Question

I need to load file to Lua’s variables.

Let’s say I got

name address email

There is space between each. I need the text file that has x-many of such lines in it to be loaded into some kind of object – or at least the one line shall be cut to array of strings divided by spaces.

Is this kind of job possible in Lua and how should I do this? I’m pretty new to Lua but I couldn’t find anything relevant on Internet.

To expand on uroc’s answer:

local file = io.open("filename.txt")
if file then
    for line in file:lines() do
        local name, address, email = unpack(line:split(" ")) --unpack turns a table like the one given (if you use the recommended version) into a bunch of separate variables
        --do something with that data
    end
else
end
--you'll need a split method, i recommend the python-like version at http://lua-users.org/wiki/SplitJoin
--not providing here because of possible license issues

This however won’t cover the case that your names have spaces in them.
