00:25:03 <dbc> Is Haskell intrinsically asymptotically slower than C for two-dimensional cellular automata?
00:25:27 <pikhq> Intrinsically? I doubt it.
00:25:44 <pikhq> Typically? Likely.
00:25:54 <pikhq> You can do some crazy stuff with C.
00:26:27 <dbc> Like use random-access mutable state :)
00:26:38 <MissPiggy> dbc, lazy data struturse are asymptotically slower than mutable ones
00:26:39 <dbc> Ooh, crazy!
00:26:40 -!- SimonRC has joined.
00:26:47 <MissPiggy> dbc, good thing haskell has mutation :P
00:26:50 <oerjan> you can do that in haskell too you know
00:26:59 <pikhq> MissPiggy: And Haskell allows strict data structures.
00:27:09 <pikhq> And mutable ones, too.
00:27:17 <MissPiggy> I am talking about a well known theorem
00:27:36 <MissPiggy> it's so well known that I don't know it's name or who proved it..
00:27:40 <pikhq> And GHC will often compile things into direct mutation.
00:27:50 <pikhq> (when laziness doesn't change semantics, IIRC)
00:27:59 <cpressey> Nick what's-his-name did a proof that sounds like what you're talking about
00:28:50 <cpressey> That LISP as a model of computation is slower than Turing machines
00:29:12 <MissPiggy> he doesnt have a publications list? grrr
00:30:24 <cpressey> I'll see if I can find the paper. Unfortunately, gotta go now. Later.
00:30:27 -!- cpressey has left (?).
00:30:36 <oerjan> dbc: if by asymptotically slower you mean more than a constant factor, then i don't see why haskell should be that for 2d ca's
00:30:47 <pikhq> Nope, just a bunch of Haskellians in here.
00:31:21 <oerjan> you might need to force some strictness not to get unexpected pauses between things, though

01:22:24 <Sgeo_> There was a recent revamp of TC definition?
01:22:54 <MissPiggy> I was _trying_ to figure out if it was a real person or not

01:26:55 <Sgeo_> Is crappy BF code common?

01:27:35 <lament> it's been done many times

01:30:38 * Sgeo_ is slightly insane
01:31:27 <lament> every slightly-optimizing brainfuck compiler does it
01:31:40 <Sgeo_> lament, what about outputting to BF code?
01:31:56 <lament> i think i've seen that
01:32:43 <Sgeo_> How many tools are there to turn BF code into PSOX-compatible BF code?
01:33:06 <Gregor> Does "PSOX-compatible" mean "Without outputting any \0s"?
01:33:47 <Sgeo_> Um, if you had that plus the PSOX handshake, that would work
01:34:02 <Sgeo_> I was thinking of just escaping everything, though
01:34:30 <Gregor> Probably difficult if you don't also make them take 2x memory or something.

01:39:42 <Sgeo_> virtujix, do you love me?
01:43:27 <oerjan> Sgeo_: in any case haskell _should_ be excellent for doing such a thing if you choose to do it
01:46:07 * Sgeo_ isn't sure how he'd make a bidirectional list
01:46:43 <coppro> if you absolutely must, you can have two lists and shuffle elements from one to the other
01:47:16 <oerjan> you can use two lists, one for the part previous and one for the part after (this is known as a _zipper_ of lists)
01:49:38 <Sgeo_> Hm, I think http://www.haskell.org/haskellwiki/Zipper may be exactly what I need
01:49:44 <Sgeo_> Note: I haven't started writing any of this yet

01:51:10 <Sgeo_> Except without the BFComment
01:51:23 <Sgeo_> And just plain BFAdd | BFSub etc
01:53:06 <Sgeo_> I should use Integral instead of Integer

