Shiika

A statically-typed programming language.

Example

    class A
      def fib(n: Int) -> Int
        if n < 3
          1
        else
          fib(n-1) + fib(n-2)
        end
      end
    end
    A.new.fib(34)

Status

Early-alpha

Implementation (Rust, src/*)

• Implement class method (eg. Math.pow)
• Implement .new
• Local variables
• break
• String
• Array
• Instance variables
• Blocks
• Constant
  • Toplevel
  • Namespaced (eg. A::FOO)
• Modules
• Enums
• ...

TODO

• lambda/function(block)
• Module (like Ruby's Module)
• Enum
• Constants
• Check all ivars will be initialized (like Swift)
• ...

Type system (Prototype in Ruby, lib/*)

• Class method, instance method
• Basic generics
• Variable-length arguments
• Array literal
• Inheritance

Example

    class Pair<S, T>
      def initialize(@a: S, @b: T)
      end

      def fst -> S; @a; end
      def snd -> T; @b; end
    end
    Pair<Int, Bool>.new(1, true).fst

Development

Prerequisits

• Rust
• LLVM (brew intall llvm@7)
• bdw-gc 7.6.0 (Currently the path is hardcorded in src/main.rs. PR welcome)
• Ruby (used to generate boiler-plate library definitions)

Compile

$ bundle install
$ rake build

Run tests

$ rake test
