| 00:07 | <@gnolam> | ... and I've succeeded too well. |
| 00:07 | <@gnolam> | I've been staring at a spinning cube for 15 minutes now. |
| 00:08 | <@Derakon[work]> | Heh. |
| 00:09 | <@gnolam> | In my defense, bump mapped hieroglyph are quite pretty. ^-^ |

| 00:51 | < Rhamphoryncus> | Tarinaky: *reads way back* If it would help I could try to convince you Python's whitespace is a good thing ;) |
| 00:54 | < Tarinaky> | You can if you want. I mostly just l like the idea of an interpretter for me to test out new functions and classes without having to edit my main code. I tried a package for creating python modules out of C++ code but it didn't work so I just use gdb instead. |
| 00:55 | < Tarinaky> | Which is a bit hackish but is probably more useful because then I can immediately step through the code if there is a problem. |
| 00:56 | < Rhamphoryncus> | Yeah, if you're just using it for testing you won't really appreciate the language |
| 00:58 | < Rhamphoryncus> | btw, it's possible to get gdb with python scripting :) |
| 00:58 | < Rhamphoryncus> | (as opposed to using gdb to debug python) |
| 00:59 | < Tarinaky> | Rhamphoryncus: It probably is. But I still have the problem that the code the tool generates might not be the same code that I actually want to use. |
| 00:59 | < Tarinaky> | I like braces for block delimiting and stuff. |
| 00:59 | < Rhamphoryncus> | You misunderstand. I mean gdb itself using python internally as a scripting language |
| 01:00 | < Rhamphoryncus> | And you don't like indenting your code? |
| 01:00 | < Tarinaky> | I don't like indenting in my interpretters. |
| 01:00 | | Derakon[AFK] is now known as Derakon |
| 01:00 | < Rhamphoryncus> | So stop treating python like an interpreter. Treat it as a serious language |
| 01:01 | <@Vornicus> | I are serious coder. Python are serious language. |
| 01:01 | <@Vornicus> | :P |
| 01:01 | < Rhamphoryncus> | heh |
| 01:01 | < Tarinaky> | Okay. As a serious language I don't really see what it has that I want. |
| 01:02 | < Rhamphoryncus> | Readability? |
| 01:02 | < Tarinaky> | I don't have any trouble reading my code as it is. |
| 01:02 | <@Derakon> | Not requiring makefiles? |
| 01:03 | <@Vornicus> | An absurdly huge standard library that's pretty well documented to boot? |
| 01:03 | < Tarinaky> | I'll grant not having to compile is 'nice' but I don't mind makefiles and C++ has a huge standard library that's well documented >.> |
| 01:04 | < Rhamphoryncus> | Python code will typically be substantially shorter than C/C++ code, which is part of its readability |
| 01:04 | <@Derakon> | Weren't you earlier complaining about having to write makefiles by hand? |
| 01:04 | <@Derakon> | Oh, also: not having to muck about with memory management. |
| 01:04 | < Tarinaky> | No. I was under the impression that it was bad form to write them by hand. |
| 01:05 | < Tarinaky> | >.< my main problem with python is it's not C++. This is a completely irrational stand to take and I understand this. |
| 01:05 | < Rhamphoryncus> | Aye, but I can accept that argument :) |
| 01:06 | < Tarinaky> | I like Java more because it's more like C++. |
| 01:06 | < Tarinaky> | But Java apps take an age to start which annoys me far more than compiling does. |
| 01:07 | < Tarinaky> | s/compiling/portability |
| 01:07 | < Tarinaky> | *the portability |
| 01:08 | | * Vornicus does wonder why java apps still take so long to start in most places. |
| 01:08 | < Tarinaky> | I -think- it's just-in-time compilation. |
| 01:08 | < Rhamphoryncus> | Vornicus: part atleast is the JIT takes a while to warm up |
| 01:08 | < Tarinaky> | Which could probably be solved with some sort of caching I think. |
| 01:09 | < Tarinaky> | But then it wouldn't be just-in-time compiling. |
| 01:10 | <@Vornicus> | It took forever to start up before and that wsan't jit. |
| 01:10 | < Tarinaky> | Initialising the virtual machine? |
| 01:14 | < Tarinaky> | Of course. Before JIT there was the problem that -everything- was slow. So it might be that they solved one problem by making another >.< |
| 01:15 | < Rhamphoryncus> | yeah, wouldn't surprise me if the VM is the worst of it |
| 01:15 | < Rhamphoryncus> | If you do a dummy program then the JIT isn't an issue |
| 01:16 | < Tarinaky> | It's been a while since I touched java. I never really got into it. |
| 01:17 | < Rhamphoryncus> | wikipedia attributes it to the class library |
| 01:17 | < Rhamphoryncus> | and the IO of such |
| 01:19 | < Tarinaky> | Sounds about right. |

