And if you are the direct descendent of a sizer then you can specify arguments to the add function with square brackets. |

| 13:18:10 | ftsf | where are the options for --os: defined? |
| 13:18:25 | demi- | euantor: ah, thanks for the explanation! |
| 13:18:40 | ftsf | is that a nim thing? or is it passed to the compiler directly? |
| 13:18:47 | ftsf | (c compiler i mean) |
| 13:19:46 | flyx | ftsf: https://nim-lang.org/docs/nimc.html#cross-compilation |
| 13:19:59 | flyx | it's a Nim thing |
| 13:21:51 | ftsf | mmm, is there a way to specify "no os" ? wanting to try building for something that's going to run on arm bare metal |
| 13:23:05 | flyx | ftsf: what are you expecting to happen by specifying „no os“? |
| 13:23:39 | ftsf | flyx, well i know it doesn't work, but i'm curious what i should specify, and what that option is used for? |
| 13:24:36 | ftsf | i'm using arm-none-eabi-gcc as the c compiler |
| 13:25:01 | flyx | I believe it defines compile-time variables used like `when defined(posix)` and so on |
| 13:25:36 | flyx | there are quite some in the stdlib, so basically it means that you will not be able to use anything in the stdlib which has these sections |
| 13:25:50 | ftsf | I see, so if I disable stdlib it might work |
| 13:26:00 | flyx | you would still need a libc |

| 14:25:18 | Araq | error: size of array 'Nim_and_C_compiler_disagree_on_target_architecture' is negative |
| 14:25:38 | Araq | what do you think this means? |
| 14:27:05 | leru | i understand what it means, but i have no idea, how to fix it. |
| 14:27:14 | FromGitter | <Varriount> leru: As the error says, your Nim compiler is targeting one architecture, while the backend C compiler is targeting another. Which MinGW did you download, and what Nim did you download (x64 or x86/32)? |
| 14:28:08 | * | xet7 joined #nim |
| 14:29:05 | FromGitter | <Varriount> If you downloaded a 64-bit Nim compiler, the MinGW compiler should be of a variant that outputs 64-bit binaries by default. Same for 32 bit. |
| 14:30:41 | FromGitter | <Varriount> Araq: How hard would it be for the Nim compiler to detect the output architecture? I'm assuming it would be fairly easy to implement, and would just involve running some stock commands for each type of compiler to retrieve the default target. |
| 14:31:33 | Araq | varriount, it's an ongoing pita, check tools/finish.nim if you don't believe me |
| 14:31:37 | leru | Alright, I thought there was a secret config or something |
| 14:32:44 | FromGitter | <Varriount> leru: Well, if you have a x64 Nim compiler, I believe you can set the configuration for the Nim compiler to target x86, but that won't work the other way around. |

| 17:01:54 | rokups | thanks Araq, works ;) i had hit a brickwall with gcc/32bit in release builds but figured out workaround. so now coroutines work on all combinations of clang/gcc/debug/release/i386/amd64 (linux) and vcc/debug/release/i386/amd64 (windows). now testing it with optimizations, some of combos still crash. but its getting better. |
| 17:07:45 | rokups | is there any define i could check for optimization level? |

