01:18 <FromGitter> <3n-k1> This code works without the module part, but with the module part I get "Error: undefined method 'index_view' for Cwiki:Module". What am I doing wrong? ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=5e8148f4ceb7644818445adc]

01:28 <FromGitter> <Blacksmoke16> It's probably a class method

01:28 <FromGitter> <Blacksmoke16> Try ->Cwiki.index_view

01:29 <FromGitter> <3n-k1> same error

08:49 <FromGitter> <straight-shoota> @3n-k1 `index_view` is a class method, you can't call it on the module. Define it as `def self.index_view` to be able to call `Ciwiki.index_view`.

11:24 <FromGitter> <ImAHopelessDev_gitlab> hi

11:38 <FromGitter> <jordifreek> Hello

11:38 <FromGitter> <jordifreek> What is the best way to share data between a fiber and the main scope?

11:39 <FromGitter> <jordifreek> On this code, i can't access the array `clients` inside the fibber `handle_client` ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=5e81da6447c92241cfb53d23]

11:40 <FromGitter> <jordifreek> Can i pass the `clients` array to the `handle_client` method? what if the clients has a large amount of data, should it explode with the 8mb of a fiber? Also, is `clients` passed by reference?

11:55 <yxhuvud> jordifreek: the best way is usually to use a Channel.

12:01 <FromGitter> <jordifreek> thanks @yxhuvud, all the info is inside concurrency section of hte Reference Guide?

12:01 <yxhuvud> I don't know. You may have to check the api docs as well

12:02 <FromGitter> <jordifreek> thanks
