These APIs are still open to future evolution. In new major versions, they may change in backwards incompatible ways.

Summary

Entry	Description
all	Returns true if predicate returns true for every element of arr.
any	Returns true if predicate returns true for at least one element of arr.
combine	Merges all additional tables into tbl in order. When the same key appears in multiple tables, the value from the last table containing that key wins. Returns tbl.
extend	Appends all elements from each additional array into tbl in order, mutating it in place.
filter	Returns a new table containing only the key-value pairs from table for which predicate returns true.
keys	Returns an array of all keys in tbl. Order is not guaranteed.
map	Returns a new table with the same keys as table, where each value has been transformed by applying f to it.
reverse	Returns tbl with its elements in reverse order. If inplace is true, reverses tbl in place; otherwise returns a new array.

Functions and Properties

tableext.all

Returns true if predicate returns true for every element of arr.

(arr: { T }, predicate: (T) -> boolean) -> boolean

---

tableext.any

Returns true if predicate returns true for at least one element of arr.

(arr: { T }, predicate: (T) -> boolean) -> boolean

---

tableext.combine

Merges all additional tables into tbl in order. When the same key appears in multiple tables, the value from the last table containing that key wins. Returns tbl.

(tbl: { [K]: V }, ...: { [K]: V }) -> { [K]: V }

---

tableext.extend

Appends all elements from each additional array into tbl in order, mutating it in place.

(tbl: { T }, ...: { T }) -> ()

---

tableext.filter

Returns a new table containing only the key-value pairs from table for which predicate returns true.

(table: { [K]: V }, predicate: (V) -> boolean) -> { [K]: V }

---

tableext.keys

Returns an array of all keys in tbl. Order is not guaranteed.

(tbl: { [K]: V }) -> { K }

---

tableext.map

Returns a new table with the same keys as table, where each value has been transformed by applying f to it.

(table: { [K]: A }, f: (A) -> B) -> { [K]: B }

---

tableext.reverse

Returns tbl with its elements in reverse order. If inplace is true, reverses tbl in place; otherwise returns a new array.

(tbl: { T }, inplace: boolean?) -> { T }

---

tableext.toSet

(tbl: { T }) -> { [T]: true }
