How do I remove variables from an array in Harlowe?

Staghorn

So let's say I make an array of strings. Let's say it's called $candy, and contains "laffy" and "taffy".

Calling "$candy's 1st" gives you "laffy", of course. However, I would like to remove "laffy", in such a way that calling "$candy's 1st" gives you "taffy".

How do I do this? I see the occasional mention of (remove: ) but that doesn't seem to exist in Twine 2.

If you look at the Harlowe documentation you will see a (subarray:) macro, this is what you use to remove an element and then resize an array.

The format of the macro is (subarray: array, start_index, end_index), so for your example it would be:

(set: $candy to (subarray: $candy, 2, $candy's length))

Test Code:

Initialize the Candy Array
(set: $candy to (array: "laffy", "taffy"))
length: (print: $candy's length)
1st: (print: $candy's 1st)
2nd: (print: $candy's 2nd)


Use SubArray macro to remove first element from Array
(set: $candy to (subarray: $candy, 2, $candy's length))
length: (print: $candy's length)
1st: (print: $candy's 1st)
2nd: (print: $candy's 2nd)