| 03:43 | | * ToxicFrog upreads |
| 03:43 | <@ToxicFrog> | Oh, Tar left. Aah well. |
| 03:45 | <@Derakon> | loc.add(directionToVectorMap[direction].multiply(-depth)).toRealspace() |
| 03:45 | <@Derakon> | I think I may be piling a bit too much into that line... |
| 03:52 | < Rhamphoryncus> | Only slightly. loc.add(foo) should return None ;) |
| 03:52 | < Reivthia> | Have I mentioned how much I love this channel? >_> |
| 03:52 | <@Derakon> | Rhamphoryncus: Vector2Ds are meant to be immutable. |
| 03:53 | <@Derakon> | Among other things, this excuses using them as keys in dictionaries. |
| 03:53 | < Rhamphoryncus> | oooh, so it returns a copy. Sorry, couldn't tell :) |
| 03:54 | < Rhamphoryncus> | Is it possible to use the + operator? (loc + directionToVectorMap[direction].multiply(-depth)).toRealspace() |
| 03:54 | | * Rhamphoryncus wonders if multiply should be renamed scaled |
| 03:54 | <@Derakon> | When I wrote the Vector2D class, I didn't feel like looking up the magic names for the +, -, *, etc. operators. |
| 03:54 | <@Derakon> | And at this point, it has its tentacles into everything, so while I could change it, it'd be a chore. |
| 03:54 | < Rhamphoryncus> | __add__, __sub__, __mul__, __truediv__ |
| 03:55 | | * Derakon nods. |
| 03:56 | <@Derakon> | I hope that __truediv__ got renamed in Python 3. |
| 03:57 | < Rhamphoryncus> | 'fraid not. It used to be __div__ but got separated into __floordiv__ and __truediv__ |
| 03:58 | <@Derakon> | Tsk. |
| 03:58 | < Rhamphoryncus> | The old / operator got split into // and /. The latter only if you use from __future__ import division |
| 03:58 | <@Derakon> | So wait, in Python 3, unless I do "from future import division", I can't use the / operator? |
| 03:59 | < Rhamphoryncus> | err sorry, in 2.x you use that to switch the / operator |
| 03:59 | < Rhamphoryncus> | 3.0 does it by default |
| 03:59 | <@Derakon> | Ahh, okay, that meshes better with what I'd heard. |
| 03:59 | < Rhamphoryncus> | So 1/2 returns 0.5 rather than 0 |
| 04:03 | <@Derakon> | Ahh, no wonder Jetblade wasn't writing mapfiles. |
| 04:03 | <@Derakon> | def writeMap(self, name = None): |
| 04:03 | <@Derakon> | return |
| 04:03 | < Rhamphoryncus> | heh |
| 04:06 | <@Derakon> | And now I remember why I did that. For testing purposes, I was shoehorning the new furniture objects into the scenery tree, but that breaks when it comes time to write the scenery to file. |
| 04:06 | <@Derakon> | Since furniture objects aren't scenery objects. |

