One person in our labs has work on this kind of method : generating on the fly c++ code, compile in background and reload dynamically the build library. The c++ code wasn't generated from Lua but it doesn't matter. The idea is the same and "seems" to be interresting, but I think time compiling and loading with this solution is a critical because even if it seems to work it can take a lot of time (millisecond upto few seconds) to do this. So I am interresting to see the result with such an approach...On Wednesday 22 February 2006 12:39, Lisa Parratt wrote: [...]Actually, my current cheat (because I can't be bothered to do what you've described yet ;) is to use the same syntax tree to compute all the primitive types of function dispatch, spit it out in a C file, compile it into a (dynamic) library, and then use that to dispatch the calls. Wonderfully portable, an acceptable level of hackiness - the only real downsides with it is it need preprocessing (but then so do the data structures from the syntax tree), and that it can't support varargs.Eeee! Acck! That's horrific! OTOH, as you say, it works... what compiler do you use? Do you run into problems that invoking the compiler takes an unacceptable amount of time? (In which case, tcc would probably really help you, particularly as you can use it as a code generation library...)
Oh, yes, for the record: Fabrice Bellard is scarily smart. Have you seen his other projects?
