03:35:24datSilencerHi. Is this the right place to ask questions about wrapping C headers with c2nim? Thanks!
03:37:21ftsf_datSilencer, probably, best to just ask your question
03:38:14datSilencerok
03:38:32*fastrom quit (Quit: Leaving.)
03:39:01datSilencerSo I'm trying to wrap FMOD's headers, where fmod_common.h has the following (partial) content:
03:39:21datSilencer#if defined(_WIN32) || defined(__CYGWIN__)
03:39:29datSilencer #define F_CALL __stdcall
03:39:38datSilencer#else
03:39:43datSilencer #define F_CALL
03:39:46*nsf joined #nim
03:39:49datSilencer#endif
03:40:13datSilencer... then later, down the header, c2nim finds:
03:40:28datSilencer#ifdef DLL_EXPORTS
03:40:34datSilencer #define F_API F_EXPORT F_CALL
03:40:40datSilencer#else
03:40:45datSilencer #define F_API F_CALL
03:40:50datSilencer#endif
03:41:10datSilencer... that second block of code makes c2nim complain like so:
03:41:26datSilencerfmod_common.h(42, 1) Error: ';' expected
03:41:54ftsf_if you're pasting lots of stuff, please use gist or a pastebin like thing
03:42:05datSilencerah ok
03:42:07datSilencersorry :P
03:42:23datSilencerwell, I mean, that's pretty much it
03:42:48datSilencerso that error makes me think there might be a missing feature in c2nim's preprocessor
03:43:03datSilencerany thoughts or suggestions appreciated. Thanks!
03:43:57datSilencerwould it be better to open a Github issue with a small example?
03:45:19ftsf_it would
03:51:41datSilencerwill do then. Thanks!

07:53:23yglukhovAraq: hi. remember the tables memory leak problem? i suspect, there's still something left, but haven't looked carefully into that. Could be somewhere in rehashing...
07:53:46Araqthere never was a leak
07:54:05Araqthe tombstones are re-used
07:54:19Araqmaybe a bit too slowly and not consistently enough.
07:54:31Araqbut it's always been a weird issue
07:54:38yglukhovthere never was a leak? first step: denial :DD
07:54:55Araqreplace it be robin-hood-hashing
07:55:03Araqit's the superior algorithm anyway
07:55:08Araq*by
07:55:15*bjz joined #nim
07:55:54yglukhovok, so these tombstones could appear as a result of rehashing?
07:55:55*bjz quit (Client Quit)
07:58:37yglukhovok, looks like i'm wrong. rehashing always allocates a fresh sequence.

08:15:23zielmichaIs it possible for converter to have generic return type? Like 'converter fromInt[T](a: int): Foo[T]', so I can assign int to any Foo. (Trying this literally, errors with cannot instantiate: 'T').
08:18:27*akamaus quit (Ping timeout: 264 seconds)
08:19:08Araqzielmicha: no, how could it infer the 'T'
08:22:06zielmichaI don't know :( . In C++ I could use non-explicit constructor, so I hoped that there is something similar in Nim.
08:23:55zielmicha(and in theory compiler could use return type inference to infer T)
08:24:29yglukhovAraq: no, it's not blocking
08:24:35Araq(I hope return type inference never makes it into Nim)
08:25:10Araq(I don't want libraries which make me write 'let x: T = yayOnlyWorksWithColonT' )

11:02:37BlaXpiritif I have a string like " a \t bb c", how can I split it on any whitespace to get @["a", "bb", "c"] ? used to be just .split(), now that gives @[, , a, , , , , bb, c]
11:04:09AraqBlaXpirit: strutils.splitWhitespace
11:05:43BlaXpiritthanks
11:06:56cheatfateAraq, could you please take a look https://github.com/nim-lang/Nim/issues/4475
11:14:28ephjathat's what split does now? hm ok
11:15:11ephjaBlaXpirit: do you still play xonotic?
11:15:24BlaXpiritephja, no
11:16:58ephjaok
11:17:29ephjait's fun, but really difficult to master
11:21:28Araqcheatfate: nice bug
11:21:36ephjawhat would you use if you wanted to have both some other separator and not include it in the result? is that rarely used? I guess so
11:22:17cheatfateAraq, just want to ask, is my syntax wrong?
11:22:47Araqvar t = newStringTable(modeCaseInsensitive) # compiles
11:22:57*bjz quit (Ping timeout: 276 seconds)
11:23:01*bjz_ joined #nim
11:23:05Araqthe syntax is not wrong though, it's some really nasty thing
11:23:16ephjaum. works for me
11:23:27ephjawait
11:23:57ephjathe compilation fails but Aporia runs the cached executable
11:33:22cheatfateAraq, i found my first `showstopper`? :)
11:33:47cheatfatebut its not `showstopper` because it can be avoided...:(
11:34:46ephjahe doesn't need to know that!
11:46:52Araqcheatfate: indeed, showstopper bug worthy.

15:13:02kierCI tests passed, looks like it's ready to be merged
15:18:45Araqthe test only happens to work btw, tests without a "spec" section need to be compilable, nothing more.
15:19:12Araqlook at any other of the trillion tests for how a "spec" section looks like
15:20:13Araq(apologies if you already know this)
15:22:59zielmichaIs it possible to reinsert type retrieved using macros.getType into AST?
15:24:23zielmicha(getTypeInst returns something closest to what seems to be needed, for example BracketExpr Sym "Foo" Sym "byte", but compiler complains "Error: no generic parameters allowed for Foo")
15:24:58zielmicha(if I replace Syms with Idents manually, it appears to work, but this doesn't look like clean solution)
15:26:03kierAraq: ah i've probably misinterpreted what the "spec" section is for
15:27:18kierthe test code should just compile; if it fails to compile, then the bug's been reintroduced
15:28:20Araqyes, that's why I accepted your PR
15:29:04Araqzielmicha: we try to prevent this due to soundness problems

15:37:05chemist69Hi, I am still getting started with Nim. I am currently looking into the tables module and am getting confused by the difference between Table and TableRef. When should I use one over the other?
15:38:59*nsf joined #nim
15:40:00Araqwhen you're after a Python experience, pick TableRef
15:40:40Araqwhen you care about memory indirections and know how to program for speed, pick Table
15:42:30kierif `a` is a Table, and you write `var b = a`, then `b` will effectively be a new table initialised to what the contents of `a` were. changing `b` doesn't affect `a`.
15:43:15kierwhereas if `a` were a TableRef instead, then changes to `b` would still affect `a`. both `a` and `b` reference the same data structure.
15:44:45kierif you don't care too much about speed or memory constraints, then you can choose between Table and TableRef based on which behaviour you want