04:40:12 * Sgeo just gave some bad advice in ##C++
04:40:37 <coppro> no, it was to use globals
04:40:50 <Sgeo> coppro, can you please come up with a better answer?
04:41:07 <coppro> Sgeo: pass it as an argument?
04:41:21 <Sgeo> coppro, aw_event_set() needs a function that takes 0 arguments
04:41:22 * oerjan doesn't actually know c++
04:41:43 <coppro> Sgeo: Oh. Then yeah, globals :(
04:42:10 <Sgeo> There's no answer with classes or functions returning functions? Although this guy is a beginner, so
04:42:26 <Sgeo> Plus, best not to overcomplicate this, I guess
04:42:30 <coppro> Sgeo: not if it expects a callback function
04:42:36 <coppro> (which, additionally, should be extern "C")
04:42:44 <pikhq> oerjan: Rejoice in that.
04:43:05 <Sgeo> coppro, wait, the callback function needs to be extern "C"d?
04:43:21 <coppro> Sgeo: If the library is a C library, which I assume it is
04:43:40 <Sgeo> It is itself extern "C"'d
04:43:46 <pikhq> Then yes, it needs to be extern "C"'d.
04:43:53 <pikhq> C++ has a different calling convention.
04:43:55 <coppro> yes, then the callback must also be extern "C"
04:43:56 <virtuLORD> coppro: Where their worm dieth not, and she said: verily, i say to you, which stood in all the things also to be extern "c.
04:44:44 <Sgeo> His callback uses a bunch of C++ stuff
04:44:56 <pikhq> Sgeo: That's perfectly valid.
04:45:12 <coppro> extern "C" only affects the external parts of the function; they can still use C++ features inside
04:45:14 <pikhq> Just so long as the callback can be called from C.
04:45:21 <oerjan> Sgeo: sounds like the problem is that C functions cannot simulate full closures? i recall haskell's ffi implementation requires self-modifying code because of that
04:45:36 <coppro> oerjan: yes, that's the problem
04:45:58 <Sgeo> coppro, want to actually help out in ##C++ ?
04:46:00 <virtuLORD> Sgeo: And aduram, and lachis, and to his friends and neighbours, saying to the help of the city of letters. . .Perhaps so called from c.
04:46:46 <Sgeo> What will happen if extern "C" {} isn't used?
04:46:49 <pikhq> oerjan: C functions are implemented using nothing more than a string of machine code that uses a set amount of stack.
04:47:00 <pikhq> Sgeo: Then it's undefined behavior.
04:48:21 <coppro> pikhq: Actually, a strict interpretation of the standard would say that it's ill-formed

18:44:42 * cpressey is starting to agree with Steve Yegge: there is something very, very wrong with Python's culture. I don't agree with him about what's wrong with it. And it only has an indirect effect on the design of the language itself, of course. But still, ... yeeeesh.
18:45:31 * olsner spreads some python hate around
18:46:38 <cpressey> MissPiggy: Was that a literal or rhetorical response?
18:47:05 <MissPiggy> I want to know more, what do you find wrong with python culture
18:47:42 <cpressey> Well, I'm still trying to figure out what it is.
18:48:32 -!- jcp has quit (Quit: I will do anything (almost) for a new router.).
18:51:15 <cpressey> Well, I was reading the documentation for the pickle module earlier.
18:52:02 <cpressey> There's something just backwards about how it's written. It's not that I can't read it, it's that it seems to be written with a completely different sense of "what's the most relevant?" than most readers would (I'm guessing) have.
18:52:27 <cpressey> Like, have you ever heard of Grice's maxims? About relevance in conversation. It's a bit like it's bending those.
18:53:11 <cpressey> Then I noticed that lots of Python documentation has the same feel to it.
18:54:23 <cpressey> Steve Y's theory is that the Python community has no sense of humor (ironic, considering the origin of the name) and is not self-critical. Could be that.
18:55:15 -!- coppro has joined.
18:55:52 <cpressey> I don't even want to get into the *design* of the pickle module... it makes Java's serialization look like fine silk in comparison.
18:56:12 <MissPiggy> well a lot of people just quote monty python verbatim, and laugh, but that's not really in the spirit of monty python is it
18:57:29 <cpressey> Oh, and then there's the fact that they decided to call it "pickling" instead of some more widely accepted term like "serialization".
18:58:10 <cpressey> And justify that choice by saying "...to avoid confusion."
18:58:49 <MissPiggy> I think python is a trap to suck newbies away from the path of light
19:00:36 <cpressey> Could be. Or maybe it's a plot to get a large number of 0-length files named "__init__.py" onto people's filesystems.
19:04:02 <MissPiggy> here's my thought experiment: It's a WYSIWIG WIZARD that takes some options like Syntax: algol, prolog, lisp, ML Execution: strict, lazy, nondetermininstic and so on, maybe some special options too: [-] lambda [-] syntax macros [-] textual macros
19:04:32 <MissPiggy> the first idea was that when you click 'go' it just produces an interpreter
19:04:47 <MissPiggy> but there's more fun thinking about other things you could produce instead of an interpreter
19:05:15 <cpressey> I take it that the set of operations is (aside from whatever the special options might do) fixed?
19:05:56 <cpressey> Wait, "WYSIWIG"? What You See Is What I Get? :)
19:06:33 <MissPiggy> oh geez, WYSIWIG is totally the wrong term -- you're right