| 13:08 | < Tarinaky> | Someone suggested a tool called makedepends last night. I've discovered that although my system doesn't appear to have it g++ has some flags that performs the same behavior. I am, however, having trouble working out how I'm meant use this. I'm having a look on google but I'm not really sure what I'm looking for. |

| 13:45 | < Tarinaky> | What the fuck. I've not changed a source file and now it's refusing to compile. o.o What's worse is said sourcefile is copied out of a text book and I -know- it worked last time I looked at it. |
| 13:45 | < Tarinaky> | I know the packages haven't changed because I've been watching what I update recently. |
| 13:46 | < Tarinaky> | This is incredibly frustrating. |
| 13:46 | <@TheWatcher> | What's the error you're getting? |
| 13:46 | < Tarinaky> | Ah. >.< Figured out what I was doing wrong. |
| 13:57 | < Tarinaky> | Okay. So I'm trying to modify an example from a text-book of a yacc specification so that the parser accepts dice expressions (ie '3d6' 'd8+2' etc...) but I'm getting a shift/reduce conflict and I'm not exactly sure why or how to resolve it. |
| 14:04 | | * TheWatcher can not, alas, assist - has always made a complete pig's ear of yacc stuff |
| 14:04 | | * Tarinaky wtfs as the example has, once again, stopped working for no discernable reason. |
| 14:08 | < Tarinaky> | As best as I can tell what I have on my hard-drive is character-for-character identical to the example and what I had before and it's suddenly stopped working again except with no error o.o |
| 14:09 | < Tarinaky> | This is seriously arcane. |

| 14:40 | <@ToxicFrog> | <-- |
| 14:41 | < Tarinaky> | I was trying to modify an example from a book of a simple calculator parser. It stopped working (it'd just silently fail to do anything). I reverted it back to the code listing in the book but it's still silently refusing to do anything. |
| 14:41 | < Tarinaky> | It's compiling without error though. It's just not working and I don't know why. http://tarinaky.pastebin.com/m6faac4a7 |
| 14:44 | | NSGuest-2373 is now known as SouthernMyst |
| 14:45 | <@ToxicFrog> | Silently failing at what stage? |
| 14:46 | <@ToxicFrog> | Also, sanity check: you're remembering to re-run lex and yacc after reverting those files? |
| 14:46 | <@ToxicFrog> | In that order? |
| 14:47 | < Tarinaky> | I re-ran lex and yacc. |

| 15:01 | | * Tarinaky is back. |
| 15:02 | < Tarinaky> | ToxicFrog: Where does that line go? |
| 15:03 | <@ToxicFrog> | Start of first.l |
| 15:03 | <@ToxicFrog> | If you have your own yywrap(), you don't need it |
| 15:03 | <@ToxicFrog> | And if you don't have either, you'll know because flex will error. |
| 15:04 | < Tarinaky> | I have exactly what is in those two files and whatever the libraries come with. |
| 15:04 | <@ToxicFrog> | Where's your main()? |
| 15:04 | <@ToxicFrog> | Or are you using the one provided by libyacc? |
| 15:04 | < Tarinaky> | I was under the impression (both from the text and it having worked before) that if I didn't provide one it'd fall back on one in library somewhere. |
| 15:06 | <@ToxicFrog> | Yes, it will. |
| 15:06 | <@ToxicFrog> | It works here using the library main, too |
| 15:07 | < Tarinaky> | I just tried to use it with noyywrap and it made no difference. |

| 15:08 | <@ToxicFrog> | Yeah, I didn't think it would; I suspect you have a build system failure somewhere |
| 15:09 | <@ToxicFrog> | Either you aren't reprocessing/recompiling something that you should be, or the files you're using as input aren't the ones you actually modified |
| 15:09 | | AnnoDomini [AnnoDomini@Nightstar-29132.neoplus.adsl.tpnet.pl] has joined #Code |

| 15:14 | < Tarinaky> | xD |
| 15:14 | <@ToxicFrog> | o.O |
| 15:15 | < Tarinaky> | This is seriously arcane. |
| 15:15 | <@ToxicFrog> | That shouldn't make any difference! |
| 15:16 | < Tarinaky> | Ahah! |

