02:50 <FromGitter> <girng> @j8r yep. i will be forever

04:47 <FromGitter> <proyb6> Looking at Golang and someone shared a link in Reddit https://www.ageofascent.com/2019/02/04/asp-net-core-saturating-10gbe-at-7-million-requests-per-second/

04:48 <FromGitter> <proyb6> How nice if Crystal could do zero allocation on Plaintext

05:47 <FromGitter> <girng> how can i convert a long byte list to its original image data? a list of bytes like this (https://i.gyazo.com/dfb77c7c726a2b94cc14f060df9decd9.png). i'm getting the data from the tcp stream with godot's put_data (https://github.com/godotengine/godot/blob/b16c309f82c77d606472c3c721a1857e323a09e7/core/io/stream_peer.cpp#L435). i'm trying to send the image data from a client's computer across the tcp stream and for

05:47 <FromGitter> ... crystal to get the bytes and save it as a image (png, jpg, jpeg). basically uploading an image and for crystal to save the file when it has all the bytes. i'm at the point where crystal has all the bytes (socket.peek) displays them. but i need to convert these bytes to an image. that i don't know how to do. ⏎ ⏎ for exam ... [https://gitter.im/crystal-lang/crystal?at=5c59235cc2dba5382ee20ae3]

05:48 <FromGitter> <girng> this is what it should be: https://i.gyazo.com/43e2289fa6450dd515dd9ea067b6f8f7.png

06:26 <FromGitter> <kingsleyh> I can’t read all the code in gitter as it gets cut off - but did you try socket.read_fully

06:27 <FromGitter> <kingsleyh> Then String.new(the_bytes)

06:28 <FromGitter> <kingsleyh> @girng

06:28 <FromGitter> <girng> kk trying now

06:42 <FromGitter> <girng> OMG LMAO

06:44 <FromGitter> <girng> @kingsleyh that was the biggest fail I think i ever did in my entire life. i was using the `get_data()` from https://docs.godotengine.org/uk/latest/classes/class_image.html which returns *Returns the image’s raw data.*. This is not the same as the CONTENTS of the image *file* itself.

06:46 <FromGitter> <girng> so i did `file.get_buffer(file.get_len())` instead of the `get_data()` on the image texture, and boom: uploaded it through crystal's stream PERFECTLY

06:49 <FromGitter> <girng> Gosh i love crystal makes it so freaking easy. was having so many problems with godot's dumb http client crap

06:50 <FromGitter> <girng> so instead of an http request, i just piped those bytes through a tcp stream LOL 😆

06:55 <FromGitter> <kingsleyh> Nice!

06:59 <FromGitter> <kingsleyh> Hmm from the docs it does look like it should contain the image data as bytes in a PoolByteArray - so if it’s not enough to materialise the image then that’s very misleading!

07:05 <FromGitter> <girng> yeah, it's weird, def different data lol

08:13 <FromGitter> <girng> lol @ my google results (https://i.gyazo.com/182ad3496915b1e13b39629acfc265cb.png)

08:17 <FromGitter> <girng> anything like this in the shards? http://php.net/manual/en/function.getimagesize.php

08:18 <FromGitter> <girng> really just need to get the width or height of a jpg or png

10:30 <mps> j8r: you wanted that: community/libzip: build static libzip.a and add it to -dev apk

10:30 <FromGitter> <j8r> yes mps :)

10:31 <mps> it is pushed right now

10:31 <FromGitter> <j8r> Awesome, thanks a lot mps. Yesterday I've succeeded to run Nextcloud with my statically-linked php :)

10:33 <mps> 11:25 ........ algitbot| aports:master |xxxxx x. xxxxxx| community/libzip: build static libzip.a and add it to -dev apk | http://dup.pw/aports/4d1093eb

10:36 <mps> j8r: you are welcome, we all trying to help each other. you help me explaining some things/intricacies about crystal

10:53 <FromGitter> <j8r> exactly mps, 👍

11:50 <FromGitter> <vivus-ignis> hi! ⏎ is there a way to define a type which covers a class and all of its subclasses? ⏎ that is, to fix a compilation error like this one: ⏎ ⏎ `instance variable '@installed' of PackageManager must be Array(Package), not Array(Package::Deb)` ... [https://gitter.im/crystal-lang/crystal?at=5c59789cc2dba5382ee42b6a]

12:12 <FromGitter> <j8r> have you an example @vivus-ignis ?

12:13 <FromGitter> <j8r> if you do `Array(Package | Package::Deb)`?

12:13 <FromGitter> <j8r> or you can have `alias Packages = Package::Deb | Package::RPM` for example

12:24 <FromGitter> <vivus-ignis> @j8r it is something like this ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=5c5980908aa5ca5abf8a1161]

12:25 <FromGitter> <vivus-ignis> i would have to edit an alias for each new subclass

12:26 <FromGitter> <j8r> Have you tried with generics?

12:26 <FromGitter> <vivus-ignis> no

12:27 <FromGitter> <vivus-ignis> let me see...

12:27 <FromGitter> <j8r> you can also use generics with composition, like `include PackageManage(Deb)`

12:28 <FromGitter> <j8r> With inheritance there are feedbacks that suggests the implementation is a bit buggy

13:34 <FromGitter> <kingsleyh> What is the type you use when you want to specify a Float but want it to work with both Float32 and Float64

13:34 <FromGitter> <kingsleyh> Is it something like float_t

14:08 <FromGitter> <bew> you can try `Float` for a type restriction, but it won't work for an ivar.. otherwise you can always do `Float32 | Float64`

15:21 <FromGitter> <j8r> @PlayLights_twitter you give me the idea to implement an `Object#send` library, based on macros

15:23 <FromGitter> <j8r> WIP: https://play.crystal-lang.org/#/r/66b0

15:25 <FromGitter> <Blacksmoke16> neat

15:25 <FromGitter> <bew> Meh

15:26 <FromGitter> <j8r> perhaps this can be considered as a bad practise to use this

15:26 <FromGitter> <j8r> but the challenge is here :)

15:27 <FromGitter> <j8r> it could be used in interpreters too

15:30 <FromGitter> <Blacksmoke16> was looking at adding a `to_xml` to CrSerializer

15:30 <FromGitter> <Blacksmoke16> be a bit tricky on how to handle like arrays of ints

15:31 <FromGitter> <Blacksmoke16> have to see if there is some spec around it

16:27 <FromGitter> <chussenot> Hi guys, is there any mature initiative to build a lib to interact with docker API?

16:34 <FromGitter> <Sija> @chussenot I’m not sure how mature you’d call it, but there’s https://github.com/jeromegn/docker.cr

17:06 <FromGitter> <chussenot> This project is too old and can't be compiled with last versions of crystal... and he manage few things

17:06 <FromGitter> <chussenot> ;)

17:13 <FromGitter> <bew> @chussenot I guess you'll have to make your own.. (btw tu connais https://www.meetup.com/fr-FR/pariscrystal/ ?)

17:29 <FromGitter> <fridgerator> 1) 27.2 already 0.o

17:29 <FromGitter> <kevinelliott> woot!

17:29 <FromGitter> <fridgerator> looks like 0.27.1 had some regressions?

19:24 <mps> 0.27.2 on Alpine builds with llvm6 but fails on test. here is the error message: http://tpaste.us/7vDO
