| 00:02:22 | skrylar_ | Araq this is an API situation though |
| 00:02:41 | skrylar_ | in the case of GL you have to decide when you make the wrapper (though don't we already have one?) |

| 07:08:09 | Vi- | Can I somehow get a __declspec(dllimport) on a variable? After some headaches I managed to get the opengl wrapper to use glew so I can do this now: |
| 07:08:14 | Vi- | var GLEW_KHR_debug {.importc: "__imp____GLEW_KHR_debug"}: GLboolean |
| 07:08:20 | Vi- | but the __imp__ prefix bothers me a bit |
| 07:11:51 | Araq | you can use Nim's dynlib module for this but it has no compiler support |
| 07:13:01 | Vi- | Oh I did try this: var GLEW_KHR_debug {.dynlib: "glew32.dll", importc: "__GLEW_KHR_debug"}: GLboolean |
| 07:13:32 | Vi- | but still getting a linker error |
| 07:13:58 | FromGitter | <ephja> do dll's really support variables? |
| 07:14:03 | Vi- | yes they do |
| 07:15:45 | Vi- | msvc adds the dllimport for functions automatically but not for variables, I guess thats why this is not working here... |
| 07:15:47 | FromGitter | <ephja> why are you using GLEW? for conditional loading? |
| 07:16:04 | Vi- | yea |
| 07:17:13 | Vi- | Suppose I'll just write a macro for these... I was just wondering if I could add the __declspec(dllimport) instead of typing the __imp__ prefix myself |
| 07:19:56 | FromGitter | <ephja> I dunno if you can. isn't this flag exposed through a function? |
| 07:20:28 | Vi- | Not that I know of, thats why I'm asking ^^ |
| 07:26:52 | Araq | you can also play with the .codegenDecl pragma for variables |

| 07:37:06 | FromGitter | <andreaferretti> We are again over 1000 issues! :-D |
| 07:37:24 | FromGitter | <andreaferretti> I tried this filter to figure out which ones are actually language issues |
| 07:37:32 | FromGitter | <ephja> do we need to declare function pointers instead in order to implement conditional extension loading? |
| 07:37:39 | FromGitter | <andreaferretti> `is:issue is:open -label:"Error messages" -label:"Feature" -label:"question" -label:"Tools" -label:"Stdlib" -label:"Documentation" -label:"postponed" ` |
| 07:37:57 | FromGitter | <andreaferretti> currently it returns 594 issues |
| 07:38:20 | FromGitter | <andreaferretti> more than I would think, but many issues still do not have labels, so there may be many false positives |
| 07:39:27 | Arrrr | Add crash and high priority |
| 07:40:27 | FromGitter | <ephja> but aren't these label exlusions? |
| 07:40:59 | FromGitter | <andreaferretti> yep |
| 07:41:13 | FromGitter | <andreaferretti> there are 29 `Crash` and 19 `High priority` |
| 07:41:35 | FromGitter | <ephja> I'm still annoyed by the inability to track relevant threads on the forum |
| 07:41:59 | FromGitter | <andreaferretti> I would like to help by adding some labels, but I do not have rights to do so |
| 07:42:10 | FromGitter | <ephja> we are funding one more dev now though IIRC, so that's nice |
| 07:42:22 | FromGitter | <andreaferretti> is there a way to grant such right on github without giving full access? |
| 07:48:45 | Araq | andreaferretti: I can give you access rights, I trust you enough |
| 07:52:23 | FromGitter | <ephja> Vi-: I'm thinking about ways to implement conditional loading again |
| 07:52:57 | FromGitter | <ephja> Araq: should we migrate to proc pointers in order to support this? |
| 07:54:34 | Araq | ephja: I'm not a fan, can't we do avaliable(openglProc): bool somehow instead? |
| 07:55:06 | Araq | the compiler produces the proc vars for us, that's quite a nice thing |
| 07:56:12 | FromGitter | <andreaferretti> @Araq thank you, I would appreciate it. I will just add labels for now :-) |
| 07:57:37 | FromGitter | <ephja> would it be necessary to modify the compiler? if so, where do I look? |
| 08:00:09 | FromGitter | <ephja> people are busy, and I can never find what I want in the compiler source |
| 08:00:31 | Araq | ephja: it's in compiler/cgen.nim |

