Status bar (Agent) app for reacting to a theme change (Dark to Light and vice-versa).
The status bar icon will change to match DARK (moon) and LIGHT (sun) theme.
On theme change it can run a custom script
or call a webhook
You will need cocoapods installed and running:
$ pod install
After that open MacOSThemeDetector.xcworkspace in XCode and hack away.
Pre built binaries are loaded into the releases page. Just download and unzip them.
