@oprypin good catch, thanks

@bew working on getting crystal-fann to support Float64 instead of Float32, the underlying C lib gives me trubles and I don't really know why :\
NeuraLegion/crystal-fann#6
so annoying :(
Ghost
@ghost~55586c4815522ed4b3e08557
Ah, no idea how I could help, I don't understand anything about what you'r doing! :joy:
Bar Hofesh
@bararchy
lol, it's just something stupid , I guess I need something to be a float ...
Is there a way to automagiclly cast Array(Float64) to Array(Float32) ?
Ghost
@ghost~55586c4815522ed4b3e08557
With a map?
You can't automagically do that
Plus, I think you need to save the generated array before sending it to the lib (to prevent it being collected by the gc while in us in the lib)
Bar Hofesh
@bararchy
Something I would really like in specs, it to have a
on_fail do 
  puts debug_info
end
this way I don't need to just print stuff out if I dont need it
only if specs fails
Rubi
@codenoid

btw,

puts "slay"
exit 0
at_exit { puts "bye" }

why at_exit should be above exit

Serdar Dogruyol - Sedo セド
@sdogruyol
you call exit before declaring at_exit
From IRC (bridge bot)
@FromIRC
<oprypin> @codenoid, at_exit is a method. in your example it's never called
Rubi
@codenoid
but, "I will do at_exit, when I exit " :/ :+1:
Serdar Dogruyol - Sedo セド
@sdogruyol
why not moving at_exit line up?
Rubi
@codenoid
I am just asking :shipit:
Bar Hofesh
@bararchy
@codenoid you can also
def foo
  bla
  bla
  exit
rescue SystemExit
  do stuff here
end
I wouldn't do that, but it's a posibilty
Ghost
@ghost~55586c4815522ed4b3e08557
Huh
Not in Crystal
Bar Hofesh
@bararchy
wouldn't work ?
From IRC (bridge bot)
@FromIRC
<oprypin> undefined constant SystemExit
Ghost
@ghost~55586c4815522ed4b3e08557
Exit doesn't raise an exception
Bar Hofesh
@bararchy
Oh..
Ghost
@ghost~55586c4815522ed4b3e08557
It simply exits!
Bar Hofesh
@bararchy

In Ruby this:

def test
  exit
rescue Exception => e
  puts e, e.class
end

test

Returns this:

exit
SystemExit
So I guess in this regard it's not comptabile
@codenoid Sorry for misleading
Rubi
@codenoid
no problem @bararchy , thanks for sharing :sparkles:

Is there a way to rescue compile time errors in order to provider more info to the user? I've found that in some of the libraries I'm writing the compile time errors would be a lot more helpful with a little more info. So instead of something like "must return LuckyWeb::Response not WhateverType" it could say that and "that usually means you need to call render or redirect at the end of your action"
From IRC (bridge bot)
@FromIRC
<oprypin> @paulcsmith, no u cant rescue, but maybe u can anticipate those cases and make them nonfatal but with a manual {% raise "" %} in them
<oprypin> needs an example to say more
<oprypin> if return_result.is_a? LuckyWeb::Response; good stuff; else; {% raise
