String Module

The std/string module provides utility functions for manipulating and analyzing strings.

String Class​

Most string utility functions can be called either statically via the String class or as a method on the string instance (dot notation).

Static Methods​

len(s: string): number​

Returns the length of the string s.

charAt(s: string, i: number): string​

Returns the character at the given index i.

substring(s: string, start: number, end: number): string​

Returns a substring from start to end (exclusive).

indexOf(s: string, target: string): number​

Returns the index of the first occurrence of target in s, or -1 if not found.

toUpper(s: string): string​

Converts the string to uppercase.

toLower(s: string): string​

Converts the string to lowercase.

trim(s: string): string​

Trims whitespace from both ends of the string.

Example​

import { String } from "std/string.aura";

let s = "  Hello Aura  ";

// Static call
let trimmed = String.trim(s);

// Or method call
let trimmed2 = s.trim();

print s.trim().toUpper(); // "HELLO AURA"
