媒体控制器

media-controller 提供一个始终位于顶部的具有透明度支持的 GTK-3 窗口，在相应地更改后立即显示当前的音量/亮度。

它使用 UNIX 套接字，因此如果在第一个实例运行时创建了另一个实例，它不会创建另一个窗口，而是简单地更新另一个实例的值，从而提供平滑的体验。

为了在您的系统上运行它，只需创建一个新的 cargo 项目。添加库

cargo add media-controller

然后只需实现一些函数。您的 main.rs 应该看起来像这样

/// Should toggle mute.
fn toggle_mute() {
    todo!();
}
/// Should return whether it's muted.
fn get_mute() -> bool {
    todo!();
}
/// Should return the volume (0-100).
fn get_volume() -> u8 {
    todo!();
}
/// Should return the brightness (0-100).
fn get_brightness() -> u8 {
    todo!();
}
/// Should increment the volume. To decrement use a negative value.
fn inc_volume(value: i8) {
    todo!();
}
/// Should increment the brightness. To decrement use a negative value.
fn inc_brightness(value: i8) {
    todo!();
}
fn main() {
    /// Pass `Some` to use custom options.
    /// Pass `None` to manage them through command line arguments.
    let custom_controller = None;

    controller::MediaControllerApp {
        toggle_mute,
        get_mute,
        get_volume,
        get_brightness,
        inc_volume,
        inc_brightness,
        custom_controller,
    }
    .run();
}

一个具体的例子可以在 src/main.rs 中找到，这是一个使用 wpctl 和 brightnessctl 的 Linux 系统的示例。

将 media-controller 映射到媒体键特别有用。使用 sxhkd，它应该看起来像这样

# Volume Control
XF86AudioLowerVolume
  media-controller v down 5
XF86AudioRaiseVolume
  media-controller v up 5
XF86AudioMute
  media-controller v mute

# Brightness Control
XF86MonBrightnessDown
  media-controller b down 5
XF86MonBrightnessUp
  media-controller b up 5
