<gcds> Maybe someone could help me. I am trying to compile std lib and get problem I think on mac somehow std lib cant find libcrypto. Maybe someone has encountered this problem? pkg-config libcrypto doesnt return nothing...
<gcds> it does return sorry but still I cant build :⁠(
<gcds> i think I know the problem my openssl is to old

Hey all, I'm trying to make crystal app with Kemal, Granite ORM on postgres. My question is I created one model that needs to update password to encrypted one. But on the build, It's giving error as...

instance variable '@password' of User must be (String | Nil), not Crypto::Bcrypt::Password

require "granite_orm/adapter/pg"
require "crypto/bcrypt/password"
require "logger"
require "kemal"

log = Logger.new(STDOUT)
log.level = Logger::WARN

class User < Granite::ORM::Base
  adapter pg

  before_save :prepare_data

  field email : String
  field password : String
  timestamps

  def prepare_data
    if password = @password
      log("#{password}")
      @password = Crypto::Bcrypt::Password.create(password)
      log("#{@password} | #{password}")
    end
  end
end

module Crystal::Chat
  get "/" do
    user = User.new
    user.email = "test@test.com"
    user.password = "pass1234"
    user.save

    "Hello World! #{VERSION}"
  end

  Kemal.run
end

@fridgerator
Crypto::Bcrypt::Password.create(password).to_s

@Sly777
But after that, How can I cast to Bcrypt again to compare password?
Btw. I'm really new on crystal so It can be dumb question :D
Nick Franken
@fridgerator
something lilke
def password_valid?(password : String) : Bool
  Crypto::Bcrypt::Password.new(@encrypted_password) == password
end
Ilker Güller
@Sly777
Thanks @fridgerator !

<gcds> yay... the same error I had on my machine is now on CircleCI :⁠D

@luislavena
@gcds CircleCI for OSX? Same solution you applied locally you might want to apply to CI, might recommend install newer OpenSSL using Homebrew.

@FromIRC
<gcds> @luislavena, Locally I just used PKG_CONFIG_PATH flags to help find brew version of openssl so it worked out, but I have no idea how to fix circleci build.
<gcds> ahhh its osx build
<gcds> now I got it :⁠D
From IRC (bridge bot)
@FromIRC
<gcds> hmm it did not worked like I expected trying something out :⁠(
From IRC (bridge bot)
@FromIRC
<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.
Ghost
@ghost~55586c4815522ed4b3e08557
@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

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 :)

@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 :-)

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

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