04:41 <epitron> slop!

04:42 <epitron> does crystal not have a datastructure that can store mixed types?

09:20 <jhass> epitron: mixed types (aka unions), yes. Arbitrary types (=unknown which will end up in it until runtime), no

13:40 <asterite> epitron: we talked many times about letting you use Object or Reference for "Any". For example, a = [] of Object; a << 1; a << "hello"; But then to use each object you always have to cast it, so it would be like a void* in C

16:41 <epitron> hmmm

16:42 <epitron> asterite: I see... well, in the option parser DSLs, you usually specify the type..

16:43 <asterite> Yes, but if you store it in a hash then when you get the value out of it you must specify the type again

16:43 <epitron> okay... so it has to generate an object to store the values I guess

16:46 <asterite> I think that in that case you can have a Hash(String, Int32 | Float64 | String | Bool) for example, no need to use Object, but you'd have to cast the type afterwards. But it can be done like opt.int("flag")

16:47 <asterite> In any case, I think OptionParser is more flexible: you get the passed value and you can do whatever you want with it. Want an int? Invoke .to_i. It's not that much code :)

20:56 <epitron> a nice simple DSL for parsing args would be great though

20:56 <epitron> opts, args = ARGV.parse { opt "--stuff", "-s", "Do stuff!" }

20:57 <epitron> all those opt flags could generate a typed object, right?

21:41 <crystal-gh> [crystal] asterite pushed 4 new commits to master: http://git.io/jnDT

21:41 <crystal-gh> crystal/master 623df25 Ary Borenszweig: Improved File.join performance, and fixed its semantic (don't remove more than one slash)

21:41 <crystal-gh> crystal/master ef98a46 Ary Borenszweig: Use File::SEPARATOR in more places

21:41 <crystal-gh> crystal/master 9b97034 Ary Borenszweig: Continued XML
