Split and Join

You already cut strings with split() and glued arrays with join(). Both can do more.

The pieces of split() are strings, exactly as they appear between the separators, spaces included. Clean or convert each piece before you use it. An element of the result can be replaced through its index:

var items := "sword, shield ,bow".split(",")
print(items)
for i in range(items.size()):
	items[i] = items[i].strip_edges()
print(items)

["sword", " shield ", "bow"]
["sword", "shield", "bow"]

The second argument of split() is the one you met before: true keeps empty pieces, false drops them. A third argument limits the number of cuts. split(" ", true, 1) cuts only at the first space, which separates a command from the rest of the line:

print("say hello there".split(" ", true, 1))

["say", "hello there"]

rsplit() works the same way but counts the cuts from the right, so it can cut at the last dot of a file name:

print("save.backup.json".rsplit(".", true, 1))

["save.backup", "json"]

join() also accepts an array of numbers and converts each one to text: ", ".join([3, 1, 2]) is "3, 1, 2".
