Non-GUI program, which allows one to run QML project in the background.

Currently only Linux is supported.

Use --project command line option to specify the QML project file to open. For example to run CountDaemon example use following command.

cutehmi.daemon.1 --project="examples/cutehmi.daemon.1/CountDaemon/Main.qml"

Fore debug builds use cutehmi.daemon.1.debug instead of cutehmi.daemon.1. Read system logs to investigate whether daemon is running (e.g. journalctl -n20 on a system with systemd).

One may use --app option to tell the program to work as a foreground process (this can be useful when testing projects).

cutehmi.daemon.1 --project="examples/cutehmi.daemon.1/CountDaemon/Main.qml" --app

Running this example should result in printing following lines.

qml: Hello from counting daemon!
qml: I can count to 1
qml: I can count to 2
qml: I can count to 3
qml: I can count to 4
qml: I can count to 5
qml: I can count to 6
qml: I can count to 7
qml: I can count to 8
qml: I can count to 9
qml: I can count to 10

You can use --help command line argument to see the list of all possible command line options.

Signals

Under Unix daemon will respond to signals in a following way.

SIGTERM tells daemon to gracefully quit with exit code set to EXIT_SUCCESS (0 on almost all systems).
SIGINT tells daemon to gracefully quit, but exit code will be set to 128 + signal code.
SIGQUIT causes violent termination and exits via abort.
SIGHUP attempts to reload the project as if daemon has been restarted.
