We could fix this opname issue as suggested, but there are probably other issues like that, eg indexing the constant array or the locvars array. Keep in mind that luac, like the rest of Lua, assumes

LOL. Right, which is what I was saying about the array vs pointer stuff! :) The StackOverflow article pretty much stated the same thing. I guess I just never really thought of the array indexing symb

? If two distinct userdata?s return the same type+value for __key Lua will think they are the same value and bad things will happen if they are put in the same table, possibly crashing Lua. Not good.

What if I have a data structure like: struct foo { struct { int a; int b; } list[]; }; where list could be a billion items long? That's not at all uncommon in data mining. Even multi-gigabyte XML and

Even absent the garbage objects, all those indexing operations aren't helping performance, and this solution doesn't remedy that at all. Using (abusing?) Lua as a convenient interface to poke and pro

Hello, I have recently been writing a JSON parser[1] to be used by our Lua web framework[2]. Since JSON arrays may contain null values, and since one of the library's goals is to represent JSON null

not sure i follow you. currently next({[1.0]=true}) returns 1.0, but the key is internally just '1' (well, it's not a key, but an index on the array part), it's converted to integer when entering arr

158. what to make of this fellow named __ipairs? (score: 22)

What are we to make of this fellow named __ipairs in 5.2.0-alpha? The Reference Manual specifies the mechanics of `__ipairs` [1] but not its intended purpose. This leads to many questions.... How sho

Hi all, I'm revising Penlight for a new release soon, and started experimenting with extending the List class. By making __index a function, it's easy enough to support negative indices, so that ls[-

Errrr, which people exactly? In C it is natural to have 0-based arrays because of the meaning of an array index (low-level memory displacement from address at which first element is stored, such tha
