01:47 <crystal-gh> crystal/master 5c93802 Ary Borenszweig: More syntax updates

01:47 <crystal-gh> crystal/master cf019e2 Ary Borenszweig: Fixed #2050: Regression with closures

01:51 <greyblake> Hi, there is implementation of JWT (JSON Web Tokens) for Crystal: https://github.com/greyblake/crystal-jwt

01:55 <travis-ci> manastech/crystal#cf019e2 (master - Fixed #2050: Regression with closures): The build is still failing. https://travis-ci.org/manastech/crystal/builds/104374092

12:00 <ytti> if repos.class == Hash

12:00 <ytti> puts repos.keys

12:00 <ytti> end

12:00 <ytti> why does this not know compile time, that it's hash?

12:00 <ytti> it seems bit awkward to traverse YAML document

12:00 <ytti> as i'll need stuff like

12:00 <ytti> if x.class == Hash

12:00 <ytti> puts (x.class as Hash).keys

12:00 <ytti> end

12:00 <ytti> seems redundanat

13:24 <ytti> do i really need to re-iterate the hash structure every time? https://gist.github.com/anonymous/6079ba1a94dfb0fac629

13:24 <ytti> lines #4 and #6 seem redundant

13:24 <ytti> definition seems redundant, i should be just able to intansiate it, based on previous def

13:45 <ytti> http://crystal-lang.org/api/YAML.html what would YAML.mapping look like, if type is Hash and you need to define mapping under that Hash?

15:30 <crystal-gh> [crystal] f opened pull request #2053: Assignment with if doesn't need assignment. (master...master) https://git.io/vzoQ9

15:38 <crystal-gh> [crystal] asterite pushed 5 new commits to master: https://git.io/vzo7K

15:38 <crystal-gh> crystal/master 385900d Ary Borenszweig: Simplified GC.add_finalizer

15:38 <crystal-gh> crystal/master 862ccfc Ary Borenszweig: Use free var in Enumerable#in_groups_of

15:38 <crystal-gh> crystal/master 2367653 Ary Borenszweig: Removed the `::` syntax for type declarations and uninitialized variables

15:46 <travis-ci> manastech/crystal#938a083 (master - The `record` macro can now accept type declarations): The build is still failing. https://travis-ci.org/manastech/crystal/builds/104449644

16:04 <unshadow> So, just wanted to make sure I'm geting the changes to Socket.read, lets say I want a blocking read, and want to read(1024), how do I do it ? I see that read only accepts Uint8

16:27 <jhass> unshadow: iirc you can just pass it a slice of that size

16:30 <unshadow> jhass: Like Slice(UInt8).new(1024) ?

16:30 <unshadow> read(Slice(UInt8).new(1024))

16:30 <jhass> not sure it returns it, but yeah

16:31 <unshadow> >> a = Slice(UInt8).new(1024)

16:31 <DeBot> unshadow: # => [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, ... - https://carc.in/#/r/qdr

16:31 <unshadow> how would I convert the data back to String afterwords ?

16:32 <unshadow> Slice supports to_s ?

16:32 <ytti> there is no File.readline, is it possible to figure out where symlink links to?

16:32 <unshadow> I see it does

16:39 <jhass> unshadow: pass it to String.new

16:47 <unshadow> jhass: I'll work on it, thanks for the heading :)

16:55 <Ox0dea> asterite: Do you mind my asking the source of your avatar?

17:37 <smarr> hi, brief question, Crystal uses the Boehm GC, as per http://crystal-lang.org/2013/12/05/garbage-collector.html?

17:37 <BlaXpirit> smarr, i think so

17:38 <BlaXpirit> smarr, yes

17:38 <BlaXpirit> i'm saying this based on this list of dependencies (first in the list) https://www.archlinux.org/packages/community/x86_64/crystal/

17:40 <smarr> BlaXpirit: ok, great, thanks

19:27 <jeromegn> what’s the best practice for hash key types? symbols or strings?

