Lua 5.0 (pre-release) -- quick comments I also wasn't able to get readline support, compiling in linux (slackware 8.1, mandrake 9.0, debian 3). Other than that the compiles worked great. I like the n

Now for portability: how do you detect the actual wordsize? The function uses an "unsigned int" and can use "cast_uint()" but we need a portable macro for defining the conditional code that will be c

Maybe it would be a little more "elegant" to use some macros to abstract the tests, and then add those 'ifdefs' around the macros. Something like this: luaL_argcheck(L, (MIN_INTFRM - 1) < n && n < (

Because `#t` and `__len` exist, there is a perception that Lua "has sequences". To me, in order for that to be true, there would need to be something that enforced the limitations of a sequence. Inst

OK, here is a fully-worked example. I figured that people might be using the crippled Windows NT console (at least, that's what I have here) so I didn't put in any VT100 codes; this will therefore do

Having written similar code in the past, here are some notes on Luiz's generally nice and certainly concise code: 1. It doesn't handle tables as keys. But it does assert so you at least won't continu
