04:40:29FromGitter<citycide> is a macro capable of something like dart's cascade operator? it'd need a different token obviously because `..` is the slice operator. for the unaware, the cascade operator is a chain of expressions / assignments all acting on the initial value, and returning the initial value at the end.
04:41:29FromGitter<citycide> more on dart's cascades: http://news.dartlang.org/2012/02/method-cascades-in-dart-posted-by-gilad.html
04:55:46FromGitter<citycide> adam12: if you mean a seq of tuples and you want to match exactly, you can use `find`, ie. `someSeqOfTuples.find(("one", 2))`. otherwise I think you'll want to iterate over it if you're looking for only partial equality

05:23:38Araqmakes for a good introduction into Nim's macro system

05:26:25FromGitter<citycide> @Araq: that was my plan exactly, for learning the macros and Nim itself
05:27:31Araqto make it more interesting you can also support cascade(a(), b(), c())
05:29:25FromGitter<citycide> I'll play around on it for a bit

07:46:00FromGitter<Bennyelg> hash("some password") gives me negetive string, is it ok?
07:49:51euantorUse bcrypt, same as the nimforum. There are two options: https://github.com/flaviut/easy-bcrypt or https://github.com/ithkuil/bcryptnim
07:50:01euantorNeither have been updated in a while unfortunately
07:50:10FromGitter<Bennyelg> thanks\

07:54:26FromGitter<Bennyelg> :( just wanted to hash my users password :D
07:58:53Araqwe need a pure Nim bcrypt library and add it to the stdlib
08:05:45FromGitter<Bennyelg> Yea, I wish my knowledge on nim was better to contribute
08:15:53FromGitter<Yardanico> Araq: will karaxdsl be separated as a different module to use it instead of htmlgen?
08:16:20AraqI have no plans to do that, 'nimble install karax'

10:40:37FromGitter<Jipok> Option?
10:40:47FromGitter<Bennyelg> what do you mean :]
10:40:49FromGitter<Bennyelg> example
10:41:04FromGitter<Jipok> http://devdocs.io/nim/options
10:42:23FromGitter<krux02> @Bennyelg I recommend variant type
10:42:49FromGitter<Bennyelg> explain :] ⏎ (BTW: the option is not good for me in this case)
10:43:03FromGitter<krux02> you need a type that is either a User or an error message why you don't have a user
10:43:21FromGitter<krux02> in Rust there is a Result type in the standard library for exactly this case
10:43:38FromGitter<Bennyelg> Oh I see
10:43:39FromGitter<krux02> Result[User] would either be a user or an error message
10:43:39FromGitter<Bennyelg> Nice
10:43:51FromGitter<Bennyelg> Now you refreshed my mind
10:44:09FromGitter<krux02> sadly there is no Result in the nim standard library, but it would be easy to write one

10:46:15FromGitter<krux02> you should not do User | string in this case
10:46:38FromGitter<Bennyelg> Because I can't actually handle the returned type properlly?
10:46:56FromGitter<Bennyelg> I liked you example Im going to adopt it

10:57:01dom96Not a big deal, just notice this mistake a lot and think it's good to make you aware of it.
10:57:07FromGitter<Bennyelg> And I paid the full price, And I would do it again any case this is one of the fewest books I really enjoyed

10:57:54FromGitter<Bennyelg> dont eliminate this idea, just start to write :P
10:58:17FromGitter<krux02> @dom96 I don't know lldb since I use gdb, but I guess it has an equivalent of rbreak that is especially useful for nim
10:58:41FromGitter<krux02> ``rbreak foobar`` breaks on all functions containing "foobar"
10:59:21FromGitter<Bennyelg> @Arne, How do you instantiate Result variable ?

11:05:49dom96fixed
11:05:51FromGitter<krux02> @Bennyelg: when you solved your problem with the result type, you probably should use a Table[string, User]
11:05:59FromGitter<andreaferretti> your `Result` type is generic
11:06:05euantorNice one
11:06:06FromGitter<Bennyelg> oh
11:06:10FromGitter<Bennyelg> yea I need add[T]
11:06:11FromGitter<andreaferretti> you need to return `Result[User]`
11:06:12FromGitter<Bennyelg> to my method
11:06:49FromGitter<krux02> oh yea sorry my bad I forgot that Result needed a generic parameter, but why did it work then?
11:06:55FromGitter<Bennyelg> Works
11:06:58FromGitter<Bennyelg> like lolipop
11:06:59FromGitter<Bennyelg> thanks
11:07:40FromGitter<krux02> this is weird on my system it works without the generic [User] ...

