Usage: widget [target] <data> ...
|
||||
|
||||
Update widget on device from which this function was installed with a number of content parameters that can be string, progress, icon, target, color, url or shortcut.
|
||||
|
||||
Each argument type is derived from input, where the first argument is assumed to be a target if it matches a target configured on the widget.
|
||||
|
||||
Progress has the form: 50% or 110/220
|
||||
|
||||
Icon must match valid SF Symbol name such as globe or terminal.fill
|
||||
|
||||
Colors must be hex colours such as #000 #ff00ff where the color is used for later content and 'foreground' switches back to default colour
|
||||
|
||||
Target is used to send different content to different widgets after configuring the widgets with different target identifiers which requires the pro unlock. The target parameter is never assumed unless --target is used and is effective until next --target parameter allowing updates of several widgets with a single command
|
||||
|
||||
URL is used when tapping the widget and is assumed for arguments starting with https:// and other schemes are supported by using --url
|
||||
|
||||
Shortcut works like URL running the Shortcut with the given name and is never assumed without --shortcut
|
||||
|
||||
String is the fallback type if nothing else matches, but content type can be forced for next parameter with --progress, --icon, --color, --text or --target with something like:
|
||||
widget --text "50/100"
|
||||
|
||||
You can update several widgets at once by using --target to send all parameters until the next --target to a particular widget. Updating several widgets at once allows more total updates per day.
