tolist Function

tolist converts its argument to a list value.

Explicit type conversions are rarely necessary in OpenTF because it will convert types automatically where required. Use the explicit type conversion functions only to normalize types returned in module outputs.

Pass a set value to tolist to convert it to a list. Since set elements are not ordered, the resulting list will have an undefined order that will be consistent within a particular run of OpenTF.

Examples​

> tolist(["a", "b", "c"])
[
  "a",
  "b",
  "c",
]

Since OpenTF's concept of a list requires all of the elements to be of the same type, mixed-typed elements will be converted to the most general type:

> tolist(["a", "b", 3])
[
  "a",
  "b",
  "3",
]
