Move audio ownership out of the shared runner and into each style via an
injected Sound capability (play_music(path) / play_beep()). The runner now
only owns button sampling and cleanup; the style kicks off its own tone in
start() and drives the LED.
- simple: a repeating square-wave beep (ordinary alarm-clock tone), no music
file required. The beep is synthesised in memory as signed-16-bit stereo
PCM (stdlib array+math) and played via pygame.mixer.Sound — no shipped
audio asset, no new dependency.
- blink: unchanged behaviour — music on an endless loop from --music-file /
MUSIC_FILE / the default track, via pygame.mixer.music.
- AlarmStyle contract gains sound + music_file in __init__ and a start()
lifecycle hook; AlarmSound Protocol documents the audio seam for future
styles that handle their own tone.
- setup() no longer loads music (that is the style's job now).
README updated: per-style ringing tone, the --music-file note (blink only),
and the extended plugin contract.
Nothing imports AlarmStyle via the styles namespace (blink/simple both
import from styles.base directly), so the redundant-alias re-export was
dead weight that only existed to silence ruff F401.
Add an Alarm Styles section (simple vs blink), show --style in manual usage,
and update the GraphQL examples (setAlarm/getAlarms/startRinging) to include
the style field/argument. Note backward compat for legacy cron entries.
- crontab_manager.get_alarms now parses --style from the cron command
(defaults to 'blink' for legacy entries without --style)
- GraphQL Alarm type gains a 'style' field
- setAlarm accepts a 'style' arg (default 'simple') and validates it
against the styles registry; unknown styles raise a GraphQL error
- _default_command embeds --style <name> into the cron command
- startRinging accepts 'style' (default 'simple') and passes --style to
the spawned wecker.py
The crontab remains the single source of truth; the style simply rides
in the cron command alongside --music-file.
Introduce a styles/ plugin package:
- styles/base.py: AlarmStyle ABC (injected set_led, update()->bool contract)
- styles/blink.py: BlinkStyle, the existing count-the-blinks puzzle moved
out of wecker.py's AlarmClock
- styles/simple.py: SimpleStyle, press-once-to-stop (the new default style)
- styles/__init__.py: STYLES registry + get_style() validator + LEGACY_STYLE
wecker.py now resolves the style via the registry and owns only the shared
music/button/cleanup loop; the --style CLI arg defaults to blink so existing
cron entries keep their behaviour. Unknown styles raise before hardware init.