| 10:59:35 | PMunch | And I need to set a color |
| 10:59:57 | PMunch | They are defined as 0-65536 guint16 |
| 11:00:28 | PMunch | This guint16 is set as equal to int16 in the bindings for some reason, so I can't set it to 65536 |

| 11:02:58 | Araq | PMunch: fix the bindings please |

| 11:04:12 | euantor | had a minor success story with Nim this week. An old third party service we use at work refuses to work on Windows Server 2012 R2 for whatever reason.

| 11:30:18 | FromGitter | <dandevelop> Taking a look here: https://nim-lang.org/docs/manual.html#implementation-specific-pragmas-codegendecl-pragma can anyone shed more light on how the format strings work in that example -> $# $#$# ? |
| 11:31:59 | FromGitter | <andreaferretti> @Araq I have tagged a few issues. Would it be a problem to add a couple of labels, such as `macros` or `effect system`? |
| 11:32:40 | Araq | no, of course not |
| 11:33:25 | Araq | dandevelop: for vars $1 is the type and $2 is the name, for procs it's return type, name, parameter list |
| 11:33:29 | Araq | in that order. |
| 11:36:15 | FromGitter | <dandevelop> @Araq: so this: ----> a {.codegenDecl: "$# progmem $#".}: int <---- would generate this: int progmem a ? |
| 11:36:31 | Araq | yes |
| 11:37:22 | FromGitter | <dandevelop> Thank you, is this specified anywhere in the docs? (for vars $1 is the type and $2 is the name, for procs it's return type, name, parameter list) |
| 11:38:52 | dave24 | how can I convert a BiggestInt to a uint8? |
| 11:39:46 | Araq | dandevelop, no a PR would be nice |

| 11:41:32 | dave24 | oh, well that was easy |
| 11:41:35 | dave24 | thanks |
| 11:43:49 | dave24 | is there documentation for that? how does it behave in case of overflow? |

| 12:31:46 | koppeh | Mhh.. question about enums. |
| 12:31:56 | koppeh | I have defined an enum like so: |
| 12:32:05 | koppeh | ShaderType* = enum GLenum |
| 12:32:14 | koppeh | FragmentShader = GL_FRAGMENT_SHADER |
| 12:32:39 | koppeh | And so on. I can not convert from ShaderType to GLenum, apparently? |
| 12:32:45 | koppeh | But if I add {.pure.}, it works? |
| 12:33:13 | * | couven92 quit (Quit: Client disconnecting) |
| 12:43:34 | koppeh | Out of curiosity, why can enums be marked as {.pure.} but not procs? |
| 12:45:12 | koppeh | I suppose this is to avoid forcing a specific typing style on a user of a lib for example, but.. |
| 12:45:47 | koppeh | shader.compile() vs shader.compileShader() ... or compile(shader) vs compileShader(shader) |
| 12:47:51 | Arrrr | you can use this: `from module import nil` |
| 12:52:09 | FromGitter | <andreaferretti> @Araq Does the `tools` label apply to `nim doc` and `nim suggest` or should I use different ones? |
| 12:56:07 | PMunch | Hmm, why is gtk_entry_set_alignment not in the wrapping? |
| 13:08:04 | * | vlad1777d joined #nim |
| 13:14:58 | * | salewski joined #nim |
| 13:16:15 | salewski | PMunch, that one is also in the GTK3 wrapper! |
| 13:16:36 | salewski | Are you using GTK2 because of Windows or Mac? |
| 13:17:18 | PMunch | No |
| 13:18:15 | PMunch | I'm using Gtk2 partially because it is what I had installed, partially because it's what I've used before, and I prefer the look of Gtk2. |
| 13:19:25 | salewski | For Linux there may exist GTK3 themes that look like GTK2. |
| 13:20:06 | salewski | I think the Nim GTK2 wrapper has some missing stuff and some bugs. |
| 13:20:43 | salewski | It is very old, and Dom was the only real user and tester with Aporia. |
| 13:21:09 | PMunch | Hmm, guess I should switch to Gtk3 then.. |
| 13:21:16 | PMunch | That's the second UI switch now.. |
| 13:22:03 | PMunch | Wait, which bindings are there for Gtk3? |
| 13:22:06 | salewski | Now, beside the GTK3 wrapper we even have a GObject introspection based high level wrapper. |
| 13:22:49 | salewski | GTK3 low level is at github.com/ngtk3 |
| 13:23:18 | salewski | High level wrapper is at github.com/stefansalewski |
| 13:23:59 | salewski | But the later is nearly untested still. |
| 13:25:00 | PMunch | Hmm |
| 13:26:03 | salewski | The low level one should be fine! It is for GTK 3.20 created with c2nim. |
| 13:26:39 | salewski | It is used with my NEd Nim editor and with the chess game. |

