@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.

@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]

@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

@sdogruyol morning! - finally got around to adding this to github - https://github.com/crisward/mailer

femto, use @type.methods.map &.name.stringify

What is this type syntax *{Int32, Int32} (from https://github.com/crystal-lang/crystal/issues/5037#issuecomment-332381702)
Should it mean something specific in his example?
Serdar Dogruyol - Sedo セド
@sdogruyol
deconstructing the tuple?
(haven't looked at the issue)
Ghost
@ghost~55586c4815522ed4b3e08557
Look at it please (or below)
It's used in def bla(*arg : *{Int32, Int32})
From IRC (bridge bot)
@FromIRC
<oprypin> @bew, it's invalid syntax, hence the error
<oprypin> except that the compiler should say invalid syntax not break
Ghost
@ghost~55586c4815522ed4b3e08557
Okay, makes sense
