Question

I was wondering how do I get a line into an array with lua in some sort of function

eg. FileToArray(“C:/file.txt”)?

I know I can use:
var = io.open(“file”)
Data = var:read()
But it only returns the 1st line, and no other lines.

Anyone know how to fix this or a different way? I’m new to lua and the file system stuff.

You can pass "*a" to read function, it should read the whole file:

local file = io.open("file-name", "r");
local data = file:read("*a")

And if you want to store each line in an array. Like Jane’s solution you can use
io:lines () – which returns iterator function (each call gives you a new line)

 local file = io.open("file-name", "r");
 local arr = {}
 for line in file:lines() do
    table.insert (arr, line);
 end