| 13:28:27 | salewski | And due to no one interested in using it at all. |

| 13:32:04 | salewski | cairo, pango, glib2... |
| 13:33:49 | salewski | The Nim GTK3 bindings have many modules, more than 12... |
| 13:34:19 | salewski | And using names like cairo3 or glib3 makes no sense for these... |
| 13:34:29 | FromGitter | <andreaferretti> I see |
| 13:35:38 | salewski | I have never tried to resolve the name conflicts, as there are still no people really inteested in it. |
| 13:36:22 | salewski | And for the high level wrapper it is better, name is nim-gi, so no toplevel name conflict. |

| 20:17:33 | Araq | Gtk >> wxWidgets? |
| 20:17:53 | PMunch | Well wxWidgets uses native controls across all platform |
| 20:18:15 | PMunch | So it uses Gtk on Linux, MSW (or whatever it's called) on Windows, and Cocoa on Mac I believe |
| 20:19:36 | PMunch | But since the toolkits aren't exactly 1:1 on features some things don't work properly, and other things work on some platforms and not all. |

| 20:42:35 | dom96 | I is here |
| 20:43:30 | subsetpark | I am in nimble hell :( |
| 20:44:33 | * | rauss quit (Quit: WeeChat 1.8) |
| 20:44:55 | subsetpark | I have one binary package that relies on two library packages - i cannot for the life of me organize them such that a) nimble dump raises no errors; b) the binary package is able to import all the modules from the two library packages |
| 20:45:54 | * | couven92 joined #nim |
| 20:46:01 | dom96 | subsetpark: D: |
| 20:46:07 | dom96 | What's the layout of your packages? |
| 20:46:24 | dom96 | I assume the errors you're getting aren't errors but namespacing warnings? |
| 20:46:36 | subsetpark | correct |
| 20:48:33 | subsetpark | https://www.irccloud.com/pastebin/arzn9vYs/ |
| 20:49:43 | subsetpark | That produces no warnings - but when the binary package, which includes that as a dependency, tries to import 'syphus' it fails |
| 20:50:47 | dom96 | You can either "import syphus/syphus" |
| 20:50:54 | dom96 | or get rid of that 'syphus' directory |
| 20:51:05 | dom96 | just have syphus.nim at the top-level |
| 20:51:16 | dom96 | other suphus modules would still need to be in a 'syphus' directory though |
| 20:54:25 | PMunch | Ah, finally got my little notes application working as I wanted :) |
| 20:59:39 | subsetpark | dom96: I see - so the purpose of the 'module-name' directory is for all OTHER modules... |
| 21:00:08 | subsetpark | so if I have syphus.nim at top-level, and (eg) syphus_support.nim in the 'syphus' directory - can i still 'import syphus_support' inside of syphus.nim ? |
| 21:00:09 | FromGitter | <dandevelop> Is there any way to make a nim file automatically compile as objective C? |
| 21:00:34 | dom96 | subsetpark: nope, you'd also need to specify the directory. |
| 21:00:46 | dom96 | For modules that are in the same directory you don't need to specify the directory |
| 21:01:45 | subsetpark | hm i see |
