Hi,
Is there any guidelines for writing C libraries for lua aviable
somewhere ? If not, why not having a such page, maybe on the lua.org
website or lua-users.org ...
For example, what is the best way to implement luaopen_* functions, How
to register userdata's metatables and things like that.
Something else, I have my own way to register metatables which use
luaL_newmetatable with uri like the ones used in XML namespaces (xmlns)
to avoid collisions. For example:
void L);
lua_State* L) {
if(luaL_newmetatable(L, "http://purl.org/NET/louve/2006/foo";)){
lua_pushliteral(L, "key")
lua_push...(...);
lua_rawset(L, -3);
}
}
Using it:
/* create the metatable*/
push_metatable(L);
lua_setmetatable(L, -2);
Is it the best way to do it ?
Does evryone uses unique URI like me ? if not, how to avoid collisions
in the registery between libraries ?
