particular (I'm presuming Renato's comment was about modules, not globals.) I'm tending to think the same way these days. I view Lua as second-to-none in the areas of configuration and embedded scrip

The other problem with this is that it's quite strange for the word "global" by itself to mean "don't use globals by default".

I think lhf is forgetting that the globals function is not available after you switch out the global table. You'll have to store a local reference to at least that function. -John

As someone who often makes patches against the official distribution, I'd like to suggest consistent indenting in the Lua source code. From just sampling a few files, I see that some have indenting o

I've implemented this as a power patch (http://lua.swiki.net/5). I haven't tested it much, but if anyone has a problem send me the details and I should be able to fix it. I didn't change existing opc

I realized that a subtle issue about making this change to Lua is that it requires the vm to know about lists. (It looks like in Sol, Edgar gets around this by using different semantics, where a list

Ah didn't see that, thanks for the correction. [1] I think it's too useful to have nil's in a list. I couldn't see giving that up. -John

The issue of nil as false has been well-discussed, and the Lua authors already admit this weakness in the paper "The Evolution of an Extension Language: A History of Lua". Independent of that issue h

I see your point there! A few messages back you corrected my statement about the vm not knowing about lists, but I should have said the vm doesn't know how to compute n given an arbitrary table. That

In the following from section 4.4.4, "t" in the next calls should be replaced with "_t". A for statement like for index, value in exp do block end is equivalent to the code: do local _t = exp local i

At one time Edgar and I partially worked through some scenarios for adding bools to Lua (see http://lua.swiki.net/12). There are some sticky issues as you have to trade off between usefulness and bac

I don't have any complaint about moving to Yahoo. However I'd like to point out that just because they don't attach ads today doesn't mean they won't change their policy tomorrow. If you are opposed

If you have control over the Lua environment it would make more sense to just export the info available to C. For example from <float.h>: DBL_DIG DBL_EPSILON DBL_MANT_DIG DBL_MAX DBL_MAX_10_EXP DBL_M