| 21:02:14 | FromGitter | <TiberiumN> @dandevelop I think you can't compile only one file as ObjC, and others as another languages |
| 21:02:21 | FromGitter | <dandevelop> I can rephrase that: is there any way to make the nim compiler automatically translate a file to objective-C instead of C? |
| 21:02:33 | FromGitter | <TiberiumN> yes |
| 21:02:42 | FromGitter | <TiberiumN> "nim c file.nim" |
| 21:02:45 | FromGitter | <TiberiumN> c is not a command |
| 21:02:53 | FromGitter | <TiberiumN> c means C language |
| 21:02:57 | FromGitter | <TiberiumN> so just do "nim objc file.nim" |
| 21:03:03 | FromGitter | <dandevelop> What if I have multiple files in the project? |
| 21:03:21 | FromGitter | <dandevelop> And some of those should be translated to C and others to objective-c ? |
| 21:03:27 | FromGitter | <TiberiumN> oh, then I don't know |
| 21:03:34 | FromGitter | <TiberiumN> why do you want that? |
| 21:04:33 | subsetpark | dom96: in general, for larger projects, is that how you'd recommend it? projectname.nim and projectname/ at the top level, and all imports in projectname.nim are namespaced: import projectname.support1, projectname.support2 |
| 21:04:36 | subsetpark | ? |
| 21:04:40 | FromGitter | <dandevelop> I thought of using an existing C library and somehow my head thought that I should specify C as a translation target for the nim compiler. But maybe those C libraries would also work fine if I do nim objc |
| 21:04:53 | FromGitter | <TiberiumN> yes, they probably would |
| 21:04:57 | FromGitter | <TiberiumN> just try it yourself :) |
| 21:05:03 | dom96 | subsetpark: yep. |
| 21:05:29 | subsetpark | ok, very good to know... that's been a real source of confusion for a while D: |
| 21:05:47 | PMunch | http://serv.peterme.net/uploads/note-example2.png |
| 21:05:54 | PMunch | That's what I was trying to do Araq |
| 21:05:56 | dom96 | subsetpark: Hrm, any ideas how we can make that easier to understand? :) |
| 21:06:17 | dom96 | Maybe I should create a simple barebones Nimble package. |
| 21:06:27 | subsetpark | dom96: I think it's just a matter of giving the readme and the warnings emitted by nimble a once-over. |
| 21:06:30 | PMunch | That would be great dom96 |
| 21:06:40 | dom96 | subsetpark: PRs welcome :) |
| 21:06:54 | subsetpark | yes, now i've got two features to add! |
| 21:07:51 | PMunch | All the text is selectable so I can easily copy it. The top left buttons changes sort order, the first combobox selects if it should sort by Time or Source, the second combobox selects a source (to only view one), and the text entry below is a search bar for the current selection. |
| 21:08:24 | PMunch | It also allows images |
| 21:11:24 | PMunch | And Nim is brilliant, all this is under 250 lines of code :) |
| 21:11:38 | PMunch | Even factoring in the horrible mess that is GUI code... |
| 21:13:54 | subsetpark | dom96: I think in general the play will simply to be more prescriptive - there are too many options now |

