08:35:15cheatfateAraq, is it easy to add option to compiler to replace stdlib files?
08:35:23cheatfateor it already present?
08:35:40Araqas I said, --lib
08:35:50Araqsets the library path
08:39:30*vendethiel joined #nim
08:39:34cheatfateyeah but i want to replace only one file, like asyncdispatch.nim (which used by asyncnet.nim, asynchttpserver.nim)
08:39:41cheatfatei dont want to replace whole library

09:02:53euantorcheatfateL why not just fork the standard lib, clone it and replace your file in your fork
09:02:59euantorThen point --lib to the cloned fork?

11:18:26ftsfcheers =) `when defined(profiler):` seems to work
11:21:55kier_did anything happen with regard to https://github.com/nim-lang/Nim/pull/4367 ?
11:33:44Araqkier_: I think it's a compiler bug and I don't want more workarounds
11:33:53Araqbut if it's blocking you I can reconsider
11:39:03kier_Araq: ah okay. i'm not blocking on it. I'll separate the compiler bug into a separate issue
11:59:20derlafffhi guys. want to ask it again: echo 'import nre' > test.nim && nim c test.nim: lib/impure/nre.nim(246, 45) Error: undeclared identifier: 'Option'
11:59:27derlafffis it a bug or I do smth wrong?
12:01:49Arrrrdoes import options fix the issue?
12:02:00derlafffnope
12:02:23derlafffArrrr: 'import options, nre' fails too
12:05:16kier_derlafff: have you tried on the latest Nim version (the devel branch)?

12:40:20Araqthere is a branch where cyclic imports are allowed, but it's still a long way from working
12:40:28ftsfsubtyping?
12:43:57Araqtype Foo = ref object of RootObj

14:01:05ephjaIt's archaic indeed. Is it really necessary to reference C files? What a nightmare it must be for everyone who is implementing similar things in other ecosystems
14:07:15ephjais this in case "constants" are changed at some point? which rarely happens in practice, right?

14:14:38ephjathough I can't see what it is that depends on it in this case. can't the sysctl function be used without referencing the header?

14:40:16michael_campbellAnd have seen it mentioned here a few times.
14:40:44ftsfI guess that's the problem with using global variables
14:43:33dom96I think the compiler needs to detect it and at least give a better error message.

16:01:57PMunchI'm having some trouble using the SDL compiled binaries with the SDL bindings
16:02:38PMunchI might be doing it wrong but it's complaining that the file SDL2/SDL_image.h doesn't exist
16:02:56PMunchWhich makes sense since it's a separate source
16:03:13AraqI usually use the wrappers which don't depend on fucking header files
16:03:25PMunchBut I can't figure out how to make them compile together in a way that the binding likes it..
16:03:37PMunchAraq, and which is that then?
16:03:52PMunchThis is the sdl2 binding from Nimble..
16:04:01Araqthe official SDL2 repo doesn't depend on the headers
16:04:18Araqor maybe I am an idiot and didn't notice.
16:04:41PMunchhttps://github.com/nim-lang/sdl2/blob/master/src/sdl2/image.nim

16:36:11*brson joined #nim
16:38:58PMunchOkay, I think I figured out something that works
16:39:53PMunchI looked in the C source generated for my file and noticed that SDL2 wasn't mentioned as an import, but SDL2/SDL_images was
16:41:15PMunchSo I modified the SDL2 wrapper to not output that and made sure that the Java code for the Android project was set to load the images library
16:41:33PMunchNow it compiles and installs fine
16:42:43dom96Araq: Maybe we should set this up for the Nim repo? https://lgtm.co/
16:43:21PMunchNot 100% sure if it works though since the loadTexture function returns null pointers but that is probably because I need to figure out how to do the paths on Android..

