In the 4.1 alpha release, a few things bother me about the contents of the LUA_PRIVATE ifdef in lua.h, called "useful definitions for Lua kernel and libraries". If something is said to be useful, tha

In my project I gave up on using Lua in the "main loop" long ago and just confined it to init time. Even so it's much better than life-before-Lua. Still, I'm interested in seeing how others manage in

Such an incremental garbage collector will allow hard real-time deadlines to be met, but will not solve fragmentation issues. These are separate problems. Lua's memory use can be tuned to alleviate g

Along these lines I'd also recommend the article "Memory Management in C++" by Nathan C. Myers (http://www.cantrip.org/wave12.html). It suggests how to unify memory management and work with several h

I'm a fan of both Debian and Lua, but allow me to play devil's advocate... what is the purpose of the binary distribution? Who is it useful to and how?

So the binary package includes the headers and library? I thought something like that belongs in a -dev package? Anyway, especially with 4.1, there are several configuration options implemented with

I agree with this, but will try to explain it more clearly. First let's throw out the term "game programming" as too general. A graphical strategy game running on a PC is worlds apart from a first-pe

About the -- comments, a subtle annoyance is that the standard diff tool (with common -u option) uses '-' to mark deleted lines, so deleted Lua comments are hard to catch. Since Lua ended up supporti

I'm not sure how useful this will be in practice. Is the point to shave bytecodes? Maybe it's not an issue for the intended audience. Furthermore in utility libraries I've written, functions often h
