| 00:08 | <@Tarinaky> | RichyB: I don't know how to do a memory buffer with PyGlet/OpenGL... |
| 00:08 | <@Tarinaky> | I'm not even sure if you can. |
| 00:09 | <&McMartin> | OpenGL has extensions for render-to-texture and the DX10-equivalent levels (which most OpenGL libraries don't expose by default, because OpenGL) have render-to-texture capability explicitly. |
| 00:10 | < RichyB> | You can render from opengl or direct3d into a texture. |
| 00:10 | <@Tarinaky> | How? |
| 00:10 | <@gnolam> | Since... err... 3.0?, said extensions are no longer extensions but in core. |
| 00:11 | < RichyB> | You can *definitely* copy a memory buffer to a texture; that's how loading textures from disk works. |
| 00:11 | <&McMartin> | I would not lay heavy odds on PyGlet supporting 3.0. |
| 00:11 | <@gnolam> | The "easy" way is to use FBOs. |
| 00:11 | < RichyB> | In OpenGL, that's done with FrameBufferObjects. |
| 00:11 | < RichyB> | Specifically, redner to texture is done with FBOs. |
| 00:12 | <&McMartin> | Yeah, I mean, really, the problem here is "turn raster image to texture" |
| 00:12 | <&McMartin> | that's a *lot* easier |
| 00:12 | <&McMartin> | That's TexImage2D |
| 00:12 | | * gnolam reads up properly. |
| 00:13 | <@gnolam> | Ah, seems to be a question about texture /management/. |
| 00:13 | <&McMartin> | The best solution may be "find a PyGlet-based extension that does all the GUI spiders, use that", but I don't know the ecosystem well enough to opine |
| 00:13 | <@Tarinaky> | There isn't one. |
| 00:14 | <@Tarinaky> | I've spent the last month umming and arring trying to find something, anything, in the ecosystem for this and I can't :/ |
| 00:14 | | * McMartin nods |
| 00:14 | <&McMartin> | >_< |
| 00:15 | <&McMartin> | Anyway, yeah, if you want bitmappy buttons of varying size, the nine-texture trick is basically how Qt does custom windows, and I expect it generalizes. |
| 00:15 | <&McMartin> | You can drop nine to three if the buttons are constant height or constant width but not both, and you can drop three to one if it's both. |
| 00:15 | <&McMartin> | But your questions lead me to believe it is not both. :) |
| 00:16 | <@Tarinaky> | Any advice on either texture management or actually drawing before I go get a coffee? |
| 00:17 | <&McMartin> | I'm basically out of tricks on this point, and I don't know PyGlet at all, just some very casual use of OpenGL through C and C++. |
| 00:17 | <@Tarinaky> | Okay. |
| 00:19 | <&McMartin> | If you aren't going totally nuts, though, generating nine 32x32 textures or whatever and having all your buttons use them is not going to blow out any GPUs you target. |

| 01:09 | <@gnolam> | Tarinaky: what part of texture management is it that you need help with? |
| 01:10 | <@Tarinaky> | I don't know what I'm doing. |
| 01:11 | <@gnolam> | Well, at what level? Is it "how do I even get a texture into this thing?" or is it "how should I handle having hundreds of different textures and dividing the responsibility for them"? |
| 01:11 | <@Alek> | http://www.youtube.com/watch?v=OXx1qxH247k |
| 01:11 | <@Tarinaky> | I think I understand how to actually apply a texture to a Quad. It's mostly of the "what should the textures look like/how should I make them" nature. |
| 01:13 | <@gnolam> | For a nine-texture resizeable widget thingy? |

