1. why tags? (score: 1)

Author: "John Belmonte" <jvb@...>

Hello, With recent mention of the designers meeting to discuss about what can be removed from Lua in mind... I've been studying Lua and I noticed that the concept of tags was not present in the langu

I'm considering using Lua on an upcoming project, but with most of my co-workers being Japanese the lack of any documentation has been a nagging concern. It's good to hear that some translation work

Recently I've been toying around with an implementation of overloaded functions in Lua. I ran into an issue that must be well-known by anyone working on Lua extensions. I found that at the lowest lev

Edgar's patch addressed two limitations of upvalues: - they may not be modified - only the next enclosing scope may be accessed Before reading his post, I had not realized that upvalues had these lim

I found that reading the paper "Lua-an extensible extension language" on the documentation page of the Lua web site gave me good insight into what Lua is all about. It has perspective that you can't

That sounds like a paradox... a simple assignment to what? I don't think the global table variable itself can exist as a global. For this reason I suggested a getter function globaltable(). However i

The macro system of Scheme, which is a very clean dialect of Lisp, is probably a good one to study. Following is a link to the macro chapter of "An Introduction to Scheme and its Implementation". Pos

Recently I had a go at implementing a module system in Lua. I'll describe how it works and mention the limitations with Lua I ran into. My motivation was to make a better module system than what is p

Speaking of orthogonal handling and upvalues, I would like to use the upvalue syntax in the global scope. Combined with your patch I could just write %var everywhere without having to think about wha

I always write C++ loops as "for (int i; ... )", so the Lua for loop is perfectly natural to me. In practice I rarely need to access the iterator variable outside the loop, and maybe that's when I'm

12. function kidnapping (score: 1)

Given some variable definitions in the global scope n = 55 function func(x) return n * x end Lua allows us to move such variables to a table using the language's reflexive facilities or manually: t =

via Of course that depends on how you implement the tagmethods ("getglobal", etc). Probably you would have them search in t first, and if it isn't there use rawgetglobal(). Or maybe when the namespac

I'm having trouble figuring out tolua 3.2. Using the pkg file below, why isn't valid C code generated? (Problem seems to be caused by the "unsigned".) Secondly, how do I create an instance of my stru

Why not have lua_type return an enumeration of the types? This will eliminate the "dirty trick" (which everyone will certainly do instead of messing with string compares). If it's believed that strin

Section 4.8 of the manual says that the tag method events are hard coded into the interpreter. Does this apply to the setglobal/getglobal events even though they are defined in the basic library? I'm