| 17:20:07 | Parashurama | hey! |
| 17:20:53 | Araq | hi |
| 17:20:55 | * | yglukhov joined #nim |
| 17:20:55 | Parashurama | Araq: following github issue. what did I misunderstood? |
| 17:22:36 | Araq | well the default config is C compiler specific, like gcc.options.always = "foo bar" so CC=vcc doesn't break anything |
| 17:23:39 | Parashurama | Okay, and since project/nim.cfg is user responsability, we could do what I suggested. |
| 17:23:50 | * | yglukhov quit (Remote host closed the connection) |
| 17:24:09 | Araq | in Nim code {.passC: "".} is processed after we know the CC so that can in general be protected by a 'when defined(gcc)' (and is) |
| 17:24:32 | Parashurama | for all other people we are talking about: https://github.com/nim-lang/Nim/issues/5307 |
| 17:24:35 | Araq | so --passC is dangerous in a config file and kind of broken on the command line :-) |
| 17:24:49 | Araq | I don't know what follows from all of this. |
| 17:25:22 | Araq | on the other hand, say we have --passC in a config file and no CC |
| 17:25:41 | Araq | we set CC on the command line, then CC resets the passC stuff, exactly what we need |
| 17:26:01 | Araq | so that works too, but it's a bit subtle |
| 17:26:02 | Parashurama | we could maybe deprecate passC/passL on cmdline |
| 17:26:25 | Parashurama | add prefer setting in nim.cfg |
| 17:26:32 | Araq | well we could do your initial proposal so more cases do work. |
| 17:26:37 | Parashurama | or even nim_file.cfg |
| 17:26:51 | Araq | the problem with that is that I cannot see what else might require the same mechanism. |
| 17:27:16 | Araq | what if I set the CPU? doesn't affect passC, i guess |
| 17:27:55 | FromGitter | <andreaferretti> (passC on the command line is also useful for nimble tasks - ideally I would like a single nimble file instead of that + .cfg) |
| 17:28:27 | Parashurama | Yeah not so simple after all! |
| 17:29:14 | Parashurama | andreaferretti: I don't get what you are saying. |
| 17:29:39 | Parashurama | You mean using nimble for everything, even small scripts? |
| 17:30:52 | Parashurama | In theory, my proposal should work (see github issue above), but I might be missing something. |
| 17:31:03 | Araq | isn't this just switch("passC", "value") in NimScript? |
| 17:31:32 | Araq | https://nim-lang.org/docs/nims.html |
| 17:31:43 | Araq | "NimScript as a configuration file" |
| 17:31:58 | Araq | if not, this should be reported as a bug. |
| 17:32:09 | * | brson joined #nim |
| 17:33:51 | Parashurama | I haven't actually used Nimscript before, but it seems interesting. |
| 17:35:37 | Parashurama | If I understand this. in a .nims file I use switch("passc", " -g ") then in the same file: exec "nim c -r test_file" and the option is passed along? |
| 17:36:09 | * | nsf quit (Quit: WeeChat 1.7) |
| 17:36:21 | Araq | lol no. |
| 17:36:39 | Araq | I mean yes, that can work |
| 17:36:57 | Araq | but it doesn't work by passing the config to the subprocess "nim c" |
| 17:37:11 | Araq | instead the subprocess reads the config.nims again ;-) |
| 17:37:47 | Parashurama | Okay. it is a bit convoluted, but it means I can replace my Makefiles with this. |
| 17:38:05 | Araq | yay :-) that was its goal. |
| 17:39:14 | Araq | btw "-g" is "--debugger:native" |
| 17:39:21 | FromGitter | <andreaferretti> My point was that if one removes the possibility to `passC:` on the command line |
| 17:39:45 | FromGitter | <andreaferretti> I would like for that to keep working in nimble |
| 17:40:19 | FromGitter | <andreaferretti> I am not sure if nimble tasks actually shell out a command on the command line |
| 17:40:33 | Parashurama | I think I would like to read the code for nimscript? Where is it hosted? |
| 17:41:12 | FromGitter | <andreaferretti> https://github.com/unicredit/linear-algebra/blob/master/linalg.nimble#L46 |
| 17:42:20 | Parashurama | Well that's much nicer than cmake/makefile syntax :) |
| 17:43:21 | Parashurama | I think I will go play with it. |
| 17:43:50 | FromGitter | <andreaferretti> bye, I got to go |
| 17:44:10 | Araq | hosted? it's part of Nim. |
| 17:44:27 | Araq | Parashurama: I think your proposed fix the best solution for now. |

| 20:13:20 | Araq | make it a 'seq' and it works |
| 20:13:20 | subsetpark | i see! |
| 20:13:45 | subsetpark | thanks Araq |
| 20:13:47 | Araq | maybe the macro can be rewritten to not use closures though, seems slow |
| 20:19:35 | * | unlaudable quit (Ping timeout: 264 seconds) |
| 20:30:59 | Arrrr | Araq, last summer you said you thought about dropping GC support for v2.0. Do you think the same nowdays? |
| 20:31:18 | Araq | hmm? |
| 20:33:28 | Araq | I have some concrete plans now for that |
| 20:33:51 | Araq | but it will still be "automatic" memory management |
| 20:34:10 | Araq | and it's too early to talk about it. |
| 20:35:25 | demi- | would it be an ARC-like system where the compiler inserts the correct retain/release calls at compile time? |
| 20:38:02 | Araq | no, it is better than that. (I hope.) |
| 20:38:21 | Araq | but I don't wanna talk about it. |
| 20:39:59 | demi- | sounds neat |

