If there is such a forum, I'll donate a linked list implementation. (It's included as an attachment.) It's implemented entirely in Lua, and the documentation is contained in comments at the beginning

My metamethods only have a special behavior if the number is a very specific NAN value. There are billions of NANs, so the chance of this value occurring normally is negligible. And the special behav

I am having an interesting time with token filters but now I've run into a snag. I probably do something very stupid.... but I don't know what. I have a module token.lua that implements the simplest

I had some luck with using a NAN value with a metatable for numbers. So now I have: NIL+x -> NIL NIL[x] -> NIL NIL[x]=5 -> no error But I'm still having 2 problems: 1) NIL==NIL gives false. That's be

I think there's been some confusion; I think you are using the sqlite driver from the Kepler project, but reading the documentation for the driver from http://lua.sqlite.org/index.cgi/index. If you c

Author: Andrew Starks <andrew.starks@...>

That is basically the explicit/implicit (defined/undefined) nil approach, not the table-index-is-vararg approach. The former requires less changes to Lua as is, but introduces a new value which inhe

Here is where I should have picked up from... I think if you define __index as defaulting to returning nil on undefined values, then it is not messy, except for one glaring issue. There would need to

Hi list, How do I write a "non-trapping" version of the "dostring" function that will propagates errors instead of just returning a nil and an error string? The default behaviour is that this code lu

A table is a table. There is no such thing as a sequenced table. If you have: t = {1, 2, 3, 4} print(#t) -- 4 t.foo = 2 print(#t) -- 4 print(t[4]) -- 4 print(t.foo) -- 2 -- continuing for below: t[5]

Tables in lua can not contain nil. This one of the things differentiating local variables and table "slots" ( globals are inside a table ). In fact, you assign nil to a table index to delete it. That
