Rawr Lang

Rawrlang is a powerful and expressive hybrid programming language that compiles to PHP. It fixes several issues in the language and implements functional concepts, with a syntax Python based and support for LiveScript operators (functions).

Examples

Hello World!

module Main
  ~IO::write "Hello World!"
end

Map Implementation

module Implementation
  exposing map
  import {tail, head} from Prelude
  
  define map (fn :: Fun, list :: array)
    let [x, xs] = [~head list, ~tail list]
    return switch xs
    | []        = []
    | otherwise = (~fn x) ++ (~map fn, list)
  end
end

Console I/O

module Main
  ~IO::getLine! >>= *IO::putStrLn 
end

Write in File

module TestFile
  with filepath as ~IO::getLine! do
    filepath.toFile! >> open "r" >> puts ~IO::getLine!
  end
end

Inheritance and Contracts

contract AnimalContract
  should walk (step :: int)
end

blueprint Animal
  with contract AnimalContract
  
  protected member step, name
  
  (@name) -> name

  method walk (_ :: int)
    @step += ...
  end
end

blueprint Cat
  inherit Animal
  
  (@name) ->
    ~parent::__construct @name
  end
  
  method DominateTheWorld
    % World has already been dominated by them.
    return True
  end
end
