Distributed Notification Names

[FelixKratz]

Lets collectively create a list of NSDistributedNotificationCenter
notifications we can hook onto via the event system. Please comment any you
come across and I will update the list in this post:

	Description
AppleInterfaceThemeChangedNotification	The system theme changes between light and dark mode
AppleInterfaceMenuBarHidingChangedNotification	The auto-hide menu bar setting is changed
AppleSelectedInputSourcesChangedNotification	The keyboard input source changes
com.apple.bluetooth.status	A bluetooth device is connected/disconnected
com.apple.screenIsLocked	The screen is locked
com.apple.screenIsUnlocked	The screen is unlocked
com.apple.HIToolbox.beginMenuTrackingNotification	The mouse begins tracking a menu, e.g. if a menu bar item is clicked
com.apple.HIToolbox.endMenuTrackingNotification	The mouse ends tracking a menu, e.g. if a menu bar item is clicked
com.apple.sharedfilelist.change	A new file is included in the shared file list
com.apple.DownloadFileFinished	A download has finished
com.apple.unmountassistant.process.start	A hard drive is about to get mounted
com.apple.LaunchServices.applicationRegistered	A new application is registered for the auto start

I found this handy link that lists a lot of NSNotificationNames that may or may not work with the eventing system.

NSCalendarDayChangedNotification looks useful for simple calendar scripting. Will do some testing!

Bluetooth:

• Device changed: com.apple.bluetooth.status
• Bluetooth on: IOBluetoothHostControllerPoweredOnNotification
• Bluetooth off: IOBluetoothHostControllerPoweredOffNotification

Example:

bluetooth=(
  icon.font="$FONT_FACE:Regular:19.0"
  label.padding_left=0
  label.padding_right=0
  script="$PLUGIN_DIR/bluetooth.sh"
)

...

  --add item bluetooth right \
    --add event bluetooth_status "com.apple.bluetooth.status" \
    --add event bluetooth_on "IOBluetoothHostControllerPoweredOnNotification" \
    --add event bluetooth_off "IOBluetoothHostControllerPoweredOffNotification" \
    --set bluetooth "${bluetooth[@]}" \
    --subscribe bluetooth system_woke bluetooth_status bluetooth_off bluetooth_on \

Noticed a small delay when disconnecting a headset, but it does work in few seconds.

Edit: for some reason, it stopped working
Edit2: Now works. Had a problem with missing jq in the PATH leading to bluetooth script not working as expected.

Thank you, it is very helpful!

[diontr00]

bluetooth on and off events does not seem to work anymore ,are u experienced the same problem ?

[Pe8er]

_NSDoNotDisturbEnabledNotification
_NSDoNotDisturbDisabledNotification

These don't seem to work anymore in Sonoma.

           --set status "${status_bracket[@]}" \
           --subscribe status bluetooth_update volume_change

Got one issue that when I connect my airpods, these several items not triggered anymore. it was normal if I totally restart the sketchybar.
Also, here I set the update_freq is 10 seconds, why it doesn't rerun each 10 seconds? I guess if it rerun 10sseconds, it should appear even not triggered by the event

[marsjane]

Ok I fixed this by adding the updates=on for these items, I am using FelixKratz's setting and I just noticed the default updates value is when_shown. I should read the doc more carefully 😆

[RaiSaugat]

Will I be able to get the battery percent of the connected headset? My headset is not from apple. It's anker soundcore q45. I want to know if we can show the battery percent or not?

[theevilbit]

You can get many names just by checking the logs.

[Fau818]

Is there a Distributed Notification about changes in output devices?

I would like to change my volume icon to AirPods when the output device is my AirPods.

[Nikolaidp24]

I was trying to do the same thing and didn't find anything on the notification's side, so I tried writing a function in bash to switch audio and send event trigger that way, but ultimately just resorted back to using alias...

[diontr00]

As far as i experience is that Bluetooth Event are not working anymore on sonoma , before i can hook into IOBluetoothHostControllerPoweredOnNotificastion and com.apple.controlcenter with SwitchAudioSource to make the feature

[nima9]

if anyone knows if there is an event that fires on volume/mute change, please let me know!

[FelixKratz]

There is an integrated event in sketchybar for that: volume_change: https://felixkratz.github.io/SketchyBar/config/events

[diontr00]

These bluettoth events are not work anymore (Sonoma 14.2):
IOBluetoothHostControllerPoweredOnNotification
IOBluetoothHostControllerPoweredOffNotification
When bluetooth turn on and off those events are not triggered , anyone experience the same problem ?

[rogeruiz]

I've noticed that the com.apple.Music.playerInfo event stopped firing / being recognized by SketchyBar on macOS Sonoma. I use it as a backup for media_changed events not firing / capturing the $INFO. 😕

[MrJarnould]

Has anyone found a notification that detects changes between different Focus modes? While NSDoNotDisturbEnabledNotification effectively indicates when any Focus mode is activated and _NSDoNotDisturbDisabledNotification signals when any Focus mode is deactivated, I am unable to locate a notification specifically for detecting transitions between individual Focus modes.

[rogeruiz]

I haven't tried this but you can determine the focus mode using JSX. Here's a gist that can help you get started.

https://gist.github.com/drewkerr/0f2b61ce34e2b9e3ce0ec6a92ab05c18

[thewinger]

Has someone found a notification for input mute or not? Trying to have the mic_status plugin in SbarLua.

[Masstronaut]

Has anyone found a notification for when a diplay/monitor is connected or disconnected?
