I think we should include it to the book
Why did I add --with-llvm option
I am so pişman :(
Yep
that explains
<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
<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
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?
(haven't looked at the issue)
It's used in
def bla(*arg : *{Int32, Int32})
<oprypin> except that the compiler should say invalid syntax not break
<oprypin> @bew, nevermind lol https://github.com/crystal-lang/crystal/blob/8a00ab47e58ac23835c8fd60e1aed4ad19a9aaf9/src/tuple.cr#L80
