Hi guys, I made a few enhancements in my small library to handle matrices in Lua. Grab the goodies at: http://www.dam.brown.edu/people/carvalho/luamatrix-0.1.tar.gz As usual, critics, opinions and su

Afaics, it's totally unnecessary. Every userdata you push via pushrawuserdata has a luaL_ref. Just use it to push the userdata back onto the stack: lua_rawgeti(L, LUA_REGISTRYINDEX, matrix->ref). The

Hi guys, I decided to tackle a little bit with a multidimensional matrix representation in lua, and I came up with a nice solution (I guess :)). The simplest way I found to allow correct indexing was

I think it is, but why? A simpler solution is: a = 2 + (nil or 0) + 5 -- a = 7 c = "Merry " .. (nil or "") .. "Christmas!" Cheers, Luis. - -- Mathematicians practice absolute freedom. -- Henry Adams

Also, there's an easy option in Vim editor for generating html from code in a variety of syntaxes -- all supported by Vim. There's some extra flexibility since one can generate for different styles (

Hi guys, Is there a way to *free* a variable? I mean, without resorting to garbage collection? Cheers, Luis. - -- Mathematicians practice absolute freedom. -- Henry Adams - -- Luis Carvalho Applied M

You probably need: extern "C" instead of: LUALIB_API You might need an underscore in front of the function name when loading it. Mark on 9/25/03 6:52 AM, Luis Carvalho at carvalho@fritz.cfm.brown.edu