| 15:16 | < Tarinaky> | 2+6 |
| 15:16 | < Tarinaky> | Spot the difference :3 |
| 15:16 | <@ToxicFrog> | ...I'm using flex, you're using lex? |
| 15:16 | < Tarinaky> | Nope. |
| 15:16 | <@TheWatcher> | -lfl -ly v -ly -lfl |
| 15:17 | < Tarinaky> | Yup. |
| 15:17 | < Tarinaky> | I didn't think that mattered :s |
| 15:17 | <@ToxicFrog> | ...I note mine works without -lfl, too |
| 15:17 | <@ToxicFrog> | But putting -lfl in front of -ly causes it to fail |
| 15:18 | < Tarinaky> | You have %option noyywrap. At no stage did I actually try it without -lfl >.< I didn't realise I didn't need -lfl with noyywrap. |
| 15:18 | <@ToxicFrog> | Aah |
| 15:19 | < Tarinaky> | I still don't understand why -lfl -ly doesn't work though. But at least I know what the problem is >.> |
| 15:22 | <@gnolam> | For GCC, linking order matters. |
| 15:22 | < Tarinaky> | I'd ask why, but is it a case of magic? |
| 15:22 | <@ToxicFrog> | And both libfl and liby provide main() |
| 15:22 | < Tarinaky> | Ahh. |
| 15:22 | < Tarinaky> | That makes sense then. |
| 15:23 | <@ToxicFrog> | (check this with: nm /usr/lib/libfl.a) |
| 15:23 | <@ToxicFrog> | If libfl is linked first and you don't have your own main(), the first one gcc sees will be the one provided by libfl, which is a wrapper around yylex() |
| 15:23 | <@gnolam> | But in the general case, because the GCC devs are too lazy/the codebase is too complicated to properly account for dependencies. |
| 15:24 | <@gnolam> | Say what you want about MSVS, but linking is something it Does Right (TM). |
| 15:24 | <@ToxicFrog> | This has not been my experience~ |
| 15:26 | | * Tarinaky shrugs. I have no interest in a windows vs linux argument >.< |
| 15:26 | | * Tarinaky uses linux because it comes with more stuff. |
| 15:27 | <@ToxicFrog> | Well, it's really a gcc vs msdev argument, since you can run gcc on windows and you can at least run the msdev backend on linux (via wine) |
| 15:27 | < Tarinaky> | I'm informed that the ms compiler is the best compiler for Windows (in terms of code efficiency). I don't know if that's changed any since I heard that. |
| 15:29 | <@gnolam> | MSVS is also able to do cross-module inlining, which is another reason I consider its linking right and GCC wrong. But mostly I'm sick and tired of GCC linking voodoo (try to compile, get errors, switch the order of some libraries at random, behead black chicken, rinse, repeat). :P |
| 15:30 | <@ToxicFrog> | Anyways, regarding conversations yesterday - if you like the interpreter and high-levelness of python but don't care for the whitespace sensitivity, consider playing with Lua. It doesn't have python's huge set of libraries, but takes a lot of language ideas from it (and Scheme and Javascript, mostly) and has a more relaxed syntax. |

