Hello, I have recently been writing a JSON parser[1] to be used by our Lua web framework[2]. Since JSON arrays may contain null values, and since one of the library's goals is to represent JSON null

It might not be suitable for you, but I just want to take this opportunity to plug my new multi-tasking library, it would do this pretty cleanly and bring a lot more options to the tablehttp://northa

Hi! I want lua code to be running as a single coroutine. For example, imagine C/C++ GUI application with logic written in lua. GUI event loop runs in C/C++, and lua code needs to drop back to it when

These seem like quite useful extensions, although I'm not sure what the difference is between the error hook and the handler set by xpcall... -- Sent from my toaster.

Hi. The very cool Tilde debugger makes the following modifications to the Lua core in order to make the debugger more usable: * A hook to catch errors, allowing the debugger to break at the point of

Here is a token filter written in C that expands constants from a table. For simplicity, I've used a global table named _CONSTANTS. --lhf /* * proxy.c * lexer proxy for Lua parser -- implements cons

However at a formal (rather than implementation) level would using an unadorned token really cause ambiguities? It would be neater without a special syntax and it should surely be possible to disambi

You can set a line hook that checks for the specific line you want to break. Something like: setlinehook (function (line) if line == <line> then <do something> end end) But this will not let you mak

In Lua, many special characters are idle, e.g. !, ?, @ etc. Lua 5.2 makes it easy to bring these characters into the syntax as alphabetic or space characters via the table in lctype.c. Things become

That's a shame, sort of syntactically. This has always puzzled me. Under what circumstances would you want to put a statement after return or break? It could not possibly be executed, and I'm quite

Woops. I hadn't yet seen the "official" version. So to atone, here's a better patch: first, I call using_history, which I forgot before, secondly, the lines you type are only entered into the history

Personally I find break (and it's younger brother continue) rather handy in certain situations (though apparently some people seem to think that kind of hackish or something). I'd love to see break r