19:29 <jeromegn> *hash keys type

19:43 <BlaXpirit> jeromegn, this isn't about practice, this is about what's viable and what isn't

19:43 <BlaXpirit> if it is possible to use symbols in some case, then sure, use them

19:44 <BlaXpirit> jeromegn, but that also indicates that you probably shouldn't be using a hash in this case at all

19:44 <crystal-gh> [crystal] asterite pushed 2 new commits to master: https://git.io/vzKqc

19:44 <crystal-gh> crystal/master a3f262a Ary Borenszweig: Fixed: missing virtual type check in union type declaration

19:44 <crystal-gh> crystal/master 93d5d7e Ary Borenszweig: Fixed #2057: regression with block vars and macros

19:44 <jeromegn> it’s an options Hash on initialization

19:44 <jeromegn> enlighten me :)

20:03 <crystal-gh> crystal/master 1e6f385 Ary Borenszweig: Fixed #2054: can't format heredoc in some cases

20:12 <ytti> grumble, why is compiling static binaries so hard

20:12 <travis-ci> manastech/crystal#1e6f385 (master - Fixed #2054: can't format heredoc in some cases): The build passed. https://travis-ci.org/manastech/crystal/builds/104486848

20:18 <ytti> sigh can't compile crystal on osx

20:18 <ytti> other than from brew

20:19 <asterite> jeromegn: if it was an options hash on initiailzation, and that came from Ruby, you probably want named arguments: http://crystal-lang.org/docs/syntax_and_semantics/default_and_named_arguments.html

20:19 <jeromegn> oh

20:19 <jeromegn> nice

20:19 <jeromegn> that could be a long list though :)

20:20 <jeromegn> playing around making a native (not dependent on external libs) MongoDB driver in crystal

20:20 <jeromegn> just trying to send a first correct message at the moment

20:26 <ytti> tried to add readlink to file.cr, but can't compile to test if it works

20:27 <ytti> hopefully will get leehnox box back up next week

20:27 <ytti> so frustrading to work on osx :(

21:00 <ytti> there should be like community sanctioned support for money page, i'd pay for someone to figure out how to compile this statically

21:09 <crystal-gh> crystal/master eee3eff Ary Borenszweig: Fixed #2059: regression with class variables not being correctly typed

21:18 <travis-ci> manastech/crystal#eee3eff (master - Fixed #2059: regression with class variables not being correctly typed): The build passed. https://travis-ci.org/manastech/crystal/builds/104495765

21:18 <DeBot> https://github.com/manastech/crystal/issues/2059 (Segfault for default class variable in crystal 0.11.0)

21:39 <BlaXpirit> hm I'm so lucky that my project in crystal didnt break

21:40 <BlaXpirit> one of the last changes I made just happened to replace the :: thing with something else

21:42 <BlaXpirit> waaaait a second, no I didn't replace it

21:42 <BlaXpirit> why does this work https://github.com/BlaXpirit/crsfml/blob/master/src/common_obj.cr#L33

21:51 <yxhuvud> urgh. It would be convenient sometimes if it was allowed to pass self before instantiating all non-nilables if the receiver never called any methods on it.

22:08 <ytti> i think we need more community/collaborate approach to docs

22:09 <ytti> what if API doc would include expandable section for code examples, with arrow up/down voting, to see which order they appear

22:09 <ytti> i think over time, examples would cover issues which confuse users

22:10 <ytti> also, maybe doc bounties? I'd pay 50eur on the spot, if someone can tell me how to compile (reasonably) static binary on osx

22:31 <asterite> ytti: did you check this? https://github.com/manastech/crystal/issues/2003

22:39 <ytti> i did, but that was after I had given up and already given up, and already half way through consolation rosé, so my take away from it was only 'bugger, it's not gonna be easy'

23:24 <mondok> i have array of objects

23:25 <mondok> and try to find one element

23:25 <mondok> but seems "find" doesnot work

23:25 <mondok> and "select{}.first" works good

23:26 <mondok> where is problem?
