Automagically Update TaskPaper Start Dates

Change all the TaskPaper `@start(currentDate)` tags to `@today`.

Since I've been experimenting with using TaskPaper again instead of Things, I've starting scripting TaskPaper a bit. Here's a fun little script that will update @start(..) tags that match the current date by removing the start date and adding @today. Combine this script with an app like EventScripts to run each time TaskPaper is activated to always keep your @start tags up to date!

var TaskPaper = Application("TaskPaper");
TaskPaper.includeStandardAdditions = true;
var todayAttr = "data-today";

var app = Application.currentApplication();
app.includeStandardAdditions = true;
var dateToday = app.doShellScript("date +%F");

function TPContextGetCurrentPath(editor, options) {
  editor.outline.groupUndoAndChanges(function () {
    editor.outline.items.forEach((item) => {
      const startDate = item.getAttribute("data-start");
      if (startDate === options.dateToday) {
        item.setAttribute("data-today", "");

var path = TaskPaper.documents[0].evaluate({
  script: TPContextGetCurrentPath.toString(),
  withOptions: {