| 17:38 | < Tarinaky> | git is a bit arcane and I have no idea if it's actually doing what I expect it to be doing or not >.< |
| 17:39 | < Derakon[work]> | Heh. |
| 17:39 | < Derakon[work]> | The only commands I've used on hg are add, remove, revert, commit, update, and push. |
| 17:39 | < Derakon[work]> | Oh, and status and diff, of course. |
| 17:40 | < Tarinaky> | I've never used it before. |
| 17:41 | < Derakon[work]> | What source control have you used? |
| 17:41 | < Tarinaky> | mv. |
| 17:41 | < Tarinaky> | mkdir and mv. |
| 17:41 | < Tarinaky> | :p |
| 17:41 | < Derakon[work]> | Tsk. |
| 17:41 | < Tarinaky> | Well... technically I mean cp >.< |
| 17:42 | < Tarinaky> | But w/e. You get the joke. |
| 17:42 | < Derakon[work]> | Okay, the way git and other distributed version control systems work, then, is that you basically get a copy of the entire repository, complete with history on changes made to each file. |
| 17:42 | < Derakon[work]> | So say I check in helloworld.py one day. |
| 17:42 | < Tarinaky> | I know the theory. |
| 17:42 | < Derakon[work]> | Okay. |
| 17:42 | < Tarinaky> | I've just... Never actually used one. |
| 17:42 | < Derakon[work]> | It's hard to know sometimes. |
| 17:42 | < Tarinaky> | git log shows that at least my commit comments are being added. |
| 17:43 | < Tarinaky> | But I've no idea if the actual files/deltas are in there. |
| 17:44 | | You're now known as TheWatcher[afk] |
| 17:46 | < Derakon[work]> | Tarinaky: well, clone your git repo to another directory and see what you get. |
| 17:47 | < Tarinaky> | I tried checking out a file (after renaming it) and it seems to have worked as expecte. |
| 17:47 | < Tarinaky> | *expected. |
| 17:48 | < Tarinaky> | It's just I won't trust that it's working until I have a serious situation where I need it. And by that point it'll be too late >.> |
| 17:49 | < Derakon[work]> | No, I mean make a clone of your repo. |
| 17:49 | < Tarinaky> | What exactly do I need to copy/ |
| 17:50 | < Derakon[work]> | For example, if your repo's in ~/proj/project1, make a clone of it in ~/proj/project1-test and see if the file is there. |
| 17:50 | < Tarinaky> | The .git/? |
| 17:50 | < Derakon[work]> | Don't use cp. |
| 17:50 | < Derakon[work]> | Use its checkout command |
| 17:50 | < Derakon[work]> | Basically you're going to say "Make a git repo by taking the files from this other git repo". I don't know git's commands so I can't tell you the proper invocation. |
| 17:50 | < Tarinaky> | is-git-working>>git checkout |
| 17:50 | < Tarinaky> | fatal: Not a git repository (or any of the parent directories): .git |
| 17:51 | < Derakon[work]> | I believe what you want is "git clone old/repo/path new/repo/path" |
| 17:53 | < Tarinaky> | Ahah. |
| 17:53 | < Tarinaky> | How do I delete the clone? |
| 17:53 | < Derakon[work]> | rm -r its directory. |
| 17:53 | < Tarinaky> | I see. |
| 17:53 | < Tarinaky> | Cool I guess. |
| 17:53 | < Derakon[work]> | I do this step anytime I think I'm ready to push my Jetblade changes to the Google Code repository, just to make certain there aren't any files I forgot to include. |
| 17:54 | < Derakon[work]> | It's very handy for comparing what you think the repo looks like to what it actually looks like. |
| 17:54 | < Tarinaky> | There -must- be a command that outputs a directory structure to stdout as text. |
| 17:55 | | * Tarinaky has to leave for food. |
| 17:55 | < Derakon[work]> | Um, "find ."? |

| 18:12 | < Tarinaky> | I don't understand. |
| 18:12 | < Derakon[work]> | You want to know what your directory structure looks like? |
| 18:12 | < Derakon[work]> | Run "find ." from the commandline. |
| 18:14 | < Tarinaky> | Oh. I meant the directory structure that git is storing. |
| 18:14 | < Tarinaky> | But that's the kind of output I mean. |

| 18:24 | < Tarinaky> | I'm trying to find some information on using flex/bison with C++. There's just enough floating on google to make it look like it can be done but not enough for me to know how it's done >.< |

