Can you test on non-arm?

From IRC (bridge bot)

@FromIRC

<mps> I can, but maybe next week (ditched x86 few years ago)

<mps> hmm, maybe I can 'usurp' my alpine developers lxc

<mps> but not now, it is to busy by building a lot of pkgs now

didactic-drunk

@didactic-drunk

Nm. It's possible it needs crystal master although I don't see why. I hope it's not an arm thing

@FromIRC

<mps> last time I tried it was same on arm and x86

<postmodern> is there a way to create an tuple of arbitrary length, but all elements are of the same type?

George Dietrich

@Blacksmoke16

No tuples are fixed suze by design

Size

Chris Watson

@watzon

Is there a good thread safe queue yet?

Or am I going to have to implement one quickly?

George Dietrich

@Blacksmoke16

Rabbit?

Chris Watson

@watzon

Rabbit would probably be a good idea actually, but this is a smaller project and I'd rather avoid external deps like that if I can. I really just need a deque that is thread safe.

George Dietrich

@Blacksmoke16

That's fair

There's one in the stdlib, but idk if it's thread safe or not

Chris Watson

@watzon

Yeah iirc it isn't

From IRC (bridge bot)

@FromIRC

<yxhuvud> @watzon: can you use a channel?

Quinton Miller

@HertzDevil

is there a design reason that x.as?(T) isn't equivalent to x if x.is_a?(T)

(the difference is that the former returns a T? and the latter returns a (typeof(x) & T)?)

From IRC (bridge bot)

@FromIRC

<yxhuvud> subclasses?

Quinton Miller

@HertzDevil

why do you think so

From IRC (bridge bot)

@FromIRC

<yxhuvud> no good reason.

From IRC (bridge bot)

@FromIRC

<yxhuvud> looking at the documentation for as, I guess the upcast possibility to union type could be responsible?

From IRC (bridge bot)

@FromIRC

<yxhuvud> ie it allows you to do things like [1.as?(Int32|String)] << "hello" which is not possible using 1 if 1.is_a?(Int32|String) instead

Quinton Miller

@HertzDevil

oh yeah upcasts

what about x.as?(T) versus x.as(T) if x.is_a?(T)

Lance Dillon

@riffraff169

as a not quite rabbit expert, running rabbit in a container is very simple, so not much required to use it...it would be simple to use for your app

Lance Dillon

@riffraff169

could even have a script that starts the rabbit container, runs your app, then when app quits, rabbit quits

<postmodern> what is IO::ARGF ?

From IRC (bridge bot)

@FromIRC

<postmodern> ah ha. hmm now to figure out why it's showing up in my specs when i am clearly calling IO::Memory#gets

George Dietrich

@Blacksmoke16

my site has gotten even better. now features a shared video player in rooms (+ video/audio calls + collaborative text editor + collaborative painting + html chat)

crystal + amber + websockets + mediaelement.js

@FromIRC

<kevinsjoberg> Do we have some guidelines for the Crystal tooling repositories? I've been contributing to the Crystal TextMate bundle fairly frequently and just noticed I have merge rights (I'm part of Crystal Tooling). I just submitted a PR but not sure who would be suitable for review. Would people be okay with me just merging the fix?

<kevinsjoberg> See crystal-lang-tools/Crystal.tmbundle#22 for details.

George Dietrich

@Blacksmoke16

for simple stuff like this id prob just merge it

From IRC (bridge bot)

@FromIRC

<kevinsjoberg> @Blacksmoke16, alright. Sweet. 🙂

George Dietrich

@Blacksmoke16

it looks good to me fwiw ;P

hello, Im on crystal 1.0.0, running basic logger output,

require "logger"

log = Logger.new(STDOUT)
log.level = Logger::WARN

log.debug("Created logger")
log.info("Program started")
log.warn("Nothing to do!")

getting

require "logger"
^
Error: can't find file 'logger'

running on linux mint 20.1

George Dietrich

@Blacksmoke16

It's require log

Logger was the old version

@perfecto25

thx, was looking at old docs

George Dietrich

@Blacksmoke16

https://crystal-lang.org/api/Log.html is the one you want to use now. One you're using atm is the legacy one