11:07:59FromGitter<Bennyelg> wait to 1.
11:08:31FromGitter<ephja> it's inferred from the body?
11:08:50FromGitter<ephja> I dunno if that's a good thing or not
11:09:22FromGitter<krux02> completely unrelated random post. I now have an Everdrive for my Gameboy Color :P I am thinking if I should invest some time to try writing a Gamboy game in Nim :P
11:09:41FromGitter<krux02> my random guess would be, that it would a huge time sink
11:10:01FromGitter<Jipok> How nim determines that T = User. Looks at the further use of result?
11:10:52FromGitter<krux02> @ephja generally yes, but as long as this behavior is not explicitly documented an how it works and what the rules are, it scares me more
11:11:37FromGitter<Bennyelg> After I return the result of Result[user]
11:11:40FromGitter<krux02> then I wuold prefer an error message like "you need to add the generic parameter '[User]' here"
11:11:48FromGitter<Bennyelg> How Do I actually the the user data
11:12:15FromGitter<krux02> you access is with ``value``
11:12:36FromGitter<Bennyelg> I thought i can but nop I should * the value right?
11:13:43FromGitter<Bennyelg> Yea
11:13:46FromGitter<Bennyelg> works like charm
11:13:50FromGitter<krux02> ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=59d370edb20c642429b8ce5b]
11:15:56FromGitter<alehander42> @krux02 I don't believe Result without T worked with your program, but maybe you didn't call your `[]` so Nim just didn't have to instantiate it and that's why no error
11:16:18FromGitter<krux02> yes I did not use it
11:16:49FromGitter<alehander42> yep ⏎ ⏎ ```proc a: Result = ⏎ result.hasValue = true ⏎ result.value = 2 ⏎ ⏎ # discard a()``` ⏎ ⏎ it works like this because nothing is actually generated, if you have the discard a() it will give an error [https://gitter.im/nim-lang/Nim?at=59d371a101110b72316f0ce3]
11:19:13FromGitter<alehander42> which is fun because you can write ⏎ ⏎ ```proc a: Result = ⏎ result.h = true + 2``` [https://gitter.im/nim-lang/Nim?at=59d37231210ac269209fea84]

11:34:27FromGitter<alehander42> why is it generic?
11:35:08FromGitter<BigEpsilon> because I want to import the enum from cpp header
11:35:09FromGitter<alehander42> @Bennyelg you can't just run a script compiled for browser, you have to include it in your html with e.g. <script>
11:35:25FromGitter<BigEpsilon> and the enum is nested in a templated class
11:36:19FromGitter<BigEpsilon> example: ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=59d3763301110b72316f27b8]
11:37:24FromGitter<Bennyelg> @alehander42 and than what
11:37:29FromGitter<Bennyelg> how to I pack it
11:45:25FromGitter<krux02> that is something I don't know, sorry
11:46:10FromGitter<krux02> @BigEpsilon this is the first time I see a generic parameter at an enum
11:46:35FromGitter<krux02> and is c++ you can't have template parameters on enums
11:46:44FromGitter<krux02> so maybo your [T] is wrong
11:47:56FromGitter<krux02> ah I get it, it is Foo that has the generic parameter, and Deep Enum just happens to be inside of it
11:50:10FromGitter<ephja> interfacing with C++ seems like fun :-)

11:58:46planetis[m]about the post: rst documentation says double backticks for code but nim doc produces bold. Is it a bug?
11:58:48FromGitter<krux02> I open the index.html from chromium
12:04:04FromGitter<BigEpsilon> @krux02 , yes it is only to interface with C++

12:04:45FromGitter<BigEpsilon> maybe @Araq can hint me
12:06:40FromGitter<krux02> @BigEpsilon I am not 100% sure, but my guess is that you hat a c++ feature that is not simply mapable to nim. Is it possible to modify the c++ code or write some glue code, so that you don't have an enum in a templated class anymore?

12:15:59FromGitter<Varriount> @krux02 My phone gets 44 fps. :3
12:16:04FromGitter<ephja> hmmm always 50 fps
12:16:27FromGitter<krux02> yea I know my computer 3D rendering is super slow
12:16:38FromGitter<ephja> and then firefox hung when I switched to another tab. well, that should improve eventually
12:17:35FromGitter<krux02> eventually I hope I can write an sdl app and simply change from "nim c -r" to "nim c -wasm -r"
12:17:44FromGitter<krux02> and it will be executed
12:18:45FromGitter<krux02> @Jipok how do you launch the generated index.html?

