| 00:19:57 | FromGitter | <kayabaNerve> I need some help. I'm trying to compile Nim code, when compilation takes 1.178 GiB of peak memory, on a server with 2 GiB free. That said, GCC still complains about a lack of memory. I tried `--parallelBuild:1`. i do understand the best option is to create a swap file, yet I can't, so I'm looking for a Nim solution. |
| 00:23:20 | shashlick | There was some flag to reduce mem usage but can't find it |
| 00:23:24 | axion | I would recommend cross compiling with such severe memory constraints |
| 00:23:59 | axion | Especially on a sever. The OOM killer could wipe out anything :/ |
| 00:25:31 | FromGitter | <kayabaNerve> axion: I have 2 GB free. |
| 00:25:59 | axion | I saw |
| 00:26:29 | FromGitter | <kayabaNerve> That's not memory constrained |

| 01:58:12 | * | my_dude quit (Client Quit) |
| 01:58:26 | disruptek | use a range or a set. |
| 01:58:33 | FromDiscord | <Varriount> I don't follow - do you mean create a set? |
| 01:59:00 | FromDiscord | <Varriount> disruptek: Long night? |
| 01:59:10 | disruptek | yep. |
| 01:59:15 | FromDiscord | <KingDarBoja> For example, take elements from starting Enum key to ending Enum key, in this case, BANG to BRACE_R |
| 01:59:35 | disruptek | {BANG .. BRACE_R} |
| 01:59:44 | disruptek | or, as a type... range[BANG .. BRACE_R] |
| 02:00:07 | FromDiscord | <KingDarBoja> Oh, was missing the brackets... 🤦 |
| 02:01:20 | disruptek | that emoji renders female in my terminal emulator and male in my notifications. i don't have the energy to ponder how fucked up that is. |
| 02:03:39 | qbradley | (staticExec "gzip -9 -c test.dat").len is returning 112 in my test program, but "gzip -9 -c test.dat | wc" on the command line returns 113 (which is correct). Anyone know how to get my missing byte back using staticExec? |
| 02:04:10 | disruptek | gzip on the cli adds a newline most likely. |
| 02:04:24 | disruptek | because pipe. |
| 02:04:53 | disruptek | write the data to a file and compare with a quality editor. |
| 02:06:23 | qbradley | If I run "gzip -9 test.dat" the file test.dat.gz is also 113 bytes. The final missing byte is not a newline. |
| 02:07:06 | qbradley | I suppose either the staticExec command is producing different output or it is losing a byte of output. I'll write out the resulting data from staticExec and diff |
| 02:07:15 | disruptek | yes. |

| 02:08:27 | FromDiscord | <Varriount> disruptek: Or just diff the input? Pipe the input from gzip to a file, then compare |
| 02:09:09 | disruptek | diff is not so useful for binary comparison, especially when what you're interested in is binary values. |
| 02:09:30 | FromDiscord | <Varriount> Ah, I assumed that the input to gzip was human readable |
| 02:09:43 | disruptek | it's the output that we are interested in. |
| 02:09:54 | qbradley | I hexdumped the files and diffed them |
| 02:09:59 | FromDiscord | <Varriount> Yeah, but for the output to differ, the input must differ |
| 02:10:08 | disruptek | seemingly not. |
| 02:10:32 | qbradley | The files have differences near the beginning and the last bytes. It seems that gzip is working differently when run from staticExec than when run from command line |
| 02:10:49 | FromDiscord | <Varriount> qbradley: Environment variables maybe? |
| 02:10:56 | disruptek | check that it's the same gzip. |
| 02:11:03 | qbradley | the command line is consistent regardless if I pipe the output to wc, or tee, or redirect to a file, or not use -c and let it write to the file directly. All consistent. but staticExec different :-( |
| 02:11:40 | qbradley | Ok, I'll see if "which gzip" works from staticExec |
| 02:12:18 | qbradley | yes, "which gzip" returns /bin/gzip from command line and also from staticExec |
| 02:12:21 | disruptek | it's a bad idea to guess in any event. see `findExe()` |
| 02:12:42 | disruptek | can you repro minimally? |
| 02:13:05 | qbradley | I'll give it a try |
| 02:13:31 | disruptek | i'm thinking it's encoding the filename maybe. |

| 02:14:44 | qbradley | I notice that the last few bytes of the 112 byte file are 0xA. (They are 0x0 in the correctly sized file). Is it possible that staticExec is aggressively stripping a trailing 0xA thinking it is an extra LF? |
| 02:14:54 | qbradley | Obviously in my case the output is binary |
| 02:15:01 | disruptek | yes. |
| 02:15:30 | FromDiscord | <Varriount> Wait, staticExec strips data from the executed output? |

