Integer Slice Functions


The until function builds a range of integers.

until 5

The above generates the list [0, 1, 2, 3, 4].

This is useful for looping with range $i, $e := until 5.


Like until, untilStep generates a list of counting integers. But it allows you to define a start, stop, and step:

untilStep 3 6 2

The above will produce [3 5] by starting with 3, and adding 2 until it is equal or greater than 6. This is similar to Python’s range function.