18:08:50PMunchI'm guessing it's because the time delta is so small the precision of the float is the issue?
18:09:06PMunchOr is cpuTime not doing what I think it's doing

19:27:01federico3having used gofmt in-line in an editor, the thing also save you some typing
19:27:19ephjait's not like you save that much typing, but it is indeed necessary with cyclical type dependencies
19:32:15ephjabut it might make code a little more readable
19:36:45ephjabut muh screen real estate :p

21:27:30PMunchyglukhov, you there?
21:27:55yglukhovPMunch: hey whats up!
21:28:25PMunchHi! I'm still fiddling with this SDL cross platform stuff
21:28:48PMunchGot everything running smoothly now with SDL2 and SDL image
21:29:18PMunchAnd started writing a small library of game related things
21:29:30yglukhovcool!
21:29:37PMunchBut I've run into an issue with opening files on Android
21:30:33PMunchI've written a small Texture atlas parser (only basic support so far) which works great on desktop
21:31:04PMunchBut when trying to run it on Android I only get a file not found exception when using the built in file operations.
21:31:39yglukhovdo you put your file in the assets?
21:31:42PMunchNot surprisingly as the files lives inside the APK, but I can't find a way to reference them..
21:31:50PMunchYes, the images loads fine
21:32:19yglukhovwell, images should not differ from other files in any way =)
21:32:29PMunchUsing the loadTexture function from SDL image
21:32:44PMunchI'm guessing it does some sort of wrapping..
21:32:50yglukhovyup
21:32:58yglukhovyou have to use rwops api
21:33:28yglukhovtake a look at resource.nim in nimx. pay attention to `when defined(android)` parts.
21:33:50ephjayglukhov: does nimx have support for running code inbetween main loop iterations?
21:33:54PMunchAh, thanks :)
21:35:41yglukhovephja: not really, but a pr to nimx allowing that would probably take no more than 10 mins of your time ;)
21:35:48yglukhovbut why would you need it?
21:37:34ldleworkyglukhov: 404 http://yglukhov.github.io/nimx/livedemo/main.html
21:38:01ldleworkalso, no DSL!?
21:38:15yglukhovldlework: yeah, just noticed as well... it breaks occationally =)
21:38:32yglukhovdsl? for what?
21:40:20ldleworkyglukhov: yes, because DSL's have never before been associated with GUI toolkits
21:40:27ldlework"the obvious thing"
21:40:56yglukhovyou mean the layout dsl?
21:41:15ldleworkis there one? I don't see it mentioned in the readme
21:41:32yglukhovno, there's no such thing yet.
21:41:45yglukhovim currently working on an editor though
21:41:53ephjayglukhov: well it's not the only way to run code periodically. timers might be what I need to use for communicating with threads
21:42:11yglukhovephja: nimx has got timers
21:42:16ldleworkyglukhov: hopefully your editor generates layout DSL :)
21:42:29yglukhovldlework: sorry, thats json =)
21:42:32ephjaI noticed that, and that's why I mentioned timers :p
21:42:39ldleworkyglukhov: ah that's sufficient
21:43:03ldleworkWe need an Urwid for Nim
21:44:27yglukhovyup, that would be really great. but i think, i've seen something of a kind in nim...
21:44:51ephjathere's termbox, but unfortunately only the 'go' library has windows support
21:46:20ephjathe termbox author said something like "I dunno why you would want to write such applications in C anyway". I guess he wasn't thinking about library writers
21:49:24PMunchAw man, this RWOps thing means I'll have to rewrite my line based loop..
21:49:46PMunchOr write the lines iterator for a RWops stream..
21:50:33ldleworkif a termbox/urwid ever shows up for nim I have some tools I will probably port from python
21:51:16yglukhovPMunch: in nimx, there's an rwops stream which wraps sdl rwops to nim stream.
21:51:23yglukhovjust use it already
21:51:25yglukhov=)
21:51:41ephjathere are termbox bindings
21:51:57ldleworkis termbox anywhere as nice as urwid?
21:52:03ephjanope
21:52:04ldleworkjust wondering, never used it
21:52:06ldleworkdoh
21:52:09PMunchBut that still won't work with the lines iterator
21:52:23ephjaI dunno if windows support could be bolted onto the termbox bindings
21:52:29yglukhovif lines works with nim streams, that it will
21:52:58yglukhov* then
21:54:55ephjayglukhov: why did you decide to roll your own widget toolkit?
21:55:40PMunchBut it doesn't
21:55:57PMunchOnly works with files and strings (which are then opened as a file)
21:56:14ephjastreams are nice
21:57:50PMunchFor many things
21:57:51yglukhovPMunch: anyway, it's almost a one-liner: iterator lines(s: Stream): string = var s: string; while s.readLine(s): yield s
21:57:57yglukhovthere you go =)
21:58:19PMunchOh, streams have a readLine. That changes everything :P
21:58:50yglukhovephja: coz its fun? =)