19:08:53 <MissPiggy> Python's lack of semi-colons makes me uneasy - it's like standing at the edge of a cliff with no guard-rail... :-S
19:09:16 <coppro> Sgeo: I have autojoin, it just takes a while since the server has to process requests for 11 channels
19:09:45 <Sgeo> All is forgiven ;(
19:11:33 <lament> MissPiggy: semicolons are optional, you're free to put them in
19:12:28 <cpressey> Lua's optional semicolons are a bit more worrisome, as there's no offside rule (indentation-based-syntax) in Lua.
19:14:42 <lament> uhhh he's okay i guess?
19:15:23 <cpressey> If you really do mean WYSIWYG, it would be entertaining to see a program I've written switch between syntaxes on-screen.
19:16:09 <cpressey> Or MissPiggy's ex = KermitTheFrog
19:16:10 <AnMaster> <cpressey> Could be. Or maybe it's a plot to get a large number of 0-length files named "__init__.py" onto people's filesystems. <-- what would the point of that be for python modules?
19:16:19 <AnMaster> I thought you didn't need that module in general
19:16:29 <AnMaster> not sure what it is used for actually
19:16:38 <cpressey> AnMaster: It makes the directory a package, so that you can say dir.module
19:17:20 <cpressey> Ugly approach if you ask me...
19:17:46 <cpressey> Oh, and it can include startup code for the modules in that dir
19:18:09 <AnMaster> couldn't you just do that thing for any directory?
19:18:29 <AnMaster> relative the module search path
19:18:52 <cpressey> AnMaster: Like Perl (I think) does? Sure.
19:19:09 <AnMaster> if you specify foo.bar and your module search path is: /blah:/quux then it would look for /blah/foo/bar.py and /quux/foo/bar.py
19:19:59 -!- Gracenotes has joined.
19:19:59 <AnMaster> cpressey, python's approach would be the same plus check "does a file __init_.py exist?
19:21:29 <cpressey> Well, python's vesion does let you say "import dir" (which will import the __init__.py file in that dir), which makes it easier to turn a module into a package at some later point.
19:22:16 <cpressey> Overall, I'd much rather have module/package names independent of my filesystem layout though, at least potentially.
19:22:56 <AnMaster> cpressey, so how would it locate packages and modules then?
19:23:24 <cpressey> Some kind of configuration file. It could fall back to some regular mapping if the file doesn't specify.
19:23:28 <AnMaster> and yes, some special file could be used it you needed init stuff or that thing with import dir
19:23:56 <AnMaster> the stupid bit is when you end up with zero length such files
19:24:18 <AnMaster> but there is an easy way to solve that
19:24:24 <AnMaster> just add a license boilerplate in it
19:25:53 <cpressey> I may complain about Python, but it's not like it's C++ or SOAP.
19:26:22 * cpressey starts screaming uncontrollably at the thought of SOAP libraries implemented in C++
19:26:42 <AnMaster> SOAP isn't a programming language afaik?
19:27:08 <cpressey> http://72.249.21.88/nonintersecting/2006/11/15/the-s-stands-for-simple/
19:27:09 <AnMaster> cpressey, they would use templates to implement it?
19:29:25 <cpressey> AnMaster: Oh I certainly hope they would. Otherwise that beautiful template facility would just be going to waste!
19:33:05 <AnMaster> and that link, funny, yet depressing
19:34:30 <Sgeo> sleep :: Person -> IO ()
19:34:41 <Sgeo> isTired :: Person -> IO Bool
19:37:44 <fizzie> I would add "realistic" to the list of adjectives.
19:48:38 <augur> i dont get the point of soap.
19:48:52 <cpressey> augur: That means you're sane.
19:49:09 <augur> but like, if i need to transfer data, i'll just use JSON.
19:49:18 <augur> or if im feeling anti-JSON and roll my own
19:49:31 <augur> LISP is a nice enough literal format too.
19:49:50 <augur> easier to parse than JSON or XML too.
19:57:42 <cpressey> SOAP is a Wrapper without a Cause...