| 02:04 | <&Derakon> | ...yes? |
| 02:10 | <@Tarinaky> | I felt the rest of the sentence was too obvious to need a completion. |
| 02:12 | <&Derakon> | Well, then you're not really at risk of anything, are you? |
| 02:12 | <&Derakon> | That particular phrase has to be followed by the thing you actually state. |
| 02:13 | <@Tarinaky> | Pick one of "... I don't have that liberty." |
| 02:13 | <@Tarinaky> | Or "I am not a commercial game development studio" |
| 02:14 | <&Derakon> | Hey, I just said it was hard and gave you some context. |
| 02:14 | <&Derakon> | Independent game development isn't easy, especially for 3D games. Why do you think MInecraft is composed solely of cubes? |
| 02:14 | <@Tarinaky> | Sorry, I wasn't trying to be a dick. >.< |
| 02:14 | <&Derakon> | You weren't, just intentionally obtuse. :p |
| 02:15 | <@Tarinaky> | I assure you, I don't have to be intentionally obtuse. |
| 02:15 | <@Tarinaky> | If I were any more obtuse I'd be a straight line. |
| 02:15 | <&ToxicFrog> | Tarinaky: so, for basics, just hack together something that gives you an idea of what it will look like in the GIMP. McMartin's suggestion is a good one. |
| 02:15 | <&ToxicFrog> | For something that looks pretty, you either need an actual artist, or existing artwork for this that has a suitable license. |
| 02:17 | <&McMartin> | There isn't a programmatic solution to the problem of "programmer art" - hence, the entire notion of "programmer art" |

| 05:23 | | Derakon is now known as Derakon[AFK] |
| 05:44 | <~Vornicus> | Okay. The merge iterator takes a vector of frontier maps; it then appears to be a standard input iterator of pairs. |
| 05:46 | <~Vornicus> | The add iterator takes just two frontier maps (of the same type) and appears to be a standard input iterator of pairs. |

| 08:06 | < Xon> | ugh, this project has some /warts/ who the fuck stores integers as doubles in a strongly typed language |
| 08:08 | < [R]> | I see your incorrect type storage and raise you an if/else-chain command processor. |
| 08:09 | < Xon> | That is kinda evil |
| 08:10 | < [R]> | It's part of a function that will sometimes call an overloaded version of itself, that overloaded version then just calls the original again. |
| 08:10 | < [R]> | The only function that ever calls the overload is the original. |
| 08:12 | < Xon> | O_o |
| 08:14 | < Xon> | [R], what is frustrating is that I've repeatedly communicated that this shit needs to store integers =\ |

| 15:34 | <@TheWatcher> | @$_{@keys} = @values for \my %hash; |
| 15:34 | <@TheWatcher> | That is both utterly hideous and extremely neat |
| 15:34 | < jeroud> | So many sigils. |
| 15:35 | <&ToxicFrog> | What does that do? |
| 15:35 | < jeroud> | That can only be the pathologically eclectic rubbish lister. |
| 15:36 | <@TheWatcher> | constructs a hash with the scalars contained in @keys as the keys, and the contents of @values as the values. So if you have my @keys = ("foo", "bar"); my @values = ("A", "B"); then you end up with %keys = ("foo" => "A", "bar" => "B"); |
| 15:37 | <@TheWatcher> | It's another way of doing `my %hash; @hash{@keys} = @values;` |
| 15:38 | <@TheWatcher> | Or plain old `for(my $i = 0; $i < scalar(@keys); ++$i) { $hash{$keys[$i]} = $values[$i]; }` |
| 15:39 | <@TheWatcher> | (and yes, jerith, perl indeed) |
| 15:39 | < RichyB> | In Python, that is phrased as: dict(zip(keys, values)) |
| 15:40 | < RichyB> | Look ma, no sigils! Just a name swiped from ML ("zip") and a convention swiped from Lisp (the association list). |

| 18:06 | < Syka_> | well, you don't if it doesn't work |
| 18:06 | <&Derakon> | (Mostly because it's close to the old printf syntax, which is an ad-hoc standard) |

| 18:10 | <&Derakon> | The other weird thing is that I can print each individual object just fine. |

| 18:10 | <&Derakon> | Tried that. No good. |
| 18:10 | <&Derakon> | I can print each individual member just fine, but printing unicode(self.members) fails. |
| 18:11 | < Syka_> | hmm |

