Question

I am new to Lua and am having some difficulties:

I am trying to create dynamic variable names:

local tblAlphabet = {"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"};

local count = 0;

for k, v in pairs (tblAlphabet) do

  count = count + 1;

  [v.."button"]  = ui.newButton{ --HOW DO I MAKE THIS WORK? I get syntax error

--some code here

  }

Answer 1

You can create a table which contains your variables.

local tblAlphabet = {"a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"}
local vars = {}
for k, v in pairs(tblAlphabet) do
    vars[v .. "_button"] = ui.newButton()
end

Then you can access vars via iterators or direct access (vars.a_button).
