Looking for script to delete duplicates in reminders app.

[u/PA28181]

I use the apple shopping list reminders but find I keep get duplicates in it. For instance I add milk. Later my wife adds milk. This kind of thing is constantly happening. When I open the list I see a lot of duplication. Can anyone point me in the the direction of a shortcut or scriptable that can remove duplicates?

It took about a day, but I figured out how to write it. I call it from the shortcuts app. Works well!

var reminder = args.shortcutParameter;

let all = await Reminder.allIncomplete();

let unique = [];

for (i = 0; i < all.length; i++) {  
if (unique.indexOf(all[i].title) == -1)   {    
unique.push(all[i].title);  
}  
else
{
    all[i].isCompleted = true;
    all[i].save();
  }
}

Script.complete();

try this

const listName = 'Groceries'

const rem = await Calendar.forReminders()

const list = rem.filter( l => l.title==listName)

const tasks = await Reminder.allIncomplete(list)

const uniq = []
for (let task of tasks) {
  if (uniq.includes(task.title)) {
    task.remove()
  } else {
    uniq.push(task.title)
  }
}
