| 00:05 | < Turaiel> | What would I use in place of constants in C#? |

| 00:16 | <@McMartin> | C# has "const" |
| 00:26 | | You're now known as TheWatcher[T-2] |
| 00:28 | <~Vornicus> | So, you use constants, in place of constants. |
| 00:30 | < Turaiel> | Makes sense :P |
| 00:30 | | You're now known as TheWatcher[zZzZ] |
| 00:40 | < Turaiel> | What would the best way to represent a local resource be? |
| 00:40 | < Turaiel> | I want to store the image "defaultclip.png" in a variable, but I don't know what type I should use |
| 00:41 | <@McMartin> | That problem can get arbitrarily difficult |
| 00:41 | <@McMartin> | Does WPF has an Image class? |
| 00:41 | <@McMartin> | In Java you'd use java.awt.Image |
| 00:41 | < Turaiel> | Yeah, also an ImageSource class |
| 00:41 | <@McMartin> | .NET probably has some equivalent |
| 00:42 | < Turaiel> | But I'm not trying to store the whole image |
| 00:42 | < Turaiel> | Just a reference to it |
| 00:42 | <@McMartin> | As in "when needed, load this file"? |
| 00:42 | <@McMartin> | Or as in "I only want to load it once"? |
| 00:42 | < Turaiel> | The former |
| 00:43 | < Turaiel> | Do I just make it a string called "defaultclip.png"? |
| 00:43 | < Turaiel> | Or is there some format I need to use to represent a local resource? |
| 00:43 | <@McMartin> | I'd just use a string, for this. |
| 00:44 | <@McMartin> | I mean |
| 00:44 | <@McMartin> | This is about half the problem I'm trying to solve in Project Monocle~ |
| 00:44 | <@McMartin> | But I also want to solve the "only load it once" problem and the "... and I want to attach app-specific metadata to it depending on what *kind* of image it is" |
| 00:44 | < Turaiel> | In the XAML it seems to use an ImageSource |
| 00:45 | <@McMartin> | I have no real experience with XAML |
| 00:48 | < Turaiel> | Sigh |
| 00:48 | < Turaiel> | I hate constructors |

| 00:52 | < Turaiel> | McMartin, if you have time, does this look like reasonable code? http://pastebin.com/pa4E3FSy |
| 00:53 | <@McMartin> | You can abbreviate a lot of this |
| 00:53 | <@McMartin> | public string Title { get; set; } is actually equivalent to all your references to _Title. |
| 00:55 | < Turaiel> | Beyond the setters and getters, is there anything else I can change? |
| 00:55 | <@McMartin> | I'm not superfamiliar with the System.Windows.Media namespace, but I don't see anythign wrong |
| 00:58 | < Turaiel> | The constructor feels wrong |
| 00:58 | < Turaiel> | Probably just because of the names I'm using |
| 00:59 | <@McMartin> | You can also just skip the constructor, have an empty one |
| 00:59 | < Turaiel> | Hm? |
| 01:00 | <@McMartin> | And then use the syntax where you go new Media() { Title = "foo"; Color = ...; /* etc */ }; |
| 01:00 | < Turaiel> | Hmm... that seems like it'd be useful |

| 20:41 | | * Derakon ponders game serialization for Pyrel. |
| 20:42 | <&Derakon> | Am I missing anything, or am I basically completely boned if any of my state takes the form of lambda function pointers? |
| 20:43 | <&Derakon> | (I have entities that basically count down until 0 and then call a function; sometimes that function is a lambda) |
| 20:44 | <&ToxicFrog> | Are python functions not serializeable? |
| 20:45 | <&Derakon> | A quick google suggests you can serialize the bytecode and reconstruct it, but the main thing is the lambda's context. |
| 20:45 | <&Derakon> | In extreme cases this could amount to a single lambda reconstructing the entire game state. |
| 20:46 | <&Derakon> | What I wanted to do initially was to write [de]serialization functions for all Things (in-game entities) and Containers (aggregations of Things), encode the relationships between the two in the savefile, and reconstruct everything back up on load. |
| 20:47 | <&Derakon> | But that doesn't handle lambdas. |
| 20:47 | <&Derakon> | (I think I can make it handle ordinary function references though) |
| 20:49 | <&Derakon> | I can just forbid lambdas in anything that needs to be serialized, of course, but they're so handy. ;_; |
| 20:49 | <&Derakon> | 53 lambdas in the codebase currently. |
| 20:49 | <&ToxicFrog> | I thought python had an existing lib for serializing All The Things. |
| 20:49 | <@McMartin> | Ripping explicit function pointers out of my APIs was a major thing I had to do for Monocle. |
| 20:50 | <&Derakon> | TF: mm, I admit I haven't deeply investigated Python's serializers. |
| 20:50 | <&Derakon> | Ideally I would like a savefile that's relatively legible. |
| 20:51 | <&Derakon> | That may be being greedy though. |
| 20:52 | | Kindamoody is now known as Kindamoody[zZz] |
| 20:55 | <&Derakon> | There are also some security issues with blindly using the pickle module for [de]serialization -- create a custom malicious object that, in its serialize function, does something nasty, and stick it into the pickled file; voila, when loaded, the file is nasty. |
| 20:55 | <&Derakon> | So there's good reasons to want to have a more formal save/load procedure. |
| 20:56 | <&Derakon> | Just like I don't store game resource data in Python files. |