12:19:09yglukhov_also will start your browser with the build
12:19:22FromGitter<Jipok> with some restrictions. Browsers do not yet support multithreading for wasm.
12:19:40FromGitter<krux02> I don't need multithreading
12:19:50FromGitter<Jipok> @krux02 just open it

12:20:19FromGitter<krux02> yea opening it result in the error shown to you
12:20:36FromGitter<BigEpsilon> @krux02 , I'm implementing that in c2nim, so it will be better if I can make it work
12:20:45FromGitter<krux02> it is a security mechanism that prevents accessing local files

18:24:49FromGitter<Yardanico> @Bennyelg just use karax :)
18:24:52FromGitter<ephja> @Bennyelg 'add' takes 2 arguments
18:25:08FromGitter<Bennyelg> @Yardanico i WILL EVANTUALLY
18:25:45FromGitter<ephja> either add more calls to 'add' or concatenate strings with &
18:25:58vivusdom96: is your framework still the go-to for web-apps?
18:27:41dom96I'd say so
18:29:08AraqI agree.
18:29:32*Jesin joined #nim
18:29:46*TjYoco joined #nim
18:30:37CalinouI remember Jester having performance bottlenecks, is this still the case?
18:30:56*PMunch joined #nim
18:31:07*nsf joined #nim
18:31:19Araqmost of these bottlenecks are in Nim's stdlib
18:31:59Calinouthat kind of sucks… this means that most complex programs won't be fast
18:32:15Araqfile uploads and downloads used to be really super bad, now they are ok'ish, I hope?
18:32:20vivus"fast" is relative, as I assume jester is 'faster' than Flask
18:32:27Calinousurely it is, yeah
18:32:50CalinouI've only done back-end development in CodeIgniter/Django/Symfony myself :P
18:33:01Araqthe stdlib needs to use 'sendfile' but doesn't. PRs welcome
18:33:07Calinouhaven't really tried the lower-end options, I found them too cumbersome to use
18:33:18Calinou(lack of docs/community resources is also a big problem)
18:33:20vivusCalinou: whatever pays the bills. PHP gets loads of flack, but it runs more sites/apps than Go ever will
18:33:29Calinouvivus: true, PHP is not that bad if you follow good practices
18:33:34Calinouand it can be fairly speedy, too
18:33:43Calinou(not quite as fast as Go, but "fast enough" for a lot of use cases already)
18:34:24vivusDoes anybody use vim with auto-complete for nim?
18:34:32PMunchvivus, I do
18:34:45PMunchOr, well I'm not sure if I've got auto-complete..
18:34:51vivusPMunch: which vundle-plugin do you use?
18:34:55*endragor joined #nim
18:35:15PMunchzah/nim.vim
18:35:20PMunchAnd scroolose/syntastic
18:35:31PMunchThose are the only ones I've got for Nim I think
18:35:49FromGitter<BigEpsilon> I couldn't find a vim plugin thats support nimsuggest
18:36:20FromGitter<BigEpsilon> VS code is better in that regard
18:36:52PMunchhttps://medium.com/@caspervonb/why-i-still-use-vim-67afd76b4db6?h
18:37:02PMunchYes, but VC code is horrible in pretty much anything else..
18:37:46FromGitter<BigEpsilon> vim+tmux FTW
18:37:49vivusI saw a nimsuggest wrapper for vim like the other day
18:38:03*gokr joined #nim

18:39:08*endragor quit (Ping timeout: 240 seconds)

