07:07 <FromGitter> <oprypin:matrix.org> @naqvis: btw you gain nothing from using a specific version number rather than just v1

07:10 <FromGitter> <naqvis> you mean `install-crystal` version?

07:11 <FromGitter> <naqvis> I had switched to version as there was problem with OSX https://github.com/oprypin/install-crystal/issues/3

07:12 <FromGitter> <oprypin:matrix.org> yes. v1 covers v1.* and auto-updates

07:12 <FromGitter> <naqvis> gotcha

07:13 <FromGitter> <naqvis> so replacing specific version with v1 gonna fix this?

07:13 <FromGitter> <oprypin:matrix.org> and i don't expect to break stuff within those updates :>

07:13 <FromGitter> <naqvis> 👍

07:13 <FromGitter> <oprypin:matrix.org> @naqvis: yes v1 or v1.4.0

07:13 <FromGitter> <naqvis> ❤️

07:13 <FromGitter> <naqvis> let me try that

07:17 <FromGitter> <naqvis> that works. Thanks @oprypin:matrix.org

07:45 <FromGitter> <tkshnwesper> Hi all

07:45 <FromGitter> <naqvis> \o

07:45 <FromGitter> <tkshnwesper> My travis builds have started failing (https://travis-ci.com/github/tkshnwesper/agyan/builds/225295620)

07:46 <FromGitter> <tkshnwesper> Has ubuntu removed the crystal package?

07:57 <FromGitter> <naqvis> i assume so, Travis-CI wasn't officially supported even before. You should be migrating to GitHub Actions

07:59 <FromGitter> <tkshnwesper> Ok, will do. But the travis config file is part of the `crystal init` template (https://github.com/crystal-lang/crystal/blob/421fa11bf05b11441b74bbeb2762b673f96fec3f/src/compiler/crystal/tools/init/template/travis.yml.ecr). It would fail for everyone else too

08:00 <FromGitter> <naqvis> true, you can raise an issue to have that removed

08:01 <FromGitter> <tkshnwesper> ok 👍

11:43 <FromGitter> <Daniel-Worrall> Theres already an issue tracking the init and CI config

11:43 <FromGitter> <Daniel-Worrall> I'd leave a comment in there about it

13:19 <FromGitter> <naqvis> Just published a Unicode Char and String Width shard https://github.com/naqvis/uni_char_width

13:20 <FromGitter> <naqvis> @Blacksmoke16 don't know if it will be of any use to your CLI development

14:06 postmodern has quit [Quit: Leaving]

14:10 <FromGitter> <Blacksmoke16> oh snap, nice one!

14:11 <FromGitter> <naqvis> ❤️

14:11 <FromGitter> <Blacksmoke16> totally should add that stuff to the unicode data file and stdlib ❤️ looks super useful

14:13 vasanth has joined #crystal-lang

14:19 <FromGitter> <Blacksmoke16> https://github.com/naqvis/uni_char_width/blob/main/spec/char_width_spec.cr#L37-L38 ⏎ ⏎ FWIW i think you can do like `wid.should eq(tc[1]), "Char width(#{tc.first}) = #{wid}, want #{tc[1]} (east_asian = false)"` now.

14:20 <FromGitter> <naqvis> 👍 Thanks

14:21 <FromGitter> <Blacksmoke16> prob not worth changing, but for future use :)

14:21 <FromGitter> <naqvis> yeah, wasn't aware of this idiom

14:21 <FromGitter> <naqvis> thank you

14:21 <FromGitter> <Blacksmoke16> https://github.com/crystal-lang/crystal/pull/10127

14:23 <FromGitter> <naqvis> definitely helpful

14:24 <FromGitter> <naqvis> TIL this new feature. Thank you again ❤️

14:24 <FromGitter> <Blacksmoke16> np, maybe you'd be interested in https://athenaframework.org/Spec/TestCase/DataProvider/ 😉

14:25 <FromGitter> <naqvis> let me go through the docs

14:27 <FromGitter> <Blacksmoke16> essentially is just a syntactical sugar on `Spec` module. i.e. adds an `it` block for each item that'll be provided

14:27 <FromGitter> <naqvis> WoW

14:27 <FromGitter> <naqvis> so framework will invoke the method for all data inside the `Provider` ?

