06:22 <FromGitter> <elementio:salt-rock-lamp.ems.host> hi crystal people, is there somewhere in the docs that states what you have to `require` in order to use some given data type in the std lib? i just spent 5 minutes being very confused, until i realized that i needed to write `require "json"` in order to use `#to_json`...

06:42 <FromGitter> <Sija> @elementio:salt-rock-lamp.ems.host Usually there’s a `NOTE` re: the `require` (is needed) somewhere at the beginning of the docs for the given module

13:28 <FromGitter> <Groogy> Yo! Is there a short hand for comparing each element in an array with each other? `#each_combination`?

13:44 <jhass> yeah, that's probably as succint as you get it

13:45 <jhass> note there's an iterator returning overload, so you can chain .all? or whatever

13:57 <FromGitter> <Groogy> Hmm thinking more about it prob not what I want, thx anyway jhass

13:58 <FromGitter> <Groogy> the comparison I am trying to do is "obj at index X value needs to be less than the next one" and if I could put that in a oneliner that would be awesome

13:59 <jhass> basically that it's sorted?

13:59 <jhass> could check a.sort == a

14:00 <jhass> or .each_cons(2).all? {|a, b| a < b } or something like that

14:02 <FromGitter> <Groogy> think second one would be more efficent

14:03 <FromGitter> <oprypin:matrix.org> @Groogy: dont forget to apply `reuse: true`

14:03 <FromGitter> <Groogy> ah true thx

14:03 <FromGitter> <Groogy> each_cons_pair would be more optimized right?

14:04 <FromGitter> <oprypin:matrix.org> @Groogy: yes but it has no iterator version

14:04 <FromGitter> <Groogy> ah

14:05 <FromGitter> <Groogy> `invariant @control_points.each_cons(2, true).all? { |a,b| a.end_time < b.start_time }`

14:05 <FromGitter> <oprypin:matrix.org> does that actually work? it might need to be `|(a,b)|`

14:05 <FromGitter> <Groogy> Haven't used the Iterator much so should probably experiment with it bit more

14:06 <FromGitter> <oprypin:matrix.org> there are also these variants which would be more efficient

14:06 <FromGitter> <oprypin:matrix.org> https://carc.in/#/r/aubq

14:06 <FromGitter> <Groogy> yeah you're right

14:06 <FromGitter> <oprypin:matrix.org> https://carc.in/#/r/aubr

14:07 <jhass> they asked for a one-liner though :P

14:08 <FromGitter> <Groogy> yeah but hoped the oneliner would be readable so reconsidering that a bit right now

14:09 <FromGitter> <Groogy> `invariant @control_points.each_cons(2, true).all? { |(a,b)| a.end_time < b.start_time }` ⏎ versus ⏎ `invariant control_points_in_order?` ⏎ better name pending [https://gitter.im/crystal-lang/crystal?at=6073031806e2e024e84819aa]

14:13 <FromGitter> <Groogy> thanks for the help!

15:00 <FromGitter> <Daniel-Worrall> You should use `.each.cons_pair`

15:00 <FromGitter> <Daniel-Worrall> It's the iterator version

15:00 <FromGitter> <Daniel-Worrall> And it's optimised for being 2 elements

15:12 <FromGitter> <oprypin:matrix.org> oh nice. cc @Groogy

15:30 <FromGitter> <Groogy> oh cool thx

15:34 <FromGitter> <Groogy> Works perfectly yeah

15:36 <FromGitter> <Groogy> But think I am okay with not having the invariant be a oneline like I asked at start but name a function to describe the expected behaviour better: https://gist.github.com/Groogy/4f60b620407a072675d20d4b4da291c1

20:02 <FromGitter> <elementio:salt-rock-lamp.ems.host> Has anyone here had a dependency resolution issue with building Scry? I posted an issue on GH: https://github.com/crystal-lang-tools/scry/issues/185

20:02 <FromGitter> <elementio:salt-rock-lamp.ems.host> Am i missing some basic setup step?

20:02 <FromGitter> <Blacksmoke16> `--ignore-crystal-version` run it with that for now

20:03 <FromGitter> <Blacksmoke16> a new release needs tagged for 1.0.0 compatibility, see also https://github.com/crystal-lang/shards/pull/493

20:04 <FromGitter> <elementio:salt-rock-lamp.ems.host> I see, thank you

20:04 <FromGitter> <elementio:salt-rock-lamp.ems.host> I'm a bit surprised nobody else seemed to have this problem... are crystal devs generally in the habit of using that flag?

20:05 <FromGitter> <Blacksmoke16> probably, or just havent been using scry

21:23 <FromGitter> <asterite> I think crystalline is used more than scry, but I don't know

21:47 <FromGitter> <elementio:salt-rock-lamp.ems.host> i think scry was linked on the website while crystalline was not. is there a reason to prefer one over the other?

21:48 <FromGitter> <Blacksmoke16> afaik crystalline is more maintained

21:48 <FromGitter> <Blacksmoke16> on the website where?

21:48 <FromGitter> <elementio:salt-rock-lamp.ems.host> i thought maybe somewhere on the crystal site

21:48 <FromGitter> <elementio:salt-rock-lamp.ems.host> but i might be mistaken

21:48 <FromGitter> <Blacksmoke16> :shrug: is possible
