21. X.509 PKIX certificate parser using lpeg.Cmt (was Re: Elegant design for creating error messages in LPEG parser) (score: 312)

I meant to reply when you first posed the question but couldn't get around to it. The following is a basic PKIX X.509 certificate parser. I've refactored my working code into a single file. It's a wo

Another numbering scheme may be better, but I think now that numbered scopes are less readable/decipherable than named scopes. Interestingly, Lua already has named scopes: they are called lexical var

err.. that should read more like function f() for x=1,3 do local cont print(x) return function() break cont end end end f()()()()() -- > 1 2 3 (i.e. some type of coroutine)

Agreed. As neat as numbered break/continue are, I'd be satisfied with just C-style continue. -- Sent from my toaster.

A new version of my POSIX library is almost ready. I still have to write a reasonable test and perhaps some documentation, and so I'm not ready yet to release a tarball. However, since there are a fe

Are you thinking of the comment "The behavior of next is undefined if, during the traversal, you assign any value to a non-existent field in the table" concerning next/pairs? That doesn't apply to th

Really may I? I read from the manual that I may not. - how do you imagine to skip a pair? for k, v in ipairs(x) do if v="-skip" then k,v = ipairs(x, k,v ) continue -- eh else everything else i want

Or perhaps instead of "tagged block" a "named block" that could be used with functions too. function :name SyntacticalSugarName () end :name We could introduce real named functions in a orthogonal wa

That example was merely to illustrate the expressive power of the construct in emulating other control structures. You may want this expressiveness for code generation purposes, and it may also be ni

In Lua, we favor generic and powerful constructs. Actually, a 'goto' would be almost perfect. But its interaction with variable scoping is quite confusing in a language with first-class functions lik

Not much I guess but 5.2 is still a moving target in some aspects and so not much effort has been spent in luac. Attached is a patched (but still work-quality) version of print.c that works better t
