Lua – ‘End’ expect (close the ‘function’), don’t miss the ‘end’

local Grid = {}
Grid.__index = Grid
function Grid.new(w, h) do
 t = {}
 setmetatable(t,Grid)< br /> 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

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

I received an error saying that the “end” is missing, but I looked at the entire code without seeing 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}< br /> end
 end
 return t
end
Grid.__call = Grid.new
return Grid

This is an error:

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

< /p>

Remove the do on the function line. You have a matching function at the end, but no match (unnecessary). (Actually the compiler thinks the end matches do, and then complains when it doesn’t see the end of the function .)

The syntax of the function body is approximate

function name( params_opt) block end