My problem is I have a JsonNode object and I am trying to unmarshal it into a type using the 'to' macro, however the JSON data I have contains a key called type, which means Nim won't let me have a identifier called type in my data structure as it is a reserved keyword.

| 06:17:59 | FromDiscord | <Varriount> Huh. |
| 06:19:48 | leorize | this might mean that `cast` is not implemented correctly... |

| 06:28:29 | FromDiscord | <Varriount> leorize: So, Nim was changed to compare floats according to their bit pattern... but this is incorrect for 0 and -0, because they have a different bit pattern |
| 06:29:12 | FromDiscord | <Varriount> Honestly, I don't think it's worth trying to fight the C backend on this. I'd rather stick with common, expected semantics. |

| 06:30:03 | kungtotte | disrupteq: re: my URL issues with nimph yesterday, I got it working with this change: https://github.com/kungtotte/nimph/commit/9949de85945c0d5a54ae0e4552981dc32c838d35 but it breaks some existing test assumptions in tests/tspec.nim. From looking at it, I think you can drop a lot of those hardcoded assumptions completely out |
| 06:30:46 | FromDiscord | <Varriount> leorize: Again, I don't think Nim should break this particular standard - I'd need to check, but Javascript and (presumably) C both have the `NaN != NaN` behavior |
| 06:31:03 | leorize | well, yea, it's a part of IEEE |
| 06:31:41 | leorize | since this affects generics, I think Araq was just trying to make Foo[NaN] == Foo[NaN] |
| 06:32:25 | leorize | but trust me, if you really want to compare NaN, bringing out a float classifier is always the wise choice |
| 06:32:56 | Araq | well I was aware of 0.0 vs -0.0 and I didn't care |
| 06:33:13 | Araq | in fact, my solution is correct |
| 06:33:26 | Araq | proc foo(x = 0.0) # forward decl |
| 06:33:31 | Araq | cannot be resolved via |
| 06:33:45 | Araq | proc foo(x = -0.0) = implementation here |
| 06:33:58 | FromDiscord | <Varriount> Araq: So we break with the IEEE standard where `NaN != NaN` and `-0.0 == +0.0`? |
| 06:34:08 | leorize | !eval -0.0 == 0.0 |
| 06:34:11 | NimBot | Compile failed: /usercode/in.nim(1, 6) Error: expression 'true' is of type 'bool' and has to be discarded |
| 06:34:23 | Yardanico | !eval assert 0.0 == -0.0 |
| 06:34:26 | NimBot | <no output> |
| 06:34:36 | leorize | IEEE strikes again |
| 06:35:00 | Araq | we don't break the standard omg |
| 06:35:15 | FromDiscord | <Varriount> Oh, I was misreading the code. |
| 06:35:22 | FromDiscord | <Varriount> I thought this was the code generator |
| 06:36:29 | FromDiscord | <Varriount> I'm sorry |
| 06:37:04 | leorize | I never understand why signed zero was a thing |

| 06:37:57 | leorize | I guess it was so that gradual underflow is cheaper to implement |
| 06:38:14 | Araq | signed zero is fine 1.0 / -0.0 = -Inf, 1.0 / 0.0 = +Inf |
| 06:39:03 | Araq | even NaN is ok. the fact that Nan *always* compares false, even with itself, is unprecedented in human history and breaks basic logic |
| 06:39:26 | Araq | it's the worst design in computing that I've ever seen |

| 06:42:15 | Araq | iirc there is a way to do calculus with explicit "finitely small" values that are different from 0 |

| 06:42:59 | silvernode | so I think I hit a nim bug, none of my files have problems in the error, it just says Error: internal error: genTypeInfo(tyNone) |

