alarm clock plugin for DeaDBeeF
This plugin allows the DeaDBeeF music player to serve as an alarm clock.
Even with its comprehensive set of command-line options, DeaDBeeF is
ultimately a graphical program, in most cases completely unreachable
from the restricted environment in which crontab shell scripts are executed.
The MPRIS plugin does allow some control of the media player from a crontab
script, but because a script executed by cron usually cannot find the dbus session bus
address in its environment, this variable must be hard-coded in the
shell script you intend to use for activating DeaDBeeF. (For a clumsy way to
automate the hard-coding of session bus address, you might add some sed commands
to your window manager's autostart script, overwriting a definition line in the
activate-DeaDBeeF script.) Then having surmounting this
obstacle, you'll discover that the MPRIS plugin implements only one method for
selecting a particular file for playback: OpenUri. Even if xdg-mime could be
persuaded that the file extension m3u indicates a filetype audio/x-mpegurl rather
than text/plain (so that the OpenUri argument is not immediately rejected upon
receipt of the dbus message), the MPRIS plugin only implements OpenUri using
deadbeef->plt_add_file2, while a playlist would require
deadbeef->plt_load2. So to assemble an entire playlist using the methods available
in the MPRIS plugin, you would have to parse the metadata of each song to determine
how long the parent process should sleep between successive calls of OpenUri.
TLDR: working around the limitations of crontab and MPRIS is more trouble than building a specialized plugin for alarm clock functionality.
To close the gap between DeaDBeeF and its console-interface counterparts (moc, mpd, cmus -- all of which can be controlled by scripts in a crontab), this plugin translates the essential components of the audacious alarm plugin into the DeaDBeeF idiom. The configuration dialog lets you choose which days of the week the alarm goes off, what time of day, and which playlist you want loaded. Leaving the playlist field empty (or selecting an invalid file) will just start playback at the beginning of the current list when the alarm goes off.
What is missing
The following features were present in the audacious alarm plugin, but have not been implemented here.
- Volume fading from quiet to loud after a fixed time interval. If you need that kind of control, all the underlying audio stacks (ALSA, OSS, Pipewire, Pulseaudio, sndio) offer command-line mixer tools that work fine when executed within crontab scripts, and you can just leave the DeaDBeeF volume slider at its highest level.
- Stopping the playback after a specified time interval. (TODO: let the plugin itself turn off repeat mode if that behaviour is desired, simply by adding a "disable repeat mode" checkbox to the alarm configuration dialog. It then becomes the user's responsibility to make sure a playlist of the appropriate length is selected, so playback doesn't continue past the transition from sleep to wakefulness.)
- Setting a different alarm time for each day of the week. Sleep professionals recommend that you stick to a consistent bedtime and wakeup time for optimal health. (But if you have a healthy sleep regimen in the first place, you probably wake up at the right time without an alarm. Omitting this feature thus makes the plugin less useful to people who genuinely need a mechanical disruption of their established sleep-wake cycle.)
How to install
For CRUX users
- cd to a directory in your local ports overlay
- download the source code from this host:
httpup sync https://git.sdf.org/jmq/cruxports/raw/branch/master/#deadbeef-alarm deadbeef-alarm
- prt-get depinst install deadbeef-alarm
For users of other Linux distributions
- check that all dependencies and header files are installed (DeaDBeeF and glib)
- save the source code and the Makefile
https://git.sdf.org/jmq/cruxports/deadbeef-alarm/Makefile) into a working directory.
- cd to the working directory and run make. Invoke make with
GLIB_CXX_FLAGS="$(pkg-config --cflags glib-2.0)"and
GLIB_LD_FLAGS="$(pkg-config --libs glib-2.0)"if your distribution has installed the shared glib libraries in non-standard locations.
make install, optionally prepending a custom setting for PREFIX (such as $HOME/.local) or DESTDIR.