20:33:58 <AnMaster> <augur> LISP is a nice enough literal format too. <-- did you mean: S-Expressions?
20:34:35 <AnMaster> lisp is the language. When the same kind of thing is used as a data format it is s-expressions

20:44:29 <cpressey> AnMaster: Actually, I'm not sure. The GIL is an implementation issue (isn't it?) And one of the nicer things about Python is that it's at least *trying* to separate language from implementation. Not trying hard enough, but at least trying.
20:46:02 <cpressey> But, the GIL is something that sucks about CPython, surely :)
20:48:36 <cpressey> In FreeBSD they used to have an equivalent thing... they called the Big Giant Lock

21:46:12 -!- coppro has quit (Quit: car trip).
21:46:21 <cpressey> AnMaster: Code shouldn't be allowed to monkeypatch my classes. If it tries, something ought to break.
21:47:08 <cpressey> Yes, "monkeypatch". http://en.wikipedia.org/wiki/Monkey_patch
21:47:44 <AnMaster> cpressey, so use a language compiled to machine code. Sure it can still be done there, but would be painful
21:48:06 <AnMaster> cpressey, also make a variant of befunge that forbids it
21:49:46 * Sgeo might end up monkeypatching getElementById on a school website
21:50:12 <cpressey> That's kinda what I'm saying -- if I have to switch to a different language (not that that's practical), I might as well design my own
21:50:27 <Sgeo> AnMaster, on Chrome, getElementById doesn't seem to be working the way I think it should, and that's causing problems
21:51:06 <Sgeo> I guess that would entail making a page that can reproduce the issue
21:51:18 <AnMaster> that would be helpful at least
21:54:16 <AnMaster> <cpressey> But I want more. I want values to be marked with the amount of computation that was taken to obtain them. Then I could guard against the use of e.g. computed dict keys. <-- I don't get this
21:54:20 <cpressey> Monkey patching is the self-modifying code of the scripting world. Its presence is also just as confounding to bug-hunting.
21:54:25 <AnMaster> cpressey, also __slots__ as I said
21:54:37 <cpressey> I mean, I can live without static types, but does EVERYTHING have to be undecidable??
21:54:56 <cpressey> AnMaster: __slots__ will do that?
21:55:01 <AnMaster> cpressey, at least python parses into a nice AST, with LL(1) even iirc
21:55:19 <AnMaster> cpressey, well not sure what you meant, but if I didn't completely misunderstand you: maybe
21:55:40 -!- MigoMipo has quit (Remote host closed the connection).
21:55:53 <cpressey> I mean I want foo(int) to be able to tell if it was called with: foo(5) or foo(2+3)
21:55:54 <AnMaster> cpressey, __dict__ isn't used with it at least. So making up a new self.foo on the fly won't work unless __slots__ include a foo
21:56:11 <AnMaster> not sure how it works for functions
21:56:25 <cpressey> AnMaster: oh, you mean __slots__ to guard against monkey patching. I see.
21:56:28 <AnMaster> cpressey, anyway, anyone could just copy your source file and make some changes, no?

