| 03:22:02 | mcc | In testing, it looks like when I tell deepcopy to copy a recursive structure (a which points to b which points to a) it gets confused and mutates the structure considerably. how surprising is this? |
| 03:36:31 | * | yglukhov joined #nim |
| 03:37:20 | Demos | I'm not suprised that it does not work, but it probably should not do that! |
| 03:38:33 | Demos | there are plans for custom copy operators associated with types (like c++ has), but I'm not sure how well they work as of now |
| 03:39:19 | Demos | and for a recursive structure I think it's reasonable to implement your own thing, since the compiler does not really know which references an object holds actually form cycles |
| 03:40:06 | mcc | Hm |
| 03:40:18 | mcc | It seems like the limitations should at least be documented. |
| 03:40:21 | mcc | I am going to file an issue |
| 03:40:39 | * | yglukhov quit (Ping timeout: 246 seconds) |
| 03:41:14 | Demos | yeah if it corrupts the original object it should probably be an issue |
| 03:41:35 | mcc | actually it is weirder than that |
| 03:41:53 | mcc | unless my tests are wrong, it corrupts the original object *once*, and then if i repeat, it eventually crashes |
| 03:42:53 | Demos | I bet it's because it also screws with the refcounts of the object |
| 03:43:24 | mcc | ugh :( |
| 03:43:34 | Demos | see if calling GC_fullcollect() after each copy makes it crash faster |
| 03:44:09 | * | Jesin quit (Quit: Leaving) |
| 03:44:21 | Demos | so my recomendation would be to just write your own copy function. The compiler has no way of generating correct code for copying a cyclic datastructure (I think) |
| 03:46:47 | mcc | actually, my program does not even contain an instance of deepcopy(). right now i am just trying to document a compiler bug :) |
| 03:47:14 | mcc | my program uses shallowcopy, but i intially wrote deepcopy and found if i deepcopied repeatedly it would crash in a strange way |

| 04:00:13 | Demos | WHELP I just spent a good two hours debugging the fact that I forgot to actually call my render function |

| 04:01:18 | freezerburnV | Demos: The most fun kind of debugging ;) |
| 04:01:44 | Demos | I hope this project works out, it's kinda an insane idea |
| 04:01:54 | mcc | personally i think the most fun kind of debugging is when you find out you have not been executing the same executable your compiler has been producing |
| 04:02:01 | mcc | or perhaps that you have been editing one file and building another |
| 04:02:10 | mcc | "fun" |
| 04:04:07 | mcc | what is the project? :O |
| 04:04:43 | Demos | I'm writing a game engine that uses an in memory sqlite database as it's primary scene datastructure |

| 11:38:16 | flyx | would Nim be of much use in that context? it's for JS-based stuff. is Nim's JS backend good enough to build an electron-based app? |
| 11:38:22 | dom96 | http://electron.atom.io/ |
| 11:38:41 | dom96 | hell yes it is |
| 11:38:51 | flyx | well it has been some time since I last tested it |
| 11:39:29 | flyx | I could try to compile NimYAML with it, so that I do not need the server backend on the live testing page anymore |
| 11:40:10 | dom96 | that would be a good test |

| 11:43:28 | PMunch | I can't help to think that Nim would be great for creating GUIs with the DSL stuff.. |
| 11:47:25 | gokr | We are using electron at Evothings. There are some heavy hitting stuff using it now - like VSCode from Microsoft (!) |
| 11:48:11 | gokr | FWIW Spry (1600 lines of Nim) compiles to js just fine, which means my REPL runs on the web :) |

