Slack animations take a ton of CPU and thus battery. Wouldn't it be great if unplugging your laptop from its power source would automatically turn them off?
This is a bit of code for Hammerspoon that makes that happen.
AnimateSlack is just an Automator app that pulls my user token out of a keychain with security and curls a POST to some Slack API URL I forget the details of
| local previousPowerSource = hs.battery.powerSource() | |
| function batteryChangedCallback() | |
| local powerSource = hs.battery.powerSource() | |
| if powerSource ~= previousPowerSource then | |
| showBatteryStatus() | |
| hs.alert.show(powerSource) | |
| if powerSource == "Battery Power" then | |
| hs.alert.show("Stopping Slack animations") | |
| hs.execute("open -a AnimateSlack --args false") | |
| else | |
| hs.alert.show("Starting Slack animations") | |
| hs.execute("open -a AnimateSlack --args true") | |
| end | |
| previousPowerSource = powerSource; | |
| end | |
| end | |
| hs.battery.watcher.new(batteryChangedCallback):start() |
