Open source projects

Lit lang (Github)

My first attempt at programming language design. Lit is a simple functional programming language.

Here's a sample of its (current) syntax:

let fib = fn { |n|
  if (n < 2) { return n; }

  return fib(n - 1) + fib(n - 2);
}

let n = gets();

puts("The # {n} fibonacci number is {fib(n)}")

Benchable (Github)

Benchable aims to make creating Ruby benchmarks easier.

Benchable.bench do
  setup do
    @array = (1..1000000).map { rand }
  end

  bench 'sort' do
    @array.dup.sort
  end

  bench 'sort!' do
    @array.dup.sort!
  end
end
# Output:
#                            user     system      total        real
# Sort                   0.400133   0.011995   0.412128 (  0.412339)
# Sort!                  0.388636   0.003980   0.392616 (  0.393054)

There are 4 benchmark types available: bm, bmbm, ips and memory.

EzAttributes (Github)

Easily define initializers with keyword args (in Ruby).

class User
  extend EzAttributes

  # Here name and age are required, and email has a default value, so it is optional.
  attributes :name, :age, email: 'guest@user.com'
end

user = User.new(name: 'Matz', age: 22)
# => #<User:0x000055bac152f130 @name="Matz", @age=22, @email="guest@user.com">

# EzAttributes will add getters for all fields too.
user.name
# => "Matz"