| 18:11 | < Syka_> | "print u"hello %s" % "?"" |
| 18:11 | < Syka_> | this fails |
| 18:11 | < Syka_> | "print "hello %s" % "?"" does not |
| 18:11 | < Syka_> | get rid of the u? |
| 18:12 | <&Derakon> | Uh, both of those work for me. |
| 18:12 | <&Derakon> | And the u is indicating a unicode string. |
| 18:12 | < Syka_> | wait wait |
| 18:12 | < Syka_> | python 2 or 3? |
| 18:12 | <&Derakon> | 2. |
| 18:12 | < Syka_> | hmm |
| 18:12 | <&Derakon> | Necessary third-party libraries aren't available in 3 yet. |
| 18:12 | < Syka_> | because the first one fails with the error you have |
| 18:13 | <&Derakon> | Oh, was that an accented 'o'? |
| 18:13 | <&Derakon> | I can reproduce the error in the REPL by using an accented 'o'. |
| 18:13 | < Syka_> | ...yes that's what I had? |
| 18:13 | <&Derakon> | The accent didn't come through in this IRC client. |
| 18:13 | <&Derakon> | This is bizarre. |
| 18:14 | < Syka_> | also, unrelated |
| 18:14 | < Syka_> | STEAM SUMMER SALES ARE UP |
| 18:14 | <&Derakon> | Why would removing a "treat this string as unicode" indicator fix a failure-to-translate-unicode error? |
| 18:14 | <@gnolam> | Derakon: where are you printing this to? |
| 18:14 | <&Derakon> | Gnolam: terminal. |
| 18:14 | <@gnolam> | Because Python + windows console = fail. |
| 18:14 | <&Derakon> | OSX terminal. |
| 18:15 | <&Derakon> | Again, I can print the individual members just fine, and the accents do show. |
| 18:15 | <@gnolam> | Ah. Don't know about OS X's terminal. |
| 18:15 | <&Derakon> | So it's not a terminal problem. |
| 18:15 | <@gnolam> | Ah. |
| 18:15 | <&Derakon> | It's when I try to print all the members at once that I get the error. |
| 18:16 | <&Derakon> | ...ha. "print self.members" doesn't work. "print unicode(self.members)" doesn't work. |
| 18:17 | <&Derakon> | "print map(unicode, self.members)" does work. |
| 18:17 | <&Derakon> | What the Christ. |
| 18:18 | < Syka_> | oooh. |
| 18:18 | < Syka_> | does self.members get called by repr |
| 18:18 | < Syka_> | does repr handle unicode okay? |
| 18:18 | <&Derakon> | It's in __repr__, yes. |
| 18:19 | <&Derakon> | ...oh, should I be using __unicode__ instead? |
| 18:19 | < Syka_> | i... don't know |
| 18:20 | <&Derakon> | Changing __repr__ to __unicode__ does seem to have fixed the problem in this case. |
| 18:26 | <&Derakon> | Whoof, writing the savefile took almost 10 seconds this time. I think my previous serializations were incomplete. |
| 18:26 | <&Derakon> | (And the savefile itself is 14MB...) |
| 18:27 | <@Tarinaky> | Is this before or after you mangle it through a compressor? |
| 18:27 | <&Derakon> | Compression brings it down to 1MB. |
| 18:27 | <&Derakon> | Oh, this is with profiling turned on, forgot about that. |
| 18:27 | <@Tarinaky> | That's a lot of save file. |
| 18:28 | <@Tarinaky> | RPG or something? |
| 18:28 | <&Derakon> | My time is split pretty evenly between the "analyze data and convert to JSON-acceptable formats" and "actually encode the data with the json library". |
| 18:28 | <&Derakon> | It's the Debug Town for Pyrel, which is a roguelike. |
| 18:28 | <&Derakon> | But it's saving things in a rather abstract way. |
| 18:28 | <@Tarinaky> | Ah-hah. Not just a save file then. |
| 18:29 | <&Derakon> | Since the engine is trying to be agnostic about how things are arranged. |
| 18:29 | <@Tarinaky> | Since it also contains the world and maps and stuff as well. |
| 18:29 | <&Derakon> | Well, Pyrel doesn't have persistent levels, but yeah. |
| 18:31 | <&Derakon> | The main thing is that it's encoding all of the object interrelationships automatically. |
| 18:32 | <&Derakon> | So e.g. this wall is a Terrain datatype that contains a Stats object that contains two StatMod objects. |