14:30 <FromGitter> <Blacksmoke16> ```code paste, see link``` ⏎ ⏎ expands to this. I.e. normal `Spec` code [https://gitter.im/crystal-lang/crystal?at=6096a071d964ec553898e11b]

14:30 <FromGitter> <oprypin:matrix.org> oh god the flashbacks to golang ⏎ https://github.com/naqvis/uni_char_width/blob/38cec8af74c0b3a63042528e63afc64600c8e307/spec/char_width_spec.cr#L36

14:30 <FromGitter> <Blacksmoke16> where all the code happens in a `.run` method that's like `instance = new`

14:32 <FromGitter> <naqvis> @oprypin:matrix.org 😺

15:22 <FromGitter> <naqvis> @Blacksmoke16 move to `Athena::Spec` was quite smooth 👍

15:23 <FromGitter> <naqvis> Love that `Provider` stuff

15:23 <FromGitter> <Blacksmoke16> ❤️ pretty cool eh?

15:24 <FromGitter> <naqvis> yeah, beautiful 👍

15:24 yxhuvud has joined #crystal-lang

15:24 <FromGitter> <Blacksmoke16> i really like having a type to use when writing specs for non trivial things

15:24 <FromGitter> <naqvis> yeah, same is here

15:24 <FromGitter> <Blacksmoke16> otherwise there just isnt really a good way to share helpers/tests between common types

15:25 <FromGitter> <naqvis> the best thing I love is, it count each iteration as a separate run

15:25 <FromGitter> <naqvis> as previously I was iterating through the array inside a single TC

15:25 <FromGitter> <naqvis> so in console it was just a one TC

15:26 <FromGitter> <naqvis> though not a big deal, but why can't I mark those provider methods as private?

15:26 <FromGitter> <naqvis> i know this is Crystal limitation

15:26 <FromGitter> <Blacksmoke16> protected should do

15:26 <FromGitter> <Blacksmoke16> maybe

15:26 <FromGitter> <naqvis> yeah, that's how I circumvent this

15:27 <FromGitter> <Blacksmoke16> ☝️ May 8, 2021 10:30 AM (https://gitter.im/crystal-lang/crystal?at=6096a071d964ec553898e11b)

15:27 <FromGitter> <naqvis> but shouldn't the same scope things has access to scoped value

15:27 <FromGitter> <Blacksmoke16> because this is just syntactical sugar, it essentially does `instance.provider_name` so has to be visible

15:28 <FromGitter> <naqvis> yeah, i was talking about compiler limitation

15:28 <FromGitter> <Blacksmoke16> i mean is it a compiler limitation? this isnt any diff than like ⏎ ⏎ ```instance = new ⏎ instance.private_method``` ⏎ ⏎ which ofc that wuldnt work [https://gitter.im/crystal-lang/crystal?at=6096ae320845c416dccfe26a]

15:31 <FromGitter> <naqvis> yeah, but thing is it doesn't even allow the scoped access

15:32 <FromGitter> <naqvis> actually as long as you add Namespace name infront of private methods, compiler start screaming

15:33 <FromGitter> <naqvis> This will work ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=6096af3bd5e2793379fcf3c7]

15:34 <FromGitter> <Blacksmoke16> ahh yea, private method invocations cant have a receiver other than `self`

15:34 <FromGitter> <Blacksmoke16> :shrug:

15:35 <FromGitter> <Blacksmoke16> private and protected in crystal arent like private and protected in other langs like PHP

15:35 <FromGitter> <Blacksmoke16> took a bit of getting used to

15:35 <FromGitter> <straight-shoota> it's like Ruby =)

15:35 <FromGitter> <Blacksmoke16> coming from a more PHP background it was diff

15:36 <FromGitter> <straight-shoota> deffinitely

15:36 <FromGitter> <straight-shoota> some background on private self https://github.com/crystal-lang/crystal/issues/5995

15:41 <FromGitter> <naqvis> Thanks @straight-shoota , last comment in that thread is :P ⏎ ⏎ > I guess we can do the same then.

15:41 <FromGitter> <naqvis> but issue is already closed, shouldn't it be opened again? :P

15:58 <straight-shoota> But this was already merged before in #6075

15:58 <DeBot> https://github.com/crystal-lang/crystal/pull/6075 (Allow private method invocation with self receiver)

20:45 <FromGitter> <Blacksmoke16> was able to get it to work via `NONE = 0`