| 14:53:25 | yglukhov | Araq: hi, narrowed the reason of my memory leaks. table.del(key) makes the gc keep the "deleted" value. if i do table[key] = nil; table.del(key), then everything works. |
| 14:54:01 | yglukhov | i tried to understand delImpl, but it looks too mysterious to me :( |
| 14:54:13 | Araq | it just sets a tombstone |
| 14:54:20 | Araq | so yeah, likely a problem |
| 14:54:31 | yglukhov | could you fix it please? |
| 14:55:50 | PMunch | Does anyone here know if persistent structures have been implemented in Nim? |
| 14:56:37 | namnguyen | what do you mean? |
| 14:56:46 | namnguyen | what is a persistent structure? like a building? |
| 14:57:19 | yglukhov | PMunch: never heard of any done in Nim. you could be the first to implement them ;) |
| 14:57:32 | PMunch | Woo |
| 14:57:49 | PMunch | namnguyen, persistent structures are structures that are imutable |
| 14:58:16 | PMunch | So if you do persistentList.add(item) it will return a pointer to a new structure with the item added but the original will not be modified |
| 14:58:32 | PMunch | To me more efficient most persistent data structures are implemented using tries |
| 14:59:03 | namnguyen | gotcha |
| 14:59:04 | PMunch | This way only a certain, fairly low, amount of nodes have to be copied |
| 14:59:21 | namnguyen | if it is append only, sure |
| 14:59:26 | PMunch | They are great for stuff like undos |
| 14:59:45 | namnguyen | undos, hmm, sounds like Command pattern to me. |

| 15:08:22 | dom96 | I would like to improve async's stack traces. |
| 15:10:20 | yglukhov | dom96, Araq: i think they firstly should be fixed as they are now. |

| 15:12:46 | yglukhov | i've noticed it a couple of times but did not bother to look into it |
| 15:13:08 | dom96 | yglukhov: oh yeah, it's been like that for some time. I think I've become desensitised to it. |

| 15:13:41 | dom96 | Sometimes it points to the macro code which is a bit annoying. |

| 15:24:27 | * | chrisheller joined #nim |
| 15:25:03 | Araq | cannot really see how. a tombstone will eventually be overwritten |
| 15:25:17 | Araq | so it wasn't an unbounded memory leak |

| 15:31:28 | renesac_ | a hobin hood hash table implementation don't need tombstones and is very performant |
| 15:31:39 | renesac_ | could be a solution |
| 15:32:31 | cheatfate | renesac_, faster than cookoo? |
| 15:32:51 | renesac_ | possibly |
| 15:33:10 | dom96 | cheatfate: when we have: await fut or fut2, and one of the futures fails with an error. Do you think the `await` should raise it? |
| 15:33:49 | cheatfate | i dont think so |
| 15:34:00 | cheatfate | dom96, i dont think so |
| 15:34:09 | * | vktec joined #nim |
| 15:34:58 | dom96 | cheatfate: okay. I'm changing the semantics back to what they were with regards to 'await fut' |
| 15:35:09 | cheatfate | dom96, wait |
| 15:35:10 | dom96 | and noticed that the same behaviour was present for 'await fut or fut2' |
| 15:35:35 | dom96 | Now I could also make it so that it's up to the implementation of the infix operator (in this case `or`) |
| 15:35:40 | cheatfate | dom96, if we have technique to catch exception, then you dont need to change everything |
| 15:36:09 | cheatfate | but if we haven't then we need to give a way to recover from failure |
| 15:36:55 | dom96 | Right now you can use 'yield' as I mentioned here: https://github.com/nim-lang/Nim/issues/4170 |
| 15:37:32 | dom96 | You agreed that using 'await' on a future only shouldn't raise. |

| 16:14:03 | renesac_ | or just use "SomeInteger" everywhere and deal with the code duplication and the verbosiness of that type name |

| 16:33:01 | cheatfate | dom96, i think we must divide asyncdispatch.nim into pieces, because currently its a 70kb file and i think it will grow further |
| 16:34:18 | cheatfate | and maybe use `include` in asyncdispatch.nim to include pieces like `posix code` and `windows code` |
| 16:48:27 | dom96 | cheatfate: I dunno, I don't think at ~1600 lines it's not so bad. |
| 16:48:42 | dom96 | But perhaps you're right |

