now also works on negative numbers
copies reuslt to the clipboard
shows result in notification instead of appending

Calculates the sum of all numbers in the selection. If there is no selection, the entire draft is used as input.

The sum is then displayed as notification & copied to the clipboard.

Works with “.” or “,” as decimal seperators. Also supports with negative numbers, enabling the correct parsing of sequences like 2-4+3 as well.

Caveats: This action does not work with any kind of thousand seperator (“.”, “,”, or space), as they would introduce ambigious cases.

Steps

script

draft.saveVersion();

//gets selection, if no seleciton, gets draft
if (editor.getSelectedText() == "") {
	var textToCheck = draft.content;
} else {
	var textToCheck = editor.getSelectedText();
}

//match all numbers in text
let digitMatches = textToCheck.match(/-?\d+(?:[,|\.]\d+)?/gm);

//addition of all numbers
var sum = 0;
var commaAsSep = false;
digitMatches.forEach(numberAsString => {
	let numberToAdd = parseFloat (numberAsString);
	if (numberAsString.includes (",")){
		commaAsSep = true;
		numberToAdd = parseFloat (numberAsString.replace (",","."));
	}
	sum = sum + numberToAdd;
});

// Stringify sum, using "," as seperator when it was used
let sum_string = String(sum);
if (commaAsSep == true){
	sum_string = sum_string.replace (".",",");
}

// Copy to Clipboard
app.setClipboard(sum_string);
app.displaySuccessMessage("∑ = " + sum_string);
