01:16:33FromGitter<mraxilus> nor I most of the time, with the bridges to IRC on most servers, It's mostly just a fancier front end with a bunch of other benefits not limited to voice
01:16:51FromGitter<mraxilus> but that's okay, I can just open up gitter for nim related things
01:17:31FromGitter<mraxilus> just would've been convenient if there was a bridge already.
01:18:21FromGitter<mraxilus> also, @libman are you a lesswronger by any change?

04:38:35ibkis there an example to use `to` from marshal module?
04:38:36ibkI tried this code:
04:38:36ibkvar user: User
04:38:36ibk user = to(req.body)
04:38:36ibkbut i got "Error: cannot instantiate: 'T'"

05:52:42ibkAraq : thanks, but why the example in http://nim-lang.org/docs/tut2.html#generics don't need the `[User]`?
05:59:02ibkwhich one we should use to marshal an object into JSON string. using `marshal` module or `json` module? Both module work fine for my case
05:59:05FromGitter<endragor> @ibk: the generic params in those examples can be inferred from the context. in your case the compiler has no idea what you’re trying to deserialize the string into, so you have to tell it
06:01:39FromGitter<endragor> hmm, actually, it can potentially be inferred in your case, too, since there is user on the left. not sure then :)
06:02:34ibkmarshal module is easier, i wonder if this ease comes with price
06:05:29*nsf joined #nim
06:35:46*Arrrr joined #nim
06:46:54flyxallowing to derive the generic type from the variable that the result is being assigned to would make the grammar undecidable.

10:04:05FromGitter<endragor> it should be picked up wherever `nim.cfg` gets picked up afaik
10:09:10cheatfateyglukhov, you can put it in your project directory, `config.nims` - asyncdispatch patch will be applied for all files in directory, 'somename.nims' - asyncdispatch patch will be applied for `somename.nim` file only
10:10:09yglukhovendragor, cheatfate: cool, thanks
10:11:08*HakanD___ joined #nim
10:14:02cheatfateyglukhov, why you switching?
10:14:44yglukhovcheatfate: just want to make sure im ready =))
10:15:43cheatfateyglukhov, i don't believe it replaces current asyncdispatch in future
10:16:17yglukhovcheatfate: what? why? oO
10:16:55cheatfatei think everybody likes `upcoming` :)
10:17:32yglukhovcheatfate: err... is that a joke or smth? =)
10:17:34Araqwe can remove the one in lib/pure
10:17:52Araqand keep it in upcoming forever so people don't have to adapt their configs
10:18:21yglukhovwhy not just switch to it altogether? does it break anything?
10:20:44cheatfateyglukhov, upcoming asyncdispatch is more pure, then current, so it can cause errors/exceptions if your code uses some current asyncdispatch hacks
10:21:13cheatfateor doing something really wrong
10:21:20cheatfatethis is only difference
10:21:33Araqyglukhov: yeah, I'm kidding, we'll switch properly
10:21:52Araqonce we tested Nim forum and stuff with upcoming
10:22:17yglukhovcool. is nim forum using upcoming already?
10:22:53cheatfateyglukhov, i dont think so :)

20:34:27jh32is it possible to have something like an array of static[int] as type parameter, i.e: var m: MyType[[1,2,3]] ?
20:35:28*djellemah_ quit (Ping timeout: 245 seconds)
20:37:06Araqgood question. I think static[T] is mostly tested with ints
20:37:12jh32i'm thinking about how one would model the Network class from https://github.com/mnielsen/neural-networks-and-deep-learning/blob/master/src/network.py in nim
20:37:58jh32if that would be possible one could have all the matrices statically sized
20:38:43AraqI fail to see the connection
20:40:22Araqthe Python code doesn't seem to require such a thing
20:41:19jh32the Python code does it all dynamically which would be possible with seq's in nim, but array would be cooler, no?
20:45:22jh32these np.random.randn() calls in __init__() create arrays with dimensions depending on the compile time available sizes array
20:46:54jh32maybe it's more pragmatic to use seq
20:48:46AraqI usually use a flat seq, not a nested seq and do the indexing arithmetic on my own y*row+x
20:49:18Araqserved me well and you can cheat and use a single for loop for when the dimensions don't matter
20:49:30Araqwhich can happen quite often.
20:51:28jh32i'll try that, thanks

21:28:46dycei am curious if using nim to control gnu libmicrohttpd would make any sense

21:43:49*bjz quit (Quit: My MacBook Pro has gone to sleep. ZZZzzz…)
21:45:36dyceAraq: i'll start looking into it. libmicrohttpd i assume is the best performing library for web?
21:46:23*bjz joined #nim
21:46:38Araqsure it contains 'lib' and 'micro', what could possibly be faster?
21:47:22ldleworklibnanohttpd obviously
21:48:42Araqno idea why never ending cascades of 'if (err) goto error' in C land are considered the "fastest way to program things", but then C programmers live in their own world anyway

21:51:11Araqldlework: lol
21:51:51dom96Don't forget about https://github.com/h2o/picohttpparser
21:55:34def-Araq: because branch prediction works well for those?
21:56:46Araqthat's more code bloat than proper exceptions and your icache is not as effective as it could be
22:12:16*Trustable quit (Remote host closed the connection)
22:18:01cheatfatedyce, i dont think this library is the best performing... looks like it knows only `epoll` and nothing more...
22:20:14dycecheatfate: https://github.com/nanoant/WebFrameworkBenchmark , looks like Kore is faster https://kore.io/
22:25:37dom96what are you writing that needs to give such fast responses?
22:28:18cheatfatedyce, all this benchmarks are piece of shit and there so many `semi official` benchmarks and i think even more `official` benchmarks which put one framework to be better then others...
22:28:57dycecheatfate: true
22:29:30cheatfatedyce, as i said before libmicrohttpd knows only `epoll` so run same benchmark on freebsd/macos/openbsd/netbsd/xxxbsd which uses `kqueue` and libmicrohttpd will be in last positions
22:29:42cheatfatei think maybe a little better then apache
22:31:40cheatfateand about Kore, looks like it knows `kqueue` and `epoll` but knows nothing about `eventports` and `completion ports`... so benchmark it on windows and solaris to get `true` results :)
22:32:59dom96I tried to reproduce these benchmark multiple times now and I still cannot.
22:33:34dom96I am probably doing something wrong, but the more I think about it the more useless these benchmarks seem.
22:35:42dom96nimforum is working perfectly well and it's not even running in release mode.
22:36:02dom96but I'm curious about your use case anyway