| 20:46:47 | Demos | although I only had to do that when I was static linking aganst glfw |
| 20:46:53 | Demos | I'm using msvc by the way |
| 20:47:07 | Demos | things should be pretty much the same in a mingw or cygwin situation |
| 20:48:32 | WickedShell | ah that gets it through compiling. Fails to load the actual glfw3.dll after that but thats fairly easy to drop into the folder |
| 20:48:49 | Demos | yup! |
| 20:49:01 | Demos | cheers! |
| 20:49:16 | WickedShell | out of curiosity I noticed that when I tried to run the command without that flag and it was crashing on trying to find gl.h it would do it once, but it would never try to compile those files again and just error later on in the build process |
| 20:49:32 | WickedShell | the only way to force it to retry was to delete the contents of nimcache, is this expected? |
| 20:49:37 | WickedShell | (just starting to play with nim) |
| 20:56:15 | Araq | Demos: sounds like you should write a blog post |

| 21:03:25 | elrood | not a real compiler..? ;P nim generates hash files for files it considers compiled, right? wouldn't it suffice to shift the generation of these files to after the c compiler has successfully returned? |
| 21:04:34 | elrood | haven't had a look at the internals obviously, just speaking off the top of my head here |

| 21:06:41 | Araq | elrood: yeah that would work except we call the C compiler in parallel for every C file, so it's slightly more work to determine which compiles failed |
| 21:06:54 | Araq | *compile |
| 21:07:14 | reactormonk | Check exit codes? |
| 21:07:59 | WickedShell | is the parrell build why it was doing "ccoommppiillaattiioonn tteerrmmiinnaatteedd.." ? |
| 21:08:29 | Araq | reactormonk: we do check exit codes |
| 21:09:02 | reactormonk | Araq, hm. Can't correlate that back to the files? |
| 21:09:19 | Araq | reactormonk: well we max() all the return values :P |
| 21:09:37 | reactormonk | Araq, ... |
| 21:09:49 | Araq | WickedShell: cannot follow, but in general the compiler is verbose because I like verbose. |
| 21:10:17 | WickedShell | Araq, http://pastebin.com/vVqJgqAW I was really confused to see it double every letter in compilation terminated |
| 21:10:27 | WickedShell | (line 151) |
| 21:10:28 | Araq | I have seen too many programs die silently. |
| 21:10:49 | WickedShell | I'm good with verbose, but doubled letters was surprising :) |
| 21:11:27 | * | Matthias247 joined #nim |
| 21:11:31 | Araq | I've never seen that error message. |
| 21:11:41 | Araq | it's not something my compiler generates. |
| 21:12:22 | WickedShell | might be something mingw related? (not sure, I just grabbed the win-x64 installer off the nim site last night) |
| 21:12:58 | Araq | maybe it's a race condition in the IO subsystem of mingw |
| 21:14:58 | WickedShell | ah your definetly write its multiple streams going to std out, looks differrent now "ocompimlaptiion telarminated.t" |
| 21:16:45 | Araq | that's why usually full line buffering is enabled :P |
| 21:17:01 | Araq | thinking about it ... I think the Nim compiler relies on some undocumented IO behaviour |
| 21:17:24 | Araq | because only 'echo' is guranteed to properly multi-thread and the compiler doesn't use 'echo' ... |
| 21:17:37 | Araq | oh well, we'll soon get IO locks. :-) |
| 21:20:04 | * | benwbooth joined #nim |
| 21:23:27 | WickedShell | nimble is the package manager, what is the common build tool? (make?) or does the nim community treat it like C/C++ where there are tons of different competing build tools? (part of why I ask is I've been doing a lot of clojure recently where you either use lein or boot) |
| 21:24:46 | * | Live_Programming joined #nim |
| 21:26:10 | * | Live_Programming quit (Client Quit) |
| 21:28:14 | Araq | you can either have a nimble 'task' for it or just do 'nim c project.nim' since Nim always builds complete projects. |
| 21:28:26 | Araq | we don't need a build tool. |
| 21:28:59 | Araq | note that once upon a time we had working --symbolfiles resulting in insanely fast incremental builds |
| 21:29:35 | WickedShell | I'm a bit lazy with the keyboard so having to add the needed flags for some dynlibraries everytime is not exciting... I'll look into arbitrary tasks with nimble then |
| 21:29:35 | Araq | after 1.0 is out or maybe before that we'll clean up --symbolfiles |
| 21:30:00 | Araq | well you can simply put these in a nim.cfg file |