| 20:44:38 | Parashurama | Araq: PR for passC/passL issue is pushed. |
| 20:47:30 | subsetpark | Is it possible to have a seq of types, which are then instantiated at runtime? |
| 20:48:27 | * | unlaudable joined #nim |
| 20:48:52 | Parashurama | If you mean types which inherit a common parent type, then yes. |
| 20:49:34 | subsetpark | yeah, they do... so is the type of that seq, `seq[typedesc]`? |
| 20:49:42 | Parashurama | otherwise it's a bit more complicated. you can use interface macros and stuff like that. |
| 20:49:58 | * | Parashurama left #nim (#nim) |
| 20:50:07 | * | Parashurama joined #nim |
| 20:50:33 | Araq | subsetpark: don't use seq[typedesc] |
| 20:50:41 | Araq | use seq[RootRef] instead |
| 20:50:49 | Araq | or whatever your base class is |
| 20:50:54 | Parashurama | say you have type Parent = ref object of RootObj |
| 20:51:12 | Parashurama | type Child0 = ref object of Parent |
| 20:51:18 | Parashurama | type Child1 = ref object of Parent |
| 20:51:18 | * | yglukhov quit (Remote host closed the connection) |
| 20:51:30 | Parashurama | and seq type is seq[Parent] |
| 20:51:59 | subsetpark | it's not a seq of values, though. It's more like this: |
| 20:52:10 | subsetpark | type Base = ref object of RootObj |
| 20:52:41 | subsetpark | let myChildren = seq[???] |
| 20:53:12 | subsetpark | for childType in myChildren: let value = childType(...); doSomething(value) |
| 20:53:49 | Araq | you can use RTTI for that I guess |
| 20:54:09 | Parashurama | You mean literally a seq of typedesc. As far I know that's not possible in nim, at least outside macros. This is not python :) |
| 20:54:21 | demi- | can you also use HashSets for this? |
| 20:55:35 | Parashurama | Can you use a PNimType to instanciate a new object ? |
| 20:56:08 | Araq | you can use RTTI which wraps the PNimType stuff somewhat nicely |
| 20:56:29 | Araq | but don't do it. |
| 20:56:56 | Araq | your problem seems backwards. you don't start with a "list of unknown" types |
| 20:57:05 | Araq | that you then need to treat as values, somehow |
| 20:57:17 | subsetpark | Translating from Python, they are a list of subclasses that are parameterized at runtime |
| 20:57:40 | Araq | sounds like you want a macro that takes a varargs |
| 20:58:21 | subsetpark | It might be overkill - the arguments will always be the same, just different values |
| 20:58:50 | subsetpark | They're structured that way for performance reasons, to be able to create classes on the fly rather than store instance variables many times over |
| 20:59:01 | subsetpark | But I suppose maybe they just would all be instance attributes here? |
| 20:59:41 | Araq | no idea. dynamic class creation is usually not done for "performance" |
| 21:00:06 | * | zachcarter quit (Ping timeout: 240 seconds) |
| 21:02:13 | subsetpark | Well - basically I have a 'worker' object, which has a bunch of instance attributes that change over time; i want to create several kinds of workers. The instances will all have their own copies of the instance attributes. There are also a bunch of attributes (always the same attributes) whose values vary per "kind", but not per instance |
| 21:02:17 | subsetpark | How would you structure that? |

