Lua - expected "end" (to close the "function" near <eof>), do not see the missing "end"

Question

I get an "end" error message, but I looked through all the code and cannot see it.

local Grid = {}
Grid.__index = Grid
function Grid.new(w, h) do
    t = {}
    setmetatable(t,Grid)
    for i=1,w do
        t[i] = {}
        for j=1,h do
            t[i][j] = {i, j, nil}
        end
    end
    return t
end
Grid.__call = Grid.new
return Grid

Here is the error:

lua: grid.lua:15: 'end' expected (to close 'function' at line 3) near <eof>

Answer 1

Put doin a line function. You have one endthat is relevant functionbut not appropriate (unnecessary) do. (Actually, the compiler considers that it endmatches do, and then complains when it does not see endfor this function.)

The syntax of the function body is approximately

functionname (params _opt ) end of block

(For simplicity, see the Lua link .)

A do . , end.
