Add lines of a draft.

Discuss in Drafts Forum

This action adds up each line of a draft and displays the total. It’s handy for those cases in between “I should use a calculator” and “I should use a spreadsheet”. Some use cases: adding up receipts, keeping track of per diem, splitting a bill.

Numbers can be integers or decimal:

10
3.75

Text, and everything after it, is ignored which is handy for adding notes:

# Twelve Days of Christmas

3  French hens
2  Turtle dovers
1  Partridge in a pear tree

Simple calculations can be done on each line:

5.00 * 2   multiplication
4.25 x 3   quicker than find multiply
100 / 2    division

Steps

  • script

    // Evaluate lines and accumulate the total
    
    (() => {
    
      const lines = () => {
        return editor.getText().split('\n');
      };
    
      const sum = (acc, l) => {
        try {
          l = l.replace(/\$/g, "");
    
          // Convert `2x3` to `2*3`
          l = l.replace(/[xX]+/g, "*");
      
          // Text to comments before eval
          l = l.replace(/[a-zA-Z]/,"//");
    
          l = l.replace(/#/,"//");
      
          let f = eval(l);
          if (!Number.isFinite(f)) {
            f = parseFloat(l);
          }
    
          if (Number.isFinite(f)) {
            acc += f;
          }
        }
        catch(e) {
        }
    
        return acc;
      };
    
      const t = lines().reduce(sum, 0);
      alert("total: " + t.toFixed(2));
    })();