| 18:33 | <@ToxicFrog> | murr? |
| 18:34 | <@ToxicFrog> | Tarinaky: what do you mean by "the directory structure that git is storing"? |
| 18:34 | <@ToxicFrog> | You want to look at the contents of a commit without checking it? |
| 18:34 | <@ToxicFrog> | Er, without checking it out? |
| 18:34 | <@ToxicFrog> | Or you want to look at git's internal storage structures? |
| 18:34 | <@ToxicFrog> | Or what? |
| 18:36 | < Tarinaky> | Looking at the contents of [can't think the right word] without doing a git clone. |
| 18:36 | < Tarinaky> | Anyway. It doesn't matter. |
| 18:36 | < Tarinaky> | repository? |
| 18:36 | < Tarinaky> | Meh. |
| 18:36 | <@ToxicFrog> | gitk --all? |
| 18:36 | <@ToxicFrog> | That will show you all the stored revisions and let you look at the comments and deltas for them |
| 18:36 | <@ToxicFrog> | (GUI, though) |
| 18:37 | <@ToxicFrog> | There are also options to git log that will show you lists of changes files, or even complete diffs |
| 18:38 | <@ToxicFrog> | And if you want to see what a given commit has stored without checking it out, git ls-tree -r <commit> |
| 18:38 | < Tarinaky> | I see. Thanks. |
| 18:39 | < Tarinaky> | I was wondering if you knew anything about using code generated by flex/bison in a C++ project? |
| 18:39 | <@ToxicFrog> | don't~ |
| 18:39 | <@ToxicFrog> | Well, not really |
| 18:40 | <@ToxicFrog> | I tried it once, it didn't go well, but then, I hate C++ |
| 18:40 | <@ToxicFrog> | I know flex and bison have some support for it |
| 18:40 | <@McMartin> | You may have to do the extern "C" stuff |
| 18:40 | < Tarinaky> | Same. There's just enough on google to suggest it can be done without actually giving any indication of how to do it >.< |
| 18:41 | < Tarinaky> | And from what I can gleam everyone seems to be doing it in very different ways. |
| 18:41 | <@ToxicFrog> | Well, reading what the flex/bison manuals have to say about C++ support and the --c++ option may be a good start |
| 18:41 | <@ToxicFrog> | http://flex.sourceforge.net/manual/Cxx.html#Cxx |
| 18:42 | < Derakon[work]> | grep -E "def|class" sebH.py | wc -l |
| 18:42 | < Derakon[work]> | 135 |
| 18:42 | < Derakon[work]> | Aaaargh |
| 18:48 | <@McMartin> | ^def, surely |
| 18:49 | < Derakon[work]> | That won't catch defs inside classes. |
| 18:49 | < Derakon[work]> | Or defs inside other defs. |
| 18:49 | <@McMartin> | Mm |
| 18:49 | < Derakon[work]> | (Similarly, ^class won't catch classes inside defs, which I know he's done) |
| 18:50 | | * McMartin is mostly concerned about identifiers with "def" in it. |
| 18:50 | < Derakon[work]> | Sufficiently uncommon as to be noise for the purposes of that survey. |
| 18:57 | <@ToxicFrog> | 135 didn't sound unreasonable until I realized there was no -r on that grep >.< |
| 18:59 | < Derakon[work]> | Yeah, that's a 1686-line Python file, and as near as I can tell the functions have little to do with one another. |
| 18:59 | < Derakon[work]> | I suspect the H stands for Helper. |
| 19:00 | | * Derakon[work] hacks up the code enough to get it to where it doesn't crash on its own right at the start. |
| 19:01 | < Tarinaky> | ...In C is int function (void) a synonym for int function () or is this allowed because of the weaker type checking in C? |
| 19:02 | < Derakon[work]> | Instead, I get this: http://derakon.dyndns.org/~chriswei/temp2/lappyui.png |

| 19:41 | < Rhamphoryncus> | Tarinaky: regarding C function declarations, it's actually the other way around. int function (void) is the explicit declaration and int function () is the vague one |

| 19:41 | < Rhamphoryncus> | I'm using the wrong words |

| 19:42 | < Rhamphoryncus> | There's a specific meaning for () |

| 19:45 | < Rhamphoryncus> | gah |
