array_contains
pub fun array_contains(array, value)Checks if a value is in the array.
Usage
import { array_contains } from "std/array"
array_contains([1, 2, 3], 2) // Outputs truearray_extract_at
pub fun array_extract_at(ref array: [], index: Int)Removes an element at the index from the array, and returns it; if the
index is negative or beyond the end, the function fails.
Usage
import { array_extract_at } from "std/array"
let array = [1, 2, 3]
let element = array_extract_at(array, 1)
echo element // Outputs 2
echo(array) // Outputs [1, 3]array_filled
pub fun array_filled(size, value = 0)Returns an array of length size with each element set to value; if size
is less than zero an empty array is returned
Usage
import { array_filled } from "std/array"
let array = array_filled(5, 1)
echo(array) // Outputs [1, 1, 1, 1, 1]array_find
pub fun array_find(array, value): IntReturns index of the first value found in the specified array.
If the value is not found, the function returns -1.
Usage
import { array_find } from "std/array"
array_find([1, 2, 3], 2) // Outputs 2array_find_all
pub fun array_find_all(array, value): [Int]Searches for a value in an array and returns an array with the index of the various items.
Usage
import { array_find_all } from "std/array"
array_find_all([1, 2, 3, 2], 2) // Outputs [1, 3]array_first
pub fun array_first(array)Returns the first element in the array; if the array is empty, the function
fails.
Usage
import { array_first } from "std/array"
array_first([1, 2, 3]) // Outputs 1array_last
pub fun array_last(array)Returns the last element in the array; if the array is empty, the function
fails.
Usage
import { array_last } from "std/array"
array_last([1, 2, 3]) // Outputs 3array_pop
pub fun array_pop(ref array)Removes the last element from the array, and returns it; if the array
is empty, the function fails, and the array will be unchanged.
Usage
import { array_pop } from "std/array"
let array = [1, 2, 3]
let element = array_pop(array)
echo(element) // Outputs 3
echo(array) // Outputs [1, 2]array_remove_at
pub fun array_remove_at(ref array: [], index: Int): NullRemoves an element at the index from the array; if the index is negative
or beyond the end, the array will be unchanged.
Usage
import { array_remove_at } from "std/array"
let array = [1, 2, 3]
array_remove_at(array, 1)
echo(array) // Outputs [1, 3]array_shift
pub fun array_shift(ref array)Removes the first element from the array, and returns it; if the array
is empty, the function fails, and the array will be unchanged.
Usage
import { array_shift } from "std/array"
let array = [1, 2, 3]
let element = array_shift(array)
echo(element) // Outputs 1
echo(array) // Outputs [2, 3]sort
pub fun sort(ref array: [], desc: Bool = false, version_sort: Bool = false): NullSort the array in-place.
Pass desc value true for descending order.
Pass version_sort value true for version sort,
this only applies to text arrays.
Usage
import { sort } from "std/array"
let array = ["15","-3","foo","bar"]
sort(array)
echo(array) // Outputs ["-3", "15", "bar", "foo"]sorted
pub fun sorted(array: [], desc: Bool = false, version_sort: Bool = false): []Return the sorted array, leaving the original array unchanged.
Pass desc value true for descending order.
Pass version_sort value true for version sort,
this only applies to text arrays.
Usage
import { sorted } from "std/array"
echo(sorted([-3,15,7,2], true)) // Outputs [-3, 2, 7, 15]
