Out of context, the statement can be considered nonsense. In context, it isn't. The rest of the sentence talks about indexing a table with it, where *only* lua's equality definition applies. Communic

Sorry, now I'm really confused: {1,2} and {1,2} look visually identical to me. And what is [1,2]? Does that have any meaning in Lua? (When I tried it, I thought I got a syntax error.) Thanks, Eric

It would be highly surprising, because {1,2} and {1,2} are different[1], so indexing with them would give a different cell each time. OG. [1] Different tables, even if they have the same contents, he

Hello, I know that tables don't preserve order in case of an associative array. but I 've got the following code (didn't scoped them for the ex): -- iterator = 0 basic_table ={} str for x = 0,5 do it

Have you considered allocating your FFI arrays to be one longer than they need to be, and then remembering to offset the pointer to the array by one when you pass it to external C functions. Not exac

You can establish the relationship in two ways: 1) Use luaL_ref() to create a reference to the matrix, and store it in the vector struct. This will pin the Matrix until you release the ref (which you

Thank you for the responses. I went with Jerome's suggestions and now I have a few follow-up questions. As you suggested, I introduced a new MyVector userdata type which gets created and returned on

local a, b, c = t[ 1 ], t[ 2 ], t[ 3 ] c should be equal to t[ 3 ] even if t[ 1 ] and t[ 2 ] do not exist. Of course, but it would seem reasonable that: exists(a) --> false exists(b) --> false No, th
