Tutorial

1. Build and Install

sudo pacman -S clang boost llvm
Build and install

For example,

git clone [email protected]:yutopp/rill.git
cd rill
mkdir build
cd build
cmake ../. -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang
make
sudo make install

2. Hello World

rillc helloworld.rill
helloworld

helloworld.rill

def main():int {
  printf("Hello World\n")
}

3. Variable

mutable variable.

val a: mutable(int) = 10;

and assign variable.

a = 20

immutable variable and type inference.

val b = 20;

We cannot rewrite a immutable variable.

b = 10 // error

Type

Class

mutable class. ctor is constructor. mutable class initialize like mutable(TestClass)().

def main(): int
{
    val klass1 = mutable(TestClass)();
    klass1.a = 1192;
    p(klass1.a);

    return 0;
}

class TestClass
{
    def ctor()
    {
        this.a = 10;
    }
    val a: mutable(int);
}

immutable class. immutable class initialize like TestClass().

def main(): int
{
    val klass2 = TestClass();
    p(klass2.a);

    return 0;
}

class TestClass
{
    def ctor()
    {
        this.a = 10;
    }
    val a: mutable(int);
}

overload constructor

def main(): int
{
    val klass2 = TestClass(20);
    p(klass2.a);

    return 0;
}

class TestClass
{
    def ctor()
    {
        this.a = 10;
    }

    def ctor(val i: int)
    {
        this.a = i;
    }
    val a: mutable(int);
}

output

20

Template Function

def main(): int
{
    val a = 20;
    val b = f(a);
    p(b);
    return 0;
}

template(T: type)
def f(val a: T): T
{
    val v: mutable(T) = 150;
    v = 10;
    return a * v;
}