21:56:51 <AnMaster> <cpressey> I mean I want foo(int) to be able to tell if it was called with: foo(5) or foo(2+3) <-- compile time transformations?
21:56:54 <cpressey> AnMaster: I don't care if they copy it.
21:56:58 <AnMaster> I assume those would be constant folded
21:57:31 <AnMaster> cpressey, also if they do that sort of stuff, they only have themselves to blame
21:57:48 <AnMaster> since it would propagate the constant value of a
21:57:56 <cpressey> AnMaster: You're thinking in a completely different paradigm -- this isn't library code for other people's use -- this is in-house stuff.
21:58:35 <cpressey> If there's some class out there that's monkeypatching my class, and my tool/app/page/whatever is crashing because of it, I can't just blame the author of the other class
21:58:44 <AnMaster> yell at them if they screw stuff up? Plus some sort of coding guidelines might help
21:59:48 <cpressey> Yes, but I've found culture always changes more slowly than code. I can't just start telling everybody their code sucks.
22:00:31 <pikhq> Most code does, in fact, suck.
22:00:36 <pikhq> And quite horribly, too.
22:01:25 <AnMaster> this is why academical work is best. That way you don't have to maintain it for that long, and people around you tend to not be *that* stupid.
22:04:12 <cpressey> Oh, academic work is fantastic that way. It doesn't really have to work, you just have to be able to defend it from questions from people who don't really understand it anyway.

