| 02:23:12 | skrylar | need to update my opengl skillset actually :< |
| 02:23:22 | skrylar | only ever did a small amount of gl2. sadly GL2 is still relevant |
| 02:24:00 | FromGitter | <zacharycarter> those are actual mac borders |
| 02:24:09 | skrylar | shiny |
| 02:24:54 | def-pri-pub | ftsf: Please do it quick if you can. I'd like to get the new version of the package out within the next 20 minutes |

| 02:32:06 | ftsf | def-pri-pub, cool, looks good. raises the exception on missing image, works correctly when the image is present. |
| 02:32:10 | ftsf | definitely an improvement. |
| 02:32:33 | skrylar | oh. poop. i finally realized why people don't always do hardware skinning |
| 02:32:44 | skrylar | works great for the gpu. doesn't work at all for the collision detector |
| 02:34:28 | ftsf | do you use skinning in your collision detection? |
| 02:35:09 | skrylar | well i don't do any of that 'cause i don't sell games. |
| 02:35:15 | skrylar | but yes a lot of people do |
| 02:35:58 | ftsf | hmm Shadow of the Colossus I guess |
| 02:36:38 | skrylar | fps games and action rpgs |
| 02:36:55 | ftsf | hmm mostly they use bounding box style hitboxes for collision detection. |
| 02:36:58 | skrylar | they animate hitboxes yeah |
| 02:37:03 | ftsf | and the animation skinning is just for show |
| 02:37:18 | skrylar | well you might have a cube attached to the limbs |
| 02:37:26 | skrylar | you'd still have to cpu skin *those* |
| 02:37:31 | skrylar | unless you have compute shaders |
| 02:37:39 | skrylar | which 8 year old computers don't iirc |
| 02:37:40 | ftsf | yeah you can get the output of the shader |
| 02:37:46 | ftsf | don't need compute shaders |
| 02:38:00 | ftsf | you can fake it with fragment shaders |
| 02:38:17 | ftsf | but on 8 year old computers you'd do software skinning anyway |

| 08:20:32 | skrylar | i know why people do this, but i wish they dropped the type prefixes on procs |

| 08:21:25 | skrylar | proc plist_dict_get_item*(node: plist_t...) |
| 08:21:44 | rokups | oh totally |
| 08:22:00 | skrylar | when i do them i drop the prefix because then nim will happilly do node.dict_get_item |
| 08:22:13 | skrylar | which you can then templatize with an operator, because nim is awesome |
| 08:22:16 | skrylar | *to an |
| 08:22:45 | skrylar | i've heard the case made you should keep bindings as close to C as possible so that the original docs and examples hold |
| 08:23:45 | rokups | also it kind of makes sense when its called like plist_dict_get_item(node, ...). Not so much in case of node.plist_dict_get_item(...). So one or the other suffers |
| 08:24:24 | skrylar | i guess one could always just put templates over them as aliases |
| 08:25:18 | skrylar | ported my cruddy tensors to nim finally. was happy that template was powerful enough to create some of the filler functions i was using m4 in c with |

| 10:26:02 | FromGitter | <ephja> nah that won't work of course |
| 10:40:22 | FromGitter | <ephja> it would be nice to have a shortcut for something as common as this, but there are more important things to worry about |

| 10:41:42 | Arrrr | `proc `()`*[T](t: typedesc[T]): T = T(x: 1)` also works, at least for 0.16 |