| 18:47 | < RichyB> | Pyrel ? |
| 18:49 | < RichyB> | Derakon: I'm not going to do it tonight, but would you like to remind me at some later point to do the work to wrap a proper ordinary C extension about the "heatmap" code so that it just builds with ordinary setup.py instead of you having to work out how to bundle the .dll or .so file? https://github.com/RichardBarrell/heatmap-for-Derakon |
| 18:50 | <&Derakon> | RichyB: that would be awesome, yes. |
| 18:51 | <&Derakon> | There's no rush, though; we have a system that basically works for the developers (who all have the necessary compilation tools). |
| 18:51 | | * RichyB stuffs that into the middle of ~/.plan |
| 18:51 | <&Derakon> | But more simple = more better, as always. :) |
| 18:51 | <&Derakon> | Thanks again for your work on the heatmap. :) |
| 18:51 | < RichyB> | No worries. |
| 18:52 | < RichyB> | PyRel is on Github too, right? |
| 18:52 | <&Derakon> | Bitbucket. |
| 18:52 | <&Derakon> | https://bitbucket.org/derakon/pyrel |
| 18:52 | <&Derakon> | But it uses Git. |
| 18:53 | <&Derakon> | (Much to my dismay, I couldn't convince the other devs to figure Mercurial out...) |
| 18:53 | < RichyB> | Ah cool. I use bitbucket in work. |
| 18:53 | < RichyB> | Yeah, I used to ignore them until they added good Git support. ;) |
| 18:53 | < RichyB> | We use bitbucket in work because their pricing model works for us. |
| 18:53 | | * Derakon nods. |
| 18:53 | < RichyB> | They charge per-user, github charge per-repo. |
| 18:54 | < RichyB> | We have lotsa repos, few users. |
| 18:54 | <&Derakon> | Ahh. |
| 18:54 | <&Derakon> | Here at work we have, uh, 1 repo and 1 user. |
| 18:54 | < RichyB> | Also, github recently changed their UI and I fucking hate the new one. |

| 18:54 | < RichyB> | Some thundering retard appears to have deliberately reduced the prominence of the goddamn clone URL. |
| 18:55 | <&Derakon> | D'oh. |
| 18:55 | < Syka_> | it's right in the corner |
| 18:55 | < Syka_> | you use the clone URL once per project |
| 18:55 | <&Derakon> | And it's the first thing you do in that project, before you know your way around. |
| 18:55 | < RichyB> | I don't know, I assume that it's probably objectively better according to some metric. |
| 18:55 | < Syka_> | right at the top, it took like |
| 18:55 | < Syka_> | 60px |
| 18:56 | < Syka_> | that's terrible |
| 18:56 | < RichyB> | I don't really care, because it's personally worse for me right now. |
| 18:56 | < RichyB> | So yeah, woo bitbucket. |
| 18:56 | <&Derakon> | Heh. |
| 19:21 | <&ToxicFrog> | Yeah, personally I don't mind no longer having the useless clone URL taking up a huge chunk of screen right at the top. |
| 19:21 | <&ToxicFrog> | And I'm feeling pretty charitable towards github right now because they reinstated downloads~ |
| 19:23 | < RichyB> | Jenkins is really nice... |