22:13:19 <Ilari> Hmm... Are there any esolangs with non-euclidean IP space topology?
22:14:04 <cpressey> AnMaster: you're right, __slots__ is what I'm looking for. I'll probably get into arguments with other engineers though, about how "inflexible" it makes things.
22:14:33 <cpressey> That's what I mean about culture :)
22:14:34 <AnMaster> cpressey, there is also a performance argument for it iirc
22:14:35 <lament> Ilari: i realize it's not an esolang, but in what sense is the IP space topology euclidean?
22:15:10 <AnMaster> cpressey, being stored in object (with an offset) rather than in a dict
22:15:59 <cpressey> I don't think Euclid had much to say about topology
22:17:23 <Ilari> non-euclidian topology meaning space that's not topologically equivalent to euclidean space.
22:18:04 <Ilari> Including such things as toroidial spaces...
22:18:46 <cpressey> Ilari: Oh. Well, Befunge, then?
22:18:53 <Ilari> Ah yes, befunge...
22:19:20 <Ilari> But are there esolangs with even more "exotic" IP spaces than Befunge?
22:19:53 <cpressey> I would also tend to agree with lament that most "non-esoteric" languages have a highly non-euclidean "space" for IPs. I'm not a mathematician so I can't describe it...
22:21:20 <lament> oh yeah, duh, befunge is a good example too
22:21:55 <Ilari> MissPiggy: Instruction pointer.
22:22:07 <cpressey> Program Counter for all you 6502 fans out there
22:24:13 <fizzie> I'm sure 6502 isn't the only one who calls it that; the corresponding register is called PC for Z80 too, for example.
22:24:21 <AnMaster> cpressey, what about a möbius (sp?) befunge
22:24:55 <AnMaster> or to extend to 3d: klein befunge
22:25:00 <Ilari> Well, simpler discrete spaces can be described by describing each axis: n positions (linear), n positions (360 degree symmetry), n positions (720 degree symmetry), half-infinite, infinite.
22:25:05 <olsner> "IP" sometimes stands for IntraProcedural register (i.e. a temp register)
22:26:44 <Ilari> It starts to get really exotic when space can't be described as cartesian product of those axis types.
22:27:32 <Ilari> AnMaster: Spaces containing "wormhole"-type constructs.
22:27:54 <AnMaster> Ilari, right now I'm imagining a trefunge with wormholes
22:28:15 <AnMaster> and I imagine it could be done with a fingerprint WORM
22:28:19 <Ilari> Actually, one only needs two dimensions to have wormholes.
22:28:22 <olsner> "a trefunge with wormholes" sounds like an infested mushroom
22:28:40 <fizzie> Funge-98's ; command could be considered wormholey.
22:28:57 <AnMaster> fizzie, it is more like "skip to matching"
22:29:22 <AnMaster> rather this would mean that touching a given space would dump you somewhere else, possibly going in a different direction
22:29:24 <fizzie> Well, it's traversed in no time, so it's not like other instructions.
22:29:45 <AnMaster> so: like one other instruction
22:30:00 <fizzie> Space is not an instruction.
22:30:42 -!- tombom_ has quit (Quit: Leaving).
22:30:44 <Ilari> Wormhole would take time to transverse, the wormhole has interrior and it is part of space.
22:31:04 <AnMaster> this would be one cool befunge fingerprint
22:31:16 <Ilari> The wormhole interrior space would be something like linear x 360 degree.
22:31:24 <fizzie> Given how much ; and empty space are alike, it wouldn't feel too wrong to describe ; as just a notation about the 'shape' of the IP space.
22:31:27 <AnMaster> (meaning it might be implemented in efunge, but never cfunge)
22:31:35 <AnMaster> Ilari, couldn't there be wormholes in the wormhole?
22:31:42 <cpressey> You could have a non-commutative geometry where going north then south is not guaranteed to put you back where you were.
22:32:14 <Ilari> AnMaster: Could be possible.
22:32:31 <Ilari> fizzie: Jumps initiated by ; follow space geometry.
22:33:01 <AnMaster> wouldn't that bending of the funge-space-time slow down ips traveling near the wormhole?
22:33:03 <Ilari> fizzie: Or what would happen in current funges if one used ; to jump against space boundary?
22:33:14 <AnMaster> so as to disrupt the round-robin threading
22:33:27 <AnMaster> meaning they run possibly at a fractional overlap
22:34:03 <Ilari> AnMaster: They don't slow down. Wormhole space is discretized and IPs move following geometry when inside wormhole.
22:34:04 <fizzie> Ilari: But it's not "initiated" by ;, because you don't execute the ; -- instead the IP just moves somehow "past" the locations that contain other instructions, as if by taking some other route.
22:34:21 <AnMaster> Ilari, hm. but would it be a sharp edge to the wormhole?
