issue #899 add date blocks

[ghost]

Addressing issue #899:

• Added blocks for date objects
• Compare, subtract dates and add/subtract days/months/years

The icons on the blocks are being repeated and I cannot see why. Also still need to add credit for the calendar icon, "Calendar by Edward Boatman from the Noun Project"

Block icon is repeating because the width is set to 1em (16px) but the icon is only 12px wide and the default for backgrounds is to tile them with repetition.

If you change

wb-expression[type=date]:before {
    background-image: url("http://localhost/waterbear/css/../images/icon/calendar.svg");
}

to

wb-expression[type=date]:before {
    background-image: url("http://localhost/waterbear/css/../images/icon/calendar.svg");
    background-repeat: no-repeat;
}

That should fix it.

Thanks! Fixed that issue. PR is ready for review.

I created a date 'now' and a date in 1965. I was able to subtract a day, add 4 months and all was well. Then I tried adding 50 years and got a date 100 years later. Just investigating now how that could have happened.

Ah, not in your code, it is a bug with how we handle variables. One more clue in a long-standing issue I've been trying to track down. Your code is fine. :shipit:

Some additional blocks to consider: accessor blocks to get the day of month, day of week (as a string), month as a number or string, year, print as a localized string or ISO8601 string ('YYYY-MM-DDThh:mm:ss.xxxZ')

For sure, I can get working on that tomorrow!