| 20:15 | | Kindamoody|out is now known as Kindamoody |
| 20:25 | <&Derakon> | Erk, my deserializer has a problem. It can't differentiate between sets and custom classes that inherit from sets. |
| 20:25 | <&Derakon> | And as a result, when deserializing, you always get sets out. |
| 20:25 | <&ToxicFrog> | Oops. |
| 20:26 | <&ToxicFrog> | Oh, that reminds me. Rogue Legacy, as a procedurally generated platformer, may be relevant to your interests if you haven't already played it. |
| 20:26 | <&Derakon> | The problem here is that a custom class that descends from set doesn't pass isinstance(object, types.InstanceType). |
| 20:26 | <&Derakon> | TF: yes, I've been keeping an eye on it. |
| 20:26 | <&Derakon> | I'm hoping that by the time I finish with AP, there'll be a Mac port~ |
| 20:27 | <&ToxicFrog> | FWIW, it works flawlessly in wine under linux |
| 20:27 | <&Derakon> | Since it's liable to be the kind of game that I'd play for 15-30 minutes at a stretch, not really worth rebooting for. |

| 20:40 | <~Vornicus> | What's the question? |
| 20:41 | <&Derakon> | How do I detect that an object is an instance of a class when the class it is an instance of inherits from a builtin like set or dict? |
| 20:41 | <&Derakon> | isinstance(object, types.InstanceType) fails in that case. |
| 20:42 | <~Vornicus> | um. |

| 20:46 | <~Vornicus> | Yes. |

| 20:53 | <&Derakon> | Yes. |
| 20:54 | <&Derakon> | The workaround I'm using for now is "hasattr(object, '__class__') and object.__class__.__name__ in my registry of serializable objects". |
| 20:54 | <&Derakon> | s/objects/object types/ |
| 20:56 | <&Derakon> | ...unfortunately, object.__class__.__name__ appears to be 'type' in one case. WTF? |
| 20:56 | <~Vornicus> | wtf |
| 21:00 | <&Derakon> | Oh, dumbass mistake on my part. |
| 21:00 | <&Derakon> | "lambda **kwargs: Categories" is not the same thing as "lambda **kwargs: Categories()". |

| 22:15 | <&Derakon> | Interesting. A save of the largely-empty Debug Town is 14MB; a save of a dungeon full of walls and corridors and creatures and so on is 16MB. |
| 22:16 | <&ToxicFrog> | I kind of suspected that a lot of the size of the empty town is overhead that you'll have in any save file. |
| 22:16 | <&Derakon> | Yeah, my expectation is that much of this cost is just storing the map grid. |
| 22:18 | <&Derakon> | Y'know, for all the inefficiencies in this system, this is Really Cool. |
| 22:20 | <&Derakon> | All an object needs to do to be [de]serializable is: 1) have a unique ID across all objects; 2) have a function that creates a new blank instance of the object type; 3) (optional) have a function that populates a blank instance with data (otherwise, setattr is used); 4) have a function that returns a dict of the object's data for serialization (ofter, this is simply object.__dict__); 5) register with the serialization module. |
| 22:20 | <&Derakon> | Saving the game involves making a Serializer instance, handing it the GameMap, and telling it to write to a file; it tracks down all the object dependencies itself, converts everything into a JSON-friendly format, and creates the dump. |
| 22:20 | <&Derakon> | Loading the game involves pointing a Deserializer instance at the savefile and calling the load() method. |
| 22:21 | <&Derakon> | Then the getGameMap() function on the result. |
| 22:34 | <&Derakon> | Hmph, somewhere in here a Cell is morphing into a Container, and I have no idea why. |
| 22:35 | <&Derakon> | (Cells are just extended Containers) |
| 22:42 | <&Derakon> | Ah, the problem is likely down to trying to re-use IDs somehow. |

| 22:54 | | mode/#code [+o Reiv] by ChanServ |
| 23:02 | <&Derakon> | Yep, the problem is that when the GameMap is told to add an entity to a Container with a specific ID, it creates a Container with that ID if it doesn't already have one. |
| 23:02 | <&Derakon> | Thus leading to overlapping Containers. |