22:00:03yglukhovok gotta go. see you guys.
22:00:13ephjaI just wanted to know if there were any practical reasons, but it's nice to have a high level library in any case

22:00:38ephjanimqml seems to be coming along nicely though

22:12:39ephjaldlework: is tcod also too low level? I guess it doesn't really have widgets
22:17:17ephjaI don't know which approach to take. maybe I should try to port termbox-go
22:18:50dyce_hmm is there anyway to dump a table to json format?
22:19:08dyce_i have a seq of table[string,string]
22:19:17ldleworkephja: yeah tcod is just a render library
22:19:26ldleworkit just gives you a character based canvas
22:19:34ldleworkwith some roguelike features for line of sight and such
22:22:21*Trustable quit (Remote host closed the connection)
22:26:04Araqdyce_: hmmm json.nim should be able to json tables
22:29:16dyce_Araq: so i guess im looking for something like proc escapeJson , but works on any object. or do i need to build a json object from my sequence of tables?
22:29:18*vendethiel joined #nim
22:33:11Araqwhat does escapeJson have to do with anything?
22:36:06dyce_Araq: i am looking for something like python's json.dump https://docs.python.org/2.7/library/json.html (escapeJson seems close, but only works for a string)
22:37:03Araq*% macro?

22:47:37dyce_hmm
22:47:54dyce_well on a sequence of strings, marshal's $$ does what i want

22:52:21dyce_https://glot.io/snippets/eg9z87axm3 but this doesnt work with a table
22:52:42dom96dyce_: just write a quick proc that does it for you :)
22:54:51dyce_dom96: hmm so with jester should i just be using JObject instead of table?
22:55:24dom96sure
22:57:41ephjadyce_: doesn't it? just that it generates a lot of data for tables for example
22:57:46ephjaIIRC
22:58:21dyce_ephja: it does, is there a way to suppress what is empty?
22:58:49ephjaso it gives you the whole structure, even thought it's not necessary in order to recreate it
22:58:59ephjahm don't think so, but I haven't used it much
22:59:07ephjabut I know it has a couple of limitations

23:12:19ephjaI don't know how close you can get to the same level of convenience while keeping only the essential data.
23:19:25dyce_ephja: i guess this will do https://glot.io/snippets/eg9zzbs7hl
23:20:31ephjaI guess, just that there's no need to generate json strings manually
23:22:04dyce_ephja: hmm what about for a json api?
23:22:13dyce_using jester
23:22:28*kulelu88 quit (Quit: Leaving)
23:23:00dyce_or would the better practice be to use jobject and other data structures that represent json
23:32:16ephjadyce_: you could use this if you want http://nim-lang.org/docs/json.html#add,JsonNode,string,JsonNode

23:40:20ephjaI think you just need to check if "toJson(foo.field1), toJson(foo.field2), ..." compiles
23:41:17ephjadoes the marshal mechanism always succeed? if so then it could even be used as a fallback. more data would be generated in some cases, but it would be convenient
23:42:58ephjaAraq: will getType work? can it replace the 'any' interface?