| 12:59:44 | Yardanico | echo myobj |
| 13:00:18 | Yardanico | if it's a ref object, you can dereference it like echo myobj[] |
| 13:01:02 | lqdev[m] | also, `echo myObj.repr` |
| 13:01:10 | lqdev[m] | works for pretty much everything afaik |
| 13:01:20 | Yardanico | yeah but output is too verbose sometimes |
| 13:01:29 | lqdev[m] | true |
| 13:02:01 | FromGitter | <gogolxdong> Error: type mismatch: got <Client> ⏎ but expected one of: ⏎ proc echo(x: varargs[typed, `$`]) ⏎ first type mismatch at position: 1 ⏎ required type for x: varargs[typed] ... [https://gitter.im/nim-lang/Nim?at=5e7f4ac94a4f8e0a100ef149] |
| 13:02:10 | Yardanico | if it's a ref object, dereference it as I said |
| 13:02:28 | FromGitter | <gogolxdong> yes , I remembered was using repr, but repr doesn't work for me now? |
| 13:02:54 | FromDiscord | <Rika> basically `Client` has no `$` proc it seems |
| 13:03:01 | FromDiscord | <Rika> make one |
| 13:03:03 | Yardanico | well it doesn't have to have it |
| 13:03:11 | FromDiscord | <Rika> really? |
| 13:03:13 | Yardanico | yes? |
| 13:03:28 | FromDiscord | <Rika> hmm interesting, never noticed it |

| 13:04:35 | Yardanico | !eval type A = ref object; echo A()[] |
| 13:04:37 | NimBot | () |
| 13:05:10 | FromDiscord | <Rika> so what is Client? the error differs to what happens if you dont deref a ref |
| 13:06:22 | FromGitter | <gogolxdong> type ⏎ Client = ref object |
| 13:06:40 | Yardanico | @gogolxdong as I said, dereference it like echo myclient[] |
| 13:06:42 | FromGitter | <gogolxdong> echo client[] |
| 13:07:00 | FromDiscord | <Rika> does that work? |
| 13:08:13 | FromGitter | <gogolxdong> no |

| 20:32:59 | FromDiscord | <KingDarBoja> https://play.nim-lang.org/#ix=2fOo Anyone knows where the "16" comes from on the second find at this example? |
| 20:33:41 | * | my_dude quit (Quit: ZZZzzz…) |
| 20:35:48 | leorize | in the string representation of PunctuationTokenKind |
| 20:35:52 | leorize | what are you trying to do? |
| 20:36:05 | FromDiscord | <Rika> sets dont have an order perse |
| 20:36:32 | FromDiscord | <Rika> 16 is the index of the character of the string representation of the set |
| 20:36:40 | FromDiscord | <Rika> from* |
| 20:36:52 | FromDiscord | <Rika> 16 is the index of the character [from] the string representation of the set |
| 20:38:21 | FromDiscord | <KingDarBoja> Leorize: check if a value is at the set[TokenKind], which is called PunctuatorTokenKind as the find search will return -1 if not found. |
| 20:38:35 | leorize | lol find() only works for arrays :P |
| 20:38:39 | FromDiscord | <KingDarBoja> Then if it is not -1, find the associated Enum value at TokenKind |
| 20:38:50 | FromDiscord | <Rika> find works with something with an order |
| 20:38:57 | leorize | convert it to TokenKind, then you can check if it's in PunctuactionTokenKind |
| 20:39:04 | FromDiscord | <Rika> an enum is individual "variables" |
| 20:39:06 | * | FromDiscord <KingDarBoja> insert big stonk face |
| 20:39:36 | FromDiscord | <Rika> and the first one isnt even 0 |
| 20:39:37 | FromDiscord | <Rika> its |
| 20:39:40 | FromDiscord | <Rika> 1*, its 1 |
| 20:40:07 | * | jjido quit (Quit: My MacBook has gone to sleep. ZZZzzz…) |
| 20:40:11 | FromDiscord | <KingDarBoja> Yeah, forgot to mention that, I realized my mistake after getting the 16 |
| 20:40:14 | FromDiscord | <Rika> sets dont have "order" |
| 20:41:12 | FromDiscord | <KingDarBoja> The conversion to TokenKind is done with parseEnum, right Leorize? |
| 20:41:13 | leorize | if you wanna write a lexer, I'd recommend using `lexbase` |
| 20:41:16 | leorize | yep |
| 20:42:02 | leorize | lexbase provides a solid base to write any lexer, as it got an excellent buffering system |
| 20:42:16 | * | jjido joined #nim |
| 20:43:54 | FromDiscord | <KingDarBoja> I saw the suggestions, but more like writing the same code logic from source code so every change on the base implementation can be reflected on my code.... I know that sounds like non-sense |
| 20:44:10 | FromDiscord | <KingDarBoja> Not the best explaining stuff to be honest 😢 |
| 20:44:20 | leorize | you can read the stdlib's json and cfg parser to see how a lexer is written :) |
| 20:44:41 | leorize | https://github.com/alaviss/toml/blob/master/toml.nim <- this is my own lexer, it's old though, I've abandoned it |
| 20:45:16 | leorize | actually I think I wrote a lexer somewhere in rosetta code that's a touch more up-to-date |
| 20:45:25 | FromDiscord | <KingDarBoja> I am interested on the statement "the string representation of the set" wtf is that? o.o |
| 20:45:57 | leorize | the `$` operator returns the string representation of whatever you put into it |
| 20:46:04 | leorize | try to echo the const you made |
| 20:46:12 | FromDiscord | <KingDarBoja> Sure, let me try |
| 20:46:45 | FromDiscord | <KingDarBoja> I see this -> {!, $, &, (, ), ..., :, =, @, [, ], {, |, }} |
| 20:47:26 | FromDiscord | <KingDarBoja> Oh! got it! |
| 20:47:33 | FromDiscord | <KingDarBoja> Yeah, now makes sense to me |
| 20:47:36 | FromDiscord | <Recruit_main707> how do i initialise something like this: type Vector3* = ptr object?? |
| 20:47:56 | FromDiscord | <Recruit_main707> having as fields x, y, and z? |
| 20:48:15 | leorize | result = Vector3(x: 0, y: 0, z: 0) <- use the type contructor |
| 20:49:12 | FromDiscord | <Recruit_main707> `object constructor needs an object type` |
| 20:50:05 | leorize | well, try `create(Vector3)` then |
| 20:51:03 | leorize | why do you want to create an object though? |
| 20:51:10 | leorize | ptr object* |
| 20:51:28 | leorize | usually people don't use it unless they're interfacing with C |
| 20:51:46 | FromDiscord | <Recruit_main707> to my knowledge, `ref` is very slow, |
| 20:52:19 | leorize | it's as slow as `ptr` fwiw :) |
| 20:53:12 | FromDiscord | <Recruit_main707> shouldnt it be faster than `object` then? |
| 20:53:20 | FromDiscord | <Recruit_main707> at least interfacing w/ C? |
| 20:53:21 | leorize | no |
| 20:53:27 | leorize | nothing beats the stack |
| 20:53:37 | leorize | you use the heap when you need it, not because you can |
| 20:53:55 | FromDiscord | <Recruit_main707> ok, thanks |