| 11:06:18 | Arrrr | Good lord, save me from `recursive module dependency` |
| 11:08:05 | FromGitter | <ephja> "echo ()(T, 1)" for example would not work because of operator precedence |
| 11:09:52 | FromGitter | <mratsim> You can do `proc xyzT: Foo (t: typedesc[T]): Foo` |
| 11:12:20 | FromGitter | <ephja> I would prefer that convention over what we have now |
| 11:13:27 | FromGitter | <mratsim> nothing prevents you from using it ;) |
| 11:14:16 | FromGitter | <ephja> I'll adhere to the official conventions for now |
| 11:14:50 | * | aziz joined #nim |
| 11:16:19 | FromGitter | <ephja> Anyway, that macro could also act as metadata for documentation generators and other things |
| 11:16:29 | FromGitter | <mratsim> Where did you find them? By the way, you are forced to use my alternative if Foo is an abstract type. You can’t do proc xyz(t: typedesc[int or float]): auto = |
| 11:28:43 | FromGitter | <ephja> well I've come close. I'm not sure if the limitations I've run into are bugs though |
| 11:38:31 | FromGitter | <ephja> @mratsim what limitations did you have in mind? how about this pattern: ⏎ ⏎ ```proc init[U](t: typedesc[T[U]], x: U): t = t(x: x)``` ⏎ ⏎ ? [https://gitter.im/nim-lang/Nim?at=592d59b738b37b98283b64e8] |
| 11:39:48 | FromGitter | <mratsim> I didn’t have any limitations though, you need to declare T as a Generic here by the way. |
| 11:40:18 | FromGitter | <ephja> T[U] = object |
| 11:40:19 | FromGitter | <mratsim> It seems like a pattern `classy`could cover |
| 11:41:23 | FromGitter | <mratsim> ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=592d5a635e34568d5ea55bae] |
| 11:41:51 | FromGitter | <ephja> but it gets more complicated if you want to use a macro like the one posted earlier: https://gist.github.com/rokups/19f82c6ed8c55780e1c39837bd416182 |

| 16:11:28 | FromGitter | <zacharycarter> I don't think they need to be merged - it's advisable IMO to use the official bindings unless you have a strong reason not to |
| 16:11:52 | FromGitter | <zacharycarter> and if something is missing from them PR it |
| 16:12:40 | shmup | ftsf: yeah, about that, did you make pull requests to nim-lang for your sdl2 changes? |
| 16:12:57 | shmup | https://github.com/nim-lang/sdl2/pull/92 |
| 16:12:58 | shmup | ok yes you did |
| 16:13:45 | shmup | I really like Vladar4's work in this area though. he is very efficient: https://github.com/Vladar4/sdl2_nim/tree/master/examples |
| 16:14:02 | shmup | not to mention he included a buncha extra sdl stuff |
| 16:14:27 | FromGitter | <zacharycarter> would be nice if he PR'd it to the official bindings but I also understand his reulctance to |
| 16:14:30 | FromGitter | <zacharycarter> reluctance* |
| 16:15:07 | shmup | regarding ftsf's PR? isn't it? |
| 16:15:24 | shmup | or Vladar |
| 16:15:25 | FromGitter | <zacharycarter> oh I just meant the extra stuff Vladar has exposed / documented / added examples for |
| 16:15:42 | shmup | ah, yeah |
| 16:15:47 | FromGitter | <zacharycarter> I use SDL2 but very little of it |
| 16:15:55 | FromGitter | <zacharycarter> only for windowing / input |
| 16:16:08 | FromGitter | <zacharycarter> I know a lot of folks use it a lot more heavily than that |
| 16:16:58 | FromGitter | <zacharycarter> so it makes sense why his bindings are more attractive to the community, but we should probably work to improve the official ones is all I think |
| 16:17:06 | benny_ | if slicing arrays in nim is expensive, how Do I avoid this? |
| 16:19:07 | def- | benny_: pass the entire thing by reference and use indices? |
| 16:19:31 | benny_ | When I slice, I create a different array? |
| 16:19:52 | benny_ | How do I pass by reference on nim? |

| 16:25:25 | benny_ | Just want to improve my merge sort, I had no time to work on it |
| 16:25:35 | benny_ | can someone modify my gist and fix my newbies errors? |
| 16:25:44 | def- | benny_: sure, give me the gist again |
| 16:25:44 | FromGitter | <Varriount> benny_: For the merge sort, I had a crack at it. |
| 16:25:45 | benny_ | no "errors" |
| 16:26:01 | benny_ | https://gist.github.com/Bennyelg/da85a34c535f16d94633f494ed4720c4 |
| 16:26:30 | FromGitter | <Varriount> benny_: In general, do modifications in-place, pass the entire array in rather than a slice, and use a slice object (created by the `..` operator) as a secondary argument |
| 16:26:34 | benny_ | this merge_sort is working but I want to improve performance with all the swiss knifes nim has. |