22:34:45 <AnMaster> fizzie, what? sounds like bullshit to me
22:35:07 <AnMaster> fizzie, also, how did you implement it? ;P
22:35:12 <fizzie> AnMaster: To quote the spec: "; is truly ethereal; like space, it cannot ever be truly executed, in the sense of it taking up a tick and doing something."
22:35:18 <fizzie> See, it's not an instruction you can execute.
22:35:24 <AnMaster> fizzie, "in the sense that..."
22:35:34 <fizzie> Yes, in the sense that means something.
22:35:41 <Ilari> fizzie: Really, what happens if IP hits ; and there isn't another before IP space "edges" are hit?
22:35:53 <cpressey> Ilari: It wraps around to the nearest matching ;
22:36:08 <Ilari> Yeah. Though so, which means it follows space geometry.
22:36:39 -!- kar8nga has quit (Remote host closed the connection).
22:37:11 <Ilari> With wormholes, ; would go into wormhole (possibly finding pairing ; inside wormhole).
22:37:12 <augur> cpressey: you can make a scheme like language, just employ some interesting new concept
22:37:40 <cpressey> So (my Befunge is really rusty so bear with me): 11.;.@ would print two 1's, and stop. It should skip right around the ; as if it wasn't there, I think.
22:37:45 <AnMaster> which is why I think WORM would be cool
22:37:56 <AnMaster> but I can only think of this with sharp edges
22:38:45 <AnMaster> not like the smooth bending in towards the hole like in http://en.wikipedia.org/wiki/File:Worm3.jpg
22:38:48 <Ilari> Probably easiest way is to have wormhole edge boundaries be closed and of same length. Then the circumference of interrior matches circumference of edge.
22:39:11 <Deewiant> If a program contains only one ; (and never modifies space to place another one), it's equivalent to the same program with the ; replaced by a space
22:39:25 <cpressey> augur: Unfortunately my new concept would only be "design a language which doesn't suck" :)
22:39:40 <fizzie> Ilari: I really have to disagree about this; I personally think you can still describe ; as a notational device you use to describe the particular non-euclidian behaviour of the IP space, when you have to express it in a discrete 2D matrix. If you have a matching pair of ;s in the code, it means the shape of the space is such that when you move with the right direction, you move directly from one ; to the other. How's that sort of space "euclidean" to you?
22:39:44 <AnMaster> Ilari, yes, as a cylindrical hole I guess
22:40:12 -!- Pthing has quit (Remote host closed the connection).
22:40:17 <AnMaster> which would give a limited size cylindrical funge-space inside
22:41:11 <fizzie> (Come to think of it, I don't suppose any discrete space is very euclidean.)
22:41:13 <Ilari> There are actually two types of holes, ones that have no internal crossing (IP reverses direction when transversing) and internally crossed holes (IP keeps direction).
22:42:03 <Ilari> Also, there is length of hole. Smallest possible length is 1, which has no interrior space at all (edges of wormhole are adjacent).
22:42:12 <AnMaster> Ilari, hm, as in twisted half a turn?
22:42:57 <cpressey> augur: I still might do it. Even though it will almost certainly also suck.
22:43:00 <AnMaster> 1 would have one cell worth of length
22:44:40 <Ilari> Actually, circumference of hole interrior would have to match number of configurations that hit hole edge (and not just circumference of edge).
22:45:10 <cpressey> I tend to agree with fizzie's view -- ; are bit like wormholes. But they're not fixed wormholes. Where the IP ends up depends entirely on its delta.
22:45:12 <AnMaster> it would have to follow the quantized form I guess
22:45:37 <AnMaster> Ilari, not sure how it would work for non-cardinal ips
22:45:52 <Ilari> AnMaster: Befunge has those too?
22:46:10 <AnMaster> Ilari, befunge-98 does. You can have a delta of (34,2) or such if you want to
22:46:29 <Deewiant> -93 doesn't have ; so it's not that relevant here anyway
22:46:33 <AnMaster> or even (0,0) but that is fairly useless
22:47:09 <fizzie> Deewiant: Given that those guys view ; as just another instruction, I'd say ; is also not relevant; certainly you can imagine -93 with wormholes.
22:47:46 <Deewiant> Sure, you can imagine whatever you like, I'm just talking about what's already there. :-P
22:48:08 <Deewiant> Orthogonal with wormholes for all I care
22:48:23 <AnMaster> Ilari, I can't figure out how a non-cardinal delta would move through a worm hole
22:48:31 <Ilari> All I'm saying is that ; would follow underlying geometry, whatever it is.
