15:52 <pawnbox> How to create hash with key string and value hash?

15:52 Ven has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]

15:52 <pawnbox> This obviously didn't work.

15:52 <pawnbox> > env = {} of String => {} of String => String

15:54 <pawnbox> >> env = {} of String => {} of String => String

15:54 <DeBot> pawnbox: Syntax error in eval:21: expecting token 'CONST', not '}' - http://carc.in/#/r/k9d

15:54 <jhass> >> {} of String => String => String

15:54 <DeBot> jhass: Syntax error in eval:21: unexpected token: => - http://carc.in/#/r/k9e

15:54 <jhass> worth a shot

15:55 <jhass> >> {} of String => (String => String)

15:55 <DeBot> jhass: Syntax error in eval:21: expecting token ')', not '=>' - http://carc.in/#/r/k9f

15:55 <jhass> >> {} of String => Hash(String, String)

15:55 <DeBot> jhass: # => {} - http://carc.in/#/r/k9g

15:55 <jhass> pawnbox: ^

15:55 <pawnbox> Aha

15:56 <pawnbox> jhass: isn't Hash(String, String) same as {} of String => String

15:56 <pawnbox> ?

16:04 <jhass> pawnbox: no, Hash(String, String).new is the same as {} of String => String

17:12 <RX14> ok, when I last checked, if you tried to use IO in a system thread, you got a segfault... that still happens right?

17:15 <jhass> should

17:15 <jhass> well, last time I checked I got some exception

17:19 <RX14> then, we are still far away from fibers beeng on multiple cores :C

23:49 Tetsumi has joined #crystal-lang

23:50 nakilon has joined #crystal-lang

23:51 <Tetsumi> How can i build a string from an array of Char ?

23:51 <jhass> Tetsumi: Crystal array or C array?

23:52 <Tetsumi> crystal array: [] of Char

23:52 <jhass> >> ['a', 'b', 'c'].join

23:52 <DeBot> jhass: # => "abc" - http://carc.in/#/r/kao

23:53 <Tetsumi> thanks

23:56 <Tetsumi> wouldn't be more intuitive if String had a constructor for Array(Char) so one could do String(['a', 'b', 'c']) ?

23:57 <jhass> that would be calling the method String

23:57 <jhass> but I wouldn't say so, join works for any kind of array

23:58 <jhass> it simply calls to_s on the elements, which is defined for all objects