| 21:03:17 | * | filcuc joined #nim |
| 21:03:40 | filcuc | how do i change the compiler used from nim from the command line? |
| 21:03:41 | Araq | have a Worker object that contains a RootRef that contains the instance specific data |
| 21:04:05 | Araq | or have all the fields in the worker anyway |
| 21:04:15 | filcuc | second question: can i specify the compiler full path without changing the nim.cfg? |
| 21:04:41 | Araq | --gcc.path="c:\..." might work on the command line |
| 21:05:01 | Araq | subsetpark: or have a 'case kind' in your object |
| 21:05:14 | filcuc | Araq: for the first question? |
| 21:05:26 | Araq | --cc:gcc |
| 21:05:28 | subsetpark | Araq: but "case kind" can't be determined at runtime, right? |
| 21:05:29 | filcuc | Araq: basically i'm integrating the nim compiler in QtCreator toolchains |
| 21:05:53 | filcuc | and already submitted some patches upstream |
| 21:06:11 | Araq | subsetpark: if you don't know your "types" at compiletime, you are not working with "types" at all. |
| 21:06:25 | filcuc | so right now i've to add some option for selecting the compiler that nim should use |
| 21:06:42 | subsetpark | well, that's a matter of debate :) |
| 21:06:43 | filcuc | or at least extract the compiler used by nim and get its abi |
| 21:06:44 | Araq | you then have some fuzzy stuff that might as well be Json |
| 21:07:00 | Araq | filcuc: why? |
| 21:07:11 | * | gokr joined #nim |
| 21:07:28 | filcuc | Araq: not strictly related to nim, but basically QtCreator kits make some checks for ABI between various tools |
| 21:07:49 | filcuc | like between the selected debugger and compiler |
| 21:08:04 | filcuc | they're just some validation checks |
| 21:08:29 | filcuc | but in order to integrate correcly i've to "understand" or "specify" the compiler that nim should use |
| 21:09:19 | filcuc | but it's working more or less, i've also already integrated error messages to QtCreator output messages |
| 21:11:59 | Araq | I am not sure QtCreator knows better than me which compiler to use :-) |
| 21:12:06 | * | rokups quit (Quit: Connection closed for inactivity) |
| 21:12:17 | filcuc | ah..btw if any of you have time or will you can test the plugin already since a couple or releases inside QtCreator |
| 21:12:43 | filcuc | Araq: infact it's my job to teach him :) |
| 21:13:26 | Araq | well I dunno. if QtCreator invokes Nim I guess --cc:gcc and --gcc.path are fine |
| 21:13:36 | filcuc | hope to finish this for 4.3 |
| 21:13:53 | filcuc | Araq: that's all i needed to know |
| 21:13:58 | filcuc | (thanks) |
| 21:14:11 | filcuc | does it work with a possible cross compiler? |
| 21:14:40 | Araq | yeah, e.g. --os:linux --cpu:x86 |
| 21:14:49 | filcuc | suppose i add a compiler in QtCreator...with a name "arm-linux-gnueabi-gcc" |
| 21:15:01 | Parashurama | Araq: hey I trying to fix: https://github.com/nim-lang/Nim/issues/5042 |
| 21:15:02 | filcuc | i mean the cfg for gcc matches also for this compiler? |
| 21:15:32 | Parashurama | Where do you think I should start, with type inferance |
| 21:15:38 | filcuc | o have i to add some lines inside the cfg for supporting this compiler? |
| 21:15:57 | Araq | Parashurama: just let it be. |
| 21:16:10 | Araq | spent weeks on these things. |
| 21:16:31 | filcuc | in other words: can i specify with "--cc:some_compiler" any arbitrary compiler executable (also not specified inside nim.cfg)? |
| 21:16:38 | cheatfate | unsigned integers in Nim is main flaw :) like unsafe pointers in C |
| 21:17:09 | Araq | filcuc: no, Nim needs to understand the backend compiler |
| 21:17:27 | Araq | besides, there are only a handful of C++ compilers left. |
| 21:17:37 | Parashurama | Oh. it's all linked to an unsigned int problem. |
| 21:17:54 | Araq | your "arm-linux-gnueabi-gcc" would be --cc:gcc too |
| 21:18:07 | Parashurama | well, onto the next issue i can try to solve. only 881 left :) |
| 21:18:32 | Araq | Parashurama: most "bugs" are minor annoyances and feature requests |

| 21:38:30 | krux02 | The issue that was fixed was the reverse |
| 21:39:23 | krux02 | it was when I reference an ast from a quote, and then change it, but in issue #881 I insert a node with backticks |
| 21:40:11 | * | filcuc joined #nim |
| 21:40:19 | krux02 | I am not sure if an insertion with backticks is inteded to copy the tree or not, I think no matter what it does, there could be reasons for it, but currently it copies the node |

| 21:41:09 | Araq | krux02: hmm I don't know. would by ref be sound? |
| 21:41:31 | Araq | we don't want to be able to modify the ASTs through 'quote do' |
| 21:43:18 | krux02 | It is useful to use quote do, to reference into the AST though |
| 21:43:42 | krux02 | but on the other end, in most cases the quote do can also just be placed behind all modifications |
| 21:49:49 | Araq | hmm I think I finally understand your problem |
| 21:49:54 | Araq | how come it copies? |
| 21:50:14 | Araq | shouldn't the nodes internally have the nfIsRef flag set already? |

