<gcds> now I got it :⁠D

@FromIRC

<gcds> hmm it did not worked like I expected trying something out :⁠(

<gcds> I am feeling bit like idiot... the original PKCS5_PBKDF2_HMAC_SHA1 is found but additional PKCS5_PBKDF2_HMAC method is not found then its in the same lib. Even then in OpenSSL PKCS5_PBKDF2_HMAC_SHA1 wraps a call PKCS5_PBKDF2_HMAC

<gcds> Ok i reproduced the error again and fixed with simple flag. https://gist.github.com/aurimasniekis/422e6dfaf3b256d1d9bcea40ae54ef72

<gcds> but the same thing does not work on CircleCI :⁠(

Why I am getting method addme undefined error?

module Helpers

def addme(x : Int32, y : Int32)
return x+y
end

puts addme 3,4

end

George

@georgeu2000

What are you trying to do? Define a class?

Nick Franken

@fridgerator

module Helpers
  def self.addme(x, y)
    return x + y
  end

  self.addme(1, 2)
end

or extend self inside the module

How to define a Hash( Int32, Int32 ) with an initial value of 0 for each key?

Rinkana

@Rinkana

You dont

George

@georgeu2000

Tried Hash.new( Int32, Int32 ){ 0 } but it did not work.
Seems like you can according to https://github.com/crystal-lang/crystal/blob/e2a1389e8165fb097c785524337d7bb7b550a086/src/hash.cr#L28

Rinkana

@Rinkana

Hash keys are unique so there can be one 0

George

@georgeu2000

Oops. I meant value.

@georgeu2000 Hash(Int32, Int32).new(default_value: 0) I guess?

George

@georgeu2000

It worked. Thanks!

the rusters started to rewrite the libc in pure rust. That's impressive

@jwaldrip

Can you use macros to construct case statements?

Seems like I get an error when trying to do so

Ghost

@ghost~55586c4815522ed4b3e08557

make sure to enclose it with {% begin %} ... {% end %} as explained here https://crystal-lang.org/docs/syntax_and_semantics/macros.html#pitfalls

@krypton97 that's some big effort :)

Jason Waldrip

@jwaldrip

with self yield does not seem to be working

Ghost

@ghost~55586c4815522ed4b3e08557

can you be a bit more precise?

Jason Waldrip

@jwaldrip

hold on, putting together an example

actually, just self does not work

in the block

nvm :-)

@unreadable

Well, it's unix based and a good part of the code is copy pasted . I guess not so many devs wanna mess with win api

Serdar Dogruyol - Sedo セド

@sdogruyol

It's not that but more likely there arent much devs who knows much about win32 stuff @krypton97

unreadable

@unreadable

Ikr. There's also musl which seems to do better than the gnu implementation https://www.musl-libc.org/

unix based again :)
