<oprypin> LIBRARY_PATH is for build LD_LIBRARY_PATH is for execution. so have u tried both?

I just see it :sweat_smile:

Does Crystal have something like Intersection Types ? [0]

@faustinoaq I don't get it, what's the difference with our unions?
Faustino Aguilar
@faustinoaq

I'm a bit confused, because I think unions behave differently [0]

[0] - https://flow.org/en/docs/types/unions/

Maybe it's not valid to compare Flow & Crystal :sweat_smile:

Ghost
@ghost~55586c4815522ed4b3e08557
From the given examples, I don't think intersection type is relevant in Crystal

@ezrast
You might want to require that an object's class includes two different modules

@ghost~55586c4815522ed4b3e08557
oh right
ezrast
@ezrast
I don't know what a real use case would look like though
Ghost
@ghost~55586c4815522ed4b3e08557
no idea too

<oprypin> @faustinoaq, what's your use case?
Martin Verzilli
@mverzilli
when you're augmenting JS with Flow it makes sense because then you can annotate a param as "whatever you send here should have an attribute X and an attribute Y"
Ghost
@ghost~55586c4815522ed4b3e08557
pinging @asterite will maybe bring a little light here
yes @mverzilli that's what I was thinking too
Martin Verzilli
@mverzilli
in JS it's common to use ad-hoc objects to sort of gimmick named arguments, for example
Flow is a huge attempt at reverse engineering common patterns of use in JS and type-check them
well "reverse engineering" is a very poor choice of terminology :P, it'd be more "capturing"

can someone help explain the usage of fun outside of a lib declaration to me?
I've seen it used in some issues as a way to mess with the definition of main
but I don't fully understand how that works

@elorest
Is there such a thing as a private macro?
Faustino Aguilar
@faustinoaq

<oprypin> what's your use case?

None, I was reading flow documentation, and then I ask me if there is something similar on Crystal, but the @mverzilli answer solved my question. :+1:

can someone help explain the usage of fun outside of a lib declaration to me?

I think the fun usage outside libs is very limited, fun doesn't support overloading and only support basic types, I think it is more like a C function, thinking on shared libraries or similar stuff.

@bew Sorry for the late reply. Yes I saw your wiki - pretty good. I didn't do so much research. I knew that I wanted to parse PEGs, and I liked the DSL of Parslet. I looked at D's Pegged, Clojure's Instaparse, Haskell's Earley and a couple from Go. Although I didn't spend much time ruminating and went to implementation.

<oprypin> @elorest, you can put a macro in a private module

Morning πŸŒ„πŸ‘‹
I am now trying to install Crystal via Linuxbrew
I think we should include it to the book

@sdogruyol
you have some low specs?

@ekremkaraca
I wonder what llvm source contains?
Yep

@sdogruyol
LLVM is a beast, lots of C++

<Groogy> Morning!
<femto> class Hierarchy def foo end def self.methods {{@type.methods}} # using all_subclasses for illustration end end class A < Hierarchy; end class B < A; end class C < B; end puts Hierarchy.methods
<femto> how do I get all the methods of a class?
