Scriptable macOS application to show and control progress indicators
A code-signed and notarized build of this project can be downloaded from here.
Run one of the demonstration scripts in the scripts directory of this repository for an example on how to create and control progress indicators.
Basic syntax is:
tell application "Progress"
set myIndicator to make new indicator with properties {visible:true, title:"Processing…"}
end tell
repeat with i from 1 to 100
-- Do something
tell application "Progress" to tell myIndicator
set percentage to i
end tell
end repeat
tell application "Progress" to tell myIndicator
set title to "Done"
end tell
When the percentage is set to a value below zero an indeterminate progress is displayed.
The indicator is automatically set to be complete when the percentage reaches 100. No further percentage updates except with -1 are allowed past this point.
If there are no updates to a newly created indicator for 15 seconds, the user is presented with a cancel button.
If the cancel button is pressed your script has another 15 seconds to finish processing otherwise the user will be able to close the indicator.
If you would like to show an indicator without AppleScript then start the application from the command line or in a shell script with two arguments each pointing to a .json file.
First argument: Path to data file
Example:
{
"percentage": -1,
"title": "This is the title",
"message": "This is a descriptive message",
"icon": "/System/Library/CoreServices/Dock.app/Contents/Resources/[email protected]"
}
As long as the user does not cancel the progress, this file is checked every second for changes to be mirrored by the indicator.
Second argument: Path to cancel-file
Example
#!/bin/bash
~/Downloads/Progress.app/Contents/MacOS/Progress ~/Downloads/swift-progress/json/progress.json ~/Downloads/swift-progress/_cancel.json
Once the user presses the cancel button the cancel-file is created to give your application or script a chance to know of the user’s intent. At this point you are encouraged to delete the cancel-file which will update the indicator accordingly. If the cancel-file does not disappear within 15 seconds, the user is allowed to close the progress indicator and the cancel-file is deleted.
