1. NAME

dome-key - Custom mappings for headphone buttons

2. SYNOPSIS

dome-key [options]

3. DESCRIPTION

Enables customisation of headphone buttons. The dome-key program runs in the background listening to button events, executing user-defined actions in response to these events.

Headphone button mappings are defined in a file called ~/.config/dome-key/mappings.dkmap. See MAPPINGS or dome-key-mappings(7) for more information.

4. OPTIONS

--audio: Play interface audio. Sounds will play to provide feedback when a mode is activated or deactivated.
-d, --daemon: Run the daemon in the current shell to listen for headphone button events. The program will run in the foreground.
-h, --help: Print usage help.
--license file: Register the software using the license plist file at path file.
-r, --reload-mappings: Reload the mappings file. If an instance of dome-key is running, no updates to the mappings file are taken into account automatically. Executing the program with this flag will cause the running daemon to reload the mappings file into its memory. This is typically easier than killing and relaunching the daemon.
-v, --version: Print the program version.

5. CONFIGURATION

An optional configuration file can be added at ~/.config/dome-key/config.toml.

Presently, only one configuration option is available. Here’s an example config:

timeout = 400

timeout: Sets the speed of multi-button mappings. To run an action mapped to <Play><Down>, you first press the ‘play’ button, then the ‘down’ button on your headphones. The time allowed between each button press is defined by this option. By default, it’s set to 500 milliseconds. It can be changed to any positive integer amount of milliseconds. Setting it to 0 will prevent multi-button mappings and cause button actions to be executed immediately.

6. MAPPINGS

Mappings are defined in ~/.config/dome-key/mappings.dkmap. See dome-key-mappings(7) for a complete explanation of the syntax.

If a button is not mapped, it retains its normal function. The following mappings apply when undefined, even without a mappings file:

map <Up> <VolumeUp>
map <Play> <Play>
map <Down> <VolumeDown>

7. LAUNCHD

It’s recommended that you run the program in the background using launchd(8). Here’s an example plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
        "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
        <key>Label</key>
        <string>com.teddywing.dome-key</string>
        <key>ProgramArguments</key>
        <array>
                <string>/usr/local/bin/dome-key</string>
                <string>--daemon</string>
                <string>--audio</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
        <key>KeepAlive</key>
        <true/>
        <key>StandardErrorPath</key>
        <string>/tmp/dome-key.log</string>
</dict>
</plist>

You can also use brew services to do this automatically if the program was installed with Homebrew.
