19:56:36 <Figs> it's pretty basic
19:56:42 <Figs> I could do a better job with more time
19:56:51 <Figs> but I was just fed up with syntax tree generators yesterday :P
19:57:12 <Figs> if I keep doing this shit, eventually I'll have a full lisp-interpreter in C++ .... >.>
19:57:18 * GregorR watches Figs turn C++ into LISP
19:57:18 <oklopol> closer to lisp than your earlier parenthesis one, was my point
19:57:41 <oklopol> i recall us once before saying the same thing at almost the same second
19:58:10 <oklopol> you almost said that at the same second too :P
19:58:30 <Figs> #define node(s) tree(s) isn't really needed... I was just feeling lazy :P
19:58:33 <GregorR> Now, Plof3 will be trivially able to be turned into LISP
19:58:54 <oklopol> ah you added that syntax thing
19:58:57 <Figs> I don't really know enough lisp to convert the whole thing
19:59:09 <GregorR> Runtime-defined grammar! Weeeh
19:59:17 <Figs> but supposedly I only need about 7 functions...?
19:59:18 <oklopol> you know what the reason is?
19:59:29 <Figs> (according to (paul graham))
19:59:35 <oklopol> I WAS GONNA DO THAT FOR OKLOTALK YOU MIND THIF
20:00:25 <oklopol> lisp needs if + define + lambda + a few operators

20:02:03 <oklopol> GregorR: is grammar first-class?
20:02:23 <oklopol> can you pass it for the ultimate obfuscation

21:04:14 <GregorR> Why do I keep typing 's' :P
21:04:47 <GregorR> No, grammatical elements are not first class ... you could build a grammar which has constructs which themselves resolve to grammatical actions, and then pass around those constructs.
21:08:16 <GregorR> That is, grammatical elements are defined entirely internally and committed by operations in the stack code, but you could make an object which encapsulates that stackcode operation in a defined way.
21:10:45 <GregorR> (FYI, the stackcode itself is not directly accessible from user code, you need to define a grammar for it)

22:00:09 <ehird`> who wants to help me write the ultimate bf compiler i've had in mind for a while now?
22:00:16 <ehird`> it'll do BF->C, and some really heavy optimization
22:03:07 <ehird`> hopefully it'll be the most complete BF compiler out there

22:16:56 <ehird`> <crickets chirp, nobody cares>
22:47:07 <ehird`> yes, except i've had ideas for this one in my mind for a while now
22:51:12 <ehird`> like some various optimization techniques that i have not seen before
22:52:40 <ehird`> like x[x] -> dowhile loop
22:52:43 <ehird`> (i haven't seen that before)
22:56:16 <ehird`> it's still a reasonable optimization
22:56:20 <ehird`> and helps with code size
22:58:02 <bsmntbombdood> the obvious one is to pre execute all the code up to the first input
22:58:16 <ehird`> which is actually a really sucky optimization
22:58:25 <ehird`> what about infinite loops?
22:58:29 <ehird`> if you put a timelimit,
22:58:37 <ehird`> what if my code takes 5 minutes to execute but isn't an infinite loop?
22:58:47 <ehird`> do i get different, unoptimized code jsut because of the system i'm on is slow?
22:59:21 <ehird`> just because my code is a certain way it gets compiled in a different, perhaps slower way
22:59:53 <ehird`> also, i don't want my factorial program that calculates the factorial of 10 to be executed at compiletime
23:00:12 <ehird`> the x[x] optimization will be run after the useless-instruction removal
23:00:20 <ehird`> "<>" = "", so it'd be x[x] again
23:02:41 <bsmntbombdood> there's other ways to make it the same but unrecognizable
23:02:59 <ehird`> btw, the look-ahead and code-pattern-matching codes would be pretty advanced
23:03:08 <ehird`> it'd be damn hard to make e.g. the x[x] optimization fail