22:48:56 <Ilari> And then there's problem of determining if it even _hit_ a hole...
22:48:56 -!- augur has quit (Ping timeout: 272 seconds).
22:49:17 <AnMaster> hm. if it is in it's path, then shouldn't it have done so?
22:49:21 <cpressey> This is where the whole idea of "any topology you want" breaks down
22:49:30 <AnMaster> this means figuring out if it passed it, it might have just touched the edge
22:49:35 -!- FireFly has quit (Quit: Leaving).
22:49:47 <AnMaster> which means floating point arithmetics or such
22:50:05 <AnMaster> and then it might not even hit a whole number cell afterwards
22:50:55 <cpressey> Even a hex-net Befunge would need a completely different set of semantics.
22:51:03 <Ilari> If one would take non-cardinal directions as quantized line that's traced, then that would enable computing where IP ends up in presence of wormholes.
22:51:10 <cpressey> Well, not COMPLETELY. But pretty different.
22:51:28 <cpressey> And I guess it would be triangle-net. But whatever.
22:52:19 <AnMaster> Ilari, would it end up neatly in an integer cell?
22:52:23 <Ilari> Since that would mean that all deltas could be broken down to cardinal IP movements.
22:53:14 <AnMaster> cpressey, would it really need different rules apart from changing <>^v to something more relevant?
22:53:37 <cpressey> AnMaster: how do you do g and p?
22:53:56 <cpressey> You end up mapping Cartesian coordinates over the thing
22:54:02 <AnMaster> cpressey, well, they need to be changed the same way as x
22:54:41 <AnMaster> then you could figure out "what delta would this cell have starting at the origin"
22:55:31 <cpressey> AnMaster: kinda, but I think it proves my point that it would be a significant change to the semantics
22:56:00 <Ilari> The smallest possible wormhole would have 1x1 ends. And would have interrior diameter of 4.
22:56:10 <Ilari> s/diameter/circumference/
22:56:20 <cpressey> All my ideas for how Funge could be "improved" after 98 were too radical, anyway :)
22:58:08 <fizzie> Ilari: All I'm saying is that I like more the point of view where ; is not an instruction that can "follow underlying geometry", but instead a notation about the space the IP moves in. Of course you can get similar results by using a simpler "underlying geometry" -- a discrete 2-dimensional thing with funky wrapping -- and adding "jump" instructions, and I guess you could try some sort of "simplest geometry wins" rule for justifying that the Funge-98 space is n
22:58:09 <fizzie> ot "exotic" enough, but... well, meh. I doubt this is going anywhere. Must be away.
23:01:06 <Ilari> Could the problems with non-cardial IPs solved by making corners correspond to line in interrior space? That would mean that 1x1 hole would have interror circuference of 8...
23:02:06 <fizzie> If you map (integer) cartesian coordinates over a hex-grid or so and define x, g, p, and everything else that takes numeric coordinates, using those, I think what you're left with is just the usual sort of Funge-98 except with some special "movement modes" corresponding to the the diagonal-movement-to-neighbor-cells, which you can't even describe using a single (x, y) coordinate pair delta value.
23:03:01 <cpressey> fizzie: I agree, and I agree that's a reason to avoid doing that mapping if at all possible.

23:03:54 -!- cheater2 has joined.
23:05:44 <cpressey> I seem to remember one proposal that works in any topology. Instead of a delta, you have a path, which is a list of directions. Similar to how arrows work in Hunt the Wumpus.
23:06:13 -!- BeholdMyGlory has quit (Remote host closed the connection).
23:06:43 <cpressey> So instead of (3,3), you have ">>>^^^" (or ">>^^>^" or ">>>>^^^^<v" or any of the other infinite number of possibilities for that.)
23:07:28 <cpressey> That extends to triangle-nets or whatever else, and solves the question of "When did we hit this wormhole?"
23:08:13 <cpressey> It wasn't a popular idea at the time, though.

23:09:30 -!- Wareya has joined.
23:19:18 <Ilari> Actually, I think I came up with way to define behavour of wormholes with non-cardinal deltas (and it would solve also some other problems with wormhole coordinate compuation), but would seriously screw up if there was wormhole that had one end in normal space and one end in interror space of another wormhole.
23:21:23 <Ilari> More precisely, it would demand that wormhole ("level 1 wormhole") that has one end in normal space, also has the other end in normal space, wormhole ("level 2 wormhole) that has one end in level 1 wormhole interror space has the other end also, etc...
