string iteration

UTF8 strings in Lua^rt are iterable through the Lua^rt helper function each(), returning the next character in the string with each loop iteration. Each iteration returns the character as a string.

Example


--! luart-extensions
import console

console.write("\nEnter your name : ")
local name = console.readln()
console.write("\nLet me spell it... ")

for char in each(name) do
	console.write("["..char.."] ")
end
console.write("\n")