| 20:55:57 | dom96 | ugh, pretty sure nim devel has a leak in HashSet's |
| 20:58:12 | leorize | how? :P |
| 20:58:56 | dom96 | I decided to spend my day optimising my game |
| 20:59:03 | dom96 | I reduced the code to a HashSet iteration |
| 20:59:19 | dom96 | and saw it increase in time spent over time |
| 20:59:32 | dom96 | switched to 1.0.6 and that doesn't happen |
| 20:59:38 | dom96 | so yay, nice waste of my time |
| 21:00:29 | leorize | now it'd be nice if you can fix it :) |
| 21:00:40 | FromDiscord | <Rika> time spent over time? |
| 21:00:58 | dom96 | increase in time spent over the run time of my game |

| 21:01:20 | FromDiscord | <Rika> still dont get it, dont bother explaining because itll take too much time |
| 21:01:44 | dom96 | I'm just annoyed now. I'll try to repro but if I can't do it in 20 minutes I will instead rant on the PR that likely introduced this |

| 21:38:42 | dom96 | disbot works via discord? |

| 22:40:28 | blackbeard420 | when using std json's `to` is there a way to make it ignore certain fields? |

| 22:41:28 | FromDiscord | <Rika> why wouldnt it? |
| 22:41:36 | FromDiscord | <Rika> blackbeard420, not that i know of |
| 22:42:18 | disruptek | search for noserialize; there are a few discussions/solutions. |
| 22:42:19 | FromDiscord | <Rika> you can always remove it from the json node the `to` macro's gonna process |

| 22:55:25 | FromGitter | <gogolxdong> How to remove an element from sequence? |
| 22:59:17 | lqdev[m] | gogolxdong: `delete` if you want to keep the order, `del` if you want )(1) complexity |
| 22:59:24 | lqdev[m] | s/)/O |
| 22:59:51 | lqdev[m] | if you want a particular element, use `find` in conjunction with one of the above |
| 23:00:13 | lqdev[m] | keep in mind that `find` returns -1 if the element can't be found |
| 23:01:17 | lqdev[m] | so be sure to check for that to not generate an exception |
| 23:07:17 | FromGitter | <gogolxdong> more than excepted, thanks ! |
| 23:08:42 | FromGitter | <awr1> also `pop()` if its at the head |
