It's been a while, but vstruct isn't dead, only sleeping - while I rewrite the parser from the ground up, and then rewrite pack() and unpack() twice. And now it awakens, with the first beta of 1.1 re

Hi Ivko, I'd be very interested in seeing this. In my view Pluto adds a lot to Lua, I'm surprised it isn't brought up more frequently. The prospect of a version that has been tried and tested with th

Hi, The luaL_Buffer mechanism uses a fixed size buffer on the C stack (LUAL_BUFFERSIZE = BUFSIZ = usually 4K or 8K) and pushes partial Lua strings on the Lua stack if the buffer overflows. No memory

I played around with that already. My attempt was like this: lua.h defines a macro LUA_MODULE(module_name, start_func). Every module (a static or dynamically loaded library) has one instance of this