18:39:43vivushttps://github.com/BitR/ycm-nimsuggest
18:39:43FromGitter<ephja> they seem broken on windows though
18:39:47PMunchThat's my buffer navigation bindings
18:39:54FromGitter<BigEpsilon> I tried neovim terminal
18:40:03FromGitter<BigEpsilon> but I prefer tmux
18:40:24vivuscompilation from within neovim?
18:40:35FromGitter<BigEpsilon> no need for extra keys strokes to enter/exit insert mode
18:40:57FromGitter<BigEpsilon> and I can save my entire workspace with tmux
18:41:10FromGitter<BigEpsilon> attach/detach
18:43:58FromGitter<ephja> vivus: yes, in a single quadrant for example
18:44:41FromGitter<ephja> that's the only thing I've wanted it for
18:44:42FromGitter<Jipok> Why does everyone choose between vim and vscode? Why not Sublime Text?
18:45:35miran"VS code is horrible in pretty much anything else" -> PMunch, what do you mean by that? i use VS code regularly and don't feel like it is horrible
18:45:48FromGitter<Jipok> electron
18:45:59FromGitter<ephja> doesn't bother me
18:46:25PMunchmiran, check the link I sent
18:46:26FromGitter<ephja> what does is the fact that you can't have a symbol browser next to the editor for example
18:46:33PMunchHogs memory like there's no tomorrow
18:47:17PMunchAnd the sum of all those tiny inefficiencies than front-end devs like to sweep under the rug adds up
18:47:26dom96it doesn't for me
18:47:30dom96Using 63mb right now
18:47:30miranPMunch: i've read that before, but it didn't convince me it is horrible ;)
18:47:35PMunchNoticed a drastic boost in battery life after I switched to vim as well, which is always nice :)
18:47:49PMunchThe horrible part was a bit tongue in cheek
18:47:50dom96oh wait, there is a bunch of "Code Helper"s
18:48:03miraneh, i use desktop, so i have no idea about battery life
18:48:07PMunchIt's not horrible, just horribler than vim :P
18:48:24vivusVSCode is an Electron app?
18:48:28FromGitter<Jipok> +
18:48:33FromGitter<ephja> it used about 500mb when I worked on the compiler and a few other things. I don't think the CPU usage was high
18:48:52ipjk63 mb isn't that bad
18:49:02PMunchvivus, yup
18:49:13dom96ipjk: nah, I'm wrong, it's way more than that
18:49:23vivuseven sublime is better than electron-apps
18:49:24ipjkMy emacs is running at 50 with all the files in lib/nim open
18:49:25miranPMunch: i'm vim noob, so i'm much more productive in vs code
18:49:33dom96But I've got 16GB, doesn't bother me
18:49:42PMunchOh yeah, that's definitely a factor miran :P
18:49:58miranand more memory consumption doesn't bother me, for the same reason dom96 just mentioned :)
18:50:16PMunchBut with a tiling WM and good keybindings in Nim I can blaze through all kinds of tasks in a jiffy
18:50:20FromGitter<ephja> it doesn't result in all the RAM being used, but unnecessary bloat still bothers me
18:50:22dom96I tried getting into vim. It simply has too many irregularities, VS Code is at least consistent with the rest of my OS...
18:51:01mirani started to use vim keybindings in vs code. so far - very nice experience
18:51:14FromGitter<Jipok> But using such software you support it. So it's not a matter of consumed memory.
18:51:15FromGitter<ephja> "Code requires a whopping 349 megabytes in order to open a 60 byte file" hmmm
18:51:57PMunchYeah, I would guess the 60 byte file accounts for about 60 bytes of that total :P
18:52:43FromGitter<ephja> doesn't correspond to dom's experience at all then
18:53:11ipjk349 isn't really that much in this day and age
18:53:23dom96Like I said, I was wrong about its memory usage.
18:53:28vivusthe only editor that matters is the 1 Araq uses XD
18:53:32FromGitter<ephja> ok
18:53:38PMunchipjk, still it's quite the overhead..
18:54:17miranwhat use is of 16GB of ram, if you constantly have 15GB free? ;)
18:54:23dom96^^
18:54:43vivusis anybody familiar with a reddit SPA? I don't see any on GH that I could build a Jester API for
18:54:46FromGitter<ephja> @Jipok well, I haven't mentioned it to that many people, so not much harm done :p
18:54:58PMunchSPA?
18:55:03vivusmiran: your chrome browser needs 2GB to see stackoverflow
18:55:04FromGitter<Yardanico> API maybe ? :)
18:55:14vivusPMunch: Single Page Application
18:55:17miranvivus: :)
18:56:20PMunchAah
18:56:28vivusI don't really like JS with all its fancy frameworks though ಠ_ಠ
18:56:45ipjkWhat's more to discuss about electron-based applications, are their filesize
18:58:55miranwould i like that vs code is lighter/faster? yeah. would i like it so much that i'm ready to pay $80 for sublime? hell no.
18:59:02FromGitter<Yardanico> well also they're too heavy :(
18:59:05FromGitter<Yardanico> sublime is three
18:59:06FromGitter<Yardanico> *free
18:59:08FromGitter<Yardanico> all dev builds are
18:59:14PMunch"Free"
18:59:28PMunchIsn't it the same kind of free as WinRAR was?
18:59:58ipjk"Sublime Text 3 dev builds are currently available to licensed users only."
19:00:01miranwell, i don't want to constantly see popups to remind me i could pay for it
19:00:09planetis[m]With the latest Ast changes in nim you may need to create a StmtList for the result.
19:00:37miranand community/extensions seem on vsc side too
19:01:05ipjkAslong as users are happy with editor x, it doesn't really matte.
19:02:07vivusmiran: same can be said for electron, neovim, emacs and sublime

20:20:59FromGitter<krux02> there is nimcache
20:21:43FromGitter<krux02> that error means that you have an expression that is not used for anything

20:22:07onionhammer${ statement } vs $( expression )
20:22:22FromGitter<krux02> you can sinlence it with a ``discard`` around that expression, but it is still code smell