| 21:16:40 | dom96 | subsetpark: Hrm, you mean we should tell people what they should do instead of saying "You can either do this or this?" |
| 21:16:46 | subsetpark | Exactly |
| 21:16:55 | * | jsgrant- joined #nim |
| 21:17:15 | PMunch | At least for me when I get to package creating I just want to get it done |
| 21:17:28 | PMunch | So having a sample layout to copy, at least for simple packages, would be great |
| 21:18:51 | * | jsgrant- quit (Remote host closed the connection) |
| 21:19:20 | subsetpark | "You should have a single .nim file with the same name as the nimble file at the top level. You should have any other project source files in the source directory, (which also has the same name by default, but can be specified in the case of hybrid packages). Any modules you import in your top-level .nim module will need to be namespaced with the source directory name." |
| 21:19:55 | subsetpark | Clarity is reassuring :) |
| 21:23:02 | FromGitter | <TiberiumN> what, what srcDir is for? |
| 21:23:55 | subsetpark | srcDir is for specifying the name of the directory that contains all secondary source files required by the project .nim file |
| 21:24:11 | subsetpark | if the directory doesn't share the same name as the project file |
| 21:27:58 | subsetpark | Acctually - I'm wrong about that |
| 21:28:13 | subsetpark | It's not even necessary then, because the secondary source dir will be namespaced in the top-level imports |
| 21:28:24 | dom96 | Ideally 'nimble init' should create a directory layout as well |
| 21:28:32 | subsetpark | So it's only necessary when the "top-level" directory is not actually at the top-level |

| 21:51:01 | fox2 | tricky... |
| 21:56:10 | dom96 | subsetpark: You ask Araq nicely to improve the error messages :P |

| 22:06:24 | subsetpark | So now it's just the original mystery... |
| 22:10:49 | subsetpark | Whoa. Weird - if I move the proc up so it doesn't need a forward declaration, the error goes away. dom96 is that supposed to happen? |

| 22:32:10 | PMunch | Ah, added in highlighting of hits now :) |
| 22:58:02 | FromGitter | <philip-wernersbach> Hey everyone, what's the Nim-y way to specify a return type that can be null, when the underlying type doesn't support null? |
| 22:58:38 | FromGitter | <philip-wernersbach> For instance, a string can be null, so that's easy, but an int cannot be null |
| 22:58:54 | FromGitter | <philip-wernersbach> So I need a way to signal "absence of value" |
| 22:59:21 | subsetpark | philip-wernersbach - generally you are advised to use setinel values or options, as is appropriate |
| 22:59:32 | subsetpark | I like options, though they can be a bit heavy for really low-level stuff |
| 22:59:38 | FromGitter | <philip-wernersbach> sentinel values? |
| 23:00:04 | subsetpark | yeah, like - function and caller both agree that -1 actually means "not present" |
| 23:00:30 | subsetpark | then you can declare a const NOT_PRESENT* = -1 and check for that instead |
| 23:01:20 | FromGitter | <philip-wernersbach> Oh I see, that's not possible here. Normally I would do that, but I need the full range of int data types. |
| 23:01:21 | * | irrequietus quit () |
| 23:01:45 | FromGitter | <philip-wernersbach> That would also present an issue for boolean values |
| 23:01:52 | subsetpark | For one-off things you could also use tuples to create tagged values - have an enum {ok, error} - and return a tuple (error, 0) or (ok, <insert value here>) |
| 23:02:28 | subsetpark | but i would recommend you look into options first - they're in the standard lib and work quite well |
| 23:02:48 | FromGitter | <philip-wernersbach> That's a good idea, but I might as well use options like you say. |
| 23:03:04 | subsetpark | yeah, I use them all over the place |
| 23:03:23 | FromGitter | <philip-wernersbach> Are there examples of Nim projects using options? I know how they work, but I don't really know "best practices" so to speak |
| 23:03:24 | subsetpark | They're particularly good if you want to start using them as a poor man's monad |
| 23:04:09 | subsetpark | Here's an example from a program of mine: https://github.com/subsetpark/ad/blob/master/src/parse.nim |
