@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"

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

Is there such a thing as a private macro?

@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

Llvm is too big: 3 GB
Why did I add --with-llvm option
I am so pişman :(

Finally I have built it in 14 min 12 sec

@sdogruyol
you have some low specs?
Ekrem Karaca
@ekremkaraca
I wonder what llvm source contains?
Yep
Serdar Dogruyol - Sedo セド
@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?
<Groogy> doesn't it show there?
<femto> Syntax error in expanded macro: macro_4594465744:1: can't define def inside def [def foo ^ ================================================================================ {{@type.methods}} # using all_subclasses for illustration
<femto> in src/hello2.cr:11: macro didn't expand to a valid program, it expanded to: ================================================================================ -------------------------------------------------------------------------------- 1. [def foo 2. end]
From IRC (bridge bot)
@FromIRC
<Groogy> you probably have to do something more sensible than {{@type.methods}} since that probably just expands into the methods own defintion it seems
<Groogy> methods is a collection of ASTNodes is my guess you probably have to create a macro that converts them to like an array of strings
<Groogy> or similar