| 21:54:51 | Parashurama | Araq: btw the gc_stack is really a non-issue. you are not supposed to import system/gc_stack into your module, everything is already available from system.nim (included via system/mmdisp.nim) |
| 21:55:18 | Araq | so write that and close the bug |
| 21:55:33 | Araq | or let me close the bug now |
| 21:55:47 | Araq | you need to fix more to get write access to the repo :P |
| 21:56:31 | Parashurama | I will add a comment on this issue and go to the next one in the list. |
| 21:58:18 | Parashurama | You can now close issue: https://github.com/nim-lang/Nim/issues/5308 |

| 22:45:48 | PMunch | Hmm, sometimes Nim reports an error on the wrong line |
| 22:46:37 | Parashurama | That a pretty old error. mostly around template defined in sytem.nim |
| 22:46:41 | cheatfate | PMunch, only seen this with templates which using templates |
| 22:46:51 | Parashurama | in iterator for seq/array etc... |
| 22:47:00 | PMunch | http://ix.io/1RD0 |
| 22:47:08 | PMunch | That's the code I currently have |
| 22:47:16 | PMunch | And it reports an error on line 88 |
| 22:47:28 | PMunch | But the error doesn't actually occur until line 101/102 |
| 22:47:44 | Parashurama | Let's try to make a smaller test case. :) |
| 22:48:03 | PMunch | Yeah, sorry about that :P |
| 22:48:04 | * | bjz quit (Quit: My MacBook Pro has gone to sleep. ZZZzzz…) |
| 22:48:20 | PMunch | Hmm, commenting out the dumptree statements makes the error appear at line 102 |
| 22:48:42 | PMunch | With just the top one it occurs on line 72 |
| 22:48:56 | PMunch | So it always seem to occur on the last line of the previous dumptree.. |

| 22:50:47 | PMunch | There |
| 22:50:51 | PMunch | A more minimal example |
| 22:50:57 | * | filcuc quit (Quit: Konversation terminated!) |
| 22:51:14 | PMunch | First a dumptree, then a macro definition which creates some bad AST, then the call |
| 22:51:48 | PMunch | Defining the macro before the dumptree makes no difference |
| 22:52:46 | * | pregressive quit (Remote host closed the connection) |
| 22:52:55 | Parashurama | just tried it with your reduced testfile. can reproduce. |
| 22:56:50 | Parashurama | interesting bug. this seems related to dumptree, since I couldn't reproduce the bug with another macro invocation in its place |
| 22:57:15 | PMunch | Yes it seems like it |
| 22:57:29 | PMunch | Not quite sure what causes it though.. |
| 22:57:44 | Araq | vm.nim c.comesFromHeuristic ;-) |
| 22:59:30 | Parashurama | PMunch: you probably should write a new issue. |
| 22:59:53 | Parashurama | Araq: that sounds like good start. |
| 23:00:04 | Araq | meh don't report it please |
| 23:00:11 | Araq | pushing a fix alredy |
| 23:00:14 | Araq | *already |
| 23:00:20 | PMunch | Oh nice :) |
| 23:00:26 | Parashurama | damn you are fast. |
| 23:00:48 | Parashurama | but you probably know the compiler like the back of your hand |
| 23:01:08 | * | couven92 joined #nim |
| 23:01:28 | Araq | no, it's just that I recently looked at a similar problem and remembered "that is weird" :P |
| 23:02:02 | Araq | but yeah, I know most parts of the compiler very well |

| 23:03:09 | Parashurama | I'm wrapping the string slice issue before going to sleep (writing test-cases is boring) |
| 23:03:17 | Parashurama | *wrapping-up |
| 23:04:00 | Araq | wrapping up? |
| 23:04:13 | Araq | does that mean you fixed it? |
| 23:04:35 | Araq | https://github.com/nim-lang/Nim/issues/4992 |
| 23:04:44 | Araq | is a nice exercise in compiler development |
| 23:04:59 | Araq | any takers? |
| 23:05:04 | Parashurama | yeah, the code suggested in the issue was already mostly working. I'm just writing a test file. |
| 23:05:42 | Parashurama | maybe tomorrow. it already past midnight where I live. |
| 23:07:18 | Araq | same timezone as me then |
| 23:07:35 | Parashurama | I live in France at the moment. It's pretty nice. |
| 23:13:18 | Parashurama | Araq: okay good night. |

| 23:38:23 | dyce[m] | when declaring variables before the routes in jester, nim says that its not gcsafe, does that mean if you reassign the variable to a new object, the unreferences objects wont get deleted? |