| 19:56:52 | skrylar | someone is doing things with matrix? |
| 19:56:59 | skrylar | i thought that system was a neat idea that was doomed to failure |
| 19:57:43 | ehmry | skrylar: why do you say that? I can see the history ballooning out of control |
| 19:59:02 | skrylar | ehmry, because it was neat and simple when i checked it out and people are allergic to neat and simple lol |
| 19:59:14 | skrylar | they have to have overcomplicated and annoying before they will adopt it XD |
| 19:59:28 | ehmry | its true |
| 19:59:50 | FromGitter | <ephja> copyMem might be better in this case. it's not ideal but safer alternatives should be possible with concepts |
| 20:01:24 | skrylar | would anyone happen to know if nim macros can replace say, type declarations without looking too weird? |
| 20:01:53 | skrylar | might not have to though. was just pondering a way to introspect structs for something like blender's dna file format or that one abandoned apache thing |

| 20:04:11 | FromGitter | <ephja> you don't need to bundle the introspection with the type creation |
| 20:05:50 | FromGitter | <ephja> skrylar: https://nim-lang.org/docs/typeinfo.html, https://nim-lang.org/docs/macros.html#getType,NimNode |
| 20:08:23 | FromGitter | <dandevelop> Is there any way to have properties with getters and setters and Nim? Maybe something with meta programming? Ideally it would be something like: button.Text = "Ok" and this would call a function to do the actual work |
| 20:09:11 | skrylar | dandevelop, nim will just use functions for it |
| 20:09:22 | skrylar | proc foo(): bar # i am a getter by default |
| 20:10:04 | skrylar | proc `foo=`(value: bar) # i am a setter |
| 20:10:05 | FromGitter | <ephja> don't you need a parameter for it to be considered a getter? |
| 20:10:13 | skrylar | yes but, well. brevity |
| 20:10:20 | FromGitter | <ephja> right |
| 20:10:23 | skrylar | though technically no, nim will let you call that on its own |
| 20:10:36 | skrylar | change_the_sheets # technically valid? |
| 20:10:59 | FromGitter | <dandevelop> Not sure I understand it. Sorry about this, I am new to Nim. How would this work to pass the "Ok" parameter to some SetText function when I do button.Text = "Ok" ? |
| 20:11:10 | FromGitter | <ephja> it doesn't evaluate to a proc? |
| 20:11:31 | skrylar | proc `text=`(self: var button, value: string) |
| 20:12:06 | * | rokups quit (Quit: Connection closed for inactivity) |
| 20:12:06 | skrylar | nim does a lot of syntactic sugar, so when you say foo.bar = baz nim will actually treat it as `bar=`(foo, baz) |
| 20:16:12 | FromGitter | <dandevelop> Would it be something like this? |

| 20:19:08 | FromGitter | <dandevelop> This actually doesn't compile, it is just out of the top of my head |
| 20:22:52 | FromGitter | <dandevelop> skrylar: is there a self keywod in nim? |
| 20:23:25 | * | benny_ joined #nim |
| 20:23:27 | skrylar | "yes" |
| 20:23:45 | skrylar | the long answer is that its whatever the first parameter of your function is. |
| 20:23:59 | skrylar | you usually name that self (or 'this', i suppose, nim doesn't care.) |
| 20:24:17 | skrylar | there is a {.this:self.} pragma that sets an implicit self |
| 20:24:29 | FromGitter | <dandevelop> type ⏎ ⏎ ```self.theText = value``` ⏎ ⏎ var button:TButton ... [https://gitter.im/nim-lang/Nim?at=592dd4fc631b8e4e612ad0dd] |
| 20:24:37 | FromGitter | <dandevelop> This is what I tried |
| 20:25:12 | skrylar | i was told we stopped calling things TType |
| 20:25:26 | skrylar | i think you forgot the backquotes around `text=` |
| 20:26:03 | FromGitter | <dandevelop> How would that look like? |
| 20:26:32 | FromGitter | <dandevelop> Again, sorry for asking these dumb questions. I am new to nim. |
| 20:28:48 | skrylar | i suspect the chatbot is eating the ticks |
| 20:29:51 | skrylar | there is a backtick before the t and a backtick after the = |
| 20:29:52 | FromGitter | <dandevelop> Maybe something like https://pastebin.com/ would work for this? |
| 20:30:41 | demi- | it might be the chatbot or gitter (since it tries to present rendered markdown) |
