05:55 <FromGitter> <CyberneticSquid> Trying to use this shard https://github.com/szTheory/zaru_crystal and getting a weird issue when doing `shards install` ⏎ ⏎ ```code paste, see link``` ⏎ ⏎ Not sure what's causing it since that doesn't match the actual shard.yml [https://gitter.im/crystal-lang/crystal?at=6188bbeefb3dcd4e8873e045]

07:19 <postmodern> how do you test non-abstract methods defined in an abstract class? sub-class it in the specs?

07:21 <postmodern> also if you have a #each(&block : (...) ->) method and a #each() : Iterator method, how do you call the non-block-taking version of #each from the version of #each that accepts a block?

07:45 <postmodern> hmm also why isn't `&block : () -> ...` valid syntax?

07:45 <postmodern> i feel like `() ->` is more explicit than just ` -> `

14:26 <FromGitter> <Blacksmoke16> > *<postmodern>* how do you test non-abstract methods defined in an abstract class? sub-class it in the specs? ⏎ ⏎ Yea, id define a mock implementation of it in the specs that could be used

17:12 <FromGitter> <HertzDevil> `Indexable.each_cartesian`

21:58 <FromGitter> <postmodern:matrix.org> @HertzDevil: what if the data isn't Indexable, but just a free form Iterator without a defined length?

22:43 <FromGitter> <domgetter> Are there any shards for SIMD stuff like a nice wrapper around AVX2 ?

22:45 <FromGitter> <domgetter> I'm doing some custom per-pixel filters on images, and was hoping to be able to unroll the inner loop and work on 8 pixels at a time

22:47 <FromGitter> <domgetter> (or, more precisely 8 channels at a time)

22:51 <FromGitter> <christopherzimmerman> If you haven’t seen it, some work was started: https://github.com/malte-v/crystal/tree/simd-support
