Package trayhost is a cross-platform Go library to place an icon in the host operating system's taskbar.
- macOS - Fully implemented and supported.
- Linux - Not implemented.
- Windows - Not implemented.
On macOS, for Notification Center user notifications to work, your Go binary that uses
trayhost must be a part of a standard macOS app bundle.
Here's a minimal layout of an app bundle:
$ tree "Trayhost Sample.app" Trayhost\ Sample.app └── Contents ├── Info.plist ├── MacOS │ └── your_Go_binary └── Resources └── Icon.icns
Here's a minimal
Info.plist file as reference (only the entries that are needed, nothing extra):
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CFBundleExecutable</key> <string>your_Go_binary</string> <key>CFBundleIconFile</key> <string>Icon</string> <key>CFBundleIdentifier</key> <string>YourAppName</string> <key>NSHighResolutionCapable</key> <true/> <key>LSUIElement</key> <string>1</string> </dict> </plist>
CFBundleIdentifierneeds to be set to some value for Notification Center to work.
NSHighResolutionCapableto enable Retina mode.
LSUIElementis needed to make the app not appear in Cmd+Tab list and the dock while still being able to show a tooltip in the menu bar.
Most other functionality of
trayhost will be available if the binary is not a part of app bundle, but you will get a terminal pop up, and you will not be able to configure some aspects of the app.
