firefox/browser/chrome/icons/default/default48.png;
		command[mouse-left] =     /usr/local/bin/firefox;
	}
	button {
	  image-path           =   /usr/local/share/pixmaps/thunderbird.png;
	  command[mouse-left]  =   /usr/local/bin/thunderbird;
}
```
