Features

Object-oriented

Inheritance

class Triangle from Shape {
  New() {
    Parent();
  }
}

Interfaces

class Triangle from Shape implements Color {
  New() {
    Parent();
  }

  method : public : GetRgb() ~ Int {
    return 0xadd8e6;
  }
}

interface Color {
  method : virtual : public : GetRgb() ~ Int;
}

Type Inference

value := "Hello World!";
value->Size()->PrintLine();

Anonymous Classes

interface Greetings {
  method : virtual : public : SayHi() ~ Nil;
}

class Hello {
  function : Main(args : String[]) ~ Nil {
    hey := Base->New() implements Greetings {
      New() {}

      method : public : SayHi() ~ Nil {
        "Hey..."->PrintLine();
      }
    };
}

Reflection

klass := "Hello World!"->GetClass();
klass->GetName()->PrintLine();
klass->GetMethodNumber()->PrintLine();

Dependency Injection

value := Class->Instance("System.String")->As(String);
value += "510";
value->PrintLine();

Generics

map := Collection.Map->New()<IntRef, String>;
map->Insert(415, "San Francisco");
map->Insert(510, "Oakland");
map->Insert(408, "Sunnyvale");
map->ToString()->PrintLine();

Type Boxing

list := Collection.List->New()<IntRef>;
list->AddBack(17);
list->AddFront(4);
(list->Back() + list->Front())->PrintLine();

Static import

use function Int;

class Test {
  function : Main(args : String[]) ~ Nil {
    Abs(-256)->Sqrt()->PrintLine();
  }
}

Serialization

serializer := System.IO.Serializer->New();
serializer->Write(map);
serializer->Write("Fin.");
bytes := serializer->Serialize();
bytes->Size()->PrintLine();

Functional

Closures and Lambda Expressions

funcs := Vector->New()<FuncRef<IntRef>>;
each(i : 10) {
  funcs->AddBack(FuncRef->New(\() ~ IntRef : () 
    => i->Factorial() * funcs->Size())<IntRef>);
};

each(i : funcs) {
  value := funcs->Get(i)<FuncRef>;
  func := value->Get();
  func()->Get()->PrintLine();
};

First-Class Functions

@f : static : (Int) ~ Int;
@g : static : (Int) ~ Int;

function : Main(args : String[]) ~ Nil {
  compose := Composer(F(Int) ~ Int, G(Int) ~ Int);
  compose(13)->PrintLine();
}

function : F(a : Int) ~ Int {
  return a + 14;
}

function : G(a : Int) ~ Int {
  return a + 15;
}

function : native : Compose(x : Int) ~ Int {
  return @f(@g(x));
}

function : Composer(f : (Int) ~ Int, g : (Int) ~ Int) ~ (Int) ~ Int {
  @f := f;
  @g := g;
  return Compose(Int) ~ Int;
}

Host Support

Unicode

"Καλημέρα κόσμε"->PrintLine();

File System

content := Sytem.IO.Filesystem.FileReader->ReadFile(filename);
content->Size()->PrintLine();
Sytem.IO.Filesystem.File->Size(filename)->PrintLine();

Sockets

socket->WriteString("GET / HTTP/1.1\nHost:google.com\nUser Agent: Mozilla/5.0 (compatible)\nConnection: Close\n\n");
line := socket->ReadString();
while(line <> Nil & line->Size() > 0) {
  line->PrintLine();  
  line := socket->ReadString();
};
socket->Close();

Named Pipes

pipe := System.IO.Pipe->New("foobar", Pipe->Mode->CREATE);
if(pipe->Connect()) {
  pipe->ReadLine()->PrintLine();
  pipe->WriteString("Hi Ya!");
  pipe->Close();
};

Threads

class CaculateThread from Thread {
  ...
  @inc_mutex : static : ThreadMutex;

  New() {
    @inc_mutex := ThreadMutex->New("inc_mutex");
  }
  
  method : public : Run(param : System.Base) ~ Nil {
    Compute();
  }

  method : native : Compute() ~ Nil {
    y : Int;

    while(true) {
      critical(@inc_mutex) {
        y := @current_line;
        @current_line+=1;
      };
      ...
    };
  }
}
