03:52 <FromGitter> <exts> Is there a way to pass backslashes to a string without having to escape the backslash? I basically want it to ignore the default functionality that denotes certain characters so I can make cleaner dynamic regex strings. ⏎ ⏎ eg.: %([A-Za-z]+\\-\\d+) to be a bit nicer -> %([A-Za-z]+\-\d+) ⏎ ⏎ Is that possible in crystal?

16:23 <RX14> Papierkorb, thats really cool

16:33 <Papierkorb> I'm wondering about the guy who started coding an MMORPG server in Crystal

16:33 <Papierkorb> Sucks that you can't really use that kind of project on your resume heh

16:35 <RX14> i love having `crystal tool format`, I cna just write code then :w and then it looks nice

16:35 <RX14> i really should get around to sorting out emacs crystal-mode though

16:35 <RX14> because it is not particularly up to date

16:35 <RX14> or bug-free

16:36 <RX14> for example %() doesn't work, so I have to do # " sometimes to close unmatched " in %()

16:36 <Papierkorb> lol

16:37 <Papierkorb> I should learn emacs again I guess, for all the times I hate atom-editor...

16:37 <RX14> i switched to spacemacs a couple of months ago and i've been loving it

16:37 <Papierkorb> How's it different?

16:37 <RX14> vim plugins used to break and stuff but spacemacs has been solid

16:38 <Papierkorb> oh spacemacs was vim esque

16:38 <Papierkorb> ?

16:38 <RX14> i love being able to install the ruby layer and it's basically all the ruby plugins you could ever need

16:38 <RX14> spacemacs is emacs +evil at it's core

16:38 <RX14> so emacs with vim bindings

16:38 <RX14> but it adds community-maintained crystal layers

16:39 <RX14> sorry

16:39 <RX14> plugin layers

16:39 <Papierkorb> Ah GPLv3

16:39 <RX14> i'm tired...

16:40 <RX14> but the thing I like most is emacs stuff like dired, tramp, and all that

16:41 <RX14> also it works well across multiple monitors

16:41 <RX14> which vim does not

16:41 <RX14> so emacs has been a huge win for me

16:41 <FromGitter> <mjago> @RX14 I would be interested in emacs-crystal-mode

16:41 <Papierkorb> I don't like vim, hitting escape instead of some key combo never made sense to me, so I'd have to use emacs anyway lol

16:42 <RX14> you don't like modal editing?

16:42 <RX14> or you don't like esc?

16:42 <Papierkorb> I don't like that you have to switch modes

16:42 <RX14> i like it

16:42 <Papierkorb> Stuff like finding a line of text should be just a single keypress away

16:42 <Papierkorb> And I have more than 8MiB of memory, so emacs is fine :P

16:43 <RX14> its quicker to type jk and use hjkl than move my fingers to the arrow keys for me#

16:43 <RX14> plus i'm always using w and such movements anyway

16:44 <Papierkorb> never liked that, before I'd go with that I'd rather use the Neo keyboard layout instead, I guess that'd result in a bigger speedup

16:45 <RX14> well spacemacs just has vim keybinds as a default

16:45 <RX14> you can turn them off and use regular emacs keybinds if you want

16:45 <Papierkorb> I'm more surprised that spacemacs isn't in the AUR

16:45 <RX14> it's an emacs distribution

16:45 <RX14> you clone it into your ~/.emacs.d/

16:45 <RX14> so you just install emacs

16:45 <Papierkorb> Ah

16:47 <RX14> emacs-crystal-mode has changed hands about 10 times lol https://github.com/ggiraldez/emacs-crystal-mode/network

16:47 <RX14> its a mess

16:48 <Papierkorb> and in such a short time span too

16:48 <RX14> yeah

16:48 <RX14> i guess TechMagister is the latest

16:48 <RX14> i should learn elisp

16:49 <RX14> oh wow it's returned to it's second owner it's a miracle https://github.com/dotmilk/emacs-crystal-mode

16:52 <unshadow> Anyone with some experience in Nerual Networks ? I'm trying to create a NeuralNet in Crystal but having some issues

17:10 <FromGitter> <david50407> What does "The Nil type is used to represent the absence of a value, not unlike null in other languages. " mean in the document?

17:10 <FromGitter> <david50407> Nil is like null in other languages? or unlike

17:10 <FromGitter> <david50407> (the "not unlike" part confuses me)

17:12 <Papierkorb> nil usage is roughly null in C-style languages like C, C++, Java or C#

17:13 <Papierkorb> But its semantics are vastly different, `nil` is the only instance of `Nil`, thus, nil is typed, where in those language, null exists for all objects implicitly

17:14 <FromGitter> <david50407> Oh I know what it means, thx

17:14 <FromGitter> <david50407> :D

17:16 <RX14> it's a double negative, "not unlike" is like "like" but it has slightly different connotations

17:27 <FromGitter> <david50407> Is "like" but not that "like", right? lol

22:35 <wmoxam> hrrm, undefined constant LLVM::DIFlags::Zero

22:36 <RX14> wmoxam, are you compiling with the latest crystal?

22:36 <wmoxam> yeah

22:36 <RX14> hmm

22:36 <RX14> 0.20.3>

22:36 <RX14> oh

22:36 <wmoxam> compiles ok on OSX, not on OpenBSD

22:36 <RX14> that reminds me

22:37 RX14 changed the topic of #crystal-lang to: The Crystal programming language | http://crystal-lang.org | Crystal 0.20.4 | Fund Crystal's development: http://is.gd/X7PRtI | Paste > 3 lines of text to https://gist.github.com | GH: https://github.com/crystal-lang/crystal | Docs: http://crystal-lang.org/docs/ | API: http://crystal-lang.org/api/ | Logs: http://irclog.whitequark.org/crystal-lang

22:37 <RX14> wmoxam, thats weird

22:37 <wmoxam> I don't see anything that should make that enum dependant on LLVM version

22:37 <RX14> well

22:37 <wmoxam> which was my first thought

22:38 <RX14> openbsd isn't on CI

22:38 <RX14> (yet)

22:38 <RX14> so its a bit flakey

22:48 <wmoxam> I dunno that it's fair to call it 'flakey' :D

22:49 <wmoxam> it does spit out some warnings due to lib usage

23:06 soveran has quit [Remote host closed the connection]

23:08 <RX14> wmoxam, well it's flakey in that any PR could break openbsd at any time and we wouldn't know

23:08 <RX14> until someone complained

23:08 <RX14> i'm glad someone's using it though

23:08 <RX14> so we have someone to complain :)
